Applet should call Servlet

I want to a applet to post a request to sevlet after clicking on the applet's submit button and activate the doPost request of servlet. Is it possible. Or only HTML forms can do this? Plz give me an idea.
How to move from one applet to another. That is, how to give links from one applet screen to another applet screen?

An Applet can make a connection back to the server that it was loaded from. (Note it must match exactly so localhost is not the same as 127.0.0.1). You can use the Java HttpUrlConnection class but I prefer using the Apache Commons HttpClient package.
As for moving from one Applet page to another you can use Applet-JavaScript communication provided by LiveConnect.

Applet that calls servlet

How to achieve something like this: i ve got a simple applet that calls servlet or JSp. when i get the response i would like to show it like a new page canceling the previous one with applet. Please Help. I have no idea how to using the data from response produce a new page. Nay resources hints??

In the second case:
You want to use the URL and URLConnection to POST or GET information to the server
that the applet came from (if not you have to sign the applet or set up policy).
The response from the server should be opened in a new window.
To post the data:
http://javaalmanac.com/egs/java.net/Post.html
This will get you a string, after you got that string you can use JSObject to call a javascript
method.
for example your applet:
import netscape.javascript.*; // either in jaws.jar or plugin.jar in your lib dir
..... extends Applet{
public Sting newpage;
... method that opens URLConnection and receives response in strRes
this.newpage = strRes
JSObject win;
win = JSObject.getWindow(this);
win.eval("methodThatOpensWindow()");
The html page looks like
<object ...... id="myapplet" myascript="true">
function methodThatOpensWindow(){
var win = window.open('','','');
win.document.write(document.getElementById("myapplet").newpage);
...

How do you use a main applet to call other child applets?

Hello Everyone!
I have created three separate applets that animate different colored walkers that walk across the web page with each applet doing what I need them to do. I need to create a main applet that displays a component that allows the user to select how many walkers(1-3) they would like to see displayed walking across the screen. The main applet should call only one walker applet if 1 is selected, call two applets if 2 is selected, or call all three applets if 3 is selected.
My textbook has covered how to call other classes in an application but not a main applet calling other applets. I have gone through the tutorials but have not found anything related to what I need to do. Google didn't have any good ideas.
Another possibility that would work would be to have one applet with each walker having its own method to be called based upon the selection. Then again, my textbook didn't cover calling methods within an applet.
Any hints or suggestions would be greatly appreciated on these issue.
Thanks.

Remember, an Applet is nothing more than a Panel (or JPanel for a JApplet) - basically an empty graphics container waiting for UI or graphics commands.
You do not have a "main" applet as you do when you create an executable application which requires the 'main' method.
The best thing to do, is simply do an HTTP Redirect to a page created with the desired number of "walkers". In your cause, the most you'd need is 3 walkers, so 4 pages - 1 redirect page, and then a page with 1 walker, a page with 2 walkers, and a page with 3 walkers.

How to call a Applet from a servlet and vice versa...?

Hi all
Can anyone help me how to call a applet from a servlet and vice versa. When the applet is called it should contact the database (oracle8i) and get the data. When i submit the applet form the data in the applet should be saved in the database.
Thanks in advance
Kamalakannan

Sweep is correct about requestDispatcher being another approach for inter-servlet delegation; the only issue that i recall with this approach is that it defaults the method of the destination servlet to the one it was called from...for example, calling servlet2 from within servlet1.post() resulted in the dispatcher attempting to utilize servlet2.post() - i believe that i searched for a parameterize solution to no avail :( (ended up handling the request by placing a "fake" doPost() in servlet2 that simply called servlet2.doGet())
however, if your application is functioning correctly on your pc/webserver then the problem may be external to servlet communication (e.g. client webserver's ports not configured or blocked, missing runtime classes, etc.)
my suggestion would be to set aside the programmatic concerns for the moment - what is the response if you open a browser on a client's machine and access the URL in question (i.e. http://clientserver:port/stefanoServlet)? If it will not respond to access in this manner then it certainly won't when your application calls for it.
It's possible that there is a coding error but, given the info supplied, i'd start examining the environment, first. Let us know if you have any luck with the test i recommended or not (please provide abundant detail). Or, if you've found the solution then you may want to post back with a quick blub so the next person knows how to escape the trap.

/jaw6c/build.xmlThe applet should be loaded in my "darstellungErgebnisse.jsp"-File.
Now the strange situation:
When I access "darstellungErgebnisse.jsp" DIRECTLY by entering a URL like "localhost:8080/jaw/darstellungErgebnisse.jsp" , the applet is loading perfectly !
But when my server is forwarding me to the JSP-Site with
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(destinationPage);
dispatcher.forward(request, response);
. . . . . . . ..I'll get a ""java.lang.ClassFormatError: Incompatible magic value 1008813135 in class file diagram
" -Error what means (referenced on the articles I've read here), that the diagram.class Is not found !
I have tried to put the class file in a JAR, in different locations... using the codebase and archive tag but NOTHING solved my problem.
So my question:
Why I'm able to access the JSP-File directly and seeing the applet but after forwarding to the JSP-File via the Servlet, I'm not able to see anything.
Would appreciate your help
Thank you and best regards
Edit:
1) I'm able to download the diag.jar and diagram.class file from different locations
2)I recognized, that after using the servlet, my url is changing from
localhost:8080/jaw
to
localhost:8080/jaw/controller
I tried added the class file to the position, where the controller-class file is, but without sucess.
3)Opening the class-file with a hex-editor shows me, that
the first bytes are
"CAFEBABE0000002E02B9070002010007"

Hello everybody,
I finaly have found the solution (after 16 hours).
Like I mentioned before, I recognized (maybe a little to late), that my path is changing when I'm using the servlet :
localhost:8080/jaw
to
localhost:8080/jaw/controller
(made by url-pattern in my web.xml).
So when my JSP tries to acces the class file, It's looking at:
localhost:8080/jaw/controller/applet/diagram.class
but the file is in:
localhost:8080/jaw/applet/diagram.class
So the solution is, to but a codebase-tag in my applet-declaration with following delcaration "basedir="../applet"
I hope I'll help somebody with the same problems. It took me a day to find out, that the solution was two points and a slash..... lol
Regards to everybody

When should a servlet be called?

Hi all,
i have three JSP pages.when should a Servlet be called.what is the interaction between jsp,servlet and data base.please help me with the process flow.its urgent.help me out.thanks in advance.

JSP's should represent the presentation. It should not contain Java code nor scriptlets.
Beans should contain the actual data which is to be transferred between JSP and servlets (business objects / value objects).
Servlets should contain the business logic (the actual Java code) to check/verify values of business objects and call DAO's. Generally here the BO's will also be mapped to DTO's (data transfer objects). Some solutions uses DTO's as BO's, or at least extends them.
DAO's should contain the logic to create/read/update/delete DTO's into/from database.

Applet in a servlet

I have an applet class in my webserver directory. How do i call it within a servlet .What should be the values for code and codebase properties. Kindly send me an example code if possible.
Bye for now
Thanx in advance
Naveen

You don't call an applet from a servlet. But if you want to include the applet in the HTML generated by the servlet, there are no special rules that apply because a servlet generated the HTML. Just follow the usual rules for applets embedded in HTML.

Re: [Fwd: Java Applet IIOP Call-In with Release 3C--How dowe speed up d

Hi Michael,
We have done exactly what you describe and have avoided the slow applet
download times. Although it can be a bit tricky, it is possible to use
the ORB bundled inside the Netscape 4.0 browser (Visibroker for Java by
Visigenic). Most of the code should follow Netscape's examples (on
http://developer.netscape.com)--just remember to initialize the ORB by
passing a reference to the current applet in orb_init() (so that you
invoke something like orb_init(this) [assuming you are extending
java.applet.Applet]). Pulling up the Java console within your web
browser should help debug quite a bit (a lot of debug messages will get
printed there the ORB is having problems).
Netscape has just implemented the applet caching schemes you describe,
so it probably shouldn't matter too much if you use another vendor's
ORB (we've done this with Iona's OrbixWeb). If you use ZIP files, they
have to be uncompressed, and I don't think that the browser will cache
them between browser sessions. Netscape 4.0 does seem to handle
compressed JAR files just fine and it does indeed cache them between
browser sessions. I'd go with the JAR format anyway since the ZIP
bundling was just a workaround until Sun got their act together in the
1.1 JDK.
By the way, you also might want to take advantage of the code-signing
and capabilities APIs of Netscape if you are going to invoke methods on
objects not resident on your web server. Otherwise, you will probably
run into the (in)famous browser applet security restrictions and you may
have other problems doing things like callbacks from Forte, etc.
If you want more detail on how it works, let me know and I can post some
examples.
Oh, one last thing: we are a consulting firm specializing in these kinds
of things :)

Subject: Java Applet IIOP Call-In with Release 3C--How do we speed up download time.
Date: Wed, 2 Jul 1997 09:10:31 -0500
From: Michael Nelson <[email protected]>
To: "'[email protected]'" <[email protected]>
We have successfully implemented a simple Java Applet that calls into
Forte Services via IIOP. However, the duration of the download time
for
Applet and its required class files is UNACCEPTABLE in a typical
INTERNET environment where 28.8K modems and multiple hops around the
net
are not uncommon. We dialed into our network at 28.8K (but no
hopping),
and found that download times varied from 1.5 - 2.0 minutes. This is
unacceptable, even by internet standards. We have been using the
Visigenic Visibroker product as the ORB.
After doing some investigation, we've come up with several ideas to
speed up download time:
1. Figure out how to use the Visigenic components (CORBA/IIOP class
files) that come bundled with the latest version of the Netscape
Navigator browser, so that they don't have to be downloaded
2. Figure out how to use ZIP files. Here's what I've read: "Since
the
introduction of Netscape Navigator 3.0, you can specify an
uncompressed
.zip file as an addition to the code base of your application. By
specifying a ZIP file, the browser will load your applet's classes
from
a specified ZIP file before it searches the code base. This ZIP can
improve applet download time by reducing the number of HTTP
connections
required to fetch applet code. As an added benefit, Netscape caches
the
single ZIP file so that it will not reload your applet unless the date
of the ZIP file has changed."
3. Figure out how to use JAR files. Here's what I've read: "JAR
stands for Java archive. It's a file format based on the popular ZIP
file format and is used for aggregating many files into one. Although
JAR can be used as a general archiving tool, the primary motivation
for
its development was so that Java applets and their requisite
components
can be downloaded to a browser in a single HTTP transaction, rather
than
opening a new connection for each piece. This greatly improves the
speed with which an applet can be loaded onto a web page and begin
functioning. The JAR format also supports compression, which reduces
the
size of the file and improves download time still further."
Unfortunately, we've been unable to get any of these approaches to
work.
Has any one used these or other approaches to speed up applet
download
time? Or, does anyone know of consulting firms that specialize in
this
sort of thing?
Thanks in advance for your help.

How to forward an applet page to servlet/jsp?

I have an applet in imageMap.jsp file. This applet displays a map. When user enters the page of imageMap.jsp, they will see the map . If user clicks a point of the map, the latitude and longitude of that point should be sent to Search.java servlet and search results should replace the current page.
My Search.java servlet works well.
I think I should add mouse event in the applet. I can use MouseEvent.getX() and MouseEvent.getY() in the applet to get latitude and longitude. But I do not know how to go from this applet to servlet. How can I forward applet page to servlet?

The <jsp:plugin> action is used in pages to generate client specific HTML tags involving download and execution of the applet that is specified in the tag.

2 threads in one applet should use paint()

hello,
i'm new to java and my english is bad - so sorry for this.
i read faqs and documentations, but still i don't know.
i've got applet with two threads in it. each thread should independently paint some stuff.
my idea: i need a intelligent paint method, which recognizes the sender.
is it possible to overwrite the paint method?
public void paint(Graphics g, String sender)
all my tries failed. i don't know how to handle the repaint() method.
presumable this idea is not the right way.
so, how can two threads in one applets share the paint() method?
thanks for any help

If you employ AWT you should paint in the paint method, overriding it, just like YATArchivist example.
If you employ AWT You must'n override the paint method never or you won't be able to paint properly. you must override the paintComponent() method, the first line in this method must be a call to the parent's method: super.paintComponent() and then put the code for painting. You must call super's methos because it deals with some stuff, like buffering. and (I think but not sure) flickering.
Ehen you want you Swing component to be reapinted never call directly paintComponent method, you should call repaint().
I prefer drawinf in Swing, it deals automatically with the flickering trouble, which you must do by hand in AWT.
About how painting from the threads employ YATArchivist idea: draw in a buffer in each thread, this buffer must be employed by the paincomponent() mehtod, assuming you choose Swing, and after the dawing cll repaint().

Hi Sandip,
You can try below blog which can help you to call a Java method from BPEL process Java Activity,
this can be a good starting point from where you can call java class,
However I have never tried calling servlet from BPEL.
Why do you want to call a servlet from BPEL?
