Its probably the java compiler. If your constant is declared final, the 
compiler may be performing an optimization and taking the value insteadof a 
run-time reference. You can get around this by not using a constant and using 
a get method.

Hi,

Am running my webapp under tomcat 4.1.18. Everything was fine till  
yesterday. I am facing this issue today. I wrote a new taglib -  
nextPrevLink for a jsp page called PotatoList.jsp.

<cw:nextPrevLink listSize='<%= getTotalNumberOfPotatoes()%>'
                         offset='<%=offset%>'
                         
displaySize='<%=Constants.POTATO_LIST_DISPLAY_SIZE%>'
                         link='someLink'/>

Now when i change the value of the Constants.POTATO_LIST_DISPLAY_SIZE  
in the Constants.java and "reload" my webapp thru the tomcat manager  
and go to PotatoList.jsp the taglib takes the old value of displaySize  
(I have a system.out.println("") .. inside the class that implements  
the taglib).

Now if i change the PotatoList.jsp and "save it again" ... tomcat  
recompiles PotatoList.jsp when it comes across it. This time the taglib  
nextPrevLink takes the correct new value of Constants.  
POTATO_LIST_DISPLAY_SIZE.
