I’ve got this problem that It always hit the PropertyAccessException when trying to saveOrUpdate(); I’m using Spring 3 and hibernate 3.6 with tomcat 7.
I’ve got a M-M Akte to Pemilik
Here is the code: (Simple properties are omitted for the sake of brevity)
public class Akte implements Serializable, Comparable {
private Long id;
private int version;
AutoPopulatingList pemiliks;
public Akte() {
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public int getVersion() {
return version;
}
public void setVersion(int version) {
this.version = version;
}
public AutoPopulatingList getPemiliks() {
return pemiliks;
}
public void setPemiliks(AutoPopulatingList pemiliks) {
this.pemiliks = pemiliks;
}
}
public class Pemilik implements Serializable {
private Long id;
private int version;
private Set aktes = new HashSet();
public Pemilik() {}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public int getVersion() {
return version;
}
public void setVersion(int version) {
this.version = version;
}
public Set getAktes() {
return aktes;
}
public void setAktes(Set aktes) {
this.aktes = aktes;
}
}
here are the mapping files
<hibernate-mapping package="com.notaris.beans">
<class name="Akte" table="AKTE" dynamic-insert="true" dynamic-update="true" lazy="true">
<id name="id" column="AKTE_ID">
<generator class="native"/>
</id>
<version name="version" column="VERSION"/>
<bag name="pemiliks" table="AKTE_PEMILIK" lazy="true" cascade="save-update">
<key column="AKTE_ID"/>
<many-to-many class="Pemilik" column="PEMILIK_ID"/>
</bag>
</class>
</hibernate-mapping>
<hibernate-mapping package="com.notaris.beans">
<class name="Pemilik" table="PEMILIK" lazy="true">
<id name="id" column="PEMILIK_ID">
<generator class="native"/>
</id>
<version name="version" column="VERSION"/>
<set name="aktes" table="AKTE_PEMILIK" lazy="true" inverse="true" cascade="save-update">
<key column="PEMILIK_ID"/>
<many-to-many class="Akte" column="AKTE_ID"/>
</set>
</class>
</hibernate-mapping>
now i was trying to save it during processFinish()
by doing something like:
akteService.createAkte(cmd.getAkte());
Inside the Akte there is a AutoPopulatingList that contained Pemilik object.
and AutoPopulatingList is initiated the simple way new AutoPopulatingList(Pemilik.class);
and here is the stack trace

Any ideas guys?
I’ve taken a look at the pemiliks property, it’s just a simple AutoPopulatingList, I dont
understand what’s the issue with the setter not able to access it?
Thank you.
The type of a collection that needs to be managed by hibernate should be a java.util.Set or List. The error is most likely due to pemiliks being of type AutoPopulatingList, change it to a List (also the setter & getter). You can initialize the collection to an instance of AutoPopulatingList.
