********************************************
net.sf.hibernate.QueryException: could not resolve property type: userId [SELECT

groupHBM FROM com.liferay.portal.ejb.UserHBM userHBM JOIN userHBM.groups AS groupHBM

WHERE userHBM.userId = ? AND userHBM.portalId = ? ORDER BY name ASC]

Tables used as following

group_
fields
*****
1) groupId
2) portalId

users_groups(Mapping table for user and group)
fields
*****

2)userId
3) portalId


This is mapping file for table TCPS_User_
*****************************************************************************
<class name="com.liferay.portal.ejb.UserHBM" table="TCPS_User_">
<composite-id name="primaryKey" class="com.liferay.portal.ejb.UserPK">

<key-property name="portalId" type="java.lang.String"/>
</composite-id>
<!--<id name="userId" type="java.lang.String"> --><set name="groups" table="Users_Groups" lazy="true">

<key>
<column name="userId" />
<column name="portalId"/>
</key>
<!-- <key column="userId" /> -->

<many-to-many class="com.liferay.portal.ejb.GroupHBM" column="groupId" />
</set></class>
**************************************************************************************
This is mapping file for table TCPS_Group_
*************************************************************************************

<class name="com.liferay.portal.ejb.GroupHBM" table="TCPS_Group_">

<id name="groupId" type="java.lang.String">
<generator class="assigned" />
</id>
<key column="groupId" />

<set name="users" table="Users_Groups" lazy="true">
<key column="groupId" />

<column name="userId"/>
<column name="portalId"/>
</many-to-many>
<!-- <many-to-many class="com.liferay.portal.ejb.UserHBM" column="userId" /> -->
</set> </class>

Here the commented lines as well as in italic with bold format in the mapping files are previously in the working condition.
The uncommented lines with boldare changed by us for composite key.

But the exceptiontion occur in the following line
Line 1: String pk1 = userPK.userId;
Line 2: String pk2 = userPK.portalId;
Line 3: Query q = session.createQuery(query.toString());
Line 4: q.setString(0, pk1);
Line 5: q.setString(1, pk2);
Line 6: Iterator itr = q.list().iterator();
// Before modification
// userHBM = (UserHBM)session.load(UserHBM.class, pk);

where userPk is UserPK type
pk is the String type
in the line6, the excetion occur

previously we r having userId alone and passing into the session.load method. Now we r passing UserPK class into the session.load method

why that excetion occur what wrong put in my work
the exception is like that
"could not resolve protperty type:userId"
plz give ur response immedidetly.

You seem to be confused about what kind of relationship we have here. Don't try to order other people around, or you will be banned from the forum without any further warning,
