    Default JavaCompilerobject giving an error WITHOUT ide

    I am writing a program, where i need to compile one java file from within another, on the fly.

    the code is correct, and is working correctly under BlueJ. but when i export a jar file, or run it from the command-line, it gives me a null-pointer exception!! PLS HELP!!!

    JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
               if(compiler.run(null, null, null, "Hello.java")
               {}
               else
               {}

    it gives me a null-pointer exception
    Its tough to give any advice given the code posted and a lack of any stack trace that references said code. Recommend you post an SSCCE which clearly demonstrates the problem.
