Hi, I have a rather strange question..
I have a folder in my workspace, which contains some images. What I need
is a File-Array for these images. Inside my RCP, the following Snippet
does what I want:
URL url = FileLocator.toFileURL(bundle.getEntry("images"));
File f = new File(url.getFile());
File[] list = f.listFiles();
This doesnt work in RAP, I expect the problem to be the File located
absolute within the Filesystem, rather as a relative path, which may be
not allowed??
Can someone give me a snippet of how this works, I spent nearly half day
to this and now itŽs enough:-)
I know how it works for a single File, but not for this use case with a
directory containing files. For sure this is easy to solve, but I really
donŽt get the 3-lines at the moment.
Thanks for your help!

Hi,
what does bundle.getEntry( "images" ) return?

Martin,
just a wild guess -- have you tried the class
org.eclipse.core.runtime.FileLocator in the org.eclipse.equinox.common
bundle ?
If I remember correctly, the method #toFileUrl() converts an bundle://
url to a file:// url, which can then be used with a File object. I've
used that in the past.
Alternatively, maybe #findEntries(...) is helpful, but I'm not too sure.
Let me know if this helped.
Regards,
Elias.

Oops, sorry - I see you are already using file locator...

Hi,
I'm not sure what you're really intend to do. But if you want to load a
image from the bundle you may try
AbstractUIPlugin#imageDescriptorFromPlugin(String,String).
Opening an inputstream on a folder fails of course. But you can retrieve
the file handle to the folder from the URL and retrieve the children
from it. Each child that is not a directory can then be opened using a
FileInputStream.
Ciao

Hi,
IŽm quite sure there is a bug somewhere, the following snippet works:
Image im = Graphics.getImage("someNameForMyFile", new
FileInputStream(myFile));
Using Graphics.getImage(myFile) does not work and I get a "Invalid
Image..." Exception. The File definitely exists and is on the classpath.
In my opinion both cases should work.
