In your second XML example, are you still using the same method signature?
Like this:
List<Send> getAllItems(@Param("offset") int offset, @Param("limit") int
limit);
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN" "
http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd";>
<mapper namespace="cz.apache.ibatis.SendMapper">
<select id="getAllItemsX" parameterType="map"
resultType="cz.apache.ibatis.Send" >
select * from send LIMIT #{offset}, #{limit}
</select>
</mapper>
