RE: WSDL descriptors

Title: RE: WSDL descriptors

Let me decribe it more deeply.

 

I have a SOAP server Apache SOAP 2.2, and a SOAP service. Service has 1 method:

public void uploadFile(javax.activation.DataHandler dh)

This method expects a DataHandler as parameter, that is, it expects an empty SOAP envelope with attachment (Apache SOAP will process this attachment and pass it to the method as a DataHandler).

 

Now I need to create a WSDL file that would decribe this service.

 

Suppose I want to use either GLUE java2wsdl or similar tool from IBM WSTK. This tool creates huge "type" structure for this single DataHandler object instead of simply including <mime:multipartRelated> binding into binding operation. This structure is very complex since it reflects the entire guts of DataHandler class. Even worse, the client who will call my service using this WSDL, will send out data as a complex structure inside the envelope, instead of sending out an empty envelope with outside attachment. Such invocation will fail since service expects attachment.

Invocation of service which accepts nothing and returns a DataHandler will also fail for the same reason.

 

As you can see, command-line WSDL generating utilities are useless here, I have to use raw WSDL API or even compose WSDL documents from scratch. And I wonder if anybody else has expirienced such a problem and if they could share their thoughts with SOAP community.

 

Best regrads,

 

Alex

hi alex,

 

GLUE has exactly what you're looking for, with full support for SOAP attachments

and bidirectional translation between java methods and WSDL using the wsdl2java

and java2wsdl utilities.

 

cheers,

graham

But there is no way to create an interface that would indicate some method will produce an attachment, is there?
Therefore, there is no way to create such WSDL descriptor from an interface, using existing generators found in toolkits like WSTK 2.41 etc.

Please correct me if I'm wrong.

You can use the web developers toolkit from IBM
wstk2.4
to create the wsdl from an interface.
