    Cannot Render: Object Not Found

    David W. Yutzy Newbie

      Just downloaded latest version of BETA portal and took a portlet I know works under Pluto, Sun Portal using JSR168, created the .xml files required by JBoss Portal and got:

      Cannot Render: Object Not Found

      I checked and double-checked the format of the XML files and I didn't see any errors in the logs; everything points to the portlet deploying fine.

      What should I be looking for next?

          Post the jboss portal descriptors, so we can have a look.

                    OK...

                    The only thing I can assume from lack of responses is that this is a legit error in JBoss...

                      For one, your instances.xml is wrong: http://docs.jboss.com/jbportal/v2.4/reference-guide/en/html/xmldescriptors.html#d0e2447

                      Are there any errors on boot? Initial boot?

                        How is it wrong? Remember, I submitted the first one, then the second on the request to change and both resulted in errors.

                        I followed the directions and don't see the problem you see, could yoube more specific?

                          Wrap your instance descriptor with

                          <deployments>
                          <deployment
                          ...

                            Still no go. I changed the instance file as follows:

                            <?xml version="1.0" standalone="yes"?>
                            <deployments>

                             <instances>
                             <instance>
                             <instance-id>SFRequestsInstance</instance-id>
                             <portlet-ref>SFRequests</portlet-ref>
                             </instance>
                             </instances>
                             </deployment>
                            </deployments>
                            


                            and got this exception

                              No. Look at the doc:

                              I'm assuming you're using 2.4? If not, let me know. Also, can you please try with CR1 or CR2 of 2.4 and not the Beta?

                              Please do a clean install, or use the bundle with hypersonic, to isolate any other problems that may be occurring.

                                Ok, that got it deployed!

                                What's really, really wierd is the portal/portlet appears to be working fine, but it's throwing a butt-load of exceptions in the JBoss window.

                                I can post some if you want for reference...

                                  Hello Barddzen,

                                  Did you get this issue figured out, I have the exact problem. The portlet window renders but I get the following error for the portlet page.

                                  Object not found HelloMiroApp.HelloMiroPortlet

                                  HelloMiro is the simple portlet and class name I use as the portlet. Let me know what you found out about your problem deploying.
