JRE/JDK Problem with Applet/Servlet scenario
Hi there!
I'am forced by my company to upgrade an old Java application. The situation is, that an signed applet calls several servlets (running on Tomcat 4.x or 5.x) over http(s).
In former times both, servlet container and applet, were using jre 1.4.1.x
(The servlet container was ServletExec, so a jre was sufficient).
Everything was working fine, if the client was using the 1.4.1 jre.
But on later versions (1.4.2.x) the whole Applet-jar was downloaded from the server per user interaction, whats definitly not acceptable as customers still using isdn or nowadays umts.
Any sugesstions?
Thanks
Buzz

And the answer is the same. You will have to open multiple connections. One for each time want to send data to the Servlet, because that is how HTTP works.
Try a simple case, where you want to send a single object through to the Servlet, then read the response.
When that works, repeat it for every subsequent time you want to send or recieve data.
If you want to have continuous communication between the server and the client, you do not want to use HTTP.

Netscape problem with applet servlet communication
Netscape always seems to get in the way when you use applets, right?
I have a nice set of code from a book that shows how to do applet->servlet stuff.
But although I'm doing this all in the privacy of my own localhost Netscape immediately put a spanner in the works with a security exception and wouldn't let the servlet respond.
Anyone know what to do here.
The answer is to use Internet Explorer, possibly, but I'm in linux, and I can't get Opera to work with java yet.
Anyone got any ideas? Thanks.I encountered a security exception with Netscape in Linux when attempting applet-servlet stuff but that's prpbably because I haven't got the plugin for that yet...in fact I don't know if a plugin is available for sure...let me know if you do. As a matter of fact I plan on using the HTMLConverter this weekend to find out if it'll download a plugin.
The applet-servlet thing runs fine in IE and Netscape on my Windows box as long as the plugins are there and I use the appropriate plugin tags in the HTML
Post what you find out,

Problem with Applet Servlet communication
Hi All,
i am very new to java and servlets......
i am using a applet to call a servlet whose .class file is stored in WEB_INF/classes directory of tomcat..
so what URL address i should use in the new URL( ) constructor ????
presently i have done in this manner..
URL urlServlet = new URL("http://l0.0.2.65:8080/myapp.ServletDB");
URLConnection con = urlServlet.openConnection();
where ServletDB is the name of the servlet .class file
whose address is as follows...
C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\myapp\WEB-INF\classes\ServletDB.class
Please help me....
thank you in advance
vijaySpecify Servlet Mapping in web.xml and use that mapped URL

Problem with Applet for Microsoft VM
Hi there!
I implemented an applet (first for SUN JVM 1.4.1_02) that has to communicate with a servlet via serialized objects. Therefore the applet sends a request and expects the response :
//establish connection
URLConnection l_con= l_url.openConnection();
l_con.setUseCaches(false);
l_con.setDoOutput(true);
l_con.setDoInput(true);
l_con.setRequestProperty("Content-Type", "application/x-java-serialized-object");
//send request to servlet
ObjectOutputStream l_outputStream = new ObjectOutputStream(l_con.getOutputStream());
l_outputStream.writeObject(l_obj);
l_outputStream.flush();
l_outputStream.close();
//get response
ObjectInputStream l_obInStr = new ObjectInputStream(l_con.getInputStream());
l_response = (MyResponseClass)l_obInStr.readObject();
l_obInStr.close();This works absolutely fine for the Sun VM. Now I have to use the Microsoft VM (because I don't want the users to install anything on their clients).
I compiled the client classes like that:
javac -target 1.1 classname.javaThe applet starts correctly but there is a problem with the communication that I recognized in the console:
java.io.IOException: Cannot write output after reading input.
at com/ms/net/wininet/http/HttpURLConnection.getOutputStream (HttpURLConnection.java)
at myclass/MyApplet.callToServlet (MyApplet.java:109)
Does anyone know what this error means ?
Thanks a lot in advance.Hi there!
I solved my problem by removing all the System.out.println-statements that I used for debugging issues.
Anyway, I want to know if there are more restrictions concerning this matter for using the Microsoft VM instead of the Sun VM. (Because it HAS worked with the debugging statements with the Sun VM).
Thank you. -
Big Problem in Applet-Servlet Communication-(Help)
I wrote an method to send serialized objects from Applet to Servlet,
the method is as following:
private ObjectInputStream postObjects (URL servlet, Serializable objs[], String sessionID) throws Exception {
ObjectInputStream in = null;
ObjectOutputStream out = null;
try{
URLConnection con = servlet.openConnection();
con.setDoInput(true);
con.setDoOutput(true);
con.setUseCaches(false);
con.setRequestProperty("Content-Type","application/x-java-serialized-object");
con.setAllowUserInteraction(false);
con.setRequestProperty("Cookie", sessionID);
out = new ObjectOutputStream(con.getOutputStream());
int numObjects = objs.length;
for(int x = 0; x < numObjects; x++){
out.writeObject(objs[x]);
out.flush();
out.close();
in = new ObjectInputStream(con.getInputStream());
}catch(Exception e){
e.printStackTrace(System.err);
throw e;
}finally{
return in;
when I call this method, I got the following error message in Applet console,

Please help me to solve this problem, thank you very much.Hi..
Sorry abt this. But I was hoping if u could help out on this..
I am trying to implement a applet to servlet communication...
wherin the servlet would read data from the database... and send it back to the applet which gets displayed on the applet...
But the problem is that the applet is not able to establish a connection with the servlet..
I am also using another supportive class whose object is basically passed from the servlet to the applet..
could u help me..

Problem in Applet Servlet communication in cluster
Our new production server has been configured with
clusters very recently.The application is running fine if and only if one instance
of weblogic is running.The application has two applets that communicate through a
servlet and the servlet is hosted by both the WL servers in the cluster.
Please consider the following scenario :
1. JSP#1(having embedded tag for Applet#1) is served by, say, WLInstance#1.
2. JSP#2(having embedded tag for Applet#2) is served by, say, WLInstance#2.
3. Applet#1 is loaded by BrowserInstance#1.
4. Applet#2 is loaded by BrowserInstance#2.
The way I understand applet-servlet communication is as follows :
The servlets are invoked through the url-pattern specified in web.xml - if the applet
is making use of a certain url-pattern that is mapped to servlet, then the call from
that applet will
eventually invoke a servlet on any of the two instances till a session is established,
at which point all subsequent requests from the same browser window/frame will go
to the servlet hosted on the instance where the http session was created.
(Please correct me, if I am wrong.)
So, Applet#1 will always talk to the servlet hosted by WLInstance#1 and Applet#2
will always talk to the servlet hosted by WLInstance#2.
In our case, the servlet is maintaining data structures to store all the messages
sent by diffterent instances of Applets.
The applets periodically polls the messages from those data structures.Once the messages
are polled, those are deleted from
the data structures.
As there are two different instances of the servlet, Applet#1 never gets messages
posted by Applet#2.
Is there a way to make this data structure global to both the servlet instances?
Thanks and best regards,

This statement is not entirely true.
Suppose WLInstance#1 were to be brought down (for whatever reason), Applet#1 will
then talk to servlet hosted by WLInstance#2.
Server pinning could be modified by different load balancing algorithms, configurable
via containers (or hardware).
So don't count on which servlet instance your applet is going to be served by.
Instead consider to give a second look into the design of the servlet data structure
(object):
1.Read from data store, if it has been persisted.
2.If the data is client related then consider sticking the data into session, which
would then replicate to other WL instances.
3.Stateless EJB in a cluster ? Don' know much about this(yet).
My 2 cents..Good luck.

Problem with Applets in same page
Hai to all,
I am having a problem with GUI in applets
My first class extends a JPanel named A_a
import javax.swing .*;

text=new JTextArea(5,20);
add(text);
public void text_appendText(String aa)
System.out.println("I AM IN A_a");
text.append(aa);
text.revalidate();
revalidate();
/*public static void main(String ags[])

frame.getContentPane().add(a);
frame.pack();
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) { System.exit(0); }
frame.setSize(200,200);
frame.show();
and then I am using other class B_b which is an applet carries a exitsing panel (A_a) inside it .

Hi,
I have a SOAP servlet, but It is the fist SOAPServlet as I use.
I think that the vsd that developper of SOAP servlet provide is ok.
But, I do not understand which is the XML that I could provide to it.
It is posible that I have a problem with XML, SCHEMA and SOAP.
Could you help me , I attach the VSD, but I need a tool or a sample file in order to call my SOAP servlet.

</xsd:schema>Thanks youHi,
I have a SOAP servlet, but It is the fist SOAPServlet as I use.
I think that the vsd that developper of SOAP servlet provide is ok.
But, I do not understand which is the XML that I could provide to it.
It is posible that I have a problem with XML, SCHEMA and SOAP.
Could you help me , I attach the VSD, but I need a tool or a sample file in order to call my SOAP servlet.

Error loading class problem with applet (Newbie)
Hi,
I am new to Java applets. I try to display a simple sample. I put this into html file: <APPLET codebase="classes" code="NewApplet.class" width=350 height=200></APPLET>
And it always appears one problem:
Error loading class: NewApplet
java.lang.NoClassDefFoundError
java.lang.ClassNotFoundException: NewApplet
at com/ms/vm/loader/URLClassLoader.loadClass
at com/ms/vm/loader/URLClassLoader.loadClass

at java/lang/Thread.run
Can anybody help please? Thanks in advance.Now I am able to load the applet on MAC OS X 10.4.11. This is due to network issue.
Now my problem with the applet functionality. My applet will display the map image. Applet contains the navigation arrow keys at the top left of my applet. These keys will be used to navigate through the map.
The problem is while user using the navigation buttons, the image got squash and stretch.
This is happened only on MAC OS X 10.4.11 and Its working fine on PC and MAC OS X 10.5.5.
Please anyone help in this regard. Thanks in advance. -
Hi to everybody.
I've got a problem with simple applets.
I've built several applets using Swing components (JApplet, JPanel, JButton, etc.)
In my browser, the background color of my applets does correctly appear.
But none of my components does !!!! No text fields, no buttons etc.
Can someone explain to me which could be the reason of that ?
Thank's.I've just tried appletviewer. And I discovered that there is a problem while trying to acces to a jpeg file for my JBuutons and JLabel.
Appletviewer considers these files are on the client machine and refuses the acces.
But when I try my site, the server is my computer too ! So the jpegs are on the server side !
Furthermore, when I start my web page (that contains my applets), nothing does appear (no exception) in the java console...
How can I solve this problem (I'm newer with applets)? -
Still Having Problems With Applets!!!!
First i'd like to thank all who responded to my last post regarding a downloadable copy of the J2SE API Documentation. I have downloaded it and am quite content.
I am still, however having a problem with my applets (all applets at that). Like i said before. I can view any applets i want through the command prompt using appletviewer. My problem is residing in execution directly through Microsoft Internet Explorer 5.x.
When i open the .html file containing my applet, the file loads in the browser but the applet does nothing. When i mouseover the applet a message is displayed in the browser's status bar stating "loading class. classname: class not found".
I have tried every applet i can get my hands on including downloaded applets from applet resource sites (even the example applets that came with the JDK1.4 when i downloaded it). They all react the same way, but will execute fine with the direct command prompt reference to appletviewer.
It's getting very irritating. I have tries everything including setting the classpath in the command prompt. I'm loosing hope of a solution so if anyone might have an idea of what i need to do to fix my problem, or anything i am doing wrong or haven't done, please give me a hint or help.
I am loving the java language and wish to further my knowledge and farmiliarity with it but i need to make sure everything works.
Sorry for rambling and i thank whoever offers a reply in advance.
ChanceH1. Check the codebase parameter in the html file that calls the applet
for example if you have an applet named MyApplet.class inside a directory applets and your html file outside that directory you should have a codebase like this "applets/".
<applet CODE="MyApplet.class" codebase="applets/" WIDTH=640
HEIGHT=480 ALIGN= center>
</applet>
2. Be sure that your IE support java check the properties and enable the JVM.
3. If your JVM version does not support Java 2, applets build on Java 2 will not work. -
Problem with applet file loading
I have a problem with loading files into a java applet. import java.applet.*;
import java.awt.*;
import java.io.*;
import java.util.*;
import java.net.*;
public class main extends Applet {
private static ArrayList<String> SGM;
public void init() {
SGM = new ArrayList<String>();
String gameDir = getParameter("game_dir");
try {
File fHandle = new File(gameDir+"game.sgm");
Scanner fScanner = new Scanner(fHandle);
while(fScanner.hasNextLine()) {
SGM.add(fScanner.nextLine());
//System.out.println(SGM.get(0));
} catch(Exception e) {
System.out.println("Applet threw error: "+e);
...The problem is with File fHandle = new File(gameDir+"game.sgm"); I tried putting File(gameDir+"/game.sgm"); and appending / to the folder in the <PARAM> tag, but it still changes it to \, which means I can only run it locally, and in Windows. Why is it doing this, and how can I fix it?This file you were hoping to load: it's on the server, right? Not on the computer where the applet is running in a browser?
(At least that's a common mistake made by people when they write their first applet.)
If that's the case then you can't use a File object to access a file on a different computer. To access a file on the server, first you will have to put the file in a place on the server where it can be downloaded. Then in your applet you need to get a URL for the file. (The getDocumentBase() method can be used to prevent you from having to hard-code the full URL for the file.) Next, "this.getClass().getResourceAsStream(URL)" gets you an InputStream from which you can read the data from the file. -
Problem with Controller Servlet in WAS 4.0
Hello guys,
I am working on WPS over WAS 4.0. I have an Enterprise application
with a servlet which acts as a Traffic Controller. Its job is to
intercept every http request to the Portal Server and make some
changes to the URL and redirect/forward the changed URL to the Portal
server. I plan to map the servlet to "/" so as all the requests are
handled by this servlet. I hope it will work this way.
So, the user clicks on a URL like http://server_name/meeting, the
servlet sees a mapping table for /meetinf, constructs a new URL and
redirects it. I read the /meeting as "pathInfo" variable from the
request object. Please note that "/" is mapped to the servlet. This
works fine. But if I give a JSP file instead
(http://server_name/meeting/m.jsp), it starts looking for the JSP file
in the Servlet WAR file. So the question is if there's any any other
way of achieving this effect or is there any way to make all the .jsp
file requests to go to this servlet instead of being searched in the
WAR file?
I would be grateful if someone can put their thoughts over this
problem.
Thanks
Kapil.

Sorry to hear that.
As far as I know the campus topology is based on CDP info. And since you see all the links in the CDP tables, so should campus.
I've seen campus getting it wrong a few times, especially when there was some repatching done, but until now, when I delete the devices and re-add these devices, the next data collection gets the links correct.
Cheers,

Problems with Http-servlet : UTF-8
I am having some difficulty with UTF-8 encoded
chracaters in a Java servlet.
My servlet accepts an XML file conteining a question and returns an HTM page. The XML has cyrillic characters encoded as utf-8.. The rendering
servelt copes with this fine, and the HTML produced
displays OK in the browser (the response type on the
Java servelet has to be set to "text/html;
charset=UTF-8" for this to work).
I have to send cyrillic characters back in the
response to the question in a text field in the HTML form.The browser is
correctly sending back the byte stream (which I am
printing here as hex): d0b3d0bed180d0bed0b4 (this is a
cyrillic word correctly coded as utf-8).
However, on collecting the response (using
request.getParameterValues(fieldname)) the servlet
returns the byte stream: d0b3d0bed13fd0bed0b4.
A mistake in the fifth byte.
Can anyone help with this problem? Is there a known problem with the JAVA UTF-8 converter?
Regards
GrahamI now know the answer to this problem thanks to Bruno Van Haetsdaele .
Before calling request.getParameterValues(fieldname));
one should call request.setCharacterEncoding("UTF-8");
Hope that helps somebody else!
