[Barcode4j-users] Re: Using krysalis with Tomcat to output PDF barcodes

[Alexandre A. <aa...@pe...>]

Thanks Jeremias for your fast and encouraging answer !!!

I'm using Tomcat 4.0 but as you told me it works with a newer version,
I've set up Tomcat 5.0.28 and Java2sdk-1.4.2_05 (on another machine).
The server works, the examples work as well, then I tried to add a Fop
Servlet
but can't make it work.

I know it's not a krysalis issue...but here's what I've done:
I copy the fop folder (the one which works on Tomcat 4.0) in the webapps
folder
and when I try to access the servlet, i've got a 404 error.
Here is the web.xml file form the fop folder:

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">

<web-app>
    <servlet>
        <servlet-name>Fop</servlet-name>
        <servlet-class>FopServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
  <servlet-mapping>
    <servlet-name>Fop</servlet-name>
    <url-pattern>*.pdf</url-pattern>
  </servlet-mapping>
    <servlet-mapping>
        <servlet-name>Fop</servlet-name>
        <url-pattern>/fop</url-pattern>
    </servlet-mapping>
</web-app>

I've read information about how to set up web application in Tomcat but
haven't
found what's wrong as the fop folder is the same on Tomcat 4.0 and Tomcat
5.0.28

I tried the Krysalis Servlet on Tomcat 5.0.28 with success (but it generates
SVG,
and I need PDF....)
