gcj question.

["R. Clayton" <clayton@xxxxxxxxxxxx>]

I would like to run this code

  $ cat main.java
  import java.io.FileOutputStream;
  import java.io.ObjectOutputStream;

  class main {
    public static void main(String [] args) {
      try {
	final FileOutputStream output = new FileOutputStream("storage");
	final ObjectOutputStream objectOut = new ObjectOutputStream(output);
	final widget w = new widget();
	objectOut.writeObject(w);
	}
      catch (Exception e) { System.err.println(e + " excption caught."); }
      }
    }

  $ cat widget.java
  import java.io.Serializable;
  import java.util.LinkedList;

  public class widget
  implements Serializable {
    }

  $ 

under gcj but am not having much luck:

  $ echo $CLASSPATH

On the other hand, java handles it:

  $ rm -f *.class storage

  $ javac *.java

  $ java main

  $ ls -l storage 
  -rw-r--r-- 1 clayton clayton 27 Jan 17 17:27 storage

  $ java -version

I have not yet discovered a useful google query for this problem.  What is a
more direct pointer to more information or, better yet, a description of this
problem and its fix?
