I was trying to install java components in ECC 5.0 IDES Server. it showing an error " This Installation requires an SAP J2EE Engine version 6.30 or higher"
and then i gave NEXT then it gave another error message " No instance found for the central instance. Check your file system. Install Web AS 6.30 and restart this deployment afterwards".
Kindly let me know how to find which version of Web AS now i am using and how to upgrade to higher version.
