Installing Java JDK on Ubuntu 10.04
提问by NullUserException
Ever since I upgraded my Ubuntu from 9.10 to 10.04 I can't start Netbeans any more, because apparently they are dropping support for Java's JDK in favor of OpenJDK. Well, problem is, my IDEs won't work with OpenJDK.
自从我将 Ubuntu 从 9.10 升级到 10.04 后，我再也无法启动 Netbeans，因为显然他们正在放弃对 Java JDK 的支持，转而支持 OpenJDK。好吧，问题是，我的 IDE 不能与 OpenJDK 一起使用。
apt-get install sun-java6-jdkis not working. I downloaded the Linux installation file from Sun (jdk-6u21-linux-i586.bin) and installed it, but I can't call java or javac from the terminal.
apt-get install sun-java6-jdk不管用。我从Sun下载了Linux安装文件（jdk-6u21-linux-i586.bin）并安装了，但是在终端无法调用java或javac。
Can anyone help me here?
有人能帮我一下吗？

The NetBeans installation has a reference to the JDK that is created at install time. After the upgrade to 10.04, that reference is no longer valid.
NetBeans 安装引用了在安装时创建的 JDK。升级到 10.04 后，该引用不再有效。
Go to the directory where you installed NetBeans. By default it is "/usr/local/netbeans-version" if you installed as root or "$HOME/netbeans-version" if you installed as a regular user. There will be a subdirectory named "etc". In that directory, edit the "netbeans.conf" file. Look for the netbeans_jdk_homeand change it to /usr/lib/jvm/java-6-openjdk.
转到安装 NetBeans 的目录。默认情况下，如果您以 root 身份安装，则为“/usr/local/netbeans- version”；如果您以普通用户身份安装，则默认为“$HOME/netbeans- version”。将有一个名为“etc”的子目录。在该目录中，编辑“netbeans.conf”文件。查找netbeans_jdk_home并将其更改为/usr/lib/jvm/java-6-openjdk。

You missed the final step: after installing the JDK manually (instead of from the package system), you need to add the bindirectory of your JDK to the PATH. The best way to do that in Ubuntu 10.04 is to edit the file /etc/environment: sudo nano /etc/environment. Log out and back in and you should be able to run Java.
您错过了最后一步：手动安装 JDK（而不是从包系统）后，您需要将binJDK的目录添加到PATH. 在 Ubuntu 10.04 中执行此操作的最佳方法是编辑文件/etc/environment: sudo nano /etc/environment. 注销并重新登录，您应该能够运行 Java。
