Hi All,
I have some doubts about the performance of CMP and CMR in EJB2 AND
JBOSS3.
Scenario is like this:
I have 1 bean called EMPLOYEE. It has got 1:N relationship with GROUPS
bean. This relationship is defined thru CMR.
I have a method on EMPLOYEE :
Public GroupModel[] getGroupModels()
{
// get all the groups
Collection groups = this.getGroups();
GroupModel[] arr= new GroupModel[groups.size()];
Iterator itr = groups.iterator();
Int i=0;
while(itr.hasNext())
{
Group g = (Group)itr.next();
arr[i] = g.getModel();
i++;
}
return arr;
}
So, First container will get the collection of EJBObjects for Group
bean. Then, it will start loading the beans one by one.
QUESTION is if the no. of records is high (100s) then will it not be
slow? If yes then is it better to go for Direct JBDC Calls instead of
using Beans for this purpose?
PLEASE HELP
Any real life experience is more than welcome.
Thanks,
Saroj
