Runtime Error: NoClassDefFoundError

Hi All,

My WebDynpro project compiles cleanly in NWDS 2.0.11 but I get a runtime error.

I looked up the forums and there are a lot of posts complaining about the same. It was suggested that possible mismatch between NWDS version and Application server Patch level could be one of the reasons. I use NWDS version 2.0.11 and WAS 6.40 SP11. No mismatch there.

Can somebody explain me this runtime error?

Error StackTrace:

com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to create delegate for view org.jabil.customer.ListProjects. (Hint: Is the corresponding DC deployed correctly? Does the DC contain the component?)

    Are you using an external jar? There was a bug in SP 11 where you had to set the the fact that your jar is used at run time and compile time separately. You had to set the run time link and then exit out fo that screen. You then had to go back in and set the second parameter.
