[EJB3] - EJB EntityManager results in NullPointerException

by Ibragim Gapuraev

Ibragim Gapuraev [https://community.jboss.org/people/sermilion] created the discussion "EJB EntityManager results in NullPointerException" To view the discussion, visit: https://community.jboss.org/message/825825#825825 -------------------------------------------------------------- I have an error that I cannot logically understand. I am implementing RSS processing app. The logic is that user takes link of some RSS feed and adds to database. If the feed already exist in database, it takes the id of feed and adds it to subscriptions of the user. Here is the code: if (existfeed == null) { feed = loadFeed(url, syndfeed); em.persist(feed); if (feed.getFeedId() == null) { return "Persist of feed failed"; } uf.setFeedId(feed); uf.setUserId(user_id); try { em.persist(uf); loadFeedItems(syndfeed, feed); //boolean ufadded = uf.addUserFeed(em); } catch (NoResultException ex) { return "Persist of userfeed failed"; } catch (PersistenceException ex) { return "Persist of userfeed failed, em"; } //boolean ufadded = uf.addUserFeed(em); //return true; return "Feed added"; } else { dbFeed = getFeed(feed.getLink()); if(dbFeed==null) return "Faile to get feed from database"; //http://appleinsider.ru/feed uf.setFeedId(dbFeed); uf.setUserId(user_id); try { em.persist(uf); } catch (PersistenceException ex) { //System.out.println(ex.getMessage()); return "Unable to persist userfeed"; } return "Feed added, existing"; } However, if user added a feed, another user cannot add it and there is the error: Caused by: java.lang.NullPointerException at ejb.FeedBean.addNewFeed(FeedBean.java:203) [Group_7_Impl_uwx09sua-ejb.jar:] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [classes.jar:1.6.0_51] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) [classes.jar:1.6.0_51] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) [classes.jar:1.6.0_51] at java.lang.reflect.Method.invoke(Method.java:597) [classes.jar:1.6.0_51] at org.jboss.as.ee.component.ManagedReferenceMethodInterceptorFactory I just dont see why would it fail. One of my opinion is that possibly, EntityManager somehow is null. But, in first part of if statement it works. I tried to use EntityManager find method, it resulted same error. So, definitely, EntityManager is somehow null in second part of if statement. Thanx for all the help. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/825825#825825] Start a new discussion in EJB3 at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[JBoss Tools] - To all you Keplers out here - Beta2 is here

by Max Rydahl Andersen

Max Rydahl Andersen [https://community.jboss.org/people/maxandersen] created the blog post: "To all you Keplers out here - Beta2 is here" To view the blog post, visit: https://community.jboss.org/community/tools/blog/2013/07/01/to-all-you-ke... -------------------------------------------------------------- Kepler was released last week, time to try out Beta2 of JBoss Tools and Developer Studio! h3. JBoss Tools 4.1 and Developer Studio 7 Beta 1 +Easier, Better, Faster + Developer Studio: [ http://devstudio.jboss.com/earlyaccess Download] | Tools: [ http://marketplace.eclipse.org/content/jboss-tools-kepler Marketplace] [ http://www.jboss.org/tools/download Download] [ http://download.jboss.org/jbosstools/updates/development/kepler/ Update Site] | [ http://docs.jboss.org/tools/whatsnew What's New] [ http://www.jboss.com/index.html?module=bb&op=viewforum&f=201 Forums] [ http://jira.jboss.com/jira/browse/JBIDE JIRA] [ http://twitter.com/jbosstools Twitter] JBoss Tools is a set of plugins for Eclipse that complements, enhances and goes beyond the support that exists for JBoss and related technologies in the default Eclipse distribution. JBoss Developer Studio is a fully bundled Eclipse distribution which not only includes the majority of JBoss Tools but also all its needed dependencies and 3rd party plugins, allowing for an easy one-click and no-fuss installation. If you are into doing your own bleeding edge eclipse plugin assembly, JBoss Tools is for you; if you are more into having something that "Just Works" then JBoss Developer Studio is the way to go. h1. Installation This release is our second Beta and is built against http://www.eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/... Kepler RC3 (Eclipse 4.3RC3) but will work with the just released final Kepler version too. But when you report issues please mention which Eclipse Kepler build and package you used. >From within Eclipse Kepler you can use the Marketplace or http://devstudio.jboss.com/earlyaccess Download Developer Studio and be sure to have the exact correct Eclipse base. h1. Improvements Beta2 are a lot of bug fixing but we do have a few improvements too. h3. WildFly 8 WildFly now has its own (experimental) dedicated server adapter. http://docs.jboss.org/tools/whatsnew/as/images/wildfly.png http://docs.jboss.org/tools/whatsnew/as/images/wildfly.png h3. LiveReload The LiveReload feature to have your webrowser or BrowerSim automatically load webpages when they changes is now easier to use than ever. You can now right click on files in the Project Explorer or on modules deployed to a server to load your Browser with a LiveReload enabled page. http://docs.jboss.org/tools/whatsnew/images/LiveReload_open_in_web_browse... http://docs.jboss.org/tools/whatsnew/images/LiveReload_open_in_web_browse... This action will setup the LiveReload server for you if it not already exist, meaning you can just focus on doing development. In addition to local development and testing you can now also easily load the page on a mobile device such as a phone or tablet via "Web Browser on External device..." http://docs.jboss.org/tools/whatsnew/images/LiveReload_open_in_web_browse... http://docs.jboss.org/tools/whatsnew/images/LiveReload_open_in_web_browse... With this you can use a QR reader application and have the webpage load through the LiveReload proxy server and it will have LiveReload injected into the pages making it automatically reload when you change your website. h3. OpenShift own Source and Markers OpenShift had a good deal of improvements usability wise this time around which you can see on its http://docs.jboss.org/tools/whatsnew/openshift/openshift-news-2.5.0.Beta2... N&N page. Two new features that are extra nice to know about is "Advanced Source Code" and "Marker configuration". "Advanced Source code" let you create an application seeded from a remote git repository server side instead of you or tools having to use git recursive merges locally. http://docs.jboss.org/tools/whatsnew/openshift/images/advanced-source-cod... http://docs.jboss.org/tools/whatsnew/openshift/images/advanced-source-cod... The other feature is to easily setup and edit so called OpenShift Markers. These are files hidden inside .openshift to enable/disable certain features. OpenShift Tools now have a UI to manage these. http://docs.jboss.org/tools/whatsnew/openshift/images/configre-markers-wi... http://docs.jboss.org/tools/whatsnew/openshift/images/configre-markers-wi... h3. More HTML5/Mobile The html5/mobile jquery palette added added support for more native HTML5 components like <video> and others: http://docs.jboss.org/tools/whatsnew/jst/images/4.1.0.Beta2/video.png http://docs.jboss.org/tools/whatsnew/jst/images/4.1.0.Beta2/video.png h2. Giving Feedback There are more news and screenshots in http://docs.jboss.org/tools/whatsnew What's New, and if you got an idea to an improvement or found a bug do not hestiate to open an issue in our https://jira.jboss.org/jira/browse/JBIDE issue tracker. h2. What's Next ? Next planned item is the candidate release and with GA this summer. Do try out this release and give feedback! ...And don't forget all the http://docs.jboss.org/tools/whatsnew/ other features that have been added in this release stream. Have fun! -------------------------------------------------------------- Comment by going to Community [https://community.jboss.org/community/tools/blog/2013/07/01/to-all-you-ke...]

Unforturtunately, wildfly over RSE (on a remote system) does not function as we'd want. But for a local jboss installation of wildfly, everything should work properly. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/825717#825717] Start a new discussion in JBoss Tools at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]
