Added: varia/src/main/org/jboss/varia/autonumber AutoNumber.java
AutoNumberEJB.java AutoNumberEJB2.java
AutoNumberFactory.java AutoNumberHome.java
package.html
Log:
o Moved this stuff over to varia. Does anyone styill use it?
o Changed to use Logging instead of printStackTrace, but didn't
even attempt to change the mass of try/catch blocks.
o Does not appear to be used anywhere, or be turned into a deployable
I assume this is just an application support component.
