title: Running a Java Program in Grails
body: <p>I've written some small programs that help me out parsing/analysing data.</p>
  
  <p>I want to use those programs in my grails app.</p>
  
  <p>Regarding my research so far, it is possible, but I don't see where I have to place my Java Code to get it running. Are there any examples available? </p>
