taglib - 2 Questions.

[Mufaddal Khumri <mu...@wmotion.com>]

Hi,

Am running my webapp under tomcat 4.1.18. Everything was fine till 
yesterday (always is:)).

I am facing this issue today. I wrote a new taglib 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.

1. How do I have my taglib take the updated values without having to 
recompile my jsp pages ?

Also I do not know if this is related. But when tomcat recompiles the 
PotatoList.jsp page above it shows me these lines in the log file:

2. Why does this happen and how do I resolve this?

Thanks in advance,
