           Summary: AJP12 support broken ; loses query string
           Product: Tomcat 3
           Version: 3.3.2 Final
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: major
          Priority: P2
         Component: Connectors
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: renaud+jakarta@waldura.com


I must be the only person still using this thing, because it just blew up in my 
face in a big way. Apparently all query strings get dropped by Tomcat 332 when 
using the AJP12 protocol. (It works with Tomcat 331a. It works with AJP13.)

Environment:
Windows XP
Apache 1.3.33
mod_jk 1.2.6
Tomcat 3.3.2
Sun JDK 1.4.2

A "Test" servlet (included below) fails to print any values (no request 
parameters) when accessed over AJP12. Same servlet works with AJP12 on Tomcat 
331a. Also works with AJP13 on Tomcat 332.

To reproduce, setup Tomcat 332 with only the Ajp12Connector enabled. 
Setup Apache+mod_jk with one ajp12 worker. Access the servlet below with query 
string parameters.



public class Test extends HttpServlet
{
    protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1)
            throws ServletException, IOException
    {
        printParams(arg0, arg1);
    }
    
    protected void doPost(HttpServletRequest arg0, HttpServletResponse arg1)
            throws ServletException, IOException
    {
        printParams(arg0, arg1);
    }
    
    private void printParams(HttpServletRequest request, HttpServletResponse 
response) throws IOException
    {
        response.setContentType("text/html");
        response.getWriter().println("<html><body>");
        
        for (Enumeration e = request.getParameterNames(); e.hasMoreElements(); )
        {
            String name = (String) e.nextElement();
            response.getWriter().println("<p>" + name + " = ");
            response.getWriter().println(request.getParameter(name));
        }
        
        response.getWriter().println("</html>");        
    }
}
