Re: [Ikvm-developers] Class loading issue of com.sun.xml* classes

[Jeroen F. <je...@su...>]

Hi,

This fails because the class loader returned by getContextClassLoader (by default this is the system class loader) does not know how to load this class.

BTW, this is unrelated to your problem, but even in Java this is not the recommended way to load a class. At the very least you should use Class.forName("...", false, cl) instead of calling loadClass directly.

If you can change the code, change it to simply do Class.forName("...") and it will work (if this code ends up in the same assembly as the XWSSProcessorFactory2_0Impl class.

If you cannot change the code, you'll need to set the context class loader to a class loader that knows how to load XWSSProcessorFactory2_0Impl.

For more on class loading see https://sourceforge.net/apps/mediawiki/ikvm/index.php?title=ClassLoader

Jeroen
