What do you mean "start" a JAR? If the JAR is an applet, then all you have to do is include <applet> ... </applet> tags.

No, you can't directly run a .bat file from an HTML page.

I have a jar file with different java files in it as a package. If i double click on the "test.jar" or if i execute that command line "java -jar test.jar" , it works fine.

but i need to start the file from a html page with a link or a button that should execute the jar file. The reason i want this is, there are many files and the user doesnot know which one to use. ( all the files are on the same computer and no internet is required)

How do i do this??

Please help me.

Best Regards

OK. From the sounds of that, it's not an applet, it's a Java (probably Swing) application.

You can't simply click on a link and it will run. If you click on a link to a JAR, a dialog will be displayed asking the user whether they want to 'Save' or 'Open' the file. However, if the user selects 'Open' (and Java is installed on the local machine), the JAR will be executed. Here's the HTML I used in my test:


<html>
	<body>
		<a href="JDBA.jar"> Click here </a>
	</body>
</html>

Why not just organise your folder hierarchy better (or provide short-cuts at the top-level of the hierarchy tree)?

I did exactly the same thing as above. But after i opened the jar file nothing is displayed in the application. How can i track runtime errors to find out what went wrong??

Is you application a Swing application (i.e. not an applet, but an application with a graphical front-end)?

If you saw nothing, I have a suspicion that your JAR contains a Java console application, in which case I don't think that you can do this. JAR files are typically opened with 'javaw' in windows, which suppresses the console. Therefore, if you try and run a JAR which contains a console application with 'javaw', all console input/output will be hidden!

You can check to see what kind of application your JAR is by simply double-clicking the JAR. If it appears that nothing happens, chances are that you've got a console application.
