在Ubuntu 12.04中安装Java 5

问题描述：

我需要在Ubuntu 12.04中安装Java 5.无法通过apt-get做到这一点.

I need to install Java 5 in my Ubuntu 12.04. Can't do it by apt-get anymore.

从以下位置下载了.bin http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase5-419410.html 并安装它.

Downloaded the .bin from http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase5-419410.html and installed it.

不过，在执行以下操作后，jdk 1.5的选项不会出现: sudo update-alternatives --config java

Still, the option for jdk 1.5 doesn't appear after I do: sudo update-alternatives --config java

我做错了什么?我该怎么办?

What am I doing wrong? How should I do it?

谢谢.

答

看起来像是您弄错了.

对于使用update-alternatives，您必须通知它您拥有新的Java版本:

For using update-alternatives you have to inform it that you got a new java version:

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jre1.7.0_40/bin/java" 1
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/local/java/jdk1.7.0_40/bin/javac" 1
sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/local/java/jre1.7.0_40/bin/javaws" 1

并将该版本设置为默认版本:

And set that version as the default one:

sudo update-alternatives --set java /usr/local/java/jre1.7.0_40/bin/java
sudo update-alternatives --set javac /usr/local/java/jdk1.7.0_40/bin/javac
sudo update-alternatives --set javaws /usr/local/java/jre1.7.0_40/bin/javaws

此外，您可能要编辑/etc/profile 以将Java添加到PATH中，尽管Oracle安装程序可能已经为您完成了此操作.

Also, you may want to edit you /etc/profile to add java to the PATH, although maybe the Oracle installer already did that for you.
