Hi NG!

I'm trying to map a byte[]-property to a DB2-database using:

- hibernate 3.2.4.sp1
- hibernateTools 3.2.0.beta9
- spring-framework-2.0.6

My smart HibernatePlusSpringTotallyEasy-book tells me just to build a class like this:

@Entity
public class Picture {
private byte[] data;

@Lob
public byte[] getData() {
return data;
}

public void setData(byte[] data) {
this.data = data;
}
}

Said and done, the hibernate-tools generate this class-mapping-xml-file:

[...]
<property name="data" type="org.hibernate.type.PrimitiveByteArrayBlobType">
<column name="data" />
</property>
[...]

If I start my Spring-Container, I get the following exception, that I do not understand.

Any help would be really appreciated...
