I am using jboss3.2.3 with sql 2000. I have one SessionBean and two EntityBean. They
work fine, but have a small question! I have a jsp to execute finder method, as
following:
Collection c2 = eCardAdminLocal.getAllECard2("type1", "name9");
if (c!=null) {
Iterator iterator2 = c2.iterator();
while (iterator2.hasNext())
{
ECardLocal eCardLocal2 = (ECardLocal) iterator2.next();
out.println(eCardLocal2.getSenderEmail());
out.println(eCardLocal2.getSenderName());
out.println(eCardLocal2.getMessage());
out.println(eCardLocal2.getECardTemplate());
}
}
getSenderEmail(), getSenderName(), getMessage() are correct, but getECardTemplate()
return null!!
jsp file display's message as following:
email9 name9 message9 null
who can tell me Why!
Thanks!!
my configuration and java files:
ECardLocal.java
public interface ECardLocal extends javax.ejb.EJBLocalObject {
public void setECardTemplate(ECardTemplateLocal eCardTemplate);
public ECardTemplateLocal getECardTemplate();
}
ECardBean.java
abstract public class ECardBean implements EntityBean {
public abstract void setECardTemplate(ECardTemplateLocal eCardTemplate);
public abstract ECardTemplateLocal getECardTemplate();
}
ECardTemplateLocal.java
public interface ECardTemplateLocal extends javax.ejb.EJBLocalObject {
public void setECards(Collection eCard);
public Collection getECards();
}
ECardTemplateBean.java
abstract public class ECardTemplateBean implements EntityBean {
public abstract void setECards(Collection eCard);
public abstract Collection getECards();
}
