[java ee programming] Re: JSTL/EL Exception thrown by a Vector's size attribute

[Victor]

Think twice: does your List have a "getSize()" method? NO. Therefore you
can't evaluate size with "...telephones.size".

Use this instead: "${! empty branch.telephones}".

PS
Use List implementations (e.g. ArrayList) instead of Vector.

Here's the JSTL treasure chest (just ignore the SQL part):
