hello frnd,
thanx for u r valuable guidence..
as per u r suggation i change the naming notation...
but problem again same..
when i use simple code without <composite-id> it works well..
but when i use composite id it gives exception like above...
Just tell me that what are conditions to use <composite-id>
1. is it necessory to write <key-many-to-one>?
2. is it necessory to override equals(),hashCode() and implements Serializable?
please help me..
again i give u my code that i use...
//mapping file
<class name="HibernateUtil.xmlConfig" table="zespl_gifnoc_lmx">
<composite-id>
<key-property name="countryCd" column="dc_yrtnuoc"/>
<key-property name="dtdVersion" column="noisrev_dtd"/>
<key-property name="dtdType" column="epyt_dtd"/>
<key-property name="dtdFileName" column="eman_elif_dtd"/>
</composite-id>
<property name="xlsFileName" column="eman_elif_lsx"/>
<property name="ICHFlag" column="galf_hci"/>
