Yep, this looks like exactly the problem I fixed.  Let us know if the current CVS helps, Dave!

 

Thanks,

Dave,

 

Glen just submitted something. It may as well fix your situation. You've got an array. Try next nightly build.

Yes, the class is available in the WEB-INF/classes directory, not in the system classpath.

Dave,

Are you sure the class it is trying to load (for a _RecordType type specified in WSDL) is available for a deployed Axis web app? That is, is it in WEB-INF/classes or in WEB-INF/lib?

Axis is inheriting the servlet classloader provided by the container. That's the guy that cannot load the class. It won't rely on the system CLASSPATH for security reasons. You'd have to provide it under a web app. The other approach is to define your classloader and jump arround Axis with it :).

Subject: classloader problems

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:
