JavaScript to Applet call freezes the Browser

Hi,
I am using javascript to applet communication to do some processing in my current project. The processing done in the applet is little heavy, whenever applet is processing the request, Browser freezes and user is not able to work with browser anymore. Even if you try to open new browser window its response is very slow.
Basically browser window is not able to refresh its contents and appears to be freeze to the user while the applet is processing the request.
is anybody faced this ( javascript to applet communication) problem earlier?
Any solution/workaround to this problem?
Thanks,
panyog

Martin,
Thanks for your reply. whatever you have mentioned is correct. Applet is eating up the resources. But the problem is browser window is not getting refreshed appears
to be freeze.
Following are the details of the scenario
1) Browser opened with mutilple processing option to the user.
2) User selects some of them for processing and call process.
3) here we have used javascript call to send for processing to the applet .
Here javascript call to Applet, one by one getting processed.
4) Applet starts processing, displays that an options
are getting processed, please wait. ( here the window appears closes.)
5) Once the window is gone, the browser which was previously
opened is freeze . All the text and all are lost nothing is visible.
Applet is still processing further requests, for user the browser is freeze.
User try to open another browser window, Window opens up but it is
really slow.
How can we refresh the browser window?
javascript reload does not work as it tries to process the option again?
from applet we cannot refresh the Browser window...
Is there any way we can it?
Thanks and Regards,
panyog

  • Why does xmark continue to freeze the browser on my macbook?

    Dear Volunteer,
    An "xmark" comment box, in extremely poor English continues to pop up when I open Firefox 4 on my Macbook, running osx 10.5.8.
    It freezes the browser and will not allow any other actions - indicating that I am to close Firefox and restart it. When I do the same operation occurs and freezes the browser. I find no way to remedy this.
    Additionally, all safety certificates come back as not safe, with a "Get me out of here" comment.

  • Javascript to applet calls with Java Plugin

    Hello,
    I'm working on getting existing applets to work with Sun's Java Plugin (v 1.3.1_03). I'm not sure how to modify calls to the applet from JavaScript. For example:
    document.applets[0].getClientHomeFromEnvironment();
    This works fine using the regular browser VM in IE or Netscape, but is not valid when using Sun's Plugin. I found the following in the Developer FAQ:
    Q: Does Java Plug-in support Java-JavaScript communication?
    A: Yes, Java Plug-in supports basic, bidirectional Java-JavaScript communication. The following, however, is a known incompatibility.
    In the Microsoft implementation, applet methods and properties exposed in JavaScript are exactly the same as the methods and fields in the applet object. In Java Plug-in, an applet's methods and properties are exposed in JavaScript through JavaBeansTM introspection, which treats the applet's fields in a different manner than the Microsoft VM. Therefore, JavaScript accessing fields in an applet object may not work the same when run on JRE/Java Plug-in.
    But it's still not clear to me how I would go about calling the applet. Has anyone done this successfully?
    Thanks,
    -Dave Meier.

    Yes and no....
    I'm using the internal browser JVM when the user has NS < 6.0 and IE < 5.0. But.. if they have NS 6.0+ or IE 5.0+ and have the browser configured properly, it hands off to the plugin. That does work.
    If you must use the OBJECT or EMBED tags... Your best bet are the release notes for the plugin to see what they say about Java-JavaScript support. You could start here...

  • Extensive tracing of liveconnect calls kills the browser

    i'm testing liveconnect from a simple example with mozilla 1.4 under linux
    and irix with java plugin versions 1.4.*
    my test looks like this:
    public class jsbug extends Applet implements Runnable {
    public void init() {
    win = JSObject.getWindow(this);
    public synchronized void run() {
    try
    for (;;) {
    wait(100);
    win.getMember("document");
    } catch (Exception eall) {}
    the problem is always the same
    any use of liveconnect method produces some tracelines
    (in tracefile or console-window) like
    OJIPlugin acq Spontaneous pipe=10
    Trying to enter spont monitor: 0
    OJIPlugin release for:Thread[Thread-24,4,file:/.../-threadGroup]
    OJIPlugin releasePipe - exiting spont monitor
    Current thread:Thread[Thread-24,4,file:/.../-threadGroup]
    OJIPlugin: No AThread
    after some times i'm ending up with a browser crash like this:
    INTERNAL ERROR on Browser End: Pipe closed during read? State may be corrupt
    System error?:: Success
    what is the message? the current thread is no AThread or there is no AThread
    in general?
    in bug 5101073 i found this explanation about AThread:
    When the call is handled to browser, the rest of Javascript to Java call will
    be delived to AThread (a Java level thread created during browser starts up).bug or feature? something like "AThread" is not visible in the threadlist-dump.
    is it realy absense and is this is a bug of mozilla for unix/linux?
    or is this message only a debug-information.
    in any case the tracing makes liveconnect unusable.
    does anybody know how to stop or avoid these messages?
    (stopping trace via runtime-options does not work)
    i.b.

    Yeah, there is
    http://java.sun.com/j2se/1.5.0/docs/guide/plugin/developer_guide/java_js.html
    but I do not understand who really takes ownership for
    netscape.javascript.JSObject
    I noticed that the traditional link seems to be dead:
    http://developer.netscape.com/docs/manuals/communicator/jsref/pkg.htm
    but there is
    http://wp.netscape.com/eng/mozilla/3.0/handbook/plugins/doc/netscape.javascript.JSObject.html
    I guess you could try to contact Sun and express how important this is to you. I note that 5101073 has zero votes and no comments.

  • Deployment of Ejb's, Applet calls from a Browser

    Hello, and thank you for taking the time to review my post....
    PII Celeron 333mHz
    256 Megs Ram
    Windows NT 4.0 Workstation (SP3)
    JDeveloper2.0(Build 343)
    Oracle 8.1.5
    Netscape 4.06
    Everything resides on the same machine.
    Problem 1: I had no trouble deploying EJB's initially. As their
    size grew, they became increasingly difficult to deploy. Long
    delays(10 mins.)were, and are still encountered. Is that
    acceptable for a minimal sized EJB? I've also noticed when my
    deployment fails, (different errors are presented on different
    occassions), it becomes impossible to deploy an EJB without first
    closing, and restarting Jdeveloper. Is that normal behavior.?
    Other times my deployment hangs when the Oracle 8i deployment is
    called. I test my IIOP connection in Jdeveloper, and it fails to
    work. I can't access the "sess_sh" from a command prompt either.
    Would you know the cause(s)? Which steps should be taken in order
    to remedy the situation..? A shutdown, and restart of the
    database?
    Problem 2: EJB1 is deployed to the database. A simple applet(with
    the standalone option) is created. It calls EJB1 from within
    Jdeveloper without trouble. Though when i attempt to run the
    applet via the provided HTML file, it fails. The HTML file brings
    up the appletviewer, which stalls after the applet is started. Is
    an invalid "archive" file provided in the applet tag? Which
    ".jar" file should be present..the *Generated.jar file?
    With regards to running the applet in Netscape, it fails. When i
    deploy the ejb, should i include the "java40.jar" file as a
    dependancy..? Should the "applet.class" file be included in the
    deployment as well.? Should the typical Jdeveloper classes be
    also stored in the ..Netscape\Program\java\classes directory?
    Would someone be able to provide me with a simple applet, ejb
    scenario, stating which .jar files are needed, and where they
    should be present etc..?
    My thanks in advance :)

    Hey Mark,
    Maybe you can help then, I am getting the below errors (I am
    pasting in a message I wrote earlier):
    Hello,
    I think I got one that could stump a bunch of ya... we'll see.
    I wrote an EJB in JDev. 2.0 and deployed it. Worked well, no
    problems. Wrote a Client Snippet, worked well (never tested
    outside JDev.). Wrote a Client Applet, works very well INSIDE
    JDEV. 2.0, once I try to run it outside JDev, I get nothing but
    Exceptions.
    SO, I tried deploying it to a jar, made sure to add all the
    propper .jar and .zip files and everything. I deploy it and run
    it inside IE 5.0 (using OBJECT instead of APPLET tags with the
    right java plug in etc.), that hangs. SO i use appletviewer to
    pick up the error messages and I get the stuff below (exception
    and stack trace at end of message).
    java.naming.factory.initial (which is in the exception message)
    was new to me so I spent the last two days reading about JNDI
    etc, and found out that it is just an environment property for
    JNDI and that ORACLE does not use it once in any of its examples
    or anything.
    I have been unable to locate AURORA's version of its
    ContextFactory (I tried just about every class with the word
    Factory in it -- took forever), and none of those worked. To be
    exact I found one class that looked like it could have worked:
    oracle.aurora.jndi.sess_iiop.sess_iiopURLContextFactory.class...
    I tried that, but that returned a ClassCastException.
    So here's my synopsis: Inside JDEV for some reason the command:
    Context ic= new InitialContext(environment);
    works, as long as I specify a minimal number of environment
    properties: javax.naming.Context.URL_PKG_PREFIXES (which I set
    to, as Oracle says to do,
    oracle.aurora.jndi),Context.SECURITY_PRINCIPAL,
    Context.SECURITY_CREDENTIAL, and the NO_SSL one too. That works
    fine in JDEV, throws the exception (see below) outside of JDEV.
    If then try to specifiy a context factory
    (Context.INITIAL_CONTEXT_FACTORY
    constant) of the class type above I throw the exception shown
    above inside and outside of JDEV (i.e. in appletviewer). Here's
    where it gets weird:
    If I use the above configuration that works in JDEV (no initial
    context factory environment setting) and try to print out via
    the list() method the context's bindings, I get the same
    exception that is seen below. SO the only time it works, is when
    I don't specify the initial context factory and I ONLY run it
    inside JDEV WITHOUT performing any actions on the instantiated
    context variable other than a lookup. REALLY WEIRD!
    So please help ASAP, thanks.

  • How to run applet inside a browser coz my applet runs outside the browser

    I would like to run the Java Applet viewer in-line inside a Browser Window. Presently, when launched through an html page, the applet opens another main window outside the browser. Can't seem to find any applet parameter tags for it. If there is a way to do that please let me know. Thanks in advance - m.a.

    public class mainGIS extends JApplet {

  • Unresponsive script screen pops up constantly freezing the browser

    It started when using the chat of Facebook but after also when playing it's games, that this screen "Unresponsive script" pops up constantly and the browser freezes till I click on the markers "Don't ask me again" and "Stop script"
    This started to happen when I updated Firefox because this never happened before.
    I loved Firefox but now it has become very annoying.

    Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
    * Don't make any changes on the Safe mode start window.

    lookupElement.onchange = function () { OnFormationChanged() };
    When a user select an element in the dropdownlist, "OnFormationChanged" event run an Async method who retrieve elements joined with the selected element in the dropdownlist lookup.
    This part works fine, it automatically refresh the multi lookup field but when i save my custom page I got the error :
    Value does
    not fall within expected range
    When I do alert in the OnFormationChanged, it retrieve me for example '0' in the onChange event and '3' in the Asynch event as you can see in this screenshot :
    I deduced that the save event method take a wrong result.
    For example :
    A : If I select in the lookup dropdownlist an element with no attached result in the multi lookup, I will have '0' in the "OnFormationChanged" method and '0' in the "OnQuerySucceeded" method and the multilookup will be empty.
    B : If NOW I select in the lookup dropdownlist an element with results in the multi lookup, I will have '0' in the "OnFormationChanged" method and '3' in the OnQuerySucceeded" method and the multilookup will be filled.
    But when I save the custom page I will have the error : Value does not fall within expected range as if async result was not recognized by the save button. 
    Something seems not to be set correctly.Could you give me a way to resolve this issue ?
    DkPoo.

    To close this post, I finally redefinied the save event and it works nicelly now !

  • How to secure a PL/SQL procedure that is called from the web browser

    If you have ever seen the sample document management application, and tried to download a file that was stored in the system, you are probably familiar with the apex_util.count_click URL that is used to download the file. If you copy that URL and paste it into a new browser, you will not be prompted to login to download the requested file. I'm using SSO with Apex as a partner application. How can I secure a pl/sql procedure like this to redirect to the login page before beginning the download?
    Thanks,
    Kris

    You can use the second method described here:
    http://apex.oracle.com/pls/otn/f?p=31517:15
    You would use an application process instead of pasting the procedure call in the browser. In the case I describe, you don't need to grant execute to public on the download procedure.

  • Applet window goes behind the browser

    Hi Experts,
    Pls suggest me the solution for the problem with applet.
    When I launch the application from browser by providing URL( we are using http server), it launches the application as an Applet . Now my problem is this applet goes behind the browser when I launch this in WindowsXP but when I launch this in Solaris it works fine.
    I want the applet to be shown in front in WinXP as well.
    Can anyone pls suggest solution for this??
    Thanks,
    Joe

    "painting behind" problems generally indicate a mixing of awt and swing components (a definite no-no).
    but this is applet behind browser, not components behind other components,
    so perhaps the problem might be better suited to the applet forum
