File associations are platform specific. For example on windows they are setup through the registry. On linux I can use Konqueror and it has its way of setting these up or I could use something else. Probably the easiest way is to write your own file explorer that does this.

Open a file in a running java program via double click

I have already implemented opening my program with the corresponding file after a double click in windows explorer or from the cmd line but how do you open a file into the program if it is already running as MS Word will open a .doc file in the current word instance if you are running it.
Thx,
Jim

Implement some sort of interprocess communication in your program. If you launch an instance, it can check whether another is running and pass a message to it telling it to perform the wished action.

URGENT: How to run a Java program from a different directory?

Hi.
How do I run a Java program from a directory that the file is not located in? So lets say im in c:\Java. But the file is in c:\Java\abc\efg\.
What would be the command to run the Java file from c:\Java.
I can't remember it and I need it asap.
Cheers.

If the class you are trying to run is MyApp.class, try
c:\Java\>java -cp abc\efg MyAppThe actual classpath you specify will depend on whether or not MyApp.class is in a package (I've assumed it isn't) and whether or not any 3rd party jars are involbed (I've assumed not).
Edited by: pbrockway2 on Apr 1, 2008 6:42 PM
The command arguments read as "Run the MyApp class using as a classpath abc\efg relative to here (c:\Java)".

Run a Java Program

Hi,
I created a java program using eclipse.. How can I package it and run the program in windows or Unix?
Thanks

Right click the project in the Package Explorer. In the popup menu go Run as->Run Configuration. Click the new configuration button. In the Name box pick a name for your configuration. Make sure the right project is shown in the project field. If not click the browse button and select the right project. Make sure the right main class is listed in the main class field. If not click the browse button and select the correct class. Click apply. Click close. In the popup menu click Export. Double click the Java folder so it drops down. Double click Runnable JAR file. In the Launch Configuration drop down box make sure the right project and main class is shown in this form: Configuration name-main class name. Click the browse button to set the location you are saving the Jar file to. Click finish. Now find the JAR file and double click it to start the program.

Running a java program a set number of times

This is a general question. Is it possible to make a java program run only 5 times for the sake of arguement.
Basically I want to write a program that will give the user some flexibility when it will actually run another Java program, but I only want them to be able to say "not now' for a set number of times. When the last time comes the other program will launch. I was initially thinking of the Do Whilw loop, but this needs to work when the program is restarted.
Program starts, it has 5 times it will run before it does something else(doesn't really matter now I think). User takes option "Not Now" and the program ends, but warns the user this will run 4 more times before you will need to do something.
This process will repeat until the user takes the option "Ok install now" or the time limit expires and the install occurs anyway. Can someone point me in the right direction.

ok I see so it's like one those programs that you download for free on the internet and they give you a set amount times to use it before you have to pay for it. but in this case when the number of times you use it equals 5 (or when the user clicks ok) a different java app will open automatically.
My first thought would be to Write a Serialized object to disk using objectOutputStream that stores the number of times the application has been opened. and each time the program runs it checks for the serialized object and then you can do something like what I posted before. of course if were worried about security the user could always look for the object and erase it, if so then I guess we would have to come up with another plan of attack
Hope this helps

Running a java program from an icon

I want to run my program from an icon on my desktop. I have a .bat file that I've built a shortcut to and it works.MY GUI program does display and run when I click on the icon. The problem is that the DOS window also shows up behind my GUI.
Is there anyway to prevent the DOS window from showing? Or is there another way to run a Java program without resorting to a DOS command line or running it through FORTE or another IDD?

Chris's solution worked well, with one small problem. Once my GUI starts, it takes up the whole screen. Normally when I run it, it appears as a small window.
not a big problem, I can reduce it easily after it starts. But does anyone know a way to make it come up in the reduced size it norally comes up in when I run it from my IDE?

Exception while Running a Java Program for UME.

Hi Experts,
                       I am trying to run a java program to acess UME. Its a sample to create user but all of my samples are throwing this exception in NWDS (Console).Can anyone tell me why is it throwing this exception .
com.sap.security.api.UMRuntimeException: UME factory 'com.sap.security.api.IUserFactory' cannot be accessed because UME initialization has not started yet.
Please check
        UMFactory.isInitialized() before using UME functionality.

Thanks in advance

Hi,
Earlier i faced the same exception when i tried to call the UME form Standalone java application,To resolve this i used stateless session bean approach. i follow the Below Mentioned Steps,
1:-- create an J2EE -- EJB module project.
2:-- Create stateless session bean and define the require methods ,implement Local and remote interface methods in your bean class.
3:-- refer the UME apis in EJB Projects build path.
4:-- Call UME in Bean class methods.Build the EJB project and Archive.
5:--Now create an Enterprise application Project ,Include the EJB module project to your EA Project by right clicking on EA project.Build EA project and EAR file
6:--Deploy the EAR file on your server.
7:--Now from your standalone java application include these two projects in Project tab of your Application.
8:--Lookup the stateless session bean in your java class by its default JNDI name ,Obtain remote or local Home interface,And execute the BEAN Method which deals with UME.
You can also refer this tutorial in some parts of it UME apis(like IUser,UMFactory) are used in Servelets and EJB ,You can download this tutorial source from SDN for your reference.

How can I start my Java Application using double-click in Windows XP?

I hava developed an editor in java. The file made by this editor is saved as the .cte format. so, I need to associate this file with the editor, which means that when you double click the .cte file ,this file will be opened in the editor just like the notepad.
I know that Jbuider has used the JNI to achieve this way to open a project. So, will you kindly tell me the details about this technique or give me some document? My E_Mail is [email protected]
Best Regards,
Maria

I think this can be done from a batch file which you can execute when you install your application.
There are two commands which you are interested in, and they are:
assoc - Displays or modifies file extension associations.
ftype - Displays or modifies file types used in file extension associations.
You should use assoc to associate an extension with a file type, and ftype to associate the file type with an application.
E.g. jar is associated with this on my machine:
.jar=jarfile (from assoc)
jarfile="C:\Program Files\Java\jre1.5.0_06\bin\javaw.exe" -jar "%1" %* (from ftype)

Ok, let's see. Write the following class:
public class Grunt {
public static void main(String[] args) {
System.out.println("Hello Mars");
}Save it as "C:\Grunt.java", compile by typing:
javac c:\Grunt.javaRun by typing:
java -classpath "C:\" GruntDoes it say "Hello Mars"? If yes, go back to your program and compare for differences (maybe you used the "package" statement?).

Running a java program via a batch file

I am unable to run a java program from a batch file that I created.
spiderpackage.EntryPoint is a class file which I am trying to run with a -v option to output something.What should I do to get the output?
echo ^<html^>^<body^>
echo hello^<br^>
call java spiderpackage.EntryPoint -v
echo ^</body^>^</html^>

This has nothing to do with java programming. Have a look at the windows help for the call command.
The echo <html> stuff doesn't make sense. What's it for?
The command in you batch file should be:
java -cp . spiderpackage.EntryPoint -v
assuming that java is in the system path, and the EntryPoint.class is in a directory called spiderpackage which is a subdirectory of your current working directory

Running a Java program at startup in Linux

Hello
How do I run a Java program at startup in Linux? I know in Windows I can put a .bat file in C:\Windows\Start Menu\Programs\StartUp\ directory, but in Linux I have no idea how it is done.
Thank you,
Mihai

This is really a Linux question, not Java.
And then it depends on the version of Linux you are using.
Maybe this will help, otherwise you should try on a forum for your version of Linux.

Running a java program in a directory other than the current directory

How do I run a java program that's located in a directory other than the current directory?
There is a file Test.java in /dir1/subdir1. If my current directory is anywhere other than that directory, say /dir2/subdir2, I can compile Test.java by using:
javac -classpath /dir1/subdir1 /dir1/subdir1/Test.java
But when I try to run it with:
java -classpath /dir1/subdir1 /dir1/subdir1/Test
I get a java.lang.NoClassDefFoundError: \dir1\subdir1\Test
Any thoughts?

You need to specify just the name of the class you want to run. So java -classpath /dir1/subdir1 Test
