    Error when using ajax and facelets

    Ahmad Atwi Newbie

      Dear All:
      i am trying to use faclets and ajax in my project (similar to the hotel booking example), i am using almost the same web.xml file:

      <?xml version="1.0" encoding="UTF-8"?>
      
      <web-app version="2.5"
       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-app_2_5.xsd">
      
       <!-- Ajax4jsf (must come first!) -->
      
       <filter>
       <display-name>Ajax4jsf Filter</display-name>
       <filter-name>ajax4jsf</filter-name>
       <filter-class>org.ajax4jsf.Filter</filter-class>
       </filter>
      
       <filter-mapping>
       <filter-name>ajax4jsf</filter-name>
       <url-pattern>*.seam</url-pattern>
       </filter-mapping>
      
       <context-param>
       <param-name>org.ajax4jsf.VIEW_HANDLERS</param-name>
       <param-value>org.jboss.seam.ui.facelet.SeamFaceletViewHandler</param-value>
       </context-param>
      


      i have added the following jar files to the project;
      jboss-seam-ui.jar
      ajax4jsf.jar

      but still i am getting the following error:
      java.lang.ClassNotFoundException: org.jboss.seam.ui.facelet.SeamFaceletViewHandler


      any idea how to solve that.
      Thanks in advance

          can you please paste your build.xml and application.xml here?

              You also need to have the oscache-2.3.2 and ajax4jsf jars to have ajax working

              • 4. Re: Error when using ajax and facelets
                Ning Zhao Apprentice

                Since there is

                <fileset id="ejb3.lib" dir="lib">
                 <include name="jboss-seam.jar" />
                 </fileset>
                in the <!--- EJB3 ---> section in your build.xml, I suppose there would be something like
                <module>
                 <java>jboss-seam.jar</java>
                 </module>

                in the application.xml. Now the question is: Is the jboss-seam.jar found by your application server when the application was deployed? If not, try to add the code list above to your application.xml.

                  Ning Zhao Apprentice

                  Ah sorry i made a mistake. That was "EJB3" section but not "EAR" section. So I guess the jboss-seam.jar may well be already be found at deploy time.

                  I modified the hotel booking example too and the packaging strategy also followed the example (your packaging is a bit different). Everything including ajax4jsf worked fine.

                  Here is my latest packaging-build.xml (it can be easily mapped to build.xml)
