I have a web (set to compile with 1.4 SDK) project with a test servlet that has xdoclet web.servlet tags, but I can not get xdoclet to modify my web.xml. I am concerned that I dont have the xdoclet settings right. I cant get xdoclet tag code completion to work either.

My tags:

* @web.servlet name = “checksess”
* display-name = “Check Session”
* load-on-startup = “1”
* @web.servlet-mapping url-pattern = “/chksess/*”

WinXP SP1

MyEclipse Version: 3.9.210, Build id: 20050627-4.0-Milestone-2

Where is the encoding issue now?

Ok…so I stumbled across getting the Standard Web settings for ceating the web.xml, but it now fails with the stack trace:

Jimmy,
I’m sorry we missed this post, sometimes a few slip by.

What locale is windows set to? This is an sun.io exception which makes me think it’s a JDK bug, try and upgrade to 1.5.0_04 that just came out to see if that helps.

I will try this as soon as my client gives me the right to load the software.

I just installed Sun JDK 1.5.0.04 and I start eclipse with the following bat:

SETLOCAL

SET CLASSPATH=C:\jdk-1_5_0_04\jre\lib\rt.jar;

SET PATH=C:\jdk-1_5_0_04\jre\bin;%PATH%;

C:\eclipse\eclipse.exe -vmargs -Xmx256M

But…when I run xDoclet, I get two outcomes now. If the web.xml does not exist in my webroot of my project then I get the error:

I simply can’t reproduce this, here is what I did, take a look and see where our steps differed.

1) Created new WebProject, TestWebDoclet
2) Created com.test package
3) Created TestServlet in the com.test package, the contents are:


package com.test;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * @web.servlet name="checksess" display-name="Check Session" load-on-startup="1"
 * @web.servlet-mapping url-pattern="/chksess/*"
 */
public class TestServlet extends HttpServlet {

    /**
     * Constructor of the object.
     */
    public TestServlet() {
        super();
    }

    /**
     * Destruction of the servlet. <br>
     */
    public void destroy() {
        super.destroy(); // Just puts "destroy" string in log
        // Put your code here
    }

    /**
     * The doGet method of the servlet. <br>
     *
     * This method is called when a form has its tag value method equals to get.
     * 
     * @param request the request send by the client to the server
     * @param response the response send by the server to the client
     * @throws ServletException if an error occurred
     * @throws IOException if an error occurred
     */
    public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        out
                .println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
        out.println("<HTML>");
        out.println("  <HEAD><TITLE>A Servlet</TITLE></HEAD>");
        out.println("  <BODY>");
        out.print("    This is ");
        out.print(this.getClass());
        out.println(", using the GET method");
        out.println("  </BODY>");
        out.println("</HTML>");
        out.flush();
        out.close();
    }

    /**
     * The doPost method of the servlet. <br>
     *
     * This method is called when a form has its tag value method equals to post.
     * 
     * @param request the request send by the client to the server
     * @param response the response send by the server to the client
     * @throws ServletException if an error occurred
     * @throws IOException if an error occurred
     */
    public void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        out
                .println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
        out.println("<HTML>");
        out.println("  <HEAD><TITLE>A Servlet</TITLE></HEAD>");
        out.println("  <BODY>");
        out.print("    This is ");
        out.print(this.getClass());
        out.println(", using the POST method");
        out.println("  </BODY>");
        out.println("</HTML>");
        out.flush();
        out.close();
    }

    /**
     * Initialization of the servlet. <br>
     *
     * @throws ServletException if an error occure
     */
    public void init() throws ServletException {
        // Put your code here
    }

}

Note: At the top I tried to duplicate your XDoclet tags.

4) Added Standard Web doclet to the project
5) Right clicked on project > MyEclipse > Run XDoclet, got the following output:

Buildfile: D:\My Documents\My Development\Eclipse\testing-workspace\TestWebDoclet\.xdoclet-build.tmp.xml

Can you see where our steps might have differed? Can you try exactly whta I did?

My original project stills does not work. Would it matter that the original web project was created with Eclipse 3.0.1 and MyEclispe 3.x? That is the only thing that I can think of right now. I imported the project into the Eclipse 3.1 environment.

jimmy,
There is something goofy going on here, try and shut down MyEclipse and add -clean to the command line argument, then restart MyEclipse. Now try and run XDoclet, did it work?

If not, try and create a new web project, and drag and drop your existing web project into it, overwriting everything. Now try and run Xdoclet (after possibly closing/reopening the project), did it work?

If not, try and crteate ANOTHER new web project, and slowly move your old web project into it piece by piece, and configuring it the same way. Now run XDoclet, did THAT work?

If NOT, then rip out some hair and check your build path of your project. Do you include XDoclet JARs or any Java runtime JARs in your buildpath other than the ones provided by the system? Do you have anything cookey that might be in the classpath when XDoclet is running casuing it to die? Are you trying to use GNU Classpath for example? GCJ? Any custom runtime libraries?

I created a new web project and copied the source files over and the xDoclet ran fine. There must be something persisted in the project that was created by the Eclipse 3.0.1, even though it was imported into 3.1.

But…I have no idea what it could be. Thanks for your help.

Glad it’s working, I am confused as well.
