I am working on an Mozilla Html Editor.
On Eclipse 3.4.1 (nsIWebBrowser)browser.getWebBrowser() works with no problems.
After moving to 3.5M6 (nsIWebBrowser)browser.getWebBrowser() always returns null, even though
the Mozilla Browser has completely loaded.
The Error seems to occcur when SWT.Browser calls ClassForName("org.mozilla.xpcom"), which returns null.
When I run the same Code as a Snippet in 3.5M6 (as in Snippet267) the call works fine though.
Is this a Bug? Thanks for any help.

As a test i put some of the SWT.Mozilla initialization code in my plugin:
try {
Class clazz = Class.forName ("org.mozilla.xpcom.Mozilla"); //$NON-NLS-1$
Method method = clazz.getMethod ("getInstance", new Class[0]); //$NON-NLS-1$
Object mozilla = method.invoke (null, new Object[0]);
method = clazz.getMethod ("getComponentManager", new Class[0]); //$NON-NLS-1$
try {
method.invoke (mozilla, new Object[0]);
} catch (InvocationTargetException e) {
}
} catch (ClassNotFoundException e) {
/* JavaXPCOM is not on the classpath */
} catch (NoSuchMethodException e) {
/* the JavaXPCOM on the classpath does not implement initialize() */
} catch (IllegalArgumentException e) {
} catch (IllegalAccessException e) {
} catch (InvocationTargetException e) {
}
and it works perfectly, only to immediately fail when calling
browser = new Browser(parent, SWT.MOZILLA | SWT.BORDER);
in the SWT plugin. Class.forName returning NULL.
How is that possible?

org.eclipse.swt.browser.Mozilla can't load org.mozilla.xpcom.Mozilla
because "DynamicImport-Package: org.mozilla.xpcom" is missing in the
MANIFEST.MF file.
There isn't a problem when using SWT out of OSGi (Snippet267, for instance).
The problem is fixed in the Eclipse trunk.

Thanks a lot for this information. I owe you one.
I will update and I hope that it will work.
