I have a j2ee app deployed on WebLogic 6.1 on HP-UX 11i. The app uses the java web services developers pack (JWSDP) version 1.2 to call webservices deployed elsewhere. The webservice calls work flawlessly when the app is deployed to WebLogic on Windows 2000 (my dev environment). However, on HP-UX I get the following error:
java.rmi.RemoteException: HTTP transport error: java.lang.UnsupportedOperationException: HttpURLConnection.writeRequests(1); nested exception is: HTTP transport error: java.lang.UnsupportedOperationException: HttpURLConnection.writeRequests(1)

Does anyone have experience running the JWSDP on HP-UX? Any ideas why I might be getting this exception?

Thanks.
