500 Internal Server Error while connecting JSP with Oracle

Question

Hello Friends,
We Have installed Oracle Applications 11i in our orgaization which run on HP-UX 11.11 (HP Unix). I have created a JSP file in which I am trying to connect the database using OracleConnectionCacheImpl Class File in oracle.jdbc.pool directory. But it shows an error message as:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
I have also installed Oracle HTTP Server on my personal machine at which this code runs perfectly only the error comes when i try to connect oracle from Oracle HTTP Server installed on our HP Unix Server.
the path for pool package is:
/appltest/apps/prodora/iAS/oem_webstage/oracle/jdbc/pool
the location of JSP file is:
/appltest/apps/prodcomn/portal/TEST_test/test
What I think is I have to play with the CLASSPATh entries, but dont know how. Please help me in solving this issue...
For your reference the JSP code is:
<%@ page import="java.sql.*, javax.sql.*, oracle.jdbc.pool.*" %>
<jsp:useBean id="ods" class="oracle.jdbc.pool.OracleConnectionCacheImpl" scope="session" />
<%
try
ods.setURL("jdbc:oracle:thin:@test:1546:test");
ods.setUser("kpm_hr");
ods.setPassword("kpm_hr");
Connection conn = ods.getConnection();
Statement stmt = conn.createStatement();
Resultset rset = stmt.executeQuery("select first_name,last_name from kpm_hr.kpm_hr_emp_mst where empcode='P0580'");
rset.next();
out.println(rset.getString(1)+" "+rset.getString(2);
catch(SQLException e)
out.println(e);
} Thanks in adavnce,

Just to verify, which relevant log files have you found?
catch(SQLException e) {
out.println(e);
} Have you search the console log file?
A quick observation reveals that your jsp is just a standalone java program executed inside jsp. Suppose you just run it as a standalone program. Any error then?
Another way going forward is to install oc4j standalone of the same version. It is very easy to install: just download the oc4j-extended.zip and unzip it and run "java -jar oc4j.jar". Put you jsp inside j2ee/home/default-web-app and run. You should see relevant log messages in j2ee/home/log/server.log and j2ee/home/application-deployments/yourApp/application.log.
You should have Jdeveloper of some appropriate version installed. If you have not, install one. It might be not a little bit high learning curve at first, but the rewards are quick and amazing, especially since jdev 10.1.3. (I am speaking from my experience.) Try it with Jdeveloper.
