maybe you have multiple copies of the jar file as you suggest?
I've had problems before (with other libraries) with things working when at
a break point but not while running continuously. it turned out that one
classpath was active at the break and a different one while running.
be interesting to do a print/log statement while running to see if you have
the same results (rather than breaking and manually checking).

Will,
Thank you for taking the time to put together the sample project. I've
run
that in my environment, and as you say, it runs as expected!
Per your initial questions, I have not changed the max size of the cache.
I am running in a web app, but I'm confident it's not a caching issue on
the
browser. I'm stepping through the source code, including velocity source
code, in the Eclipse debugger on Tomcat 5.5.
After an edit to my template, the Modified Date shown in Windows Explorer
is
updating. If I set a breakpoint in the isSourceModified() method of
Velocity's FileResourceLoader, it properly returns true after an edit to
the
template. And then at another breakpoint in the merge() method of
Template,
I look at a toString() on the "data" property of the Template class, and
it
shows the new, edited template content. But within that merge() method,
the
line that reads:
( (SimpleNode) data ).render( ica, writer);
seems to result in a writer that holds an old version of the template,
ignoring the new stuff in the "data" property of the Template.
I get a little lost trying to step through that render() method. Can you
recommend any key things I could look at that might reveal what's
happening?
On a different note, here are the differences I noticed between your
VelocityWebTest test project and my project...
1) your template is inside the file system of your web app, mine is not
2) you're using the version of the velocity JAR with dependencies, my app
has the dependencies separate from the velocity jar
3) when I set the velocity properties before init() I specify a
"velocimacro.library" (which works fine)
But for all 3 cases I modified my app to be configured/run like yours, and
it made no difference.
I've had a co-worker look over my shoulder to make sure I'm not doing
something insanely stupid, but if I am, he's not seeing it either.
The only thing I can think of, that I've not had the time to fully explore
yet, is that one of dependency jar files in my application is at fault.
Perhaps I'm on a wrong version of one of the dependencies and it's getting
picked up, even when using the full velocity-dep-1.5.jar jar. (I have a
dependency on commons-collections, even outside of the use of Velocity).
This page:
http://velocity.apache.org/engine/devel/jar-dependencies.html
lists the dependencies but doesn't give version numbers. Are version
numbers listed somewhere that I'm missing?
Thanks for your help.
Jeff

Hi Jeff,
I built a small test servlet to check this and had no problems. I used
the
StringWriter just as you described. I displayed a file, changed it, and
refreshed the page. When I refreshed in less than 10 seconds it showed
the
old text. When I refreshed after 10 seconds, it showed the new text.
How are you changing the file? Obviously, the file timestamp has to
change
for Velocity to notice it is new.
Also - is this a web app? Are you sure it's just not something silly like
a
browser cache of the page?
(Test code attached, though it'll probably get stripped by the list serv).
