Launching applications (use Java or is it possible in C)

I'm a very newbie programmer in university still...
In any case i'm only fimilar with C, C++ and Java. I'm trying to create a program that takes arguments from the command line, then launches the program identified in the command line.
I know I can launch programs from java applications with: Runtime.getRuntime().exec
but i'm not sure how a Java program would recieve arguments from the command line.
I was thinking C or C++ might be more feasible, however i don't know how to lauch applications from within either language. I hear it's pretty easy to do what i'm asking with Visual Basic (but as I said I don't know it).
Any help?
Thanx in advance.

but i'm not sure how a Java program would recieve
arguments from the command line.Strange as it might sound, through the arguments of the main method:
public static void main(String arguments[])

Deploying no java applications using Java Web Start

Hi,
I am new to java web start. Is it possible to distribute non java applications using java web start. I have an APP which can run on a desktop in standalone mode. The app has jusy HTML and Java script files. Is it possible to package this app and deploying using java web start? I am assuming If it is possible, I can make updates to the packaged app in the web servers and the updates will be downloaded next time the app is used provided configurations are correct?
thx

The app has jusy HTML and Java script files. Is it possible
to package this app and deploying using java web start? Not really. Resources for JWS need to be zipped,
while this HTML/JS app. will (I guess) not work from
inside the depths of a Jar (or Zip) archive.
Note that you can organise for those files to be
downloaded and expanded onto a known place
on the user's disk, by using an 'installer' element,
but..
...I am assuming If it is possible, I can make updates to the
packaged app in the web servers and the updates ..installers are only called once, and do not 'update'.

What XML Parser are you using to get an atributte4s value ?
The JSP Demo makes a string comparison, but I want to use the XML Parser. How can I do this ?
Response DTD Example:

Launching applications from java code

I have found a solution to launch applications from java.I thought this will be useful for programmers who want to open a
1. Browser
2. Player
3. Files etc.
There are 2 solutions :
I)To use a known application :
eg: to open windows media player
String[] cmd = new String[3];
cmd[0] = "cmd.exe";
cmd[1] = "/C";
cmd[2] = "START MPLAYER2.exe "+mediaURL+" /PLAY /CLOSE /FULLSCREEN";
//eg: mediaURL = "\"D:/project/songs/track1.mp3\""
// /PLAY /CLOSE /FULLSCREEN this option can be used only for windows media player
// for any other application use cmd[2] as START apl.exe //apl can be any windows application
Process p = Runtime.getRuntime().exec(cmd);
II) To use a default application:
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + url);
// url can be any url

To post code, use the code tags -- [code]Your Code[/code] will display asYour CodeOr use the code button above the editing area and paste your code between the {code}{code} tags it generates.
And make up your mind what file type you're having a problem with. Maybe .asx doesn't have a file association on your computer.
This works just fine for .m3u:import java.awt.Desktop;
import java.io.File;
import java.io.IOException;
public class Playlist {
   public static void main(String[] args) {
      try {
         Desktop.getDesktop().
               open(new File("E:/Music/Playlists/test.m3u"));
      } catch (IOException ex) {
         ex.printStackTrace();
}db

Executing Jar Application using Java Programs

Hello there,
How can I run a java application using java programs.
Desc:
public class someapp {
public static void main(String[] ext) {
// How can I execute a jar application from here through java code
}

You could use java.lang.Runtime.exec(). Another way could be loading the main class of the jar file and invoking its main method dynamically.

How to launch MS Word application using java

HI:
I'm developing a project using java, but we need to launch Microsoft Word into java based GUI(like Jpanel, or Frame, things like that), could anyone be so kind that give some hints on how to do it?
thanks!

I would be pleasantly shocked to find out this is possible. Well, let me retract that. You might, just very, very maybe, be able to use a combination of Windows API and Word's API (either DDE or OLE or ActiveX) to interact with Word. This will involve using a lot of native methods, javah and pre-compiled DLL's written in C or C++.
But I think you will be completely stuck trying to get the UI to switch to a JPanel. Microsoft would have to have a version of Word independent of the UI (in effect, have designed Word to have a pluggable user interface). They may have done this, but I have never heard of a project where someone successfully swapped out Word's user interface with a custom Swing one.

I checked for other versions of jre but not using java cache didn't cause any problems.
I checked for the release note of update 19 but I have no clue.
Is there any way to launch java application without using java cache?

..I had a problem changing the cache location. The button for this action is disabled. I can't figure out how to enable it.On my system, it is enabled when the 'cache files' box is checked, and disabled when it isn't.
1) Without changing the location I assumed that deleting the cached files could be a similar job, so I clicked "Delete Files..." and deleted with all checkboxes checked.I am not convinced that would entirely clear the cache, but have done no specific tests to check.
2) I unchecked "Keep temporary files on my computer".So it was checked when you were trying to change the cache location?
3) Applied all the changes.
4) I launched your demo.
Result - It was launched without any prompt.
I revisited the page with the URL and successfully launched the app. again.The application launched just fine, but no prompt.
If you follow those (links and) steps I outlined exactly, does the file service demo launch twice for you?I'm sorry I don't exactly understand your question. .. Your description is enough to convince me that answer is 'yes'.
..I tried twice and it launched twice, but not twice at the same time(it launched once at a time).Surprise, surprise. That is the first mention in this thread of 'same time'/'simultaneously'. Care to share the other defining factors that you forgot to mention, or is guessing part of the 'fun' of helping?
But still I'm having problems with launching my application.
I assume that it could be jnlp syntax problem. The "main=true" subelement is missing.It is a good idea to validate the launch files of JWS based launches that are failing for any reason. For that purpose, I offer JaNeLA.
Having said that, a missing main='true' will not be detected by JaNeLA, since it is not a compulsory attribute. ..But check them anyway.

How can i built a java application using java debug class on Log4J

Hi,
As java API support the MethodEntryEvent, using which I can get the automatic logging statements when the method is entered or exited as HelloExample.main(with argument type).
Where HelloExample is the class name.
Main is the method entered with its argument types.
In some cases I have the o/p as
-- VM Started --
====== main ======
main -- HelloExample
callerMethod -- HelloExample
====== main end ======
-- The application exited --
By using Log4J is there any possibility of getting these sort of o/p along with the loggers supported by Log4J. i mean to say can i built an java application which supports the MethodEntryEvent and MethodExitEvent from java API and also uses the Log4J debugging. I took an e.g. trace example, which (in J2SE 1.4.x or 5.x) will be found in $JAVA_HOME/demo/jpda/examples.jar and unpacking it by
jar -xvf $JAVA_HOME/demo/jpda/examples.jar i found the com/sun/tools/example/trace/Trace.java and passed the class constructed with logger taken from Log4J. In this case the logging message is displayed on the console. As per the requirement i need to transfer the whole o/p to an output file along with Log4J logger statements. in this case i should not give any command in the cosule except compiling and executing the programme. the programm also should able to run without the main() as i need to integrate Log4J with an application and the code must me application server independent. i need the output as i got using MethodEnteryEvent (shown as above) in case of java application built using Log4J.
Can any one help me in this regard. can any one give me some suggestion or any programme of this sort. All suggestions are welcomed.
Thanks & Regards,

hi,
can someone help me how to implement logging for method entry parameters and
method exit return value.
can someone help me how to use log4j and integrate it to the method entry
logging and method exit logging.
Here what i need is without writing the log statements for the method entry and
method exit i need to log it to the file
along with other log4j debug statements i provide in the file.I should be able
to configure whether to enable/disable the logging
for method entry and method exit. In method entry i should be able to log the
parameters the method take and in method exit
i should be able to log te return value to the log file, before the method is
returned to the callee.
i hope i am clear
Thanks in advance.

Very Urgent Unable to Launch Application using Web Start using JDK 1.4.2

Hi all
I am very serious issue i have ejb client swing application that uses
RMI to contact a session bean deployed in JBoss now i want the client app to be installed in the client machine using web start . Also i understand i require security permission to access network resources. so i have signed all the JAR files with same certificate created using self certificate avialiable in JDK by default also in the JNLP file in have included the following tag
<security>
<all-permissions/>
</security>
Now when I launch my application using Web start it gives an error that " Unsigned application is trying to access local resources"
I unable to understand what could be the problem . Please help me with the steps to be followed where in client should be able to RMI call to the server
Thanks in Advance
Naveen

You may have tried this already, but you might have to sign the jars via command line, outside any export process from your IDE.
$ jarsigner {filename}.jar {key from keystore}
I also had problems using webstart and RMI through an RCP

Unable to run my application using java web start

i have created one application and use java web start to download the application. all the files are succesfully downloaded but when i try to run the application an expected error occur. this only happen in my machine but not in other machine i'm currently using
-jsdk1.4.2
-windows 2000 professional 5.00.2195 service pack 3
-pentium III 870 Mhz
-x86-based PC
-RAM 256 Mhz
Anyone knows why, plz help me with this puzzle

Please post the information from the Web Start "Exception" and "Wrapped Exception" tabs when the error occurs (I assume the error was in fact unexpected ;-)
A blind stab in the dark would be that you don't have write permission to the cache directory on the second machine. Also worth checking that the proxy settings on the second machine are the same as the first (if they are on the same network).

<b>where to get the jar and sda files to build the application??
In Developer Studio.. Windows -> Preferences -> Java -> Classpath variables. Is this the only place where we need to give the jar file path??
Are there any other configurations to do(except setting container variable to MDM4J jar file) to connect my java application to MDM repository???</b>
Regards,
Chand.

Hi Govada,
(1)You need to add the MDM4j and other JAR files at:-
right click on project -> Java Build Path -> Libraries -> Add External JARs
(2)If the project is Web Dynpro project one
then right click on project -> Web Dynpro Reference -> Library Reference -> and add sap.com/com.sap.mdm.tech.mdm4j
Are you using JAVA API 1 or 2???
Thanking you
