https://answers.axonivy.com/questions/3641/cannot-use-businessdatarepository-in-jax-rs-resources<p>Hi Axon.ivy team,</p> <p>I know this questions had been asked long time ago at <a href="https://answers.axonivy.com/questions/2777/can-not-use-ivy-repo-in-resfulapi.">https://answers.axonivy.com/questions/2777/can-not-use-ivy-repo-in-resfulapi.</a> But the question was for Axon.ivy 6.3.0 and there was never a resolution of the issue.</p> <p>I am using Axon.ivy 7.0.8 LTS and I still encountered the same issue.</p> <p>I introduce a JAX-RS resource:</p> <pre><code>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 } } </code></pre> <p>When I tried to call this API, the exception was returned.</p> <pre><code>curl <a href="http://localhost:8081/ivy/api/designer/awesome">http://localhost:8081/ivy/api/designer/awesome</a> \ -H 'Content-Type: application/json' \ -d '{ "content" : "This is an awesome message" }' </code></pre> <blockquote> <p>full stacktrace can be found here: <a href="https://pastebin.com/hXcyQq6h">https://pastebin.com/hXcyQq6h</a></p> </blockquote> <p>Unable to provision, see the following errors:</p> <pre><code>1) Error in custom provider, java.lang.NullPointerException while locating ch.ivyteam.ivy.scripting.dataclass.internal.di.IvyCaseProjectClassLoaderProvider

</code></pre> <p>Is this issue still a known limitation even with the 7.0 LTS?</p> <p>Thanks for your support!</p> <p>Jack</p>enTue, 29 Jan 2019 03:39:23 -0500https://answers.axonivy.com/questions/3641/cannot-use-businessdatarepository-in-jax-rs-resources/3643<p>The <a href="https://developer.axonivy.com/doc/latest/PublicAPI/ch/ivyteam/ivy/business/data/store/BusinessDataRepository.html">BusinessDataRepository</a> is designed and powerful because the data in it is usually attached to a <a href="https://developer.axonivy.com/doc/latest/PublicAPI/ch/ivyteam/ivy/workflow/businesscase/IBusinessCase.html">IBusinessCase</a>. 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.</p> <p>But the relation (between repo &amp; 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: <a href="https://jira.axonivy.com/jira/browse/XIVY-3074">https://jira.axonivy.com/jira/browse/XIVY-3074</a></p> <p>Workaround up till then: store data that is associated with a <a href="https://developer.axonivy.com/doc/latest/PublicAPI/ch/ivyteam/ivy/workflow/businesscase/IBusinessCase.html">IBusinessCase</a> in a process. Within it you have a Task/Case.</p>Reguel WermelingerTue, 29 Jan 2019 03:39:23 -0500https://answers.axonivy.com/questions/3641/cannot-use-businessdatarepository-in-jax-rs-resources/3643
