Implementing framework entity query in components.xml question, suggestion reqd

[valatharv]

Hi,

I am trying to implement framework entity query in components.xml first time. Need some information...

I have an entity "Project", seam gen created corresponding ProjectList.java which extends EntityQuery.

a) If we usign "framework:entity-query" then I cannot not use ProjectList.java ?? else I get "Two components with the same name and precedence " exception....

b) I tried testing a simple query to components.xml (removed ProjectList.java generated by seam),
when I try to access page it gives the error as mentioned below:

I am sure I am missing some configuration... please suggest.

Error :
-------
javax.servlet.ServletException: Property 'project' not found on type org.jboss.seam.framework.EntityQuery_$$_javassist_5
at javax.faces.webapp.FacesServlet.service(FacesServlet.java:277)
at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290)
at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206)

Components.xml:
---------------
<framework:entity-query name="projectList"
  ejbql="select project from Project project" scope="conversation">
  <framework:hints>
  <key>org.hibernate.comment</key>
  <value>Query for projects as result of search on /ProjectList.xhtml</value>
  </framework:hints>

  <framework:restrictions>
  <value>project.hjid=7</value>
  </framework:restrictions>

</framework:entity-query>

ProjectList.xhtml
-----------------
<rich:dataTable id="projectList"
  var="project"  value="#{projectList.resultList}"
   rendered="#{not empty projectList.resultList}">

<h:column>
#{project.projectName}
</h:column>
... etc..

Any suggestion on above issue, I tried various options but still getting exception....

"Property 'project' not found on type org.jboss.seam.framework.EntityQuery_$$_javassist_5"

Looks like mising some basic configuration.

a) This is because you defined two components with the same name and precedence ! The name of a component is not related to its Java class name: when defining the component in components.xml, the name is defined in the name attribute, when defining the component in Java code, it is defined in the @Name annotation.

b) Usually, I get this error message when I set

value="#{projectList}"

instead of

value="#{projectList.resultList}"

Thanks for replying...

For the sake of simplicity, I am just using a simple query in components.xml for Project entity, but I get this error.. where I am doing wrong, please help

-----------------------------------------
javax.el.PropertyNotFoundException: Property 'project' not found on type org.jboss.seam.framework.EntityQuery_$$_javassist_5
-----------------------------------------

Components.xml
--------------
Just added this...
<framework:entity-query name="projectList"
     ejbql="select project from Project project" scope="conversation">
</framework:entity-query>

ProjectList.xhtml
-----------------
<rich:dataTable id="projectList"
                var="project"
              value="#{projectList.resultList}"
           rendered="#{not empty projectList.resultList}">
<h:column>
    <f:facet name="header">
     <s:link styleClass="columnHeader"
             value="Project Name #{projectList.order=='projectName asc' ? messages.down :
                ( projectList.order=='projectName desc' ? messages.up : '' )}">
         <f:param name="order" value="#{projectList.order=='projectName
                  asc' ? 'projectName desc' : 'projectName asc'}"/>
     </s:link>
    </f:facet>
    #{project.projectName}
</h:column>
.....
</rich:dataTable>

Can you post the complete stacktrace ?

Thanks for your time Nicolas, I used ProjectList.java generated by seam(looks like it is required) and changed the component name in components.xml, it seems to be fine as of now.

Thanks
