I'm very new to MySQL, Tomcat, connection pooling, JSP, etc. and I've
been banging my head against a wall for two weeks trying to get a simple
program to connect to a MySQL database.

redeploy the new one through Tomcat Web Application Manager. Then restart

Greetings all,
I'm working with mysql-5.1.11-beta-linux-i686 set up using the NDB
cluster. I was wondering if there are any limitations or inefficiencies
if I was to use a connection pool to the mysql server(s) front-ending
the cluster? Several processes will make a request of our server and
Has anyone implemented connection pooling in C# .NET?

I don't hear you need to implement connection pooling. Maybe, but I think
you might still have errors under load, as you approach the maximum
connection count in the pool.

. It will
also wait for the first SELECT to finish!
So what constitutes a new client exactly? We use Perl and DBI to connect to MySQL.
Does this mean that everytime we connect to the DBase it is considered a new client?
If so , would some form of connection pooling/caching help reduce the lock delays
for the UPDATE to finish. It

Has anyone managed to setup Tomcat to use MySQL for database

Has anyone managed to setup Tomcat to use MySQL for database connection pooling? I've
found this document which gives information on it:
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html
However, when I try and run it I get messages about not being able
the right one...

I have configured WAS Express 5.0 to connect to MySql

As far as I can tell, this is a bug in WebSphere's connection pooling
classes, because getTypeMap() is not required to be implemented (by the
JDBC spec.
You can try returning an empty java.util.HashMap() from that method and
see if that makes your connection pool work. If so, I can add
sql, query ... just to make the filter happy.

Thank you so much for the quick reply.
Now I understand why the implementation of

On the other hand, you don't need to re-invent the wheel either. There
is a lot of open source connection pooling code out there. The one I'm
currently recommending (as it sees the most current development) is DBCP

Mark,
if you do not explicitly do
SET AUTOCOMMIT=0
then MySQL automatically calls COMMIT after every SQL statement.
Make that:
SET AUTOCOMMIT=1
