Re: Clean way to obtain a property's value...

[Axel Gross]

some ideas
- get a singleton instance of GargantusLists and call it 'ns' (for
namespace) then you just have to use
ns.ESURVEY_RESULT_DISPLAY_TYPE_LIST
- make a stupid tld in which you define those constants
- use jakarta jexl or another expression language which allows more than jsp2.0 EL

Re: Struts usage question

[Axel Gross]

hi there!

the el libs use the jsp 2.0 expression language (${} instead of <%= %> )
If you don't have a servlet container which supports that by itself, you can
use the el-tags to use it at least inside of the struts tags.
