EJB injection nullpointer and jsf grammar not found

[Zdenek Obst]

Hi,

I got 2 problems in my project:

1) I know this topic was here before, but I couldnt find solution working for me. I have netbeans project using jsf+facelets in web application. And then ejb module.
My problem is when I call ejb from managed (backing) bean, I recieve NullPointerException. It seems that container cannot instantialize bean.

2) During reading config faces-config I got exception, that document is invalid and grammar is not found. Googled it and the problem could be using JSF1.1 grammar components in JSF1.2? Is it possible? Or where the problem could be? I have installed NB 6.7.1 with facelets plugin installed. (project works with this exception btw, but.. :-) )

Code and exceptions:

javax.faces.FacesException: javax.el.ELException: /novinky.xhtml @48,61 value="#{info.lastMatches}": javax.faces.el.EvaluationException: cz.sh.shliga.web.mb.InfoMB
............ long. stack
Caused by: java.lang.NullPointerException
at cz.sh.shliga.web.mb.InfoMB.getLastMatches(InfoMB.java:63) 

For invoking ejb method i use classic @EJB annotation.

InfoMB:

@EJB(name = "dao")
private MainDAORemote dao;

  public List<GameMatch> getLastMatches() {
        return dao.getLastMatches(); // in bean are static data so far
    }

Tried reinstalling GlassFish, Netbeans btw.

Still same problem. Mainly with EJB injection, still getting NullPointerException. Here is full stack trace after invoking simple method haha

You will have to check the documentation of Glassfish, to see whether the version you are using support EJB injection in JSF managed beans.

I found out that, if I create now pure JSF project (with default ViewHandler) and so on, calling ejb is ok and injection works. But if I create project and also add Facelets as framework, I', getting NullPointerException. Im using netbeans 6.7.1 and its plugin for Facelets support.

Since this appears to be IDE specific, i'll move this to the IDE forum.
