Re: InstantDB: Re: Version 3.13 & Network Support using RmiJDBC


Bill

Apart from all of its own properties from the .prp file, the only system
property that I can find InstantDB trying to read is the java.vendor
property. All properties will be read by the DBBrowser utility unless you
edit its code to take them out.

As to the correct contents for the java.policy file - I think you're
probably leading edge on this one. Any info you do pick up would, I'm sure
be very useful to everyone else in this group.
