I use Tomcat to do JSP and I put the JAR file with my db drivers into
webapps/<context>/WEB-INF/lib directory and they are always found. No need
to alter any class paths.

Subject: [ClassPath] JSP, JDBC, and mm.MySql
Its getting late but I'm not having too much luck at getting a
sucessful
JSP / mysql connection. Given the error message below can someone explain
where I should be setting my class path and the actual mm.mysql files or the
entire jar file? I am using jdk1.3 with the latest apache on win2K pro.
My JSP page looks like and the error is below:
<html>
<head>
<title>Login</title>
</head>
<%@ page import="java.sql.*, java.io.*" %>
<%
// Step 1: registering the MySQL JDBC driver
try {
// The newInstance() call is a work around for some
// broken Java implementations
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
}
catch (Exception E) {
out.println("<br><br>some crap<br><br>Unable to load
driver.<br><br><br><br>");
E.printStackTrace(new PrintWriter(out));
}
%>
</html>
error:
