Compile a Java file... with a Java program
compilation, java
Solution
In Java 6 and onwards there is an API to use the compiler. This might be what you are looking for.

http://docs.oracle.com/javase/6/docs/api/javax/tools/JavaCompiler.html
Note that you need a JDK to have the compiler available. JRE will not be enough. If that is a problem consider embedding the Eclipse Java compiler in your application.
Problem
Is it possible for a program written in Java to compile a file using the JDK compiler (aside from using Java to open command prompt and throw the "javac" command at it to compile the file)?
