<?xml version='1.0' encoding='utf-8'?> <!doctype hibernate-mapping public     "-//hibernate/hibernate mapping dtd 3.0//en"     "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping>      <class name="com.usersentity" table="users" schema="" catalog="protein_tracker">         <id name="id">             <column name="id" sql-type="int" not-null="true"/>         </id>         <property name="name">             <column name="name" sql-type="varchar" length="45" not-null="true"/>         </property>         <property name="total">             <column name="total" sql-type="int" not-null="true"/>         </property>         <property name="goal">             <column name="goal" sql-type="int" not-null="true"/>         </property>         <set name="userhistoriesbyid" inverse="true">             <key>                 <column name="id_user" not-null="true"/>             </key>             <one-to-many not-found="ignore" class="com.userhistoryentity"/>         </set>     </class> </hibernate-mapping>

userhistory:

<?xml version='1.0' encoding='utf-8'?> <!doctype hibernate-mapping public     "-//hibernate/hibernate mapping dtd 3.0//en"     "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping>      <class name="com.userhistoryentity" table="user_history" schema="" catalog="protein_tracker">         <id name="id">             <column name="id" sql-type="int" not-null="true"/>         </id>         <property name="entrydate">             <column name="entry_date" sql-type="datetime" not-null="true"/>         </property>         <property name="entry">             <column name="entry" sql-type="varchar" length="45" not-null="true"/>         </property>         <property name="iduser">             <column name="id_user" sql-type="int" not-null="true"/>         </property>         <many-to-one name="usersbyiduser" class="com.usersentity">             <column name="id_user" not-null="true"/>         </many-to-one>     </class> </hibernate-mapping>

how can fix issue?

mark many-to-one mapping usersbyiduser insertable = false , updatable = false. allows relationship managed single property, iduser have mapped.
