Hi Manju,
Welcome to the project! Great to hear you're interested in jdb.
Yes, as you have noted in your other mail, we have an implementation of
jdwp under the jpda source folder. This is a native code implementation
of the jdwp standard, and covers most of it's features. We also use the
Eclipse JDI (Java Debugging Interface) to provide Java debugging hooks,
which I believe is packaged up into our tools.jar at build time. I would
personally recommend using JDI to implement the debug functionality of
jdb, as it provides a well spec'ed [1] Java API for you to use, will
allow you to create platform portable Java code for the debugger and
should also plug easily into our existing launcher (so creating a jdb
executable should be very simple).
To begin with I would recommend looking at the JDI spec - it should
provide everything you require API-wise (it's what Eclipse uses for
debug :) ), and will be a good starting point for you to think about
implementation of the tool.
Regards,
Oliver

Hi,
I am interested in putting together a proposal for developing some of the
tools needed for Harmony SDK.
I am particularly interested in the jdb tool development.
I am searching for a framework implementation that can allow me to connect
to the VM to be debugged
from a debugger process. Do we have this in place or are we required to
build up the debugging architecture
in order to proceed? Please give me some pointers so that I can do a source
code search in the right places.
