Configure RichFaces for rich:tree

[jfrankman]

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:

http://jboss.com/index.html?module=bb&op=viewtopic&t=126041

Unfortunately, I need a little help understanding his directions.

<class-loading java2ClassLoadingCompliance="false">

    <loader-repository>

        seam.jboss.org:loader=<your-app-name>

        <loader-repository-config>java2ParentDelegation=false</loader-repository-config>

    </loader-repository>

</class-loading>

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?

Second:

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  ajax4jsf.jar and richfaces.jar have been replaced by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.

Put

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.

Thanks.

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?

Thanks.

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" />
                               -->
                        </fileset>
                </copy>


  <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" />
                        </fileset>
                </copy>

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.
