Setting up an ajax4jsf + trinidad project

dustismo Mar 1, 2007 8:19 PM

I am trying to set up a new project using ajax4jsf+trinidad and having problems. I have followed this doc: http://wiki.apache.org/myfaces/TrinidadSeamAjax4JsfFaceletDetail

I am getting this error:

17:12:13,846 INFO [StartupServletContextListener] Serialization provider : class org.apache.myfaces.shared_impl.util.serial.DefaultSerialFactory
17:12:13,878 ERROR [STDERR] Mar 1, 2007 5:12:13 PM org.apache.myfaces.trinidad.webapp.TrinidadFilter init

I added the trinidad and a4j-trinidad jar to WEB-INF/lib (and added them to the build.xml to be added to the ear) -- Is that right???

this is my web.xml:

<?xml version="1.0" ?>

Hello,

added the trinidad and a4j-trinidad jar

Can you be more specefic? trinidad-api-incubator-m1-SNAPSHOT.jar and trinidad-impl-incubator-m1-SNAPSHOT.jar?

to WEB-INF/lib and added them to the build.xml to be added to the ear

are they copied in the root of the project ear or in the WEB-INF/lib of the project war?

About the config files, mines are below.

Pierre

Be careful, which version of Seam you are using: The one atao is using is for Seam 1.1.6 whereas dustismo´s is for 1.2.0.

But as far as I can see from the exception you simply did not include the trinidad-jars properly. Check if you´ve got both jars, the "impl" and the "api" and also include them in your manifest.mf of your jar.

dustismo Mar 2, 2007 3:12 PM (in response to dustismo)

You were right, I didn't have the impl jar in there. So now everything starts with no exceptions but I'm not sure its working.

I set up the project using seam-gen (so I assume the jars are automatically added to the jar manifest by the build script).

<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" />
 <include name="security.drl" />
 </fileset>
 <fileset dir="${lib.dir}">
 <include name="jboss-seam.jar" />
 <include name="jbpm*.jar" />
 <include name="el-*.jar" />
 <include name="drools-*.jar"/>
 <include name="janino-*.jar"/>
 <include name="antlr-*.jar"/>
 <include name="commons-jci-*.jar"/>
 <include name="stringtemplate-*.jar"/>
 </fileset>
 <!-- Added for trinidad -->
 <fileset dir="${basedir}/resources/WEB-INF/lib">
 <include name="*.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>

I have never used trinidad before so I am just trying to see if it is configured properly..

I add this xhtml page

<!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
 xmlns:s="http://jboss.com/products/seam/taglib"
 xmlns:ui="http://java.sun.com/jsf/facelets"
 xmlns:f="http://java.sun.com/jsf/core"
 xmlns:h="http://java.sun.com/jsf/html"
 xmlns:tr="http://myfaces.apache.org/"
 template="layout/template.xhtml">

<ui:define name="body">

 <tr:document title="NavigationModel Demo" maximized="true">
 <tr:form>
 <tr:panelPage>
 <f:facet name="branding">
 <tr:panelGroup layout="horizontal">
 <tr:objectIcon name="logo"/>
 <tr:outputText value="NavigationModel Demo"/>
 </tr:panelGroup>
 </f:facet>
 </tr:panelPage>
 </tr:form>
 </tr:document>
</ui:define>
</ui:composition>

which just renders the <tr:> elements directly into the html.
