  • How to connect remote EJB module from application client

    - by Zeck
    Hi guys, I have a EJB module in remote Glassfish server and application client in my computer. I want to connect from the application client to the remote EJB. Here is the my EJB interface: @Remote public interface BookEJBRemote { public String getTitle(); } Here is the my ejb: @Stateless public class BookEJB implements BookEJBRemote { @Override public String getTitle() { return "Twenty Thousand Leagues Under the Sea"; } } I have several questions : Can I use Dependency Injection in the remote application client to connect to the ejb? If so what can i do to achieve this. Do i need to configure in the sun-ejb-jar.xml and sun-application-client.xml? In other words, if i use DI like @EJB MyEJBRemote ejb; How application client container know what ejb to be injected? Where should i specify the information? How can i run the application client? I tried to run package-appclient in the glassfish server to get appclient.jar and copy it to my computer. Then i type appclient.jar -client myAppClient.jar . It didn't work. How do i point the target server? if i cannot use DI in the client then i guess i have to use JNDI lookup. Do i need to configure jndi name in sun-ejb-jar.xml or in the sun-application-client.xml? No matter how i try i never manage to run application client ? Can you guys put some working example? And thank you for every advises and examples?

  • Tomcat error with Hibernate 3.51 / Java EE 6

    - by DD
    I just upgraded to hibernate 3.51 and I get an error now saying: java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval () Z. This only happens with Tomcat not with Jetty. I've checked and I don't have any conflict and this method definitely exists. I have hibernate-jpa-2.0-api-1.0.0.Final.jar on the class path, and dont have any conflicting classes. Any suggestions?

  • Confused about using SpringMVC Vs JEE project in Netbeans

    - by Sanju
    Hi all, I want to start a my first JEE project. I have read a lot that springMVC framework is a good choice (never used though) My earlier experience with java is not much. only some small app development using Netbeans. so I have some experience using Netbeans. but I see that I can start a JEE project in Netbeans. so what kind of framework netbeans is using underneath. PS: My understanding of framework (e.g. SpringMVC) is that you follow rule of framework to configure your app. and then framework take care or linking your View, controller and model. so if i am using netbeans, do i need to take care of linking of my MVC by myself?

  • JSON Web Service over simple HTTP GET/POST

    - by whoi
    Hi; Can you suggest a way or a framework or etc. for JEE in order to make simple HTTP GET/POST calls to some web services like in SOAP web services but transport format must be JSON; not XML and there must not be any wrapper around(may be some vey lightweight header) like SOAP etc. In short, my purpose is to serve web services using JSON and HTTP Get/Post in a maximum possible lightweight solution. Thanks

  • Dependency Injection with @Inject in Weld (JSR-299 RI). How is the corresponding @Produces found?

    - by Thorbjørn Ravn Andersen
    I have played with the JSR-299 Reference Implementation "Weld" with the purpose of using it in a stand-alone application, and I have had a look at the documentation, and marveled at the magic. My question is how the producer of a given object to be @Inject'ed is found? Either the java compiler produces hints for annotations which is easily found by the classloader, or the complete classpath must be traversed loading all classes to see what they do which sounds highly inefficient to me, or it is a completely different approach. What is the trick?

  • CMIS explorer webapp

    - by Nicolas Raoul
    CMIS is a recently approved standard for accessing ECM repositories. My idea is to create a repository explorer using CMIS, under the form of an open source Java/JEE Web Application. The main interest would probably be for integrators, using it as a framework on which to quickly build repository access intranet/extranet applications. Of course, if such an open source project already exists, I would rather contribute to it rather than start a competing effort. So, does such an application/framework already exist? As open source? The only one I have found so far is chemistry-opencmis-test-browser, which is intended for tests and seems really inconvenient to extend for business use (no MVC, no IoC).

  • building a web application in eclipse

    - by Noona
    As a concluding assignment for the technologies taught in a data management course, we have to write a web application using the technologies taught throughout the course, this mostly includes xhtml, css, JSP, servelets, JDBC, AJAX, webservices. the project will eventually be deployed using tomcat. we are given the option of choosing the technologies that we see fit. since this is my first time developing a web application I am having some uncertainties about where to start, so for example now I am writing the object classes that will be used in the database and implementing the operations that will be performed on the database, but I am not sure about how to make these operations available to a client through the website, I mean I think I have to write a servlet through which I can extract the request parameters and set the response accordingly, but I would still like a more specific overview of what I am going to do, so if someone can link me to a tutorial with an example that makes use of these technologies while illustrating the stages of the design so that I can see how all these things are linked together in a web project. thanks

  • How to receive Email in JEE application

    - by Hank
    Obviously it's not so difficult to send out emails from a JEE application via JavaMail. What I am interested in is the best pattern to receive emails (notification bounces, mostly)? I am not interested in IMAP/POP3-based approaches (polling the inbox) - my application shall react to inbound emails. One approach I could think of would be Keep existing MTA (postfix on linux in my case) - ops team already knows how to configure / operate it For every mail that arrives, spawn a Java app that receives the data and sends it off via JMS. I could do this via an entry in /etc/aliases like myuser: "|/path/to/javahelper" with javahelper calling the Java app, passing STDIN along. MDB (part of JEE application) receives JMS message, parses it, detects bounce message and acts accordingly. Another approach could be Open a listening network socket on port 25 on the JEE application container. Associate a SessionBean with the socket. Bean is part of JEE application and can parse/detect bounces/handle the messages directly. Keep existing MTA as inbound relay, do all its security/spam filtering, but forward emails to myuser (that pass the filter) to the JEE application container, port 25. The first approach I have done before (albeit in a different language/setup). From a performance and (perceived) cleanliness point of view, I think the second approach is better, but it would require me to provide a proper SMTP transport implementation. Also, I don't know if it's at all possible to connect a network socket with a bean... What is your recommendation? Do you have details about the second approach?

  • httpOnly Session Cookie + Servlet 3.0 (e.g. Glassfish v3)

    - by chris_l
    By default, Glassfish v3 doesn't set the httpOnly flag on session cookies (when created as usual with request.getSession()). I know, there is a method javax.servlet.SessionCookieConfig.setHttpOnly(), but I'm not sure, if that's the best way to do it, and if yes, where the best place would be to put that line. BTW, of course it can't be done in the servlet itself (e.g. in init()): java.lang.IllegalStateException: PWC1426: Unable to configure httpOnly session tracking cookie property for servlet context /..., because this servlet context has already been initialized Generally, I would prefer to use a configuration option e.g. in web.xml.

  • How do I limit JPQ output?

    - by den-javamaniac
    I need to limit number of entities returned by a query to some certain value inside a JPA query (through JPQL). Particularly: select m from Manual m //constraint e.g. in sql (mysql syntax) I would do it like: select * from Manual limit 1 The only solution that comes up is simply to get all entities and then choose first one, which is out of the issue. Any ideas?

  • How to model in J2EE / JEE?

    - by Harry
    Let's say, I have decided to go with J(2)EE stack for my enterprise application. Now, for domain modelling (or: for designing the M of MVC), which APIs can I safely assume and use, and which I should stay away from... say, via a layer of abstraction? For example, Should I go ahead and litter my Model with calls to Hibernate/JPA API? Or, should I build an abstraction... a persistence layer of my own to avoid hard-coding against these two specific persistence APIs? Why I ask this: Few years ago, there was this Kodo API which got superseded by Hibernate. If one had designed a persistence layer and coded the rest of the model against this layer (instead of littering the Model with calls to specific vendor API), it would have allowed one to (relatively) easily switch from Kodo to Hibernate to xyz. Is it recommended to make aggressive use of the *QL provided by your persistence vendor in your domain model? I'm not aware of any real-world issues (like performance, scalability, portability, etc) arising out of a heavy use of an HQL-like language. Why I ask this: I would like to avoid, as much as possible, writing custom code when the same could be accomplished via query language that is more portable than SQL. Sorry, but I'm a complete newbie to this area. Where could I find more info on this topic? Many thanks in advance. /HS

  • EJB3.1 logout doesn't work

    - by Kevin
    Hello, I've got a problem with the authentication features of EJB3.1: With this code in a Servlet v3: log.info(""+request.getUserPrincipal()); log.info(""+request.getAuthType()); log.info("===^==="); request.logout() ; log.info(""+request.getUserPrincipal()); log.info(""+request.getAuthType()); request.authenticate(response) ; log.info("===v==="); log.info(""+request.getUserPrincipal()); log.info(""+request.getAuthType()); I would always expect to see the Username/login windows, because of the logout() function. Instead, it seems to be a 'cache' mechanism which repopulate the credential and cancel my logout ... Admin BASIC ===^=== null null ===v=== Admin BASIC is it a problem with my firefox, or something I'm missing in the Servlet code? Thanks

  • Get Ajax4JSF (a4j component) running on Glassfish

    - by yournamehere
    I'm trying to build an JEE6-application on Glassfish V3, using JSF 2.0, Weld, JPA2 and Maven. Now i'm having trouble getting a simple <a4j:support> running. This is the fragment of my little example. When typing something into the inputtext, the outputtext should automatically be updated. But nothing happens (not in Firefox, not in IE8). <ui:composition xmlns:a4j="https://ajax4jsf.dev.java.net/ajax" (...)> <h:inputText value="#{personHome.message}"> <a4j:support event="onkeyup" reRender="repeater"/> </h:inputText> <h:outputText id="repeater" value="#{personHome.message}"/> Beside that my example doesn't work, my problem is also that i don't really understand if i need a JSF implementation (MyFaces, Richfaces, Primefaces etc.) or not to use a4j elements. Is it "built-in" in glassfish? Until now, i only have the following dependencies i think i need in for JSF: <dependency> <groupId>com.sun.faces</groupId> <artifactId>jsf-api</artifactId> <version>2.0.2</version> </dependency> <dependency> <groupId>com.sun.faces</groupId> <artifactId>jsf-impl</artifactId> <version>2.0.2</version> </dependency>I'm trying to build an JEE6-application on Glassfish V3, using JSF 2.0, Weld, JPA2 and Maven. <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency> So... what do i have to do to get Ajax4JSF running on a simple JEE-App on Glassfish? Any help is highly appreciated!
