I am attempting to get my first JSF page up and running on a local instance of a was server. I can't seem to navigate to my first page. I think I have everything set up correctly, except I never get to my page.
I always get a
"the website cannot display page"
exception. When I look in the console to see what exceptions might have been thrown, the following are displayed:
E com.ibm.ws.webcontainer.webapp.WebApp logServletError SRVE0293E: [Servlet Error]-[GenericServletWrapper]: javax.portlet.PortletException: java.lang.NullPointerException
and
Caused by: java.lang.NullPointerException
at java.util.Collections.list(Collections.java:2229)
both of those exceptions are followed by stack trace entries with no real meaning to me. Those appear to be the most relevant entries.
Here's the entire stacktrace:

I'm using Neo4j 2.1.6 and Spring Data Neo4j 3.2.1. I've been using Neo4j 2.1.6 the whole time (i.e. haven't migrated from an earlier version of Neo).
I'm running into an intermittent issue where when I try to do a MATCH statement, e.g.
MATCH (p:Profile) WHERE p.username = 'abc123' RETURN p
I'm getting an EntityNotFoundException, saying things like,
Node with id 25393
A couple similar MATCH queries return similar results.
I'm noticing that the ids that aren't found are greater than the max internal node ID in the database.
I'm not exactly sure what's going on as it's intermittent.
Any help on the matter would be greatly appreciated.

It seems you have no index on :Profile(username)
So Neo (Cypher) has to scan over all :Profile nodes some of which might have been removed concurrently. So Cypher reads the id from the index, after that the node is deleted and only later it tries to load the node with that id for property comparison but it already has gone.
I think it's addressed in a more current version of Neo4j but I'm not sure.
We ran into a similar problem on Neo4j 2.2.3 and Spring Data 3.3.1.
Based on your comment to Michael's answer, it sounds like you have an index on the username property. We verified that we have a schema index against "username" using :schema in the Neo4j browser.
It seems the index is somehow corrupted. I verified this by running the same query but with a couple of twists to bypass the index:
MATCH (p:Profile) USING SCAN p:Profile WHERE p.username = 'abc123' RETURN p
MATCH (p:Profile) WITH p WHERE p.username = 'abc123' RETURN p
The above queries would work, but the original query you gave failed as described. Sometimes queries would fail by returning no results (when they should have results), and sometimes we saw some Neo4j error about a missing ID. This means the queries only work when not hitting the index.
Then running
DROP INDEX ON :Profile(username)
CREATE INDEX ON :Profile(username)
seemed to fix it, confirming that the index is corrupt. However, the whole time Neo4j claimed the username index was ONLINE. This happened multiple times, but we have no steps to reproduce.
This is likely a bug in Neo4j. My recommendation is to avoid (drop all) schema property indexes until it is fixed.
I have a chat application where I use a p:poll component to periodically check for new messages.
After I migrated from 3.5.20 to 4.0.5 I started to get random java.lang.IllegalStateException: getOutputStream() has already been called for this response(stacktrace below).
Other pages work fine, only difference between them is the poll component. Tested with Mojarra 2.1.26 and 2.2.4.
Time to the exception happen vary a lot. It can be 5 minutes, it can be 2 hours. No special interaction needed, if I just leave the page opened the exception will happen, another reason why I think the problem might be the poll component.
I'm aware that the poll component passed through some refactor in PrimeFaces 4: https://code.google.com/p/primefaces/issues/detail?id=5330
Could the modifications in the component be related? Any ideas?
Thanks in advance,
Phillip

I don't know exactly why, but problem was caused by atmosphere-runtime. Changing to atmosphere-runtime-native solved the problem.
My mistake was migrating from PF 3.5 to 4 and enabling push at the same time, so it was much harder to troubleshoot the root of the problem.
I am running into an issue trying to render.png image using jsf 2.0, where as JPG works fine
h:graphicImage library="img" name="logo.png" --> Does not work, null pointer as shown below
h:graphicImage library="img" name="logo.jpg --> No issues
Update
I see the following from Chrome Developer Tools console
Resource interpreted as Image but transferred with MIME type text/html
Not sure if I need to set the content type in web.xml

Resolved.
Seems to be an issue with the mime mappings. For some reason png is not recognized by the server. Added mime mapping for png in web.xml

Who can I fix this?
You must delete commons-logging-1.1.jar, or when you use maven, you must set this dependency to scope "provided".

Umesh Awasthi is right. You need to provide more information in order to solve this problem. If you are using spring to create your actions, here is what you need to do.
Make sure that you have struts2-spring-plugin in your classpath.
Annotate your action class with Spring's #Component. e.g. #Component("myActionName") or use java.inject.Named (JSR330) #Named. e.g. #Named("myActionName").
You also need to make another change to your struts.xml. Add the following to it
Next in your your action element instead of referencing the full class path of your action class in the class attribute use the value passed to the #Named or #Component. e.g. class="myActionName"
Hope this helps.
Contact me if you need more explanation.
