Re: Problem with Data Source Definition
I don't know the cause of this problem. I set up the datasource inforamtion in both Tomcat's server.xml and the application specific web.xml rather than in struts-config.xml, and I have no problem. The regarding part in the server.xml: Resource name=jdbc/LocalNesSQLServer scope=Shareable type=javax.sql.DataSource auth=Container description=The Nes SQLServer Database residing on machine, 192.168.8.136 /Resource ResourceParams name=jdbc/LocalNesSQLServer parameter namedriverClassName/name valuecom.microsoft.jdbc.sqlserver.SQLServerDriver/value /parameter parameter nameurl/name valuejdbc:microsoft:sqlserver://localhost:1433;databaseName=nes;SelectMeth od=cursor/value /parameter parameter nameusername/name valuenesuser/value /parameter parameter namepassword/name valuepassword/value /parameter !-- Maximum number of dB connections in pool.

Re: Problem with Data Source Definition
I've a problem with dbcp but it was different: I was declaring my ds in a tomcat config file but the .jar file (which contains the jdbc driver) was available only for my application (in WEB-INF/lib) and not for the Tomcat itself :-( Is your driver available in WEB-INF/lib ?
