Question

我试图在Ubuntu 13.04中将ej（Kepler）中的MPJ Express集成在一起

.bashrc中定义的环境变量如下：

export JAVA_HOME=/home/soumya/Work/jdk1.7.0_25
export PATH=$PATH:/home/soumya/Work/jdk1.7.0_25/bin    
export MPJ_HOME=/home/soumya/InstalledSoftwares/mpj-v0_38
export PATH=$PATH:$MPJ_HOME/bin

问题1： 当我启动Eclipse时出现错误：

A Java Runtime Environment (JRE) or Java Development Kit (JDK) 
must be available in order to run Eclipse. No Java virtual machine 
was found after searching the following locations: 
/home/soumya/Work/eclipse/jre/bin/java java 
in your current PATH

通过复制Eclipse文件夹中的jre文件夹解决了这个问题。所以现在Eclipse开始了。

问题2： 我似乎无法运行多核计划。在我的Java项目的运行配置中，我完成了以下操作：

将变量MPJ_HOME设置为/home/soumya/InstalledSoftwares/mpj-v0_38
将环境变量MPJ_HOME设置为${MPJ_HOME}
将VM参数设置为-jar ${MPJ_HOME}/lib/starter.jar

但是当我运行该程序时，我收到以下错误：

MPJ Express (0.38) is started in the multicore configuration
java.io.IOException: Cannot run program "java" (in directory "/home/soumya/Work/EclipseWorkspace/SoftwareArchitectureProject/MulticoreDebuggerDemo"): error=2, No such file or directory

无法运行程序“java”（在目录中）
