找不到rt.jar的类

Question

In JBOSS EAP 6 (AS 7):

I am making a call to Spring's WebServiceTemplate.marshalSendAndRecieve which in turn is having trouble finding a class that exisits in rt.jar

Caused by: java.lang.ClassNotFoundException: com.sun.org.apache.xerces.internal.dom.DocumentImpl

I do not understand how this can happen? Surely everything that is in rt.jar gets loaded up on startup?

Any ideas?

Thanks,

Kenny

Answer 1

Ok I found a solution (not sure if its the correct way, but it works).

I noticed by running java -verbose:class that only some of the classes in rt.jar were loaded and not the one I needed (com.sun.org.apache.xerces.internal.dom.DocumentImpl)

So in JBoss EAP 6 (As 7) there is a modules directory ($JBOSS_HOME/modules/) And under here there is sun/jdk/main/modules.xml

I added the following entries:

<path name="com/sun/org/apache/xerces/internal/dom"/>
<path name="com/sun/org/apache/xerces/internal/xni"/>
<path name="com/sun/org/apache/xerces/internal/jaxp"/>

(last 2 becuase of subsequent class not found exceptions after adding in dom)

As I said I'm not 100% sure if this is the correct way to do this. Any input is welcome!

Thanks,

Kenny
