java - getting the error even after setting JAVA_HOME property

Question

This is the error that i get when i try to run the application based upon google app engine through netbeans. But i have set the JAVA_HOME variable :(see the pic)

BUILD FAILED
/home/non-admin/NetBeansProjects/Guestbook/nbproject/build-impl.xml:550: The following error occurred while executing this line:
/home/non-admin/NetBeansProjects/Guestbook/nbproject/build-impl.xml:300: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/jre"

Then why do i get the errors ?

Answer 1

在终端中导出环境变量仅限于您当前的终端会话。您应该编辑主文件夹中的.bashrc文件以获得永久解决方案。

Answer 2

如果您想继续使用 jdk1.7，请将 java home 添加到 /home/yourname/.bashrc 或 /etc/profile 文件 shell 代码：

export JAVA_HOME=/usr/java/jdk1.7.0_02
PATH=$JAVA_HOME/bin:$PATH

并运行“source .bashrc”命令。

如果只运行一次，请添加 env 参数。例如：

env JAVA_HOME=/usr/java/jdk1.7.0_02  mvn clean install
