it is possible that the problem stems from Tomcat itself. The reason i say
that, is because i have setup a dbcp connection (using Tomcat 4.1, jdk 1.4,
oracle on win2k), and i have managed to get it to work with a particular
application, but get the same Cannot load JDBC driver class 'null' when

but I make a mistake and use
Context path=/dBTest docBase=DBTest
debug=5 reloadable=true crossContext=true
**Notice the D vs d in the context path**
Then I get a Cannot load JDBC driver class 'null' error message
With the root context, where I had my problem
context
ctx lookup
gonna try a ds.getConnection
java.sql.SQLException: Cannot load JDBC driver class 'null'
at
org.apache.commons.dbcp.BasicDataSource.createDataSource(BasicDataSour
ce.java:529)
at
org.apache.commons.dbcp.BasicDataSource.getConnection(BasicDataSource.
java:312
Has anyone else experienced this
I have read a couple of posts that I found off google,
and basically what they are saying is non of the information in
the server.xml file is being passed to the Datasource or something of
that nature.
The suggested fix was to hardcode everything but that kind
But when I try to use it I get the following error:
java.lang.Exception: java.sql.SQLException: Cannot load
JDBC driver class 'null'
Tomcat changed by itself the server.xml with many things
like:
Context
className=org.apache.catalina.core.StandardContext
cachingAllowed=true
charsetMapperClass

Hello,
I created a DataSource(jdbc/SAA) through Tomcat
Hi all,
I have found a solution to this problem. Its by no means elegant but if you get as
desperate as I have got then you may wish to do the same.
It appears that none of the information that you specify in your server.xml gets
through to the actual dbcp stuff, don't ask me why. So what I

Hi,
I get the error org.apache.jasper.JasperException: Cannot load JDBC driver
class 'null'.
What is this and how can I proceed from here? I have Tomcat 4.1.12, JDK1.4.1
installed and have DBCP 1.0, Pool 1.0, Collections 2.0, and Oracle's jdbc
driver classes12.jar(classes12.zip renamed to .jar
);
Hope this helps.

Roberto,
How are you instantiating your datasource?
You need something like:
