WSDL2Java Error

I'm currently running Apache Tomcat 4.1 with Axis 1.2.
I am not able to generate Client side code using WSDL2Java. I am getting this error:

java.io.IOException: Type {http://util.java}Enumeration is referenced but not defined.
at org.apache.axis.wsdl.symbolTable.SymbolTable.checkForUndefined(SymbolTable.java:665)
at org.apache.axis.wsdl.symbolTable.SymbolTable.add(SymbolTable.java:545)

at org.apache.axis.wsdl.gen.Parser$WSDLRunnable.run(Parser.java:361)
at java.lang.Thread.run(Thread.java:534)

I'm using complex objects between server and client.

Thanks!

first step is to validate your wsdl using any wsdl validators. This can show any problems with your wsdl.

Thank you RR Kumaran for the answer

The wsdl was generate by Axis 1.2.
I've tried to validate it with XMLSpy 2005.

" Cannot resolve declaration or definition 'Enumeration' in namespace 'http://util.java' ".

How can I resolve the problem?

Thanks again

You've referenced a 'thing' (of some type, I can't tell from the error message alone) named 'Enumeration' (in XML Namespace 'http://util.java'), but no definition could be found.

It's probably a type or element in an XML Schema, in which case you either need to import the schema correctly, or add the definition if it's missing.

If you can't work it out, post your schema and perhaps someone can help.

Here's the revelant part of the wsdls file.

Now I'm seeing a warning from axis :

- The class java.util.Enumeration is defined in a java or javax package and cannot be converted into
an xml schema type. An xml schema anyType will be used to define this class in the wsdl file.

What does it mean ?

The error after launch wsdl2tojava command remains:

java.io.IOException: Type {http://util.java}Enumeration is referenced but not defined.

OK, you've imported namespace "http://util.java" and associated it with namespace identifier 'tns3'. You've then referred to a type (presumably) defined by that namespace in lines like these:

However, you aren't providing a schema for namespace "http://util.java", so wsdl2java is complaining. AFAIK, you either need to add an xsi:schemalocation, or (and I find this easier with Axis) rewrite the current schema to not refer to an external one.

If you're not familiar with XML schemas, namespaces and the idea of importing schemas, you really need to learn these concepts before you can fix this problem.

By the way, did you write this schema/WSDL yourself, or generate it with a tool?

-Tim

The wsdl file was generated by Axis.

I have used Axis just in order not to have to learn these concepts.
But now, I think I'll learn them.

Thanks for now...

Ciao.

That was the way I learned too - initially I didn't know the messy details of XML Schema, WSDL, SOAP etc, but in the end I had to learn them to be able to identify and resolve bugs and problems.

Good luck!
