Applet-Adf communication help!

Version 11.1.1.3.0
So i have a USe case:
Where i have a ADF serach screen..simple serach get result in table.Then from table i need to select row and click on View button.
from View button we need to show the image which we can zoom in/out and can do other stuff.
So on view button i want to call applet which will show the image.(there are many other reason to use applet so we have to use appplet)
i created a jsff page on which i have applet code(Applet.jsff) like this
applet.jsff
<?xml version='1.0' encoding='windows-1252'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"
xmlns:af="http://xmlns.oracle.com/adf/faces/rich"
xmlns:f="http://java.sun.com/jsf/core">
<af:panelGroupLayout id="pgl1">
<applet code="sni.edms.model.applet.NewApplet" height="100" width="1000"
archive="/edmsui/adflibEDMSApplet.jar"></applet>
</af:panelGroupLayout>
</jsp:root>
I have a task flow(T1) where i have jsff page with ADF Search screen(Adf.jsff) and i drag the Applet.jsff page and link the two.
Now when i click on view button i get the applet screen and it show up correctly with correct data but with the below UI error(which display as dialog box)
"Assertion failed:Incorrect use of ADFRichUiPeer.GetDomNodeForCommentComponent.AdfRichCommandLink"
I know thsi error comes on incorrect use of tags but i havent use Commnd link, and its throwing link error.
My Question is..Can we call applet code from jsff page if not then how do i call applet code from adf screen.
if we can then whats wrong with my jsff applet page.
Thanks..any help will be appreciated.

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,
my platform is Salaris 5.8 + iPlanet 6.0.

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..
below is the piece of code...

Applet Jsp Communication - Help Required

Hai ,
well i have to just pass some text from an applet to the JSP ... how can i do it ???
the Applet is Embedded in the same HTML page which has the jsp scriplets ...
help me please ...
PeterIyer

thanx for that ,
but i have a applet which conatins some data and i have to basically write it on the clients machine.
as it is not possible for me to write on the client machine thru applet(i believe i am correct), i want to pass that data to some JSP so that i can download that from there ...
i tried the URLConnection. though i was able to send the data to the JSP page i was unable to open that page from my applet. if i use the showDocument of the appletcontext class i am unable to get the data i have passed thru the URLCOnnection object..
how can i solve this problem ... please Help me ...
here is the code that i wrote .. it has no errors .. i believe
     try
               URL appletURL = getCodeBase();
               String strHost = appletURL.getHost();
               String strPort = String.valueOf(appletURL.getPort());
               String strProtocol = appletURL.getProtocol();
               int portNumber = Integer.parseInt(strPort);
               String strwp ="/DMig/download.jsp";
               URL jspURL = new URL(strProtocol,strHost,portNumber,strwp);
               URLConnection jspCon = jspURL.openConnection();
               jspCon.setUseCaches(false);
               jspCon.setDoOutput(true);
               ByteArrayOutputStream byteStream = new ByteArrayOutputStream(512);
               PrintWriter out = new PrintWriter(byteStream,true);
          String postData= "?xmlText=" + URLEncoder.encode(genXml(),"UTF-8");
          out.print(postData);
          out.flush();
          String strLength = String.valueOf(byteStream);
          jspCon.setRequestProperty("Content-Length",strLength);
          jspCon.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
          byteStream.writeTo(jspCon.getOutputStream());
          URL tempURL = new URL(jspURL+"?"+postData);
          getAppletContext().showDocument(tempURL);

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

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();
SERVLET CODE
Forwards to doPost
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
System.out.println("session id: " + request.getSession().getId());
this.doPost(request, response);
LAUNCHING REPORT FROM APPLET
try {
String launchURL = host + directory + report + "?promptOnRefresh=0"+ "&" +

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

Search Function does not work in Community Help

Thanks in advance for anyone that can help.
I use the Adobe Master Suite and have enjoyed the Community Help Application/Client. I could do online searches for information with no issues. In checking were I stood as far as offline documenation, I decided to download all of the Suite Documentation through the CHC Perferences through the Updater Settings and doing a manual download. I believe (though not positive) is when my problems began.
First, I have a MacBook Pro runing OSX 10.6.8 with FireFox Browser 9.01 (not sure the browser information is needed). Adobe Community Help Version is 3.5.0.23 and the Adobe AIR application is version 3.1
At this point I am able to view the online help files in the main viewing screen. However, when I try and do a search, nothing shows up excpet a little dynamic clock icon showing that it is working and eventually it comes back with a dialog that says: "An unexpected error has occured. Please try your search again."
Here is the screen shot before the search:
And here is the image after trying a search:
After several attempts to fix this myself, I am not asking help on the forum. The last attemp I made was to
- Uninstall AIR using the uninstall app under Applicaitons/Utilities/Adobe AIR Uninstaller.app
- Deleted the folder "user"/Library/Preferences/chc.4875E02D9FB21EE389F73B8D1702B320485DF8CE.1
- Running the AIR installer (I downloaded the most recent version): Adobe AIR Installer.app
- And then running the Adobe CHC help application directly: Adobe Help.app
If I set preferences to open up in a Browser, that works just fine yet would prefer to use the CHC interface.
Thanks in advance for any help including pointers on how to dig myself out of this hole I seem to be in.

ADDED EDIT: When I click the OK button on the error dialog, the main view window again shows the Adobe help information as in the first image.

There is a thread on the topic on the Photoshop forum: http://forums.adobe.com/message/4124703#4124703
Strange, it works in CS4
But you guys are able to go to http://help.adobe.com/en_US/photoshop/cs/using/index.html right?
It might be useful to know that you can set Community Help Sites as a search engine in your browser (it should offer you to register itself as a search engine, while Safari users have to add Glims to add additional search engines.) http://blogs.adobe.com/communityhelp/2009/01/opensearch_plugins_available_f.html

New update for Community Help application - version 3.5 now available

Hi: just a quick announcement that the engineering team has released version 3.5 of the Adobe Community Help application. This update is a very significant release that directly addresses a lot of the feedback that we’ve been hearing from the community. The most significant changes include:
Feature
Benefit
1.
Tabbed Browsing
Ability to open multiple pages   from multiple sources simultaneously
2.
Favorites/Bookmarks
Ability to bookmark your   favorite URLs; note: we prepopulate a set of suggested bookmarks for you   based on the products you have installed. Users can of course   add/edit/delete any bookmarks that they choose and can organize them via   folders, etc.
3.
Search/Browse History
Ability to view previous pages   browsed or search results (including previously used filter options, search   collections, online/offline search status, refinements, and more).
4.
Flash Platform ASLR
Ensures developers only   have to download one copy of the ASR and not separate, multiple copies for   Flash vs. Flex, etc.
5.
Revamped local content   download workflow
The entire local content   download workflow has been reworked! We have removed the pop-up dialog   box and moved the “content update” notification to the footer of the app as   well as the homescreen. This ensures an uninterrupted workflow for   users who simply want to access content first and foremost.
6.
Performance improvements
The team has worked especially   hard on improving the start-up and browsing performance by consolidating a   number of disparate server calls into a single initialization service that is   only performed at launch. This enables us to cache a number of assets   and reduce network calls/dependencies.
7.
Silent application updates
Similar to the changes in the   local content download experience, we have also revamped the update   experience for the application itself! Going forward, app updates will   be downloaded in the background without interruption to the user workflow.
8.
Set-and-forget search options
Search options are now sticky   from session to session – for example, if you check the Search Adobe   Reference check box for Photoshop, the CHC will remember those options   the next time you open the app. This applies to refinements too.
9.
Much more!!
Minimize to sytem tray (for PC   users only); upgrade to Flex 4.1 and AIR 2.5; and many, many other   enhancements, fixes, etc.!
Note: many of these features were part of our earlier 3.4 release – as some of you know, we had to pull down that release shortly after launch due to server/hardware issues. So only a few users were able to update at the time. CHC 3.5 is now a general release that will support all users and has been extensively tested to ensure robust performance and stability.
To update your app, simply open the Community Help application from your hard disc or visit our download page on adobe.com:

Scroll wheel not working in Community Help App (Windows 7 64bit)

I am using the Community Help App on both a Windows 7 32 bit machine and a Windows 7 64 bit machine.
On the 32 bit machine, the mousewheel scrolls the content pane just fine.
On my 64 bit machine, the mousewheel will not scroll the content pane. I have to use the scroll bar on the right (click and hold to scroll the content).
This appears to the be case for all Adobe Air apps, as this functionality is identical in Adobe Story.
I am using a Microsoft Wireless Mobile 4000 mouse on the Windows 7 machine.
Is anyone else having this problem on 64 bit Windows 7 machines?

I'm frustrated, too, because of the scroll wheel issue with any AIR applications.
Running Windows 7 Home Premium N 32 bit.
Using Microsoft Comfort Optical Mouse 3000 (wired, not wireless) - current drivers.
Scroll wheel will not work when rolled normally, no matter what sensitivity I set the wheel to. To get any scrolling action, I have to roll the wheel as fast as I can. Then, it will scroll, but in horrible chunky bits, which ends up being wildly inaccurate and extremely frustrating.
I've heard of many other people having this issue. It's only when the program I'm using is an AIR application, which leads me to believe that Adobe did something to make AIR incompatible with a MS mouse & Win 7 OS. (I have used the same mouse running Vista and scrolled fine in an AIR application.)
Is Adobe going to correct this situation?

Error message in trying to use local content in Adobe Community Help of Flash Builder

Hi,
I have set my Adobe Community Help application preferences of Flash Builder to 'Display local content only'.to Yes.
I also disabled my internet connection to use local help content only.
I get the following error message when trying to access any of the links from Help home page.
To view the requested page, connect to the Internet or deselect "Display Local Help content only" in Preferences.
I understand this is due to all the links point online HTTP urls.
But why cannot the local help content be accessed when it is already downloaded to local and the 'Display local content only' option is set to Yes?
This saves me a lot ot time otherwise using Adobe Community Help is painful even for a short period of time.
Thanks,
Ram Manoj Kongara.

Hi, Ram -
To help troubleshoot your problem, can you please do the following:
In the Adobe Community Help application, go to Edit > Preferences.
Select Local Content.
The list of Help packages downloaded locally appear. Make sure that the status of every Help packages reads “Current”. If the status of a Help package reads "Out-of-Date”, select that Help package, and click Update to download the latest Help package. Note that to do this, you have to be connected to the Internet. Once you fully download the Help packages to your desktop, you can access Help offline.
One other thing that I would want you to check is the Adobe Community Help Client version that you are using. To check that, in the Adobe Community Help application, go to File > About Adobe Help. The build version should be 3.2.0.610.
Let me know if this helps. If the issue still persists, we can investigate further.
Thanks,

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

How do I re-find my 'Community Help' preferences?

I had that 'Access denied' error message whenever I tried to access help within Flash CS5 (that's pretty bad). I searched for far too long and found the obscure solution.
During the process I decided it might be safer to access the online help from my browser in the meantime. But with the problem solved I want to switch back to viewing the content through the Flash IDE.
I can't find those preference settings again though, please help!

To do so, return to this Preference page by reopening the Community Help application from your hard disk.
The application will be present in "Programs " -> "Adobe Help" if in Windows.
Or
goto your installed location for e.g. C:\Program Files\Adobe\Adobe Help\
and then click "Adobe Help.exe"
The in the application press "Cntrl + K " or got to Edit->Preferences.
hope this helps.
