I'm having trouble connecting to MySQL using JNDI with Tomcat. I have
deleted my server.xml and started with a fresh copy. First, I made sure I
could connect to MySQL with a regular JDBC connection. Next, I added a
JDBC Realm using MySQL. That works fine. Finally, I added a JDBC resource
and tried to use it. That is when I get the error below.
The error I have, and have always had, even before the 4.1 detour, is the
following:
javax.naming.NamingException: Exception creating DataSource:
org.hsql.jdbcDriver

Why would Tomcat be looking for a Hypersonic SQL driver? I took a shot and
copied Hypersonic 1.61 hsqldb.jar to /common/lib, but when it had no effect
I removed it.
I'm currently running
Windows 2000
J2SE 1.4.0
J2SE 1.3.1
Tomcat 4.04
MySQL 4.0.2-Alpha
MySQL Connector 2.0.14. (I copied mysql-connector-java-2.0.14-bin.jar to
$TOMCAT_HOME/common/lib,)
I get the same error no matter what code I run. For example, Both code
blocks below result in the same error:
Context ctx = new InitialContext();
ctx.addToEnvironment(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.fscontext.RefFSContextFactory");
Connection conn = ds.getConnection();
if(ctx == null )
throw new Exception("Boom - No Context");
DataSource ds = (DataSource)ctx.lookup(
"java:comp/env/jdbc/TestDB"); <-- Blows up here
--- AND ---
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
if(envCtx == null )
throw new Exception("Boom - No Context");
DataSource ds =
(DataSource)envCtx.lookup("jdbc/TestDB"); <--- Blows up here
I added the following to the web.xml file:
<resource-ref id="ResourceRef_TestDB">
<description>DB Connection</description>
<res-ref-name>jdbc/TestDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

Any ideas?
