expression language

[James Clarke]

Hi all,

Do map objects need to be stored as attibutes in the request object for accessing them from expression language ?
ie. In ${testmap.name} does testmap need to be store as an attribute in a request.

is there other objects that can store the map for exp language to be able to access it ?

thanks,

J.C

James,

The answer to u'r first question

1)Do map objects need to be stored as attibutes in the request object
for accessing them from expression language ?

Actually request is one of the scopes where you can store map/bean objects. The other scopes where u can store those objects are
-> session
-> page
-> application

2)where the bean class file needs to be stored for el to access it ?

All the class files need to be stored in WEB-INF/classes directory of the web application

Hope this would answer your questions

Hi,

Correct me if Im wrong but my understanding was that beans don't need to be stored as an attribute, but is accessed automatically from the WEBINF/classes directory ???

Yes, you are right that bean is stored in classes.
But the instance of bean with user input values is stored in some scope for further manipulation.

I hope this helps.

Thanks
