    copied!<p>Right now I'm playing with Flex and Java integration and trying to access EJB3 methods by clicking Flex button but it's giving me null pointer error.</p> <p>Here is what I have in my code:</p> <p>[Controller:] </p> <pre><code>public class homePageController { @EJB CategoryFacadeRemote categoryFacade; public String populateDBWithXMLData(){ ArrayList&lt;Category&gt; cats = new ArrayList&lt;Category&gt;(); cats = new QuestionsUtil().getCategories(); try{ categoryFacade.createMany(cats); } catch(EJBException ex){ ex.printStackTrace(); } System.out.println("SIZE: " + cats.size()); return "HIIIIII"; } } </code></pre> <p>[CategoryFacade]</p> <pre><code>@Stateless public class CategoryFacade implements CategoryFacadeLocal, CategoryFacadeRemote { @PersistenceContext private EntityManager em; public void create(Category category) { em.persist(category); } public void createMany(ArrayList&lt;Category&gt; categories){ for(int i = 0; i &lt; categories.size(); i++){ create(categories.get(i)); } } ... } </code></pre> <p>[Remote-config.xml]</p> <pre><code>... &lt;destination id="homePageController"&gt; &lt;properties&gt; &lt;source&gt;homePageController&lt;/source&gt; &lt;/properties&gt; &lt;/destination&gt; ... </code></pre> <p>[Flex App. File]</p> <pre><code>... &lt;mx:RemoteObject id="hcRO" destination="homePageController"&gt;&lt;/mx:RemoteObject&gt; &lt;mx:Script&gt; ... private function callHomePageController():void{ hcRO.addEventListener(ResultEvent.RESULT, hcROResultHandler); hcRO.addEventListener(FaultEvent.FAULT, hcROFaultHandler); hcRO.populateDBWithXMLData(); } private function hcROResultHandler(eve:ResultEvent):void{ Alert.show("RESULT:" + eve.message.body.toString()); } private function hcROFaultHandler(eve:FaultEvent):void{ Alert.show("FAULT:" + eve.message.toString()); } ]]&gt; &lt;/mx:Script&gt; &lt;mx:Button x="148" y="222" label="homePageController" click="callHomePageController()" width="262" height="43"/&gt; &lt;/mx:Application&gt; </code></pre> <p>The program works fine if I take out the call to EJB. I'm sure that the solution is easy but I can't figure it out.</p> <p>By the way, I'm using Glassfish as my app. server. </p>
