Regarding a browser running in a Java applet

Hi,
I'm pretty new to Java so please, bare with me.
Would it be possible to run a fully functional Firefox (or other browser) instance in a Java applet, provided the server is a Fedora box with virtual frame buffer?
If yes, what would happen if I download a file, where would the file be downloaded? The user (me) or the server the applet is hosted on?
Thanks in advance for your thoughts!

Thanks Chuck!
I'm just trying to create for myself a tool which is able to act like a browser. I'm using currently a headless user on an X, then exporting the X window to an image.
I was thinking to effectively bound the virtual frame buffer to an applet. Say, the vfb is running on display :11 and to bring that display to the applet, in live. Applet because I can't think of any other thing which would be able to do it.
So you think this would not be possible?

64-bit firefox on ubuntu 11.04 crashes trying to run 32-bit java applet, should this be possible?

on 64-bit Ubuntu installation I need to be able to run a 32-bit java applet within browser. If this is possible, how? With icedtea6 plugin (for 64-bit jre) firefox crashes when applet first starts to run.
11.0+build1-0ubuntu0.11.04.1

Hi,
You can try to install the Oracle Java via the Ubuntu Software Manager/Update Manager/PackageKit/Package Manager, if it is an option. Please note that you may have to temporarily disable the IcedTea plugin in '''Tools '''('''Alt '''+ '''T''') > '''Add-ons''' > '''Plugins '''to prevent conflicts when playing Java content in Firefox. Posting in the [http://ubuntuforums.org/ Ubuntu forums] would also be very helpful.

Running an ActiveX component wrapped as a Java Applet. How to do it?

I have a legacy ActiveX/ocx plugin that the client wants to be run as a Java Applet. They think that will make things J2EE compliant.
How would you wrap that? are there libraries to help?
Thanks in advance

thanks for trying to help since I wasn't able to find the appropriate category given the new change (discussions.apple.com/thread/6421739)

Can't load java applet? help please?

I am trying to load a java applet after an upgrade - but security settings are blocking it - please help

Java is no longer supported on Mac OS X 10.6. The security of Java has been found to be so bad, you are lucky to get any Apps that work wtih it. You need a minimum of Mac OS X 10.7.3 to run the latest Java applets and that using Java from http://www.java.com/ See the user tip here to optimize Java under 10.6.8

Create a file at a Windows Vista using java applets

I have created a java applet which is downloaded to create local file at a Windows Vista PC. The java codes are:
File out = new File("c:/users/test/hkuesd.properties");
FileWriter fw = new FileWriter(out);
PrintWriter pw = new PrintWriter(fw, true);
pw.println("#sample property file");
pw.println("key_path=C:/");
pw.close();
fw.close();
If I turn off "Users Account Control" under "Control Panel" --> "User Accounts", the file "hkuesd.properties" is created at c:\users\test and can be found using windows explorer.
However, if I turn on "Users Account Control", I can not find the file "hkuesd.properties" using windows explorer. But the file can be detected if I run another java applet program with the following codes:
File xpdir = new File("c:/users/test/hkuesd.properties");
FileInputStream fis = null;
if (xpdir.exists()) {
try {
fis = new FileInputStream("c:/users/test/hkuesd.properties");
Properties p = new Properties();
p.load(fis);
fis.close();
privateKeyPath = p.getProperty("key_path", "no value");
catch (Exception e) {}
Interestingly, if "Users Account Control" is on and I created the file "c:\users\test\hkuesd.properties" manually, the file creation codes
mentioned above seems to create another "hkuesd.properties" at the same "c:\users\test". The evidence is I run the second java applet program which can detect the one created by the first java applet but not the one I created manually.

I agreed that it is hardly explained in words. I
suggested to write two
simple java applets using the codes and you will see
the effects:
(1) the first applet can create a file
"hkuesd.properties"
(2) cannot find the file using windows explorer to
search the whole drive.
(3) However, can read the content of the file using
second applet.You still haven't address your problem of swallowing exceptions. Your code might be throwing an exception that tells you exactly what the problem is. Change your code to display or log that exception.

Running a Java Applet on Mac OS browser

I'm having trouble getting my Java Applet to work properly on the Mac OS version of IE5. Basicaly, the app fails to appear. Are there any do's and don'ts regarding the running of Java Applets on Mac Browsers?
I read somewhere that you can't send parameters through to the Applet. Is that true? I'm not trying to do this and it's still doesn't work.
Any help would be appreciated.

If anyone can help me with this problem I would be greatful.

When using Java Wizard with Firefox 3.6.23 on a Mac OS X 10.6.8 it keep getting an error message: "The Java Wizard cannot run. Please configure your browser to allow Java applets to access the filesystem." Have NO idea how to fix this problem.

When trying to upload files I received the following error: "The Java Wizard cannot run. Please configure your browser to allow Java applets to access the filesystem."

If the problem is with a site that is hosted using MOVEit DMZ by Ipswitch, please notify the site owner of the issue and ask them to apply the patch that is available on the support site to resolve the issue.
This is a better resolution than downgrading your version of Java that was updated due to security issues.

After downloadeding the latest Java plugin, I start to receive "Please configure your browser to allow Java applets to access the filesystem" message when I try to run a download wizard. What do I need to do? BTW, IE does not have this problem.

I had no problem using a download wizard Java applet to download file to my computer from an SFTP site using Firefox. When I tried to do the same thing with Chrome, I was told to download the latest plugin. Once I did that, I receive the following message when I run the downlaod wizard:
The Java Wizard cannot run.
Please configure your browser to allow Java applets to access the filesystem.
I got the same message using Firefox and Chrome. However, I have no problem using IE to run the same download wizzard. Please help.

If the problem is with a site that is hosted using MOVEit DMZ by Ipswitch, please notify the site owner of the issue and ask them to apply the patch that is available on the support site to resolve the issue.

Java Applets not running in Any browser

Hi,
I have JRE / JSE (1.6.17) installed on a windows 7, 32 bit Intel Machine.
I am able to do all the programming and stuff (in Java), but when i try to open a web page with a Java Applet, it just does not show.
The page gives a message saying that an additional plugin is required.
I tried, Google Chrome, Firefox, Internet Explorer...all have the same problem.
The environment variables are correctly set.
This is something completely new for me, so would appreciate some help

Actually i think its more related to JRE.
I was actually referring to general applet loading.
I cannot open any applet in any browser.

Problem running Java applets since Java update 2 (1.6.0_20)

Hi,
Since I upgraded to Java update 2, Java applets started having problems. The most noticeable ones are:
Non-modal windows appear behing the browser Window (tested Safari 4, 5, Chrome 5).
Double buffering not working as usual (slower, white boxes appear when dragging a window, etc.)
Slower rendering in general
The same applications run perfectly using Java Web Start. And they used to work very well also in Java update 1.
The application can be tested here (press ok if a login prompt appears):
Java applet: http://jmap3.k2geospatial.com/montreal_applet/
Java Web Start: http://jmap3.k2geospatial.com/montreal_jws/dockingClient.jnlp
Our applications running in applets use the new plug-in 2 with JNLP files.
Notice the Java startup splash (the animated sun-like logo) is not moving as smoothly as usual. It is very jerky now.
Are these problems known by anyone?
How can I downgrade Java to previous version?
sorry I cross-posted this in Unix forum also. I think it is better here.
Thank you,

Since the last Java update on mac, all my OpenGL applets stop working and now just shows a white screen on Chrome, Firefox and Opera. They was working well on all browsers (Safari/WebKit,Chrome,Firefox,Opera) just before the update.
The trouble maker seem to be the java plugin 2 and the new offscreen rendering pipeline, as reported by jrhaddad with the disucssion linked to the different Java/OpenGL community forums.
This is a huge regression for me, and I think for all hobbies/ independent developers and all companies who are doing some Java/OpenGL develoment. All our work just stop working since this update.
If would really want to know from Apple if they are working on this problem and/or how this can be solved.
Should this be fixed by Apple with a new java update, or should the various browsers must upgrade their applet support plugins according to the new java plugin 2 changes ?
Best Regards,
Jérôme

Using external libraries over signed Java applet: InvocationTargetException when running locally with 7u51

We have a signed Java applet that uses external libraries, specifically the OpenOffice application libraries.
We have a problem running Java applet with 7u51 of "InvocationTargetException" when use these libraries OpenOffice, that is not signed; regardless of the browser used (Mozilla Firefox, Explorer, Chrome).
Please, as you could solve this problem? This problem can not arose with 7u40 and earlier..
Best regards.

I am trying to use an education program that needs Java applets to install and use and it will not use Safari. When I download IE from the web it will not install. How can I get a browser that will work on my MacAir for travel use of this program?

I am trying to use and education program that needs Java applets and it will not run on Safari. IE will not install from the web. How do I get a browser that will work to install so I can use this program when I travel.

Try using FireFox. IE will only run on a Mac if you run Windows on the Mac.
Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
Install the Apple Boot Camp software. Purchase Windows 7 or Windows 8. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7. Parallels is software virtualization that enables running Windows concurrently with OS X.
VM Fusion and Windows XP, Vista Business, Vista Ultimate, or Windows 7. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not as fully developed for the Mac as Parallels and VM Fusion.
Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. A more recent comparison of Parallels, VM Fusion, and Virtual Box is found at Virtualization Benchmarks- Parallels 10 vs. Fusion 7 vs. VirtualBox. Boot Camp is only available with Leopard and later. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.
