Problem: EJB calling a SOAP Service

Question

H� there!
I've got a remote Service (perl) and in a given moment I need to make a call from my stateless EJB.
For testing purposes I first made a set of classes and a test application. The calling works.
Then I extended my EJB, making the same call that my test application did. Then I get the following error:
Unexpected Error:
java.lang.IllegalAccessError: tried to access class javax.xml.rpc.FactoryFinder$ConfigurationError from class javax.xml.rpc.ServiceFactory
at javax.xml.rpc.ServiceFactory.newInstance(ServiceFactory.java:102)
Can enybody please help me?
NOTES:
- JBoss 3.2.2
- j2sdk 1.4.2 (my test application runs on j2ee 1.4.2)
- Axis 1.1
Regards!

Answer 1

I did it (wsdl2java).
But I am working with jaxrpc.jar and axis.jar.
What my EJB does is:
java.xl.rpcCall call;
try {
    java.xl.rpc.ServiceFactory serviceFactory = java.xl.rpcServiceFactory.newInstance();
    Service service = serviceFactory.createService(new QName("", "hello"));
    QName qName = new QName("http://www.w3.org/2001/XMLSchema", "Array");
    TypeMapping service.getTypeMappingRegistry().getDefaultTypeMapping();
    typeMapping.register(ArrayList.class, qName,
                        new ArraySerializerFactory(),
                        new ArrayDeserializerFactory());
    call = service.createCall();
    } catch (ServiceException e) {
        cat.error(e.printStackTrace());
    try {
        call.setTargetEndpointAddress("http:/localhost:81");
    } catch (JAXRPCException e) {
        cat.error(e.printStackTrace());
    call.setProperty(Call.SESSION_MAINTAIN_PROPERTY, Boolean.TRUE);
    call.setProperty(Call.SOAPACTION_USE_PROPERTY, Boolean.TRUE);
    call.setOperationName(new QName("", "hello"));
    try {
        return call.invoke(new Object[]{});
    } catch (RemoteException e1) {
        cat.error(e.printStackTrace());
    }Now I have another error which varies, it's quite disturbing me.
It goes from 'NoClassDefFound' to 'Linkage' errors...
Unexpected Error:
java.lang.NoClassDefFoundError: javax/xml/rpc/encoding/TypeMapping
and
Unexpected Error:
java.lang.LinkageError: loader constraints violated when linking javax/xml/rpc/encoding/SerializerFactory class
I get similar errors if I force the serviceFactory to be an instance of org.apache.axis.client.ServiceFactory.
Apparently I cannot make such remote calls within an only thread (?)
