Re: Emergent, please help ???

Are you sure getConceptBeans() returns an array of ConceptBean?

Re: Emergent, please help ???

i don't do jsp programming.. but if it is close to java look at this line:

for (int i=0; i < concepts.length; i++) {
concept = concepts;

is concept an array of some item or a singular item? concepts is an array as you have it.
