          Post your config files, It sounds like your portlet.xml view-param JSF file is wrong.

            sorry, this question is solved, thanks

            another question is why I deployment portlet, but portlet instance didn't created, I must using admin to create one.

            portlet-instance.xml



            <instance-id>SimplestHelloWorldInstance</instance-id>
            <portlet-ref>SimplestHelloWorld</portlet-ref>




            Is anywhere wrong?

              Hi uxa,

              Have you created the default-object.xml or something-object.xml?

              In your case, the content of the file should be something like:

              <deployments>
               <deployment>
               <parent-ref>default</parent-ref>
               <if-exists>overwrite</if-exists>
               <page>
               <page-name>SimplestHelloWorld</page-name>
               <display-name>SimplestHelloWorld</display-name>
               <window>
               <window-name>SimplestHelloWorldWindow</window-name>
               <instance-ref>SimplestHelloWorldInstance</instance-ref>
               <region>center</region>
               <height>0</height>
               </window>
               </page>
               </deployment>
              </deployments>


              Cheers,
              JP

                Thanks jpviragine

                yes, I have the default-object.xml, but I need using admin mode to create the portlet instance for my portlet object.

                What I need to do, if I deploy portlet and I want it instance be created.

                  Uxa,

                  As you said that you have created portlet-instances.xml and default-object.xml. I think the problem is in your portlet.xml.

                  Please, take a look at: http://www.redhat.com/docs/en-US/Enterprise_Portal_Platform/4.3/html/Reference_Guide/descriptors_portlet.html for a correct usage of the three files.

                          I try to use

                          <content>
                           <content-type>portlet</content-type>
                           <content-uri>
                           SimplestHelloWorldInstance
                           </content-uri>
                           </content>
                          


                          or

                          <instance-ref>SimplestHelloWorldInstance</instance-ref>
                          


                          the result is the same
