Unable to connect to Sybase 11.9.2 server -Help please

[Kr...@HUD.GOV]

Hello Everyone,

I am trying to connect to sybase 11.9.2 database server. Has anyone
encountered this error. Your help on this will be greatly appreciated.

I have created a datasource in Tomcat 4.1.18.
I have the jconn2.jar file in webapps/ROOT/WEB_INF/classes/jconn2.jar
I have the jconn2.jar file in c:/tomcat4/commons/lib/jconn2.jar

However I get this error.

java.sql.SQLException: Cannot load JDBC driver class 'null'
      at
org.apache.commons.dbcp.BasicDataSource.createDataSource(BasicDataSource.java:529)
      at

      at SecurityCheckServlet.getConnection(SecurityCheckServlet.java:83)
      at SecurityCheckServlet.doGet(SecurityCheckServlet.java:37)

I have the following entries in the server.xml
