Thank you Dave, I just managed to resolve the issue in a slightly
earlier post.
Here is the action that backs the JSP. Now In my table I have a column
which prints out db.localhost.test.Groups[name=ADMIN] because the object
is db.localhost.test.Groups and it has a single property called name.
Another thing to fix.
package struts2.reflection;
import com.opensymphony.xwork2.ActionSupport;
import java.util.ArrayList;
import java.util.List;
import java.util.Map;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Query;
import org.apache.commons.collections.BeanMap;
/**

public class GetPropertyNames extends ActionSupport {
List result = null;
BeanMap propertyValues = null;
private EntityManagerFactory entityManagerFactory;
public void setEntityManagerFactory(EntityManagerFactory
entityManagerFactory) {
this.entityManagerFactory = entityManagerFactory;
}
@Override
public String execute() {
EntityManager entityManager =
entityManagerFactory.createEntityManager();
Query namedQuery =
entityManager.createNamedQuery("Customers.findAll");
result = namedQuery.getResultList();
if (result != null && result.size() > 0){
propertyValues = new BeanMap( result.get(1) );
//has unwanted property "class" but there is no valid remove
method that will not throw an exception, so will take care of this in
getter
}
return SUCCESS;
}
public List getResult(){
return result;
}
public List getPropertyValues(){
//can now remove unwanted property "class"
ArrayList arrayList = new ArrayList(propertyValues.keySet());
arrayList.remove("class");
return arrayList;
}
}
