Hi,
i have a cmp bean "Minfo" and get my results in my client this way:
code:
try {
Collection c = getHome().findByDisk(disk);
Iterator iterator = c.iterator();
Minfo info = null;
while (iterator.hasNext()){
Object obj = iterator.next();
if (obj instanceof Minfo) info = (Minfo)obj;
System.out.println(info.getDisk()+" "+
info.getExtension());
}
} catch (RemoteException e1) {
e1.printStackTrace();
Every time i call a get-function, JBoss make a database query like this:
Executing SQL: SELECT filename, extension, disk, size, id3title, id3artist, id3length,
id3bitrate FROM minfo WHERE (id=?)
is it possible to get the information for all get-functions with one sql-call for each
bean? is it possible to configure my bean or jboss for this behavior? if the finder
has a result, is it possible to load all the bean data? or is there a other way i can
improve performance?
i have a performance problem if i call a lot of get-Methods.
Thanks a lot and sorry for my bad english.
P.S.I don't have the Admin and Dev book
