'java.lang.NoClassDefFoundError' when displaying ESS webdynpro iviews

[Former Member]

Hi,

We are running ECC5 backend & EP6 SP9. I have done the following :

(1) Applied via SDM the XSS components & ESS 60.2 Business Package in EP6

(2) Configured SLD

(3) Create/Maintain necessary Jco Destinations

(4) Create necessary System landscape (SAP_Webdynpro_XSS and etc)

When I try to access any ESS webdynpro iviews from the Portal, i'm getting the following error message:-

java.lang.NoClassDefFoundError: com/sap/tc/webdynpro/progmodel/api/IWDEventId

Hello Tommy,

Yes i've resolved it and now everything is running fine. The cause of the error is that the WebDynpro runtime is newer than the J2EE runtime.

So we patched the Portal to SP13(dont patch it to SP12 as SP12 has lot of issues with ESS iViews) and then patched the webdynpro also to SP13. Everything will be fine on SP13.

Please reward points if you find this helpful.
