How can i run this program from a jar.

Aug 23rd, 2006

I am using IBM Websphere, and from here i can just click Run As java application, and the program runs inside websphere. But i want to run the program outside IDE.

I created a jar file and everthing is correct with it. It has the MANIFEST.MF and all.

So what do i need to do to run this from cmd.exe? I would like cmd to open when the jar file is double clicked so that the program will use the command line as the input?

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
import java.io.*;	// Java I/O classes
public class L3P3
{
	public static void main(String []arg) throws IOException		// throws IOException
	{
		BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
 
		System.out.println("Enter in your full name");
		String s1 = input.readLine();
		StringBuffer tmp = new StringBuffer(s1);
		String s2 = tmp.reverse().toString();
 
		System.out.println("Your reversed name is " + "\"" + s2 + "\"");
	}
}
import java.io.*;	// Java I/O classes
public class L3P3
{
	public static void main(String []arg) throws IOException		// throws IOException
	{
		BufferedReader input = new BufferedReader(new InputStreamReader(System.in));

		System.out.println("Enter in your full name");
		String s1 = input.readLine();
		StringBuffer tmp = new StringBuffer(s1);
		String s2 = tmp.reverse().toString();

		System.out.println("Your reversed name is " + "\"" + s2 + "\"");
	}
}

Thanks, sj

ur has nothing to do with it. Java didn't exist when people were living there.

to make an executable jar, you need to provide the Main-Class attribute in the manifest file inside the jar.

As people are clearly allowed to attack me but I'm not allowed to defend myself, I no longer post to this site.
