Database Web Service Installation

Hi All,
Using Oracle 10g. Trying for Oracle Web Service Installation(Database Web Service).
Looking to implement 'Database Call-In' approach with 'Exposing a SQL Query or DML Statement as a Web Service' option.
Gone through the Web Services Developer's Guide, but unable to grasp complete process from it.
Can anyone help me in sharing, the complete requirements/Prerequisites that i should have for implementing this web service??
Also how can i confirm whether my app server has OC4J JAX-RPC processing servlet, WebServicesAssembler in it??
Dont have much clue regd this implementation. Want to know,learn more for doing this. Please let me know if any other info req for
answering my questions.
Thanks,
Sandeep

very helpful Rene..
Sharing one which was found from Web Services Developer's Guide..
http://download.oracle.com/docs/cd/B31017_01/web.1013/b28974/gettingstart.htm#BABHFFEG
any other method available to develop Web service from SQL Query rather than using PL/SQL package??

Database Web Services and OC4J in Oracle Database Standard Edition

Hi all,
Oracle Database Standard Edition has database web services, which require OC4J if the database is to be used as web service provider. So, can OC4J be used in production with Oracle Database Standard Edition?
Thank you for this clarification :)

Yes. :)

Database Web Services with Oracle 10g

Forgive my lack of knowledge on this issue, but we are still researching our options and we have very little experience with these new technologies.
We have been using Oracle Database server for years and we are looking now into integrating or applications to offer farther solutions to our customer as well as to implement a b2b solution.
Our b2b solution consist of a relationship between Partners of our customer via a hub server that would reside on our quarters. In other words our customers servers would communicate with their partners via our server and vice versa.
We are planning to use Fusion to implement our Hub server and my question is:
"Should we deploy A J2EE container to our customer where 'client services' would run to maintain a runtime communication with our hub or can we skip the J2EE container by using Database Web Services?"
And a related question:
"What Oracle components are required for Database Web Services to work? How are they implemented?"
Thank you!

After farther reading about Database Web Services, it seems that you still need at least OC4J on the customer side to run Database Web Services. Is that correct?
So if the best approach is to deploy OC4J to our customers, how difficult is to do so and how can I configure each one of my customers so my hub server can uniquely identify each one of them?

P6 R8.1 Web Service installation issue on Linux

We are trying to install P6R8.1 web services on weblogic in linux. We have the following setup:
1. Oracle 11g standard database in CentOS-5.4 64-bit
2. P6R8.1/ Weblogic 10.3.3.4 installed on CentOS 5.4 64-bit (separate server).
We have installed as per the oracle installation guide without any warning/ failure. After deploying the .war file (p6ws.war), it also showing Active in Weblogic admin console. But while trying to access the application (http://localhost:7001/p6ws) we are getting error: 403 Forbidden.
We have tested the weblogic by deplyoing some sample .war file and it works fine
After examining, we have found that there is no index.jsp file in the root of the p6ws.war file and it is only 29 mb compare to primaveraweb.ear file which is 194 mb of our existing installation (P6V7 with similar environment).
Is our .war file is not properly generated or we are missing some steps? Or there is any other issue?
Any help will be highly appreciated.
Best Regards,
Sandip

In previous versions the following was sufficient:
http://HOST:PORT/p6ws/
The correct URL as of version 8.0 of P6 Web Services is the following:
http://HOST:PORT/p6ws/services
See the following: "Error 403--Forbidden" When Attempting To View Available Services For P6 Web Services (Doc ID 1293112.1)

Hi,
The error message said
the Permission(java.lang.RuntimePermission getClassLoader) has not been granted to USF.
I'd follow the suggestion
The PL/SQL to grant this is dbms_java.grant_permission( 'USF','SYS:java.lang.RuntimePermission', 'getClassLoader', '' )
In case you have not done so, consult the Callout Users Guide @

How to include the NIWebAppServer.conf when building a web service installer in LV2010

Hi all,
I'm build a LabVIEW 2010 web service and creates a deployable setup installation as described in Web Services FAQ:
http://zone.ni.com/devzone/cda/tut/p/id/7747#toc12
but also would like to include my .conf file for the NI Application Web Server. The file is located in:
C:\Program Files\National Instruments\Shared\NI WebServer\NIWebAppServer.conf
This is where all settings (listening ports, SSL, users etc.) are configured.
If I look in LabVIEW 2009 build instructions for web services:
http://digital.ni.com/public.nsf/allkb/62B9C2D5C91EE8B28625778800609FF2?OpenDocument
they include this file, but it is a new procedure in LV2010 (as seen in the top link) and I can't seem to get this conf file included and installed on the deployed system automatically for LV2010. Today, I must copy it manually.
Any ideas of how to do this?
Thanks,
Mattias

Having the same problem, even if pointing the installer to install the particular file, the installer will install its own some default file. Did you find any solution?

10g : database web services

Does JDeveloper 10g support web service deployment to the database?
Thanx
Andrus

Currently you need to carry out a few steps to deploy web services to the database from JDeveloper
1. Load the SOAP client stack (one-off load)
see http://otn.oracle.com/sample_code/tech/java/jsp/loadjars.html
2. Use the JDeveloper wizard to generate a stub to call your web service
3. Manually create a second stub class with a static method to call the generated stub. The database requires this. For instance (where MyWSStub is the stub and MyWSStaticStub holds the static call):
package model;
public class MyWSStaticStub
public MyWSStaticStub()
public static String callMyWS(String s)
MyWSStub new MyWSStub(s);
4. Create a database deployment profile (File-> New -> Deployment Profile -> Load Java and Stored Procedures) and select your stub and static stub as the classes to be deployed
5. Right Mouse menu of the deployment profile -> Add Stored Procedure and select the static method (callMyWS)
6. Deploy the profile and use the Stored Procedure (deployed with the profile) to call the service
In the future we hope to automate these steps
Hope this helps

NEED HELP WITH DATABASE WEB SERVICE INTEGRATION

Hello everybody. I have created a web service with returns a list of records extracted from a database. It works, Apex references the web service and get the result when I test it, but I want to display results in a page type "Form and Report on Web Service" and when I associate the web service to the page and click on "Finish Button" I get this message:
"This Web service does not have a result tree in its definition that is appropriate for a report. You may wish to run the Form on Web Service wizard instead.".
It is correct, of course, but I do not have an example of how to do an appropriate definition for this kind of report.What kind of definition is it waiting for? What I do in the web service is to return a list of items (a resultset of a query such as "SELECT PRODUCTID, PRODUCTNAME, PRICE, IMAGEHREF FROM PRODUCTS") concatenated in a string (commas-separated values). What kind of output must the web service produce or how have I to structure the associated wsdl document in order to display the result with a "form and report on web service" page?
Every help or example is welcome.
Thanks a lot and have a nice day

Dear dvohra16,
Thank you for the great book you're recommended. It's really a powerful tool that makes things much better for me.
I've noticed that you're the author of this book. I'm really honered to discuss with the problems I have and
I'm so lucky to get your responses for my questions.
My current question is based on this book. How do I orchestrate a web service that inserts into an oracle database table and a web service that reads
the contents of that table?
In other words, the first web service inserts some values into a table and the second should read these values.
So, how does BPEL orchestrate these web service such that the output of the first one is the input of the second?
Your assistance is truly appreciated.
Thank you for your time.

P.S. I can see the wsdl file at the following url
"http://server-name:5432/ZeraRAWebServices/jaxrpc?WSDL", but while calling it from Perl routine it does noting, just log an error in catalina.out log file.

Have you figured out a solution for this problem? I recently encountered the same error message, when I attempted to take a working web service I have built and move it from Tomcat 4.0.5 to Tomcat 4.1.12. I have not changed anything at all, and now I am getting this "failed to instantiate service implementor for port ..." error very similar to what you have described.

Web Services Installation

Hi...
If Im going to create an agent on ODI .. now Im encoding the password, the cmd provides the password but is a warning about the web services... its necesary insttall them???

Hi ,
It is not essential to install web services for ODI to work .
And I believe the warning is about not using a JDK which is required for ODI web services .
"A JDK is required to execute Web Services with OracleDI. You are currently using a JRE."
Thanks,
Sutirtha

Database Web Services call-out with 9i

I am trying to test the callout utillty with DB 9.2.0.5.
I have downloaded the sample for 9i but having problems loading the java classes.
I am not interested in using jPublisher, I just want to be able to call webservices from within the database.
The instructions say that utl_dbws.jar is only used for jPublisher and just needs setting in the classpath. I have down this.
When I run loadjava I get hundreds of classes unresolved, and when I look in the database lots of classes are uncompiled. I try and compile some of them and they often refere to classes that have not been installed.
How can I resolve this?
I have seen NOTE 338092.1 which refers to using an option -genmissing, does this work with the earlier releases of the DB?
Has anyone ever got this sample code to load and work on a 9.2.0.5 database?
Any help appreciated.
Stuart

I think at first you have to load some jars in the database. i.e the Oracle SOAP implementation for JDK 1.3.
I tried this. I used the jars from an older OC4J. It was not easy. Oracle compiled 2 classes with the wrong target. I recompiled it in the database.
I generated the Stub with Jdeveloper. (I don´t want to install JPublisher) and load in the database.
All classes was compiled and valid.
The stub still does not work in the database. I got an ClassNotFound Exception in the Aurora VM.
I gues Oracle WS Client implementation for DB 9.2 is not perfect.

Error received when calling web service from database.

Hi folks,
I am trying to call a web service from the database (using the Oracle database web services call-out utility) and I am getting the following error:
ERROR at line 1:

This web service is deployed on Oracle app server 10.1.3.4. It calls a BPEL process which in turn calls Oracle Business Rules.
I used JPublisher to create the stubs for the web service and load them into the database.
Any ideas on what might be causing this error?
Thanks.
Kashif

Well, I think so... I've followed all the steps, and my merged WSDL file seems like the one in page 12...
Any suggestion, please?
Thank you,
