J2ee naming services and Oracle 9iAS

I am trying to use the JNDI services of the j2ee specs with JDeveloper and the Oracle Application server (9iAs). Doing this we have the problem that JDeveloper do not support the java.naming package. We have added the package to JDeveloper but we do not know ik Oracle 9iAs will work with this package added.
Can someone give me some information about the use of JNDI within JDeveloper and Oracle 9iAs

About Oracle Heterogeneous Services and Oracle Gateway

Hi All,
I am very new at this topic, I want to know:
1)Oracle Heterogeneous Services and Oracle Gateway same or not?Need license or not?
2)If want Creating Database Link from Oracle 11g to Sybase AS 15.5 Using Oracle Heterogeneous Services what drivers should I install from my pc(windows 7) and from my server(Linux red hat 5)?please give me link for this
3)Is there any link Step by step to configure odbc until creating dblink?
4)what more convenient, connect sybase from Oracle Heterogeneous Services or Oracle Gateway?
Thank you so much for your help
Regards
JOE

Joe,
let copy/paste your questions and comment inline:
1)Oracle Heterogeneous Services and Oracle Gateway same or not?Need license or not?
Let me first clarify one thing, heterogeneous services is the generic mechanism in the Oracle database used by all gateways. The product you are talking about is the Database Gateway for ODBC or the Database Gateway for Sybase.
The Database Gateway for ODBC is available for Linux and Windows. It is the free product which does not require an Oracle license. The license is included in your database license. It is a generic gateway which allows you to connect with any suitable 3rd party ODBC driver to a matching foreign database. As it is a generic connectivity which aloows you to connect to real databases but also to MS Excel or even Text files as long as you have a suitable ODBC driver, its capability is very limited.
The more powerful gateway is the Database Gateway for Sybase. It covers the same functionality as DG4ODBC but it allows you also to work with distributed transactions, it allows you to call remote Sybase stored procedures etc. This gateway is design for Sybase ASE connections, so it is also able to map certain Oracle functions to Sybase equivalents. This Database Gateway for Sybase is NOT for free, it requires an additional license.
2)If want Creating Database Link from Oracle 11g to Sybase AS 15.5 Using Oracle Heterogeneous Services what drivers should I install from my pc(windows 7) and from my server(Linux red hat 5)?please give me link for this
That depends on your preferences. Both gateways are available for Linux and for Windows. When using DG4ODBC you only need to pay attention that you get a suitable 3rd party ODBC driver for this platform with the matching word size (64bit for 64bit DG4ODBC and 32bit ODBC driver for installations of DG4ODBC on 32bit platforms).
The latest software release is currently 11.2.0.3 and it can be downloaded (and installed from scratch) from "My Oracle Support". Just open the Patches & Updates section, look for Patch 10404530: 11.2.0.3.0 PATCH SET FOR ORACLE DATABASE SERVER and make sure to choose the platform you want to use. Then check out the readme as it lists which of these download CD's contains the gateway software.
BTW, the CD contains DG4ODBC and DG4SYBS and it is up to you to decide during the installation which product you want to use.
3)Is there any link Step by step to configure odbc until creating dblink?
The ODBC driver installation differs from vendor to vendor and platform to platform - so we don't have a specific note how to configure the ODBC driver. This kind of question is better handled by the ODBC driver vendor.
Regarding the set up of DG4ODBC on Windows you find suitable information in the knowledge base on My Oracle Support. Just look for:
How to Configure DG4ODBC (Oracle Database Gateway for ODBC) on Windows 32bit to Connect to Non-Oracle Databases Post Install          [Document 466225.1]
and for DG4SYBS:
How to Configure DG4SYBS (Oracle Database Gateway for Sybase) on 64bit Unix (Linux, AIX, HP-UX Itanium and Solaris) Post Install          [Document 437696.1]
How to Setup DG4SYBS (Database Gateway for Sybase) on a 64bit Windows          [Document 1319852.1]
4)what more convenient, connect sybase from Oracle Heterogeneous Services or Oracle Gateway?
It really depends on your needs. DG4SYBS is surly easier to install as this gateway comes with everything you need and you do not have to find a suitable ODBC driver nor get the ODBC driver working. It is also more powerful as you can for example use triggers that replicate data changes in an Oracle database to the Sybase database within the same transaction. When you want to call Sybase stored procedures you can also do that with DG4SYBS. So it really depends on your needs.

How to istall oracle forms service and oracle reports service and testing

How to istall oracle forms service and oracle reports service ?
and we can make test?

How to istall oracle forms service and oracle reports service ?http://download.oracle.com/docs/cd/B19375_07/doc/frs/docs.htm
and we can make test?Once installed, there is a test program both for Forms and Reports... or you mean something else ? if so, please clarify.

Can Oracle9i and Oracle 9iAS co-exist on same machine.

I was wondering if Oracle9i and Oracle 9iAS can co-exist on same machine. I like to play around with 9iAS and I already have 9i database up and running on this one box.
Thanks.

What issue are you having? You can install both versions of Forms into separate homes. You then have two versions of your Forms application, in different directories. Then your FORMS60_PATH points to your Forms 6i forms, and your FORMS90_PATH points to your Oracle9i Forms forms. There is no conflict.

J2ee naming services with JDeveloper

I am trying to use the JNDI services of the j2ee specs with JDeveloper and the Oracle Application server (9iAs). Doing this we have the problem that JDeveloper do not support the java.naming package. We have added the package to JDeveloper but we do not know ik Oracle 9iAs will work with this package added.
Can someone give me some information about the use of JNDI within JDeveloper and Oracle 9iAs

One solution to this problem is to make sure that the complex type you are using in yous service interface do implement the JAVA Bean as per the spec (at least Oracle's interpretation of it).
You need to have getter/setter for all members and you need to have an empty ctor() to create new instances of your objects. In some cases, the design time let you get by, but the runtime fails in the code generation.
In your case, the 'Task' class may have some issue.
Hope it helps,

J2EE Web services and JAX-RPC

Hello..
While working with J2EE web services using JDeveloper and OC4J, I noticed that it really doesn't confirm to Sun's JAX-RPC standard. The Web Service interface class does not extend the "Remote" and all methods don't throw "RemoteException" as mandated by JAX-RPC standard.
I have few questions:
(1) Are the OC4J J2EE web services completey different from JAX-RPC based web services.??
(2) Does Oracle have any implementation of JAX-RPC??
(3) Is Sun the only one promoting and implementing the JAX-RPC standard? Or are there other players?
thanks...

(1) Are the OC4J J2EE web services completey different from JAX-RPC based web services.??
OC4J J2EE Web Services originate from Oracle/Apache SOAP with several differences:
a. A model where each type of implementation gets a specific servlet (e.g. one for EJB's, one for PL/SQL, one for stateless and stateful Java classes. Architecturally, you can see the picture here:
http://otn.oracle.com/docs/products/ias/doc_library/903doc_otn/generic.903/b10004/orawebservices.htm#1024808
(scroll down a half page for the picture)
b. The packaging of the Web services rather than using the Apache SOAP registration mechanism uses something closer to JSR 109 (also known as Web Services for J2EE, part of J2EE 1.4 with JAX-RPC, SAAJ [SOAP API forAttachments in Java] and JAXP [Java API for XML Parsing]), where the Web service is packaged as an ordinary ear file for deployment.
Oracle built this implementation by extrapolating from the JAX-RPC documentation that was available last year before it was a final specification in an effort to release a production quality Web services implementation that was aligned with JAX-RPC. It has been through two releases - Oracle9iAS 9.02 and Oracle9iAS 9.0.3 and is now being evolved to JAX-RPC as we move to J2EE 1.4.
(2) Does Oracle have any implementation of JAX-RPC??
We are planning to release a JAX-RPC implementation in the new year (I don't have specific dates yet) on OC4J. The production implementation of this will be as seamless a migration as possible from the existing implementation. Oracle9i JDeveloper will also add support for JAX-RPC as a 3rd option in its list of choices available. You can get a sense of how such a migration would work by running the Web services wizard in JDev for Apache SOAP and then, in a separate project, running it for Oracle9iAS J2EE Web Services - imagine there being another option for JAX-RPC. The work to migrate should be as simple as running a wizard or command line utility (known as the Web Services Assembler tool in Oracle9iAS).
(3) Is Sun the only one promoting and implementing the JAX-RPC standard? Or are there other players?
Pretty much every one in the Java side of industry will be implementing JAX-RPC. The important time to note is when J2EE 1.4 is released ... sometime in the new year ... I believe around March but may be mistaken. Part of J2EE 1.4 is required support for JAX-RPC, SAAJ, Web Services for J2EE etc etc. This will standardize the implementation of Web services. Oracle, like others in the industry, supports the standard protocols, (SOAP), interfaces (WSDL) and registries (UDDI) - what J2EE 1.4 does is standardize the packaging, deployment and implementation (the wrappers generated by the tooling).
My guess is that around JavaOne (June 2003) there will be a rash of announcements from J2EE vendors announcing support of JAX-RPC and J2EE 1.4 (or early implementations) as we will be in the same race that happened in 2001/2002 when J2EE 1.3 was the spec to announce implementations around.
Mike.

OC4J And Oracle 9iAS 1.0.2.0.0 And RMI Application Deployment

We have Oracle 9iAS 1.0.2.0.0 on Tru64Unix, two simple questions
1) Can we install OC4J on Oracle 9iAS 1.0.2.0.0
2) How can RMI applilcations be deployed on Oracle 9iAS 1.0.2.0.0 with or without OC4J. I mean is RMI naming service
is available on 9iAS that we can avoid running rmiregistry manually.
Thanks in advance

Oracle IAS 9i is Glibc 2.1 based, as opposed to Oracle9i EE, which is Glibc 2.2 based. You need to install glibc 2.1 stubs which can be downloaded from their patch site.

JNDI params for (default) J2EE naming service.

Dear All,
I am trying to get a client program to access a session bean using JNDI. Could anyone tell me how the naming context should be set up (i.e. what -D command line params to use).
Assuming the server Sun's J2EE and beans are deployed using deploy tool;
What parameters would be required to do a lookup on the naming service?
i.e.
java.naming.factory.initial=???
java.naming.provider=???
any others?
The reason for this is so that EJB clients can be installed WITHOUT having to also install J2SDKEE too.
In principle it should be possible to do the lookup using only only javax.naming and javax.rmi. (Which are in the standard SDK).
Can anyone help???
JNDI Code...
/* What naming params will make this lookup */
/* on an EJB running within J2EE */
/* work?? */
Context context = new InitialContext();
Object obj = context.lookup ("crs472/SimpleConverter");
// get a reference to the home interface
CurrencyConverterHome converterHome =
(CurrencyConverterHome)PortableRemoteObject.narrow(obj,
CurrencyConverterHome.class);
// create an instance of the currency converter EJB
converter = converterHome.create();
System.out.println("Got the home interface OK.");
// Start calling methods...
Regards,
Jeremy Townson

hi
u have to pass a properties object or a hashtable while creating a IntialContext object
this properties obj or hashtable should be having values for these keys
javax.naming.Context.INITIAL_CONTEXT_FACTORY -class name provided by the naming service")
for websphere its - com.ibm.ejs.ns.jndi.CNInitialContextFactory
Similarly for weblogic , Sun J2EE
the other key will u have to provide is the
javax.naming.Context.PROVIDER_URL - ip address along with the port on whcih the naming service is listening for the request
then u passs this properties obj or the hashtable to the
Context context = new InitialContext(props/hash);

URGENT - Oracle 9i, Oracle 9iAS, and Oracle 9iAS Portal Installation Problem

ERROR :
1. Objects with type JAVA CLASS with more than 30 characters are truncated to 30 characters
2. There are only 30 objects with type JAVA CLASS are installed (instead of 334) mentioned on the troubleshooting guide
3. Oracle9iASHttpService automatically stops after starting the service
Environment :
Windows 2000 Server
Oracle 9i 9.0.1.1.1
Oracle 9iAS 3.0.9.8.2 (Oracle 9iAS 1.0.2.2.2a)
PDK Services for Java version 3.0.9.0.4 (from Patch used to install 3.0.9.8.2)
Patches 8.1.7.1.1, 8.1.7.1.5, 3.0.9.8.2
I installed the Oracle 9i, 9iAS, Portal and the patches based on the installation instructions (http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/OTN_CONTENT/DOCUMENTATION/INSTALL_GUIDE_9I.PDF)
I tried adding the Sample Web Provider I got ORA-29531 error on HttpProviderDispatcher. Then I checked the Patch 8.1.7.1.1 installation, they are some scripts that need to be run that was not part of the 9i/9iAS installation instruction. I run the suggested scripts(catalog.sql, catproc.sql and utlrp.sql) and modified the jserv.properties to point the xsqlconfig.xml to ORACLE_HOME\oracore\admin.
The error still persisted. From the Troubleshooting PDK Services for Java, one of the suggestion is to run the sql command :
Select object_name, object_type, status from user_objects where object_name like '%HttpProvider%';
which resulted to an object with name '/3334f18_HttpProviderDispatche' without the 'r' at the end
and
Select count(object_name) from user_objects where object_type='JAVA CLASS';
which resulted to only 30 VALID object. According to the installation instruction, there are supposedly 334 objects.
I checked the object_name of the other JAVA CLASS objects, all the names of the objects are all less than 30 characters. It looks like that the objects with the object_name > 30 are truncated to 30 characters.
Then I rebooted the machine, when the machine went back on Oracle9iASHttpService stops automatically after it has been started.

I have posted question on that thread and there is no specific solution from our problem. From the Oracle PDK Troubleshooting PDK Services for Java, it looks like there is a problem on the Oracle Portal installation. I tried recompiling the packages and my problem worsened. Now I cannot start the Oracle9iAS HTTP Service.

Enterprise Business Services and Oracle Service Bus

Hi,
We are using AIA and we have developed a number of EBS’. These are composite applications containing a mediator and are deployed to the SOA Server.
Am I right in saying that another option is to use the Oracle Service Bus and replace the composite application ESB’s with ESB’s in the Oracle Service Bus?
Robert

Gerhard,
I was thinking the benefits would be:
-     End point Virtualisation – Single end point for services we can configure.
-     Move the job of wiring the integrations from Development to Admin
-     Single point of monitoring for SLA’s and QOS
-     Improve visibility of ESB’s by providing a single list. (At the moment they are amongst many services in enterprise manager.)
At the moment we have 3 SOA servers connected to 6 systems. (Dev, Test and Prod) I was imagining it might be possible to have a single OSB with Service routing controlled by policies. This way we would not need three OSB setup’s.
I am also charged with planning for the development of further services and we already have a long list of composites in enterprise manager. I am imagining that this will quickly become unmanageable. With OSB we could hide the downstream services and only show the EBS’.
I also imagined that when we introduced a 11.1.1.6 SOA server we could simply adjust the routing rules at the OSB to set up a dev environment. Test out the new services work, then make similar adjustments on a per EBS basis until we have migrated completely to 11.1.1.6.
I agree that there are a lot of trade off’s and I do not really have the experience to weigh up the balance between the two. Yesterday I was asked to come up with methods of monitoring performance of the current integration as well as future integrations and the OSB data sheet talks a little bit about this which is why I am thinking more about it; Although have only got as far as looking at the OSB data sheet and some manuals.
I guess another option would be to go with some EBS’s as mediators and others on OSB but I think using a consistent method for EBS’s would be preferable.
Also there is the question do we have one OSB for all systems or separate OSB’s for Dev, Test and Prod.

Using J2EE EJB Container and Oracle 8.1.7

I am trying to setup the J2EE EJB container to use and Oracle 8.1.7 database instead of Cloudscape. So far I have done the following
0. Created the table for the Savings Account tutorial in the Oracle Database.
1. Added the Classes12.jar (Oracle's latest JDBC thin drivers) to my CLASSPATH
2. Under "Server Configuration" I added the standard/jdbc drivers value: "oracle.jdbc.driver.OracleDriver".
3. Under "Server Configuration" I added the standard/datasource value: JNDI name "jdbc/Oracle" and JDBC URL "jdbc:oracle:thin:@10.1.1.254:1521:DEV".
4. For the savings account tutorial, when deploying I specified "jdbc/Oracle" for the reference "jdbc/SavingsAccountDB".
I have gotten this tutorial to work using the Cloudscape database. After I did the previous steps and tried to run the client, I get no valid driver available, unable to connect to Oracle.
What else to I need to do?
My setup is:
Windows 2000 Professional
J2EE (JDK 1.3.1)
Oracle 8.1.7
Thank you in advance.

Exactly which classpath did you add the Oracle JDBC library jar to ?
The thing that works for me is to have the following line in the file %J2EE_HOME%\bin\userconfig.bat
set J2EE_CLASSPATH=D:\DownLoad\Oracle\classes12_01.zip;

Naming Service in Oracle Net Manager

Hello,
I've downloaded ODTwithODAC1020221.exe and did the install ODP.NET sucessfully and when I try to create a Naming Service by Clicking on the + icon nothing happens.
I have a working TNSNAMES.ORA in the ADMIN/NETWORK folder where I installed the ODP.NET. In the same folder I have SQLNET.ORA and a LISTENER.ORA files.
I am using Visual Basic 2005 for my GUI.
Thank you,
Fred

I click on the '+' sign or use the menu 'create' option but I do not get a screen to enter any information.
I hard coded my tnsnames connection in my application and it work fine.
Thanks for getting back to me with the information and link. I've tried all possible combination without successfully being able to use the 'Naming Service' function.

Generating a Web Service and Oracle DATE type

Hi,
I need to generate a Web Service from an EJB model based upon entities generated from the Oracle 11g database that contain DATE types.

Web Service and Oracle HTTP Server

I have a web environment with Oracle Database 10.2.0.3 , oracle http server (using mod_plsql), Oracle pl/sql web toolkit. I need to create a web service that is accessed externally which will interact with the database (select, insert, delete). Is it possible to publish a web service to the Oracle Http Server or to implement web services with the environment above

Hello,
In RDBMS 10g you cannot directly expose WS from the DB you need to use the OracleAS Web Service Runtime to do it, following this documentation:
- Developing Web Services that Expose Database Resources
This is true if we are talking about "tooling/runtime/API" but after all Web Services are mainly XML (WSDL and SOAP) so it is still possible to create by hands (PL/SQL & static files) but it is probably a long work depending of the complexity of your services.
Also, in RDBMS 11, you can now directly expose WS from the DB using the embedded HTTP server, see this Oracle 11g New Features Document
Note that before taking one approach you must take time to write up your requirement regarding Web Services eg: do I need security, which time of encoding, interoperability, ..., ... For example WS-Security that is the standard to secure SOAP messages is not (yet) supported by the Oracle 11g RDBMS Native Web Services... where when you do use the WS-Runtime you can secure the Web Service..
