Subbu:
Looking though your embeddor code you are basically setting up an empty
kernel. In particular, on the following lines you are creating the
default kernel factory criteria and using this without qualification to
construct the kernel.
criteria = factory.createDefaultCriteria();
m_kernel = factory.create( criteria );
The difference between the above the cli example is that the cli example
qualifies a lot of criteria parameters. The absence of any criteria
modification suggests that you are declaring everything within you
merlin.properties file.
However, in your email from the 27th, you have included the info trace
which provides a summary of settings of the kernel (derived from the
criteria supplied to the factory) and they show that you have not
declared any block deployment targets.
In particular ...
> ${merlin.deployment} ==
If you compare this to running your example from the command line with
the -info option you will see that the 'merlin.deployment' property is
pointing to something concrete. You can update you merlin.properties
files with something like:
merlin.info = true
merlin.debug = true
merlin.deployment = tahiti.block
Or - you can get really adventurous and do this programmatically using a
facility.
If you have a moment come on over to #merlin on irc.freenode.net where a
bunch of merlin peeps (dev and users) are normally connected.
Cheers, Steve.
