John:
This is indeed very helpful. Somehow after I reboot the NT the example is
working.
If it is of some value, I have re-written the documentation for
servlet_example2 as follows:
==================================================================================================================
Welcome to Velocity!
source: README.txt from the \velocity-X\examples\servlet_example2 directory
(where X is the version e.g. 1.3)
As always, the if you have any questions :
1) Make sure you followed any directions :) (did you build everything?
particularly ant jar, ant jar-dep, ant examples)
2) Review documentation included in this package, or online at
http://jakarta.apache.org/velocity
3) Ask on the velocity-user list. This is a great source of support
information.
To join, read http://jakarta.apache.org/site/mail.html and then follow
the
link at the bottom to join the lists.
servlet_example2
--------------------------
This is a slightly more complicated example of how Velocity can be used
with
your favorite servlet engine. To use this, you should have a basic
understanding
how your servlet engine works, and how you deploy and access servlets to
try this.
While we cannot supply this, we know of a good one :)
http://jakarta.apache.org/tomcat/
The difference is that instead of self-configuring, the servlet
SampleServlet2 will
use an external velocity.properties file specified in the web.xml
deployment
descriptor.
The example will demonstrate how to use either the FileResourceLoader to
load a
template from a subdirectory of your webapp, or the ClasspathResourceLoader
to
load a template from a jar file placed in WEB-INF/lib.
This example assumes you have played with servlet_example1 and understand
the basics.
1) Get a servlet engine. Tomcat, from the Jakarta project, is an
excellent implementation. (In fact, it's the official reference
implementation...)
2) Install said servlet engine.
Setting up to use the ClasspathResourceLoader
-----------------------------------------------------------------------
3) Build this servlet example : in build - ant examples
4) Setup a webapp under tomcat :
- make a new 'webapp' : in tomcat's webapps directory,
make a new directory structure as follows :
velexample
velexample/templates
velexample/WEB-INF
velexample/WEB-INF/lib
velexample/WEB-INF/classes
- put the velocity-X.jar and velocity-dep-X.jar (X is the version e.g.
-1.3) into the velexample/WEB-INF/lib directory
- put the SampleServlet2.class into the velexample/WEB-INF/classes
directory
- put the templates.jar (generated after the ant build) into the
velexample/WEB-INF/lib directory.
- put the web.xml into the velexample/WEB-INF directory
- place a copy of velocity.properties.classloader, but rename to be
velocity.properties into velexample/
- at this point, you should be able to restart tomcat and access the
servlet.
- so bounce tomcat, go into your web brower and go to :
http://<your computer's ip
address>:8080/velexample/servlet/SampleServlet2
- you should see the sample output.
- if you get a 404, page not found, try editing /tomcat/conf/web.xml and
remove the comments around
<!-- The mapping for the invoker servlet -->
<servlet-mapping>
<servlet-name>invoker</servlet-name>
<url-pattern>/servlet/*</url-pattern>
</servlet-mapping>
At this point, you are accessing the template via the
ClasspathResourceLoader. Note also
that the velocity.log will be placed in the velexample directory. (root of
your webapp.)

- put the sample.vm into the velexample/templates directory.
- put the web.xml into the velexample/WEB-INF directory

velocity.properties

I had the same problems as you, I'm still a newbie myself but the attached
link helped me a lot, hope it would help you too.

Subject: [velocity - newbie] servlet_example2 blank page
I am brand new to this list and to velocity. I installed velocity and
wanted to try the servlet examples to make sure my installation was
working. I found a couple of problems with the instructions:
1) rename volocity.properties.classloader to velocity.properties must be
copied to the .../velexample subdirectory (no stated where it goes).
2) I had to uncomment in /tomcat/conf/web.xml the section containing:
>invoker< ... >/servlet/*< (I was getting a 404 page not found)
3) there is no such thing as "volocity-1.1-rc1.jar", I could only find the
"velocity-1.3.jar"
4) the place to go in the browser is
http://127.0.0.1:8080/velexample/servlet/SampleServlet2 (notice the 2 at
the end, I was getting a 404 again)
However, I still get a blank page and no signs of the "velocity.log" that I
was suppose to find (searched the entired /tomcat/ directory).
I beg you all to be gentle and focus on the issue. How do we get newcomers
up and running so the velocity experience feels great right from the
beginning.
