    Could not determine type for: java.util.Collection

      hi!

      i want to use @OneToMany annotations but i get the following error after deploying my .ear file:
      "Could not determine type for: java.util.Collection, for columns: [org.hibernate.mapping.Column(omOkopf)]"

      my relations look like this:
      PvStamp(1)<->(*)OmOcros(*)<->(1)OmOkopf(1)<->(*)OmOpos

      the sql joins for the relations are:
      PvStamp.ident = OmOcros.cross_1
      OmOkopf.objekt = OmOcros.objekt
      OmOkopf.objekt = OmOpos.objekt

      PvStamp.java looks like this:

      @Entity
@Table (name="PV_STAMP")
public class PvStamp implements Serializable {
 // ... some properties
 private Collection<OmOcros> omOcros = new HashSet();
 @Id
 @Column (name = "IDENT")
 public Integer getIdent() {
 return ident;
 }
 public void setIdent(Integer ident) {
 this.ident = ident;
 }

 @OneToMany (targetEntity=ams.ingres.model.OmOcros.class, cascade=CascadeType.ALL,
 mappedBy="pvStamp")
 public Collection<OmOcros> getOmOcros() {
 return omOcros;
 }
 public void setOmOcros(Collection<OmOcros> omOcros) {
 this.omOcros = omOcros;
 }

}

      OmOcross.java 
      @Entity
@Table (name="OM_OKOPF")

public class OmOcros {
 // some properties
 private Collection<OmOkopf> omOkopf = new HashSet();
 private Collection<PvStamp> pvStamp = new HashSet();

 @Id
 @Column (name="OBJEKT")
 public int getObjekt() {
 return objekt;
 }
 public void setObjekt(int objekt) {
 this.objekt = objekt;
 }
// ... some setters/getters
 public Collection<OmOkopf> getOmOkopf() {
 return omOkopf;
 }
 public void setOmOkopf(Collection<OmOkopf> omOkopf) {
 this.omOkopf = omOkopf;
 }

 public Collection<PvStamp> getPvStamp() {
 return pvStamp;
 }
 public void setPvStamp(Collection<PvStamp> pvStamp) {
 this.pvStamp = pvStamp;
 }
}

      OmOkopf.java 
      @Entity
@Table (name="OM_OKOPF")

public class OmOkopf {
// ... some properties
 private Collection<OmOpos> omOpos = new HashSet();
 private Collection<OmOcros> omOcros = new HashSet();

 @Id
 @Column (name="OBJEKT")
 public int getObjekt() {
 return objekt;
 }
 public void setObjekt(int objekt) {
 this.objekt = objekt;
 }

// ... some setters/getters

 @OneToMany(targetEntity=ams.ingres.model.OmOpos.class, cascade=CascadeType.ALL,
 mappedBy="omOkopf")
 @JoinColumn(name="objekt")
 public Collection<OmOpos> getOmOpos() {
 return omOpos;
 }

 public void setOmOpos(Collection<OmOpos> omOpos) {
 this.omOpos = omOpos;
 }

 @OneToMany(targetEntity=ams.ingres.model.OmOcros.class, cascade=CascadeType.ALL,
 mappedBy="omOkopf")
 @JoinColumn(name="objekt")
 public Collection<OmOcros> getOmOcros() {
 return omOcros;
 }

 public void setOmOcros(Collection<OmOcros> omOcros) {
 this.omOcros = omOcros;
 }
}

      OmOpos.java 
      @Entity
@Table (name="OM_OKOPF")
public class OmOpos {
// ... some properties
 private Collection<OmOkopf> omOkopf = new HashSet();

 @Id
 @Column (name="IDENT")
 public int getIdent() {
 return ident;
 }
 public void setIdent(int ident) {
 this.ident = ident;
 }
// ... some setters/getters
 public Collection<OmOkopf> getOmOkopf() {
 return omOkopf;
 }
 public void setOmOkopf(Collection<OmOkopf> omOkopf) {
 this.omOkopf = omOkopf;
 }
}
