Load my own Xalan implementation where an older Xalan is loaded to the parent classloader

Question

I\'m writing a plugin for a framework that loads my code as a child classloader

The problem is that that framework uses a certain Xerces version, that is not compatible

Answer 1

try doing:

ClassLoader oldContextClassLoader = Thread.currentThread().getContextClassLoader();
Thread.currentThread().setContextClassLoader(childClassLoader);
try{
    // do xml parsing
}finally{
    Thread.currentThread().setContextClassLoader(oldContextClassLoader);
}
