Cannot use BusinessDataRepository in JAX-RS resources

0

Hi Axon.ivy team,

I know this questions had been asked long time ago at https://answers.axonivy.com/questions/2777/can-not-use-ivy-repo-in-resfulapi. But the question was for Axon.ivy 6.3.0 and there was never a resolution of the issue.

I am using Axon.ivy 7.0.8 LTS and I still encountered the same issue.

I introduce a JAX-RS resource:

package com.example.lab;

@PermitAll
@Path("awesome")
public class TheAwesomeApi {

    @POST
    @Consume("application/json")
    @Produces("text/plain")
    public String saveAwesomeMessage(AwesomeMessage message) {
        return Ivy.repo().save(message).getId();
    }

    public static class AwesomeMessage {
        private String content;
        // getter, setter
    }
}

When I tried to call this API, the exception was returned.

curl http://localhost:8081/ivy/api/designer/awesome \
  -H 'Content-Type: application/json' \
  -d '{ "content" : "This is an awesome message" }'

full stacktrace can be found here: https://pastebin.com/hXcyQq6h

Is this issue still a known limitation even with the 7.0 LTS?

Thanks for your support!

The BusinessDataRepository is designed and powerful because the data in it is usually attached to a IBusinessCase. So it makes sort of sense to me that the example here does not work with the ivy.repo() API as there is no Task or Case set up when a client uses the REST api.

But the relation (between repo & BusinessData) is not strictly enforced and lives in a separate db table. So it looks like a minor bug to me. I opened an issue for it: https://jira.axonivy.com/jira/browse/XIVY-3074

Workaround up till then: store data that is associated with a IBusinessCase in a process. Within it you have a Task/Case.

Yeah I see. The most common use case is to use the repo in combination with a BusinessCase. But the relation is not strictly enforced and lives in a separate db table. So it looks like a minor bug to me. I opened an issue for it: https://jira.axonivy.com/jira/browse/XIVY-3074

With today's nightly build this issue has been resolved. You can download the newest 7.3.0-SNAPSHOT here and try it out: https://developer.axonivy.com/download/nightly

Hi Andreas Rusch and Reguel Wermelinger, thanks for the update and quick action to fix the issue! Is there any chance that the fix could be backported to 7.0 LTS? We don't have the option to upgrade to Leading Edge for the time being.

(02.02.2019 at 03:07) vagabond vagabond's gravatar image

Yes, we are planning to add this feature in 7.0.11.
