ClassLoading - how to make every class (in the visited project) accessible ?

[alwad]

Hello,

The context is using one's own addon in a second project. Say this addon manipulates all the @Path classes

As I was playing with code generation, I faced issues while trying to do Class.forName() because the addon has no knowledge of P2 classpath.

What I did is infer the file path of the sources and then use Roaster to get a JavaInterface.

But now, if I wanted to introspect (the java.lang.reflect way) a class declared in a dependency of this second project (like a class defined in twitter4j for example), how would I do ?

Should I loop on all JARs in the visited project then loop on all the JAR's .class entries and tell the classloader to load them ?

And same for target/classes ?

Or is it a special classloader that I haven't found ?

Cheers,

Jerome

Hi Jerome,

What do you mean by "P2 classpath"?

By all means, see if this addon helps you out:

Hello George,

By P2 I meant second project.

Context :

* 2 projects in the workspace, first is the addon, the second is where the addon is used, say a maven based webapp with jaxrs endpoints.

* My goal here is to generate SOAPUI xml out of the java interfaces that sport the JAXRS annotations

I used your addon in the simplistic way.

Definitely have to dig the question of scanners and do some tests to see if I can .

Cheers,

Jérôme
