Hi Chris,

The service wrapper doesn't have a libwrapper.so compiled for Arm so this

Suspected so. Yesterday was a plunge ahead and temporarily ignore
reality kind of day.
I have been developing my bundles (based on OSGi WireAdmin/Config Admin
services ) and have been testing them on a Karaf working in an 256M
Ubuntu CLI based virtualbox vm running on my intel dev machine. Karaf
is very cool and easy to work with and the docs are straightforward and
to the point. But now I need to move the virtual to the real world. I
hope to do it on the plug, but if I encounter too much friction I can
always go with a small intel based box as well.
I have a SheevaPlug coming next week so
I will certainly be doing something about this, but in the mean time if you
want to use the service wrapper you will have to get the native source for
Tanuki Service Wrapper 3.2.3 and set up a cross compiler for Arm on a Linux
machine.
Time permitting I may look into this. Thanks for the tip.
I know the Service Wrapper works well and there are a lot of features,
but is it possible to just start Karaf in the background?
I'll try to add this to Karaf some time in the next month or two.
That would be very good.
Just out of curiosity, other than the service wrapper is everything else
running OK?
So so...
The os shipping on the plug is somewhat of a hodgepodge and needs some
holes patched up to make it more usable.
See:
http://plugcomputer.org/plugwiki/index.php/New_Plugger_How_To
Even with the patches the plug is very slow to boot and starting Karaf
(until the prompt) takes around 25 seconds!
See also the intro of:
http://crichton.homelinux.org/~marc/eib_sheeva.html
My experiences, and the comments from the above blog writer, make me
think that a clean OS install is the way to go.
Also, are you running this on the ProSyst mBedded Server with
J9 or are you using Felix and have all of the Java bits installed manually?
There is a long backlog for shipping the plug so our earlier prototyping
was done on the sister product to the plug the OpenRD client. (A plug
mother board with lots of I/O options.) Then I used J9 and ProSyst
mBedded Server. (As you probably already know the ProSyst dev kit is
available as a buying option along with the plug. Price is ~$39. But
the ProSyst run times are evaluation only.)
But for Java, I prefer to work in SE JVMs and found the J9 Foundation
Profile too constraining. Although ProSyst marketing and support were
helpful, here too I prefer to work with a larger community based
OpenSource OSGi framework like Felix or Equinox.
As for now the Java on the Plug is an OpenJDK headless JRE. I simply
(after all the fixes noted above) installed a headless JRE on the plug
with a:
apt-get update openjdk-6-jre-headless
command.
happy holidays,
John
Thanks,
Chris

Any ideas or trouble shooting tips?
