HTML files in runnable JAR [message #734477]

I am trying to package an HTML file in a runnable JAR.

My code to access the file:

URL url = this.getClass().getResource("XConManual.htm"); 
browser.setUrl(url.toString());

This works in Eclipse, but running the JAR file doesn't work.

To export, I go:
Export->Runnable JAR File (package libraries into generated JAR).

I noticed that url.toString() returns a path to my local drive where the HTML file is located.

What am I doing wrong?

As long as the HTML file is locatable on the classpath then
it should work. For a test to prove this, move the file to
the location of your class. Later if it's more convenient you
can use a path to locate it like "/the/html/classpath/file.html".

Unless your browser knows how to read and show an HTML file from inside a JAR file, it won't work inside a Runnable JAR. Perhaps you should clarify what you mean by "doesn't work"?

I'm not trying to use an external browser to read the HTML. I'm using an SWT browser widget within my application to display the HTML. Problem is that when deploying the runnable JAR, my application can't find the HTML file. When running it in Eclipse, the application finds it and displays it just fine.

I have the HTML file in the same directory as the .java files.

Ok I found an answer in another forum:

InputStream in = getClass().getResourceAsStream("XConManual.htm");
		Scanner scanner = new Scanner(in);
		StringBuffer buffer = new StringBuffer();
		while(scanner.hasNextLine()) {
		    buffer.append(scanner.nextLine());
		}

		browser.setText(buffer.toString());

Problem is that now the XConManual.htm can't find the image files and other files that it links to.
