I tried many times to get the connection between my web application and Derby and I received these error messages in the eclipse console:

INFO: Server startup in 3772 ms ERROR: Cannot load JDBC driver class 'org.apache.derby.jdbc.ClientDriver' ERROR: Cannot load JDBC driver class 'org.apache.derby.jdbc.ClientDriver' 11/02/2011 19:08:53 org.apache.catalina.core.StandardContext reload

My class and database definition is showed bellow:

// Obtain our environment naming context
javax.naming.Context initCtx = new InitialContext(); javax.naming.Context envCtx = (Context) initCtx.lookup("java:comp/env");

// Look up our data source by the name we gave it when we created it. // In this case that's "jdbc/customer". javax.sql.DataSource ds = (DataSource) envCtx.lookup("jdbc/customer");

conn = ds.getConnection();

And my web.xml and context are showed bellow.

in context.xml ...

and in the web.xml ...

DB Connection jdbc/customer javax.sql.DataSource Container

jdbc/customer javax.sql.DataSource

I'm using tomcat 6 with eclipse wtp (europa) in windows. And I already put derby.jar and derbclinet.jar inside of WEB_INF\lib directory ...

There are something that I can do to solve this issue?

Thanks!
