EJB project creation in Eclipse

Hi All,
i am using Eclipse 3.2 to create an EJB module.
i created a new EJB project......in it in ejbModule, i created a package and a JAVA class in it...........
when in the JAVA class, i wrote import javax.ejb.SessionBean; it gave error on javax.ejb saying "javax.ejb cant be resolved"............
Can anybody suggest how to rectify this error.
Thanks,
Rajeev Gupta

Hi All,
i created a jar file for my ejb project...........
Now i imported that jar file in a new java prj, then i am able to instantiate that ejb class in the main method of the new java prj.........
In the window i can also see all methods of the ejb class.........
My ejb-jar xml file is having the below content:
<ejb-jar id="ejb-jar_ID" version="2.1" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd">

               <ejb-class>pkgHelloWorldEJB.HelloWorldEJB</ejb-class>
               <session-type>Stateless</session-type>
               <transaction-type>Container</transaction-type>
     </enterprise-beans>
</ejb-jar>
Like i declared a function:
public String strReturn(){
          return "Hello JAVA EJB World";
When i called this function by obj.strReturn() then no compilation error was there.
<b>But when i run this JAVA prj application, it gave error java.lang.NoClassDefFoundError: pkgEJB/ClassEJB
     at pkg.class.main of JAVA prj application</b>.
Can anybody suggest me what should i do to rectify this situation.

Problem building EJB jar file using Eclipse

Hi,
Here's my file sturcture.
ejb\x\y\z\test\
ejb\x\y\z\test1\
'ejb' is the root directory.
The java source files under 'test' have a package name x.y.z.test.
The java source files under 'test1' have a package name x.y.z.test1.
I want to build a EJB jar file for 'test' and 'test1' separately. In eclipse when I create an EJB project, I specify the root folder as the source in the java build path settings. So the project explorer in Eclipse shows both the packages since they are under the same root folder. When I try to do 'Export - EJB Jar File', it includes both the 'test' and 'test1' in the .jar. Is there a way to build them separately ?
Thanks,

As far as I know, there is no way in Eclipse to specify a package prefix for a source folder. Assuming that you are not using an operating system with support for symbolic links at FS-level, the only way I can think of solving your problem is via linked folders and includes/excludes.
1. Create two ejb projects in your workspace. Specify locations somewhere independent of where the root of your source tree is located.
2. Right click on proj1 and select Properties / Java Build Path / Source.
3. Click Link Source and specify the location to your source root on disk. Click Next.
4. In the inclusion patterns section, add a pattern that captures classes appropriate for that module. Click Finish.
5. Delete the original source directory that was created during project creation before leaving Build Path configuration dialog.
6. Repeat steps 2-5 on the second project, except specify a different inclusion pattern.
This should produce a project structure that Eclipse will be happy with, but you have to be a little bit careful. Even though you filtered out classes from the view of the java compiler for a particular project, you will still see them listed in the various navigational views (such as Package Explorer or Project Explorer). Don't modify these filtered out files. The project that is supposed to be building them will not react to changes in the other project. You will have to manually refresh (right click on project and select refresh) the other project before the java compiler will see changes.
Hope this will help you out.

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:

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 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.

"add and remove projects" problem in eclipse weblogic tool 1.1.3

Hello,
i installed eclipse weblogic tool 1.1.3. When i try to add a project to the server, it cannot even list my java projects. I found out that it only list those dynamic web projects.
My question is: is it possible to add java project to server. My java project includes src and webRoot, which is deployed in weblogic 10.
Also, when i set a breakpoint in jsp. I always have the source not found problem. Is there a way to get around this?
Thanks

Hi
Java project cannot be deployed to the server standalone.
One way to do is to create a ear project and add the web project and java project to it. If you create the web project and java project after EAR project creation then you can add to ear when creating web and java projects.
But if you already have web and java projects, create a ear project and right click on ear project -> properties -> project reference -> check both projects. Also right click on ear project -> properties -> j2ee module dependencies -> check both projects.
Now build the ear project and you will see the java project part of ear and the web project can refer to the java project classes.

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.

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

Portal Service Project creation in EP5 SP5 in java

We have created on service(test) in eclipse but after build this project we are not getting testapi.jar and testcore.jar files under lib and lib\private folders.
we don't what might be the problem. Please let us know if any documents for the portal sevice project creation.

Hi Harsh
Thanks for your quick reply......
I agree with you that by flexible field mapping we can do but my concern is that service activity should have services also defined in MSP because when this will come to SAP , it will ask for services & if services are not available then this will fail.
Please suggest your opinion ..

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:

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
