I have just met a annoying problem with my java. I tried to install jre and jdk on my Ubuntu 12.04 but something must have go wrong. I can run java -version to see java version and javac -version to see javac version, even test java in chrome. But I can't run jnlp file. When I try to open it, nothing happens. What should I do now? Thank you.
