Found the problem and solution.

The setter method in my code was accepting ArrayList, so it was throwing
the  java.lang.IllegalArgumentException: argument type mismatch.

But the Ibatis was returning List object.

Why Ibatis can not convert from List to ArrayList. ?????????????

Subject: Very Urgent-Badly need you people Help

Can any one please spend some time for this. I have to deliver the code

I am doing lazy loading. I am doing basically N+1 loading. I have two
tables which has 1:N relationship.
If the table have the data with 1:1 ratio then my query is working fine.

But if any of master is having more than one detail record then it is
throwing the following error.
--- Check the result mapping for the 'properties' property. 

--- Cause: java.sql.SQLException: Error: executeQueryForObject returned
too many results.

Here i am giving the my mapping file.

<resultMap id="userMapOne" class="user">

<result property="userid" column="USR_ID"/>

<result property="role" column="ROLE_ID"/>

<result property="description" column="DESCRIPTION"/>

<result property="properties" column="USR_ID" select="select2" />


( I have set method for properties attribute and this accepts object of
type property)

<resultMap id="userMapTwo" class="property">

<result property="userid" column="USR_ID"/>

<result property="propertyname" column="PROPERTY_NAME"/>

<result property="propertyvalue" column="PROPERTY_VALUE"/>


<statement id="RamBabu" resultMap="userMapOne">

     select * from USR_BASIC_INFO


<statement id="select2" resultMap="userMapTwo">

   select * from USR_EXTENSION_INFO where USR_ID=#userid#
