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.

Add new translated language resources for ADF components

Hello
I wish to add a new language for the ADF components.
Our product was translated in serbian language but some items like Next, Previous buttons or the OK and Cancel buttons in the popup dialogs of type OkCancel uses build-in resources of the ADF and does not provide the translation for all languages.
How is it possible to extend the resources of the ADF with any other language?
I see the old thread Re: ADF component language for the Georgian language.
And I guess there are more languages required by some customers.
Is there any solution available by the ADF how we can just provide the missed translations and configure ADF to load them?
Kind Regards
Paul Daratha

Hi,
you can bind the text of the components with your bundle.
see the doc:
http://docs.oracle.com/cd/E23943_01/web.1111/b31973/af_global.htm#CHDGCAFI
and here are a resource strings for components
http://docs.oracle.com/cd/E24382_01/apirefs.1112/e17497/toc.htm
As far as I know yo can´t add a language.

KM Resource for Super User to add attributes

System: BI Portal, 7.0
I want to create a resource for my super users to add description data to a report, but I don't want the other users to be able to see that control on their screens. In other words I don't want them to attempt to add description data and get a "permission error", they should not see the control.
Currently all of my controls on the iview's resources are read only. In the KM content directory the "super users" can add reports to the specific directories that they have permission for.
How is that done?
Do I have to create another iview with specific editing resources on it for the super users?
Thanks,
Mike

I'll create a new role and resources for users to make adjustments.

New to EJB (Server Help Needed)

I am new to EJB and I'm learning through a few books and online tutorials. The only problem is that when I try to use them, I get errors. I've done some researching and I think it has to do with my server setup. Here is what I have running and successfully configured:
Apache Web Server
Tomcat Container
Java 2 SDK 1.4.0_01
Java XML Pack (Winter 2002)
I have Sun Studio 4 installed and I think that it installs J2EE but I'm not sure. Can someone help me understand where to go next? What do I have to install/configure to get the EJBs to work? Thanks, Jeremy

Hello,
J2EE is roughly about two things: Web applications beeing build out of Servlets, Jsp and HTML pages and a server-side component modell to deploy business logic in EJBs.
Now for the Web part (generating dynamic HTML content etc.) you have what you need. Tomcat is doing just find. To deploy EJBs, you need an application server which has an EJB container. I don't know the Studio 4 but my understanding is that it is an IDE helping you to develop software, not an application server. You have to install such an appserver.
My recommendation: go and download BEAs Weblogic 7.0 (www.beasys.com).This is a commercial product but it comes with a 30 day trial license. BEA provides a rather good online docu. Play with this appserver and deploy some EJBs.
Alternatively there is also a free appserver: JBoss (www.jboss.org) but I have never used it. Yet, they have also online docu and forums to help you through.
good luck,
einar

i put all the remote,home and local interfaces in a package and added that package to a jar file.
then i added the jar file to class path.
import this package into your client class.
thats it now just deploy your ejbmodule.jar and webapplication.war in the server and test the code
bye bye

Error encountered while polling the resource for the service endpoint

Hello everyone
I'm a newbie on OSB world. Yesterday, I've tried to test OSB with FTP transport and got some problems.
As you see in the title, I've search this forum to get a solution already, but I couldn't find anything. So that I create a new thread.
I created a new OSB project, create a new Proxy service to connect to my FTP server:
- service type: messaging service
- request message type: Text, response message type: None
- FTP transport: external user (I used a Service account), Post read action: archive, transfer mode: ascii, some directories needed were created in /tmp directory
- Message flow: Start node -> pipeline pairs
in request pipeline of pipeline pairs node: i created a new stage: Assign action -> Log (to get file contents, error severity) -> Assign -> Log (get file name)
The expected results are: file file content and file name (display in osb console) after I submit a text file to ftp server (using test console or ftp client)
But, some error occur continuously after I submit a text file (I can get the file content because error raise and log catch it). The error message is show below:
<Jun 6, 2011 10:04:59 AM EDT> <Error> <ALSB Logging> <BEA-000000> < [PipelinePairNode1, PipelinePairNode1_request, show_text_info, REQUEST] file contents: li

How can we suggest a new DBA OCE certification for very large databases?

How can we suggest a new DBA OCE certification for very large databases?
What web site, or what phone number can we call to suggest creating a VLDB OCE certification.
The largest databases that I have ever worked with barely over 1 Trillion Bytes.
Some people told me that the results of being a DBA totally change when you have a VERY LARGE DATABASE.
I could guess that maybe some of the following topics of how to configure might be on it,
* Partitioning
* parallel
* bigger block size - DSS vs OLTP
* etc
Where could I send in a recommendation?
Thanks Roger

New Host Adapter plugin for Illustrator CC 2014?

I'm seeing that the Host Adapter plugin for Illustrator CC does not work for Illustrator CC 2014. I've checked that the AIHostAdapater.aip file is installed in the correct AI CC 2014 folder. But calling AIEventAdapater.getInstance().pingPlugIn() always results in "pingTimedOut".
Is there a new AIHostAdapater plugin forthcoming for Illustrator CC 2014? Or is it available somewhere to download? It is not available as an update through Extension Builder.

Hi Brian,
You can download the CC2014 host adapter plugins for Illustrator from the following URL
https://github.com/timothybrandspencer/CEP-Resources/tree/master/host_adapters/illustrator
Worked for me(verified of 64 bit installation of Illustrator on WIN and MAC), hope it works for you as well

Schedule parallel activities on different resources for the same period

Hi,
I am trying to create a PPM where I need to define parallel activities on different resources for the same time period.
For example:
Input prod: P1
Output prod: O1
Now I define a dummy activity A1 to define this consumption i.e. 1 PC of P1 gives 1 PC of O1.
Now I have got 3 resources R1, R2, R3.
I define 3 activities A2, A3, A4 for these resources.
Now I have to arrange activities A2, A3, A4 such that they start simultaneouly after activity A1 and also end simultaneouly.
The Fixed duration for all the resources is 1 week.
My requirement is that out of these resources system should plan for demand considering the resource with minimum capacity
i.e. kind of bottleneck resource.
I am using CTM engine for planning.
I have defined A1 as predecessor for all the 3 activities A2, A3, A4 and after completion all the activities have a dummy successor activity S.
But this setting is not working and PPM is not getting exploded, If I use a normal linear relationship between activities it works fine but my requirement is not getting satisfied.
Can anyone please help me in this case or suggest some alternate method.
Thanks & Regards,
Sanjog Mishrikotkar

Hi,
You cannot use the old solman key as systems are on different server.

Announcing 3 new Data Loader resources

There are three new Data Loader resources available to customers and partners.
•     Command Line Basics for Oracle Data Loader On Demand (for Windows) - This two-page guide (PDF) shows command line functions specifc to Data Loader.
•     Writing a Properties File to Import Accounts - This 6-minute Webinar shows you how to write a properties file to import accounts using the Data Loader client. You'll also learn how to use the properties file to store parameters, and to use the command line to reference the properties file, thereby creating a reusable library of files to import or overwrite numerous record types.
•     Writing a Batch File to Schedule a Contact Import - This 7-minute Webinar shows you how to write a batch file to schedule a contact import using the Data Loader client. You'll also learn how to reference the properties file.
You can find these on the Data Import Resources page, on the Training and Support Center.
•     Click the Learn More tab> Popular Resources> What's New> Data Import Resources
or
•     Simply search for "data import resources".
You can also find the Data Import Resources page on My Oracle Support (ID 1085694.1).

Unfortunately, I don't believe that approach will work.
We use a similar mechanism for some loads (using the bulk loader instead of web services) for the objects that have a large qty of daily records).
There is a technique (though messy) that works fine. Since Oracle does not allow the "queueing up" of objects of the same type (you have to wait for "account" to finish before you load the next "account" file), you can monitor the .LOG file to get the SBL 0363 error (which means you can submit another file yet (typically meaning one already exists).
By monitoring for this error code in the log, you can sleep your process, then try again in a preset amount of time.
We use this allow for an UPDATE, followed by an INSERT on the account... and then a similar technique so "dependent" objects have to wait for the prime object to finish processing.
PS... Normal windows .BAT scripts aren't sophisticated enough to handle this. I would recommend either Windows POWERSHELL or C/Korn/Borne shell scripts in Unix.
I hope that helps some.

"Missing signed entry in resource" for only some users

Hi,
I have recently updated my .jnlp file and .jar file and added some extra jar resources in the new jnlp.
Since this new version, some users receive an error saying
"Missing signed entry in resource:" for one particular resource.
While for other users it works fine.
I have signed the jar with jarsigner.
Does anyone have an idea what could be the problem here?
Thanks very much in advance,
Best regards,
Stein Aerts,
University of Leuven, Belgium

I remember hearing something like this, and had to do with :
1.) what version of jarsigner was used to sign the jar, and
2.) what version of JRE was used to validate the signed jar file on the client.
(including US only vs. International version of JRE)
For the jar that gets this error:
Does it have any empty directories in it., or does it have entries with non-english characters in the resource names ?
What version of the JDK was used to run jarsigner to sign this jar, and what jre is the application running on ?
