Top-Down Web Service Generation fails

[Former Member]

Hi all,

please excuse me if this is the wrong forum and redirect me to the correct one.

I'm trying to generate a web service Java skeleton from a WSDL file. Please find the WSDL at the end of the post. For the creating the skeleton I right-click the WSDL file in the Project Explorer and select "Web Services" > "Generate Java bean skeleton". The slider is set to "Develop service" and for the Configuration part I select an EJB project which I create prior to using the wizard. The respective Enterprise Application Project is selected automatically, similarily the "Server" (SAP Server) and "Web service runtime" (SAP Netweaver) are set up due to my default settings/preferences. No client is generated, and none of the checkbox options are chosen. For the following windows I leave the default settings and no collisions are found. But after clicking "Next" on the screen that would list collisions that should be resolved, the generation fails with the following error message: (Please let me know if I should post the full message as this is a shortened version)

IWAB0014E Unexpected exception occurred.

The WSDL file passes the WSDL validator without any errors. The following is taken from the "About" information of my NWDS installation:

SAP NetWeaver Developer Studio

SAP NetWeaver 7.1 SP05 PAT0000

Build id: 200802021401

I tried generating the web service using a default Eclipse installation, which works. All the same settings as above are chosen, however, the target server and libraries aren't the SAP runtime but instead Axis. The following is taken from the "About" information of the Eclipse version with which the skeleton generation suceeds:

Version: 3.3.2

Build id: M20080221-1800

As the generation works when using plain Eclipse and the WTP plug-in, I assume that the WSDL is fine. Is there a way to upgrade the plug-ins? Following is the version information for the "WTP Webservice UI Plug-In" for both NWDS and Eclipse:

NWDS: 1.1.103.v200802192030

Eclispe: 1.1.101.v200706121000

Please let me know what other pieces of information could help solving this problem. Thank you for your time in advance!

Cheers,

Felix

FYI

The problem seems to be related to importing WSDL files. When including the elements from bw-2.wsdl and brw-2.wsdl directly in the posted WSDL the generation succeeds. Nevertheless importing rw-2.wsdl works fine.
