Manually configuring Seam + Facelets on Tomcat 6: ConfigurationException caused by InstantiationException

[kwutzke]

I'm manually configuring Tomcat 6 with Seam 2.2.0 GA. I have done everything as in Dan Allen's book Seam in Action (Ch.3., pages 83-87):

web.xml:

  <context-param>
    <param-name>javax.faces.DEFAULT_SUFFIX</param-name>
    <param-value>.xhtml</param-value>
  </context-param>

  ...

  <!-- Faces Servlet -->
  <servlet>
    <servlet-name>Faces Servlet</servlet-name>              
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>              
    <load-on-startup>1</load-on-startup>
  </servlet>    
       
  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>              
    <url-pattern>*.seam</url-pattern>
  </servlet-mapping>
  
  <!-- Seam Listener -->
  <listener>
    <listener-class>org.jboss.seam.servlet.SeamListener</listener-class>
  </listener>

faces-config.xml:

<faces-config version="1.2"
              xmlns="http://java.sun.com/xml/ns/javaee"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
              xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd">

  <!-- Facelets -->
  <application>
    <view-handler>com.sun.facelets.FaceletViewHandler</view-handler>
  </application>
    
</faces-config>

I did the above, but I keep getting an exception on deploying my webapp:

Does anyone know what I'm doing wrong? Which JSF and Facelets version am I using with Seam 2.2.0 GA? faces-config.xml header wrong?

Feel free to guess, I'm pretty much out of ideas.

How did you package the war file? In particular, what's in the WEB-INF/lib of your war file? The jar files of Seam and the jar files of JSF should be there. Are they? And which JSF version are you using?

[kwutzke]

I package the WAR file using Ant:

  <target name="war" depends="compile,create-manifest,copy-libraries" description="Creates the distribution WAR file">
    <!-- copy the config *.xml files to the classes build tree to end up in the WAR's /WEB-INF/classes/META-INF dir and not /META-INF -->
    <copy file="${xml.dir}/persistence.xml" todir="${build.dir}/META-INF" overwrite="true"/>
    <copy todir="${build.dir}" overwrite="true">
      <fileset dir="${src.dir}" includes="*.properties" />
    </copy>
    <war destfile="${deploy.file}"
         duplicate="fail"
         webxml="${webxml.file}"
         manifest="${manifest.file}">
      <classes dir="${build.dir}" />
      <lib dir="${lib.dir}" includes="*.jar" />
      <webinf dir="${xml.dir}" includes="web.xml" />
      <metainf dir="${xml.dir}" includes="context.xml" />
      <fileset dir="${parent.dir}" includes="${images.dir.name}/,${lang.dir.name}/" />
      <fileset dir="${web.dir}" />
    </war>
  </target>

I put all of the Seam libs into Tomcat/lib. Probably wrong as you say. I'll try that.

I'm using the version of JSF that comes with Seam 2.2.0 GA. Honestly, I have no idea which version that is. I guess 1.2?

[kwutzke]

Oh and I'm using a manually-managed local repository...

Karsten

[kwutzke]

OK I moved the files

jboss-el.jar
jboss-seam.jar
jsf-api.jar
jsf-facelets.jar
jsf-impl.jar

into the WAR and now the errors are gone. :-)

However, I'm still not able to access the Faces Servlet/XHTML. Are there any JARs I'm missing? I'm just trying to be minimal for learning purposes.

Karsten

[marcelkolsteren]

If you were still missing some JARs you would probably have had a new stack trace, showing a ClassNotFoundException. So if you still not see the page, it's probably due to an incorrect URL in the browser. If your page is WEB-INF/test.xhtml, and your war file is called foo.war you should access it in the browser with http://localhost/foo/test.seam.

[marcelkolsteren]

Correction ... you're probably running on port 8080. So it should be http://localhost:8080/foo/test.seam.

[kwutzke]

Yes correct. I have a virtual host running, but it seems to be very unreliable between server restarts.

Anyhow, I got JSTL errors and after downloading the API and IMPL JARs from https://jstl.dev.java.net/download.html I'm ready to go.

BIG THANKS for helping!

Karsten

[kwutzke]

Hmm I'm continuing the config today. When entering the URL http://localhost:8080/bbstats/list-clubs.seam I get nothing more but the display of the XHTML file (list-clubs.xhtml), including all ui tags. So the Faces Servlet isn't running, even though an hour ago I managed to invoke the Servlet (giving me classpath errors for commons-digester, commons-beanutils etc. again).

Any clues why the Faces servlet isn't running?
