Java Plugin ( 1.4.2_04 ) not working

I'm using Windows 98, abd Internet Explorer 6.
I've installed the JRE 1.4.2_04.
In Control Panel -> Java Plugin, I enabled the "Microsoft Internet Explorer" option (in the "Browser" tab), and "Show console" and "Show Java in system tray" ( and didn't forget to restart ).
And also, in IE , Tools -> Internet Options -> Advanced, I enabled the "Use Java 2 1.4.2_04 for <applet> " and "Java console enabled" options.
But I see no sign of either of these actions.
I don't see Java in the system tray, my applets are running on the Microsoft VM, and when I press Tools -> Sun Java Console , nothing happens! (the console window doesn't appear).
I've tried un-installing and re-installing the JRE, but it doesn't help.
Does anyone know what's the problem here?

Try using a JSP tag like I have in my post. I figured out how to have IE dynamically load the browser plugin.

Java Desktop Overview (jds-help) not working after upgrade to jdk6u1

Hello,
I am running Sol 10 11/06 for sparc on a Sun Blade. I just upgraded to jdk6u1 from jdk5. I installed all required j6 packages, and then installed patches for j6u1. Java seems to be working fine. I then used pkgrm to remove all jdk5-related packages (I searched for all packages starting with SUNWj5 and then removed them).
Now, my Desktop Overview and other java-related help functions do not work. I get this error:
# jds-help ghelp:jdsoverview
** (jdshelp:826): WARNING **: An exception occured 'Unknown CORBA exception id: 'IDL:omg.org/CORBA/COMM_FAILURE:1.0''
Maybe I removed a j5 package I shouldn't have. Which j5 packages are related to the operation of jds-help? Any ideas as to what is causing my problem with jds-help?
Thank you...

Java Plug-in 1.4 not working with IE5.5

Hi All,
I got problem loading a simple java class to IE5 using java plug-in JRE 1.4.0 beta 2.
The error message is following:
However, it works fine when I open the html page directly in the browser( i.e. use file:// instead of http://)
I'm using IE 5.5 sp 2, apache 1.3.14 for win NT 4.0 sp 6.
The page works for Netscape 4.7, but not for Netscape 6.

I checked the Proxy settings in the java plugin console, and it says "use browser settings" . I also checked the settings in the browser in "LAN settings" but there is nothing checked (there is no ip address of any proxy server), does that mean we don't use a proxy server? and I should keep on looking for another cause to the problem?
Thanks in advance

How to go back to firefox 4 lost java, plugins & acrobat in 5 firefox4 worked

firefox 4 was working just fine. I'm not sure what happened but it updated to 5 and everything quit working - Java, plugins and most annoying Adobe acrobat.
I try to watch a movie, ie weather channel, and it says I don't have acrobat so I download it and close/reopen the browser and try to watch the same movie and get the same error. I'm fed up. I want #4 back where I didn't have any problems
Improvements aren't worth the trouble if i lose the pleasure of using the program

Due to security vulnerabilities, rolling back to Firefox 4.0.1 is not recommended. Firefox 3.6.18 would be the safer choice.
Here's the process to roll back:
First, I recommend backing up your Firefox settings in case something goes wrong. See [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information]. (You can copy your entire Firefox profile folder somewhere outside of the Mozilla folder.)
Next, download and save Firefox 3.6 to your desktop for future installation. http://www.mozilla.com/firefox/all-older
Close Firefox 5.
You could install Firefox 3.6 over it (many have reported success) or you could uninstall Firefox first. If you uninstall, do not remove your personal data and settings, just the program.
Unless you have installed an incompatible add-on, Firefox 3.6 should pick up where you left off. If there are serious issues, please post back with details.
As for your registration here on the support site, I don't know how you can delete it. But in the future, just use Google to find answers like this.

Plugin: 3rd Party applets not working

I have an internally developed applet that requires us to install the Plug-In under our IE 5.5 and 6.0 browsers (about 10,000 of them). Upon doing that, I will now have a handful of 3rd party applications that employ applet technology, and that will not work with the Plugin (lots of classnotfoundexceptions being floated around). The only way that I've found I can make these applets work is to turn off use of the Sun Plugin within IE. I am wondering if this is a plugin, or vendor, problem.
* What is the basic problem here?
* Is it that these other 3rd party system are written to an older spec and the 1.4 plugin will not support them?
* Is Sun's plugin not backward compatible with older applets?
* Did these vendors screw up in some fashion in their applets or HTML?
* Is the whole idea of applets inherently flawed?
What are other folks doing to get around these incompatibilities?

I don't your exact problem with the ClassNotFoundExceptions, but it may be because those applets are using Microsoft specific APIs that caused all the lawsuits to fly.
I have had success mixing applets requiring the Java Plug-in with those that need or run best under the Microsoft JDK, as follows:
When the Java Plug-in installs, do NOT take the option that makes it the default plug-in for the browser.
In your web site:
Launch the JDK 1.4 applets with the OBJECT tag.
Launch Microsoft specific applets with the APPLET tag.

Firefox 4, Java and Mac OS X not working

I see lots of problems with JAVA not working after installing in Mac OS X. I too, cannot get Firefox 4 to work Java on any sites. It says the plugin is missing, but then cannot install it. I've tried 32 bit mode, changing Java pref's to handle things itself, but to no avail.
I am trying to open Command Center 2.0 in TD Ameritrade like I have been doing before Firefox 4.
Help!!!

You have to get the latest Java through Software Update (under the apple), and then re-install the binaries for the Java Embedded Plugin which you can find @ http://sourceforge.net/projects/javaplugin/
(read the README file for how to install)
Also go to "about:config" and set 'dom.ipc.plugins.java.enabled' to TRUE.
Not sure why all this needs to be done or why java plugin is disabled by default. Looks like something was overlooked in this last release.

</APPLET>

There are many significant errors here for instance you are using a class file as if it were an applet yet you do not subclass applet. Your code has no init method (if it is to be an applet). Your best bet is to go through the tutorials one step at a time. One thing to consider is to subclass a JPanel and draw on the jpanel overriding the paintComponent method. This can then be added to a JFrame or a JApplet's contentPane and would allow the same graphics in both. But again, please study the tutorials on all of this, otherwise you will be doing hit-or-miss programming, and that is no way to learn.
Much luck!
Addendum: Also, if you are just beginning in Java programming, I suggest you start with the basics and not with Swing / AWT / graphics programming. Otherwise you will just end up bruised and disappointed. You have to learn to walk before you can run.

Java ME SDK 3.0 not working on Windows 7 64-bit

Hi everybody,
the sdk has no 64-bit Version and the solution described at:
http://forums.sun.com/thread.jspa?threadID=5434297&tstart=45
did not work for me.
Even after changing the two configuration files bin\java and toolbar\bin\java to point to 32-bit installations of the jdk/jre, the sdk does not work and it cannot be uninstalled.
Error when starting the SDK:
A java.io.IOException exception has occurred.

When I try to uninstall, an error log file is generated in the installation path of the SDK. Although it "sees" the 32-bit java installation, at its botton appears the following (interesting?) line:

Can someone help?
Thanks a lot in advance.

Hey what's up Gatos.
Listen I have the same problem and I was wondering if you figured it out since October 2010 (your last post).
I also get the same IOException exception error. I also have windows 7 64bit, i installed 32 bit version of the SDK and uninstalled any previous versions. The Java ME SDK 3.0 Kit installed as well, and pointing to an appropriate sdk directory. I also tried changing the two configuration files (didn't have to change them because they were correct since I did not have any other version of sdk installed prior to installation of Java ME SDK 3.0.
So I am experiencing the same exact symptoms and I am wondering if you have resolved this issue yet or if you know of any other source of information that might help me. Your help would be greatly appreciated on this one. Thanks, and please respond even if it is a no if you can.
**EDIT:**
The Java ME SDK 3.0 magically started few times too, after displaying manyyyyyyy of these error windows, but it does not happen every time either. HELP

Hi,
Check whether environment variable JAVA_HOME present or not ?
If no, then set the variable with value as path of java home directory.

Java.io.File renameTo does not work on Solaris

Hi Experts,
I have a code-piece which tries to move files from one directory to another on the SAME FILE SYSTEM using java.io.File.renameTo method.
It works fine when there less no. of files in the source directory. But the renameTo does not work as expected when there are very huge no. of files(~40K) present in the source directory.
I am aware that there is a known issue when one tries to use this method to move files across file systems OR if the file exists at the destination directory.
But in my case the file system is the same and the there is no such file in the destination directory.
I suspect some inode related issues. But not sure what it is exactly.
Is there any limitations of renameTo?
Please help.

OK, we all now understand you have a problem in doing this, but without the specifics of the problem that you are experiencing, then it is fairly difficult to give you anything other than a guess. If you would like some specific and relevent answers, please supply specifics about how exactly the operation differs from your expected results. You should also post example code as it is almost always asked for eventually.

Java Discussion Forum - Post topic not working

I've deployed the Java Discussion Forum contributed by CLAURENT in Knowledge Exchange. Deployed to 10gAS in JDev 9051. I've modified a few deprecated classes and made the appropraite changes to orion-applications.xml to point to the correct JPDK jars when deployed under Linux.
The application is operating properly with no errors. The administartion portlet can modify and create new forums. However, Posting a topic does NOT work. And it doesn't throw any errors on screen or in the console log (application.log) or the log4j log (forumprovider.log). Has anyone run into a problem like this?
Thanks. LEH

I have exactly the same problem on the Portal 10g release 2.
Normally the "dit of a new topic" calls the EditPostAction but after submitting the form, nothing reachs this action.
I check this in debug mode and add several logs and I don't see nothing appearing for this action.
Did you find a solution?

Java user-defined transaction management not working correctly???

Hi everyone,
I have encountered a problem when using Java user-defined transaction management in my session bean. It threw an exception but I could not work out what that means. Could anyone comment on this? Thanks.
This BrokerBean is a stateless session calling other entities bean to perform some simple operations. There are 2 Cloudscape databases in use. Invoices (EB) use InvoiceDB and all the other EBs use StockDB.
If I comment out the user-defined transaction management code, then everything works fine. Or if I comment out the Invoices EB code, it is fine as well. It seemed to me that there is something wrong in transaction management when dealing with distributed databases.
--------------- source code ----------------------
public void CreateInvoices(int sub_accno) {
try {
utx = context.getUserTransaction();
utx.begin();
SubAcc subAcc = subAccHome.findByPrimaryKey(new SubAccPK(sub_accno));
String sub_name = subAcc.getSubName();
String sub_address = subAcc.getSubAddress();
Collection c = stockTransHome.findBySubAccno(sub_accno);
Iterator i = c.iterator();
ArrayList a = new ArrayList();

StockTrans stockTrans = (StockTrans)i.next();

Invoices invoices = invoicesHome.create(sub_accno, sub_name, sub_address, trans_id, stock_id, tran_type, price);
stockTrans = stockTransHome.findByPrimaryKey(new StockTransPK(trans_id));
stockTrans.remove();
utx.commit();
utx = null;

Three things:
first, maybe you should think of putting ut.begin() just before the invoicesHome.create() method and ut.commit() just after the stockTrans.remove() method.It wont solve the current problem but will help in performance once the problem is solved.
second, your utx.commit() is outside the try block. how come the code is compiling then??
third, try doing a SOP call before and after invoicesHome.create() method and see where the problem actually lies.
let us know...
Hi SteveW2,
Thanks for being so helpful. Here are my replies:
Can I just ask why you're not using containermanaged
transactions?The reason why I didn't use container managed
transactions is because I don't really know how to do
that. I am more familiar with this user-defined
transaction handling.
I have attempted to implement the same method in an
entity bean and just let the container manage the
rollback itself. The same exception was thrown when
running the client.
Also, the transaction behaviour is likely to relateto
the app server youre using - which is it?What do you mean by the app server? I am using J2EE
1.3.1 if that is what you meant.
Finally, if your code has a problem rolling back,and
throws an exception, you discard your exception
thereby losing useful information.I have tried to print the exception stack as well, but
it is the same as just printing the general
exception.
This problem is very strange cause if I comment out
the transaction management thing, then everything
works fine. Or if I am only working with 1 single
database, with this user-defined transaction handling,
everything works fine as well.
Here is the error log from J2EE server if you are
interested.

What is "connection previously closed, open another

I'll keep trying till I solve the problem.

Downloaded air/flash/java(??) software suddenly not working.

I play online poker professionally and for a living, and everything has been running fine.
Then today, my SkyPoker app suddenly started timing out at the table and becoming very laggy and skippy.
I have argued with the Sky support team but they're convinced it is my error. My internet connection is fine so it's not that, and if i log in on a Windows laptop it works fine.
So i opened up Betfair Poker on the desktop and that is nowhere near as bad but is still not running smoothly at all.
To my knowledge no updates were installed before it started running like this. My Safari also seems to be pretty laggy at the moment.
I know NOTHING about computers or macs whatsoever, so i don't even know if they run on Java, Flash, Adobe AIR (which is had to download to install SkyPoker) but this mac is only 6 months old so wouldn't expect this out of it.
I need to know how to check what's causing the problem or how to fix it but i have no idea where to start. I thought it was Sky's problem but as it seems to be happening on all these kinds of software i'm thinking it's definitely a problem with my mac.
I'm running Lion 10.7.4 and have all the latest updates for Java, Adobe Air, Adobe Flash and the latest actual software for the programs i want to use installed. I even tried uninstalling then reinstalling them manually.
The last software update updated Safari and the Raw Camera Compatability Update, but these were updated after the problems started.
Any help is appreciated because i'm pulling my hair out and cannot continue with these problems on what has otherwise been an awesome first mac experience for me. I don't really want to have to send my mac off to be looked at by someone either.
Cheers, Phil.
PS Apologies if this is in the wrong section but i didn't know where to put it.

You should be aware that this is a forum for discussion for Java developers. It is not an end user support forum.
At any rate your issue is a problem with the site in question. "java.lang.NoClassDefFoundError: PChatPanel" means that resources the program needs cannot be found. This is a problem with that site and you will have to address it with them in order to resolve it. Nobody else can help you with this because it is a site problem and beyond our control.

Juniper Java Secure Application Manager does not work with Snow Leopard

Anyone else having issues as well? I'm not using a client - its basically the Java based application manager for VPN connections to work (so I can remote desktop to my work PC).
Once logged in, it gives a "Restart your browser" error.
Thanks for your help

OK - so I got it to work. Here's what I did. Let me know if it works for you:
I wasn't able to follow the instructions exactly as noted in the original link I posted above.
The terminal command, specifically wget would not work - there is no wget.
I manually downloaded the Java 1.5 version, by following the link (just clicked on it). I 'unzipped' it and moved it into the library/frameworks/JavaVM.framework/versions folder.
So now the 1.5.0 is not an alias (as it is by default in SL), but the older version of Java.
I then followed the instruction related to changing the order in JAVA PREFERENCES.
The final stop - and I think this is key, is that I forced Safari to start in 32 bit mode. You can do this by going to Applications, highlighting Safari and hitting CMD-I. Then check the 32 bit option.
Start Safari, go to the appropriate URL and login. The Java Secure Application Manager should then start as it used to do in Leopard. You should be all set.
Hope this helps - let me know if someone has questions.
