Problems using the org.eclipse.wst.ws.internal.explorer package [message #484591]

Hi,

in my own plugin I open a web services explorer window via the
WSExplorerLauncherCommand class.
Therefore I added the org.eclipse.wst.ws.internal.explorer package to my
plugin dependencies.
My code looks as follows:

WSExplorerLauncherCommand wsec = new WSExplorerLauncherCommand();
LaunchOption lo = new LaunchOption(LaunchOptions.WSDL_URL,location);
wsec.setLaunchOptions(new LaunchOption[]{lo});
wsec.execute();

Now the surprising fact: Everything works fine, so the reason why I'm
bugging you is, that eclipse shows up warnings like "Discouraged access:
The type WSExplorerLauncherCommand is not accessible due to restriction on
required library..."
Since the org.eclipse.wst.ws.internal.explorer package exports those
classes to ohter plugins, I don't understand these warnings.
Is there any better, any correct way to access the mentioned classes? (I
dislike the solution with @SuppressWarnings("restriction"))

Thanks,
Bernd

Hi Bernd,

The WSExplorerLauncherCommand is exported to other plugins so it can be
used by other plugins within WTP, but it is not API. Specifically the
manifest.mf of the web services explorer has this line:
org.eclipse.wst.ws.internal.explorer;x-internal:=true which indicates
that it's not API.

You're getting the discouraged access warnings to warn you that what you
are using is not officially API. You can open an enhancement request in
bugzilla asking for this to be made public API for the WTP web services
team to consider.

That said, that class hasn't changed since 2005, and there are no plans
to change it anytime soon. You should be safe to use it

I found this document on the eclipse wiki which might be useful for you:

Hi ,
I am trying to invoke web service explorer in my plugin. I am getting NullPointerException on stateLocation defaultFavoritesLocation...
If i hard code those values i do get nullpointer on
wsec.execute();

as

Desperately need to sort this out.

public class Test {

public static void main(String[] args) throws Exception {

try{

String stateLocation = ExplorerPlugin.getInstance().getPluginStateLocation();
String defaultFavoritesLocation = ExplorerPlugin.getInstance().getDefaultFavoritesLocation();
WSExplorerLauncherCommand wsec = new WSExplorerLauncherCommand();
wsec.setForceLaunchOutsideIDE(true);
LaunchOption lo = new LaunchOption(LaunchOptions.STATE_LOCATION,"stateLocation");
LaunchOption[] launchOptions= new LaunchOption[] {
new LaunchOption(LaunchOptions.STATE_LOCATION,stateLocation),
new LaunchOption(LaunchOptions.DEFAULT_FAVORITES_LOCATION,defaul tFavoritesLocation)
};
wsec.setLaunchOptions(launchOptions);

wsec.execute();
