Problem with invoking the javahelp from menuitem for multilanguage support

[Priyanka AGARWAL]

Hi,

I am using the following code to invoke the javahelp from my
application.
The code works fine

if (language is english){
sz_help_file_name = p_buf_application.get_sz_help_file_location() +
java.io.File.separator + "english";
URL hsURL = new URL ("jar:file:" + sz_help_file_name +
java.io.File.separator + "Campbell.jar!/Campbell.hs");
hs1 = new HelpSet(null, hsURL);
hb1 = hs1.createHelpBroker("introduction_htm");
hb1.enableHelp(mnu_help_topics, "introduction_htm", hs1);// Menu item
hb1.enableHelpKey(getRootPane(), "introduction_htm", hs1);//F1 key

ActionListener helper = new CSH.DisplayHelpFromSource(hb1);
mnu_help_topics.addActionListener(helper);
}else{
// same code for french but the helpset is different
}

Based on the language I am creating the helpBroker.
And invoking this function on change language functionality.
So whenever language is changed this piece of code is called.

But I have a problem when I want to switch between language from my
GUI.
Based on then language selected the help should also change.

I have created two helpsets for french and english.
The problem is with the menu item when I switch between language the
application crashes but it works fine with F1 key.

I am getting the following error message when I change the language
and click on the help Topics menu item.
