Thanks a lot for your response!! I did come across this javadoc before, but unfortunately it does not have the WAS packages I need - the classes I need are in packages like com.ibm.websphere.runtime, com.ibm.ws.runtime, com.ibm.ejs.sm.beans (these packages are in runtime.jar, repository.jar, ws-base-config.jar, etc). The ones listed on this site deal mostly with web services support and http-related function.
If you know of any other sites, please let me know.
Thanks again for your help!!
