AXIS web service client calls LinkageError with Policy

Alex Suter — Thu, 12 Mar 2020 01:45:20 -0400

Since Axon.ivy 8.0 you may have problems with AXIS web service client calls, which you will notice in the log as follows:

LinkageError: loader constraint violation: loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @4797c3e2 wants to load class org.apache.neethi.Policy. A different class with the same name was previously loaded by org.eclipse.osgi.internal.loader.EquinoxClassLoader @59b5251d. (org.apache.neethi.Policy is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @59b5251d, parent loader 'platform')

This problem occurs in combination with web service policies. To fix this issue, you need to migrate to the CXF Web Service Client technology - the AXIS stack is deprecated.

We have invested heavily in the new CXF technology in the Web Service Call Stack . If you have any problems with CXF, please contact us. We will take our time and make the CXF stack even better 💪!

CXF Web Service Client improvements in 8.0.3

Alex Suter — Thu, 05 Mar 2020 02:33:11 -0500

By default CXF Web Service Calls runs by default with HttpUrlConnection of Java. HttpUrlConnection is limited when it comes to authenticate against a NTML web service.

CXF provides the ability to change the implementation of the connection itself to org.apache.http.nio.client.HttpAsyncClient. Besides the full support of NTML it also provides better performance. Due that fact we changed the default connection to HttpAsyncClient of CXF Web Service Calls.

There are no known compatibility issues between these to implementations. If you face one, please contact us. And you are always still able to fallback by setting the use.async.http.conduit to false on the Web Service Client.

axis2 socket max timeout value

fabien — Tue, 04 Feb 2020 09:26:48 -0500

Hi,

I have a max timeout on socket connection with Ivy 5.1 when I use a web service node. Is it a way to modify this value in this version of Ivy ?

I tried with web.xml and java option but do nothing.. And I can't find anything in the server variable configuration..

Any hint will be very appreciate.

Thanks in advance.

multiple exceptions lead to ivy:error:loop

Adrian Imfeld — Wed, 11 Dec 2019 09:41:15 -0500

Hi there

We get an "ivy:error:loop" exception by Ivy in a loop. In this loop, we send some ws calls in a Callable Sub. Possibles exceptions are not handled in the Callable Process, but are caught by a "Inscribe Error Boundary Event" on the Callable Sub Element. The loop-exception occurs when we receive an exception (ivy:error:webservice:exception) in this Callable Sub twice.

From our point of view one task could easily receive more than one identical exception during its execution. Ivy should not send a loop-exception in this case.

Why does Ivy react like that? Have we done something wrong?
Is there a solution or workaround for our problem?

How the read a webservice wsdl over https

Bruno Bütler — Thu, 07 Mar 2019 10:11:28 -0500

I have to generate a webservice client in ivy7.2 (CXF) where the wsdl is only accessable over https.

The WebsService class generation crahes with a mysterious exception:

org.apache.cxf.tools.common.ToolException: org.apache.cxf.wsdl11.WSDLRuntimeException: Fail to create wsdl definition 
WSDLException (at /definitions/types/xs:schema): faultCode=PARSER_ERROR: Problem parsing .xsd'.: org.xml.sax.SAXParseException: White spaces are required between publicId and systemId.

Apache CXF DateTime Converter with different Timezone

Adrian Imfeld — Mon, 26 Nov 2018 09:32:33 -0500

We have a simple WSDL which holds a datetime attribute. This attribute is converted correctly by the CXF library and holds the Ivy DateTime format in the generated ws class. When we pass a datetime into the ws call, the datetime is formatted as 2018-11-26T12:56:52+01:00 but the ws provider (in our case SAP) needs the datetime within the UTC timezone, like: 2018-11-26T12:56:52Z

How can we change the format? Is there a simple way, for example to pass the timezone to the Ivy DateTime object? ...or pass a SimpleDateFormat object for the string formatting?

Checking whether there is an endpoint in the web service or not

Tu Doan Quang — Tue, 02 Oct 2018 23:03:27 -0400

Hi everybody I would like to check there is an endpoint in the web service before I send data to there. I found an interface IWebServiceEndpoint, but I don't know how to use to get the data by Ivy API. Could someone help me? Thank you so much

Endless loop when calling a Webservice

Fotini Kalantidou — Fri, 21 Sep 2018 02:22:05 -0400

When calling an external Webservice we get a log of type: "The following requests seems to loop endless or are blocked:"

According to an answer in another post:

The endless loop logs occur when:

a normal user request is running for longer than 5 minutes
a system user task is running longer than 1 hour

How could be provoke such an error? And how could we prevent such an error when it occurs on a WebService call? Maybe by defining a Timeout on the Webservice call? Does a default timeout for the WS Call exist?

Delete obsolete variables and web services

DateTime in Webservice

tauser — Wed, 30 May 2018 04:07:00 -0400

Hello Ivy Team, we use one field with type DateTime in result by Web Service Process start. If there is null in this field, we receive always initialized Value

 <result>
            <exportTimestamp>0001-01-01T00:00:00+01:00</exportTimestamp>
 </result>

What is wrong on it?

I would expected, the section exportTimestamp would not be created (similar like with Type String).

Thank you for response in advance.

How to avoid policy error when calling SOAP Webservices

SupportIvyTeam — Wed, 11 Apr 2018 05:44:49 -0400

I'm integrating data from a remote SAP system over SOAP services. The SAP services WSDL contains Policy elements. At runtime the remote call fails with PolicyException: None of the policy alternatives can be satisfied. Does anybody know how to call such a service?

Prevent/by-pass ivy:error:loop

rhorber — Tue, 10 Apr 2018 09:45:14 -0400

Hello everyone

We have a process, where we parse a CSV file. For each line a web service is called (in a loop). Our error handling catches timeout and other errors with Error Start elements.

The problem now is, on the second timeout (or other) error, Ivy throws an ivy:error:loop error, because it is the same sender and receiver element as also the same task.

What are possible solutions for this problem? We can't send all lines at once, because the web service is third party, and also it is crucial to catch every error to handle it.

Any help will be appreciated.
Thanks.

Here's a picture of the process:

How to use WS-Addressing in a webservice call?

Can i turn on/off webservice authentication programmatically

trungdv — Thu, 01 Feb 2018 03:06:57 -0500

Hi all

We have a webservice which implemented on ivy. This service serve for many customer. As default it required basic-auth. Now some of customers dont want to be authenticated when calling it, so we intend to introduce the global var where admin can allow to turn on/off this feature.

Can we go with that way and how to turn off/on this authentication type programmatically?

Thanks

SOAP Webservice in Ivy using Java

Walter Weiss — Fri, 03 Nov 2017 11:36:49 -0400

I tried to publish a web service similar to the one described in the tutorial below. I did not use the out-of-the-box Ivy WS process as each of the WS have many methods (and decided to build them in Java instead).

Example

Using Endpoint.publish() I specified the location for the WS. However, this requires me to run the class containing this method in the java console, and then run Ivy. I tried tying Endpoint.publish() to a "Start Process" in Ivy but it did not work.

public class SOAPPublisher {

public static void main(String[] args) {
    Endpoint.publish("http://localhost:8888/ws/depotWS99", new WSDepotShopImpl());
}

Is there a "best practices" method to building a SOAP WS via Java in Ivy, and how do I get the WS published in Ivy? Thanks!

Mocking SOAP web services

SupportIvyTeam — Fri, 27 Oct 2017 10:20:49 -0400

My Ivy project needs to call a SOAP web service but I can’t connect to the server where this web service runs. The only thing I have is the corresponding .wsdl file.

Can I use it to mock the web service for development and testing?

Problem with German Umlaut in a Web Service wsdl

SupportIvyTeam — Mon, 19 Jun 2017 06:27:50 -0400

Hi all

I have to call a SOAP WebService provided by SAP Business Objects that contains a complex type definition with Germain Umlaut in the wsdl. If I try to generate the webservice client configuration in ivy I get: Error decoding WSDL: java.lang.Exception: Compile error...

It is obvious, that the generated Java code containing the Umlaut characters can not be compiled.

I know the workaround to call a WebService using Java with tools like SoapUI, but I wonder if there is a way to do it with standard ivy means.

Any hints are welcome.

How to handle date format with SOAP web service in Ivy

vhsvuong — Thu, 29 Sep 2016 07:51:06 -0400

Hi Everyone,

Now, I got the trouble with format date in SOAP webservice which created by Ivy

When I call it by SOAP client, I always got the exception like Unmarshalling Error: 28.08.2016 Because as we know, the expected format for date in XML is: YYYY-MM-DDThh:mm:ss. But I want to use the custom format like dd.MM.YYYY

Do you have any ideas about that?

Axis2 Date Converter

tiago — Wed, 10 Aug 2016 12:31:00 -0400

I'm calling a external web service with a "Web Service Step". The serialization of a java.util.Date field generates for example this line :: <documentdate>2016-08-10+01:00</documentdate>

Is there a way to change this behavior so the serialization converts the date to string without the timezone?

How can i call a http-session to an internet-url from ivy and to store some informations form the webpage-answer?

Dieter Staudt — Mon, 13 Jun 2016 13:52:04 -0400

Dear all,

we have the problem that the timestamp for storing in the database is the local timestamp where the database server is hosted. We need also the local time of the user request, sided all around the word.

To calculate the local time of the user there is a https-api-call via Google Maps and the answer will deliver the time zone with the off_set und the daylight saving time offset as diffenrce to UTC.

For example: Today it is 2016-06-13 09:45 CEST = 07:45 UTC; the API delivers for Sydney: 36000 Seconds offset and 0 Secondes dst-offset and for Berlin 3600 Seconds offset and 3600 Seconds dst-offset; I can now calculate Berlin Time - 1 Hour Offset - 1 Hour DST-Offset = UTC + 10 Hours = Sidney Local Time = 17:45

https://maps.googleapis.com/maps/api/timezone/xml?location=-33.510000,151.200000&timestamp=1696060417

Is is possible to do this with IVY or is thera an other way to get the local time of the staff's office?

Thanks in advance.

Best regards Dieter

Get IHttpRequest for SOAP web service

ivyUser — Wed, 16 Dec 2015 12:37:37 -0500

Hello everyone!

I would like to get an object that implements ch.ivyteam.ivy.request.IHttpRequest in order to extract the remote client's hostname.

A great solution for this problem has already been described here: http://answers.axonivy.com/questions/1055/access-ihttprequest-object

It works well when the type is set to "Business Process". However, I cannot cast the ivy.request to an IHttpRequest because it's always a ch.ivyteam.ivy.request.impl.ProcessRequest (since I'm using a different process type called "Web Service Process").

I have also tried to modify the generated JAX-WS class to achieve the same result (with no success so far).

What is the right way of doing this under Ivy 5.1?

Thank you in advance!
