+ * Revision 1.20 2002/07/21 22:32:25 mh
+ * on insert, the "webdb_lastchange" field should get a value
+ *
+ * Revision 1.19 2002/06/29 15:44:46 mh
+ * make the webdb_create update be called webdb_create_update. it breaks things otherwise. a fixme case I know..
+ *
+ * Revision 1.18 2002/06/28 20:42:13 mh
+ * added necessary bits in templates and Database.java to make webdb_create modifiable. make the conversion from sql/Timestamp to String more robust
