Hello Ben,

Virgo is based on Equinox, and I have personally run Vaadin on Equinox
many times. So although I haven't tried running on Virgo, I would be
very surprised if it didn't work.

If you are experiencing a problem then you need to describe it in full.

Cheers,
Neil

Hello Neil,

The current problem with Virgo is, that you cannot deploy PDE based
Plugin-Project directly. You would have to pack them into real OSGi-
Bundles and deploy them to Virgo.

but i have any idea about that.
Cheers,
Arbi

Sorry but this sounds like a problem you should ask about on the Virgo
mailing list.

However as a hint, you can build PDE projects as real bundles by
clicking File menu -> Export -> "Deployable plugins and fragments".

Neil

I tried to export all project in this demo :
com.siemens.ct.osgi.vaadin.pm and deply there with no error in pickup
of virgo but when i test it in browser with the same URL in Equinox
exemple (http://localhost:8080/com.siemens.ct.osgi.vaadin.pm.main) I
have 404 not found.

Hello,
Great news, I have turn a simple exemple of dynamic bundles in Virgo.
I had follow this tutorial (https://vaadin.com/wiki/-/wiki/Main/
Creating%20a%20Modular%20Vaadin%20Application%20with%20OSGi) and
making some modification. I will write a tutorial how to do this.

I test this exemple by a simple component like Label , it run
successfully but when i try with a component like VerticalSplitPanel ,
I have this Error in Virgo (ClassNotFoundException)

I understant that Virgo can't load this class but in my template.mf i
import bundle vaadin with version 6.6.4 but i have the same error.
I don't know how i can solve the problem.

Any suggestion ?

[Chris Brind]

Hi,

That's not exactly a ClassNotFoundException, it's a
NoClassDefFoundException, which means the class can be found but the
definition cannot be realised because some other class it depends on
cannot be found. See if you can work out what that class is (by
looking at sources perhaps) and make sure it's available at runtime.

Good luck

Cheers
Chris

I did some experiments with Kai Tödter's example on Eclipse Virgo. Finally, i had to do some modifications and then it works.

See here:

Maybe it helps you.
