When I remove the factory line I now get: Cannot create resource instance
2010-01-25 15:56:06:*WARNING*Connection to jdbc/MySql:: connect Other
exception: Cannot create resource instance
2010-01-25 15:56:06:Driver=com.mysql.jdbc.Driver
The libraries are all in common\lib. The ones I have added since the 5.5
install are:
jsrweb (my Java code), mysql-connector-java-5.0.8-bin.jar,
naming-common.jar, naming-java.jar, mail.jar, and activation.jar.
I picked 5.5 because it is not getting active develpment, yet supports Java
1.5, and has all the features I need hoping to minimize incompatabilities.
My Java "connect" code reads: (indentation was lost when I copied)
private void connect(String dbName)
{
lastException = "OK";
try
{
// Class.forName("org.gjt.mm.mysql.Driver"); <---I changed this last night
hoping to fix problem.
sysout.display("Driver=com.mysql.jdbc.Driver");
Class.forName("com.mysql.jdbc.Driver");
}
catch (Exception E) {lastException=" Unable to load driver";
E.printStackTrace();
sysout.display(lastException);}
try
{
sql = "Connection to jdbc/MySql:";
Context myContext = new InitialContext();
Context envContext = (Context)myContext.lookup("java:comp/env");
javax.sql.DataSource ds =
(javax.sql.DataSource)envContext.lookup("jdbc/MySql");
conn = ds.getConnection();
stmt = conn.createStatement();
sql = "USE "+ dbName; // attempt to mymic jdbcConnect set for dbName!
stmt.execute(sql);
sysout.display("**"+sql + ": connection to jdbc/MySql established.");
}
catch (SQLException E)
{ lastException="*WARNING*"+sql+ ": connect SQL exception: "
+ E.getMessage();
sysout.display(lastException);
//System.exit(4);
}
catch(Exception eOther)
{ lastException="*WARNING*"+sql+ ": connect Other exception: "
+ eOther.getMessage();
sysout.display(lastException);
//System.exit(4);
}
}

Subject: Tomcat 5.5 org.apache.naming.ResourceRef cannot be cast to
javax.sql.DataSource
<Resource name="jdbc/MySql" auth="Container"
type="javax.sql.Datasource"
factory="org.apache.commons.dbcp.BasicDataSourceFactory"
The specified factory is for the standard Apache commons DBCP, not the one
bundled with Tomcat. You might try removing it and let the Tomcat DBCP
factory do its thing.
My jdbc driver jar is: mysql-connector-java-5.0.8-bin.jar
Where is the JDBC jar located?
Since you're upgrading, why not upgrade to 6.0.x? (5.5 is not getting
much in the way of active development these days.)
