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).

I've got the Velocity 1.5 engine integrated into my application's code and
everything seemed to be going great.  But then, I noticed that template
caching is only _kinda_ working.

I've stepped through the Velocity source code to verify that my template
object is correctly reloading when modified (I'm using
FileResourceLoader).
By verify, I mean that I can see that the ResourceLoader's isCachingOn()
is
correctly returning true and the class's modificationCheckInterval
reflects
my property setting (10 seconds).  And if I...

- call Velocity.getTemplate(String name)
- run a merge( Context context, Writer writer) on the returned template
- go out to the file system and edit the template file (after waiting 10
seconds)
- and then re-run the Velocity.getTemplate()

...I see that the Template object I get from getTemplate() the second
time,
reflects the file system change I made (Yeah!), because its data property
is
holding my new stuff.  BUT, when I call merge on it, the StringWriter I
get
back reflects the old state of the template, before my change!

Here's my code:

public static String buildView(String templateName, Map templateData )
throws Exception {
    VelocityContext velocityContext = new VelocityContext(templateData);
    Template velocityTemplate = Velocity.getTemplate(templateName);
    StringWriter stringWriter = new StringWriter();
    velocityTemplate.merge( velocityContext, stringWriter );
    return stringWriter.toString();
}

What am I missing?  I went back to Velocity 1.4 to make sure it wasn't
some
new bug in 1.5, but 1.4 behaves the same way.

Thanks for any help,

Jeff
