Composite-id + hibernate

Question

hello frnd,
i give more about my prblm....
this is code that i fetch record...(main)
xml_config xConfig = new xml_config();
Criteria cri = session.createCriteria(xml_config.class);
String s="CA";
//Query q = session.createQuery("from xml_config config where config.country_cd='CA'");
cri.add(Restrictions.like("country_cd", s));
cri.add(Restrictions.like("Dtd_version", "1.0"));
List q = cri.list();//error line by eclipse ide
Iterator itr = q.iterator();
ArrayList<String> v = new ArrayList<String>();
while(itr.hasNext())
xConfig = (zespl_xml_config)itr.next();
v.add(xConfig.getDtd_FileName());
System.out.println("ICH FLAG "+xConfig.getICHFlag());
System.out.println("Dtd file Name "+xConfig.getDtd_FileName());
and this my mapping file
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="HibernateUtil.zespl_xml_config" table="zespl_gifnoc_lmx">
<composite-id>
<key-property name="country_cd" column="dc_yrtnuoc"/>
<key-property name="Dtd_type" column="epyt_dtd"/>
<key-property name="Dtd_version" column="noisrev_dtd"/>
<key-property name="Dtd_FileName" column="eman_elif_dtd"/>
</composite-id>
<property name="ICHFlag" column="galf_hci"/>
<property name="xls_FileName" column="eman_elif_lsx"/>
</class>
</hibernate-mapping>
and the output errror is ......
Hibernate: select this_.dc_yrtnuoc as dc1_0_, this_.epyt_dtd as epyt2_0_, this_.noisrev_dtd as noisrev3_0_, this_.eman_elif_dtd as eman4_0_, this_.dc_yrtnuoc as dc1_1_0_, this_.epyt_dtd as epyt2_1_0_, this_.noisrev_dtd as noisrev3_1_0_, this_.eman_elif_dtd as eman4_1_0_, this_.galf_hci as galf5_1_0_, this_.eman_elif_lsx as eman6_1_0_ from zespl_gifnoc_lmx this_ where this_.dc_yrtnuoc like ? and this_.noisrev_dtd like ?

thanx forIf you can't be bothered to spell out words like "thanks" and "please" I don't see why I should spell out answers for you.
but after changing code To what? I AM NOT PSYCHIC.
problem remains same...If you have the same problem, you have the same bug. Your code is wrong in the same way. Perhaps you didn't compile the new code? I don't know.
If you have a different problem, you have a different bug. I haven't seen your code, and you haven't described the problem or pasted the error messages. I have no idea what the problem is.
please tell what r conditions to use <composite-id>The fields have to collectively form a primary key. That's the only condition.
i have only one table with four primary keys noFour primary key fields. It's impossible to have multiple primary keys in a table.
pls help me and give proper solution to solve my
problem."That didn't work, I did something, fix it?" I'm becoming disinclined to help someone who's being quite this unhelpful.
And what is with the naming convention? What on earth posessed you to do that?
D. (quite cranky today).
