误装jvm

才装ubuntu的时候一时偷懒输入的是sudo apt-get install java,随便选了他的几个包就安装了，后来发现安装的不是sun的jvm，特别悲剧，装了sun的，发现设置依然没有改变，网上搜了下，在这里找到了解决办法，终于修改好了。

以下是摘抄的解决办法

Run the command `java -version`. And if you get the following, it’s no good:
java version “1.4.2″
gij (GNU libgcj) version 4.1.2 (Ubuntu 4.1.2-0ubuntu5)

Just install the SUN java packages (using apt) and then run `update-java-alternatives -s java-1.5.0-sun`. When you run `java -version` now, you should read:
java version “1.5.0_11″
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03)
Java HotSpot(TM) Server VM (build 1.5.0_11-b03, mixed mode)

Now re-install eclipse and it will run like a charm.
