/home/gyles19/jbproject/MyProject/src

And you have a source file in which there exists lines like:

  package com.visi.gyles19
  public class Foobar {
  ...
  }

Then the source file itself must be named

  Foobar.java

and the proper location for Foobar.java is:

  /home/gyles19/jbproject/MyProject/src/com/visi/gyles19/FooBar.java

This breaks down as:

  /home/gyles19/jbproject/MyProject/src/com/visi/gyles19/FooBar.java
  ..................................... <-- sourcepath
                          package -->   ................
                                               class --> ............

This is especially important when debugging. When the debugger attempts to display a source file, it takes the class file's package, converts it to a platform path (ie com.visi.gyles19 becomes com/visi/gyles19) and then appends the class name (to make it com/visi/gyles19/Foobar.java)

Java internally converts the "." characters within your package statement into the file.separator characters specific to your platform, ie "\" on Windows/Dos and "/" on Unix.

It then goes through the project source path appending the converted package path to each source path provided until it finds the Foobar.java file.

If Foobar.java is in the wrong place, the debugger will never find it. The #908 compiler error is another symptom of a misplaced source file.

Rule: .class and .java files must always be placed in directory locations which reflect the package statement inside the .java file.

In the above case, the MyClass.java file contains a 'package MyPackage;' statement, but it is incorrectly located in directory 'untitled1'.
