Can't I invoque an EJB in the Oracle ESB??

Hi all,
I'm just new on Oracle ESB and may be in error, but I have readed that RMI transport is not suported... Is it really true??
What can I do if I want to expose an EJB as a Web Service in the Oracle ESB??
Regards David

I am doing the above quite successfully in a number of ESB processes.
My EJB's are exposed a EJB3 session beans with a web service interface and as mentioned, can be called via a SOAP service.

you can try, but it will not be supported by Oracle Support.

Why can I download and install all of the Oracle ATS products for free?

Why can I download and install all of the Oracle ATS products for free? When I installed, I was not prompted for any licenses or to purchase anything.
I want to know why this is possible and if there are plans to charge for it in the future?

I don't know Oracle's ATS products specifically, but many of Oracle's products can be downloaded and used for free for learning purposes.
Typically, if you intend to use the products commercially then you need to pay for a licence, otherwise you are using it illegally.
This is usually described in the T&C's you agree to when you download the software.

How can I customize a skin starting with the Oracle Skin?

I understand that when customizing skins, you start by over-riding the 'simple' skin.
Where can I find the CSS file for the default oracle skin that I can use as a starting point to jump-start the skin customization? What I am trying to do is customize the skin, but I want to use the CSS for the Oracle skin as a starting point to over-ride the simple skin - I really only need to make a few tweaks to the Oracle skin CSS and don't want to start from scratch with the simple skin.
Any help much appreciated.

ps - all I need to do right now is set up some new styleclasses that I can use to format text-related components. in the future I'd like to be able to format tables - i.e., change format not to display borders, change table heading colors, etc. - is this possible with the 2nd approach based on modifying oracle-desktop.xss?

How to set the oracle oci8 driver?

hello all:
I've set up the oracle thin driver and it works. but when I change to
oci8.it don't work
below is config and errors:
<JDBCConnectionPool DriverName="oracle.jdbc.driver.OracleDriver"
InitialCapacity="5" LoginDelaySeconds="5" MaxCapacity="15"
Name="ocipool"
Properties="user=yanji;password=yanji"
Targets="myserver" URL="jdbc:oracle:oci8:@pg01"/>
Could not load 'oracle.jdbc.driver.OracleDriver
If this is a type-4 JDBC driver, it could occur if the JDBC
driver is not in the system CLASSPATH.
If this is a type-2 JDBC driver, it may also indicate that
the Driver native layers(DBMS client lib or driver DLL)
have not been installed properly on your system
or in your PATH environment variable.
This is most likely caused by one of the following:
1. The native layer SO, SL, or DLL could not be found.
2. The file permissions on the native layer SO, SL, or DLL
have not been set properly.
3. The native layer SO, SL, or DLL exists, but is either
invalid or corrupted.
For more information, read the installation documentation
for your JDBC Driver, available from:

Hello, Jenny I am glad you found your resolution. I too am having problems isung
the oracle 0CI8 driver. My connection pool is creating fine, but my server is
crashing with JVM errors.
Here are my configurations.
DBase=Oracle 8.1.7,OS=Win2000, running 6.1 with Portal 4.0
pool config =

RefreshMinutes="0" Targets="portalServer"
TestTableName="WIP_TABLE" URL="jdbc:oracle:oci8:@servername"/>
My classpath sets my classes12.zip file first. My path sets %WEBLOGIC_HOME%\bin\oci817_8
and %WLCS_ORACLE_HOME%\bin.
Am I setting the right dll and protocol in my .dll? Where can I find documentation
on these properties definitions?

although I put the classes12.zip into the CLASSPATH.but the weblogic.jar
in
front of classes12.zip.so classloader
load the class from weblogic.jar. so I can use thin driver(weblogic
implements this function with class,but not for oci8 )
..this is really a big pitfall !
put the classes12.zip in front of weblogic.jar .all perfect!

Its not CLASS_PATH it should be CLASSPATH.
when you say oracle\bin and oracle\lib , on what driver is the oracle

you have to specify the full path.
post your startup script here.

1. Dont copy this file oci8jdbc.dll, to bin folder. Make sure
you
place
<oracle_home>\lib in your PATH before starting the server. Make
sure
your
ORACLE_HOME environment varable is set to <oracle_home> folder.
eg. set ORACLE_HOME=c:\ora816 before starting the server.
so you must have done something like
set ORACLE_HOME=c:\ora816
set PATH=%ORACLE_HOME%\bin;%ORACLE_HOME%\lib;%PATH%
2. double check if you set your CLASSPATH something like this,
CLASSPATH=%ORACLE_HOME%\jdbc\lib\classes12.zip;%CLASSPATH%
in the server startup script just before starting the server.
3. start the server the connection pool should work.

I've edited the StartWeblogic.cmd, set the classes.zip into CLASSPATH,and
copied the oci8jdbc.dll to the bea\wlserver6.1\bin. errors stillappears!
my weblogic version is 6.1 and oracle is 8.1.6 .
why the thin driver is ok but the oci driver can not work?
I logined in the oracle website and look for the jdbc.but I find
that
jdbc
all provide for jdk1.2 or jdk1.1. because the weblogic6.1 based
jdk1.3.
I
think i can not use those drivers.
I think my oracle driver is ok,because i installed the jboss and
bas4.5
in
my computer. they all can use oci8 driver properly.and they all
based
jdk1.3.
by the way. I 've tryed added the oracle\bin path inStartWeblogic.cmd,
nothing changed !
again below is my config : I want to know whether my config right?
(the property DLL and Protocal auto added by the weblogic)

To use oracle oci8 driver:
You should have classes12.zip in weblogic classpath.
You should have ocijdbc8.dll in your weblogic path..
You can download ocijdbc8.dll from oracle website.

What are the Oracle Grid's differences or strengths against other vendors

Hi,
I'd like to know what Oracle 10g system is different from others.
There are many concepts for Grid computing,
but isn't still standardized form for it.
So many vendors are imprementing their own Grid system.
Can anyone point out about what are the Oracle Grid's differences or strengths against other vendors (IBM, Microsoft, Sun etc)
Thank you.

Hi
I'm very skeptical about what Oracle calls grid computing. Few years ago I wrote a paper entitled "Is Oracle Database Moving Toward Grid Computing?" (http://www.trivadis.com/Images/grid_computing_en_tcm17-11759.pdf) handling that topic. Honestly, even two releases later (10.2 and 11.1) things has not really changed.

Can I call an EJB from the database?

Hi,
I've just spent the last few days attempting to call an EJB from a stored procedure in a 10g database (and still haven't succeeded).
Now having spent hours searching the web (and this forum) for any successful examples (so far I have found none) I thought I'd add a message to see if there is anybody out there who has done this successfully. If so can you please provide me some details on how to do this?
Alternatively, I'd appreciate any input on how I can overcome my current hurdle in attempting to do this myself.
Here's how far I've got in my attempt:
I have a simple stateless session bean deployed to both Oracle 10gAS (a standalone OC4J container in 10.1.3) and to Weblogic 9. I have a client java class that calls a method on this bean and displays some ouput if successful. This all works from a standalone JVM (version 1.4) on both Weblogic and 10gAS.
I then tried to load the required libraries for Weblogic onto the database (namely the Weblogic.jar file). This resulted in the addition of some 32,000 odd objects of which 30,000 odd could not be resolved. I figured a lot of these may be down to JVM version issues (I believe that Weblogic 9 uses the 1.5 JRE) so I decided to put the Weblogic test on the back burner for now and just use the Oracle app server.
The tests with the Oracle app server looked promising. I only needed a handful of libraries to be loaded onto the database and all the relevant classes required for my test client had resolved (including the initial context factory required to do the jndi lookup of the bean). After granting all the permissions I believed I needed I'd got to the point where I could do a jndi lookup of the EJB; but when I tried to create an instance of the beans remote interface I got the following error:
java.security.AccessControlException: the Permission (java.lang.RuntimePermission getClassLoader) has not been granted to ProtectionDomain (file:generated/by/proxy <no certificates>)

Has anybody come across this before? If so can they help?
If not has anybody out there actually managed to call an EJB method (without going via an RMI server/Servlet/or any other proxy).
Any help in this matter would be greatfully appreciated.
Cheers,
Anand.

Sure, here's the code. It's what JDev generates automatically but I have seperated some things into several diffrent lines so I could experiment easier.
final Context context = getInitialContext();
Object o=context.lookup( "SessionEJB4" );
Object l= PortableRemoteObject.narrow( o, SessionEJB4Home.class );
final SessionEJB4Home sessionEJB4Home = (SessionEJB4Home)l;
SessionEJB4 sessionEJB4 = sessionEJB4Home.create();
String ret=( sessionEJB4.hello( ) );
As I mentioned, for this I have used EJB2.1 bean, because I had same problems with EJB3.0, so I tried earlier versions of Java to make sure that is not the problem.
hello() method just returns string "hello".
Of course, this works in standalone client that is not loaded into database.
Now, I loaded all the jars mentioned in this thread, using loadjava options -v -resolve, and I loaded client using options -v -resolve -genmissing . Select query on user objects in database shows that client class and relevant classes are all valid.
Then I created stub and ran it. First it stopped throwing exception ORA-29532: Java call terminated by uncought Java exception: Java.lang.NoClassDefFoundError.
Method I try to run returns String value which is hello message if it works fine, else it prints the part of the stack trace. In this case, after p[revious error, When I try to run it again, i get return from the method :
Lookup error: java.lang.NoClassDefFoundError; nested exception is:

Of course, regular version of the client I run frokm command line works fine.
So I'm kind of a stuck here. I followed all directions, tried it on oracle 9 and oracle 10 DB, the problems remain the same. Am I missing something here?
Thanks
Just to add, getInitialContext()
    private static Context getInitialContext() throws NamingException {
        Hashtable env = new Hashtable();
        // Oracle Application Server 10g connection details
        env.put( Context.INITIAL_CONTEXT_FACTORY, "oracle.j2ee.rmi.RMIInitialContextFactory" );
        env.put( Context.SECURITY_PRINCIPAL, "oc4jadmin" );
        env.put( Context.SECURITY_CREDENTIALS, "manager1" );
        env.put(Context.PROVIDER_URL, "opmn:ormi://mserv:4005:home/TestEjb4");
        return new InitialContext( env );
It goes withouth any exceptions.

Where can I find the deployed EJB files in Oracle 10g AS(904)

Hello All,
Where can I find the deployed ejb files, stubs and skels in the Oracle 10g (904)
When I try to run my ejb application I m getting following exception:
com.evermind.server.rmi.OrionRemoteException: Error (de-)serializing object: org.apache.log4j.Logger
I am not sure what is causing this error. I am not using any logging in my EJB. But the logging framework is configured in the application server.
Your input would be a great help to me
Thank you

Thanks Carty,
I am not creating Connection from EJB. I have a POJO called DBManager that looks for the DB Connection and return that to either EJB or other POJO that requests for Connection.
I am having a private method that get the connection from the DBManager because while writing UnitTest cases I can mockup getting Connection as my Unit test case will be a POJO again..
I have a question here regarding making DBManager as Singleton class. In my current project, I have configured my database in the application server as getting the connection by lookup for datasource through JNDI. It internally maintains all logical connection and always have one physical connection. In such scenario how implementing singleton will be beneficial?
Thank you for answering all my questions.

How can I deploy the EJB to the remote AP Server

Dear All,
Any one know how can I deploy an EJB to the AP server which is not located on the local machine, using Jdev9.0.3.1.
I have try to new a connection with the server name and the testing connection section is successful, however when I deploy the EJB to that connection the error comes out as following:

Thank you very much!!

Your question is a bit unclear.
If you are referring to converting from using JInitiator to JRE, pl see MOS Doc 290807.1 (Deploying Sun JRE (Native Plug-in) for Windows Clients in Oracle E-Business Suite 11i).
If you are referring to upgrading Java versions for use by EBS, pl see MOS Doc 401561.1 (Using J2SE Version 6 with Oracle E-Business Suite 11i).
MOS Doc 300482.1 (Overview of Using Java with Oracle E-Business Suite Release 11i) gives an overview of Java usage with 11i.

pls help me..........

h.put(Context.INITIAL_CONTEXT_FACTORY," ********what should i use here???????*************************")
Each app server provides their own jndi factory class. For ex for weblogic it is weblogic.jndi.WLInitialContextFactory. SInce you are using sun app server, check if there are any examples to find out or the docs.
private static String url="http://localhost:4848
Since the client is in a different machine the localhost is not going to work here. provide the url or the machine name of the system in which ur sunapp server is running. In addition u will need to have the stubs of the remote interfaces in ur client machine.

Deployment error: The Entity EJB requires the table: to be accessible

When I deploy my EJBs, WEBLogic throws an exception:

Hi Maris,
I see that you have create-default-dbms-tables set to true so WLS should be creating
the database table for your EJB. If you can give me some more information, I'll be
able to help you further. What version of WLS + service pack are you using? Also,
is this a 1.1 bean or 2.0? Lastly, what are the types of the CMP fields in your
bean?
As a work-around, you can try creating the database table yourself before deploying
the bean. This should resolve the deployment problem.
