Hi,
We had a similar problem when running on castor under WinRunner environment. When
castor loads persistent libraries it calls Class.getClassLoader(). Here is an
extraction from function's javadoc:
"Returns the class loader for the class. Some implementations may use null to
represent the bootstrap class loader. This method will return null in such
implementations if this class was loaded by the bootstrap class loader. "
I added the following to handle the issue
Instead of line in KeyGeneratorFactoryRegistry.java and
PersistenceFactoryRegistry.java :
cls = KeyGeneratorFactoryRegistry.class.getClassLoader().loadClass( prop );
I put the following:
cls = getClassLoader().loadClass( prop );
protected static ClassLoader getClassLoader()
{
ClassLoader cl = PersistenceFactoryRegistry.class.getClassLoader();
if(cl == null)
{
// if the class is loaded by the
// bootstrap class loader get
// the default one.
cl = ClassLoader.getSystemClassLoader();
}
return cl;
}
Hope this helps,
Alex

Might be a red herring, but Check your patch levels on Solaris with JDK1.4.
You need to be running nearly all the latest patches - or weird behaviour
ensues
