No serializer found for class

asbin88 Jan 25, 2006 10:10 AM

Hi,
I got a problem with a serializer class not found by jboss.
This is a .Net Client trying to receive a complex object.
I can send complex objects so apparently the deserializer was created by wscompile, but I can not receive objects from jboss.
Is this a wscompile/net problem or what could be the problem?

Allways getting this error:

An unhandled exception of type 'System.InvalidOperationException' occurred in System.Web.Services.dll

Additional information: Client found response content type of 'text/html;charset=utf-8', but expected 'text/xml'.
The request failed with the error message:

I forgot to say that I'm using jboss4.0.3SP1 and the Complex UserDTO type doesn't contain any array's.
Thanks for your help :-)

Well because nobody answered to my last posts I try to describe the problem more detailed. Maybe somebody knows a solution.

I have a CMP Entity-Bean named UserBean containing some values like name, id, rights and so on , nothing special only Strings and Booleans.

After running wscompile with the documentliteral option I get a UserDTO_LiteralSerializer.java and some Class files among other things a UserDTO$ReadOnlyUserDTO.class.

After deploing the Wevservice I can access it with my .NET Client and can call methodes on a Session Bean called UserManager.

Everything works if I want to send a UserDTO object from Net to Jboss and I can create new Users in my database.

What I want to do next is call a methode like this UserDTO getUser(String id).

This doesn't work because JBoss cann't find a serializer for class or
g.mrbibjay.interfaces.UserDTO$ReadOnlyUserDTO. It cann't find it because its not there wscompile didn't create a UserDTO$ReadOnlyUserDTO_LiteralSerializer.

So what am I doing wrong?

Help appreciated ;-)

The *_LiteralSerializer is a JWSDP specific artifact and not needed in jboss. What you should look out for is the mapping of the schma type to the java class in jaxrpc-mapping.xml and whether this shows up correctly in the generated *.wsdd
