I want to start my Swing GUI program in debug mode.
My Swing GUI program is started as follows:
Using the Microsoft Internet Explorer web browser, go to http://localhost:7001/proj/webstart/prog/ Then click a button to use Java Web Start to start my Swing GUI program.
How to start my Swing GUI program by Java Web Start with IE in Eclipse debug mode?
My Eclipse Platform is:
Build id: M20080221-1800
Java Web Start is just a mechanism for downloading and running a Java Application. That means that you debug a JWS application the same way you would any other Application and you don't need JWS at all for the development and testing of the Java code.
Once you have your application ready for production, you'd then deploy it to a web server along with the JWS .jnlp that describes it and debug the JWS download/install itself to ensure that your jnlp config info is correct.
An IDE is no substitute for an Intelligent Developer.
