Java 链接错误 JAX-WS

Question

I am getting this Error while Trying to use WebServices. I googled for it and found that it occurs because different versions of same class files maybe present or some conflict occurs. I tried giving an endorsed Directory path while running Web Application, still no luck. The environment I am using is JDK 1.6.0.20 and JBoss 5.0.:

java.lang.LinkageError: loader constraint violation: when resolving method "javax.xml.ws.Service.<init>(Ljava/net/URL;Ljavax/xml/namespace/QName;)V" the class loader (instance of org/jboss/classloader/spi/base/BaseClassLoader) of the current class, com/abc/amservice/AMService, and the class loader (instance of <bootloader>) for resolved class, javax/xml/ws/Service, have different Class objects for the type javax/xml/namespace/QName used in the signature

Would appreciate any help. Thanks

Answer 1

A solution can be found in this question .

In short: make sure that you do not deploy another javax.xml.namespace.* package, rely on the one that is shipped with Java 6

Answer 2

There are two options that can help you:

1 - Change Jboss version at runtime. Download the Jboss again, your version can be cracked, it's very common. So set your Jboss runtime in Eclipse according your installation like as: "C:\jboss-eap-5.1\jboss-as".

OR

2 - Just remove the lib wsdl4j.jar at build path, if viable in your case.
