Getting a bundles jar location [message #108609] Wed, 23 April 2008 16:12 Go to next message

Hello,

How can I get the absolute location of a bundle's jar file? I need to build
a FileInputStream out of it. I tried with :

bundle.getResource(bundle.getLocation())

but it doesn't return anything back. bundle.getLocation() returns something
like :

update@plugins/org.eclipse.ui_3.3.1.M20070910-0800b.jar

which seems to be an identifier. I don't know where to use it.

Thanks,
Boyan.

Hi,

I had similar problem. I need a InputStream on a Ressource in my Bundle.
It works with:
FileLocator.resolve(bundle().getEntry("relativePath"))

If you use:
FileLocator.resolve(bundle.getResource(bundle.getLocation()) )
it should work.

Hope that helps.

The correct way, should be:

FileLocator.resolve(bundle.getEntry("/"))

bundle.getLocation() returns unique string, identifying the bundle in
the framework. Before R4, the bundles didn't have symbolic names and
versions, the location was used for identifying a particular bundle.

The location of the bundle is usually an URL to the original bundle
contents, but the framework doesn't make an assumption about this. So,
the update.configurator is marking each bundle it is responsible for by
installing it with location starting with update@. The framework core
also does something like that by marking the bundles from osgi.bundles
property with initial@

Then I pass that one to a FileInputStream, I get an error. I don't think
that a simple cutting of the jar: part will work in the general case. I also
tried

FileLocator.openStream(bundle, new Path("\"),null)

but I also get an exception.

I would appreciate any other ideas?

Another thing that might work in the general case:

Platform.getInstallLocation().getURL().toString()+bundle.get Location().substring(7)

It does work on my computer. If bundle.getLocation() always starts with
update@ there should be no problem.

Using the code I suggested, will give an URL which points to the root of
the bundle. In case a bundle is .jar file, it will be jar: URL, pointing
to the root of the jar file (as you already know:). In case of directory
bundle, it will point to the directory containing the bundle. So, if you
get jar: URL, you need to extract the file: URL inside.

What question arise? why do you need to get the location of the bundle
and use FileInputStream on it? Are you sure there isn't a better
solution for your problem?

BR,
Danail

stream on the target eclipse, so the only thing I need is to be able to get
all the bundles I need as streams on the source eclipse. Basically the task
can be narrowed down to getting a jar or folder of a plugin as an
inputstream.

I did the thing you said and extracted the location of a jar (file:...), but
then I found that I can't read it. File.canRead returns false, so I can't
create and inputstream. I guess the same will happen with a plugin installed
in a folder.

Another method I though of is reading all the files in a bundle, packing
them as a jar in a temp folder and streaming that though http. Haven't tried
it yet though.

This is strange. If you extract the correct path, then File.canRead
should return true (how Eclipse itself reads this path). So, check that
the path you use for creating the File object is correct. If you have
trouble, can you post the:

- the result from FileLocator.resolve()
- the parameters to new File() or new FileInputStream()

Regarding the folders -> you'll need to detect and most probably need to
pack them before forwarding obviously:)
