XML4J to Xerces Version

September 22, 2010

I have always thought the fact that IBM packages in their websphere JRE libraries a re-packaging of several xml jars specifically Xerces and Xalan. They call it the XML4J jar (the file name will be xml.jar). You can check out the version of the XML4J which is associated with your IBM JRE by running the following

java  org.apache.xerces.impl.Version

That’s supposed to give you the Xerces version However that’s the XML4J version not the Xerces version. I was able to find on an IBM support forum (http://www.ibm.com/developerworks/forums/thread.jspa?messageID=13919023) which lists out the version mapping. I have place it below as well for folks to see as well.
