Since I didn't get a response the first time round, and I CAN'T believe
that nobody has ever run into this before, and I can't find what I'm
looking for in the FAQ or the archive, and the doc. for tomcat4 seems to
be pretty much non-existent, and the notes with mm.mysql don't help,
I'll ask again...
I'm running tomcat 4.0.3 on debian woody with apache and mysql on the
same box. I can connect to mysql from another machine via tcp/ip on
port 3306, and from perl and php4 scripts.
When I try this code under tomcat, i get an error about 'can't find a
mysql server on port 3306'

but equivalent code (below) works just fine with pure java...
%<--------------------------------------------------------------------
import java.sql.*;
class HelloWorldApp {
public static void main(String[] args) throws java.sql.SQLException{
Connection conn = null;
Statement st = null;
ResultSet rs = null;
try
{
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
conn =
DriverManager.getConnection("jdbc:mysql://localhost/cartapp?user=root");
st = conn.createStatement();
rs = st.executeQuery("select * from employees");
while (rs.next()) {
System.out.println(rs.getString("lname_txt"));
}
}
catch (Exception ex)
{
ex.printStackTrace();
}
finally
{
if( rs != null) rs.close();
if( st != null) st.close();
if( conn != null) conn.close();
}
System.out.println("Hello World!"); // Display "Hello World!"
}
}

Has anyone had any similar issues, and can point me in the right
direction?
