yanke commented on XMLBEANS-376:
--------------------------------

We had this problem on WLS 10.3 (weblogic running on jdk1.6) 

I manually removed from xmlbeans-2.3.0.jar 4 classes (org.w3c.dom.*) and published \
the new jar in our intranet maven repository with a different classifier: 

<groupId>org.apache.xmlbeans</groupId> 
<artifactId>xmlbeans</artifactId> 
<version>2.3.0</version> 
<classifier>java6</classifier> 

with this new jar our application works in both tomcat and Weblogic (with JDK6) 

What do you think of this approach? 
Had you implemented a special logic inside the org.w3c.dom classes that we will miss \
when using specific xmlbeans functionality? 

If our approach is fine, would you publish a similar jar (without org.w3c.dom \
classes) also in maven official repo? 

thanks for your feedbacks, 
Yanke
