REST http method PATCH

renatostalder — Sun, 21 Jun 2020 06:22:29 -0400

Hi all We want to call a REST API with the method PATCH. But in the selector there is no such option. Is there a way to do it anyway? Thanks for the help.

Can I define REST API endpoint in a jar file?

ptgiang — Wed, 25 Mar 2020 04:40:40 -0400

Hello everyone,

I have a maven project (jar), for example, my-api. In this project, I defined a REST API endpoint:

@Path("/v1/dossiers")
public class MyAPI {

    @Path("/")
    public Response getDossiers() {
        // our logic
        return response;
    }
}

I have an ivy project, for example, my-app and I added the jar dependency my-api. I can't access the API above from client

But, I tried to create a my-api as an ivy project (iar) and added it as an iar dependency my-app. It works well.

My question is: Can I define the REST API endpoint in a jar file? If yes, how can I do that?

P/s: We're using Ivy 7.0.11

Getting error when following the REST API guide

Hi. I'm trying to follow the guide here: http://developer.axonivy.com/doc/7.3.1/DesignerGuideHtml/ivy.integration.html#ivy.integration.rest and all I'm getting is a stacktrace:

None of the classes in the stacktrace belong to my project, so it doesn't seem to be an error with my code per se. Any idea what might be wrong?

Using the Dialog REST api for Data

TareqK — Thu, 19 Mar 2020 05:56:52 -0400

Hello, So as I know, each HTML dialog has a rest api to access its methods using the /rest/method/methodName relative to the dialog base. I was wondering if it is possible to do the same with data, using /rest/data/dataParam in the same way.

Can not add @Provider to handle an specific exception for rest api

ptgiang — Fri, 13 Mar 2020 06:10:26 -0400

hi all,

I'm creating a rest API for one application. It's working now. I would like to handle some specific exceptions and to return some specific data responses. I used @Provider from javax.ws.rs.ext.Provider to handle it, but I got an error 500.

import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.Status;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;
import ch.axonivy.fintech.export.dossier.exception.RecordNotFoundException;
import ch.axonivy.fintech.export.dossier.response.ExportingErrorResponse;

@Provider
public class RecordNotFoundExceptionMapper implements ExceptionMapper<RecordNotFoundException> {

    @Override
    public Response toResponse(RecordNotFoundException ex) {
        ExportingErrorResponse response = new ExportingErrorResponse();
        response.setStatusCode(Status.NOT_FOUND.getStatusCode());
        response.setErrorMessage(ex.getMessage());

        return Response.status(response.getStatusCode()).entity(response).type(MediaType.APPLICATION_JSON).build();
    }
}

The following is error:

Could you please give me some suggestions or any hints to overcome this issue? Thank you!

Engine Performance - Profiling

John Moser — Fri, 07 Feb 2020 04:14:06 -0500

Dear Ivy Team

My test setup is as follows : 4 CPU (i7, 3GHz), Xms128m, Xmx2048m

2 Browsers, every 3 seconds a click on the UI during 60 seconds

1 With visualvm it shows that Ivy spent approx 16s with reading, the issue is I can not quantify how much data it is (since your performance / rest client logging is not working). But my guess is, it can only be a few hundred KB in total.

=> 16s seem to me a lot, can you confirm my results ?

2 Rest Client - java > Ivy.rest() : is Ivy.rest() client pooled ? (since the Rest Clients are pretty heavy weight they should be pooled otherwise memory consumption skyrockets and also performance will degrade if they are used like in a micro services architecture)

=> Ivy.rest() did you do any performance analysis ? Is this the "required" way of using Rest Client in Ivy ?

Complete Task from REST

Stelt0 — Mon, 07 Oct 2019 09:40:24 -0400

Hi Ivy Team,

How to complete a task from REST service in Axon.Ivy ?

So, far I saw that I can do .destroy() but it doesn`t feel the right, I believe that there will be some side effects

.setActivator(ivy.session.getSecurityContext().getSystemUser()) but this way I`m loosing the history who was the assignee of the task

Any other options ?

Maybe to do HTTP call to the end-point /TaskA.iot?taskId=7

My goal is to build REST API that can manage the Axon.Ivy tasks from external system.

Best Regards, Yordan

REST API and JSESSIONID

How to change the category name of the log when calling REST client by using Ivy.rest().client(...) ?

Lieu Vo — Thu, 29 Aug 2019 04:11:43 -0400

When I call any REST clients by using Ivy.rest().client(...), it will have the log with the category name [rest_client] from IVY Core. However, I want to make the log messages written into the specific log files of each services. With the same category name for all REST services like this, I could not find any way to configure in log4jconfig.xml to make it correct.

If anyone have ideas to change that category name or change the log4j configuration, please help.

Thanks in advance.

Consuming Rest in Plugin Project

Genzer Hawker — Mon, 03 Jun 2019 09:22:49 -0400

Currently, I face the difficulties that there are some lacking libraries when I consuming rest API in Ivy plugin I follow this instruction : https://answers.axonivy.com/questions/2477/how-to-register-my-code-that-runs-on-every-engine-startup When user logs in, logs out or gets time-out, I want to call rest service to do some stuff:

But I get an error like this when calling rest service in the plugin:

Currently, I just add some dependencies like this picture into the plugin but it doesn't work

Do you have any hint or any suggestion for this problem? Thanks in advance :)

How to upload a File to a REST api

SupportIvyTeam — Thu, 18 Apr 2019 04:05:19 -0400

I am building a document management service with a RESTful API.

@Path("fileUpload")
public class FileUploadService
{
  @PUT
  @Produces(MediaType.APPLICATION_JSON)
  @Consumes(MediaType.MULTIPART_FORM_DATA)
  public Response uploadFile(@FormDataParam("file") InputStream fileStream,
          @FormDataParam("file") FormDataContentDisposition fileDetail) throws IOException
  {
   .... 
  }
}

It seems to work as expected if I use a third party client such as Postman. However, when using the REST activity of ivy I am unable to call this service. I always get errors stating the the header X-Requested-By is missing. Whats the issue? How can I send files using a REST Client Call activity?

Streaming with Ivy REST API

John Moser — Tue, 08 Jan 2019 10:00:55 -0500

Dear Ivy Team

I have the following case: User should be able to upload scanned documents (1...xx MB) via Ivy and the data should be streamed through the REST service (layers). Since each REST service decouples (therefore no shared memory) the memory required to transport the document data could be quite high. To avoid that I would like to stream the data down to the persistency layer.

Problem: Currently I am trying to pass binary data -> "In Inscribe Rest Service Call Activity" -> Body, entity -> binary data and content-type=application/octet-stream and read it by the consumer REST service with HttpServletRequest request->getInputStream(). Though here I get an error (InputStream seems to be already closed).

Question: Is this approach correct or do I have to use multipart/form-data (if yes, do you have an example, especially if the call is executed by the Ivy REST client).

Thanks in advance for a feedback.

Best Regards John

Does ivy RestAPI require @Path on class body?

trungdv — Tue, 23 Oct 2018 07:51:47 -0400

Hi ivyteam

I'm using ivy 7.0.3 to develop RestAPI.

Now i have a api as below

On the right side i define @Path on class body but the left side.

The right it works well on designer and engine. The left only works for Designer. on engine it say restAPI not found (already restart ivy engine)

Does ivy require @Path on class body?

Thanks

Calling NTLM protected REST service with SSO

peters — Mon, 08 Oct 2018 05:45:55 -0400

In Ivy 7.1, is it possible to call a NTLM protected web service using the logged in user (therefore not configuring user/password in the REST client)?

How can I use JAX-RS ContainerRequestFilter/ResponseFilter for my JAX-RS resources.

Genzer Hawker — Mon, 10 Sep 2018 02:24:40 -0400

Hi,

I want to implement my own ContainerRequestFilter and ContainerResponseFilter for my JAX-RS resources in my Axon.ivy projects. Typically, I would create an implementation of the filter:

import java.util.logging.*;

@Provider
 public class MyRequestFilter implements ContainerRequestFilter {
    @Override
    public void filter(ContainerRequestContext requestContext)
            throws IOException {
        Logger.getLogger("Test").log(Level.WARNING, "LOOK MA! IT WORKS");
    }
}

I assume that Jersey will register my filter and it will works. However, I got

javax.servlet.ServletException: java.lang.IllegalStateException: Request scope has been already shut down.
        at org.glassfish.jersey.servlet.WebComponent.serviceImpl(WebComponent.java:489)

..when I call my resources.

Is it possible (at all) to use ContainerRequestFilter/ResponseFilter (and Feature, DynamicFeature) in an Axon.ivy project? And without introducing JAR files into webapps/ivy/WEB-INF/lib/?

Thanks

Ivy 7.1 Rest API basic authorization

thminh — Tue, 26 Jun 2018 02:59:25 -0400

I'm trying to create a test REST API in Ivy version 7.1 like the below: then test it on Postman and get this response:

Moreover, when I try to access the API by Chrome browser.

First time attempt: Then cancel it and get this response: Then press F5 and I get this response:

According to the last comment on this topic https://answers.axonivy.com/questions/1858/rest-service-security

The REST service provided by Axon.ivy are be default protected by HTTP BASIC Authentication.

So my question is that why I could access the API without the basic authorization on Postman? I also test with the same scenario in Ivy version 6.2 but I'm unable to access the API without the basic authorization. Thanks

How to secure Rest Services from Ivy 6.2 with Authorization Bearer instead of Basic

How to get the URL of a process start within a JAX-RS class

Emmanuel Comba — Wed, 18 Apr 2018 15:06:23 -0400

Hello IvyTeam,

My Ivy Version : 7.0.3 I would like to get the url from a process in a JAX-RS Rest Resource but I get an Exception with this code:

Ivy.html().startref("Functional Processes/dis/videoIdentification/start.ivp")

The JAX-RS Resource is located in the same project as the process. It works without problem in a Process (IvyScript Step).

I can imagine that the fact the code is in a JAX-RS Resource does not allow accessing some Ivy resources like the ProjectModelVersion Provider. Is there a workaround for that? Or do I have to compute the url more manually with the InetAddress and so on ? By the way this code works in this resource: Ivy.html().applicationHomeRef()

Thanks in advance

Here the StackTrace I get:

Zombie task is created after finishing callable subprocess. How to avoid it?

trungdv — Fri, 27 Oct 2017 01:55:45 -0400

Hi all

We're using ivy 6.3, and have face the problem that we implement a restfulAPI by java code, when we trigger the callable subprocess from it. After callablesub is finished, it will remain a zombie task. Why i need to call ivy subprocess from api? Answer: i need to call ivy.repo() to persist my data then response the id. This api can't be called in restful.

Here is my callable subprocess:

and it's the code of api:

@Path("{applicationName}/individualch")
@Produces(MediaType.APPLICATION_JSON)
public class IndividualchApi  {

    /**
     * This API is used by third party application when it want to call
     * to create dossier Response message is cobId
     * @param provider
     * @param externalId
     * @param sobDossier
     * @return
     */
    @POST
    @Path("/dossiers")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
            public Response createIndividualCHDossier(@NotNull  String provider,  @NotNull String externalId, SobDossier sobDossier) {
        if (StringUtils.isBlank(provider) || StringUtils.isBlank(externalId) || sobDossier == null) {
          return Response.status(Status.BAD_REQUEST).entity(new ResponseExceptionMessage()
                .errorCode(DossierCreationServiceExceptionType.BAD_REQUEST.getUniqueCode().toString())
                .message("Invalid params")).build();
      }
        return new CreateDossierHandlerService().createIndividualCHDossier(provider, externalId, sobDossier);
    }
}

And here is the way we trigger subprocess from service:

SubProcessCallResult callResult = SubProcessCall.withPath(CREATE_DOSSIER_HANDLER_PROCESS_NAME)
                    .withStartSignature("createDossier(String,String,SobDossier)")
                    .withParam(PARAM_PROVIDER, provider).withParam(PARAM_EXTERNAL_ID, externalId)
                    .withParam(PARAM_SOB_DOSSIER, sobDossier)
                    .call();

My Question:

Is it a good solution to go? I actually can't call ivy.repo() inside my service. How can we prevent this kind of zomebie task?
If we can't prevent zombie task, how ivy handle this kind of task? Does ivy clean it up automatically?

Thanks all

REST token authentication

Marco Klauenbösch — Mon, 23 Oct 2017 10:08:48 -0400

We’ve been setting up a REST client but failed at configure the authentication. The API requires you to authenticate with a token.

The documentation of the API tells you to pass the token through the «Authorization» header with its value being for example «Token: d2f763479f703d80de0ec15254237bc651f9cdc0». Doing this in the REST Client Activity element wasn’t successfully.

So, what’s the correct way to pass the token to the API for authentication

Can we use Swagger in Ivy Project?

trungdv — Fri, 01 Sep 2017 07:02:51 -0400

Hi all

Now i'm using Axon ivy 6.3. In my project, i have created an Restful API following the OpenAPI Specification

Now i want to use Swagger to generate YAML file from those API (follow this guideline and this post).

Here is my web.xml

and this is my Servlet:

public class ApiScanner extends HttpServlet {
    private static final long serialVersionUID = -4192689550210212169L;

    @Override
    public void init(ServletConfig config) throws ServletException {
        super.init(config);

        BeanConfig beanConfig = new BeanConfig();
        beanConfig.setVersion("1.0.0");
        beanConfig.setSchemes(new String[]{"http"});
        beanConfig.setHost("localhost:8081");
        beanConfig.setBasePath("/ivy/api/designer");
        beanConfig.setResourcePackage("ch.axonivy.fintech.mybank.website.dossier.api");
        beanConfig.setScan(true);
    }
}

But nothing happen after i restart ivy. Has anybody tried it before?

Thanks

Can I accept self signed certificates in REST requests?

SupportIvyTeam — Tue, 29 Aug 2017 07:54:28 -0400

In my project I am forced to use a third party REST service which is only accessible over HTTPS. Unfortunately the certificate is self signed. What can I do to accept untrusted certifticates?

Is it possible to access Ivy's RESTful API from an HtmlDialog or within the same session?

Genzer Hawker — Wed, 22 Feb 2017 08:26:22 -0500

Hi Ivy Team

I have a HtmlDialog containing several links to our RESTful API (implemented using Axon.ivy). However, every time the user accesses to the API, the browser requires authentication even though the user has already logged in.

I'm aware of the javax.annotation.security.PermitAll/DenyAll (-- which seems to be the only annotations supported?) but I want to keep the Basic authentication intact.

Say the page could be like this:

< !-- The HelloWorld dialog -->
< h:html>
    < h:body>
        < h:outputLink value="/ivy/api/designer/helloworld" target="_blank">
            Click to see Hello World
         < /h:outputLink>

        < h:outputLink value="/ivy/file/designer/session/some_file_already_created.txt" target="_blank">
            Get content of file
        < /h:outputLink>
    < h:/body>
< /h:html>

The first link will require authentication whereas the second works normally.

Is there a possible way to overcome this?

Is WADL as description of REST services supported?

Reto Weiss — Wed, 18 Jan 2017 15:34:40 -0500

JAX-RS method returns StreamingOutput fails with "Access to ivy environment outside a process request thread is not possible"

Genzer Hawker — Mon, 03 Oct 2016 14:50:20 -0400

Hi Ivy team

I want to build a JAX-RS API returning response in a streaming manner (chunked transfer encoding). The code looks like below:

@Path("{applicationName}/streams")
public class StreamingResponseRestSResource {

    @GET
    public Response getStreamingResponse() {

        // This works by keeping a reference then pass it to the anonymous class.
        // It may NOT work in all situations.
        final Logger logger = Ivy.log();


        StreamingOutput streamingOutput = new StreamingOutput() {

            @Override
            public void write(OutputStream output) throws IOException,
                    WebApplicationException {

                PrintWriter out = new PrintWriter(new BufferedWriter(
                        new OutputStreamWriter(output)), true);

                Ivy.log().error("HHH - BREAK HERE");

                logger.error("HHH - It works with passed reference of Logger");

                IntStream.range(0, 100_000)
                    .forEach(c -> out.println("HHH - Count up to " + c));

            }
        };

        return Response.ok(streamingOutput).build();
    }
}

Full code here: http://pastebin.com/tEAMGFB3

If I do

curl -i -u Developer:Developer http://localhost:8081/ivy/api/designer/streams

the response would be:

{ "errorId": "1578A42A15718503", "errorMessage": "Access to ivy environment outside a process request thread is not possible.\nCurrent thread: Thread[http-nio-8081-exec-14,5,main]", "statusCode": 500 }

If I comment out the line ...

Ivy.log().error("HHH - BREAK HERE");

...the error disappears.

Is there anyway to fix the access to Ivy with StreamingOutput implementation?

How can I analyze or log the root cause of my failing REST webservice call?

Axon ivy mobile experience

Stelt0 — Mon, 08 Aug 2016 10:26:03 -0400

Hello Ivy Team,

I want to provide some mobile experience to my users.

There are currently 3 approaches in my head:

1.Native Mobile Client - Native iOS and/or Android app - no Web View - communicating to Ivy via HTTP - only data returned, no HTML - offline support

2.Hybrid Mobile Client - Phonegap or Ionic HTML SPA hosted on the device (web view) - communicating to Ivy via HTTP - only data returned, no HTML - offline support

3.Mobile optimized web view - OOTB provided by Ivy web technologies - JSF and PrimeFaces - no offline support

Option 3 is the easiest to implement and release, but it has the worse UX. My biggest concern for option 1 and 2 is the security in terms of session management.

Witch approach would Ivy Team recommend ? I saw in the documentation about the Offline User Dialogs, but they goes to option 1

Best Regards, Yordan Yunchov

Ajax call from HTML Dialog to consume Web Service and REST Service

Stelt0 — Thu, 23 Jun 2016 17:40:38 -0400

Hi All,

I have the situation where from HTML dialog I need to make custom Ajax call to ivy Web Service in the same process. I`m wandering what would be the implications of this approach regarding the security context.

The Ajax call will send a HTTP request with the cookie session of the currently logged user. Will this be enough for ivy engine to identify the user ?

This question is also valid for the future release 6.2 when it comes to REST services.

Best Regards, Yordan
