DataSource and JNDI problem at Tomcat 4+Apache

[Tuna Vardar <tu...@webzone.fi>]

Hello,

I got a datasource definition at server.xml and the web application gets
connection to DB by getting datasource object from JNDI. I defined the
<Resource> between <GlobalNamingResources> tags. And I defined
<ResourceLink> from <Context> definition.

This configuration works perfectly with Tomcat 4.1. I use MySQL 3.23 as
a database server.

But when application is plugged to Apache Web Server by using
org.apache.catalina.connector.warp.WarpConnector connector, I got
following exception:

Cannot load JDBC driver class 'null'
java.lang.NullPointerException

It seems like Apache + Tomcat 4 configuration doesn't get the DataSource
description and its parameters from server.xml.

MySQL drivers are placed both in TOMCAT_HOME/common/lib and web
application's WEB_INF/lib directory.

What can be the cause for the exception I mentioned above? Any comments?

Br,
tuna

I placed everything under a context in server.xml, but still same
problem existed.

I added connector to an existing install. And finally I used JK 1.3 AJP
connector. And now application works fine with Apache 1.3.

Sounds very similar to the issue I had when trying to move to 4.1.27. When I 
moved from 4.0.4 to 4.1.27 the exact same issue arose. If you put everything 
under a context it should be okay.

Have you simply added the connector to an existing install, or did you try a 
new install with the connector? Also, the warp connector is actually old - 
isn't the Apache connector for 4.1.X the AJP connector?

Peter
