If you want to use Dynamic Suiting for linking those packages:
1. Copy <CODEBASE> element in its entirely from you Java Runtime package's OSD
2. Create new <DEPENDENCIES> ... </DEPENDENCIES> element to JabRef's OSD file, under <IMPLEMENTATION> block
3. Paste your copied CODEBASE under this new DEPENDENCIES -element
4. Modify copied CODEBASE so that you add new attribute: MANDATORY="TRUE" to it
5. If you wish, you can remove unneeded attributes from that copied CODEBASE (FILENAME, PARAMETERS, SIZE) as long as you leave HREF and GUID as-is
6. Publish your modified JabRef
