Re: resource URLs broken in JWS

Doug Zwick wrote:

There is a subtlety about this when using WebStart. JWS uses its own ClassLoader instance to load classes from the resource JARs, and the default loader to load the Toolbox (and other classes from the BOOTCLASSPATH). This may account for the problem. When the resource bundle is in a JNLP resource JARs, you should use the JWS ClassLoader to fetch them. To do this, use one of your own classes instead of Toolbox, obtain its class loader, and use that to fetch the resource:

The 'Toolbox' class I use is my own class (com.bardac.dw1.tools.Toolbox), not a system class (in fact, I'm not aware of any system class called 'Toolbox').

In general, I'd use the following, unless there's a good reason not to and you're taking a null ClassLoader possibility into account.

rslt = this.getClass().getResource(name);

I vaguely remember that there was a reason to use the ClassLoader rather than the Class, but it's lost in the mists of my memory. I guess I can try changing the code and see if it makes a difference, even if the chances are small - having most of our Mac users dead in the water without a workaround isn't pleasant.


Thanks, Nick
