AW: [platform-core-dev] Getting the input stream for a resource- can't b

["Ploett Norbert" <norbert.ploett@xxxxxxxxxxx>]

Tom,

I did not try the URL returned by Platform.find() directly because it contains a bundleentry: protocol specifier and I did not expect that a standard java.net.URL can make anything out of that.

But to my surprise it does work which means that I do not know enough about how an URL resolves it's path in general and in the eclipse context.

Thanks for your advice


Norbert

Peter's suggestion will only work if you have "." on the Bundle-ClassPath.  You can also try: 

  Bundle b = Platform.getBundle(PLUGIN_NAME);
 URL url = Platform.find(b, new Path(path)); 
  InputStream is = null; 
  if (url != null) 
    is = url.openStream(); 

Did the url from Platform#find not work unless you resolved it?  Questions like this should be posted to the news groups. 

Tom.
