Hello,

I solve my problem by changing WSDL format for obtain a SOAP request format like this:

<add>
<int>1</int>
<int>2</int>
</add>


to replace :
<add>
<param0>1</param0>
<param1>2</param1>
</add>

Hello,

Now i have another problem ith the EJB Call.

My EJB have an add method with this signature :

Integer  add( Integer x, Integer y)

my SOAP request is like this :
<add>
<int>1</int>
<int>2</int>
</add>

but when bc-ejb  process the request, it try to call EJB method  "urn:add" with this error :

 Can't find method 'urn:add' in EJB interface : $Proxy19


Do you know i can define to not used URN naming?

[Olivier Fabre - EBM WebSourcing]

Hello gaetan,

It seems that the ejb-bc try to call the ejb with the full QNAME of the
operation ("urn:add" in your example). But it has to use only the local
part of the operation name ("add" in your example).

To resolve your problem we need some additional information :

- The stack trace of the error.

- If you use the quickstart version of Petals, you could use the Petals
Webconsole to trace the messages exchanged between the components, and
then try to extract full information about the incoming EJB-BC message
(like operation QName, message content...).
If you do it, please reply with this information.

Regards
Olivier

Hello,
