How to invoke A CORBA-Java Client Application, from Oracle???

Hi,
I have a CORBA-Java Client Application, which takes the input parameters from a Oracle table and calls the CORBA Server, passes these parameters to the C++ Server Application and gets the results back thorugh CORBA.
My problem is, this java application needs to be invoked, when ever there is a new record in the Oracle table.
I am not sure if i can use Java Stored Procedures in Oracle in this case, because my app is in Sun JVM and i am using BEA WebLogic Enterprise 5.1 for the CORBA.
Is there any other way by which i can invoke this app, when a new record is updated in the Oracle table?
Currently, i have just put a TIMER in my java App, to check the oracle table in every few seconds, to see if there is a new reocrd. If it finds a new record it invokes the corresponding class(corba class), or else just keep sending a messsage that no new record is available.
The problems i am facing in this method are as follows;
1. Unnecessarily, the application has to keep on running if there is no request coming frequently.
2. When there is a new record found, the Corba Class is called and the whole process (till it gets the result back from the server) takes about 20 - 30 secs. But within this period, if there is another record coming into Oracle table, my timer class doesnt invoke another corba class....(though i am using multithreading by using the RemidTask method in the timer.schedule.
(timer.schedule(new RemindTask(),10,5*1000);)
3. Also, if during the first call, there is some error, then the whole process exits, instead of another process running parallely (when a second new record is found).
So how does this timer class act like a multithreading process?
Well, i hope i am not confusing....Please let me know if anyone wants bit more elaboration on this.
It would be really helpful if someone can suggest some answer to my problem.
Thanks in advance.

Thank you very much Keith.
Though i am really getting a hope of solving this problem, from you answer, i am actually not 100% sure if i understood your reply properly.
First of all, about
1. "use the update stored procedure to place the updated record (or unique index) onto an Oracle Application Queue."
-- Why do i need to put the record in the AQ. (Frankly speaking, at this moment i dont have much idea about AQ, probably i can learn more about it from oracle technet site? Or would u suggest anything else?)
Then,
2."Your app then waits on this queue and for each new message, consumes it, gets the data required from the AQ load (e.g the index and or record), and fires off the CORBA class"
-- How does my application stay in the queue? and gets the data from the queue?
Of course, as far as i understand, i am going through the same principle...keeping on running a timer class, which keeps on checking the table for a new record, and when it finds, it calls the CORBA class.
Of course, i feel there should be a difference in running the timer continuosly and staying in queue. However i am totally unaware, how can i make my java app to wait in the queue and waits for a new record?
Can you please elaborate your answer a bit more, because i dont know about the AQ, that you have mentioned.
Thank you very much in advance for your time. But please know that it will be of great help to me and hence will be higly appreciated.

Subhasree.

Help:How can I run the J2EE Client Application? Thanks

Help:How can I run the J2EE Client Application that will access the remote J2EE1.4 application server which runs on another host computer?
I have developped a stateles senterprise java bean name converter and deloyed it in the j2ee1.4 application server on the host machine A. The converterbean provides the remote home interface and remote interface. At the same time I have developped the j2ee application client named convertappclient. When I access the conveter bean at host computer A through the script 'appclient.bat' as 'appclient -client convertappclient.jar', the client can access the bean sucessfully. Now I want to access the bean through the script 'appclient.bat' at host computer B,what files should I copy from host computer A to host computer B;and what the command line should be like? Thanks!
The following are the code of the enterprise java bean and it's home interface .
The client code is also provided.
The enterprise java bean:
package converter;
import java.rmi.RemoteException;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
import java.math.*;
public class ConverterBean implements SessionBean {
BigDecimal yenRate = new BigDecimal("121.6000");
BigDecimal euroRate = new BigDecimal("0.0077");
public ConverterBean() {
public BigDecimal dollarToYen(BigDecimal dollars) {
BigDecimal result = dollars.multiply(yenRate);
return result.setScale(2, BigDecimal.ROUND_UP);
public BigDecimal yenToEuro(BigDecimal yen) {
BigDecimal result = yen.multiply(euroRate);
return result.setScale(2, BigDecimal.ROUND_UP);
public void ejbCreate() {
public void ejbRemove() {
public void ejbActivate() {
public void ejbPassivate() {
public void setSessionContext(SessionContext sc) {
The bean's remote home interface :
package converter;
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
public interface ConverterHome extends EJBHome {
Converter create() throws RemoteException, CreateException;
The bean's remote interface:
package converter;
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
import java.math.*;
public interface Converter extends EJBObject {
public BigDecimal dollarToYen(BigDecimal dollars) throws RemoteException;
public BigDecimal yenToEuro(BigDecimal yen) throws RemoteException;
The j2ee application client:
import converter.Converter;
import converter.ConverterHome;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import java.math.BigDecimal;
public class ConverterClient {
public static void main(String[] args) {
try {
Context initial = new InitialContext();
System.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
System.setProperty("java.naming.provider.url","jnp://10.144.97.250:3700");
Context myEnv = (Context) initial.lookup("java:comp/env");
Object objref = myEnv.lookup("ejb/SimpleConverter");
ConverterHome home =
(ConverterHome) PortableRemoteObject.narrow(objref,
ConverterHome.class);
Converter currencyConverter = home.create();
BigDecimal param = new BigDecimal("100.00");
BigDecimal amount = currencyConverter.dollarToYen(param);
System.out.println(amount);
amount = currencyConverter.yenToEuro(param);
System.out.println(amount);
System.exit(0);
} catch (Exception ex) {
System.err.println("Caught an unexpected exception!");
ex.printStackTrace();
}

Question on "How-to invoke a method once upon application start"

Hello everyone.
I'm trying to implement what the article "How-to invoke a method once upon application start" by Frank suggests.
https://blogs.oracle.com/jdevotnharvest/entry/how_to_invoke_a_method
Suppose that I'm having a single point of entry, so in my login.jpsx I have the below:
<f:view beforePhase="#{login.onBeforePhase}">In the method "onBeforePhase" I have to pass the phaseEvent, since the signature is the following:
public void onBeforePhase(PhaseEvent phaseEvent)but how do I know the phaseEvent when calling the login.onBeforePhase? How the call should be?
Thanks a lot!
ps. I'm using jDev 11.1.2.1.0

You need not pass anything to this method , this method will get called before every Phase except ReStore View
Just write the logic as Frank suggested for the phase in which you want the code to execute. You can get the PhaseId's like
PhaseId.RENDER_RESPONSE
public void onBeforePhase(PhaseEvent phaseEvent) {// from Frank's doc
//render response is called on an initial page request
if(phaseEvent.getPhaseId() == PhaseId.RENDER_RESPONSE){
... etc

How can one develop "view only" client applications in Lookout?This is to develop remote monitoring without control functionality.

How can one develop "view only" client applications in Lookout?This is to develop remote monitoring without control functionality.
We have 10 Client Nodes in the field and we need two "View Only" functionality in Client machines located on Supervisory Desks.

I have done this. There are many ways to approach this but I will offer what I think is the easiest. This will work ONLY if you have been assigning security levels to your objects (objects that actually control devices in the field) greater than zero AND allowing a security level of zero to view all panels. When I develop interfaces I do this just for creating a non control client.
Basically, you remove all users from the Lookout client in the user manager. You will not be able to remove the built-ins, "Guest" and "Administrator". Now when the end users tries to login using his normal login he will be denied. Consequently, he will not be able to control. But, he will still be able to view all the information since a no login can view a panel with a viewing se
curity level of zero. You must ensure any pushbuttons that are used to open panels have a security level of zero.
Now you can copy this security profile by finding the lookout.sec file and copying it to another non-control client computer. In Windows NT this file is located in the system32 directory.
There are many other ways but I find this the easiest.

How to access custom JAVA webdynpro application from an iPad?

Hi,
We are trying to access custom JAVA webdynpro application from an iPad, but nothing is opening up from the iPad browser.
What can be the possible reasons for this? Any kind of SICF enablement or opening up of ports in the network?
Any inputs are welcome!!
TIA,
Regards
Deepthi

Hi,
it is possible to show Java Web Dynpro applications on a mobile device in general, but the controls and the ui should be optimized for the mobile device.
Safari devices are not officially supported so far for Mobile Web Dynpro.
Supported are Windows Mobile devices and Blackberry devices. I also got some good results with Symbian devices.
You can find more inforamtion on Mobile Always Connected at:

Press and hold any of the apps and after a couple of seconds or so they should start to shake. Then press the 'x' in the left corner to delete the ones that you don't want, and when you've finished deleting press the home button so as to stop the shaking. You cannot delete any of the Apple built-in apps e.g. iPod, App Store, Game entre etc. If you don't get the 'x' on any of the apps that you've downloaded then check that Settings > General > Restrictions > Deleting Apps isn't set 'off'
If the app is on your computer's iTunes then you should probably also either delete it from there as well, or un-tick it from your iPad's sync list when you next connect it, otherwise it might get put back on the iPad. As long as the app remains in the app store you can always re-download it for free in the future (http://support.apple.com/kb/HT2519).

How Session/token/Header is passed to Application from OAM ?

Hi Experts,
I have understood that IAM will have obssocookie (10gwebgate), OAM_RMOETE_HEADER (OAM-identity assertor), any thing like session as well ?
Question is
Where is a mapping of enterprise Application session and OAM session ? in other words where we do configuration/assignment of session?
Assumption : Enterprise application is deployed on one weblogic. (application like ADF,WCP,EJB)
IAM is on another weblogic.
Help appreciated

For your qustn: How Session/token/Header is passed to Application from OAM?
1. The appln contain the access code receives user req. for resource
2. AG constructs ObResourceRequest structure
3. The AG constructs ObAuthentication structure (For protected resources)
4. Access server responds and AG constructs ObUserSession struc
5. If credentials true then AG creates a Session Token for the user (this Tokes has usr identity, name of trget requested etc,.)
Thnx

Hi Nicolas!
Have you tried to set "Output Format" for "RAW Text" to HTM in SCOT.
If HTM is missing in your dropdown-list, you could check out table SXCONVERT2. Copy the line with category T/format TXT, and change the format from TXT to HTM. The existing function
SX_OBJECT_CONVERT__T.TXT does not need to be changed. Now you should be able to choose HTM in SCOT. You will probably need som HTML-tags in your text to make it look good.
Hope this helps!
