在我的系统上,我无法运行启动进程的简单Java应用程序.我不知道该怎么解决.

你能给我一些如何解决的提示吗？

该计划是:

[root@newton sisma-acquirer]# cat prova.java
import java.io.IOException;

public class prova {

   public static void main(String[] args) throws IOException {
        Runtime.getRuntime().exec("ls");
    }

}

结果是:

[root@newton sisma-acquirer]# javac prova.java && java -cp . prova
Exception in thread "main" java.io.IOException: Cannot run program "ls": java.io.IOException: error=12, Cannot allocate memory
        at java.lang.ProcessBuilder.start(ProcessBuilder.java:474)

        at java.lang.Runtime.exec(Runtime.java:345)
        at prova.main(prova.java:6)

系统配置:
