I'm trying to configure Tomcat to use a DB2ConnectionPoolDataSource, but I'm experiencing problems which appear to be related to configuration - more specifically the datasource I've defined in the server.xml file, and the datasource returned from the InitialContext within the code are different. I receive a "Cannot create JDBC driver of class 'COM.ibm.db2.jdbc.DB2ConnectionPoolDataSource' " exception
Maybe this situation is best described with code. In server.xml <Context path="/emsl" docBase="emsl" debug="0" reloadable="true" crossContext="true"> <Resource name="jdbc/emsltestds" auth="SERVLET" type ="javax.sql.DataSource"/> <ResourceParams name="jdbc/emsltestds"> <parameter> <name>user</name><value>username</value> </parameter> <parameter> <name>password</name><value>userpassword</value></parameter> <parameter> <name>driverClassName</name><value>COM.ibm.db2.jdbc.DB2ConnectionPoolDataSource</value> </parameter> <parameter> <name>driverName</name><value>jdbc:db2:rtmwasdb</value> </parameter> <parameter> <name>url</name><value>//9.17.41.96:50000</value> </parameter> </ResourceParams> </Context> In web.xml <resource-ref> <description>DB2 Connection</description> <res-ref-name>jdbc/emsltestds</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> the code in my servlet try { Context jndiCntx = new InitialContext(); out.println("new InitialContext<br>"); DataSource ds = (DataSource)jndiCntx.lookup ("java:comp/env/jdbc/emsltestds"); out.println("got a DataSource<br>"); out.println(ds.toString() + "<br>"); out.println( (ds instanceof org.apache.commons.dbcp.BasicDataSource) + "<br>"); out.println( (ds instanceof COM.ibm.db2.jdbc.DB2ConnectionPoolDataSource) + "<br>"); conn = ds.getConnection(); // exception is thrown here .... } catch (Exception e) { out.println("Problems: " + e.toString()); } and finally the end result viewed with a web browser.... new InitialContext got a DataSource org.apache.commons.dbcp.BasicDataSource@7200b4 true false Problems: java.sql.SQLException: Cannot create JDBC driver of class 'COM.ibm.db2.jdbc.DB2ConnectionPoolDataSource' for connect URL '//9.17.41.96:50000' What is weird to me is if you notice the debug statements, I echo out "ds.toString()" which gives me org.apache.commons.dbcp.BasicDataSource@some_memory_address. I think this might be where at least one of my problems reside. Seems to me this should be COM.ibm.db2.jdbc.DB2ConnectionPoolDataSource@some_memory_address - maybe I need additional information in the server.xml file?!?! Any ideas/pushes in the right direction are greatly appreciated. Thanks in advance.
