Java is not working with netbeans IDE 7 on ubuntu 11.10
提问by Vipin Kr. Singh
I am using Netbeans IDE 7.1.1 on ubuntu 11.10, when I try to create JAVA project using File-> New Project-> JAVA Project-> JAVA Application, it shows me the following error:
我在 ubuntu 11.10 上使用 Netbeans IDE 7.1.1，当我尝试使用 File-> New Project-> JAVA Project-> JAVA Application 创建 JAVA 项目时，它显示了以下错误：
The JDK is missing an required to run some NetBeans modules. Please use the --jdkhome command line option to specify a JDK installation or see http://wiki.netbeans.org/FaqRunningOnJrefor more information.
JDK 缺少运行某些 NetBeans 模块所必需的。请使用 --jdkhome 命令行选项指定 JDK 安装或查看http://wiki.netbeans.org/FaqRunningOnJre了解更多信息。
So I used the following command
所以我使用了以下命令
sudo update-alternatives --config java
and the result was:
结果是：
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 auto mode
1 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 manual mode
* 2 /usr/lib/jvm/java-7-openjdk-i386/jre/bin/java 1051 manual mode
I tried to run through terminal using the following command:
我尝试使用以下命令通过终端运行：
netbeans --jdkhome /usr/lib/jvm/java-7-openjdk-i386/jre/bin/java
but I got error:
但我有错误：
Cannot find java. Please use the --jdkhome switch.
and netbeans doesn't start as well.
并且 netbeans 也不会启动。
I tried this command using every path which I found through this command also:
我还使用通过此命令找到的每个路径尝试了此命令：
whereis java
but every time I got the same error and netbeans doesn't start.
但是每次我遇到相同的错误并且 netbeans 都无法启动时。
in netbeans config file (/usr/local/netbeans-7.0/etc/netbeans.conf) jdkhome path is :
在 netbeans 配置文件 ( /usr/local/netbeans-7.0/etc/netbeans.conf) 中 jdkhome 路径是：
netbeans_jdkhome="/usr/lib/jvm/java-7-openjdk-i386/jre"
when I tried to run netbeans using this path through this command:
当我尝试通过以下命令使用此路径运行 netbeans 时：
netbeans --jdkhome /usr/lib/jvm/java-7-openjdk-i386/jre
netbeans runs but when try to create project the same JDK missing error is displayed.
netbeans 运行但是当尝试创建项目时显示相同的 JDK 丢失错误。
One interesting thing also I encountered, if I use Eclipse every thing goes fine, I am able to create projects in eclipse and programs run smoothly. Eclipse doesn't show any wanning or errors like JDK is missing.
我还遇到了一件有趣的事情，如果我使用 Eclipse 一切顺利，我可以在 Eclipse 中创建项目并且程序运行顺利。Eclipse 没有显示任何 wanning 或错误，例如缺少 JDK。

I use Netbeans 7.1 on Ubuntu 11.10 and it works great, I didn't need to specify anything extra to get the JDK working. Here is my update-alternatives:
我在 Ubuntu 11.10 上使用 Netbeans 7.1 并且它工作得很好，我不需要指定任何额外的东西来让 JDK 工作。这是我的update-alternatives：
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 auto mode
* 1 /usr/lib/jvm/java-6-openjdk/jre/bin/java 1061 manual mode
How did you install Netbeans 7.1? As far as I remember it is not in the repositories. I used the GUI Swing installer from the Netbeans website. I installed it as a usernot using sudoor su.
你是如何安装 Netbeans 7.1 的？据我所知，它不在存储库中。我使用了 Netbeans 网站上的 GUI Swing 安装程序。我以不使用或的用户身份安装它。sudosu
Also check how you runNetbeans, try going to NETBEANS/binfolder and running ./netbeans.
还要检查您如何运行Netbeans，尝试转到NETBEANS/bin文件夹并运行./netbeans.

Hi Vinay, I have come across the solution which will work on any version of Ubuntu definitely keeping other java versions intact.
嗨 Vinay，我遇到了可以在任何版本的 Ubuntu 上运行的解决方案，绝对可以保持其他 Java 版本的完整性。
For this, please download tar.gz version of Java from Oracle website.
为此，请从Oracle 网站下载 tar.gz 版本的 Java 。
Suppose, your jdk installation tar file at location
/home/don/don@ubuntu ~ $
tar zxf jdk-7u45-linux-i586.tar.gzdon@ubuntu ~ $
sudo bash[sudo] password for don:
ubuntu ~ #
mv /home/don/jdk1.7.0_45/ /usr/lib/jvm/ubuntu ~ #
cd /usr/lib/jvm/ubuntu jvm #
update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0_45/bin/java 3ubuntu jvm #
update-alternatives --config java
假设，您的 jdk 安装 tar 文件位于
/home/don/唐@ubuntu ~ $
tar zxf jdk-7u45-linux-i586.tar.gz唐@ubuntu ~ $
sudo bash[sudo] 唐的密码：
ubuntu~#
mv /home/don/jdk1.7.0_45/ /usr/lib/jvm/ubuntu~#
cd /usr/lib/jvm/ubuntu jvm #
update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0_45/bin/java 3ubuntu jvm #
update-alternatives --config java

Done !!
完毕 ！！
Now, the turn of netbeans.
现在，轮到网豆了。
I assumed your file is saved at location /home/don.
我假设您的文件保存在位置 /home/don。
On netbeans installation file, right click -> properties-> permissions-> Allow executing file as a programunder Execute attribute.
在 netbeans 安装文件上，右键单击 -> properties-> permissions->Allow executing file as a program在 Execute 属性下。
Now click on installer, select run when asks for action and your installation will start without any hassles.
现在单击安装程序，在要求操作时选择运行，您的安装将开始，没有任何麻烦。
Happy programming !!
编程快乐！！
