Hi Otmar
I'm not certain but stuff inside the ${...} is already assumed to be variable
names. What
is the type of 'myCollection', is actually a collection? I would assume it is
some sort of
array and then you can use:
<bean:size id="myId" collection="${myCollection[index].myProperty}"/>
Else you should be iterating through the collection to identify individual
objects. Give
us a bit more detail on the JSP and we might be able to help.
If you variables are called 'myCollection1' and 'myCollection2' and you are
trying to
reference them in a loop I'm not sure you will have much success. You would
need
some type of eval() function to be able to interpret strings as variable names.
I don't
know if this can be done - however it's probably not the best practice. Better
to
structure the data into a collection of objects.
Cheers
