NPE on file upload on fresh installation

szimano — Fri, 03 Aug 2007 11:04:02 GMT

Hello,I've recently compiled from HEAD (rev 936, before that 929) war for jboss portal by ant build-jboss. I've also set mysql database.My configuration is: JBoss AS 4.0.5 + JBoss Portal 2.6. I've removed myfaces-* from WEB-INF/lib in alfresco.war and overwritten those in jbossweb jsf-libs directory

Glad to hear you got it deployed ok, there may be a bug in Upload - can you raise it in JIRA and we'll take a look.

Thanks,

Kevin

Hi there,

I have the exact same problem coming up in Liferay. I have integrated Alfresco 2.1.0 Community to run as portlets in Liferay 4.3.6. The deploy worked. The problem occurs when I try to add content to my user space through the Alfresco main web client in Liferay.

javax.portlet.PortletException
caused by
java.lang.nullPointerException

After this error occurs in the web client, I cannot add content even when I go to http://localhost:8080/alfresco because I get a faces error there.
However, if I try to add content in alfresco before accessing liferay and trying to add content in liferay, it works. I am really confused, because I really cant find any references to this error anywhere on the internet. Can you please help? I saw the information above but I dont understand what I need to do to get this to work. Can you please give me some instructions?….Thanks!
Here is the error log that appears on the liferay page:

Re: NPE on file upload on fresh installation

Hi raul_bhatia,

I had the same problem as you and finally I have solved it following this post. You only need to modify the file "AlfrescoFacesPortlet.java" just like kevinr says in his comment, I mean:


            // it doesn't matter what the value is we just need the VIEW_ID parameter
            // to tell the faces portlet bridge to treat the request as a JSF request,
            // this will send us back to the same page we came from, which is fine for
            // most scenarios.
            //response.setRenderParameter(VIEW_ID, "a-jsf-page");
            
            // Set the VIEW_ID parameter to tell the faces portlet bridge to treat the request
            // as a JSF request, this will send us back to the previous page we came from.
            String lastViewId = (String)request.getPortletSession().getAttribute(SESSION_LAST_VIEW_ID);
            if (lastViewId != null)
            {
               response.setRenderParameter(VIEW_ID, lastViewId);
            }
         }
         else
         {
            User user = (User)request.getPortletSession().getAttribute(AuthenticationHelper.AUTHENTICATION_USER);
            if (user != null)
            {
…
…
…

        // if we have no User object in the session then an HTTP Session timeout must have occured
         // use the viewId to check that we are not already on the login page
         PortletSession session = request.getPortletSession();
         String viewId = request.getParameter(VIEW_ID);
         // keep track of last view id so we can use it as return page from multi-part requests
         request.getPortletSession().setAttribute(SESSION_LAST_VIEW_ID, viewId);
         User user = (User)request.getPortletSession().getAttribute(AuthenticationHelper.AUTHENTICATION_USER);
…
…
…
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Then you have modified your source, you only must copy the compiled file "AlfrescoFacesPortlet.class" to your Tomcat server folder (in this path: …alfresco\WEB-INF\classes\org\alfresco\web\app\portlet).

I hope this will help you,

Thanks for ypur help kevinr. Bye!!!
