JLink share kernel from multiple Java Applications

While one can use the ShareKernel[] call within mathematica to share one 
kernel with multiple front-ends as explained in 
http://support.wolfram.com/mathematica/mathlink/general/sharekernel.html, 
I cannot find anywhere any info how to share a kernel that was started 
by one instance of a Java App front end via a standard 
MathLinkFactory.createKernelLink(...) call, and then be discovered by 
another application or instance of the previous App to continue 
expression evaluation under the original kernel.

I have created Mathematica actors for the Ptolemy-II system 
(http://ptolemy.eecs.berkeley.edu/ptolemyII/) that open and close the 
kernel around the designated expression evaluation for the purpose of 
automating theory generation, but now I need a variant of these actors 
that exploit the same environment and that requires that they both 
access the same Kernel which makes it a special case of he problem I 
described in the previous paragraph.

I would enormously appreciate any help along these lines..
