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
