I had a solution manager installation which I used to generate the key that was used for the Netweaver java 2004s Netweaver installation. to get the key, I used the SMSY transaction using the ABAP gui to the solution manager.
Not sure if I also had the SID for the solution manager as J2e but the SID of java stack is J2E.
So until I installed the Java Stack I was able to use the client tool to login to run my transaction
Now once my java stack is running, I tried to use the client GUI to login to the SOlution manager but no luck. Is it because the SID of the solution manager and the J2E are of the same name.
