Are the imported packages of fragments included in the host bundle classpath?

[admin]

I have some problems regarding OSGi fragments and

Class.forName()

. The example below illustrates my problem.

I have a third-party bundle

Foo

. I cannot modify

Foo

in any way. The bundle contains the following class:

public class Serializer {
    public String summarizeClass(String className) {
        Class<?> myClass = Class.forName(className);
        ...
    }
}

If I call this method from bundle

Bar

for

org.myPackage.MyClass

, it will fail, since

MyClass

is not on the classpath of bundle

Foo

.

Can I simply add a fragment

Foo.fragment

with a dependency to

Bar

to modify the classpath of bundle

Foo

? Or does this dependency only apply for classes within the fragment?

Long story short:
What are the semantics of

Class.forName()

in OSGi, when executed in a class of the Host bundle? Does it include:

<ul>
<li>Q: The bundle classes? A: Yes.</li>
<li>Q: The classes contained in the fragment? A: Yes. <a href="http://olegz.wordpress.com/2008/11/05/osgi-and-classforname/" rel="nofollow">Source</a></li>
<li>Q: The imported packages and the packages exported from required bundles? A: Yes.</li>
<li><strong>Q: The imported packages and the packages exported from required bundles of all fragments? A: I don't know.</strong></li>
</ul>
