Q: How to recompile a JSP page if its include file has been changed?
Hi:
I have a couple of include files (of format <%@ include file=file.jsp %>) inside of all
my jsp files for site generic layout. When a designer makes a change to a navBar.jsp
include file, for example, what we do right now is restart Tomcat to see the changes.
Is there another way to force a JSP page to recompile besides restarting Tomcat
altogether?
Thank you.

1. Yes... delete the pre-compiled servlet for that JSP.
2. Yes... delete all pre-compiles servlets for your webapp.
You'll find these, by default, in $CATALINA_HOME/work

1. No.
2. No.
You must update the timestamp, either via touch or via some manual method.
I suppose you could write a shell/batch script to do this for you based on
your specific criteria. This is an optimization based in the Servlet and
JSP specifications themselves. It asks the timestamp question because it's
a quick "sanity check" -- do I really need to recompile this? It is
specified behavior that the container ***not*** recompile "unchanged" jsp's,
and by "unchanged" I mean the timestamp is not newer than the timestamp that
existed at the previous compile-time.
Is this clear as mud ? ;)
Oh and tomcat WILL NOT check the timestamp on include files.
Hope this helps.

When a JSP page gets its timestamp changed Tomcat automatically reloads it. Is there a
way to force Tomcat to do that on a non-changed file? On all JSP files?

Thank you, this is helpful.
Any suggestions for automatic reload, while Tomcat is running?
We use Tomcat 4.0. Thanks

on unix / linux you use "touch"
jsp's compiling is based on their timestamp. "Was this file modified after
I last compiled it?" It does not take into account the include file's
timestamp.
i have a command that works on unix to update the times on all your jsps.
Go into your /webapps directory and type
find . -name "*.jsp" -exec touch '{}' \;
or just go to the individual file and type:
touch MyJsp.jsp
on dos/windows just open the file in notepad, put in or erase a space or
return, and then save it.

If you are on a unix system, you can just touch the file. It should then recompile the jsp.
Note, you would have to touch every file that used the included file.
