MyClass.java:

package test; public class MyClass { public void myMethod(){ System.out.println("My Method Called"); } }

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(); 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 executing the SimpleCompileTest class and getting a NullPointerException. The ToolProvider.getSystemJavaCompiler() is returning null. Can someone tell me what is wrong with the code
