Have you changed your build to include itext.jar in the WEB-INF/lib dir

You need to be careful with your classpaths... your web class path is different to your ear one.

Deploy a working example from the examples dir to see the layout.

Make sure these are in your WEB-INF lib

./S2JNET.war/WEB-INF/lib/itext.jar
./S2JNET.war/WEB-INF/lib/jboss-seam-ui.jar

Here is may jar layout:

./lib/commons-lang.jar
./lib/antlr-runtime.jar
./lib/drools-core.jar
./lib/drools-compiler.jar
./lib/richfaces-api-3.2.0.GA.jar
./lib/poi-3.0.2-FINAL-20080204.jar
./lib/mvel14.jar
./lib/jboss-el.jar
./lib/quartz.jar
./lib/jbpm-jpdl.jar
./S2JNET.war/WEB-INF/lib/jboss-seam-pdf.jar
./S2JNET.war/WEB-INF/lib/commons-beanutils.jar
./S2JNET.war/WEB-INF/lib/richfaces-ui-3.2.0.GA.jar
./S2JNET.war/WEB-INF/lib/richfaces-impl-3.2.0.GA.jar
./S2JNET.war/WEB-INF/lib/jboss-seam-debug.jar
./S2JNET.war/WEB-INF/lib/itext.jar
./S2JNET.war/WEB-INF/lib/jsf-facelets.jar
./S2JNET.war/WEB-INF/lib/jboss-seam-ui.jar
./S2JNET.war/WEB-INF/lib/jboss-seam-remoting.jar
./S2JNET.war/WEB-INF/lib/jboss-seam-ioc.jar
./S2JNET.war/WEB-INF/lib/commons-digester.jar
./S2JNET.war/WEB-INF/lib/jfreechart.jar
./S2JNET.war/WEB-INF/lib/jboss-seam-mail.jar
./S2JNET.war/WEB-INF/lib/jcommon.jar
./jboss-seam.jar

From seam documentation it states:

To include PDF support in your application, put jboss-seam-pdf.jar in your WEB-INF/lib directory along with the iText JAR file.

Also in Dan Allens Seam in Action Book on managing libraries, which libraries are selected to be packaged with deployment archive is controlled by deployed-jars.list file, in your case deployed-jars-war.list. You need to add entries for itext.jar and jboss-seam-pdf.jar.
