Failed to create delegate ERROR

[Former Member]

Hi All,

I am getting the following error after I import the web service model and binded it to the view.

Request for any clue to resolve this issue.

com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to create delegate for component com.abc.pct.xyz.CAObject. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)

Hi Mukesh,

I tried several times by rebuilding the project. it says "Caused by: java.lang.ClassNotFoundException" .

Any idea how to explicitly set the class path ?

Hi,

R u using any DC's in your project? Make sure about used DC's. If possible reassign them once again.

R u deploying application from DTR perspective? Try with Web Dynpro Application ( Deploy and Run).

Hi Venkatesan,

1. Remove the binded node from component controler and from the view.

2. Save the Project and rebuid and deployee.

3. Bind the node to the component controler and view

4. Save the project and execute it.

Kind Regards

Mukesh.

Hi All,

This problem is resolved after shorten the View Name Length. I noticed that the error was getting populated after binding the CC to that particular view.

Thanks for all your kind support.

Hi Nagaraj,

I am using SAP_NETWEAVER_2004S FULL JAVA EDITION which I downloaded from sdn.sap.com.

I never get this error for other projects. Why Iam getting for this project. Also that error says "java.lang.ClassNotFoundException" . Do I need to explicitly set class path. If yes tell me how ?

Expecting a reply.
