Applet and parameters encoding

HI everyone. I decided to post this hoping that someone will explain me how internationalization works in java so I and other people can benifit from this.
For last five days I have done a bit of reaserch on Java Internationalization. I've read tuturials that Sun provides and searched java Furums for various question. So far I have gain a lot. Now I have this question and I can not find the answer.
I understand that String is always in UNICODE. The problem I have is this
Imagine html page that is encoded in Western european(ISO).
The applet is located on this page and it tries to read parametes
The value of one parameter is in English and other in French.
The question is this. If applet reads those parameters will String contains correct Unicode format. If I will try to display these strings in label will french be displayed correctly. ?
second question applies to Japanese. will applet read japanese values of parameters correctly?
Basically I want to now how java handle language in this situation
Thanks

I found the problem it was related to "value" of parameter in HTML file ,I must set a specific value instead of "" in html tag like the following :
<param name="Field" value="1">

  • Signed applet and HTML parameters

    I've created a signed applet and everything works fine, except for the fact that i can't add parameters to the applet.
    Without the parameters in the HTML the applet inits and starts and can be used without problems. But when I add paramaters, the applet reports a "class not found exception".
    I used HTML-converter to convert the applet tag to object/embed tags.
    Has anyone had the same problem or knows what I'm doing wrong? I'd really appreciate some help.
    Thanks in advance,
    Erik

  • I'm crazy!Applet and JNA Error:Library 'jnidispatch' was not found!

    Hi all,
    sorry to bother you, I really have no idea how to do JNA and Applet. I'm hardly mazy, man.
    Every time it will throw an error to me :

    Can any one help me? Thank you very much!!!!

    Hi AndrewThompson64:
    Did you mean the JNA project? Or are you refering to JNI, or ..something else?Yes, I mean is that I wanna jna.jar to replace JNI to code with Applet. I want Applet can run native library(.dll files).
    That reads like so much nonsense to me.Sorry fo that.
    Was there any 'caused by' part that you trimmed? I expected to see something to do with 'Security' or 'AccessControl'.Sorry, I can't saw any 'cause by' subsentence there. This message is just gain from Applet Console.(Is there any method to gain more message?)
    About 'Security' and 'AccessControl' I just modify my java.policy file to allpermission. Subsequently, I signed all jar files.
    For now I have 3 jar files(all have been signed ):
    --example.jar :  for this little program.(code include applet and application entry)
    --jna.jar
    --win32-x86.jar : include kernel32.dll and jnidispatch.dll for win32 and x86.
    and 2 JNLP files:
    --JNAApplet.jnlp the entry is JNAApplet.class (this jnlp does not work)
    --JNAApp.jnlp     the entry is JNAApp.class  (this jnlp works)
    And for now new error message show like this:
    Exception in thread "thread applet-JNAApplet-1" java.lang.UnsatisfiedLinkError: Library 'Kernel32' was not found by class loader sun.plugin2.applet.JNLP2ClassLoader@4aeb52

         at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
         at java.lang.Thread.run(Unknown Source)
    Did you mean invoke?
    Revoke: To annul by withdrawing.
    Invoke: To call on.Yes, you got it. Thank you.
    The JNLP file is invalid. ..I was about to put my 'standard' text here, but I'm sick of saying it. Search the forum for my posts - 50% of them, at least, mention validation and how to go about it.
    Also, the applet-desc requires a documentbase.Thank you, I really think I have some invalid section. But I can't find it, and you said 'Search the forum for my posts - 50% of them...' , I can read the JNLP structure on site of sun and I can to read you post too(I'm doing like this).*I only want to know about how to load "native lib like *.dll" properly*.
    What 'officer site'?I mean jna project site. Sorry for ambiguity.
    Please fix that sticky '!' key. One '!' indicates astonishment, while two or more typically indicates a bozo. Thanks for your advice. Because I tried to find solution do my best lasting two days. I got nothing. I'm sadness.
    here post my new files:

  • Where are Java Preferences (Applet Runtime Parameters) saved on Mac OS X?

    Hi.
    If you want to modify the Applet Runtime parameters in Mac OS X, you need to use the "Java Preferences" application located under /Applications/Utilities.
    Suppose that I open the "Java Preferences" application, I select a specific JRE version, and I set a runtime parameter of "-Xmx300m" for Applets, in order to increase the max heap size.
    Now, where is this setting saved to?
    Until recent past, these values used to be saved in the <UserHome>/Library/Caches/Java/deployment.properties file.
    But this does not seem to be the case any longer.
    Does anyone knows where are these settings currently saved in Mac OS X? I am currently running Mac OS X v10.5.8 with Java 1.6.0_20 installed.
    Any help / hint would be greatly appreciated.
    Thanks,
    Marco.

    Check this out:
    http://developer.apple.com/documentation/Java/Conceptual/Java141Development/Core_APIs/chapter_6_section_3.html
    Hopefully that all fits on one line. Click around that website for just about any Mac-specific info you'll ever need.

  • Applet and JMS

    Hello, i have a problem with an Applet. I want to connect to the JMS on a the J2EE server that is packaged with the jsdkee(SunOne?).
    I use the following code
        env = new Hashtable();
        env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.cosnaming.CNCtxFactory");
        env.put(Context.PROVIDER_URL,           "iiop://localhost:3700");
        try
          ic = new InitialContext(env);
          jmsFactory = (TopicConnectionFactory)ic.lookup("jms/PS/playerTopicFactory");
        catch(NamingException ne) {System.err.println("NamingException in LocalAccount.initMyConnectionFactory(): "+ne);}I get the following error
    NamingException in LocalAccount.initMyConnectionFactory(): javax.naming.NameNotFoundException [Root exception is org.omg.CosNaming.NamingContextPackage.NotFound: IDL:omg.org/CosNaming/NamingContext/NotFound:1.0]Does that mean that he can't access the Class? But i dont want to put rt.jar (including CNCtxFactory) into the applet! Maybe I misunderstand something...
    Please help me I can't figure this out

    8.1 provides a "thin client" jar. See the "new JMS features" in the
              8.1 release notes.
              For previous WL versions, check out the
              "Small Footprint Client Options for BEA WebLogic Server" white-paper
              available on dev2dev.bea.com.
              Note that if you choose not to use JMS, you can use the JDK's
              built-in IIOP client, where 0 (zero, nada, no) WebLogic classes
              are required in the client. (rmi-iiop newsgroup for details).

  • Decompile applet and proxify all URL and socket connection and recompile

    Hi,
    Please anybody have idea for the below.
    I need to decomple the applet class file to .java file and need to change all URL and Socket connection to proxify all connections from applet. and recompile the sample applet to make ready to load in browser.
    Thi is to load the applet form the web server through one proxy server. In the proxy server side While loading the applet from web server that applet code need to be changed to modify the URL and connections used in that applet to change the further connection from applet through proxyserver.
    Compile and decompile is not a problem that i can use javac and javap respectively.
    But I want to know how to change all URL and connection in applet. is there any easy way to handle this with out changing the applet code.
    can Anybody help me.
    Thanks and Regards,
    Shiban.

    Not sure how you do that:
    Client <----[HTTPS]-----> Secure Gateway <------[HTTP]------->Web servers
    or
    Internet Explorer/Mozilla <----[HTTPS]-----> proxy <------[HTTP]-------> Google
    Is the above correct?
    If so than what are the proxy settings in IE/Moz, I can specify the proxy address in the
    browsers but not the proxy type (SSL).
    When you want to visit a page like google I gues you just type http://www.google.com in
    the browsers address bar. The browser will figure out how to connect to the proxy.
    Java has got the control panel in the general tabl there is a button "network settings...:"
    I have it to "use browser settings" and this works for me.
    All URL and URLConnections work but the sockets don't (maybe put in a bug report)
    for example games.yahoo.com -> card games -> bridge -> create table
    In the trace I can see:
    network: Connecting http://yog70.games.scd.yahoo.com/yog/y/b/us-t1.ldict with proxy=HTTP @ myproxy/00.00.00.00:80
    network: Connecting socket://yog70.games.scd.yahoo.com:11999 with proxy=DIRECT
    The second one fails because port 11999 is not open (what idiot uses an unassigned
    port for a profesional site is beyond me).
    http://www.iana.org/assignments/port-numbers
    #               11968-11999 Unassiged
    Even if the port was open on the proxy you'll notice with proxy=DIRECT that
    "use browser settings" does not work with socket (bug report??).
    Anyway my advice is to open the java console (windows control panel or javacpl.exe in
    the bin dir of java.home) and make sure it is set to "use browser settings"
    Then enable a full trace:
    To turn the full trace on (windows) you can start the java console, to be found here:
    C:\Program Files\Java\j2re1.4...\bin\jpicpl32.exe
    In the advanced tab you can fill in something for runtime parameters fill in this:
    -Djavaplugin.trace=true -Djavaplugin.trace.option=basic|net|security|ext|liveconnect
    if you cannot start the java console check here:
    C:\Documents and Settings\userName\Application Data\Sun\Java\Deployment\deployment.properties
    I think for linux this is somewhere in youruserdir/java (hidden directory)
    add or change the following line:
    javaplugin.jre.params=-Djavaplugin.trace\=true -Djavaplugin.trace.option\=basic|net|security|ext|liveconnect
    for 1.5:
    deployment.javapi.jre.1.5.0.args=-Djavaplugin.trace\=true -Djavaplugin.trace.option\=basic|net|security|ext|liveconnect
    The trace is here:
    C:\Documents and Settings\your user\Application Data\Sun\Java\Deployment\log\plugin...log
    I think for linux this is somewhere in youruserdir/java (hidden directory)
    Print out the full trace of the exception:
    try{...}catch(Exception e){e.printStackTrace();}

  • IIS, Javascript, Signed Applet and ASP Blank Page Problem

    Hi,
    I'm having a problem using a Signed Applet in a site that runs in a IIS (Windows Server 2003).
    My aspx web page uses the applet to read my smart card and get information from it.
    This applet uses an auxiliar dll (stored in a second Signed Jar file) in order to read the information from my smart card.
    The way the solution is design:
    1) Aspx page is asked from server
    2) Internet Explorer recieve the page and asks the server for it content (images, applet, javascripts, etc)
    3) After this the JVM runs (console opens)
    4) After the Aspx page render fully a javascript register onload fires and call an applet method
    5) Applet receive the call and run the logic of the method:
         - reads the smart card;
         - calls Javascript function in order to fill aspx fields with information from smart card
         - calls Javascript function the simulates a click in a botton of aspx page (in order to call server side part sending data readed from smart card to server)
    5) The server makes some logic with the information receive and responds to client registering in aspx page a call to another Javascrit function
    6) The client received the asnwer from server and runs the Javascript function registered on step 5)
         This Javascript calls another method from applet and runs the following logic:
         - reads more information from smart card;
         - call javascript function in order to fill more fields of aspx page with the information readed
         - calls Javascript function the simulates a click in a botton of aspx page (in order to call server side part sending data readed from smart card to server)
    7) The server makes some logic and call another pages with no Applets
    8) Client asks for a second page with the same applet and we start with another logic express on steps 1);2);3),4);5) and then 7).
    This is all ok, until sometimes the server stop responding correcly for requests regarding this two pages with the Applet.
    When this happens the server just responds with a blank page.
         - with fiddler I can seer the request for the aspx page (that uses the applet)
         - but server responds with a blank html page
    The JVM doesn't fire.
    The IIS log don't show errors.
    The eventviewer doesn't show errors.
    The problem is solved with an IIS reset or a Application Pool reset.
    After a while the problem returns.
    This problem occours for other user in another machine, the server just stops responding correcly to request regarding pages with applets, the other pages still continue to work.
    If we disable Java Control Panel->Advanced->Java Plug-in->Enable the next-generation Java Plug-in the problem seend to stop, but we can't force all clients to disable this option right?
    Or there is a way to force the Applet to run with this option disabled?
    As anyone experience similar problem?
    Regards,
    OF

    This is all ok, until sometimes the server stop responding correcly for requests regarding this two pages with the Applet.
    When this happens the server just responds with a blank page.
    - with fiddler I can seer the request for the aspx page (that uses the applet)
    - but server responds with a blank html pageWell, if http requests look identical in case of success and failure (pay attention to cookies, etc) then it has to be something on the server side.
    It could be that server gets into this wrong state because of previous requests made by applet but it is hard to tell.
    I am not clear how old/new plugin can make a difference unless your applets run in the legacy mode (i.e. you are actually trying to reuse SAME instance of the applet when
    it is loaded next time).
    I'd start with
    1) carefully comparing good/bad sessions
    2) checking whether server will serve correct response to another client when it serves "bad" page for current client
    3) add debug statements to aspx - it is scripted page, may be some condition is not met and then it returns blank?
    4) record all http requests in one session until you get to "error" state and then use any http server testing tool to "replay" this set of requests.
    You should be able to get server into the same state without use of applet. Then you can try to tweak set of requests to see what makes a difference.

  • Problems installing Bridge and Media Encoder in CS6

    I recently installed Creative Suite CS6 Design & Web Premium. I had previously installed the CS5 version and had not un-installed it. Everything except Acrobat appeared to install correctly. When I opened Photoshop CS6 (64-bit) I noticed that it used the CS5 version Bridge. I went into Bridge and unchecked the open at start box, closed Bridge and Photoshop and re-opened Photoshop CS6 (64-bit). When I tried to lunch Bridge from Photoshop the following message appeared in the Desktop> panel : Waiting for Bridge CS6..." Bridge CS6 did not appear despite waiting for several minutes. I then pressed the Start button and went into the Programs listing. Under the Adobe CS6 group I found all of the applications (other than Acrobat) but Bridge CS6 (64-bit), Bridge CS6, and Media Encoder each had generic icons rather than the expected relevant Adobe icons. I tried to load each of the three by clicking on the icon. In each instance the following message appeared:
    The version of this file is not compatible with the version of Windows you are running. Check your computer's system information to see whether you need an x86 (32-bit) or x64 (64-bit) version of the program and then contact the software publisher.
    My system is a Gateway FX6802. I am running Windows 7 Home Premium version 6.1.7601, Service Pack 1, Build 7601. The system has 9 GB of memory. I ran CS5 on the system and did not experience any difficulty with Bridge.

    Thanks. Being the impatient sort (inspite of the problems that can create) I only did a partial uninstall with the cleaner tool, taking out the three items that were not working. Initially that seemed not to work. As I had other non-Adobe projects to take care of I put it out of mind. I even let an updatee package do its wonders. Today I used Photoshop for a quick project. I clicked on the Launch Bridge button and lo and behold the proper icon showed up and Bridge loaded. After finishing my project I closed down Photoshop and Bridge and then went through updating once more. The other problem I was having was with Acrobat. I finally traced the problem to a bad installation of Acrobat 9 at the CS4 level. (Shows you how much I use Acrobat.) I used the cleaner tool to clean up the remnants of CS4. After that Acrobat X installed quite nicely. At this point everything seems to be working as it should. Thanks for your help.

  • Custom Data Processing Extension and Parameters

    Hello,
    I have successfully implemented a custom data processing extension. Now I'm trying to add parameters, but the documentation is very weak on this topic. Also all examples of custam data processing extensions I have found so far are working without parameter support. Using a search engine I have found a custom data processing extension's sequence diagram during report execution. The related article also gives some hints about the IDbCommandAnalysis interface.
    The GetParameters implementation creates a parameter collection based on the current command text and returns this collection. So far no problem.
    My question is how to implement the IDbCommand's CreateParameter method and Parameters property? In CreateParameter I just return a new instance of my IDataParameter implementation, and the Parameters property returns a new parameter collection based on the current command text.
    Is this ok so? At least this is the first implementation which seems to work in the data designer. If I share an instance variable for GetParameters and Parameters I will either get all parameters twice or BIDS will crash when pressing the execute button in the dataset designer - depending on my actual implementation.
    What I'm still missing is how to get the parameters added automaticall to the dataset's properties parameter register?
    thanx in advance and kind regards, Gerald

    I think that finally (after some days of trying) I could make it work. The dataset and report parameters are reflecting the command text's parameters now (BTW: to answer my last question - the dataset's properties are updated after pressing the refresh button only). The road to success was not to use the same member variable for the collections returned by IDbCommandAnalysis:GetParameters() and IDbCommand:Parameter and not to fill the latter one with the command text's parameters (see partial source code below).
    public sealed class MyCommand : IDbCommand, IDbCommandAnalysis  
        private string m_commandText;  
        private MyParameterCollection m_parameters = new MyParameterCollection();  
        public string CommandText  
            get { return this.m_commandText; }  
            set { SetCommandText(value); }  
        public IDataParameterCollection Parameters  
            get { return m_parameters; }  
        public IDataParameter CreateParameter()  
            return new MyParameter();  
        public IDataParameterCollection GetParameters()  
            return GetParameterCollection();  
        private void SetCommandText(string commandText)  
            m_commandText = commandText;  
        private MyParameterCollection GetParameterCollection()  
            // ... create parameter collection based on m_commandText  
    Still there are some open questions:
    How can I update the report parameter's properties? Now the parameter's data type is always string, but I'd like to assign the right data type. I'd also like to tag the parameters as hidden and supply a non-queried default value. Is this possible? How?
    Although I my implementation of IDbCommandAnalysis:GetParameters() returns a collection containing the parameter names and values the "prompt query parameters" dialog (after pressing the query designer's execute button in the toolbar) shows a "<blank>" value for the parameters. What could be the problem?
    Thanx in advance and regards,
    Gerald

    You can take the parameters to the select so that you will be able to create conditions over them.
    Try to use this SQL instead of your and in the discoverer workbook create the conditions and parameters:

  • I need help with Applets and Multithreading

    [hello all.  first time poster. big fan of java.]
    now to the important matter: Applets and Threads
    =======================================
    1) I have an applet with that implements the runnable interface, and has one thread (and a simple animation). If I try to view this applet in the applet viewer with JGrasp, it spits an insane error telling me
    "java.security.AccessControlException: access denied (java.lang.RuntimePermission modifyThreadGroup)"
    but, if I run the applet through a web browser, by putting it in an html document, it runs correctly, without error
    What on earth is wrong, and how do I fix it?!?
    2) I want to put 2 threads in my applet?
    If I implement the Runnable interface, I can only have one Run() method in my applet, right?
    So how do I define behaviour for 2 threads when I only have one run method in which to define the behaviour? Can I use two threads with the runnable interface, or do I have to make objects of my own defined thread classes?
    3) I tried to make 2 threads in my applet by creating my own thread classes, and instantiating them in my applet (instead of implementing the runnable interface).
    I still get the same insane error as I mentioned in my first point (which I expected), except now, the applet won't work even when viewed through a web browser!!
    Please please help me. I am frustrated beyond belief (at what is probably a very simple problem)
    I have searched and searched all over and found no answers on this

    If I try to view this applet in the applet viewer with JGrasp, it spits an insane error telling me
    "java.security.AccessControlException: access denied (java.lang.RuntimePermission modifyThreadGroup)"Don't know anything about JGrasp, but it runs with pretty tight security - thats what this insane error is all about. Use the appletviewer or a browser.
    If I implement the Runnable interface, I can only have one Run() method in my applet, right?Correct
    So how do I define behaviour for 2 threads when I only have one run method in which to define the behaviour?
    Can I use two threads with the runnable interface, or do I have to make objects of my own defined thread classes?You can create two Runnable implementations (classes) in your applet.
    example (missing code)
    class MyApplet extends Applet {
      void doSomething() {
      void doSomethingElse() {
      void startThreads() {
        Thread t = new Thread(new Runnable() { public void run() { doSomething();}});
        t.start();
        t = new Thread(new Runnable2());
        t.start();
      class Runnable2 implements Runnable {
         public void run() {
           doSomethingElse();
    }If the above seems confusing, read up on anonymous and inner classes.
    3) I tried to make 2 threads in my applet by creating my own thread classesTry not subclassing thread - this causes a security check

  • Socket communication failure between Java applet and C++ application

    I have a java applet that connects to a C++ application via Java's ServerSocket and Socket objects. THe C++ application is using the Winsock 2 API. The applet and application are running on an NT workstation (SP 6) and using IE (5.5) For a very simple C++ test applications the communictions work fine. Once more code gets added to the C++ application the portion of the socket that C++ listens to seems to close. Upon performing a recv call the return value is a zero. Microsoft insists this is a sign the Java side has shut down the socket. The Java applet can still receive messages from the C++ app but C++ cannot receive responses from the Java side. Java throws no exceptions and an explicit check of the socket shows no errors. Again, what puzzles me is that it works for simple C++ applications. Are there any known conflicts between Java and C++ in this regard?
    I have inlcuded the basic java code segments below.

            System.out.println("SendMessage : Flush - No Error");
       }

    a very simple C++ test applications the communictions work fine. Once more code gets added to the C++ application the portion of the socket that C++ listens to seems to close.
    This quite strongly implicates the extra code in the C++ App. The firstly thing I would try would be telnet. Try connecting to both versions of the C++ Application and manually reproducing a proper exchange.
    a recv call the return value is a zero. Microsoft insists this is a sign the Java side has shut down the socket.
    A correct implementation of recv should return the number of bytes received, or -1 for an error. A zero return indicates no bytes received not a socket closed/error. This sounds like FUD to me.
    Are there any known conflicts between Java and C++ in this regard?
    I can see no obvious faults, though the code is incomplete, I don't think it's an sockets implementation issue, at either end, it sounds more likely to be a protocol/handshaking bug in the C++ App.

  • Security issues with applets and windows Vista when printing to file

    Hi, everyone
    I am currently developing an application that prints out the result of some calculations.
    from a Javascript file, the output finally ends up in a java applet that should print the file in a special printer.
    For debugging purposes I have created a File printer that creates a file from the output comming to the printer; this way I can debug what commands the printer is receiving.
    This worked well on Windows Xp; Vista always asks for permissions for the applet, and altough I guarantee these permissions, printer is not allowed to create the output file and reports an error writing
    after a little research, I have found that java applets have all permissions when certificated as trusted applications; all but file creating permissions
    anyone has any idea of how could I fix this problem?
    Thanks in advance

    HI,
    Have you actually signed your applet? If the signers certificate is the trusted key store for Java it should treat your applet as trusted. You can use a self signed certificate for testing as long as the cert is in the trusted key store.
