ubuntu系统jdk安装的默认路径

搜索ubuntu系统jdk安装的默认路径。

which javac返回/usr/bin/javacfile /usr/bin/javac

返回/usr/bin/javac: symbolic link to `/etc/alternatives/javac'

然后file /etc/alternatives/javac返回/etc/alternatives/javac: symbolic link to `/usr/lib/jvm/java-6-sun/bin/javac'

然后file /usr/lib/jvm/java-6-sun/bin/javac返回/usr/lib/jvm/java-6-sun/bin/javac: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.2.5, not stripped

到此为止，说明路径是/usr/lib/jvm/java-6-sun/bin/，在Eclipse里面设置即可。
