[LazyInitializationException] could not initialize proxy - t
Hi all,
I'm getting the above error while trying to show entities with lazy-loaded properties.
I have a SLSB in which I retrieve an Entity from the Database.
The EntityBean is as follow:
public class Walzen implements java.io.Serializable {
.
.
.
private Werkstoffe werkstoffe;
.
.
.
@ManyToOne(cascade={},
fetch=FetchType.LAZY)
@JoinColumn(name="WERKSTOFF", unique=false, nullable=false, insertable=true, updatable=true)
public Werkstoffe getWerkstoffe() {
return this.werkstoffe;
}
.
.
.
}
where Werkstoffe is also an EntityBean:
@Entity
@Table(name="WERKSTOFFE"
, uniqueConstraints = { }
)
public class Werkstoffe implements java.io.Serializable {
.
.
.
@Column(name="NAME", unique=false, nullable=false, insertable=true, updatable=true)
public String getName() {
return this.name;
}
.
.
.
}
In my SessionBean I do a simple "select w from Walzen" in a @Factory-Method.
As I try to show the name-Attribute in the JSP like:
<f:view>
<t:dataTable id="walzen" var="walze" value="#{walzenliste}">
<t:column>
<h:outputLabel value="#{walze.hydronummer}">
</h:outputLabel>
</t:column>
<t:column>
<h:outputLabel value="#{walze.werkstoffe.name}">
</h:outputLabel>
</t:column>
</t:dataTable>
</f:view>
I get the above Error.

Where am I wrong? Do I have to set the fetchtype to EAGER? But for what is LAZY then? Shouldn't Seam/JSF know when to load the Data from the Werkstoffe-Table?
Thanks for any help!
Stefan
