Hello all,
I spend some hours by checking out, how to locate files on my system for my
rcp app.
I've have RCP Project 'Test' and subdir 'icons'. My filesystem looks like
this:
Path.../Test/icons/icon.gif
Now, I want to get icon.gif with Java-I/O-File like this:
File file = new File(hello.gif);
The problem is, that Eclipse didn't get the Path of the Prject, but of
eclipse intall directory:
c:\programme\eclipse\hello.gif
What is the common way, to locate a file in my project path? And how to
locate files if I am exproting my rcp app as a product?
May be this is a newbie questions, but I've tried so much possible results
and no one of these results had worked...
Thanks a lot
florian

Hi,
opening files part of your rcp-projects is really simple. You simply call
InputStream i =
Platform.getBundle("com.my.project").getResource("/icons/icon.gif ").openStream()

Hi Tom and Florian,
You might also consider using FileLocator, as follows:
Bundle bundle = ClassLoaderTestsActivator.getDefault().getBundle();
Path path = new Path ("ErpPersistence.jar");
URL url = FileLocator.find (bundle, path, null);
InputStream inputStream = url.openStream();

normally your bundle is a jar file ... the URL that is returned from
getResource(*) would allow you to get an InputStream to that resource
without having to worry about where it is.
Remember, you should consider plugins and their directories and files
read-only when developing your plugin.
What are you trying to do? If you build a small number of files into a
directory and don't want to programmatically keep the list, you can use
Bundle#getEntry(*) to get the directory and then
FileLocator#toFileURL(url) to get it as a file:// url. This has the
advantage that if your plugin is delivered as a JAR, it will expand the
directory and contents for you (with the associated performance hits).
If you need a configuration directory then you probably need a different
approach.
Later,
