J2EE Application for OAS10g Release 3

Dear All
If anyone of you have any j2ee application for OAS10G Release 3 .Please send to this id [email protected] .

If you have to choose an architecture now, I would advice not to choose Oracle Application Server, but BEA WebLogic. On Oracle Open World I learned that Oracle will stop developing on OC4J, so WebLogic seems the smarter choise.
To either choose weblogic or websphere has to do with a lot more then just the J2EE specs. It also has to do with knowledge of your collegues (who have to support either of these products), company strategy, etc. Therefore this question cannot be answered that easy.
Personally I think an all Oracle stack is just fine, WebLogic has a richer featureset then WebSphere (AFAIK). WebSphere is not a bad product though.

J2EE APPLICATION ON OAS10G AND J2EE APPLICATION ON IBM Websphere

Hi All,
As you all know that there are many application servers in the market for deploying the application so I just want to know why we all choose Oracle Application Server 10g for deploying J2ee application and why some choose IBM Websphere for deploying J2ee application. Is there any doc which specifies that Deployng J2ee application on Websphere is better than OAS 10g.

Emails Architecture for big J2EE Applications

Hi all !
Need some inputs regarding design of email sending mechanism in huge J2EE applications.
We are having a medium based application (say 2 lakh subscibers) but may have a increase in
subsciber base sooner. Its a 3-tier application using Struts (JSP), EJB & Database is Oracle 8i.
Till now we are using Oracle jobs for submitting emails (asynchronus), it works fine for small subscriber
base but increase in subscriber base will increase load on database and we want to avoid that.
Concerned points are :
1. What architecture is followed in big J2EE applications for sending emails asynchronously ?
2. How much feasible is using JMS provided with weblogic app server for huge applications ?
3. Does using messaging queues at app server end will degrade performance considerably ?
Please see if anyone can help out in this..
Puneet Gandhi

I've used JMS + Weblogic (2 quad processor servers in cluster) and JMS in a system that took between 5,000 & 10,000 new users per day. It held up fine.
I'm not an architect (more of a developer), but I would create a serializable NotificationBean, send it to a MessageBean, and let the MessageBean send the email. Providing your queues are persisting and that you limit the number of MessageBeans to something reasonable, I don't see why you should have performance problems.
Alternatively if you use MQ I believe it has an email node that you can send messages to. Don't know much about this though.

J2EE Application doesn't work in EP6

Hi there, I'm a contractor who is building a J2EE application for deployment onto an SAP EP 6 server.
The server is running Windows Server 2003, and the installation of EP 6 is a fresh, clean install with nothing significant done to it.
I have installed NW DS on my computer, developed and compiled the application on my computer (using Apache) and everything ran successfully. Now, when I try to deploy it to the EP 6 server I get "Resource not found" at every possible turn. The documentation provided is woefully incomplete and ambiguous. This should have been a simple project, but I've killed an entire week switching my development platforms to SAP and rewriting the application and nothing seems to work on the server. Please help me.

Hi Brian,
first thing that makes me suspicious: You develop with NW DS and deploy from there to Apache??? How do you do that?
And if, deployment to EP for sure does not work the same way!
What kind of app are you developing?

Benny

Best practice for distributing/releasing J2EE applications.

Hi All,
We are developing a J2EE application and would like some information on the best
practices to be followed for distributing/releasing J2EE applications, in general.
In particular, the dilemma we have is centered around the generation of stub, skeleton
and additional classes for the application.
Most App. Servers can generate the required classes while deploying the EJBs in the
application i.e. at install time. While some ( BEA Weblogic and IBM Websphere are
two that we are aware of ) allow these classes to be generated before the installation
time and the .ear file containing the additional classes is the one that is uploaded.
For instance, say we have assembled the application "myapp.ear" . There are two ways
in which the classes can be generated. The first is using 'ejbc' ( assume we are
using BEA Weblogic ), which generates the stub, skeleton and additional classes for
the application and returns the file, say, "Deployable_myapp.ear" containing all
the necessary classes and files. This file is the one that is then installed. The
other option is to install the file "myapp.ear" and let the Weblogic App. server
itself, generate the required classes at the installation time.
If the first way, of 'pre-generating' the stubs is followed, does it require us to
separately generate the stubs for each versions of the App. Server that we support
? i.e. if we generate a deployable file having the required classes using the 'ejbc'
of Weblogic Ver5.1, can the same file be installed on Weblogic Ver6.1 or do we
have to generate a separate file?
If the second method, of 'install-time-generation' of stubs is used, what is the
nature/magnitude of the risk that we are taking in terms of the failure of the installation
Any links to useful resources as well as comments/suggestions will be appreciated.
TIA

Aasif

Its much easier to distribute schema/data from an older version to a newer one than the other way around. Nearly all SQL Server deployment features supports database version upgrade, and these include the "Copy Database" wizard, BACKUP/RESTORE,
detach/attach, script generation, Microsoft Sync framework, and a few others.
EVEN if you just want to distribute schemas, you may want to distribute the entire database, and then truncate the tables to purge data.
Backing up and restoring your database is by far the most RELIABLE method of distributing it, but it may not be pratical in some cases because you'll need to generate a new backup every time a schema change occurs, but not if you already have an automated
backup/maintenance routine in your environment.
As an alternative, you can Copy Database functionality in SSMS, although it may present itself unstable in some situations, specially if you are distributing across multiple subnets and/or domains. It will also require you to purge data if/when applicable.
Another option is to detach your database, copy its files, and then attach them in both the source and destination instances. It will generate downtime for your detached databases, so there are better methods for distribution available.
And then there is the previously mentioned method of generating scripts for schema, and then using an INSERT statement or the import data wizard available in SSMS (which is very practical and implements a SSIS package internally that can be saved for repeated
executions). Works fine, not as practical as the other options, but is the best way for distributing databases when their version is being downgraded.
With all this said, there is no "best practice" for this. There are multiple features, each offering their own advantages and downfalls which allow them to align to different business requirements.

Is anyone doing disaster recovery for a J2EE application?

We generally use database log shipping to maintain a standby database for our ABAP instances. We can successfully fail over our production application to our disaster recovery site with no real issues. With the J2EE instances (EP, ESS/MSS, BI, etc), we have a few concerns:
hostname cannot change, without going through a system copy procedure, so we would have to keep the hostnames in DR the same. (for example, ref: oss note 757692 - changing hostname is not supported)
fully qualified domain name - from what I understand, there are potentially issues with changing the fqdn, for example SSO certificates, BSPs, XI has issues, etc.
we can't keep both hostname and fqdn the same between DR and production, or we could never do a DR test.
Has anyone implemented disaster recovery for any SAP J2EE application that has run into these concerns and addressed them? Input would be greatly appreciated regarding how you addressed these issues, or how you architected your disaster recovery implementation.
Regards,
David Hull
The Walt Disney Company

I haven't done this personally, but I do have some experience with these issues in different HA environments.
To your first point: You can change the hostname, note 757692 tells you exactly how to do it. However like the note says, "Changing the name of a host server in a production system is not automatically supported by SAP." When it says "supported by SAP" I think it means SAP the company, not SAP's software. So I would contact SAP to see if this configuration would be covered under your service agreement. Then you have to think about whether you want to do something that isn't "officially supported" by SAP. Also I'm sure you'll need some kind of additional licensing for the DR systems as their hardware keys will de different.
To your second point: As for SSO certs (SAP Login Tickets), I think they should still work as long as the SID and client number of the issuing system remain the same. I don't think they are hostname or fqdn dependant. For BSPs I would think they would still work as long as they use relative paths rather than absolute paths. And for XI... I have no idea what kind of issues may arise, I'm not an XI guy.
Again, I haven't done what you're describing myself. This is just based on my HA experiences.
Hope this helps a little,
Glenn

Portal User details and credentials for a J2EE application?

Hi,
I am trying to access a J2EE application which is deployed in SAP Web Application Server. I want to maintain the security of this application depending the portal user. So I want to get the user id of the portal login to my J2EE application. For Example:
A user with id "super" is logging into portal I want the userid "super" in my J2EE application how to get the userid to my J2EE application's servlet. Is this possible? If possible please tell how I can acheive it?
Can I do it by creating HTTP System? If possible can u tell me where can I set the URL?
Thanks,
Ashok.

hi,
Certainly you can get the user id of the portal login in your J2EE application by using UME api's
IUserFactory userFact = UMFactory.getUserFactory();
getUserFactory().getUser(String uniqueID)
getUserFactory().getUserByLogonID(String logonID)
Also have a look at this
http://help.sap.com/saphelp_nw04/helpdata/en/15/abdc3ed98f7650e10000000a114084/frameset.htm
Instead of url iview, it would be better to use AppIntegrator
Also have a look at this

J2EE Filter for /irj application

Hi,
i developed a J2EE Filter for irj application but i am getting some problem:
1) The irj application cannot load the J2EE Filter; it throws a ClassNotFoundException. I think that the problem is linked with a
    ClassPath/ClassLoader issue.
2) I don't know the session attribute name that stores the URL alias used by a user during logon step. I have to set up to null
     this attribute in order to obtain a recomputation of the portal desktop to show when a user change application using
     different alias.
These are the steps:
1) I made a jar file for the filter linked to a .sda file through NWDS.
2) I deployed this sda file throug NWDS
3) I changed the web.xml to configure the new filter component
4) restart the server but not worked.
Can anyone help me please?
Carlo Paglia

Hi,
the file is correctly located in the dir that you suggested. Opening Visual Administration tool i can see the entry "EnteprisePortalFilterLibrary" in the Libraries section linked with the jar name.
Restarting the server i obtain again ClassNotFoundException. I think that the problem is correlated to the server ClassPath but i don't know how to configure it.
Have you got other suggestions?
Kind regards,
Carlo Paglia

10.1.0.5 Patch for Oracle Application Server 10g Release 1

Hi Guys,
Does anyone know what is the patch number for 10.1.0.5 Patch for Oracle Application Server 10g Release 1?
This is a Oracle Application Server and not Oracle Database server.
I tried searching on Metalink but not able to find it.
Thanks in advance!
Avinash.

10.1.0.5 is not a version number for an OAS. It is only a version number for RDBMS.
If you are running OAS 10.1.2.x with the Identity Managmenet/SSO (OID Server), & elected to have it install the Metadata Repository database for you, this was a RDBMS release below 10.1.0.5. The OAS patch to 10.1.2.2 or 10.1.2.3 required the RDMBS be updated to 10.1.0.5 first. This is the standard 10.1.0.5 update for your platform.
use Advanced Search on Metalink
To find the OAS 10.1.2.2 or 10.1.2.3 patch set, search for Oracle Fusion Middleware Server. Release 10.1.2.2 and 10.1.2.3. Look for the decriptions like "PLACEHOLDER BUG FOR AS/DS 10.1.2.3 PATCHSET RELEASE" OR "PLACEHOLDER BUG FOR AS/DS 10G R2 PATCH SET 2 10.1.2.2"
To find the RDBMS 10.1.0.5 patch, search for RDBMS Server, Release 10.1.0.5. Look for the Description containing something like "10.1.0.5 PATCH SET FOR ORACLE DATABASE SERVER"
The patch number is different per platform, so I can't tell you the exact #s without more info (OS)

Unit test for J2EE application

I am writting a Unit test for One J2EE application. The Application is built in such a way that makes unit testing extremely difficult.
There are 2 things that contribute to the mess.
1. Sping integration means all the config files are specified in web.xml independently, even though their beans rely on each other across files. End result is in a unit, I cannot try to load a bean because some of its dependencies are missing (ie. they are in a config file that the first file does not include). For this I tried to use AbstractDependencyInjectionSpringContextTests class to set the Spring Application Context when you are not in the flow but didn't success ed.If any one has use this please post the example.
2. The application is using Errors interface of package org.springframework.validation. To write a test for any validator class you have to pass the object of Error in the validate method with the command object. Now my question is how you can set this Error object when you are not in the flow. For this I tried to use Mock object e.g Errors error;
Mockery context = new Mockery();
final Errors errorMock =context.mock(Errors.class);
//call the validate object with mock object
classObject.doValidate(cmdObject, errorMock)
This thing doesn't work. It gives me below error message.
unexpected invocation: errors.pushNestedPath("")
no expectations specified: did you...
- forget to start an expectation with a cardinality clause?
- call a mocked method to specify the parameter of an expectation?
Is there any way to get around these hiccups programmatically in unit tests?
thanks...

If you are doing unit testing, try to use straight JUnit4 without involving the Spring framework. Given that you do unit testing, you might not need Spring configuration in your unit test at all. You can programmatically instantiate the instance of the class under testing and either programmatically instantiate collaborating objects, or create mock objects for that purpose. If you are doing functional testing, you might need a Spring context after all. Understand that your tests are running in the different context than the complete application, so you would have to create separate application context for your test(s). You might have to go through the existing Spring configuration modules that you created for your application and re-jiggle them a bit so that they can be included both in your application context and your unit test context.
Hope this helps.

BI applications for EBS R12 release in OBIA 7963 release

Hi all,
Can anybody list the BI applications for EBS R12 release which supported in OBIA 7.9.6.3?
Thanks
Ram

Are you referring to the EBS functional modules? BI Apps has a numbe of product families (Financial Analytics, HR Analytics, CRM Analytics..etc) that can source from EBS as well as other ERP systems (PeopleSoft, Siebel, JDEdwards..etc). If you are looking for the functional areas, I would suggest asking your Oracle rep for the "Product Guides" for the package you need (e.g Financial Analytics, HR Analytics..etc). Also there is a "Content Guide" you can find on metalink that lists the OOTB reports, dashboards, and Metadata content (RPD attributes).
Here is the list of DAC subject areas under the vanilla EBS container..it may help for now until you have the other docs:
