hi all,
I want my applet to flash the browser window, came to know that can be done
using applet javascript communication.
ne1 has ne idea how to do that.

Applet/javascript communication with 1.4 plug in

I have a javascript function that queries an applet parameter using the following code:
var applet = window.parent.frames["FRAME_NAME"].document.applets[0];
var errorStatus = applet.ErrorStatus;
The applet has a "getErrorStatus" method. This all worked fine using the 1.3 plug-in, but doesn't work at all with the 1.4.1.01 plug in! It seems to be listed as bug 4599575, but that bug is listed as being fixed in 1.4.0 Beta 3, and I'm using a more recent version! Does anyone know anything more about this bug, or has anyone found a good work around? Thanks!

To call an Applet's public methods in JavaScript, just do this:
var applet = window.parent.frames["FRAME_NAME"].document.applets[0];
var errorStatus = applet.getErrorStatus();

Applet - JavaScript communication problem

Hi,
I am creating applet parameter using JavaScript (DOM Tree). But when i am accessing inside the applet, it is coming as null.
Here is code:
JavaScript Code:
<html>
<head>
</head>
<script language="JavaScript">
     function testXML(){
          var applet = document.getElementById("graftApplet");
          var param = document.createElement("param");
          param.setAttribute("name","graft4");
          param.setAttribute("value","25:10|20:50|172:220");
          applet.appendChild(param);
</script>
<body onload=testXML()>

Java Applet to Javascript Communication

There is a Java Applet which digitally signs files after taking
private key from a smart card.This applet takes external files.
I want to do this "Generate digital signature of a web page with the
help of an applet of which the applet is itself a part"
I am trying using Java Applet to Javascript Communication.
I am able to access the object which represents the HTML document.
That abject is represented by document itself.
Now I have to somehow generate the whole webpage i.e. like we view in a
notepad like this:
<HTML>
<Title>my page</title>
Then write into a file and then that file can be signed.
This is what I feel.
In C#.net there is a method .innerhtml.
Does such kind of a method exists in Java.???
I m searching but cudn't get till now.
Will serialization work??

Kindly forget the previous post. Read the following:
JSObject browserWindow = JSObject.getWindow(this);
JSObject doc = (JSObject)browserWindow.getMember("document");
Here doc represents the object of the HTML document.
This is accessed using Java Applet JavaScript Communication.
I want to serialize the object represented by doc.
Then write it into a file and generate it's digital signature.
In the below written line the parameter fileName is passed.
CertificationChainAndSignatureBase64 signingResult = signFile(fileName);
For this I have added few lines in the code written below.
see first 10-30 lines. Though this code gets compiled but it is not running. When I want to sign the file , it throws an error
"Unexpected error:sun.plugin.javascript.ocx.JSObject"
This code is just one class. Two other classes are needed to completely test the code.
Should I post them ??
Kindly see what is the error.
I will be highly grateful and Sorry for confusing in the previous mail...
private void signSelectedFile() {
try {
// Get the file name to be signed from the form in the HTML document
JSObject browserWindow = JSObject.getWindow(this);
JSObject mainForm = (JSObject) browserWindow.eval("document.forms[0]");
String fileNameFieldName = this.getParameter(FILE_NAME_FIELD_PARAM);
JSObject fileNameField = (JSObject) mainForm.getMember(fileNameFieldName);
//This is another modification
//String fileName = (String) fileNameField.getMember("value");

Applet/Javascript/JSP Communication

I have defined the following for applet/javascript communication in my applet class
JSObject topWindow;In my init() method I initialised topWindow as follows
topWindow = JSObject.getWindow(this);I wrote this call to javascript in my applet destroy method.
String userDetailsString[] = {String.valueOf(userCount), String.valueOf(userNumber)};
topWindow.call("closeWindow", userDetailsString);My javascript method is as follows in my html page which has the applet
function closeWindow(args)
           var userCount = args[0];
      var userNum = args[1];
      var filename = "http://localhost:7001/decrement.jsp?userCount="+userCount+"&userNum="+userNum;
      win1 = window.open(filename,'Logoff',config='height=100,width=200,toolbar=0,scrollbars=0,resizable=0,left=300,top=75');
   }This decrement.jsp call is a file on Weblogic and its supposed to decrement the value of userCount for the UserNum using a sql update query which are passed from the applet to javascript and then to this jsp.
When I close the browser which should call the destroy method in the applet nothing happens and my javascript is not triggered. I do have MAYSCRIPT in my applet tags and also have the MAYSCRIPT as a param with true as its value within applet tags.
Where am I going wrong and also have I used the args variable in my javascript correctly to retrieve the values from the applet into the javascript?
Thanks

Try to use window.eval("..") That could help sometimes!

Signed applet and javascript communication

Hi All,
I have an (jar) signed applet which I use to access system properties (e.g user.home). I also have a javascript code that communicates (call to a public function) with the applet to get the property "user.home" from the applet. Everything works fine in Java plugin 1.3 but since I have installed the latest plugin 1.4.2_01 from http://www.java.com/en/download/windows_automatic.jsp website I can not access the system properties even though everything in the code is same.
I can however still access public functions/variables from the same applet which do not access system properties in the new plugin 1.4.2_01.
The browser I am using is IE and OS is Windows 2000.
Does anybody know if Sun has changed the security policy for 1.4.2_01, in the new plugin for java-javascript communication to block access to functions which uses system property,fileIO, socket etc. even if they are signed applet??
Thanks in advance..

When invokin applet methods via javascript, you are accessing privileged actions from an unsafe source.
Depending on your needs, you could either load the system variables in applet init into class variables and return the information contained in the class variables to javascript or wrap the method calls inside AccessController.doPrivileged() calls.

Applet/servlet communication for byte transmission

Hello all !
I wrote an applet to transfer binary file from web servlet (running under Tomcat 5.5) to a client (it's a signed applet) but I have a problem of interpretation of byte during transmission.
the code of the servlet is :
        response.setContentType("application/octet-stream");
        ServletOutputStream sos = response.getOutputStream();
        FileInputStream fis = new FileInputStream(new File(
                "C:\\WINDOWS\\system32\\setup.bmp"));
        byte[] b = new byte[1024];
        int nbRead = 1;
        while (nbRead > 0) {
            nbRead = fis.read(b);
            System.out.println("octets lus = " + nbRead);
            sos.write(b, 0, nbRead-1);
        fis.close();
        sos.close();et le code de l'applet qui appelle cette servlet est :
        URL selicPortal = null;
        try {
            selicPortal = new URL(
                    "http://localhost:8080/AppletTest/servlet/FileManipulation");
        } catch (MalformedURLException e) {
            e.printStackTrace();
        URLConnection selicConnection = null;
        try {
            selicConnection = selicPortal.openConnection();
        } catch (IOException e) {
            e.printStackTrace();
        selicConnection.setDoInput(true);
        selicConnection.setDoOutput(true);
        selicConnection.setUseCaches(false);
        selicConnection.setRequestProperty("Content-Type",
                "application/octet-stream");
        try {
            InputStream in = selicConnection.getInputStream();
            FileOutputStream fos = new FileOutputStream(new File(tempDir
                    + "\\toto.bmp"));
            byte[] b = new byte[1024];
            int nbRead = in.read(b);
            while (nbRead > 0) {
                fos.write(b);
            in.close();
            fos.close();
         } catch (IOException ioe) {
            ioe.printStackTrace();
        }the file dowloaded is broken. it seems that bytes 01 00 or 00 01 are not correctly process.
Some ideas to help me please ?

hi,
have you solved this issue.. please post me the code since i m also doing the applet/servlet communication and can use your code as reference.
how to read the content placed in the urlConnection stream in the servlet
Below is my code in applet
public void upload(byte[] imageByte)
          URL uploadURL=null;
          try
               uploadURL=new URL("<url>");
               URLConnection urlConnection=uploadURL.openConnection();
               urlConnection.setDoInput(true);
               urlConnection.setDoOutput(true);
               urlConnection.setUseCaches(false);
               urlConnection.setRequestProperty("Content-type","application/octet-stream");
               urlConnection.setRequestProperty("Content-length",""+imageByte.length);
               OutputStream outStream=urlConnection.getOutputStream();
               outStream.write(imageByte);
               outStream.close();
          catch(MalformedURLException ex)
          catch(IOException ex)
How can i read the byte sent on the outstream (in above code) in the servlet.
Thanks,

Asynchronous applet-servlet communication

Hi all,
I am trying to implement asynchronous applet-servlet communication and need your help. Anything would help(I tried with synchronous applet-servlet communication but doesn't solve my problem).
Thanks,

http://java.sun.com/docs/books/tutorial/networking/index.html
You can open a socket connection. Bother the client and the server
can have separate threads for reading and writing and that you gives you
asynchronous communication. Later, if you think the server is generating
too many threads and not scaling, you can use features of .java.nio to
make it more scalable:
java.nio.channels

Is there a good advanced review on applet-servlet communication

I am working on a web application and unfortunately experiencing a lot of trouble trying to use an applet as front end which interacts with a couple of servlets running on Tomcat. I need to get data from one servlet and send data to another.
There is a lot of messages posted in this and other forums about how to do this, but none of them got a response pointing to a useful advanced reference on this subject. I have reviewed some of the references given, but couldn't find a thorough detailed advanced reference on applet-servlet communication. For this I mean an exhaustive explanation of the mechanism of communication and when and when is neccesary to use each of the multiple configuration possibilities regarding content-type, message-length, request-method, connection settings, and so on.
Would anybody be so kind to show me the right direction? As I read the (literally) hundreds of messages posted on this topic, I see this info as widely useful. Most of the topic tracks ends on void or with painful no-way sentences, and maybe many people is avoiding Java technology on web application because of this problem (development delays can abort a project).

This sample chapter in Java developers' guide to Servlets and Jsp focuses on Applet-Servlet communication, is a pretty good one, and is free :
http://www.javaranch.com/bunkhouse/samps/2809ch12.pdf
As to an exhaustive & complete guide that covers absolutely everything, I may be wrong but I doubt you'll find anything like that...unless there is a book somewhere dedicated to the subject.

Applet-servlet communication, object serialization, problem

hi,
I encountered a problem with tomcat 5.5. Grazing the whole web i didn't find any solution (some guys are having the same problem but they also got no useful hint up to now). The problem is as follows:
I try to build an applet-servlet communication using serialized objects. In my test scenario i write a serialized standard java object (e.g. a String object) onto the ObjectOutputStream of the applet/test-application (it doesn't matters wheter to use the first or the latter one for test cases) and the doPost method of the servlet reads the object from the ObjectInputStream. That works fine. But if i use customized objects (which should also work fine) the same code produces an classnotfound exception. When i try to read and cast the object:
TestMessage e = (TestMessage)objin.readObject();
java.lang.ClassNotFoundException: TestMessage
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1359)
    at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1205)
    at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319)
...That seems strange to me, because if i instantiate an object of the same customized class (TestMessage) in the servlet code, the webappclassloader doesn't have any problems loading and handling the class and the code works fine!
The class is located in the web-inf/classes directory of the application. I've already tried to put the class (with and without the package structure) into the common/classes and server/classes directory, but the exception stays the same (I've also tried to build a jar and put it in the appropriate lib directories).
I've also tried to catch a Throwable object in order to get information on the cause. But i get a "null" value (the docu says, that this will may be caused by an unknown error).
I've also inspected the log files intensively. But they gave me no hint. Until now I've spend a lot of time on searching and messing around but i always get this classnotfound exception.
I hope this is the right place to post this problem and i hope that there is anyone out there who can give me some hint on solving this problem.
Kindly regards,
Daniel

hi, thanks for the reply,
all my classes are in the web-inf/classes of the web-app and have an appropriate package structure. thus the TestMessage class is inside a package.
i tried some names for the testclass but it didn't matter. the exception stays the same. I also tried to put the jar in the common/lib but the problem stays.
Well the problem with loaded classes: As i mentioned in the post above i can instantiate an object of TestMessage in the code without any problems (so the classloader of my webapp should know the class!!)
only when reading from the objectinputstream the classloader doesn't seem to know the class?? maybe theres a parent classloader resposible for that and doesn't know the class?
strange behaviour...
p.s. sending the same object from the servlet to the client works well
regards
daniel

Applet/Servlet communication - StreamCorruptedException

Hi, I'm having a problem when I try to connect to a servlet. I am using applet/servlet communication. The problem only occurs when I have lauched a crystal report via http in a new window.
After the report is launched if I try to hit my servlet I get the following error:
java.io.CorruptedStreamException: invalid stream header
Not all crystal reports I launch cause this behavior but I can see nothing in the url I use to launch the report that is out of place or different than other reports.
APPLET-SERVLET CONNECTION
try {
StringBuffer path = new StringBuffer();
path.append(ip);
path.append("servlet/DatabaseServlet?");
path.append("option=getRecords&query=").append(URLEncoder.encode(query,"UTF-8"));
URL url = new URL(path.toString());
URLConnection servletConnection = url.openConnection();
servletConnection.setUseCaches(false);
servletConnection.setDoInput(true);
servletConnection.setDoOutput(true);
servletConnection.setRequestProperty("Content-Type", "application/x-java-serialized-object");
ObjectInputStream inputFromServlet = new ObjectInputStream(servletConnection.getInputStream());
rc = (RecordCollection) inputFromServlet.readObject();
inputFromServlet.close();
} catch (Exception e) {
e.printStackTrace();

context.showDocument(new URL(launchURL), "_blank");
} catch (Exception ex) {
ex.printStackTrace();
SAMPLE URL THAT CAUSES PROBLEM
http://localhost:113/Reports/OpenToBuy_3.class?promptOnRefresh=0&user0=rpuser&password0=er34sw1&[email protected]=rpuser&[email protected]=er34sw1&user0@sub2=rpuser&[email protected]=er34sw1&promptex-key="L","L1","ALL"&promptex-start="1"&promptex-years="2004","2004"&promptex-title="Report Title"&promptex-end="1"&promptex-locs="01","03","04","05"&promptex-period="Feb 2004 [04-01]"&promptex-cw="1"&promptex-cy="2004"&promptex-time=-2-52728"
Everything works fine until I launch this report then I can no longer get data from my servlet. I thought the URL lenght for the report might be the problem but I lauch a report with a URL longer than the problem one and there I don't get the errors after. When I try to connect to the servlet the println statement in the doGet method of my servlet doesn't get printed so it's not even making it inside that method in the servlet.
Anyone have any idea what could be causing this? Anyone have any ideas what would be causing this? I'm really stumped.

I've seen this problem before. Because your accessing a complete URL (ie http://<host>:<port>/xxx), you are actually creating a new session. Whenever the applet opens a connection to a servlet it is running on it's own session not the same as the JSP. This is rather obvious since the Page and Applet are separate entities.
Try sending authentication with the url. I think the syntax is:
username:password@http://localhost/xxx
However I'm not sure how well this might work for Tomcat. As for Java it may try and throw a MalformedURLException I would have to test it first - it's been a long time since I used this technique!
Wish I could be more help,
Anthony

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,
          Subir Das

          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 in Signed Applet while communicating with Javascript

Hi,
Im facing a problem with applet. Applet calls JavaScript methods and vice versa. Applet works fine with JRE 5 to JRE 6 up to build no 1.6.0._7 but it fails with build no 1.6.0_10.
The problem description is given below:
After embedding applet in my HTML page using <OBJECT> tag, Ive to check either any problem during applets execution, I want to get the error reason by calling my defined method getErrorReason() in applet that returns the error reason, I call the getErrorReason() against the applets object in JavaScript immediately after embed applet code in my HTML page, a JavaScript errors occurs and my applet fails to perform its execution.
JavaScript error: Object does not support this property.
The error points to the HTML page area where Im calling getErrorReason() against applet object.
The above JavaScript error occurs after the successful completion of Applets init(). Im facing this problem only in JRE 6 build 1.6.0_10-b33.
Please suggest me any solution.
Thanks in advance.

We are using the HttpURLConnection. If I have to go down the stack to the Socket object, well I guess I have to re event the wheel so to speak.
I have tried both Connection: close and Connection: Keep-Alive. Not at the same time :) but in different intrim releases of test applet.
// Here is the current incarnation of how I am trying to connect.
URL url = new URL(sURL);

connection.setDoInput( true );
connection.setRequestMethod("POST");
connection.setUseCaches( false );
connection.setInstanceFollowRedirects( true );
connection.setAllowUserInteraction( false );

connection.setRequestProperty("Expires", "-1");
connection.setRequestProperty("Connection", "Keep-Alive");
connection.connect();
// Now I write our form POST data and flush and close the output stream.
BufferedOutputStream bos = new BufferedOutputStream(connection.getOutputStream());
bos.write(sForm.getBytes());
bos.flush();
bos.close();
// Get the input and read

With the above code in place what I am now seeing, as opposed to a premature EOF exception, is blocking behavior on the read.

Problem in Applet while communicating with Javascript

Hi,
Im facing a problem with applet. Applet calls JavaScript methods and vice versa. Applet works fine with JRE 5 to JRE 6 up to build no 1.6.0._7 but it fails with build no 1.6.0_10.
The problem description is given below:
After embedding applet in my HTML page using <OBJECT> tag, Ive to check either any problem during applets execution, I want to get the error reason by calling my defined method getErrorReason() in applet that returns the error reason, I call the getErrorReason() against the applets object in JavaScript immediately after embed applet code in my HTML page, a JavaScript errors occurs and my applet fails to perform its execution.
JavaScript error: Object does not support this property.
The error points to the HTML page area where Im calling getErrorReason() against applet object.
The above JavaScript error occurs after the successful completion of Applets init(). Im facing this problem only in JRE 6 build 1.6.0_10-b33.
Please suggest me any solution.
Thanks in advance.
Regards,
Israr Ahmed

Hi Bharath,
Even i got similar error and i tried deleting the below(Attaching the stack trace is always better way.)
1) delete the folder workspace or rename(including all files and subfolders) in the path D:\Documents and Settings\lzcr8r\Documents\SAP\workspace
2) delete all .dtr/.dtc/.metadata directories in your personal folder (e.g. C:\Documents and Settings\lzcr8r).
Restart the IDE once you are done with the above steps.
Second part to increase the virtual mem
1) RtClick on the Shortcut of NWDS -->Properties and in the Target put the below
"C:\Program Files\SAP\IDE\IDE70\eclipse\SapIde.exe" -vmargs -Xms512m -Xmx1536m "C:\j2sdk1.4.2_08\bin\javaw.exe"
2) You can also try Creating a bat file with the complete path of your IDE and start your ide from the bat
content in the bat eg: "C:\Program Files\netbeans-4.1\bin\netbeans.exe" -vmargs -Xms512m -Xmx1536m
Here -Xms512m is the min JVM size and -Xmx1024m is the max JVM size.
You can place this batch file anywhere and double click the batch file.
It will automatically start your IDE
3) if you are using Tomcat you can try creating an env variable and assign Value
Variable Name: CATALINA_OPTS
Variable Value: -server -Xmx800m
please award points if usefull.
Regards
Souza
