Switching to VVS
I am trying to switch to using the VVS and now I can't located my
template files.
Other than extending VVS instead of VS, I only made one change. I
changed from
file.resource.loader.path
to
webapp.resource.loader.path
in my velocity.properties file. And here is my test servlet mapping in
my web.xml
<servlet>
<servlet-name>index</servlet-name>
<servlet-class>com.test.IndexServlet</servlet-class>
<init-param>
<param-name>org.apache.velocity.properties</param-name>
<param-value>/WEB-INF/velocity.properties</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>index</servlet-name>
<url-pattern>/index</url-pattern>
</servlet-mapping>
Nothing else changed. VS works. VVS doesn't. It tells me it can't
find my index.htm which is my template file. Is there something else I
need to change.
Also, I had to find out about the change to the velocity.properties file
in the mailing list archives. Can anyone point me to a link of all the
CURRENT available property options?
Thanks.

well, it's in the WebappLoader javadocs, but i'm not sure we mention it
elsewhere. more/better documentation could never hurt.

here's the problem. the webapp loader is not the file resource loader. it
uses the webapp as it's root, not the local computer's file system. this
makes VelocityView apps much easier to move around and lets us package them in
WARs and other cool things like that.
try
webapp.resource.loader.path=/WEB-INF/templates

Ok, let's start kind of fresh. I decided to do this the "suggested"
way, so here is what I am doing. My servlets simply extend HttpServlet
now. Nothing fancy. Now I will show you my files.
web.xml
<servlet>
<servlet-name>velocity</servlet-name>
<servlet-class>org.apache.velocity.tools.view.servlet.VelocityViewServlet</servlet-class>
<init-param>
<param-name>org.apache.velocity.properties</param-name>
<param-value>/WEB-INF/velocity.properties</param-value>
</init-param>
<load-on-startup>10</load-on-startup>
</servlet>
<servlet>
<servlet-name>index</servlet-name>
<servlet-class>com.test.IndexServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>velocity</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>index</servlet-name>
<url-pattern>/index</url-pattern>
</servlet-mapping>
velocity.properties
webapp.resource.loader.path =
c:/programs/tomcat/webapps/anykey/WEB-INF/templates
IndexServlet.java
public class IndexServlet extends HttpServlet
{
public void doGet(HttpServletRequest request, HttpServletResponse
response) throws IOException, ServletException
{
doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse
response) throws IOException, ServletException
{
this.getServletContext().getRequestDispatcher("/index.htm").forward(request,
response);
}
}
And I get this cool error when trying to access..
Unable to find resource '/index.htm'
org.apache.velocity.exception.ResourceNotFoundException: Unable to find resource '/index.htm'
....
....
Thanks.

what are the rest of your resource.loader properties?
in particular, are you setting
resource.loader=<some name>
try commenting out all your resource loader properties except for
webapp.resource.loader.path

what does IndexServlet do? are there VVS methods does it overrides?

why not just map *.htm or /index*? don't you need either an exact match or a
wildcard?
also, you say "it tells me it can't find..." what exactly is "it"? Tomcat?
VVS?

if you mean velocity.property options, they're pretty much the same for the
VVS as any other velocity application, with the exception that the VVS will
automatically set
resource.loader=webapp
webapp.resource.loader.class=org.apache.velocity.tools.view.servlet.WebappLoad
er
and will also manually set logging to the ServletLogger (i don't remember the
logsystem property name offhand and won't try).
these properties are set before loading your velocity.properties to allow you
to override them. so if you set resource.loader=file in your props, then it
won't register the webapp loader. you need to either not set it or else set
resource.loader=webapp,file
oh, and the VelocityLayoutServlet does have extra velocity.properties, but
those are documented.

ah. yeah, that should work for the VVS as well (assuming your resource.loader
properties are correct), but you should know that that's not the standard
practice (which is a lot easier, IMHO). :)

Re: Switching to VVS

Well, the problem is I am not mapping that to a velocity template.
index is a Servlet. The Servlet extends VVS and returns a Template on
the handleRequest. So what I did is correct for what I am trying to
do. It works fine with VS.
Thanks Mike.
