The attachments in my previous message got mangled. Sorry, I'm a newbie. Here is the relevant portion of the server.xml file (the formatting in this will probably get mangled too):
.. <DefaultContext> <Resource name="jdbc/WroxTC5" auth="Container" type="javax.sql.DataSource"/> <ResourceParams name="jdbc/WroxTC5"> <parameter><name>driverClassName</name><value>com.mysql.jdbc.Driver</value></parameter> <parameter><name>url</name><value>jdbc:mysql://localhost/wroxtomcat</value></parameter> <parameter><name>username</name><value>*****</value></parameter> <parameter><name>password</name><value>*****</value></parameter> <parameter><name>maxActive</name><value>20</value></parameter> <parameter><name>maxIdle</name><value>30000</value></parameter> <parameter><name>maxWait</name><value>100</value></parameter> <parameter><name>factory</name><value>org.apache.commons.dbcp.BasicDataSourceFactory</value></parameter> </ResourceParams> </DefaultContext> </Host> </Engine> </Service> </Server> And here is the relevant portion of the web.xml file: .. <resource-ref> <res-ref-name>jdbc/WroxTC5</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> </web-app> The code in the jsp that generates the exception is line 14 of the following snippet: .. 11: <% 12: InitialContext initCtx = new InitialContext(); 13: if( initCtx != null ) { 14: DataSource ds = (DataSource) initCtx.lookup("java:comp/env/jdbc/WroxTC5"); 15: Connection conn = ds.getConnection(); 16: Statement stmt = conn.createStatement(); 17: ResultSet rset = stmt.executeQuery("select * from employee;"); .. As you can see, I'm just trying to get an example working. Thanks again for any help, Kevin Quoting Kevin Hart <[EMAIL PROTECTED]>: > Hello, > > I'm trying to get a jsp to access a mysql database.
