Trying to run my first servlet through Eclipse + XAMPP
I'm trying to run my first servlet through eclipse, I'm using XAMPP + Tomcat add-on as my webserver. How do I even try and compile my servlet? I've added the external jar Servlet-api.jar to my project as stated in here, http://www.theserverside.com/discussions/thread.tss?thread_id=37924
But eclipse wouldn't compile it, because there just isn't a main() in my servlet program..
Do I need to install the WPT plugin for eclipse? I'm guessing I'm not setting my CLASSPATH correctly - Do I need to set it up manually?
Nevermind, there were lots of Issues going the XAMPP way, so I just installed Tomcat separately and all is fine now.
I used instructions from http://www.scribd.com/doc/495993/Installing-Apache-Tomcat-6-and-Using-It-With-Eclipse and it was a walk-in-the-park..

Fail to run my first Servlet with Sun ONE Studio 4 Update 1 (+ bi Tomcat)
Hello !
I failed to run my first Servlet with Sun ONE Studio 4 update 1 ( with built in Tomcat)
I think that I followed most of the online instructions,
so I successfully run a JSP file,
but I failed with my first servlet:
The error message is:
"Standard Wrapper[:MyServlet]: Marking servlet MyServlet as unavailable
javax.servlet.ServletException: Wrapper cannot find servlet class com.hemmerling.myservlet.MyServlet
or a class it depends on
So please don�t ask me for the code of the servlett ( simply taken from a book),
but tell me why the one-and-only servlett was not found. what might I have done wrong, if I did everything I did to run the JSP file, too ?
Of couse I copied the file into the "Classes" directory of the Webmodule ( WEB-INF ) and "processed" it, so that I was able to execute it.
Any suggestions ?
Tia
Sincerely
RolfTough to say, but try:
1. Put the servlet in a package. If you're using the default package (class file in WEB-INF/classes directory, then Tomcat may not find it.
2. Check out web.xml to ensure the <servlet> and <servlet-mapping> entries are correct.
3. Make the servlet as simple as possible so you're sure that it is the servlet itself that cannot be found and not some other class that it uses.

Trying for Run Direct Cash Flow through Trasaction code FSI0
Dear Friends,
When I am trying for Run Direct Cash Flow through Trasaction code FSI0 then it is giving error Financial Statement veriosn INT doesnt exist...
I want to Assign my Company Financial Statement veriosn MFSV instead of INT
can u please tel me how to Assing my compnay Financial Statement veriosn
please help me gurus...
Thanks,
SremHi
Can get the output in the reort by assigning your Chart of account and GL accounts pertaining to your COA. You have to click on the change Icon otherwise it will show as greyed out.
1) Preparation of FSV is a good option but how will you address "Change in receivables" like that items in FSV?
2) GL's can be linked to the report as told earlier.
3) Still in the process of exploring.
4) "Relevance to Cash flow" tick has no relavance with the cash flow report.
5) Activation of Cash management has no relevance with cash flow report.
6) There is no special configuration required for Cash flow.
The only problem here is getting the output for items like change in inventory etc. If this could also be brought in this report, it would be a wonderful report.
GL accounts can be mapped with this report. The problem you may be facing is due to the reason that you might not have clicked the change icon, that is why it is showing as greyed out.

Not able to run my first Servlet..... 404 error!!!
Hi,
I am new to Java.
I am trying to create a small servlet application. I am using Tomcat 5.5 server and eclipse for this.
I have first writtern a HTML form which on submission is redirected to a servlet that displays the information submitted. but i am not able to evn open the html file through browser, i am getting 404 error.
My html codes and Servlet codes are inside the htmlform package...
When i type http://localhost:8080/htmlform/form.html i am gettig 404 error... Also let me know if any thing is wrong with the codes...
Here is my code...
form.html
<html>
<head>
<title> This is a HTML page </title>
</head>
<body>
<p><h3>This page displays a submission form</h3></p>
<form method="GET" action="/htmlform/LoginServlet">
<p> USERNAME: <input type="text" name="username"/> </p>
<p> PASSWORD: <input type="password" name="password" /> </p>
<p> <input type="submit" value="Press Me" name="submit"/> </p>
</form>
</body>
</html>
LoginServlet.java
package htmlform;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class LoginServlet extends HttpServlet{
private static final long serialVersionUID = 1L;
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter pw = response.getWriter();
String username = request.getParameter("username");
String password = request.getParameter("password");
pw.println("<html><head><title>This is the out put page</title></head");
pw.println("<body><h2>If you can see this page then your form is cleanly processed</h2><br>");
pw.println("<h2>Congratulations!!!</h2>");
pw.println("<p>Your user name is: "+ username+ "</p>");

Thanks in advanceyou might have other problems, but I think the action attribute in your HTML form is incorrect.
You have:
<form method="GET" action="/htmlform/LoginServlet">Your web.xml says:
<servlet-mapping>
<servlet-name>Login</servlet-name>
<url-pattern>/login</url-pattern>
</servlet-mapping>So I think you should change the action like this:
<form method="GET" action="/htmlform/login">Your servlet's not in a package, and you might not be deploying it correctly (god forbid you added this to /ROOT), but try that first.

Running my first Servlet on TOMCAT - 10 duke dollars
I am very new to Servlets. I am not creating a seperate context on Tomcat root to load the Servlet.
I did the automatic installation of Tomcat 4.0.3 on windows NT available on <jakarta.apache.org/tomcat>
I am going to load my servlet class in c:\<Tomcat Home>\Web Apps\Root\Web-inf\Classes
But under my <Root\Web-inf> there is NO <Classes> subdirectory. So I created one and copied my class file there.
Then on the browser, I typed
http://127.0.0.1:8080/servlet/myFirstServlet
Then I am getting the 404 Http Not found error.
Error in detail is "/servlet/myFirstServlet" not found
Can someone PLEASE help me ASAP.NOTE: I already sent this message under different heading.. I am sending this message under this for Mr/Mrs w234 ....
Please let me know....
I wrote my first Servlet with Forms, for a registration system. I have my input HTML file first.html and my java class (first.java) which processes the form and spits out the same information thru' the servlet.
I added the line below in my server.xml in /conf directory, Forms is the subdirectory under webapps
<Context path="/Forms" docBase="Forms" debug="0"
reloadable="true" crossContext="true" />
I created the web.xml as follows in c:<Tomcat home>\webapps\Forms\web-inf\web.xml
<?xml version="1.0" encoding="ISO-8859-1"?>

</servlet-mapping>
</web-app>
Note : My HTML file name and class files name both are same.. Also can someone tell me how to change web.xml for different HTML file name and class name ? Or do we have to include HTML file here in web.xml ?
I am confused !!
Then in the browser I typed
http://127.0.0.1:8080/Forms/servlet/first.html
I am getting this error

Still I have not figure out how to give a couple of Duke s ? Please help me ... -
Error when trying to run my first Java app
Okay, Im new to Java programming. I started a day ago :). My question is after I compile my application like so.
javac TestGreeting.javaIt give me a .class file. So the next step is I want to run it so I do the following.
java TestGreeting.classWhen I run this I get this error:
Exception in thread "main" java.lang.NoClassDefFoundError: TestGreeting/classCan some one tell me what is going on? I am running Mac OSX Leopard on a MBP. I have the latest Xcode Tools which is 3.1 if I am not mistaken.
Thanks everyone. Go easy on a newbie :)The argument for the java command is the fully qualified Class Name. It is not a file name or path. You provided a file name. The JVM tried to find a class named 'class' in a package named TestGreeting. Most likely, you should have typed "java TestGreeting"

Can anybody shed any light on what might be wrong?
Any & all help gratefully received,
doug.Please check your web.xml file for the URL pattern defined for Faces Servlet. And you need to access the JSF pages based on this definition.
Ex:
* <servlet-mapping>
<servlet-name>FacesServlet</servlet-name>
<url-pattern>*.faces</url-pattern>
</servlet-mapping>
- the url "http://localhost/chooselocale.faces"
* <servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/guess/*</url-pattern>
</servlet-mapping>
- the url "http://localhost/guess/greeting.jsp"

Bhanu.Copy the jdev_home/jlib/redist/uix2_install.zip file to
jdev_home/jdev/redist folder . It will overwrite an existing uix2_install.zip file.
Close and open the Jdeveloper IDE. It will prompt you for upgradation of projects. Press OK button in response.
Now you should be able to run the JSP pages. -

I am trying to run my first servlet HelloWorld
I have my servlet in the directory
Tomcat 4.1/webapps/test/web-inf/classes/HelloWorld.class
and my web.xml file in the directory
Tomcat 4.1/webapps/test/web-inf/web.xml
contains the following lines
<web-app>
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>/HelloWorld</url-pattern>
</web-app>
I also have changed the conf/server.xml file for the context as follows
<Context path="/test" docBase="test" debug="0"
reloadable="true" crossContext="true">
and now when I try http://localhost:8080/test/servlet/HelloWorld
Still I am getting the error status 404 The requested resource /test/servlet/HelloWorld not found.
What am I doing wrong ????
When I put my HelloWorld.class file in the webapps/examples directory it runs fine.WHy is it so ?
Also for the above I have not started my tomcat server since I tried to run my HelloWorld from examples using http://localhost:8080/examples/servlet/HelloWorld it works perfect so I think I do not need to start server.
Please reply meTry fully qualifying your servlet-class so that it reads something like this: <servlet-class>examples.servlet.HelloWorld</servlet-class>

How to run a servlet in eclipse using "SAP Portal Plugin" ( not tomcat)
Hi All
I'm just trying to create a simple servlet in Eclipse using SAP Portal Plugin but I couldn't find any document.
I have an eclipse 2.1
EP6 SP2 patch 5
SAP Portal Plugin
I created a Portal Application Project.
I created a simple servlet and save it under src.core directory.
My question is as follow:
1) Which directory I should put in the file web.xml?
2) Do I export this as *.par file?
3) When I export it. Can I just call the servlet from the url?
Anyone help.. I really appreciate.
thanks much.
JenHi,
Portal plugin is used for developing SAP Portal applications ie Java iviews.
There is a set of procedures to develop Java iViews . You can develop either AbstractPortalComponent which is more or less equivalent of servlet in ordinary java world or JSPDynPage which is equivalent of JSP.
These plugins are used to develop any of the above portal components. If you are developing java applications for portal then you have to develop either of the above using the tools. These portlets( portal applications runs on Portal run time)
But servlets can run on J2EE itself.
But if your requirement is to develop servlet then you can create ordinary java project and deploy that in the J2EE server as like in any app server.

putting it in there would cause all hell to break loose (I love how the
