Problem starting up WAS v3.5 standard edition

I have successfully installed WAS v3.5 Standard Edition on Linux RedHat version 7.2, but I have problem starting up the server. When I type /opt/IBMWebAS/bin/./, I got the following error from the trace log.
[root@timecard bin]# tail -f ../logs/tracefile
at java.lang.Throwable.<init>(

FYI, my database used is PostgreSQL, not DB2. Do you think the problem is here with the admin.config file setting. I indeed tried modifying the admin.config file even though it is not an appropriate way to do so. I modified the dbUser, dbPassword, dbDriver, dbURL, and the classpath so that it knows where to find the jdbc driver file. BUT I failed to start the server again with the same message.
I know how to deal with this problem in WAS v4.0 Advanced Edition as I can start the admin console once finishing installed WAS4.0 (the console can be launched easily from the which pop up automatically).
Can anyone tell me how I can do resolve the start up problem in V3.5 Standard Edition?

I wonder if the prerequisites stated on the web site is accurate as I got PostgreSQL worked fine with WAS40 Advanced Edition although it didn't mention postgreSQL was supported.
Besides, I found out something that might be critical to the problem I am facing now. According to the installation guide, I need to install pdksh before calling the command ./ What I did was that I missed the pdksh part. Is it a MUST that I need to install pdksh before installing WAS V3.5?
Let's assume that this is true. How do I uninstall WAS V3.5? There is a directory named UnInst under /opt/IBMWebAS, however, there is no such thing call as mentioned on some of the .pdf I downloaded from IBM web sites.
As you know both WAS40 and WAS35, what is the difference between the two in terms of the installation steps (not the features of the two)? To me, with WAS40 Advanced Edition, the server can be started with just a click as the whole installation is GUI. With WAS35 Standard Edition, won't lead me to a GUI which I can do with just a click.
I agree. Here's the link:
