OS X 10.5.5, Java 1.5.0_16 , Eclipse 3.4., Designer 6.8.0

[IT2BE]

I have the following setup:

OS X 10.5.5,
Java 1.5.0_16 ,
Eclipse 3.4.,
(Swing) Designer 6.8.0

Before I used Eclipse 3.3 and Designer 6.7

SWT and GWK Designer works perfect.

Swing Designer never worked.

The issue reported is:

Operation failed: com.swtdesigner.properties.PropertyException: java.awt.HeadlessException <component: progress class: ProgressStatusBarItem>.

Part of the log is below.

The issue appeared (this time) with a fresh install (today) of Eclipse and plugins. It does not matter if I create a completely new class or use an existing one (this was an existing one).
One of the replies I received earlier to this issue is that it has to do with settings of the java.awt.headless property. I had to set it to false.
So that is what I did in the Eclipse ini file: '-Djava.awt.headless=false' but that does not help either.

I read about people working with Swing Designer on OS X and I want to do that to.

Until now I use JFormDesigner but I really like the way Swing Designer works much more...

Any suggestions?

[Alexander.Mitin]

This is weird, since the (according to sources) 'headless' variable value determined using 'os.name' and 'java.awt.headless' properties. Default value is false.

Code: Select all

                    String nm = System.getProperty("java.awt.headless");
                   
                    if (nm == null) {
                        /* No need to ask for DISPLAY when run in a browser */
                        if (System.getProperty("javaplugin.version") != null) {
                            headless = defaultHeadless = Boolean.FALSE;
                        } else {
                            String osName = System.getProperty("os.name");                       
                            headless = defaultHeadless =
                                Boolean.valueOf(("Linux".equals(osName) || "SunOS".equals(osName)) &&
                                                (System.getenv("DISPLAY") == null));
                        }

So any more help other than letting us know this is "weird"?

This is pretty simple. The following exception indicates that the headless flag is set in the Eclipse startup (probably in the eclipse.ini file)...

Code: Select all

There was a time a couple of years ago that any Swing references in a plugin would cause Eclipse on the Mac to lock up. Adding the headless option was the work around. That problem was solved by the time Eclipse 3.3 was released, if I recall.

Obviously, Swing Designer (or any other Swing related plugin) will not run with that in effect.
