Hi Chris,
There are two ways to enhance classes.
1) Build time enhancement
Here is a link for build time enhancement:
http://openjpa.apache.org/builds/latest/docs/manual/manual.html#ref_guide_pc_enhance_build
Ant task for that is
http://openjpa.apache.org/builds/latest/docs/manual/manual.html#ref_guide_integration_enhance
2) Run time enhancement.
http://openjpa.apache.org/builds/latest/docs/manual/manual.html#ref_guide_pc_enhance_runtime
If you did build time enhancement then
Decompile your class file and see if the class implements PersistenceCapable ?
If it implements PersistenceCapable that means the class is enhanced.
Regards,
Ravi.

I'm having an issue when running my application in that OpenJPA is
complaining my class has not been enhanced but the class looks fine to me,
can anyone see if I am missing something stupid please.
Here is the top of the stack trace:
<openjpa-1.2.0-r422266:683325 nonfatal user error>
org.apache.openjpa.persistence.ArgumentException: Attempt to cast instance
"com.trm.core.curre...@cf3539" to PersistenceCapable failed. Ensure that it
has been enhanced.
FailedObject: com.trm.core.curre...@cf3539
<openjpa-1.2.0-r422266:683325 nonfatal user error>
org.apache.openjpa.persistence.ArgumentException: Attempt to cast instance
"com.trm.core.curre...@cf3539" to PersistenceCapable failed. Ensure that it

FailedObject: com.trm.core.curre...@cf3539
I am wondering if is because of how I am using the objects. Basically the
code is loading some data from a file, depending on some configuration the
code will try to create the appropriate objects and then persist them. In
order to make the code abstract, the code loads the data then creates a
generic object and calls it setters to populate the data. Hence when the
EntityManager is called to persist the object it I am passing it a generic
object since I can't cast the object to the it's actual class at run time.
>From the stack trace it seems that OpenJPA knows the correct class type so I
don't understand why it is complaining.
Here is my class:
@Entity
@Table(name="currency")
public class Currency implements Serializable
{
/**
*
*/
private static final long serialVersionUID = 1L;
@Id
// @GeneratedValue(strategy=GenerationType.AUTO)
private String isocode;
private String name;
private String country;
public Currency(){
}
/**
* @param isocode the isocode to set
*/
public void setIsocode(String isocode) {
this.isocode = isocode;
}
/**
* @return the isocode
*/
public String getIsocode() {
return isocode;
}
/**
* @param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* @return the name
*/
public String getName() {
return name;
}
/**
* @param country the country to set
*/
public void setCountry(String country) {
this.country = country;
}
/**
* @return the country
*/
public String getCountry() {
return country;
}
Thanks for any advice.
Chris
