J2EE Struts - Database connection failed - help???:(

Question

Hello,
I have built a little web application and it works without any problems. In the next step I tried to add a database connection but I have already worked on it for at least one day and I could not fix the problem with the database connection.
I downloaded the MySQL Server 5.0 and installed it, furthermore I have downloaded the jdbc driver mysql-connector-java-3.1.11.zip and extracted it to the MySQL Server 5.0 directory. Furthermore I have added under system settings - system - etended - system variables the whole path to the driver -> C:\Programme\MySQL\MySQL Server 5.0\mysql-connector-java-3.1.11\mysql-connector-java-3.1.11-bin.jar to the CLASSPATH systemvariable.
Then I have startet the SQL Server 5.0 with mysqld --console from the command line.
Furthermore I have added under Project-Properties-Java Build Path - Libraries - Add External JARs in Eclipse the mysql-connector-java-3.1.11-bin.jar to my Struts WebProject.
To test the whole thing I have added to the existing test-database from mysql a table named owner and wanted to test the database connection in the Action-class with the following statements - I quote the whole execute method of the OwnerAction class:
public ActionForward execute(
                 ActionMapping mapping,
                 ActionForm form,
                 HttpServletRequest request,
                 HttpServletResponse response)
                 throws Exception {
               OwnerForm ownerForm = (OwnerForm) form;
               String greet = ownerForm.getGreet();
               String name = ownerForm.getName();
               request.setAttribute("name", name);
               request.setAttribute("greet", greet);
               String address = ownerForm.getAddress();
               String email = ownerForm.getEmail();
               int tel = ownerForm.getTel();
               Connection conn = null;
               Statement stmt = null;
               ResultSet rs = null;
               DriverManager.registerDriver(new org.gjt.mm.mysql.Driver());
               conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/test","root","sa");
               try {
                     //conn = dataSource.getConnection();
                     stmt = conn.createStatement();
                     int id = 0;
                     rs = stmt.executeQuery("select max(id) as counter from owner");
                     while(rs.next()){
                        id = rs.getInt("counter");
                     id += 1;
                     stmt.executeUpdate("insert into owner values("+id+", '"+greet+"', '"+name+"', '"+email+"', '"+address+"', "+tel+")");
                     rs.close();
                     stmt.close();
                     conn.close();
                  catch(SQLException e){
                     throw new SQLException("database error");
                  // Forward control to the specified success target
                  return (mapping.findForward("success"));
      }But when I execute the WebApplication and the Action will be called the following error message appears in the browser:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception

     javax.servlet.http.HttpServlet.service(HttpServlet.java:810)
     org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81)
note The full stack trace of the root cause is available in the Apache Tomcat/5.5 logs.
It must depend with anything that the driver was not found but I have defined it in the CLASSPATH variable and added it to the Web-Project in eclispe.
Has anybody an idea what I have else made wrong or have forgotten??:(:(:(
thanks in advance

Answer 1

One thing I have forgotten - I have also copied the mysql-connector-java-3.1.11-bin.jar in the WebRoot\WEB-INF\lib directory of my EasyStruts WebApplication.
Can anything else be wrong??:(:((
