java webclient - sources and transferring browser canvas to other window

Hello,

my application is using the blackwood webclient. The embedded browser
by default is displayed in a separate JFrame (which works wonderfully)
but shall be embedded into a tab of the main window afterwards (e.g.
on user request).

The browser canvas resides on a JPanel, which then is put into the
JFrame. Removing the JPanel component from the JFrame component and
adding it to the tab of the main window will give me an empty tab.
However, I can see that this accomplished something, as resizing the
main window will generate messages like "[java] in
BrowserControlCanvas setBounds: x = 0 y = 0 w = 909 h = 743".

Same result when removing the browser Canvas from the JPanel holding
it and adding it to a new JPanel.

I assume I'm missing something rather obvious but currently I can't
figure out what's going wrong.

A completely different issue: Once my project is mature enough it
shall get deployed on Linux x86 and Solaris SPARC machines. The only
current downloads I see on the webclient project page are binary
releases for Windows and MacOS X. Can somebody point me to the source
code for the non-Java part so I can create builds for said platforms?

Thanks,

Maik Merten
