JSF 1.2 with SERVLET 2.3

Hi, i've download the latest JSF 1.2 RI but i can't see any page as i get the following error:
ava.lang.NoSuchMethodError: javax.servlet.http.HttpServletResponse.getContentType()Ljava/lang/String;
at com.sun.faces.context.ExternalContextImpl.getResponseContentType(ExternalContextImpl.java:277)

at javax.faces.webapp.FacesServlet.service(FacesServlet.java:198)
The getContentType method that the exception describes is only available in servlet 2.4 but i'm using a servlet 2.3 only container. Can i use JSF 1.2 with servlet 2.3 ?
Thanks

I'm 90% sure that you cannot. JSF 1.2 is intended to be part of Java EE 5.0. Since Servlets 2.3 are part of J2EE 1.3, I don't think that it will work.

Mojarra JSF 2.1.x servlet requirement or dependency

Can anyone tell me how to reconcile this information?
http://javaserverfaces.java.net/nonav/rlnotes/2.1.0/releasenotes.html
says that JSF (Mojarra) 2.1 series depends on a servlet 3.0 container.
But http://download.java.net/maven/2/com/sun/faces/jsf-api/2.1.2/jsf-api-2.1.2.pom,
the maven config for JSF (Mojarra) 2.1 (2.1.2, in this case), shows a dependency on a servlet 2.5 container
We currently have a sandbox environment set up with a stack that can only provide servlet 2.5, and it seems to be working, with some occasional hiccups. Are we in for surprises down the line, or is the official requirement or dependency different than the actual dependency? In other words, is a stack with servlet 2.5 really sufficient for including JSF 2.1.x?
Thanks,
Josh

Communicate with servlet after using Java Web Start?

Is it possible to communicate with servlet to get data back and forth
after using Web Start to download the client application?
The demos come with Java Web Start are applications which are
standalone, don't need communicate with the servlet on Web server
after being launched. I am wondering if it is possible, and how (HTTP
& JAX-RPC)?
Thanx in advance.

I've done this using HTTP. I get the server and port from the codebase:
BasicService bs = null;
try {
bs = (BasicService)ServiceManager.lookup("javax.jnlp.BasicService");
String codeBase = bs.getCodeBase().toString();
and use the java.net.HttpURLConnection and java.net.URL classes to send HTTP parameter values to the servlet and to receive results from the HttpURLConnection's input stream.

How to use JNI with Servlets

Hi
i was trying to do some example with JNI. I can use JNI with standalone Java application but I just cannot figure out how I can use JNI with Servlet.
Can some one show me a sample code using JNI with Servlets.
thanks very much

hi,
I am also facing the same problem,
when I am using JNI with stand alone application it works fine but when i tried to use it with a servlet It gives unsatisfied linker error

Problem with Servlets

Hi,
I am Tejas , a newbie with servlets. Now, I have a servlet which contains a Javascript method. On clicking a link , the Javascript method is called.
But however, I find that there is some trouble. I created a class called MainFrames.java, the object of which I am instantiating in the Javascript method.
But this code doesnt work properly. I have given the snippet below
out.println("<script type='text/javascript'>");
out.println("function threader()");
out.println("{");
out.println("alert('Inside Threader');");
out.println("<%@ page import=\"XcForm.MainFrames\"%>"); //I have a hunch that this statement is the problem
out.println("<%");
out.println("MainFrames mainframes = new MainFrames();"); //without the import statement above, the MainFrames.java class is not being recognised
out.println("%>");
out.println("}");
out.println("</script>");
Thanks in advance,
Tejas

Do not put presentation code in servlets. Put them in JSPs. And mixing serverside code (scriptlets) and clientside code (javascript) this way is indeed not going to work. That code will certainly not be executed in the order as you write. Serverside code is executed at the server and is finished when the response is completed. So any serverside code inside clientside code is alreay executed. Clientside code is executed at the client and will only execute when the response is completed (onload, etc) or when the client invokes it (onclick, onsubmit, etc). Further on, do not put business code in presentation code. Put them in servlets.

Some problems with servlet.jar and tomcat 4.1.27

Hello everybody,
I used to work with tomcat 3.3.1 and i've decided to use tomcat 4.1.27 now. The manual explains that we have to change de version of servlet.jar, it's done with servlet-2.3.jar but on tomcat starting i have this message:
jar not loaded. See servlet spec [...]. Offending class: javax/servlet/Servlet.class
what can i do, i've red all de documentation and i think all versions a OK??
thanks per advance
antoine

I am running Tomcat 4.1.18, so your configuration may be slightly different. I found the Servlet.class file you are missing residing in the Tomcat/common/lib directory in the Servlet.jar file. Check your path and also make sure your Servlet.jar file contains the missing class.

JSF table component with paging

Are you aware of any existing JSF table component with both navigation and paging ?
I want to display the content of a database table with a large number of rows. The table component should be able to navigate through the entire table content, but building only a small ResultSet and dinamically populate it with data as we perform navigation.
Thanks,
Cosmin

Thanks for the answer.
But data scroller just takes a ResultSet and display it with navigation. It doesn't know about the total number of rows in the table. It only display the number of records in the ResultSet.
What I am looking for is a data scroller which based on some input parameters knows how to split the table in several ResultSets, dinamically change the ResultSet and display the total number of rows in the table and not in the current ResultSet.

JSF 1.2 with WAS 6.1

Our current environment
WAS 6.1.0.9 and using jsf 1.1
Is it possible to upgrade to JSF 1.2 with upgrading to WAS 7 ?
Thanks

WAS7 already ships with JSF 1.2. JSF 1.2 is supposed to be backwards compatible with JSF 1.1 without any pains. Only keep in mind that any fixed bugs in JSF 1.2 may cause your application to behave different as opposed to JSF 1.1, especially when the application is developed so that it -either awarely or unawarely- relies on the presence of those bugs.

Source code of JSF implementation bundled with JDeveloper

Where can I get the sources of JSF implementation bundled with JDeveloper 10.1.3.1 (1.1_02-b08)?

Fair enough. Yes, as far as I know those implementation classes aren't available. Contacting Sun's consulting services is one option, of course. Make sure you get someone who has actual experience with the classes in question, rather than just anyone who happens to be on the bench right now, 'cos they'll charge you handsomely either way.
I take it you've considered decompiling the classes in question ? Obviously there are legal issues to consider if you go that route, but I've found the Kaffe tool handy before now.
http://www.kaffe.org/
The only other thing I can think of is taking a dig around the IBM site to see if any of their equivalent classes are available in source form. I've always used the Sun versions, however, so I've no idea how likely this is.
Ok, I'm out of ideas. Will be interested to hear if you come up with something even more devious.

Forward with servlets

Im using tomcat 4.06 and i have some problems with servlets and forwarding:
This is my servlet:

import javax.servlet.http.HttpServletResponse;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletContext;
public class NTenant extends HttpServlet {
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
String email = request.getParameter("tenant");
//insert new tenant into database.
System.out.println("Redirigiendo");
ServletContext sc = getServletConfig().getServletContext();
RequestDispatcher rdNext = sc.getRequestDispatcher("/tenantForm.html");
rdNext.forward(request, response);
System.out.println("Redirigido");
I get this error:
type Status report
message Servlet invoker is currently unavailable
description The requested service (Servlet invoker is currently unavailable) is not currently available.
This is my dir structure:

webapps\form\tenantForm.html
webapps\form\WEB-INF\web.xml
webapps\form\WEB-INF\classes\NTenant.class
webapps\form\WEB-INF\classes\TenantServlet.class
The problem is that i cannot find my html, what must i write here? sc.getRequestDispatcher("/tenantForm.html"); <-----

Dialogs with servlets

Hi
Does anyone know how to use dialogs with servlets? I'd like to show a confirm dialog on the client machine. My first idea was to use JOptionPane.showConfirmDialog as such in the servlet, but then of course de dialog pops-up on the server side, and not on client side.
Many thanks for the help,
Nic

You need to use javascript to confirm, ask questions, etc...
You can see :

Swings with servlets

Hi,
how we can use swings with servlets or jsps.
or
how we can display the browser in the swings.
please give me a valid answer with examples.

Hi,
Your question is not clear... are you trying to display HTML using swing components or are you trying to use swing in a server-side application?
Some Swing components (e.g. JLabel) natively support simple html, so:
JLabel lbl = new JLabel("<html>hello <b>world</b></html>");would result in a JLabel that looks with the word "world" in bold. If you need also frames, css and javascript support - you'll need to reach for a 3^rd^ party library, I'm afraid.
As for using swing in servers, look at this article:
http://today.java.net/pub/a/today/2006/04/20/bringing-swing-to-the-web.html
If you meant neither, please explain more.
Hope this helps, though.
