In Jboss EAP7 I have added cxf maven dependencies in pom.xml and excluded webservices subsystem in jboss-deployment-structure.xml since want to use my own version of cxf defined in pom.xml. But get below exception during server start up-

回答1:
For anyone else who is facing above issue. Here is the solution. Add below dependency in pom/classpath-
<dependency>
<groupId>javax.xml.ws</groupId>
<artifactId>jaxws-api</artifactId>
<version>2.2.9</version>
</dependency>
javax.xml.ws.Endpoint is available in JBoss modules jar. During deployment conflict arises since it's in a different module and you've removed webservices dependency so webapp classloader doesn't see it (I'm assuming classloader look up hierarchy is another issue here since this class is available as part of JDK, ideally JBoss should have honored JDK classpath).
回答2:
jboss-deployment-struture.xml should be as follows
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<exclude-subsystems>
<subsystem name="logging"/>
</exclude-subsystems>
<exclusions>
<module name="org.antlr"/>
<module name="org.hibernate"/>
</exclusions>
</deployment>
</jboss-deployment-structure>
回答3:
Your application is using spring and therefore, are you sure you have installed the spring custom module in EAP 7 and have a dependency included in jboss-deployment-struture.xml file ? so that the required class definition can be found ?
As a reference, you can refer to this link, Spring module in JBoss 7
Also, make sure jboss-deployment-structure.xml has a dependency on this module as below.
<module name="org.apache.cxf.impl" export="true">
<imports>
<include path="META-INF**"/>
<include path="META-INF/cxf**"/>
</imports>
<exports>
<include path="META-INF"/>
<include path="META-INF/cxf"/>
</exports>
</module>
