Java: Error Unable to locate tools.jar

Saat compile kadang keluar error

Unable to locate tools.jar. Expected to find it in /usr/lib/jvm/java-6-openjdk/lib/tools.jar

Perbaikannya cukup sederhana

sudo apt-get update && apt-get install sun-java6-jdk
sudo update-alternatives --config java

Pilih

/usr/lib/jvm/java-6-sun/jre/bin/java
