EJB Project couldnu00B4t be created

Hello,
I updated my NW Developer Studio to 2.0.15, Build id: 200511290548. Now the problem occurs that I cannot create a new EJB Project. Following error is shown up: New project couln´t be created.
In the log the error starts with following message:
!ENTRY com.sap.ide.metamodel.core 1 1 Jul 31, 2006 14:38:19.281
!MESSAGE Updating metamodel archives from classpath for project MailAdapterModule

Any ideas?

Hi Michael,
I have heard of (and experienced) a number of different issues with NWDS SP15. Rather than trying to fight it, you could try installing SP16 or SP17 and see if that solves the problem.

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.
jack

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.
Thanks,
Shiv

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"/>
<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.

Shiv

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 -
http://www.sdn.sap.com/irj/scn/index;jsessionid=(J2EE3417500)ID1494558950DB01504425675464955468End?rid=/library/uuid/c0b39e65-981e-2b10-1c9c-fc3f8e6747fa&overridelayout=true
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">  <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.
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.

Re: Tutorial: Using an EJB Project

I am a computer engineering student who is learning weblogic. I appreciate if
anyone can help me with my question on Using an EJB Project
This tutorial can be found in weblogic 8.1: go to workshop ->help->Tutorials and

Hi Jessica,
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.

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:

You can use the @Id annotation on the primary key field(s).
For example:

@Column(name="INVOICE_NR", nullable = false)
private Long invoiceNr;

Can't use JPA facet in a Workshop 10.3 EJB project

Greetings,
I'm using Oracle Workshop for WebLogic 10.3 to migrate an enterprise application from JBoss 5.0 to WebLogic 10.3. I'm a bit confused as, while I can add the JPA facet to a Dynamic Web project, I cannot do the same with an EJB project. I'd need to take advantage of the IDE automatic facets management instead to manually dealing with libraries and dependencies. I beleive that this is the reason these facets exist. However, after having created a EJB 3.0 project, it is impossible to add to it the JPA facet. I had to define the JPA entities in a Dynamic Web project as this is the only one to which I can add the JPA facet. This is not regular. Additionally, the SLSB facades may only be defined in an EJB project. They reference the JPA entities in the Dynamic Web project which, given the class loading hierarchy, is not possible. So my question is: how is one supposed to use JPA with WTP projects ?
Many thanks in advance for any help,
Nicolas

This isn't supported in Workshop 10.3 and prior, the JPA tooling only works with Dynamic Web Projects in those releases to my knowledge.
I think this changed in OEPE 11g. Check out this article that shows JPA being used in the context of a Utility Project:
http://www.oracle.com/technology/pub/articles/cioroianu-eclipse-jpa.html
