Problem with seam-pdf

robban Aug 19, 2008 2:18 PM

I have created this document:

<p:document xmlns:p="http://jboss.com/products/seam/pdf">
<p:paragraph>
This is a simple document.
</p:paragraph>
</p:document>

When i navigate to that document I get the following error:

I'm running Seam 1.2.1.GA on Jboss 4.0.5.GA.

Any ideas? Thanks

It seems that I used an old version of the iText jar. Replaced it with the one shipped with Seam 1.2.1 and problem solved.

Hello Robert,

I have not much experience with Seam and i work with Seam 2 and with seam-gen generated eclipse projects. A wrong hint from me will not make a lot damage :-).

You need the iText library in your classpath.

The generated build.xml contains a list of JARs which will packed into the EAR. Look for it in your build.xml and check if there is the iText library included.

My list follows:

<target name="ear" description="Build the EAR">
        <copy todir="${ear.dir}">
                <fileset dir="${basedir}/resources">
                        <include name="*jpdl.xml" />
                        <include name="*hibernate.cfg.xml" />
                        <include name="jbpm.cfg.xml" />
                </fileset>
                  <fileset dir="${lib.dir}">
                            <include name="jboss-seam.jar" />
                  </fileset>
                <fileset dir="${basedir}">
                        <include name="lib/jbpm*.jar" />
                        <include name="lib/jboss-el.jar" />
                        <include name="lib/drools-*.jar"/>
                        <include name="lib/core.jar"/>
                        <include name="lib/janino*.jar"/>
                        <include name="lib/antlr-*.jar"/>
                        <include name="lib/mvel*.jar"/>
                         <include name="lib/richfaces-api*.jar" />
                   <include name="lib/itext.jar*" />
                   <include name="lib/jfreechart*.jar" />
                   <include name="lib/jcommon*.jar" />
                </fileset>
        </copy>
        <copy todir="${ear.dir}/META-INF">
                <fileset dir="${basedir}/resources/META-INF">
                        <include name="application.xml" />
                        <include name="jboss-app.xml" />
                </fileset>
        </copy>
</target>

Thanks for your reply. I had already included the iText jar but as I wrote I used an old version.
