classloader problems

[Dave Dunkin <Da...@Attachmate.com>]

I'm having a problem with axis throwing a ClassNotFoundException when I try
to access a deployed service. It chokes on [Lservice1._RecordType; (see the
attached wsdl). I traced it down to the getLanguageSpecificType method in
WSDDTypeMapping.

    public Class getLanguageSpecificType()
        throws ClassNotFoundException
    {
        if (typeQName != null) {
            if
(!WSDDConstants.WSDD_JAVA.equals(typeQName.getNamespaceURI())) {
                throw new ClassNotFoundException(JavaUtils.
                             getMessage("badTypeNamespace00",
                                        typeQName.getNamespaceURI(),
                                        WSDDConstants.WSDD_JAVA));
            }
            String loadName =
JavaUtils.getLoadableClassName(typeQName.getLocalPart());
            ClassLoader cl = Thread.currentThread().getContextClassLoader();
            return cl.loadClass(loadName);
        }
        
        throw new
ClassNotFoundException(JavaUtils.getMessage("noTypeQName00"));
    }

Now if I replace these two lines:
            ClassLoader cl = Thread.currentThread().getContextClassLoader();
            return cl.loadClass(loadName);

with this:
            return Class.forName(loadName);

everything works. Why is the contex ClassLoader used instead of the default
ClassLoader?

Here's the full stack trace:
