> Key: AXIS-1297
> URL: http://nagoya.apache.org/jira/browse/AXIS-1297
> Project: Axis
> Type: Bug
> Versions: 1.1
> Environment: Axis 1.1; JBoss 3.2.3, possibly Tomcat 4.x. Have seen on Windows XP and Linux.
> Reporter: John G. Norman
>
> The jaxrpc.jar shipped with Axis 1.1 includes interfaces that belong to JAXP. They are:
> javax/xml/transform/dom/DOMSource.class
> javax/xml/transform/sax/SAXSource.class
> javax/xml/transform/Source.class
> javax/xml/transform/stream/StreamSource.class
> Because on some servers, namely JBoss, JAXP is loaded by a different classloader, class cast exceptions are produced when other Axis classes expect these classes to be loaded by the same classloader.
> (Note that it can be tricky on JBoss to alter the classloading mechanism for a particular .ear or .war, and impossible in some cases without access to the server setup.)
> This is a blocker for many applications on JBoss, especially ones that need to use a particular version of XML and also Axis. The presence of these JAXP interfaces in Axis's jaxrpc.jar creates a conflict.
> It seems very weird that the Axis jaxrpc.jar would include these interfaces, anyway: They don't belong there. A developer should be able to put in place his favored XML parser implementation.
> For what it's worth, I made my own version of Axis's jaxrpc.jar that simply omits these items, so that Axis just uses the JAXP items that are available as part of normal JBoss startup. It seems to eliminate the typical class cast exceptions.
