Cannot get itext to work using Eclipse seam development tool

comatosehacker Jan 30, 2008 7:16 AM

I am attempting to use itext from the Seam development tools in eclipse. However I always get an exception when visiting the page. The following is the process I followed to create a simple web project.

Using Eclipse 3.3.1 / JBoss-4.2.2.GA AS / JBoss Seam - 2.0.0.GA

New Seam WEB Project using JBoss 4.2 Runtime, JBoss 4.2 Server and Dynamic Web Project with Seam 2.0 (technology preview)

The database is MySQL 5 with MySQL JDBC Driver, but this isn't used.

In the project I create a new XHTNL file with contents

<p:document xmlns:ui="http://java.sun.com/jsf/facelets"
 xmlns:f="http://java.sun.com/jsf/core"
 xmlns:p="http://jboss.com/products/seam/pdf">

<p:paragraph>HELLO WORLD</p:paragraph>

</p:document>

I have Added jcommon.jar/itext.jar and jfreechart.jar to Web App Librarie (jboss-seam-pdf.jar already there), and checked they are exported.

Added the following to web.xml

<servlet>
 <servlet-name>Document Store Servlet</servlet-name>
 <servlet-class>org.jboss.seam.pdf.DocumentStoreServlet</servlet-class>
 </servlet>

 <servlet-mapping>
 <servlet-name>Document Store Servlet</servlet-name>
 <url-pattern>*.pdf</url-pattern>
 </servlet-mapping>

Console
