'i A$ay* Than9 you for the great article and a time saver. I have a problem while creating proxy using wsdl. There are some errors after I clic9 complete but no details on the error. I have managed to successfully create the proxy classes in -clipse for a 4ava application using the same lin9 as below which is also the one I use for ABAP. http3==devH.axeda.com=webservices=services=AlarmService0wsdl I even tried to download the same and load as a local file. Is there any reason why this file is not acceptable in SAP but in -clipse. Is there a setting in SAP to ignore the validation as in -clipse0 If it is not too much trouble could you please try to create proxy for this and see what could be wrong. Is there a way to validate the file and a way to find and fix the error if there is any. Please help me point towards the right direction. Than9 you for your time. With Nind ;egards* Sudharshan ;-P!<
