JDBC classe file not found
I have a problem with my setup. The jdbc class file is not being
found when I start the tomcat server. I created test.jsp which
looks like this:
<%
// Check that the DB2Driver class is available
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver");
out.println("The test is complete, your JDBC driver is now setup");
%>
When executed under tomcat, it gives me lots of errors. I will append the error
file to this message since it is very long.
My setup is as follows:
Red Hat Linux 8.0
Tomcat 4.1
IBM DB2 UDB 8.0
I'm also running Apache HTTPD 2.0.44, mod_ssl/2.0.44, OpenSSL/0.9.6b, and
mod_jk/1.2.2 but none of these apply here (I think...)
I have searched the web for every combination of jdbc, db2 and tomcat I can think
of with no results.
I copied the file /opt/IBM/db2/V8.1/java/db2java.zip into the directory
/var/tomcat4/common/lib and renamed it to db2java.jar. I understand
that is all that is necessary to make it available to tomcat. It still
doesn't work.
Any ideas?
Here is the errors I get when I execute test.jsp on my tomcat server
"http://localhost:8080/test.jsp"
HTTP Status 500 -
