Hi,
I use JPA(Hibernate implmentation).
I use Hibernate Annotations 3.4.0,Hibernate Commons Annotations 3.1.0.GA,Hibernate EntityManager 3.4.0.GA,Hibernate3(hibernate-core) (3.3.0 SP1)
I have a class News.java that has @Lob property ,and i want to load lazy this property.My property is something like this :
Code:
@Lob
@Basic(fetch = FetchType.LAZY)
public String getTitle() {
return title;
}
If i use the following Ant task to instrument property to lazy load
Code:
<project name="Samples" default="testAll" basedir=".">
<property name="librarydir" value="${basedir}/lib"/>
<path id="libraries">
<fileset dir="${librarydir}">
<include name="*.jar"/>
</fileset>
</path>
<target name="instrument">
<taskdef name="instrument"
classname="org.hibernate.tool.instrument.cglib.InstrumentTask"
classpathref="libraries"/>
<instrument verbose="true">
<fileset dir="${basedir}">
<include name="News.class"/>
</fileset>
</instrument>
</target>
</project>
And then deploy apps i got the following exception:
Code:
Caused by: org.hibernate.MappingException: Could not determine type for: org.hibernate.repackage.cglib.transform.impl.InterceptFieldCallback, at
table: News, for columns: [org.hibernate.mapping.Column(interceptFieldCallback)]
