I had some trouble to get jblogeditor to work through a proxy.
When I first tried it, I had it installed according to these instructions and then the appropriate settings were inherited
from Eclipse. After a bit of fiddling, I figured it out:
./jblogeditor -vmargs -Dhttp.proxyHost=proxy.... \ -Dhttp.proxyPort=81
Might have been obvious to someone with more Eclipse experience.
