Hi! I ceated a hook of &#34;service wrapper&#34; type  and getting the following exception.  2019-12-16 13:31:55.839 ERROR [localhost-startStop-1][ServiceWrapperRegistry:77] Unable to get service bag for class com.example.hook.CustomDDMStructureLocalService<br />java.lang.IllegalArgumentException<br />    at com.liferay.registry.internal.RegistryImpl.getService(RegistryImpl.java:160)<br />    at com.liferay.portal.deploy.hot.ServiceWrapperRegistry$ServiceWrapperServiceTrackerCustomizer._getServiceBag(ServiceWrapperRegistry.java:140)<br />    at com.liferay.portal.deploy.hot.ServiceWrapperRegistry$ServiceWrapperServiceTrackerCustomizer.addingService(ServiceWrapperRegistry.java:74)<br />    at com.liferay.portal.deploy.hot.ServiceWrapperRegistry$ServiceWrapperServiceTrackerCustomizer.addingService(ServiceWrapperRegistry.java:61). <br />The hook works fine when I deploy it on tomcat already started. But when I restart tomcat it thow this exception. I have to deploy it again. Is like when the hook is deployed, the ddmStructureLocalService instance is not initialized yet. <br />Anyone can help me with this?<br /><br />Thanks in advance!
