I have recently learned a quick and lazy way to change the version of the JDK used to run JDeveloper 10g R3.

Once it's done, restart and you will by asked to locate the version of the JDK you want to use. It's another step to get going with JAVA on Vista. -ecco

The Key to this problem is to understand the relationship between the WSDL and the wire format, and to realize that the name of the wsdl:operation is not necessary present on the wire. Let's take an example to clarify this point. Here is a simple JAVA interface, that will be our samle code today: Figure 1.

If you are using Oracle Application Server 10.1.3.0, here is the explaination for the message and two ways out. The Exception: unexpected null value for literal data at oracle.j2ee.ws.common.util.exception.JAXRPCExceptionBase.<init>(JAXRPCExceptionBase.java:52) at oracle.j2ee.ws.common.encoding.SerializationException.<init>(SerializationException.java:26) ... The relevant schema: <complexType name="Customer"> <sequence> <element name="address" type="tns:Address"/> <element name="firstName" type="string"/> <element name="lastName" type="string"/> </sequence> </complexType> A sample code that will cause this exception: public void testServ() throw...
