Servlet packed in EJB project

Hi, I have a few servlets are pacakged in the same project as some EJBs in OEPE as a EJB project. Will the servlets work? The first try I got 404 error.

As of Java EE 6, you can put EJBs into a web application so they are deployed as part of a single WAR file -- the classes simply go into the WEB-INF/classes or packaged into jars and placed in WEB-INF/lib directory.
Putting servlets in an EJB JAR file won't work outright since the web container doesn't recognize a jar as a web application.

  • Configuring Log4j for a EJB Project.

    Hi,
    I have a weblogic EJB project as a Ear file. The project has no web components (so war file). I want to know which is the ideal way to initialize log4j in this situation.
    I can use listener class thro' weblogic-application.xml. But there is no neat way to passing the log4j.xml thro' parameter from weblogic-applicaiton.xml file.
    If we are using servlet we could use init-parm to passing xml file. I don't want to hard code the xml file location in the listener class.
    What is the best practice to initialize log4j for a EJB project?
    Thanks in advance.
    Anand

    Dan,
    I had a similar problem because I wanted to define my own log4j config regardless of what other portal apps were deployed in the BEA domain or what log4j was the default for the domain. This is what I do:
    1) Put your log4j config file in the WEB-INF classes dir (or I guess it could be in some other place that the CLASSPATH knows of)
    2) Create a servlet that looks like:
    import javax.servlet.*;
    import javax.servlet.http.*;
    import org.apache.log4j.xml.*;
    public class Log4jInitServlet extends HttpServlet {
    private static final long serialVersionUID = 23456;
    public void init(ServletConfig config) throws ServletException {
    super.init(config);
    DOMConfigurator.configure(Thread.currentThread().getContextClassLoader().getResource("myLog4jConfigFile.xml"));
    public void doGet(HttpServletRequest req, HttpServletResponse resp) {
    3) Add the servlet definition in the web.xml and add a <load-on-startup>1</load-on-startup>
    That should do it.

  • Using swing to develop EJB project

    Hi, Folks
    I am using jbuilder7 to develop swing connect to ejb project, one requirement is that i should doing control with the editable table. That requirement make me to tied with JBuilder component JDBTable. However the development time would become remarkable long. does anybody have experience of using fancy swing and EJB in the same project?
    thansk in advance.

    forget to tell you I am using JDBTable already. the problem is that how
    could i serlize the dataset to EJB in a easy way? ok, you don't need to serialize your dataset to trasmit to server side. Class com.borland.dx.dataset.DataSetData implements Serializable interface already, so you can send your dataset to server and do not care about serialization. But what to do with this DataSet on server side is very interesting question ;). As for me, it's not very handly to pull out your data from Dataset on server side (DataSet "looks" like client-side class). But, of course, it's up to you.
    unfortunlly I should doing add, delete, edit from my table. So its
    pretty complex to deal with this sort of issue.Why complex? I don't think so. For example, you may set 2 buttons: "Set" and "Delete" under your Jtable view and just "to fish" data client entered in your Jtable string, pack this data in your own serializable model and send this data to server session facade. As for me that's very handly and fast. And there is no complexity...

  • JPA facet in EJB project

    Hi!
    Trying to develop ejb 3 project. No problem creating ejb3 session beans.
    But I'm not able to enable JPA facet in ejb project. Only supported in web project.
    Can this be true? Is support for EJB 3/JPA still lacking even in 10.3 version?
    Very disapointing....
    Regards,
    Jesper

    To clarify...
    There is no support for JPA in EJB projects in Workshop. Workshop JPA tools can only be used in web projects.
    Base Eclipse, however, comes with a different set of JPA tools that can be used with EJB or Utility projects. Oracle Enterprise Pack for Eclipse (OEPE) works with this JPA toolset (unlike Workshop). Version 1.0 of OEPE is already available (see link that Danny provided). The next version of OEPE (available in Q1 of 2009) will include additional JPA functionality that is even better than similar functionality currently available in Workshop. All of the new JPA functionality coming in the next OEPE release will be supported for Web, EJB and Utility projects.
    Hope this helps.

    Hi,
    I think your ejb doesn't contain primary key definition.
    From your exception:
    Caused by: Exception [TOPLINK-7161] (Oracle TopLink Essentials - 2006.8 (Build 060829)): oracle.toplink.essentials.exceptions.ValidationException
    Exception Description: Entity class [class project_ejb.Test] has no primary key specified. It should define either an @Id, @EmbeddedId or an @IdClass.
    You can use the @Id annotation on the primary key field(s).
    For example:
    @Id
    @Column(name="INVOICE_NR", nullable = false)
    private Long invoiceNr;

    Hi Jack,
    This version of the Creator allows you to build applications which access existing EJB's, but doesn't create new EJB's from scratch. We are looking into that for future releases.
    If you want to access an existing EJB, please see the tutorials:
    http://devservices.sun.com/premium/jscreator/standard/learning/tutorials/sessionEJBcomps.pdf
    I believe the Sun Java Studio Standard product can help you create EJB's today, if that's what you need:

  • How to call external jar files in EJB project for CE

    Hi,
    I would be thankful if someone could help me with this -
    I need to call the external jar files into my EJB project - Here is what I have done and am getting runtime exception as  -
    java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
    1. Created a EJB  project" HelloWorld "  using Java perspective in NWDS 7.1 called with client as HelloWorldClient and EAR project as HelloWorldEAR.
    2. Am working on HelloWorld project (1st one).
    3. In my code I am instantiating a class which is a class in one of  the external jar file that I need to refer in my project.
    4. I have set the Java Build path but it works only for the compile time and fails during runtime.
    5. Have read I need to create external library DC and refer in my project "HelloWorld".
    Can anyone help me with exact steps what needs to be done - during creation of external library project and then for my "HelloWorld" EJB project. How would I be able to reference or set the external library project in my EJB project?
    Looking forward to hear from experts.

    Hi Edson,
    I tried it , but it still gives me runtime exception.
    javax.ejb.EJBException: nested exception is: java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
    java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/glance/pdf/pt/PTDoc
    Steps I performed are -
    1. Created a library project and created 2 Public parts "Compilation" and "Assembly"
    2. Build the library project.
    Now in my EJB project using Project Explorer - set the classpath and added both compilation jar and assembly jar files.
    This is how the classpath entries for external library looks like -
    <classpathentry kind="lib" path="/LocalDevelopmentLocalDevelopmentexternallibrarypdftoolsforwatermarkingdemo.sap.com/gen/default/public/WatermarkAssembly/lib/java/demo.sap.comexternallibrarypdftoolsforwatermarking~WatermarkAssembly.jar"/>

    I have also added the jar files I used in my external library project as "User Library" from Java Build Path . I dont do it , then the code fails during compilation itself.

  • EJB project IDE build dos not include properties files

    We have property files also which we want included as part of the build process
    for EJB projects but if we use the IDE build it does not include them. We have
    to therefore export the IDE build and customize it to include *.properties like
    this
    <zip basedir="${dest.path}" zipfile="${ejb.outputJar}" encoding="UTF8"> <!-- JARs
    filenames are encoded UTF8 --> <zipfileset dir="${project.local.directory}" includes="*.properties"
    /> </zip>
    which causes a problem for us because the exported build file is specific to a
    user's local PC and cannot be used in a team environment.
    How can we have the IDE build include all the files within an EJB project i.e.
    include properties files also.

    Hey Jamie,
    Currently there is no support to include other .properties files into
    the internal build. There's a build.properties that you get as part of
    an EJB project which you could place your values into and use that as
    your template for your team based development and check that into your
    source control.
    If you'd really like to get gross and hack Workshop a little bit you
    could modify the default EJB project template to use your .properties
    file for every EJB project you create. This would then splat a copy of
    your .properties file into the root of the EJB project.
    To do that you'd go to {your BEAHOME}\workshop\templates and crack open
    the ejb-project.zip template zip file and merge your settings into the
    existing build.properties file. This has the same
    effect as replacing the .properties file after you've created your
    project only it keeps you from having to perform that step each time.
    The downside of this is that each person on your team would then have to
    update that template zip file in their workshop installation. (I'd make
    sure to backup the original template file before performing this
    activity so you can always go back to the original template).
    Hope this helps,
    -Michael
