I got a Myeclipse7, a ISO file.

So let’s begin to install it.

1. Make sure you use a sun jdk. besacuse a openjdk may not support or even lead some error.

sudo update-alternatives ——config java
you will get this:
选择        可选项
———————————————–
1    /usr/bin/gij-4.2
2    /usr/bin/gij-4.3
3    /usr/lib/jvm/java-gcj/jre/bin/java
+        4    /usr/lib/jvm/java-6-openjdk/jre/bin/java
*         5    /usr/lib/jvm/java-6-sun/jre/bin/java

要维持缺省值[*]，按回车键，或者键入选择的编号：
choice a sun jdk more than version 5, if there is no sun-jdk ,use apt-get to install one.

2 mount the ISO file.

sudo mkdir /media/me
sudo mount -o loop myeclipse7.iso /media/me

3 install it.

cd /media/me
./myeclipse-70-installer.

the first setp is very important, remeber it! That’s ALL.
