How to Define a Data Source in a Standard Way for EJB 3.0?

I have an EJB 3.0 project that I want to deploy to different kinds of servers. I got it to work for OC4J, but when I tried to deploy it to JBoss I found out really quick that there are actually no data sources defined in my EJB Jar and that JDeveloper does not (that I am aware of) define data sources by default in a portable way.
I could be wrong on this. Not sure. Any info for explicitly defining data sources for EJB 3.0 in a portable way would be greatly appreciated.
Thank You,
KurzHome

Frank,
Thanks for your response. I will try that.
One thing I am confused about is how to link the EJB and the data source name. Unless I am missing something obvious, I can't find a configuration setting that explicitly states that my Entity EJB uses XYZ data source (when using OC4J). Where is this defined? Also, what configuration do I add to to my EJB or other file to link it to the JBoss defined data source?
Thanks,
KurzHome

Does mapping to JNDI for ejb-refs have a performance impact?

Does mapping to JNDI names for ejb-refs have a performance impact for
WLS6.1?
In the ejb-jar.xml deployment descriptor, you can define an ejb reference as
follows:
<ejb-ref>
<ejb-ref-name>ejb/AccountHomeRemote</ejb-ref-name>
<ejb-ref-type>Entity</ejb-ref-type>
<home>com.package structure.AccountHomeRemote</home>
<remote>com.package structure.AccountRemote</remote>

</ejb-ref>
Now, optionally, you can use the ejb-link element - or - you can, in the
weblogic DD, specify a JNDI name that the ejb-ref maps to.
Using a JNDI name buys you some flexibility. If, for some reason, the jar is
divided, you dont have to convert ejb-link's to JNDI names. The question is:
Is there a performance cost in doing this?
Cheers

Hi Aashish,
Thanks for your quick reply. it was helpful, but i am not using RFC's. Correct me if i am wrong, but i have explained the scenarios in detail below.
Scenario 1. Synchronous
1) PI Picks file from a common folder.
2) PI does a data mapping and sends the data to ECC.
3) ECC contains an inbound interface which receives the data and in which abap proxy code is written.
4) The abap proxy code executes a function module and sends the response as an internal table back to PI.
5) PI receives the response and places it in a text/csv file and places it back to another folder.
I assume that the above would be possible only using BPM. What i understand is that in order for an interface to receive and send data, abstract mappings are to be used, and for this BPM is required. We do not have any conversions etc. its just a simple matter of receiving an internal table from ECC and creating a file to place in the folder.
I also understand that BPM could have bottlenecks due to queue and cache issues, messages might be pending, or lost etc.
Scenario 2. Asynchronous
1) PI Picks file from a common folder.
2) PI does a data mapping and sends the data to ECC.
3) ECC contains an inbound interface which receives the data and in which abap proxy code is written.
4) ABAP Proxy code executes the same function module and calls a seperate outbound interface and passes the values to it. This would be used in sending the response back.
5) PI receives the response from the second interface and places it in a text/csv file and places it back to another folder.
I would like to know which would be the better approach. Documentation/references to support your claims would be much appreciated.
Cheers,
Mz

Specification for ejb-jar.xml

Hi,
can anyone pls send a link where I can find specification for this xml. A doc that lists the hierarchical relationship of the tags and explains the purpose of each tag.
could not find it on sun's website
thanx n regards

http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtdThis is the DTD for EJB 1.1 specifications. You should atleast refer to 2.0 or 2.1 to make use of the specifications provided by most of the recent app servers.
Here's a link:
http://e-docs.bea.com/wls/docs70/ejb/reference.htmlYou might find a recent one on Weblogic 8.1 documentation.

New to EJB, resources for EJB

hi
i'm new to ejb. can anybody suggest resources or links for learning EJB

1. Get a good book. "Head First EJB" from O'reilly is a good investment.
2. Hand on exercises. Try the Sun's J2EE tutorial.
3. Study the spec.
4. You're expert now.

Remove link for uploaded files in application

Hi all,
I've been following the tutorial on how to upload and download files in application at http://download-uk.oracle.com/docs/cd/B32472_01/doc/appdev.300/b32469/up_dn_files.htm. I have now created my own table which stores the uploaded files and can download them successfully. I would now like to add the ability to delete these files within the application and was wondering what the best way of doing this was?
I would like to add another column to the displayed report with a 'Remove file' link for each listed file, which when clicked would delete the file from the table. I've already tried using a similar method to the one used to upload the files (instead of uploading the file, the called procedure deletes it from the table using the specified ID), but this causes the application to display a blank page when the link is clicked, which I dont want (but does delete the file).
I would appreciate any suggestions.
Regards,
Dave

Dave,
See the login page:
http://htmldb.oracle.com/pls/otn/f?p=31517:101
There are details on how to access the application builder, where you can see how the
setup of that download, delete, upload application has been done.

How to create link for pdf file in discoverer worksheet

Hi All,
I would like to create a link for pdf file into discoverer report (worksheet).
So that i can open linked pdf file using worksheet link.
Can any one tell me about this?
Thanks
Ravi

Hi,
I think the best way to do this is to use a database directory so that you can access your pdf file as a bfile. Then create a mod_plsql procedure that sets the mime type and downloads the pdf file. You then create a calculation in the EUL then returns the URL to your mod_plsql procedure. You can then include this calculation as a hyperlink in your worksheet.
It is not as difficult as it sounds. Please let me know if you need anymore details.

Scheduled Discoverer report link for viewer in portal

Hi,
When a link for scheduled report for plus users is created in portal Oracle suggestes the following. This is good since it does not need the run number and the same link will work for all reruns.
http://<host.domain>:<port>/discoverer/plus?cn=cf_a156&opendbid=SALES_ANALYSIS2&sheetid=42&workbooksource=Scheduled
whereas for opening a scheduled workbook result in viewer the link needs the run number which prevents using the same link for every run.
Do anyone found a way to workaround this
Thanks for the help
Jay

Hi Jay
I can see that you've had this posted for a little while so I thought I would at least let you know that I've read it. I'm afraid the answer is not what you hoped though as I don't know of a way off the top of my head to do what you ask.
Sorry, regards
Michael

Creating a Database link for a user

Hello All,
I am trying to create a database link for one of my users.
When I create it as sysdba the link gets created in the SYS schema which tells me that my syntax is working/fine.
But when I ALTER my SESSION and set my CURRENT_SCHEMA = <USER_NAME> I get ORA-00990: missing or invalid privilege
So I tried granting the user CREATE DATABASE LINK, CREATE PUBLIC DATABASE LINK, and DROP PUBLIC DATABASE LINK.
Same error.
Any ideas what I am missing?
Thanks,
Craig

Here's a good free e-book but without Netbean. It covers everything you would need to know about EJBs.

The question is too vague to be answered. It's a design decision that needs more details.
