    Configure RichFaces for rich:tree


      I have had all sorts of problems getting the RichFaces tree control to work. When I try to bind a method to the adviseNodeOpened attribute on the tree control, I get a methodnotfound exception. I have found that one work around to this is to set the JBossWebLoader to true in the jboss-service.xml file. However, this breaks the SEAM email functionality, plus, I would prefer not to change the default JBoss configuration just to get a tree control to work. I have found this post on the old SEAM forum:


      Unfortunately, I need a little help understanding his directions.

      <class-loading java2ClassLoadingCompliance="false">

      First with the instruction for the class loader, by your-app-name does this mean the application name found in the application.xml file for my ear?


      and add the richfaces-impl.jar to the ejb context (richfaces-api.jar and richfaces-ui.jar go into the root ear context)

      Does this mean to put the richfaces-impl.jar into my .WAR web-inf/lib directory and put the richfaces-api.jar and the richfaces-ui.jar into my EAR lib directory? Is so, this seems to controdict the instructions on the Seam 2.0 migration guide where it states:

        ajax4jsf.jar and richfaces.jar have been replaced by
      richfaces-api.jar (which should go in your ear lib/ directory) and
      richfaces-impl.jar and richfaces-ui.jar (both of which go in WEB-INF/lib).

          If you do not want to change the classloading configuration you can put all the jar in the lib dir of your ear so they have the same classloader.

            I tried your suggestion but get the following:

            Caused by: java.lang.NoClassDefFoundError: org/apache/commons/digester/Digester

            This came when I removed the richface jars from the War/web-inf directory into the ear lib.

              Class-Path: lib/

              in you war/META-INF/MANIFEST.MF and move libs into ear/lib. This works for me.
              If you want to keep libs directly in ear/ then try

              Class-Path: /

              but I haven't tried it.

                Thanks for the suggestion. That did the trick. It is working fine now. I assume there are no side affects with moving all jars from the war lib directory to the ear lib directory.

                  Are you moving all libs from *.war/WEB-INF/lib to ear/lib? or just richfaces libraries?

                  I have exploded war so I do not have META-INF there, I expect you mean to create one?

                    Ok I got something stable.

                    1. richfaces + seam mail works

                    2. Not extra class load configuration necessary (no modification of java2ClassLoadingCompliance)

                    3. No extra meta-file necessary

                    4. RichFaces 3.2.1 seam 2.0.3.CR1

                    • in app.war/WEB-INF/lib are jboss-seam-*.jar (6 in total)

                    • in app.ear/lib is everything else. (commons*..,richfaces*..,drools..,antlr,janino,core,jboss-el,easy-jclaim,jbpm,jsf,mvel..)

                    seems work..

                      The following change to the build.xml did the trick for me:

                      <copy todir="${war.dir}/WEB-INF/lib">
                                              <fileset dir="${lib.dir}">
                                                   <include name="jboss-seam-*.jar"/>
                                                      <includesfile name="deployed-jars-war.list" />
                                                      <exclude name="jboss-seam-gen.jar" />
                        <copy todir="${ear.dir}/lib">
                                              <fileset dir="${lib.dir}">
                                                      <includesfile name="deployed-jars-ear.list" />
                                                   <includesfile name="deployed-jars-war.list"/>
                                                   <exclude name="jboss-seam-*.jar"/>
                                                   <exclude name="jboss-seam-gen.jar" />

                        I've moved richfaces-ui/api/iml to ear/lib, but I was getting strange NullPointerException in NamespaceHanlder. I had to move jsf-facelets to ear/lib also.
