Hello

I have a class name. How can I determine in which bundle it is declared?

TIA

Hi Chris,

PackageAdmin does this.

Hi Simon,

Thanks for interest.

I think I have not made it clear enough - I have class *name*, which is
String type. And PackageAdmin takes Class as a paremeter...

Yep -- misunderstood what you were looking for.
You can work backwards from the classes package name to find the set of
bundles that export them.
Try PackageAdmin's --
public ExportedPackage[] getExportedPackages(Bundle bundle)

I meant...
public ExportedPackage[] getExportedPackages(java.lang.String name)Gets the
exported packages for the specified package name.

Simon,

exported packages are packages contained by bundle, or defined as exported?

Just those defined as exported. ;)
I think you'll have a hard time getting at the other packages -- no metadata
to be had.

You can't. You get a .class, and then it figures it out. If you can't get a class, you don't have a dependency on that bundle.

There is always the brute force way:

You get all installed bundles and use Bundle.loadClass() to find the
class. Then use PackageAdmin.getBundle(Class) to find the bundle.

So, Daniel, what exactly are you trying to accomplish?
