sudo apt-get install poppler-data

install java runtime on ubuntu 10.04

1. Install the following packages:
sun-java6-jre
sun-java6-fonts
sun-java6-bin

2. Install imagej

3. Install jabref

The above two packages are subject to some font problems of chinese characters.

ps. Do not install this one ia32-sun-java6-bin or other java distribution. To my own case, these packages just mess up with chinese font.
