[Bluej-discuss] Error message in BlueJ launch

[Todd Whittaker]

All,

For the sake of closure on the list (and in case anybody in the future
is searching the archives for this same problem) Davin's suggestion
below fixed the student's problem.  He had already shut down his
firewall software, so I'm guessing that the "dt_shmem" parameter in
bluej.defs was the solution.

Thanks again,

Hi Todd,

It's hard to say for sure, but I suspect that some firewall software is

to blame for the "transport error" problem. Norton Internet Security or

ZoneAlarm are the usual candidates for this sort of problem, but it may

well be any other firewall software. Setting the "bluej.vm.transport" 
parameter to "dt_shmem" in the bluej.defs file will probably help; just

remove the '#' from the beginning of the existing line (which reads: 
#bluej.vm.transport=dt_shmem).

As for the duplicate CheckStyle extension, is it possible that he/she 
has two different versions installed at the same time?

Davin.
