Hi thanks for your respsonse, Its not liable to be a permissions error as i am running tomcat on my local pc and have installed it myself. I should state i am a total newbie to velocity and just installed it yesterday. I've placed velocity-1.4.jar & velocity-dep-1.4 under WEB-INF/lib within my tomcat instance. my web.xml contains the following: <servlet> <servlet-name>SampleServlet</servlet-name> <servlet-class>pack1.SampleServlet</servlet-class> </servlet>
<servlet-mapping> <servlet-name>SampleServlet</servlet-name> <url-pattern>/SampleServlet</url-pattern> </servlet-mapping> and i am accessing the following url in my browser: _http://localhost:8080/velocity/SampleServlet_ (http://localhost:8080/velocity/SampleServlet) The supporting Java Code pcak1.SampleServlet is: package pack1; import java.io.IOException; import java.io.FileNotFoundException; import java.util.Properties; import java.util.Vector; import javax.servlet.ServletConfig; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.apache.velocity.Template; import org.apache.velocity.context.Context; import org.apache.velocity.servlet.VelocityServlet; import org.apache.velocity.app.Velocity; import org.apache.velocity.exception.ResourceNotFoundException; import org.apache.velocity.exception.ParseErrorException; import org.apache.log4j.*; /** * Sample of how to use the VelocityServlet. * This example shows how to add objects to the context and * pass them to the view. * * @author Dave Bryson * @author <a href="_mailto:[EMAIL PROTECTED]">Geir_ (mailto:[EMAIL PROTECTED]">Geir) Magnusson Jr.</a> * @version $Id: SampleServlet.java,v 1.5.8.1 2004/03/04 00:18:29 geirm Exp $ */ public class SampleServlet extends VelocityServlet { /** * Called by the VelocityServlet * init().
