<div class="jive-rendered-content"><p>Hello. Is there a way to register domain specific work item handlers via Spring configuration? There is an example in the manual on how to create such nodes: <a class="jive-link-external-small" href="https://hudson.jboss.org/hudson/job/jBPM5/lastSuccessfulBuild/artifact/target/jbpm-5.0-SNAPSHOT-docs-build/jbpm-docs/html_single/index.html#d0e1542">https://hudson.jboss.org/hudson/job/jBPM5/lastSuccessfulBuild/artifact/target/jbpm-5.0-SNAPSHOT-docs-build/jbpm-docs/html_single/index.html#d0e1542</a></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>But I would like to inject EmailService to NotificationWorkItemHandler via Spring instead of doing this call:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre class="jive-pre"><code class="jive-code jive-java">     EmailService service = ServiceRegistry.getInstance().getEmailService();
