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;

Kati

How can I create a new EJB project ?
Hi,
I downloaded the trial version and I don't know how to create an EJB project ?
When I create a new project, I've only the web template to choose.
Where can I find informations about that ?
Thanks.
jackHi 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.
Thanks,
Shiv
Edited by: Shiv Khullar on Aug 30, 2010 9:39 PMHi 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"/>
<classpathentry kind="lib" path="/LocalDevelopmentLocalDevelopmentexternallibrarypdftoolsforwatermarkingdemo.sap.com/gen/default/public/WatermarkCompilation/lib/java/demo.sap.comexternallibrarypdftoolsforwatermarking~WatermarkCompilation.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.

Adapter module:: JAR file in the build path of EJB project
Hi Experts,
I have created one adapter module, for this I have created one EJB project and also associated one EAR project to that.
I have completed my coding and changes in the xml files.
I have followed this -

while creating the module.
but after finishing this , I can not see the ejb.jar file corresponding to the ejb project, I can see the class file generated in the build path.
but I can not see the ejb.jar in the EJB project after build.
When I checked the EAR project I found under Deployment descriptor there is a folder called module and there is a jar file named as -
EJB<my ejb project name>.jar
when I am about to deploy this EAR in the server it is showing me to choose the file from EAR project and this EAR project contain the EJB Project .
Request you to please let me know is everything ok with my project ? or please let me know how can I see the ejb.jar file corresponding to the ejb project below the build path.
Thanks

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

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.
AnandDan,
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...

If I'm understanding your question correctly you're running
the EJB tutorial that's being shipped with the 8.1 beta correct?
I just did a quick check on my installation of the pre-beta installer
and didn't see it there so it's possible there's a bug in the installer
or something. At any rate, I've attached a zipped up copy of that
tutorial code here. Hope that helps.

EventService lookup from ejb project
hi
We want to use the EventService from with in a class which resides in an ejb project of our portal application.
We used the EventService from within the portal webapp project without problems. With
Object o = p_context.lookup( "java:comp/env/ejb/EventService" );
we could lookup the object and narrow it to the EventServiceHome interface. However this does not work within the ejb project.
We get the error message:
"javax.naming.NameNotFoundException: While trying to look up comp/env/ejb/EventService in /app/ejb/scp_helpers.jar#EJBTTHelper.; remaining name 'comp/env/ejb/EventService'"
We tried another name which we found in different depoyment descriptors: p13n_ejb.jar#EventService . No success.
What name do we have to use or shortly: what are we doing wrong? How could we get the EventService SessionBean from within an ejb project?look up the resource-ref in web.xml (and weblogic.xml). Add the same in ejb-jar.xml (and weblogic-ejb-jar.xml). The entries are not exactly the same, but the concept is the same.
