Websphere 4 exception

[shiva shankar]

Hi all, I am frequently getting this exception and I am not able to start my application server (Websphere 4.0 ) ..."Error occurred during startup
java.lang.IllegalAccessError: try to access field COM/ibm/db2/jdbc/app/DB2Driver.loaded from class COM/ibm/db2/jdbc/DB2BaseDataSource ".
Can anyone give me a solution for this. Even if I reinstall the application server after a few days I am getting this error again.

Shiva,
Were you ever able to solve this problem. I am having a similar problem when my application makes a request to an EJB. I am running WebSphere 4.1 sp3 going against DB2 sp7 on AIX. I see by your stack trace that you are also using DB2. By the exception I am getting, it looks like there is a problem trying to access a method setClosed() in DB2Connection class. I was able to decompile the DB2Connection class and look at the access modifier for setClosed(). The method is synchronized, so does this meaning there is some threading issue??? Here is the stack trace I get from WebSphere:
