Applets, Javascript and IE6.0 (WinXP)

I've been trying to implement Javascript to Applet communication in IE6.0 on WinXP but found that it refuses to work. Normally:
<script>
function getCountry() {
countryVal = document.countries.country.value;
alert(RegionHelper.getCountry(countryVal);
}</script>
<applet name="RegionHelper" ... MAYSCRIPT></applet>
Get Country
<form name="countries">
<input type="text" name="country">
calls the od of the applet "RegionHelper" which returns a value and displays it in a dialog box.
Running this through Netscape 6, not a problem. Try it with IE6.0 no luck!
Okay I understand this is a WinXP-No Java support problem but is it the Javascript failing or does Microsoft have an Anti-Java applet functionality built in? Aside from the fact that all new PC's are shipped with WinXP now as well, it is a real problem if I need to implement any Java functionality.
Is it worthwhile offering a link to run the applet through WebStart instead?
I've tried embed and object but neither support the 'MAYSCRIPT' attribute and using a <jsp:plugin...> refuses to accept the 'MAYSCRIPT' attribute.
Anyone have a work around at all?
I beleive N6 uses Javascript 1.5 but I'm not sure about IE6

Forget it. I found the solution in the Java-Plugin forum.

Applets, JavaScript and Internet Explorer

Hey guys
Is there any way that an applet can call javascript functions in Internet Explorer? I know it's possible in Netscape, but I've yet to come across a viable solution for Internet Explorer.
I've got an HTML page and I want the applet to be able to change the content of a certain part of the page (a marquee) every so often. It doesn't need to use a JavaScript call if you can think of a better solution, but that's the only way that I've tried so far.
A big thanks to anyone out there who can help me
Ryen

There is an easy way to change HTML code from JavaScript by calling an applet, which is not exactly what you want, but is much more simplier.
Define your applet as scriptable=true.
Within JavaScript call the method that knows the information you want to print and make it return as a String.
For example:
// JavaScript
View.innerText = myApplet.giveMeMore(); // return a string.
// The HTML View
<div id="View"></div>
You can see something like that with an Swing Applet in http://www.amicworld.com by following XmlBroker.

COMMUNICATION BETWEEN JAVASCRIPT AND JAVA APPLET: US$20 AWARD FOR SOLUTION!

COMMUNICATION BETWEEN JAVASCRIPT AND JAVA APPLET PROBLEM (Easy Filter Java Applet) -
US$20 TO ANYONE WHO CAN RESOLVE THE PROBLEM
To forum visitors:
I am prepared to pay a standard shareware fee of US$20 to a user who can resolve this technical problem.
If your advice resolves the problem, I'll forward the payment to your postal address (include your
address with your reply, and also your email address)
I am attempting to enable a HTML button (using Javascript's onClick command) to directly input a number into one of the parameter text boxes in the Easy Filter Java applet (ie, enter a new color value number in the text field of the standard Colors Multiplicator Filter interface).
The applet is Freeware and can be downloaded at: http://www.javazoom.net/applets/easyfilter10/EasyFilter10.html
(It is a very effective bitmap display and editing utility)
To achieve this, I am trying to access the part of the applet that defines and sets the textbox. The text box is defined in the .class file by accessing the parameter details in the genericfilter.txt file (accompanies the .class files). I need to access 'private String appletInitialize()' and then one of the 'textFieldParameters' which sets the textbox.
I understand the basic syntax for referencing the applet:
document.appletname.setString("An example"). However, accessing the text fields in this applet is more complex!!
Please can you recommend the correct Javascript syntax to achieve communication with the applet.
Thank you for your kind assistance.

Javascripts and applet combination not working properly in JRE1.6.0_13

Hi,
We have an applet in a JSP and that jsp also has a javascript function which is called by body onload tag,
The applet and the script works fine if the JRE on the client is JRE 1.6.0_13 (classic mode)
But the applet hangs and throws error when JRE on the client is JRE 1.6.0_13 (next generation)
Has anyone seen such issues or can give me pointer?
Any help will be appreaciated.

From the JavaDocs (http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/http/HttpServletResponse.html#sendRedirect(java.lang.String)) : This method can accept relative URLs; the servlet container must convert the relative URL to an absolute URL before sending the response to the client. If the location is relative without a leading '/' the container interprets it as relative to the current request URI. If the location is relative with a leading '/' the container interprets it as relative to the servlet container root.
So you should change it to response.sendRedirect("SecondPage") if your current request is at http://test.com/test/something

Easiest way to pass GET parameters to applet - Javascript really required??

I want to transfer GET parameters to an appelt, i.e. in the call
http://***/test.html?param1=abc&param2=def
the param/values should be available in the applet.
After some searching I've got the impression that this requires Javascript
(http://stackoverflow.com/questions/12585022/how-to-pass-values-from-html-page-to-java-applet),
but I would like to avoid this...
Any help appreciated,
Dieter

found something:
http://docs.oracle.com/javase/tutorial/deployment/applet/invokingAppletMethodsFromJavaScript.html
http://stackoverflow.com/questions/14016972/call-java-applet-function-from-javascript
and this is doing the trick, the Applet has Setters for my params
<html>
<head>
<script language="Javascript">
function readGetParams(){
   x = window.location.search.replace("?","");
   y = x.split("&");
   v1 = y[0].split("=")[1];
   v2 = y[1].split("=")[1];
   //alert( p1 + " -- " + v1 + " -- " + p2 + " -- " + v2);
   document.getElementById("fscapp").setUserID(v1);
   document.getElementById("fscapp").setCourseID(v2);
</script>

Access Custom Attributes in JavaScript and in Transactions

Hello,
I try to work with custom attributes. I've problems accessing the values in JavaScript and in transactions, but it works fine within .irpt pages.
What's the trick?
For a custom attribute called PLANT, can I write something like this in JavaScript?
var p = ;
Is there a way to access custom attributes in the Link Editor of an Action Block?
Kind Regards,
Matthias

Hi Matthias,
it is not possible to integrate that kind of MII variables in JavaScript like you discribed before.
You are right that this kind of expression is possible in the .irpt file. The reason why it is working in the .irpt
but not in the .js is, that the MII script parser is only replacing in HTML content. Everywhere you have
scripting the parser will not replace the {...} markings (since the curly brackets also show start/end of functions aso.).
Variables to JavaScript
The easiest Way to get those variables is to create hidden fields in the .irpt file that you can access via JavaScript.
For example:
<input type="hidden" id="hidden_plant" value="{PLANT}" />
This will be parsed to (e.g.)
<input type="hidden" id="hidden_plant" value="Karlsruhe/DE" />
Now you can access this value in JavaScript via:
document.getElementById( "hidden_plant" ).value;
Variables to Transactions
To parse custom variables to a transaction you first have to specify corresponding transaction variables in the
transaction itself. After saving the transaction you can map those variables to Parameters in the Xacute-Query-Editor.
Including this transaction to your webpage you can simply assign the required value to the corresponding parameter.
For example if you mapped the Plant variable of the transaction to Param.1 you can specify the information in the .irpt
like:
<applet id="trx_test" ....>
<... />
<param name="Param.1" value="{PLANT}" />
</applet>
Another possibility is to set the value dynamically via JavaScript if you use:
document.getElementById( "trx_test" ).getQueryObject().setParam( 1, "Karlsruhe/DE" );
Native access to user variables via the BLE is not possible (as far as I know).
I hope this is what you wanted to hear?
Best Regards
Sebastian

Calling a Java Applet - Javascript

Hey guys,
I'm still fairly new to Java. I'm having a hard time getting my Applet to run properly.
Basically, this is what I want it to do:
I have a web page with a series of fields on it (a form). I have a submit button. When the user clicks the submit button, it activates a Javascript function in a seperate file that validates ALL of these fields. The validation that it does is merely to determine whether or not the fields are blank.
Once it's accomplished this task, I THEN want it to run a Java applet.
Everything works up until the point at which it runs the Java applet. I'm not sure how exactly I'm supposed to call the applet from Javascript.
In every example of a web page that I see that has an applet, it has something that looks like this:
<APPLET CODE="classname.class >
</APPLET>That's all fine and good, but the problem is that it automatically calls the Applet then. I don't want it to do that. Is there a way that I can CALL the applet at the very end of a JS file? I mean, I don't want anything to load, no grey boxes or any of that stuff until I actually call it..
Any idea?
Thanks!
Todd

dude,
have you managed to call an applet method from firefox?
I'm not sure it is working at all.
I've read few articles and everyone is complaining about the same error:
Error: document.appl01 has no properties
in the case above the applet was called "appl01"
I've tried using
document.applets[0].<the applet method>
and I've got the same result..

Problem of Java - javascript and javascript - java communicate of same obje

Hi all,
I have met a great problem in program an applet! I have tried to communicate between java and javascript and javascript and java in the same page by using jsobject. However, problem occur. It is not a problem to call javascript from java by using jsobject. However, javascript call java by using document.object.function has problem. It cannot find out the object in IE. I have followed the webpage show in java, but the browser still prompt me the object called client not find. Please help!! My html code is shown as follow:

Thanks your kindly help.
Alva

Everthing looks fine to me from here, you should be able to just call the java function direct such as
document.myAppletObj.doMethod();
I think your problem could be that your object is called "client". IE can get funny about names, it didn't like me calling a method delete()!!
Try adding something else to the name such as "my_client", and see if this works any better.

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!

Communication between javascript and Objective-c in iOS.

We wanted to have a communication between javascript and objective c code. We have already tried the below approach.
To load fake URLs in JS and append a string which will be used as parameter to the Objective-C code and parse that URL in this delegate method:
-(BOOL)webView(UIWebView *)webView shouldStartLoadWithRequest(NSURLRequest *)request navigationType(UIWebViewNavigationType)navigationType
Then send the return value by calling the native method stringByEvaluatingJavaScriptFromString again with parameter callID.
But we wanted to access Objective class object in Javascript code so that we can call it's methods from javascript code using this object.Android supports this behaviour using addJavaScriptInterface method in webview. Is it possible to have the similar approach in IOS? If not what is the best approach possible to acheive this? If we could achieve similar behaviour then we don't need to change the Jacascript code and will be reused. Please suggest the best possible solution.

Using Google GWT to create (Dashcode) widgets for iBook Author I would like to embed interactive widgets in iBooks using iBookAuthor. The widgets in question started life in Java but GWT has allowed them to be converted to javascript and to run on web pa

I would like to embed interactive widgets in iBooks using iBookAuthor. The widgets in question started life in Java but GWT has allowed them to be converted to javascript and to run on web pages (for example, http://softoption.us/content/node/437 scroll to the bottom). In theory, iBookAuthor can bring in most html5, and much javascript. The technique is to wrap the html in a folder, with 2 extra files, a plist and a default png and then change the extension of the folder to ‘.wdgt’. This is the technique for making Dashboard widgets for the Mac, and Apple even have the Dashcode software to do it. So what you really do is to make a Dashboard widget, then iBookAuthor can import it. So far, so good. And some folk have been doing this, for example http://www.prweb.com/releases/2012/2/prweb9242432.htm http://www.panophoto.org/forums/viewtopic.php?f=64&t=10417&p=158330#p158423 However, if you start with GWT and create a single page with one button and a Hello World, compile it, and get the WAR file (I use Eclipse here)… the Safari browser and others will run it properly (even on an iPad). Then if you wrap it, a proper Dashboard widget is created, which runs properly on a Mac. Then if you go to iBookAuthor and put a custom widget in the Text, then drag it in. It is accepted by the text and shown as being there. However, if you use Preview to look at it on an iPad, it is gone (or was never there in the first place). Anyone any ideas on this? [And iBook Author seems to give no warnings.] The widget is at https://dl.dropbox.com/u/46713473/Test6.wdgt.zip I have bells and whistles that I’d like to get into an iBook!
Thanks for any insights.

I do have a little to add, which might help someone. Indeed, opening a blank page and dragging the widget straight in seems good in difficult cases. But, actually, I was also able to insert successfully from the Toolbar especially to blank pages. So, it may have been something to do with the columns and stuff like that. Anyway back then the insertion would show in iBooks Author but not in the Preview on the iPad. I moved on to actual Google Web Toolkit output javascript. Basically I had three at hand to try: a Hello World with a button which went straight it, one of moderate complexity, (for example with a built in Lisp interpreter), which also went straight in, and finally a more complex one that initially was rejected by iBook Author. Author complained that there was an unsupported media file (of course, Author does not tell you which one it is, that would be too easy). [Remember, this was a proper working Dashboard widget which could be installed on a Mac]. Among other things I had read remarks about .gif files. When looking through the GWT war directory at the actual javascript etc files, I noticed there were two gifs there one called ‘clear.cache.gif ‘ and a second one called ‘0F89659FF3F324AE4116F700257E32BD.cache.gif’. (Now, there is obfuscation so the numbers here may be different from case to case.) The clear.cache.gif did not seem to be anything special. But the other one is an animation. It is three little boxes that twinkle (rather like a waiting spinning cursor). So, I opened that file and saved it to itself (that picks the top frame of the animation and saves only that, leaving you with an unanimated gif). The resulting widget drags and drops into iBooks Author (and seems to work properly at a quick glance). So, if you are having trouble with ‘unsupported media files’ converting animated gifs into unanimated gifs might help in some cases.

How to find out the filename of javascript and pathname of javascript?

I got the filename of javascript and pathname of javascript(not the active document file name) using the below code in illustrator cs3.
var path = $.fileName;
But my problem was if i run the javascript through "extendscript toolkit" i got it correctly. But if i run my script through illustrator cs3 application(File->Scripts->test.jsx) i got some integer value only(did not get the javascript filepath and filename). Kindly advice how to get the javascript file name and file path in windows platform through illustrator cs3 javascript. Please help me.

I already have that extension, but I'm not sure which idx I need to look at. Also, I suppose that the numbers I'm looking for depend on places.history.expiration.transient_current_max_pages and therefore there is no way to get them relative to the installation of Firefox. My point is, I can see my history only up to 1 year, even though I have Firefox installed for 3 years. Correct me if I'm wrong.

How to disable 'Enable JavaScript' and 'Display PDF in browser' in Adobe Reader 9.1 msi?

I'd like to how to disable 'Enable JavaScript' and 'Display PDF in browser' in Adobe Reader 9.1 msi.
Any help would be appreciated.

NeoChang:
You can modify the installation package using the Adobe Customization Wizard to toggle the "Display PDF in Browser" but I have not found a setting to disable JavaScript from the Wizard. I have created a script which makes the changes, but it has to be run for every user since that info is stored in the User hive of the Windows registry.
Disable JavaScript:
REG ADD "HKCU\SOFTWARE\Adobe\Acrobat Reader\9.0\JSPrefs" /v bEnableJS /d 0 /t REG_DWORD /f
Disable Browser Integration:
REG ADD "HKCU\Software\Adobe\Acrobat Reader\9.0\Originals" /v bBrowserIntegration /d 0 /t REG_DWORD /f

Encrypt in javascript and decrypt in java

hi guys,
iam in a strange situation, my requirement is to encrypt the user entered details thr javascript and decrypt in those in java.
i need some ideas
thanku

Why don't you just use SSL? Then the entire communication is encrypted.

I know only Javascript and would like to convert a large numbers of scanned documents into layers to mount on white a4 canvas

I have got more than 400 scanned documents of A4 size. But they are not of uniform size. Luckily they are all of 300 dpi.They were created on a scanner. When opened in photoshop they contain random patches that are transparencies, although there seems to be no difficulty viewing themon adobe reader.
My laptop had "Gb RAM and does not accept CS4 I have Photoshop CS3. My javascript and photoshop are both limited to basic skills.
I would like to mount each document on a white A4 sized photoshop background of300dpi, as a layer, flatten it out and save as the desired page.
As this is rather time-consuming, I would like to have a script that will perform this task, on a single file.
I would like to manually run this script on each file.
If possible I would additionally like to put the individual pages in a folder and run the script repetetively on all files in the folder.
Any suggestions or held will be gratefully appreciated
thanks, peter
