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

14 Views

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)

(5) Activated integrated ITS 640 in ECC5

When I try to access any ESS webdynpro iviews from the Portal, for eg the Address iview :

https://Portalhost.domain/webdynpro/dispatcher/sap.com/essusaddr/Per_Address_US

I received the following error :

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