FYI, I'm using Ivy Designer v6 s16.</p> <p>I did try to use CDI in my bean, it acknowledged the bean with <strong>@Named</strong> annotation; however, the service that I try to inject return null (throwing InvokeException &amp; NullPointerException). Though I know that Ivy Engine not yet supported CDI injection, I just want to know if there is any trick to go around it?</p>enWed, 30 Sep 2015 16:14:22 -0400https://answers.axonivy.com/questions/1496/is-it-possible-to-use-cdi-injection-or-spring-injection-in-ivy-project/1497<p>As you said the Ivy Engine does not support CDI injection. </p> <p>If you try to setup and use Spring then I think you will get into troubles with incompatible jars and or versions.</p> <p>In Ivy internally we use Google Guice for DI. This allows us to use @Inject, @Named annotations. To get an instance of a root class you can use:</p> <pre><code>import ch.ivyteam.di.restricted.DiCore; DiCore.getGlobalInjector().getInstance(YourService.class); </code></pre> <p>Note that this is not Public API and will be changed in future! If you want to use it I strongly suggest that you encapsulate the code in a project specific helper class, so that you only have to change the helper class once we change the internal API.</p>Reto WeissWed, 30 Sep 2015 16:14:22 -0400https://answers.axonivy.com/questions/1496/is-it-possible-to-use-cdi-injection-or-spring-injection-in-ivy-project/1497
