JSP hanging when 9i database invoked through JSP

Question

Hi
I have just installed Oracle 9i DB on Win 2000 server. When I try to invoke a SQL from a jsp on the application server on the same machine, it hangs.
The jsp is able to connect to the Oracle 8i database on a different machine. We are having classes13.zip in the classpath.
Has somebody faced this problem before? Pl. help me out
Its urgent.
Thanks in advance
Ashish.

hi Vipul
Following is the file that we are using to connect to the database. The following file is invoked from the command prompt and it takes very long (8 minutes on the same machine) to connect to Oracle 9i. With JSP (tested on JRun and Oracle9iAS), we are never able to connect. The JSP and java file from command prompt both give instantaneous results even from a remote database if the DB is Oracle 8i.
Thanks
