Hello, I am currently developping a web application on tomcat 4.1.12 under linux, with sun sdk 1.4.01.
I am using the JNDI resources together with jdbc pool from jakarta
(commons dbcp).
My web.xml file references my jdbc ressources, which are defined in my server.xml
file, in the Context element of my application.
When my application is deployed under the default service, everything works fine. I
get a connection from the pool when requesting a data source from my jndi context.
I want to deploy this application under an Apache 1.3 server running on the same host.
For this, i use a WARP connector (together with mod_webapp), as the example at the end
of the server.xml. The connection between apache and tomcat works perfectly (i can see
my files).
But, i can no more have access to JNDI resources (hence no connection to my database).
I tried multiple ways to perform this, putting the declaration of the pool in the
Context element of the application deployed under WARP connector, or putting it in the
GlobalNamingResources. No matter how i try, the connection pool pretends not to know
the class for my jdbc driver.
This is the exception and the beginning of the stack trace:
Cannot load JDBC driver class 'null' (class java.sql.SQLException: Cannot load JDBC
driver class 'null')
BasicDataSource.java: 529 => org.apache.commons.dbcp.BasicDataSource.createDataSource
BasicDataSource.java: 312 => org.apache.commons.dbcp.BasicDataSource.getConnection
And then here comes the place where i claim for a jdbc connection:
Context initCtx = new InitialContext() ;
Context envCtx = (Context) initCtx.lookup("java:comp/env") ;
ds = (DataSource) envCtx.lookup("jdbc/TEST") ;
// The exception is raised by this call (ds.getConnection())
// to the BasicDataSource.java: 312
Connection connection = ds.getConnection() ;
Does the jndi or common dbcp have problems with WARP connector ?
I join with this mail my server.xml as an attachment. I changed the names (database,
user, pwd), but the principle is here. The file is correct on my server (in case i
introduce a xml error while changing names). I tried multiple version of this file,
declaring only a standalone context (service on port 8080), only one context for
apache (using warp connector), or both, like in the file i join.
Please, can someone help me with this problem. I am struggling with this, and my
application should work as soon as possible.
