Regarding Java Help System...('',)

Question

Hello All,
I had successfully implemented Java Help System for my chat messenger...
But the problem I am facing is.... after making a jar file of my helpsystem..I am trying to access my Helpset file from my java code....
When I click on Help topics button to display the Helpset It will give me the following error....
HelpSet: Could not parse
Got an IOException (null)
Parsing failed for null
HelpSet: Master.hs not found
Exception in thread "main" java.lang.NullPointerException
at HelpMenu.<init>(HelpMenu.java:30)
at HelpMenu.main(HelpMenu.java:63)
But I have placed that Jar file in my program....where all files are given....
Can anybody help me out here.....
Thanks in advance.....

Answer 1

I am using the following program to do so...
public class JavaHelpDemo extends JFrame
private HelpBroker someHelpBroker;
public JavaHelpDemo()
HelpSet hs;
try
        File f = new File("Master.hs");
        URL url = f.toURL();
        hs = new HelpSet (null, url);
        HelpBroker hb = hs.createHelpBroker();
        new CSH.DisplayHelpFromSource(hb);
        hb.setDisplayed(true);
      catch (Exception a)
        System.out.println("Error is here");
        System.out.print(a);
// constructor
public static void main(String[] args)
JavaHelpDemo javaHelpDemo1 = new JavaHelpDemo();
}//classActually my this program is running well and I m getting my helpset only when i insert all my files with htmls in my source path.....
I hav created a Jar or all these files and named it Help.jar
is there any way just to call that helpset using this jar without giving all files into source path.....
