<div class="jive-rendered-content"><p>Hi</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>i'm currently new to Jboss development. I have implemented some REST services and now I want to secure them. I have implemented a SecurityInterceptor, but my problem is, I can't access my EJB's in this class.</p><p>Here ist the code of the interceptor:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-family: courier new,courier;">    @EJB</span></p><p><span style="font-family: courier new,courier;">    KryptoManager kryptoManager;</span></p><p>    </p><p><span style="font-family: courier new,courier;">    @Override</span></p><p><span style="font-family: courier new,courier;">    public boolean accept(Class c, Method method) {</span></p><p><span style="font-family: courier new,courier;">        if (c == null || method == null) return false;</span></p><p><span style="font-family: courier new,courier;">        //class implementing rest service</span></p><p><span style="font-family: courier new,courier;">        return method.getName().equals("restService");</span></p><p>        </p><p><span style="font-family: courier new,courier;">    }</span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-family: courier new,courier;">    @Override</span></p><p><span style="font-family: courier new,courier;">    public ServerResponse preProcess(HttpRequest request, ResourceMethod method)</span></p><p><span style="font-family: courier new,courier;">            throws Failure, WebApplicationException {</span></p><p><span style="font-family: courier new,courier;">        ServerResponse response = null;</span></p><p>        </p><p><span style="font-family: courier new,courier;">        String key = kryptoManager.getKryptoInformation();</span></p><p>        </p><p><span style="font-family: courier new,courier;">        ...</span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-family: courier new,courier;">        if (error) {</span></p><p><span style="font-family: courier new,courier;">            response = new ServerResponse(LOGINURL, 403, new Headers<Object>());</span></p><p><span style="font-family: courier new,courier;">        }</span></p><p>        </p><p>    </p><p><span style="font-family: courier new,courier;">        return response;</span></p><p><span style="font-family: courier new,courier;">    }</span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-family: arial,helvetica,sans-serif;">The kryptoManager always is null.

The bean access the database info and delivers them to the controlers, but in securityinterceptor this is not working, why?</span></p><p><span style="font-family: arial,helvetica,sans-serif;">Here is the rest my classes:</span></p><p style="min-height: 8pt;
