Hi Folks,
After implementing ESS/MSS2005 business package and install all needed pre configs (system connectors, JCO...) we still get on all webdynpros blank/white screens without error messages. If we add to the portal user we use with the ESS/MSS test (also has the right ESS/HR settings in the back-end) also the J2ee_admin Role in the SAP or the Super Administration Role in the Portal UME, the webdynpros works fine !
What missing rights we must add / change ??
Also we grant the rights for the needed system connectors to this user (group).
Thanks and regards
Mario
PS: our settings
Install new NW2004s as UT EP on Java and ABAP (used for UME) stack
Upgrade to SP6 for Java and ABAP NW2004s
Install MSS/ESS2005 (SP02) on same WAS like the EP
Maintain System and JCO settings
Create User in HR-backend system and Portal
Assign ESS/MSS role in the Portal
Blank webdynpro pages in ESS2005 on EP7 /NW2004s
