I'm trying to include JavaHelp inside my application developed under Eclipse.
I did the following things:
Added the following library's JARs to my project class path (Properties->Java Build Path->Libraries->Add External JARs
):
jh.jar
jhall.jar
jhbasic.jar
jsearch.jar
I tried to create both folder (New->Folder
) called help_folder and a Source Folder (New->Source Folder
) called help_source_folder, and put inside them a file of example called Master.hs (I took it from the JavaHelp archive).
Then from inside my application I did the following:
try {
ClassLoader loader = this.getClass().getClassLoader();
URL url = HelpSet.findHelpSet(loader, "Master.hs");
//alternatively : URL url = HelpSet.findHelpSet(loader, "help_folder/Master.hs");
//alternatively: URL url = HelpSet.findHelpSet(loader, "help_source_folder/Master.hs");
JHelp jhelp = new JHelp(new HelpSet(loader, url));
} catch (HelpSetException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Now the problem is the following: HelpSet object cannot be created because a null
URL is returned by findHelpSet()
method.
I have no idea on how solve this. Can someone put me in the right direction?
Make sure the folder you create is inside your project's source folder (defaults to 'src'). If it's not then it won't be included in the output folder (defaults to 'bin') when it builds the project.
