Importing the 3 EJB files to migrate to WorkShop .ejb?

Hi,
I know how to import packaged ejb's or built .ejb files into WorkShop.
But, How can I import the standard 3 EJB files (Home Interface, Component Interface
and the Enterprise JavaBean Class) into Workshop so that it generates its .ejb
file.
I wish to import source files that I developed under another IDE and continue
my work with those files under Workshop. It seems that WorkShop has to use the
.ejb files to place it's tag. That's fine, but how do I import the 3 EJB file
so that the .ejb gets generated?
Thanks!

John, Vimala
You can import existing EJBs that you have:
1) The source for the EJBs
2) The deployable JAR file
Create a new EJB project, right click on the project or
choose from the file menu "Import EJB from jar..."
Point workshop at your source directory and the jar file
and it will create new .ejb files that you can now use
inside of workshop.
hope that helps,
-Michael

Hi John,
You can add existing EJB's to workshop application by adding an EJB JAR as a module
or as a library. To add an EJB JAR as a module, you need the complete EJB JAR
file.
You cannot just import the 3 ejb files to generate a .ejb file.
Thanks a lot,

Upgrading Stellent 7.5 to OCS 10gR3 Import Process failing HELP NEEDED

Hi,
I am upgrading Stellent 7.5 to Oracle COntent Server 10gR3. Here is what I have done.
1. Migrated all the configuration from Stellent to 10gR3
2. Migrated the Folders from Stellent to 10gR3
3. Migrated the content by creating an Archive and then importing the Archive in 10gR3.
I am seeing lot of errors in the log file. Following are the errors I see in the log file.
1.
Could not send mail message from (null) with subject line: Content Release Notification. Could not get I/O for connection to: hpmail.rtp.ppdi.com java.net.ConnectException: Connection timed out
2.
Import error for archive 'ProductionContent' in collection 'prod_idc': Invalid Metadata for 'ID_000025'. Virtual folder does not exist.
3.
Import error for archive 'ProductionContent' in collection 'prod_idc': Content item 'ID_004118' was not successfully checked in. The primary file does not exist.
4.

7.
Import error for archive 'ProductionContent' in collection 'prod_idc': Aborting. Too many errors.
QUESTIONS:
Is there a way to keep the import processing running even if the errors are coming. As it looks like when there are too many errors the import process stops in the middle.
How do I find out the total number of folders and the documents. As I want to run the same query on Stellent 7.5 and find out total number of folders and the documents and then run the same query on 10gR3 and compare the results. Just want to fnd out how much content is imported.
How do I run the import process over again as half of the content is imported and my import process failed in the middle when running the process over again what settings do I need to provide to make sure no duplicates get created etc.
Any help is really appreciated.
Thanks

Hi
There are a couple of ways to get around the issues that you are facing such that import process is not interrupted because of these. They are as follows :
1. Use ArchiveReplicationException component . This will keep the import process running and make a log of the failed process which can be used for assessing / gauging the success of the import and what all needs to be redone.
I would suggest this as the option for your case.
2. Put the config variable for arciver exception to 9999 so that the archive process stops only after hitting the limit of 9999 errors.
I would suggest to go for step 1 as that would be a much more foolproof and methodical way of knowing what all items have failed during import.

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

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.

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;

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:

Mass Excel File Project Import

Hello,
I would like to know if there is a way to mass import projects that are defined under a.xls file extension.
And also a good explanation of how can I do that or an example file.
Kind regards.

Hi Dolly,
i am using this program to create projects. There is a parent field(not sure which attribute of the project it is referring to), no matter what i give as input against this field the project creation just fails. It says "entry in structure work book missing(with XX as name / child node). i even tried disabling the selection in the spro(configure fields for mass import-DPO_STRUC)
Appreciate your quick help.
Thanks,
