Applet that launches application... possible?

i want to launch a java application (in the form of a jar file) that is already on my hard drive using an applet. i want the application to run in its own DOS window locally. is this possible, if so, how? (i will sign the applet, so that should not be an issue)
thanks for the help...

Just construct a JFrame, add stuff to it, and call show().

Launch application like "word"

Hello all,
I have build an intranet with resin2.0.16 and JDK1.3.
And in this intranet i want to launch application on client PC.
I can run any application for the moment but only in the web server.
Is it possible to run application on the client pc ?
Thanks for reply

I suppose you could create an applet that launches a program on the client. You would have to sign it to get around the security restrictions.

Trying to write an applet that reads/displays a file from a remote server

Hey all,
I'm trying to make a little applet that launches from a browser that allows me to read a file from a server, reads it line by line and displays each line, and continues to read/monitor the file until I get a specific line of text.
I've tried to do some code and although I can read the file (and display it), I can't seem to detect the end string (the if statement that tests if the line == "--END--" seems to have no effect, i.e. constant false).
I have a feeling the approach I took is wrong since this seems insecure and just looks bad (I've seen stuff that seems to indicate I need to do something with implements Runnable or something.) Even if anyone doesn't have the time to actually do the framework of this, if they could perhaps outline an approach and any necessary topics I need to look at (such as
1. Go and read the threads tutorial.
2. Go and read the X section in the Y tutorial.
3. Check out this <link>, as they seem to be doing something similar to what you're doing.
Thanks in advance.

          if(end == true) {
               area.setText("finito");
          else area.setText(display);
}

use tmp.equals("--END--\n") instead of tmp == "--END--\n"
The == means does tmp reference the same object as "--END--\n" which will probably never be true. Using the equals method means does tmp contains the same characters as "--END--\n"

When I try to launch itunes I get an error mesage saying that Apple application support was not found and suggests that I uninstall and re-install it, but that doesn't work

For general advice see Troubleshooting issues with iTunes for Windows updates.
Start with the section Install missing components which should address your particular error. Otherwise the steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
If you've already tried a complete uninstall and reinstall try opening iTunes in safe mode (hold down CTRL+SHIFT) as you start iTunes, then going to Edit > Preferences > Store and turning off Show iTunes in the Cloud purchases. You may find iTunes will now start normally.

Can you use an application in hyper-v environment in Windows server from each client computer or that is not possible?

hi,
I like to know besides running 2 or more operating systems,like exchange or SQL ect .
what other benefits it has for example when you install 2-3 applications in t hyper_v environment can you use those applications from each client computer or that is not possible at all. ( I don't mean cloud )
thanks
johan
h.david

thanks,
so , now what is the benefit of hyper-v role on essential 2012r2 . it that means that I can install only one operating system on it only one instance and no more. also I can run some applications on this server just like you say with RDP licence
for each user to acces this virtual server!
and if I want more instances then I have to get datacenter.

Launching applications from an applet

How do you launch applications from an applet? For example,launch a notepad exceutable when you click on a button (an awt component)?

Hi,
you can launch an application from the applet using the Java RunTime environment.
Runtime.getRuntime().exec(applicationName);
But to do this the applet needs permissions.It should be a trusted applet.

When I try to launch iTunes is says that the application can not be opened

When I try to open iTunes it says that the application can not be opened, that the required folder can not be found. On my husbands log-on iTunes will open. I am so confused. Please help!!!

Hello Keaton44,
I recommend taking a look at this article named iTunes: Finding lost media and downloads found here http://support.apple.com/kb/ts1408
If you need to re download the movies you bought from iTunes you can do that free of charge with this article.

Is possible hide the front panel of a vi that launch other vi?

We have a vi that launchs other vi( modal subvi, that shows his front panel).
But while is running this subvi, I want to "hide" the vi, and when the subvi finish we want to show the vi's front panel.
How can we do it? I check property node /Invoke node functions, but I don't find any good solution!
Any idea?
Best regards,
Graci

Here is a vi that does exactly what you are asking for.
Sorry for the french comments... It should not be to difficult to understand the code.
You must call this vi twice in the subvi.
1) With the input set to "Masquer" (--> hide) at the beginning of the execution of the subvi.
2) With the input set to "Afficher" (--> show) at the end of the execution of the subvi.

Soap and Applets? Is it possible?

Is it possible to use SOAP in a java applet, without having a massive
JAR file that the user is required to download? With my current applet,
I keep on getting the following exception:
java.lang.NoClassDefFoundError: javax/xml/soap/SOAPException
What I'm trying to do is have an applet that gets downloaded to the
client that gets some page info via SOAP from a .Net web service with
a SQLserver database. Any ideas? Is this possible? It should be, as
it SHOULD be just XML over the wire. Or should I try something other
than SAAJ?
This is my current applet. Anyone see any bugs that would prevent
this from running as an applet?

SGD - Fails to launch applications

We are having a problem with SGD - we can not launch applications.
We have SGD 4.2 running on a Solaris 10 server.
We had SGD up and running good. However, we had several things occur and now it does not work. First we had to relocate our server due to building renovations. Then shortly after setting up the system in the new location, we had a hard drive fail. And unfortunately the sys admin guys did not have a good/current backup of the drive. We did however reload a backup that was about 9-months old. However it does not work correctly now.
We can bring up the main SGD web page, can login to the system, and see the applications and function set up in object manager. However when we try to launch an application it fails.
Looking in the error.log file we see a message "failed to open display"
However we can not see how SGD sets the display to enable the application to be viewed over the web connection.
Any help would be greatly appreciated.
Thanks,
Mike

It is a good thing to have as much help as possible. One of the other SAs working on the problem entered his google search a little different and came up with this hit: (http://blogs.sun.com/malhar/entry/sun_secure_global_desktop_tarantella -- text below) that fixed our problem. Thought I would post it here for the next person who runs into the same problem.
Sun Secure Global Desktop (Tarantella) "DISPLAY variable not set" error message?
If you've been facing a problem with the erstwhile Tarantella, now Sun Secure Global Desktop (SGD), where you get don't see X applications opening up when you click the link, you're in luck.
I have the solution.
If you are fast enough to click on the "Show Details" button before the application loading window opens and then closes, you will see in the logs that the application cannot open because it finds that the DISPLAY variable is not set.
Also, if you read the documentation, you will see that the admin guide explicitly asks you to NOT set the DISPLAY variable which gets set automatically. So where's the problem?
What you need to do is this:
1. Open the /etc/rc.d/init.d/Tarantella script in your favourite text editor
2. Look for TTASSHCLIENT (this is usually commented out)
You will notice that the line will look something like this
#TTASSHCLIENT="";export TTASSHCLIENT
3. Uncomment the line
4. Add /usr/bin/ssh -X inside the quotes on the line to make the line look like this
TTASSHCLIENT="/usr/bin/ssh -X";export TTASSHCLIENT
And restart!
That's it. You're problem is solved. I accept your thank yous in advance

Auto Launch Application and perform some action

Hello Friends,
I am working on Autoback, want to launch application and perform some action to take backup.
Can any one please update me what all the J2ME phone supports this kind of feature and basic needs to implement Autobackup, any sample code available please let me know
Thanks,

Something sketchy.
I had the same message appear. It resized my window to the smallest possible size (not minimize!) and when I resized it larger, it had opened a new tab with that message. It was on "c510a1.minersaver1.com" which sounds like a related site. It tried to download "avmast_2004-4_mst5.exe"and I was going to try and refind this site on my Linux box, but forgot to save the exact URL (oops!).
Running Firefox 4.0b11 on 64-bit Windows 7 Home Premium.

Is there a way to stop the launching applications to come to foreground?

Is there a way to stop the launching applications to come to foreground?
Back with os 10.3 Panther or 10.4 Tiger the apps opened in the background. That was one of the good differences with Windows. I guess that 10.5 Leopard adopted this annoying Windows behavior. Hope it's gonna change with 10.7 Lion.
(Of course I am looking for another solution than the AppleScript/Terminal launch that can be found on Google. I'd rather have a plist option to change if it exists!)

I have found this page http://www.realsoftware.com/listarchives/realbasic-nug/2009-03/msg01167.html where it is proposed to add :
<key>LSBackgroundOnly</key>
<string>True</string>
to MyApp.app/Contents/Info.plist
I tried this but the app launches totally hidden in the background. Plus you have to set this behavior for every app.
The open -g option works fine as expected.
Still looking for a system-wide option, but it doesn't seem to exist.
About the utility of such an option, I'll just remember you that some machine don't load apps very fast and, instead of waiting for an app to launch, the user will do something else until the app launches. You'll understand that waiting in front of a computer isn't acceptable and having a MBPro isn't possible for everyone.

Can't launch application - 10810

After restarting all applications will launch, but after several minutes - when I try to launch a new application, I get the message "Can't launch application XYZ - 10810"
If I restart, then, again, any application will launch.

See if this helps:
The following have been suggested as possible solutions:
1. If you're using 10.3, you need to get rid of the following:
/Library/Caches/com.apple.LaunchServices.6B.csstore
~/Library/Preferences/com.apple.LaunchServices.plist
(where '~' means your Home directory, i.e. '/Users/yourname')
2. If you have Virex or other virus software installed, try uninstalling it. Be sure to use uninstallers that come with the software because simply deleting the application does not fully uninstall most virus software.
After deleting the referenced files above you will want to do a restart. Then use Disk Utility in your Utilities folder to repair permissions.

Overwrite class file that launched app?

Here's a wacky one for you:
I have a single bootstrap class file residing on customers' machines that launches a remote application. This bootstrap class file cannot be updated or changed directly. The only hope for making any changes to it is to have the remote application it launches update it.
In more general terms, there is a Java class file X (with a main method) that launches remote Java application Y (in a jar file at a URL). Is it possible for application Y to overwrite the contents of class file X on disk?
I realize that deploying a file that could not be easily changed was STUPID, STUPID, STUPID, but that is the situation I am now facing.
Thanks for any help,
Steve C.

> Then as you indicate, the program was designed
incorrectly and you want to find a way to make it work
without re-designing it. So are you saying you want
to fix a bug that's in a piece of code, but without
changing the code? Doesn't make sense does it?Everything in the system is updatable except for that one file. That file was designed incorrectly and needs to be redesigned. So at this point I need to use the parts of the system that can be updated to update that one file that is difficult to update. Whatever mechanism that is used to change that file must run that file as it << currently is >>, and that is why I cannot use Runtime.exec().
Thanks for your input,
Steve C.
