I 'm trying to make a crud in Strud2 with hibernate and I can not combine two tables. Can you help me
Table 1 is Trama

@Entity
@Table(name="trama", catalog="bd_1")

public class Trama  implements java.io.Serializable {

     private int traNoca;         //Int
     private int catNoca;       //Enlace con categoria
     private String tradat;       //Dato sin importancia

    public Trama() {}

    public Trama(int traNoca, int catNoca, String tradat)
    {this.traNoca = traNoca;  this.catNoca = catNoca;  this.tradat = tradat;  }

     @Id
    @Column(name="tra_noca", nullable=false)
     public int getTraNoca() {return this.traNoca;} ES
    public void setTraNoca(int traNoca) {this.traNoca = traNoca; }

    @Column(name="cat_noca", nullable=false)
    public int getCatNoca() {return this.catNoca;}
    public void setCatNoca(int catNoca) {this.catNoca = catNoca;}

    @Column(name="tra_dat", nullable=false, length=45)
    public String getTradat() {return this.tradat;}
    public void setTradat(String tradat) { this.tradat = tradat;  }
}


This is His mapping

<hibernate-mapping>
    <class name="entidad.Trama" table="trama" catalog="bd_1">
        <id name="TraNoca" type="int">
            <column name="tra_noca" />
           <generator class="assigned"></generator>
        </id>
        <property  name="CatNoca" type="int">
            <column name="cat_noca" />
         </property>
        <property name="Tradat" type="string">
            <column name="cat_dat" length="50" />
        </property>
    </class>
</hibernate-mapping>

Categoria is 2 Table is which is the main

package entidad;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "trama", catalog = "bd_1"   )

public class Categoria  implements java.io.Serializable {

     private int catNoca;
     private String catNom;

    public Categoria() {}

    public Categoria(int catNoca, String catNom)
    {this.catNoca = catNoca;   this.catNom = catNom;}

     @Id
     @Column(name="cat_noca", nullable=false)
    public int getCatNoca() {return this.catNoca;}
    public void setCatNoca(int catNoca) {this.catNoca = catNoca;}

    @Column(name="cat_nom", nullable=false, length=45)
    public String getCatNom() {return this.catNom;}
    public void setCatNom(String catNom) { this.catNom = catNom; }
}
This is His mapping

<hibernate-mapping>
    <class name="entidad.Categoria" table="categoria" catalog="bd_1">
        <id name="CatNoca" type="int">
            <column name="cat_noca" />
           <generator class="assigned"></generator>
        </id>
        <property name="CatNom" type="string">
            <column name="cat_nom" length="50" />
        </property>
    </class>

Strut2
Which sends the order

    public  void detalle2(String noca,T entity) {

        Session session = HibernateUtil.getSessionFactory().openSession();
        Transaction beginTransaction = session.beginTransaction();
        session.createSQLQuery("select c.CatNoca, c.CatNom, t.CatNoca, t.TraNoca, t.CatNom, t.tradat  from Trama t INNER JOIN Categoria c ON t.CatNoca="+entity);
        beginTransaction.commit();
        session.close();
    }
