could not find deserializer

[itrahulsoni]

HI,
All

Tools I have used: JBoss 4.0.5GA wstools shiped with this server
Ant 1.6.5

I am developing webservice using the wstools that is shiped with the {JBoss_home}/bin directory

I have created simple service that will make addition of two numbers I have created wstools-config.xml file and web.xml file and rest of the files are generated by wstools like jax-rpc_mapping.xml and webservices.xml and the .wsdl file now when I am developing method that return void that works fine for me and when I am developing the method that return any type means String or Int it will throw the error could not find deserializer for the resule where encoding type = null when I am trying to invoke service using client.


Please help me to come out of the Problem.

OK,

I suggest you to follow the following link:

http://jbws.dyndns.org/mediawiki/index.php?title=JAX-RPC_User_Guide

If you're a newbie to webservices try to consider using JAXWS based Webservices instead of JAX-RPC ones. JAXWS is the future, JAX-RPC is just a backward compatibility stuff. Here's the link to other usefull information:

I have refer that and done the simple rpc style endpoint example
and i came to the same problem as I have described earlier that when my method in the webservice return any types that means String or Int it will throw me the errors while I am doing same thing with the return type void then everything works fine.

So what can i do for that because i have to develop webservice that return the String.

Please help me stuck to this problem since long time.

Rahul

There's the example in our tests. See:

JBOSSWS_SVN_ROOT/stack/native/trunk/src/test/java/org/jboss/test/ws/jaxrpc/samples/rpcstyle/

and

JBOSSWS_SVN_ROOT/stack/native/trunk/src/test/resources/jaxrpc/samples/rpcstyle/

It returns String and it works

Richard refers to the sourse code on the SVN repository. Either checkout the sources from the repository http://jbws.dyndns.org/mediawiki/index.php?title=Subversion or download the src binaries.

Hi,

I have developed the same thing for that means I have developed example that you have stated but still get the error that if i am returning the void then it will works fine with my client but when I am developing the service that return the type Int than it will throws the error.

I have done some googles on that and found that any kind of mapping is required for that and I have also included one file that is ws4ee-deployment.xml is that any kind of thing we required for the mapping so when it will return the service can use the mapping for the deserialization

The Error i got is stated below:

localhost invokeMethod >>> org.apache.wsif.WSIFException: SOAPException: SOAP-ENV:ClientNo Deserializer found to deserialize a ':result' using encoding style 'null'.; nested exception is:
[SOAPException: faultCode=SOAP-ENV:Client; msg=No Deserializer found to deserialize a ':result' using encoding style 'null'.; targetException=java.lang.IllegalArgumentException: No Deserializer found to deserialize a ':result' using encoding style 'null'.]

at org.apache.wsif.providers.soap.apachesoap.WSIFOperation_ApacheSOAP.executeRequestResponseOperation(WSIFOperation_ApacheSOAP.java:575)


and My wsdl file is following:

<definitions name="MathService" targetNamespace="http://math.ws.jboss.org/"

xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"

xmlns:tns="http://math.ws.jboss.org/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

Thank you for your all replies,
