How to Compali this SERVLET????

This is how my servlet class looks like. Any body can give me some hints on how to compile this servlet class.
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Form extends HttpServlet {
     public void doGet(HttpServletRequest request, HttpServletResponse response)
     throws ServletException, IOException {

     String title = "Investment Form";
     out.println(ServletUtilities.headWithTitle(title) +
          "<BODY BGCOLOR=\"#FDF5E6\">\n" +

          + request.getParameter("Amount") + "\n" +
          "</UL>\n" +
          "</BODY></HTML>");

You can compile your servlet as you do for ordinary classes.
like
javac servletfile.java
but do check before you compile that, your servlet.jar or j2ee.jar is there in class path or not.
after compilation put your servlet class in the classes dierectory of your Webserver.

Sorry.
actually this is my coding on the bottom.
Pleease disregard my previous coding. I got the different one.
My first approach is using <% %> around the whole doGet method such as:
<%
String[] ids = { "hall001", "hall002" };
setItems(ids);
setTitle("All-Time Best Computer Books");
out.println("<HR>\n</BODY></HTML>");
%>
I am not sure how to break between code between
return;
and
response.setContentType("text/html");
Here is my coding:
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
     String[] ids = { "hall001", "hall002" };
     setItems(ids);
     setTitle("All-Time Best Computer Books");
if (items == null) {
response.sendError(response.SC_NOT_FOUND,
"Missing Items.");
return;
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String docType =

public class WebMail extends HttpServlet{..}The sample code is not OK, as it does not define where to find HttpServlet or things like HttpServletRequest. Then even if your classpath is allright, the compiler still does not know what is 'HttpServlet'.
If you look at http://java.sun.com/j2ee/tutorial/api/javax/servlet/http/HttpServlet.html you'll see that its full name is javax.servlet.http.HttpServlet. So either use the full names, like in
public class WebMail
extends javax.servlet.http.HttpServletand
public void doGet(javax.servlet.http.HttpServletRequest ...)or (preferred) simply add the following line at the top of your code:

How to place a servlet file in Tomcat 5.0?

Hi,
i'm using Apache Tomcat 5.0 as myweb server.i don't know how to set the class path and where to place my servlet and html files,and how to run my servlet file.if anybody knows plz give me a detailed description abt this topic.

Look at the directory structure of your Tomcat installation directory. You will see a webapps directory under that. The Tomcat installation comes with samples ready to run. Look at those and create a similar directory structure under webapps for your application. I don't think you need to worry about classpath. Tomcat should be taking care of all that if you create the proper directory structure.
You run your servlet by specifying a url like:
localhost:8080/servlets-examples/from a browser. This assumes that your installation is using port 8080 which I think is the norm for Tomcat. Here "servlets-examples" is the name of the directory you created. Actually Tomcat 5.0 comes with a "servlets-examples" application. This would be a good directory to look at. You could also run their examples to get a feel for it.
If you are new to servlets, you'll probably have to get a book that explains how things need to be set up. You'll need to create a web.xml for your application. If you look at the servlets-examples directory under webapps, you'll see that it has a WEB-INF directory under it and that directory contains a file called web.xml as well as a sub-directory called classes. This structure is standard accross all application servers because it corresponds to the war (wars are specialized types of jars for web apps) file standard.

How to create a servlet in PAR Application

Hi Experts,
I want to create a servlet in PAR application. This servlet should be capable of accessing the functions of other java files included in PAR Application. Servlet should be capable of accessing the functions say doContent(req, resp) of any class of PAR application.
Is it possible to create Servlet in PAR application?
I created one servlet but unable to declare its information in Deployment Descriptor.
Because the deployment which is provide ie portalapp.xml doesnt allow us to write tags like <servlet-name>, <servlet-mapping>, <url-pattern> etc. These are necessary for declaration of servlet.
So how can i write a complete working Servlet under PAR application?
Please help and replies will be appreciated.

Your javascript code contains a syntax error. That's why the function isn't being called. Take a look at this line in your code.
if ((m>12 && m<100) || (m> = 100 && m<1000) || (m==0))Notice the space between > and =. Remove that space.
m >= 100

How to create a servlet and write its details in DD in PAR Application

Hi Experts,
I want to create a servlet in PAR application. This servlet should be capable of accessing the functions of other java files included in PAR Application. Servlet should be capable of accessing the functions say doContent(req, resp) of any class of PAR application.
Is it possible to create Servlet in PAR application?
I created one servlet but unable to declare its information in Deployment Descriptor.
Because the deployment which is provide ie portalapp.xml doesnt allow us to write tags like <servlet-name>, <servlet-mapping>, <url-pattern> etc. These are necessary for declaration of servlet.
So how can i write a complete working Servlet under PAR application?
Please help and replies will be appreciated.

Hi Pankaj,
I don't think it is possible to write Servlet in portal applications.
I guess in Portal Application Projects we can develop portal components and portal services only.
Thanks and regards,
-Madhu

How to create the servlet as acontroller and how to use it

how to create the servlet as acontroller and how to use it

Please update your forum profile with a real handle instead of "914824".
When you have a problem you'll get a faster, more effective response by including as much relevant information as possible upfront. This should include:
<li>Full APEX version
<li>Full DB/version/edition/host OS
<li>Web server architecture (EPG, OHS or APEX listener/host OS)
<li>Browser(s) and version(s) used
<li>Theme
<li>Template(s)
<li>Region/item type(s)
With APEX we're also fortunate to have a great resource in apex.oracle.com where we can reproduce and share problems. Reproducing things there is the best way to troubleshoot most issues, especially those relating to layout and visual formatting. If you expect a detailed answer then it's appropriate for you to take on a significant part of the effort by getting as far as possible with an example of the problem on apex.oracle.com before asking for assistance with specific issues, which we can then see at first hand.
I am going to have over 50 buttons in a page, Why? This would be a most unusual UI paradigm. I've never seen such a page, which suggests that whatever you want to do is normally done another way. Please explain the requirement in more detail.
just wanted to know if its possible to do something like this in java.
Java is not used in programming APEX UI behaviour. Java and JavaScript may share initial syllables, but they are not closely related.
It's possible to achieve a great deal in JavaScript, but a clear definition of the requirements is necessary. Do you mean the buttons should be dynamically generated? If so, yes, this is possible in JavaScript. What would drive the process?
Also, i would like to have dynamic action on it, for example, when the button is pressed, fill a string of text into other items(text field) within the page. Without more detail its not possible to make any specific suggestions. For example, I certainly would not want to create 50+ individual dynamic actions relating to different buttons.

How to restart the Servlet Engine?

Hi
I am configurating a WebDAV repository in KM
I am required to restart the Servlet Engine.
Can anyone please explain me how to restart the servlet engine.
Thanks in advance
-madhu

Basically it means to restart the Java engine!
On way to do this is to use the NetWeaver Administrator tool (http://portal:port/nwa) and navigate to Administration -> Systems -> <Your SID> and then you will see your dispatcher and server nodes. Just restart the server0..n nodes.
Cheers

How to determine the Servlet which current request is mapped to

Hello folks,
having a filter, i want to discover the servlet (if any) which will serve the current request. I want to have it before the chain execution. Does someone has an idea how to accomplish this using Servlet API? The old API provided the getServlet(String name) method for this task. Here the sample code:
Servlet servingInstance = discoverServlerForRequest(request); //i look for implementation of this method
chain.doFilter(request,response);I know that it would be very easy to get the servlet AFTER processing the chain, but the clue for me is to get it before.
Maybe Tomcat has implemented some special servlet context attributes to map it?
any hint appreciated!
thanks

its possible, for sure. but then I need two filters to achieve it. I'll post my solution later, if there wont be any other ideas. I know that tomcat maps many objects by attributes...maybe there is a key for it.
