在終端cd到netbeans下載放置的目錄，輸入./netbeans-6.1-javaee-linux.sh，出現了找不到jdk錯誤信息：

Configuring installer...

Search JVM on the system...

Java SE Development Kit (JDK) was not found on this computer

JDK 6 or JDK 5 is required for installing the NetBeans IDE. Make sure that the JDK is PRoperly installed and run installer again.

You can specify valid JDK location using --javahome installer argument.

To download the JDK, visit http//java.sun.com/javase/downloads

在Ubuntu下已經安裝了JDK5和JDK6，怎么會一個都找不到，難道是兩者同時安裝了對netbeans有沖突，使得netbeans一個都找不到，或不知道使用哪一個jdk。

幸好提示信息里有個使用 --javahome 安裝參數指定JDK安裝位置

接著在終端輸入 ./netbeans-6.1-javaee-linux.sh --javahome /usr/lib/j2sdk1.6-sun

安裝向導窗口正常跳出。
