title: 'Hot code replace' not working -- Eclipse doesn't change any code on JBoss
body: <p>I'm currently experiencing a problem with 'hot code replace' not working on Eclipse Galileo and JBoss 4.2.3.</p>
  
  <p>Among other applications I'm running an exploded Java WAR on my local JBoss. The project from which it is build is managed by Maven. I build the project using the Maven goal war:exploded and then I copy that directory to JBoss with an ANT script.</p>
  
  <p>When I'm now running the application and set a breakpoint anywhere in the code, Eclipse properly halts at that line in the debug mode.
  But when I'm making a change to the source file and save it, Eclipse doesn't apply this change to the JBoss.
  For example, when I make a normal code line into a comment, the debugger still steps over this comment as if it was regular Java code. Or when I remove a line, the debugger seems to get out of sync with the file and starts stepping over parenthesis.</p>
  
  <p>But I'm not getting any 'hot code replace error'-messages either. It seems to me that Eclipse applies the changes to the source files, but doesn't apply it to the JBoss.</p>
  
  <p>Are there any special preferences that have to be turned on in order to make hot code replace work? Or are there any mistakes in how I build and deploy the application to the JBoss?</p>
