Recent company projects are migrating from WS above to JBoss, because many of the previous projects rely on WS, so the changes are great. I'm in charge of WebService's module changes recently. The new project was completely disconnected from WS, and there was no problem with Tomcat, but there was a lot of problems with JBoss.

When multiple JBoss services are started on one service, the ports may conflict. If you modify the default ports one by one, it will be complicated; for this reason, JBoss provides a unified method for managing multiple instances (servicebindingmanager), the basic idea is that JBoss provides a server port binding file-xxx-bindings.xml, it defines multiple ports m
The ejb3.0 application must run in JDK or later versions.The ejb3.0 application needs to run in the EJB container. The javaee Application Server contains the Web Container and EJB container.
The ejb3.0 application requires the following Java EE application servers:JBoss (4.2.x or later)WebLogic (version 10 or later)
Note: currently, Tomcat is only a Web Container and cannot run EJB applications.

Add another tag as shown below. This tag is JBoss-specific, and is used to register a message-driven bean with a JNDI-name, using the format "queue/name ".

This will generate the following deployment descriptors in JBoss. xml:
