Java blocked in Win XP?

I have a WinXP Pro machine here that ran java applets fine.
Then someone installed the latest XP update to it, and the installation reported that it removed Java.
Both the Microsoft VM and the Sun Java plugin options on IE's Internet Options > Advanced tab are missing.
All attempts to re-install the JVM to Internet Explorer through the auto-installer still doesn't bring it back.
Attempts to install it on Mozilla end in a failed installation.
We're wondering if the latest WinXP update not only removes Java, but also blocks?
Does anyone know about this situation and how to resolve it?

Hi r.fox,
Your not alone. Our e-commerce system uses Java applets and several of our customers have had problems with Java since updating windows (mostly Win 2K and XP).
If the MS JVM has been removed, (type 'jview' into a command window to test if it's installed). then it's not easy to find the re-install files as they are not available from Microsoft (although I have a copy if you need them).
There has been a few different levels of problems some machines have lost Java completely. Some just database connections don't work and some the MS JVM works for databases and not the Sun JVM. Although it used to work before they patched windows.
There are quite a few people having this kind of problem on the forums! I hope Sun is listening.
If the MS JVM is missing, is the Sun plug-in still installed (test by typing 'java -version' in a command window)?
If so then you might need to install a different version of the Sun JVM to get it working again.
Some questions for you to find out what the problem is.
1. Which version of XP is it (Home or Pro)?
2. Is the MS JVM and the Sun JVM removed (chech 'Add/Remove Programs' and try typing the commands above into a command window (Start -> Run -> "cmd").
3. If the Sun JVM is still installed, do applets using the OBJECT tag still work?
Let me know and I'll try and help.
Alastair.

Steps involved in writing java application on win CE

I want to develop a java application in win CE platform for a handheld device.
1. What are all the steps involved.
2. Is there any simulator available for win CE so that I can run my java application.
Advance thanks,
Regards,
Balasubramaniam.K.R

The way I developed my first app for the Compaq iPAQ
1. Install PersonalJava
2. Build app using AWT classes only (although I think SWING can be used)
3. Screen size 240 x 295 (thats what I used)
4. Compile and run on PC
5. Move to PPC (fingers crossed)
6. You may want to add an app.LNK file (kinda like a *.bat file) to setup classpath and file args
Sun has a compatibility suite you can run against your app to make sure it is PJava compliant. http://java.sun.com/products/personaljava/javacheck.html
Also make sure you don't use classes/methods that aren't supported
There is a PJava emulkation environment, but I never used it.

Java blocks webos doctor

I have an HP touchpad wi-fi only. I was trying to install the webos doctor as my device has been increasingly cranky and not opening some referred websites and mime files. I got the doctor partly installed and Java blocked the completion saying the certificate was out of date. When I checked the box to take the risk, Java still blocked the installation saying it was dangerous to install the program.
How do I "refresh" my tablet? As I am sure you know, HP no longer supports the tablet :-( Many thanks.
This question was solved.

Hello, and Welcome to the HP Support Community!
Here's my standard "How to Doctor a TouchPad" reply. See if it helps at all.
How to Doctor an HP TouchPad (reflash the ROM)
On your Touchpad be sure to have:
USB cable. The battery is charged to at least 30%.
Computer:
Windows 7, Windows XP, Windows Vista Available USB port (not a hub or secondary port). Java 1.5 or later is installed. If you are not sure about what version of Java you have, or even if Java is installed, go to www.java.com and click the Do I have Java? link to install the latest version of Java. 210MB of storage space. Internet connection.
Miscellaneous Info:
The update process will take approximately 15 minutes. During this process, your device will not be available for use.
Downloading webOS Doctor
Download webOS Doctor on your desktop computer. If you have a webOS profile, get it from http://ws.hpwebos.com/webosdoctor/sorry.htm
If not, check the webOS Internals page: http://www.webos-internals.org/wiki/Webos_Doctor_Versions
Get your TouchPad ready to update
Hold the Power Button for several seconds until a menu appears. Tap Shut Down to completely power down your device.
Running webOS Doctor
Double-click the file that was downloaded to run webOS Doctor. Follow the on screen directions up until you are asked to connect your device. Select the language you selected on your device, and click Next. Confirm your language choice. Click Accept to accept the terms of use. Click Next. webOS Doctor checks your system. BE PATIENT! I've seen this part take a few minutes to complete. After webOS Doctor finishes checking your system, you will be asked to connect your device.
Connecting your device and finishing the webOS Doctor update
Connect your device to your computer using the USB cable. You must connect your device directly to your computer, not through a USB hub or other intermediate device. Now the tricky part. Hold the Volume Up button on the device and insert the USB cable. After the large USB symbol appears on screen, let go of the Volume Up button. If you see the HP logo instead of the large USB symbol, you may have let go of the Volume Up button prematurely. If this occurred , wait until your device boots up, shut down your device and then repeat step 2. Windows will find your device and may offer to install two different drivers. When asked to install drivers of OMAP, select No, not at this time. When asked to install drivers for Palm Novacom (bootie), select Yes and let the drivers install. This may take a while. Once the drivers have been installed, the Next button will become available in webOS Doctor. Click Next. Do not disconnect your device from the computer during the update process. When the Reset Complete screen appears, click Done. Wait a few minutes for your device to reset. You're done!

Why is java blocked

Is java blocked by OS on iphone 5?

No iPhone has ever supported Java. Search the app store for an app that will permit you to view sites that use java applications.

Java blocking related problem

This question is related to other questions in this discussion thread, but about a different aspect.
The program on my QNAP NAS uses Java to bring up the dialog for the selection of files to upload. Each time Java is updated this code has the problem that it doesn't find Java activated. Some other programs seem to do this themselves, but alas the QNAP code does not. A workaround is usually not to use Safari but Firefox. However, today even that didn't do the trick. Only after accessing a site whose code does activate Java itself, is the QNAP code satisfied. As I have no control over QNAP's code (and content with the current version of its system) I would like to know if there is another way to do the Java activation. Once done, I guess it will stay that way until the next Java update. Perhaps something in Terminal? I am not afraid to use that.
By the way: I have the Safari Preferences Security tab checked on "Enable JavaScript" (change and change back doesn't solve the problem, not even after quit and reopen). In the Internet plug-ins tab checkbox "Allow Java" under the button "Manage Website Settings ..." the website of the NAS is listed as having full allowances. More settings relevant to the problem I cannot find. Using the latest MacOSX.
A side note: In "Manage Website Settings ... there are four possibilities, under which "Allow Always". The strange thing here is that in contrast always an alert comes up, asking if I want to block or not. But that is the behaviour I should expect instead from selecting "Ask before Using". Is there an explanation for this? Allthough it is not so much a hindrance, I find it strange behaviour given the label.
Thanks in advance for your contributions on the solution of this problem.

You could try installing the Phony extension and set it to Desktop Firefox. If that allows you to connect to the server then your company's server is doing a bad job of detecting Firefox browsers.

If that does not work then I don't know of anything else we can do to assist as this is a privately controlled server.

Java Blocked This Morning

I seem to be having Java plug-in problems with both Mac OS 10.6 and Mac OS 10.7 systems on our network this morning, in both cases Java applications are unable to run either from Safari or Firefox. In 10.7 I get a message about the plugin being blocked and am directed to the Java website to download an update, however, the version presented is the same one that is installed that is getting blocked (I downloaded and installed it anyway but the blocked message still remains). In 10.6 I get a message about an invactive plugin and when I click on the arrow to activate it it launches Apple Software Update which indicated that everything is up to date. Today is the last day in our pay period and our Timesheet application runs in Java so I really need to get this resolved quickly.
Does anyone have any pointers on reenabling Java?
Thanks in advance.

Apple slammed the door again on Oracle's Java this morning, due to its presence as a vector for malware intrusion. It will remain closed until Oracle decides to fix it, and Apple determines that it is no longer a threat.
You can override this protection at your own risk.
Warnings
By performing the following you understand and acknowledge that you are intentionally modifying OS X's built-in protection against the open security threat presented by Oracle's Java. In other words you're on your own.
By modifying OS X you may break your system.
Do not proceed without a backup plan.
I do not use Java because it is a security threat.
You will need Apple's Xcode. Download and install it here: https://developer.apple.com/xcode/
An application such as EasyFind will help find the file you need to modify. Download it here: http://www.devontechnologies.com/products/freeware.html
Using EasyFind or similar utility, search for the file Xprotect.meta.plist. Make EasyFind look like this:
Double-click the highlighed file to open it in Xcode. Click the "reveal triangles" under PlugInBlacklist until you find the highlighted entry for Java's minimum plugin version that looks like this:
Notice the entry String 1.7.11.22. If your version is something different than that it would be best to not proceed since it would be different than what my .plist is showing.
Click the String so that you can modify it, and change the String to 1.7.10 or earlier version of Java 7.
File > Save.
Quit Xcode.
Quit EasyFind.
You may need to reboot your Mac for this change to take effect.
This should enable you to use your Java-based timesheet application for today.
Subsequent updates from Apple will modify Xprotect so this will only be a temporary workaround, if it works at all. I cannot confirm that it will - see Warning #4 above.

Java blocking dequeue

I am writing an application that is to read messages from a queue.
The application is implemented in java using the oracle.AQ packages.
In my application I have a number of background threads that reads from a queue.
A thread will issue a call to dequeue a message. If there is anything to dequeue it will dequeue it without problems.
Now if there isnt anything to dequeue i have set the thread to wait for 120 seconds hoping that any clients enqueing within this timeframe will have their messages dequeued by the waiting thread.
My challenge is that the dequeue method semes to be blocking. My reader thread are waiting - but no clients are allowed to enqueue while reader threads are waiting.
Ive tried different options to make the dequeue non-blocking. Can anyone help me?
Some code:
queue = queueManager.getQueue();
AQDequeueOption dequeueOption = new AQDequeuOption();
dequeueOption.setWaitTime(120000);
AQMessage message = queue.dequeue(dequeueOption);
Ive tried to:
dequeueOption.setDequeueMode(AQDequeueOption.DEQUEUE_REMOVE);
but that didnt help..
Hope you can help!
Regards,
John P Jensen

I think you need to commit after every dequeue.
thanks

Is Java blocked again?

I was forced this morning to update to Java 7 update 17 from Oracle. Has update 13 before.
Then it was working for a couple of hours but now its blocked again. I'm trying to run the installation again for Java 7 update 17 but i just get the message that a higher version is already installed.
I have tried it on 3 different Macs and all have the same problem.
This is really getting on my nerves as it completely stops me from doing my work.

The download from Apple is the Xprotect framework which blocks Java from working. If you didn't download the updated Xprotect, then you could continue using your current Java version, which is insecure (and the reason Apple blocked it).
You can elect to have Apple update Xprotect and secure your system (by blocking insecure Java versions on your machine), or you can elect to have Apple NOT do this and run what Java version you want. But once Xprotect is updated on your machine, you MUST update Java or you must hack a plist file to run an insecure Java.
It's your choice. And just because you don't understand my answer, does not mean it's unhelpful.

Call a local program in Java class on Win

Hi
I'm now working on a Java project. It is needed to call a local program in Java class.
Following is the local program's source code:
#include <stdio.h>
main()
    char s[100];
    printf("Please input\n");
    scanf("%s", s);
    printf("Output: %s\n", s);
} I build this simlpe C program to a exe file named TEST.EXE
Then, I called the exe in my java class which was like following:
final Process p = Runtime.getRuntime().exec("test.exe > a.txt");
writer = new PrintWriter(p.getOutputStream());
writer.println("12345\n");
writer.close();
p.waitFor();But after I ran the Java, it seemed not what I hope to get in a.txt. the string "12345" had not been read by the program, and not been writen to a.txt.
Following is what appeard in a.txt:
Please input!
Output: Is there any error in my Java code?
thanks!

All above is my testing.
In fact, my project is to encrypt/decrypt by Gnu PG.
I need to execute a gpg command like following
gpg -r Luna --encrypt test.txt
I could execute this command line in CMD normaly:
C:\WP_ECL~1.4\TESTCE~1>gpg -r 8104EFB8 --encrypt test.txt
gpg: 997D0744: There is no assurance this key belongs to the named user
pub 4096g/997D0744 2002-07-31 Baker &Taylor Inc. <[email protected]>
Primary key fingerprint: BBBC F196 C1D5 CF26 170F D1FB 870A 3F60 8104 EFB8
      Subkey fingerprint: C161 4C33 F15C 5347 FD09 C2BE 8CC6 2302 997D 0744
It is NOT certain that the key belongs to the person named
in the user ID. If you *really* know what you are doing,
you may answer the next question with yes.
Use this key anyway? (y/N) y
C:\WP_ECL~1.4\TESTCE~1>Please pay attention to the line which I have to type a 'y' to confirm.
This make me have to invoke this command in Java class like following(in my understanding):
final Process p = Runtime.getRuntime().exec("cmd /C gpg -r Luna --encrypt test.txt");
writer = new PrintWriter(p.getOutputStream());
writer.println("y");
writer.close();
p.waitFor();But while the java code was being run, it would be blocked, waiting, waiting and waiting.
But this method was succeed in my test which invoked test.exe above.
I cannot understand what difference exists between my test.exe and gpg.
thanks.

Cannot run java application in Win XP

I worte a java application(a Swing app), I test it and run under win NT, it works fine for me.
Then I recompile it in my WinXP using j2sdk1.4.1_02, run it in a command prompt, but it does NOT start up the application, I check the window task manager, a java.exe already startup and it eat up 100% CPU of my XP, but the application never been startup.
My Swing application is not a JApplet but a JFrame.
Does anyone have the similiar problem?
Thx in advance
Henry

Try adjusting your path settings to stop using the MS VM (did you recently use win update?):
My Computer->Properties -> Advanced -> Environment Variables
System Variables -> "Path"
If it currently starts with:
%SystemRoot%\system32;...
change it to:
.;%JAVA_HOME%\bin;%SystemRoot%\system32;...
If you haven't set JAVA_HOME, create a new variable like:
JAVA_HOME = C:\j2sdk1.4.1_02
Note that using the ".;" before path makes the current dir's executables take prevalence over a same-named executable in a subsequent path.
Putting "%JAVA_HOME%\bin" before "%SystemRoot%\system32" makes certain that the current java.exe gets used (not Micro$oft's java.exe)
Try it, hope it helps,
Georg.

Fonts in java apps for win and linux

Hi everyone.
i need to build an application mult-plataform, to run in windows and linux...
but i don�t know waht font i must use...the default font that java takes doesn�t exist in linux (dialog)...
waht font should i use in my app??
thanx

For going multi-platform it is easiest to stick to the logical fonts: Fonts named "Serif", "SansSerif", "Monospaced", "Dialog", and "DialogInput".
These fonts are guaranteed to exist on any platform, although their implementations may be different. If you use others then you'll have to figure out how to deal with cross platform issues.

SDDM 4 EA3: Unable to launch the Java Virtual Machine (Win 7 64bit)

SQL Developer v4 EA3 is working fine, but I decided to download the stand-alone SQL Developer Data Modeler because I had seen people recommending using it in favor of the one bundled with SQLDEV.
Windows 7 64-bit
Java (64 bit) installed into C:\Program Files\Java\jdk1.7.0_25
When I double-click the short-cut to start SDDM I get the following pop-up dialog error:
Title: Oracle SQL Developer Data Modeler
Unable to launch the Java Virtual Machine
Located at path:
C:\Program Files\Java\jdk1.7.0_25\bin\msvcr100.dll
***NewsFlash***
I think I stumbled on the solution just prior to posting, so here is what worked for me in case anyone else runs into this....
I had created a desktop short-cut to "C:\Program Files\datamodeler\datamodeler.exe", which I am guessing is the 32bit version of the binary file.
I was able to launch successfully by pointing to "C:\Program Files\datamodeler\datamodeler64.exe"

That path is incorrect - strip everything after the jdk1.7.0_45\

Simple java compiler for win

I used the javac command in dos mode to compile my .java files , but in my recent program i have so many errors that they dont fit into the dos screen(in dos mode i cannot move up and down!).
Is there any simple compiler for windows(or GUI) that could solve my problem?

If you haven't done this already you can right click on your Dos Prompt icon and go to properties, then go to Screen, then change the initial size of your prompt to the largest it will go, (50 lines I think). That might give you a little more room...
