Webdynpro application deployment issue.

Question

Hi Laydies/Gentlements,
When I try to deploy webdynpro application, it threw application deployment exception. Anyone can help me?
The message like below:
2010/11/11 下午 03:36:36 /userOut/deploy (com.sap.ide.eclipse.sdm.threading.DeployThreadManager) [Thread[Deploy Thread,5,main]] ERROR:

I copied the source from the other project to current new DC Project. But it's not deployed  successfully.
Thank you
Hope you can help me.

Answer 1

Hello,
There are two reasons for the Clusterwide exception:
1) Firstly, check whether all the referenced components (any used DCs) are already deployed on the server. If not, then first deploy those components and then try deploying the eform.ear again
2) If all the dependent components are already deployed, then the reason for this error is that there is already an .ear deployed on the J2EE server with the same application and/or component name. So, you must either:
a) Undeploy the previous application (having the same application name as the eform.ear application)
OR
b) Create a new application in the eform.ear project and rename the component. Renaming the component would require changing the name of the component in the implementation as well, wherever the component has been referenced. The newly created application must be mapped to this new component.
Then try re-deploying the eform.ear again.
Hope this helps. Do let me know if you need further help.
