[jboss-user] [Installation, Configuration & DEPLOYMENT] - Re: ClassCastException due to Xerces conflict during app dep

[rodos77]

Ok, I've created 2 patches for swapping out the context classloader. One for a class in the jbossweb project and one for a class in the JBossXB project. Either patch, when applied to the corresponding project, resolves the issue. You can now decide in which project it is more appropriate to fix this issue and apply the patch to the corresponding source repository to resolve this once and for all.

JBossXB patch:

  | +          Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader());
  | +

  | +          finally
  | +          {
  | +             Thread.currentThread().setContextClassLoader(oldCl);
  | +          }
  |   
  |            JBossXBParser parser = unmarshaller.getParser();
  |            if(validation != null)
