First of all I'd like to say hello everyone, since I'm new to the
group. Now to the "meat".

I'm a newcommer to the velocity templating system and I'm having some
trouble. I've setup Tomcat 5.5.2 and compiled Velocity 1.5 beta 2 and
VelocityTools 1.2. I've created a servlet that extends
VelocityViewServlet:

public class index extends VelocityViewServlet
{

 public Template handleRequest(HttpServletRequest request,
HttpServletResponse response, Context context)
 throws ParseErrorException, ResourceNotFoundException
 {
 Template tpl = null;
 context.put("name","Xabi");
 try
 {
 tpl = super.getTemplate ("test.vm");

 StringWriter writer = new StringWriter();
 tpl.merge (context,writer);
 }
 catch (ResourceNotFoundException rnfd)
 {
 System.out.println ("Error: No se encontr=F3 la
plantilla");
 rnfd.printStackTrace (System.out);
 }
 catch (ParseErrorException perrex)
 {
 System.out.println ("Error: Fallo parseando la
plantilla");
 perrex.printStackTrace (System.out);
 }
 catch (Exception ex){}
 return tpl;
 }

I've also added the corresponding servlet mappings in my web.xml:

<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

 <servlet-class>index</servlet-class>
 <init-param>
 <param-name>properties</param-name>
 <param-value>/WEB-INF/velocity.properties</param-value>
 </init-param>

 <servlet>

 <param-value>/WEB-INF/velocity.properties</param-value>
 </init-param>

 <servlet-mapping>

 <url-pattern>/</url-pattern>
 </servlet-mapping>
 <servlet-mapping>
 <servlet-name>velocity</servlet-name>
 <url-pattern>*.vm</url-pattern>
 </servlet-mapping>
 <session-config>
 <session-timeout>
 30
 </session-timeout>
 </session-config>
</web-app>

And also created a velocity.properties file in
/WEB-INF/velocity.properties:

resource.loader = webapp
webapp.resource.loader.class =
org.apache.velocity.tools.view.servlet.WebappLoader
webapp.resource.loader.path=/templates
webapp.resource.loader.cache = true
runtime.log=/WEB-INF/logs/velocity.log
input.encoding=UTF-8
output.encoding=UTF-8

And created a very simple template called test.vm in
/MyAppRoot/templates/test.vm:

<?xhtml version="1.0" encoding="UTF-8"?>
<html>
 <head>
 <title>Test</title>
 </head>
 <body>
 THIS IS A TEST:
 Hello $name
 </body>
</html>

But whenever I go to http://localhost:8080/myapp , I only get a blank
page.
Digging into Tomcat logs, I've found this:

Witch for me indicates that the templates path I setup in
resource.loader is readed correctly but for some reason I don't know
whenever I return the template, it's searched in the AppRoot folder.

Does anybody have an idea on how to fix this?

P.S: Sorry about the long post, but I thought giving more information
would be better.
