  Listing for SimpleCompileTest.java that compiles the MyClass.java file.

  SimpleCompileTest.java:

  package test;
  import javax.tools.*;
   public class SimpleCompileTest {
  public static void main(String[] args) {
   String fileToCompile = "test" + java.io.File.separator +"MyClass.java";
   JavaCompiler compiler = ToolProvider.getSystemJavaCompiler(); //Line 6
   int compilationResult =  compiler.run(null, null, null, fileToCompile);
            if(compilationResult == 0){
        System.out.println("Compilation is successful");
    }else{
        System.out.println("Compilation Failed");
    }
}
}

I am compiling SimpleCompileTest.java and getting this error. HELP!!!

Have you tried debugging it? You can also provide the code with line numbers - the stack trace points to line 6. — LastFreeNickname, Feb 06 '14 at 11:01

@rick: There *is* a solution. Run the program with a JDK instead of a plain JRE. — Holger, Feb 06 '14 at 12:48
