Static ints being cached 2004-01-08 - By Allistair Crossley
Back
Hi All,
I have an interface containing public final static ints. My servlets reference
these ints when making database inserts. Yesterday I reordered the values of
the ints and noticed that old values were still being placed into the database.
I guess this was somehow a caching problem. I deleted the .class from Tomcat to
ensure a recompile would place a new .class and restarted Tomcat, but old
values still went in the database!
- If I output the static ints from a JSP the new values come out.
- If I output the static ints from a class the old values come out.
- If I force the class using the interface to recompile, then the class starts
using the new values
It seems that somehow references are being stored by Tomcat somewhere since a
restart does not work but I don't know much about this. I would like to trust
that when I change values that Tomcat is able to pick these up, at the very
least on a restart!! I don't want to go through recompiling my whole app.
I am using Ant in a multi-developer environment to compile and it compiles only
classes that have changed. I cannot recompile the whole app everytime I change
constant values.
Help and understanding appreciated ...
Cheers, ADC
