Run application from applet

is it possible to run an application from an applet? is so how can i go about doing this?

hey may be the use of Runtime can help u solve ur
prblm....
Runtime.exec("Application name");luck,
jayNope. You should know some basic things before trying to give answers.
If (unsigned/untrusted) applets could just run any other app, imagine the chaos when someone hits a rogue website containing an applet that executes something like "format c:"
You want to run an external program on the client's machine from an applet? You can't, thank heavens. You need to rethink your design.

Start application from applet

Hi there!
I have to start an application from applet (is not my idea, i HAVE to do it). That menas (i think) i have a little problem with the java "sand box". How can i make my program run out of it? Signed Applets? Are there also other possibiliys? Can i make as "privat person" signed Applets?
Thank's

This is SAX-parser for XML processing. The XML-files are local saved, also the applet and the application. The Parser application seems to start, but (sic!) there is no output, even though the application is OK...

Crashes when running applications from network share - "Windows cannot access the file for one of the following reasons"

Hi,
starting a couple of weeks ago, we get the following error(s) when running applications from a network share. We don't know what causes this, we are not aware of any major changes in our network infrastructure or client/Server configuration. We did upgrade
a lot of machines to Windows 8, but the issue also occurs on older Win7 computers.
We figured out a workaround though: The applications run fine when launching from a FQDN share (like
\\share.domain.Company.com) and only cause problems when running from
\\share directly. They have worked fine for years without FQDN though.
Any ideas?
Error Details (the Kind of error differs greatly):
# 1 #
Log Name: Application
Source: Application Error
Date: ...
Event ID: 1005
Task Category: (100)
Level: Error
Keywords: Classic
User: N/A
Computer: vmDEV
Description:
Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program XYZ
because of this error.
Program: XYZ
File:
The error value is listed in the Additional Data section.
User Action
1. Open the file again. This situation might be a temporary problem that corrects itself when the program runs again.
2. If the file still cannot be accessed and
- It is on the network, your network administrator should verify that there is not a problem with the network and that the server can be contacted.
- It is on a removable disk, for example, a floppy disk or CD-ROM, verify that the disk is fully inserted into the computer.
3. Check and repair the file system by running CHKDSK. To run CHKDSK, click Start, click Run, type CMD, and then click OK. At the command prompt, type CHKDSK /F, and then press ENTER.
4. If the problem persists, restore the file from a backup copy.
5. Determine whether other files on the same disk can be opened. If not, the disk might be damaged. If it is a hard disk, contact your administrator or computer hardware vendor for further assistance.

Hi,
>>The applications run fine when launching from a FQDN share
It sounds like a DNS suffix issue. When this issue occurs, please try to ping share on the client, then check if the corresponding IP address is correct. If the IP address is wrong, please adjust your settings of DNS to make sure that the client can resolve
the share correctly.
If it's very hard to change the settings of the DNS for some reason, as a work around, we can add the entry into the clients' hosts file.
Best Regards.

Close a running application from java........

Hi all
I have opened an application say MSWORD from my java class using Runtime.getRuntime(), Now on close button i need to close the application and on the save button of the application i even want to save the application from java command
The question is HOW????
please reply,
Thanx,
Amitt

can I open the konsole from java??Yes.
First you must figure out how to do that from the command line yourself. That has nothing to do with java.
Note that that how you do that MUST account for the fact that the "command line" is actually a shell. Some commands must be run by running the shell as the actual command and then passing the desired command as an option to the shell (the actual command.)
Again you can google for examples.

Running application from installer in vista prevents drag and drop

Running a desktop application from Vista and Windows 7 through a wizzard, prevents doing a drag and drop from the desktop or another windows explorer to our java application.
We are using a windows wizard to install the application once it finishes it launches the application within the application the drag and drop work perfectly, but I can not drag from desktop or external windows explorer into my application, dragging from the application to the desktop or to another windows explorer is working fine.
If we run the application by clicking directly on the exe file (generated by the installer app), the application launches and do not present the anomaly (Drag and drop into a out side the applications work fine).
So the issue might be related to the way the installer executes the application, that maybe have a different configuration or windows permissions are not set correctly when started by the installer.
Both ways of launching the application have the same working directory the only difference i found was in the system environment (System.getenv()) the one that works has a SESSIONNAME key with a CONSOLE value in it, could this be the problem?
Any idea on how to workaround this issue or some idea to look at the installer will be kindly appreciated.

One idea is to use [Java Webstart|http://java.sun.com/javase/technologies/desktop/javawebstart/index.jsp] *(<- link)* as your installer. It might not fix the D'n'D problem, but at least if you get to the point of telling Sun about it, they will care (at least) one iota about fixing it.

Wtih Parental Controls on, need to allow run application from CD

Hello
I have restricted my sons access/login using the parental controls and everything is working well except that some of his apps run from CD i.e. Wiggles stuff
Anyway, with parental controls on his login does not allow these to run, we get a permission denied error. Is there any preference/control in Tiger or Leopard that will allow his apps to run?
Thanks
Rick

Boot Camp is most likely to work, but requires that you restart the computer to change OSes; nearly all Windows applications will work through this method.
Parallels Desktop and VMware Fusion run Windows from inside Mac OS X through emulation. Applications which require direct hardware access likely won't work, and this method is slower than Boot Camp. It is more convenient to use, as no restarts are needed.
CrossOver Mac and CrossOver Games translate the Windows instructions directly to Mac OS X ones. This is the cheapest method if you don 't already have Windows and the least compatible one.
Stating which applications you want to use will enable more specific advice to be provided.

Can not Run Application from Client PC.

Hi,
I have a pc running on WinXP called "PC1". I have installed Oracle9i Database, Developer Suite 10g and services. I can run my application smoothly on "PC1".
My problem is that i can not run my application from client pc running on WinXP called "PC2". I have installed JINIT.exe on "PC2". I started OC4J also on "PC2". IE shows "Page can not be displayed" message.
What settings i have to do to run my application on Client i.e. "PC2".
Waiting for any kind of help.
Thanks.

Hi all,
Thanks for the reply.
I have already install same JINI.exe on Client "PC2" which is on Server "PC1". And the version of the IE and JINI are same on Server "PC1" and Client "PC2".
I start OC4J on Server.
Should i make some settings on JINI Control Panel on Client ? Like Proxies.
I have enable all check box on "Basic" Tab of JINI.
Further, On client, the check Box of "Show Java Console" is also on, but when i try to connect my application from IE, the Java console does not appear.
I would like to inform u that, when i start additional Proxy driver like Analog proxy on my server and then i give that proxy address and port in Client IE connection LAN setting, i am able to run my application from that Client.
But i think that is not the solution.
Waiting for reply.

Run vbscript from applet.

Hi,
i have a vbscript to perform doc to pdf convertion. I placed vbs file in jar and tried to execute with getRuntime().exec

Thanks in advance..

Runtime.getRuntime().exec("wscript \"\\doctopdf.vbs\"");1) Use ProcessBuilder for a 1.5+ app.
2) A file argument with no spaces usually can be included without quote marks.

..Is it possible? Or any other way to perform my task?You might expand the script out to the local file system (e.g. to the temp directory) and run it from there. Of course, that would fail on this box, as mentioned earlier.

Running applications from terminal [SOLVED]

I am brand-new to Arch and aside from Ubuntu, have no linux experience. I have arch up and running with openbox as my WM, but I am at a loss of how to run applications. I type firefox, or Thunar into the terminal and receive errors that read:
firefox: symbol lookup error: /usr/lib/libgtk-x11-2.0.so.0: undefined symbol: 9_datalist_get_data
or with obmenu:

Can I run applications from an external hard drive

Hi I am a sort a new Mac user and I would like to run Lightroom from an external drive. Is this possible on a Mac?
Thanks!

Yes, but it will load a little slower. If it does disk I/O from the external then that will also be slower.

Run application or applet on any windows machine

OK, here is my question. If I write a application using swing, and then build the application into jars, can I take that app and run it on any computer, or does any computer I run it on need the jdk installed on it. The reason I am asking this, is a am writing some simple software using swing as a GUI. I want other user's to be able just to copy this app from a disk, set it on their computer and run it. Will this work, are will it work if I use applets. Please let me know.

what do you mean by make a webservice app or use webstart/jnlp

Run application from applet
