A DESCRIPTION OF THE PROBLEM :
There is no possible way of using FileOpenService.
Any combination of arguments to the FileOpenService
openFileDialog() method fail with access denied.

Yes. I have spent many hours on this since I submitted the bug report. I now
know why it works for you and fails for me. What is broken is not only the
FileOpenService, and FileSaveService, but potentially anything that triggers
JWS to bring up a Security Dialog. Below is a more detailed explanation,
along with some code samples you can use to reproduct the problem. Also
included are similar Sun bug reports and why those fixes do not apply.

Username Dietz (is he one of the JWS developers?) in Sun's Java Web Start
forums mentioned that when JWS brings up a Security dialog JWS starts up a
separate AppContext. This may be the whole problem. Apparently JWS does this
so no 3rd party look and feel could take control of the security dialog and
automatically (or secretly) select "Yes". Pretty smart! However, the new
AppContext may be running in a separate ClassLoader, or perhaps it is
resetting the UIManager ClassLoader property to ensure the default Metal look
and feel runs the security dialog and forgets to set the UIManager
ClassLoader back.

As you see from the exception, the 3rd party look and feel code is getting
access violations because _I suspect_ it is running in the wrong ClassLoader.

I have tried many ways of setting the UIManager ClassLoader property, even
forcing the UIDefaults properties to map the 3rd party registered
UIComponents to class files instead of string names (so UIManager will not
use Class.forName()) but this fails too.

Here is the code you need to reproduce the problem: Insert it before you use
the FileOpenService

ClassLoader jwsClassLoader = this.getClass().getClassLoader();
UIManager.put("ClassLoader", jwsClassLoader);
SlafLookAndFeel slaf = new
SlafLookAndFeel("com.memoire.slaf.SlafLookAndFeel");
UIManager.setLookAndFeel(slaf);

You can find slaf (any 3rd party look and feel will fail) at:
http://www.memoire.com/guillaume-desnoix/slaf/

I tried to set the UIDefault component mappings like this:
            // This doesn't work
            // http://www.gargoylesoftware.com/papers/bug12b4classloader.html
            Hashtable tb = UIManager.getDefaults();
            tb.put("ClassLoader", jwsClassLoader);
            Enumeration e = tb.keys();
            while (e.hasMoreElements()) {
                Object obj = e.nextElement();
                if (! (obj instanceof String))
                    continue;
                String k = (String)obj;
                if (k.endsWith("UI")) {
                    Class uic;
                    try {
                        uic = jwsClassLoader.loadClass(tb.get(k).toString());
                    } catch(Exception ex) {
                        // classnotfound...
                        continue;
                    }
                    tb.put(uic.getName(), uic);
                }
            }

But it didn't work. I'm pretty sure it's because of the AppContext issue I
described above. Likely someone familiar with the JWS internals and how it
uses AppContext would be able to confirm this in 5 minutes.

Since this bug means no 3rd party look and feel can work reliably in JWS (if
the FileOpenService/FileSaveService (others?)) are used I hope this bug can
be made a high priority.


REGRESSION. Last worked in version 1.0.1

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Get the FileOpenService
2. call its openFileDialog() method.
3. Click 'Yes' to allow permission to the FileChooser
4. Watch the exception.


EXPECTED VERSUS ACTUAL BEHAVIOR :
I expected to be able to browser the hard drive. What
happened is the FileChooser gets access denied exceptions.
