Java appl to browser

Pls Help!!
From my Java application I have launched a browser window displaying a HTML page. The page have a text field with the cursor in it. Now from my Java application I would like to enter value in the text field. In other words, I don't want to type data directly into the HTML page text field. How do I do that?
I am using Windows 2000 machine.

Hi.
I've heard smth like that, but it was in the applet. You have to add id attribute to Your text field in the html (example: <form type="text_field" id="my_text_field_id">) or something similar). Then, in the applet, You can get acces to this text field like to object: Document.your_text_field_id. This text field in DOM model has for sure a field like value or text, and then You can simply set the value for this attribute. So I propose go into this direction.

Problem in display file in java applet embeded browser

hi, i am facing problem to display the file from local drive in java applet embeded browser. here is the error message i get:
Exception loading file from path:java.security.AccessControlException: access denied (java.util.PropertyPermission user.dir read)
i think it should be the java security problem and i have try to get the solution from internet. i try to solve by using the fllowing method:
keytool -genkey -keyalg rsa -alias yourkey
keytool -export -alias yourkey -file yourcert.crt
javac yourapplet.java
jar cvf yourapplet.jar yourapplet.class
jarsigner yourapplet.jar yourkey
but the command prompt ask me to enter the keystore password. i try to enter any password. but i show me the error:
keytool error: java.io.IOException: Keystore was tampered with, or password was incorrect.
So may i know what is the problem actually?Thanks a lot.

Two issues: Mail dotcom is now telling me to enable java in my browser and firefox has issues w/duckduckgo search engine. I am not allowed 2 instal DDG n search

2 issues: After a windows update on 5 10 2012, maildotcom says I need to enable java in my browser, when as far as I can tell, it is.
Second issue is, I am not able to add duckduckgo as my preferred search engine. I get a pop up in search tool add-ons that says "sorry, you need a Mozilla based browser to install a search plug in."
Why and how can these irritations be fixed?

*To add a site to the NoScript "whitelist" ('''always allow''') --> when on the site, click the NoScript icon and choose "Allow ''site''"; the site will be placed on the NoScript Options > Whitelist (non-italicized).

Displaying Arabic URL in a JAVA CODED WEB BROWSER

Hello everyone,
Please if there is anyone who can help me with Java Code....I have a java coded web browser, but i would like to enable Arabic .... currently, when arabic is typed into the URL bar, it appears at 'square boxes'...i would like example code on how to remedy that problem, so that when a user enters a url in arabic it displays the correct characters...Also, is there a simple code to check the 'hostname' (basically the name entered in the URL bar) whether or not it is in Arabic or not....
Mucho Gracias in advance, any help would be More than appreciated...
thanks ....
email:[email protected]

I thought it is possible to treat it like JTextArea where a user
can type in unicode characters....however on IE you can type in arabic (after the keyboard shift CTRL or ALT shift)in the URL bar...however in my little browser you cannot do that....is there anyway to enable that to happen...
once again thanks in advance....
oh and for the string check, is there something like :
host.equalsIgnoreCase('to any unicode characters');
i tried it using \u06xx but to no avail....
please any help!! id appreciate it....

Cannot enable java content in browser

I am trying to enable Java content in browser. Java version 7 update 45
In system preferences, Java, Security. The checkbox "enable java content in browser" is unchecked. When I check the box, I am prompted for admin password. After entering the password the checkbox immediately becomes unchecked again.
How can this be fixed?

Yes, I had tried most of those things prior to my original posting. Using Safe mode was something I hadn't tried in the past and was hoping that would be the fix.
I think somewhere on the machine is plist or config file that is preventing the problem from being fixed.
Thank you very much for your help.

OS 10.9 java control panel refuses to enable Java content in browser

I have a hard time to run java in any of my browsers.
The obvious place I started looking to enable Java is the java control pannel, but, when I enable Java content in the browser, and after providing an admin password, the checkboxs unsets itself as if nothing happened. Indeed... java is still not enabled and "missing plugin is shown"
Java Version 7 Update 45 was previously installed, and re-installing it does not help.

Re indexing issues in Apple Loop Browser (LP 9.0.2 / OSX 10.6.1 / Digi 002r

I'm trying to re index my loop browser in LP9 / OSX10.6.1
Are you having the same problem?
After trashing the 'Apple Loop Index', I pull in a folder from an external drive and notice that previous folders added to my browser have gone, including Jam Packs.
Also, I can't find the 're-index' option within the loop browser search option (right click brings down a list but the re-index option isn't there)
Interested to see whet you find.

Yep, I also had issues, where indexing the LP8 way (dragging folders with loops from the Finder onto the Logic loop browser) just bluffed to work (I dropped the folder on the LB, a progress window appeared, things apparently got done, but then nothing, no new entries in the Loop Browser.
So it seems that it is a L9 problem, since our Macs' are different in every aspect (Me: PPC- you: Intel, me: Leopard- you: Snow Leopard).
I finally decided to put all my loops in their default install locations and reindex them from there:
*Library/Audio/Apple Loops/Apple:*
Jam Pack 4 - Symphony Orchestra
Jam Pack Voices
Jam Pack World Music
*Library/Audio/Apple Loops/iLife Sound Effects:*
(13 folders)
*Library/Audio/Apple Loops/User Loops:*
(some folders with my own and 3rd party Loops)
*Library/Application Support/Garageband/Apple Loops:*
Apple Loops for Garageband
Jam Pack 3- Rythm Section
for thorough reindexing, here are the steps:
1. Quit Logic and/or any other app that uses Apple Loops.
2. Go to all the locations I pointed out and trash all the index files from the *Apple Loops Index* folders. Also check the same locations in your Users/'you'/Library folder.
3. Start Logic with a new empty project, open the loop browser window by hitting the o key. Now drag the folders mentioned above in bold onto your loop browser. Logic should now index them correctly, including the foldermenu !http://farm3.static.flickr.com/2743/4085966954bf4fc039d7o.png! in the loop browser.
regards, Erik.

Forms 10g - Solaris 10 Sparc and Mozilla 1.7 - Error Applicatio/x-java-appl

This page contains information of a type ( Applicatio/x-java-applet-version=1.4.2_06) that can be viewed with the appropriate plug-in
I have an application running and on windows and its is working fine with IE. but when i try to run the application of sun solaris 10 sparc machine with Mozilla 1.7 i get this error.
What can be the reason and if any body has solved this issue ? please guide me .
URGENT

I wouldn't say you made a "mistake". It might be a custom build, but Firefox never had a 1.7 version; skipped from 1.5 to 2.0 in release version numbering.
The old Mozilla Application Suite had 1.7 as its' last version produced; ended with 1.7.13 in April 2006. That's why I equate "Mozilla web browser (1.7)" with the old Mozilla Suite and not with Firefox.
http://en.wikipedia.org/wiki/Mozilla_Application_Suite
Whatever the case, no one should be using a web browser that was produced back in 2006 on the internet in 2014. If that is used completely on an internal intranet, you shouldn't have a problem; beyond finding support for an old version like that.

Java applet in browser

When i try to put my new applet in an browser, i get errors like can't find List.class and so on, some of the things from java.util the user interface is made in pure awt. Any idea how to solv this, when i lunch from jbuilder it works.

The Collection classes (of which List is a part) are available only since jdk1.2
Most browsers do not have built-in support for jdk1.2+
If you want to use the new classes, you need to:
1. Get the JRE1.3
2. Run your html page through HTMLConverter
