Hi,
I ported my application to 3.0 M9 and changed my plugin class to work as
bundle activator. Anything works fine when starting a runtime workbench
from my development workbench. When I deploy my plugins to eclipse M9
itself and start my perspective I get the following log entries. Whats
wrong here?
Thanks in advance,
Dirk

Yes, it does. Here is the code snippet:
/**
* Constructor for LauncherPlugin.
*
*/
public LauncherPlugin()
{
super();
plugin = this;
//open the db login dialog (SWT)
[...]
}
Are there any problems with that one?

Hi Ted,
i moved the code. But the result is the same (same exception in log file).
The weird thing is: running my plugins via "Run->Run As->Run-time
Workbench" works properly but having them in my eclipse plugin directory
not. I cannot understand that...
New code snippets:
/**
* Constructor for LauncherPlugin.
*
*/
public LauncherPlugin()
{
super();
plugin = this;
}
/**
* Method start.
*
* @see
org.osgi.framework.BundleActivator#start(org.osgi.framework. BundleContext)
*/
public void start(BundleContext context) throws Exception
{
super.start(context);
//open the db login dialog (SWT)
DBLoginDialog login = new DBLoginDialog(Display.getCurrent(), new
Shell(Display.getCurrent()));
login.display();
}
