hi friends

When i try to connect to MYSQL in tomcat project, i can't connect that.The same program run fine without tomcat project.

Please help me

Code is
Connection conn = null;
String userName = "root";
String password = "rootpwd";
String url = "jdbc:mysql://localhost/test";
Class.forName ("com.mysql.jdbc.Driver").newInstance ();
conn = DriverManager.getConnection (url, userName, password);

This code is working fine without tomcat

i can't connect that.

What does this mean? Have you checked the Tomcat logs files if there are any error messages? If so, which ones?

Have you put the DB driver jar file into WEB-INF/lib directory of the web application you're running this code in? Remember that Tomcat doesn't use the standard system classpath.

First of all thank you for your replay

The problem is at the line
Class.forName ("com.mysql.jdbc.Driver").newInstance ();
conn = DriverManager.getConnection (url, userName, password);
where connection can't establish...I copied the connector
mysql-connector-java-5.0.8 into lib folder..Yet the prob persist

You still haven't told us WHAT the problem is - post the complete error message and stack trace.

Have you restarted the web app after copying the jar file?

You should remove the ".newInstance()" method call by the way. It's not needed.
