[Communicator-user] Java bindings

[<nar...@te...>]

Dear Sam,

We, in the MUST project decided to use Galaxy as our intermodule
communication platform. Thanks very much for making such a valuble tool
available publicly. 

Basically, our  development language is C/C++. However, we would like to use
Java to develop some of the modules. 

We found that writing a Java based server is somewhat different to doing it
using C. Especially, we are concerned of the signature definition routines,
initSignatures, SigEntry, Signature and addSignature.  As I have understood
it, one has to define the exact nature of input and output frames for each
dispatch function of the server. However in our case we have two problems
regarding this,

1) Nature of the input/output frames are not known at the compile time. For
example we have frame formats such as

:no_of_parameters   N
:parameter1  some_thing
:parameter2  some_other_thing
.
.
.
:parameterN  some_thing_completely_different

The value of N is decided in the runtime.


2) Several different types of output (or reply) frames can be generated by a
dispatch function, depending on the information contained in the incoming
frame. (i.e. there is not a unique ouput frame for a given dispatch
function, as it is required by initSignature function)  

So my questions are:


1) Is our understanding above correct?

2) Is initSignature  absolutely necessary (No mention in the Java bindings
chapter of the manual)?

3) Is there any solution/work-around to the problems above (other than
changing the Frame formats or operational logic of the dispatch functions)?

I very much appreciate any clue !

Thanks in advance
Narada.
