This is an Eclipse / Ant question by way of James Elliott's "Hibernate
Developer's Notebook".
The book has several build.xml files. When I run the first one from a
command prompt, I can get it to work (took a day, but it works).
When I run it within Eclipse, however, I get the error message below. The
class it's referring to must be at least the second one it tries to load
however, because I used to get error messages about a missing
org/hsqldb/util/DatabaseManager.
I got that problem to go away so now a GUI loads. Then I get this message.
But as you can see from the names, they're both underneath the same top
level package. And both files are in their appropriate directories.
Anyone have a suggestion what's going wrong?
BTW, my "External Tools" configuration for this Ant run DOES point to the
hsqldb/classes directory (pointing to the .jar completely did not work).
Thanks
