Hi,
Just need to express my disgust at the reliability Websphere 4.0.3 AE!!! Its so brittle its unbelievable!!!
I'm about to reinstall this application server for the third time in 2 months - this time its giving me the following error:
java.lang.ClassFormatError: com/ibm/ejs/sm/beans/_DataSource_Stub (Illegal constant pool index)
... I won't bore you with the rest of the details. The API states that this occurs when the JVM attempts to read a class file and determines that the file is malformed or otherwise cannot be interpreted as a class file.
However, does anyone know why this could be occurring? And why I've never experienced this with any other code or application server?
Cheers,
Steve

Hi,
Just to rant a bit more!!!
I tried to reinstall WAS4.0 with DB2 as the respository - I didn't uninstall the DB2 as its a pain to configure. I expected that WAS4.0 would be able to reconnect to the existing DB2 - Oh how I was wrong!!!
As I reinstalled WAS4.0 I was alerted to the fact that the DB2 JDBC driver was not at the JDBC 2.0 level - despite the fact that I had done this when I initially installed Websphere. Can anyone tell me how, or more importantly, why DB2 would revert back to a lower JDBC level despite have worked for weeks. The only trigger seems to have been the uninstall of Websphere!!! Did/Does Websphere change the DB2 configuration as it was being uninstalled???
I then reset the DB2 JDBC level and reinstalled WAS again but got another error - again a ClassFormatError but this time it said that the java.lang.String class had an illegal signature!!!
Why is Websphere so difficult!!! :-{
Cheers,
Steve

I have gone thru DB2 pains in the past, IBM should totally remove the need of a database to hold WAS repository.They should also support session in memory replication in clustered env which they need to have a database.
I think with WAS 5.0 they are planning to remove database dependency for websphere repository
From the article at
http://www.e-promag.com/eparchive/index.cfm?fuseaction=viewarticle&ContentID=2145&websiteid=
"WAS V5 no longer requires a relational database management system (RDBMS) as the administrative repository for multiserver configurations. All editions now use XML files to store configuration information. IBM says this change is a response to market resistance to the requirement of an RDBMS just for the repository.

Just curious of the error you have got, are you sure you have upgraded your JDK along with WAS?
I ran into this issue once when I use SQLServer as Repository, and after clean up FP and reinstall FP3 it is gone(I do have error in FP3 installation at that time).
If you think it is really WAS issue, you can just open a PMR against IBM tech support. Or post it in IBM's newsgroup, there are IBM tech people moderate that newsgroup.
For WAS 5.0 information, you can find more on:

Don't get me started about those stupid light bulbs.
