Ah, ok, now it is clear. This has nothing to do with XDoclet at all, rather the conversion that you specified, is wrong because it converts between boolean/java.lang.Boolean and int/java.lang.Integer. The problem arises because the JDBC driver returns a java.lang.Byte object for the TINYINT column and not an java.lang.Integer object that the conversion expects. Therefore you'll have to either use BIT as the JDBC column type or write your own Boolean2Byte conversion (simply copy the code of the Boolean2Int conversion and replace Integer with Byte).
