Transaction inside web services, what does Oracle AS provides?

Hi
Thank you for reading my post.
we have tens of web services that we want to deploy them inside one instance of Oracle AS, now we need to have some transaction support in several levels :
- When we insert data into database in a single web services.
- When we have JMS interaction in a single web service.
- When we have JMS + Database interaction in a single web service.
- When a taransaction start from one web service and it must propagate inside second web service and second web service will decide whether it should be commited or not.
What does Oracle AS provides in this area?
If there is no support for this kind of scenario in Oracle AS, then what we should do?
Thanks

Hi,
1) if you are using Oracle Database 10g JDBC, it can pool connections for you, transparently -- if you are using Oracle AS or Oracle9iAS, you can just use JPublisher to generate the wrapper and deploy it.
2) SSB is too heavy for just placing a JDBC call.
3) a Servlet is lighter-weight that a SSB however, the Web services framework itself uses a Servlet to marchall / unmarshall SOAP messages -- unless your middle-tier requires a J2EE programming model (such as Servle or EJB) to pool JDBC connections
4)For calling-in database operations as web services, our implementation requires the Oracle AS (or Oracle9iAS) OC4J middle-tier (see #1) however, you can invoke external Web services from within the database.
See our Database Web services page for more details and code samples

Web service deployment on oracle app server, need help

Hi All..,
When I deploy a web service on the Oracle Application Server (10.1.3.3) the WSDL that is generated from JDeveloper and package with the EAR file is overwritten at deployment time. The parameter names for the method calls for the web service are change from actually parameter names to generic ones. For example, “amount” is changed to “param0” or “vendorId” is changed to “param1”. Is there a way to not let this happen ??
TIA

Issue with creating Web Service Client using Oracle JDeveloper

Hi All,
I am trying to create a Web Service Client using Oracle JDeveloper. I set the Project compiler property to JRE 1.4
When I run the web service client, it throws me bunch of errors saying:
'Error(32,2): annotations are not supported in -source 1.4'
I am wondering why JDeveloper is using annotations even after I set the compiler property to 1.4
I am following this link to create the webservice client:
http://www.oracle.com/technetwork/developer-tools/forms/webservices-forms-11g-094111.html
Any help in this regard would be greatly appreciated.
Thanks,
Scott.

Dear Shay,
Thanks for your prompt response.
You are right. JDeveloper 11g uses JDK 6 style annotations for the clients it creates. But you can change the JRE Version used at compile time by following these steps:
1. In the Applications Navigator, right-click the Project Nanem node and select Project Properties... from the context menu.
2. Select the Compiler node and check the Source Files and Generated Class Files dropdown lists. You may change these versions depending on the version of the JRE you are using with Forms to ensure that the compiled
classes from JDeveloper can be read by the JRE used by Form.
So I selected JDK version 1.4 there.
Sorry that I did not mention that we are using Oracle Forms 10g. That is the reason I selected JDK 1.4
Thank you.
Scott.

Calling Oracle Report InSide Web Service Method

Is there way to call oracle reports inside one of my web service method.
If yes kindly let me know how we can do this and some documents related to this.
Thanks
Robert

Oracle reports does have a Web API when reports are run from the application server. As a result one way to do what you are asking is to write a Web service that use java.net.URL to invoke the Reports Service Web interface:
http://otn.oracle.com/products/reports/htdocs/getstart/docs/A92102_01/pbr_run.htm#1005598
As I understand it, this interface itself is actually being exposed as a Web service in a future release of Oracle9iAS Reports ... I don't know if this is a Oracle9iAS Reports 9.0.4 feature or beyond that. You might try asking on the Reports forum:

What Web service client does Omniportlet use?

Does the omniportlet uses direct SOAP calls for Web service or use AXIS calls??
Thanks
JO

Hello,
As you may know OracleAS / JDeveloper has its own Web Service runtime and set of Tools. Omniportlet uses the Oracle AS Web Service Client API and WSDL tools to invoke dynamically SOAP based Web Services.
I am curious to know why are you asking this question? Do you have specific requirements?

Security issues with calling web services from within Oracle?

I'd like to use a trigger to initiate pushing data to a web service, so I thought we should call the web service from PL/SQL in a DBMS job, or perhaps create a .NET stored proc to call the service. Our DB Lead is concerned about security, since the standard model is for clients to call the database, and not for the database to function as a client.
Does this pose any security risk? Can you refer me to any best practices or articles on this?
Thanks in advance.
Edited by: Kit.net on Nov 9, 2010 11:28 AM

First, a trigger is there to for a single sole purpose - guaranteeing the integrity of the data and the transaction. It is not there to interact with external services and processes (like mail, web and other services). Doing that exposes the transaction to those other processes/services. The transaction can now fail. not because of a business rule validation, but because of a network error when the trigger accesses an external service. How on earth can a business transaction fail when the transaction is valid, but a the transaction's trigger hit an external access error!?
And what happens do that event you have fired off in the trigger, when the transaction is rolled back? How do you undo that event you have created in the trigger that was based on uncommitted data?
So using a trigger like this is simply stupid (and yes, I have seen it too often in practice with horrible results to sugarcoat such an idiotic approach).
As for calling a web service from the database, using the database as the client in such a case. This is not a security risk. This is not unusual. In fact, it is very common in my experience. We have a lot of databases, ranging from SE to EE and several RAC clusters. All of them function as a client at some stage during processing. Some use a db link - and as a client fire off a SQL via that db link to a database server to obtain data. Some use ftp and act as a ftp clients, transferring processed data (XML format) to a server. Some call web services to extract data from 3rd party systems to reconcile the differences between local data sets and 3rd party data sets..
This is common between server and server. I do not see anything unusual in the database server using another server (and acting as a client when it does). Security between servers should not be a major problem (in fact, it can easily be done in a very robust way using trusted and encrypted communication).
The problem occurs when a client connects to the server and client and server roles are swapped at some stage (like the server "writing" a file directly to the client's filesystem). This very seldom makes any sense. And this is where authentication and security become an issue.

Web Services - What is the right strategy to follow?

Hi,
I want to consume web services directly into the database, the application is all to be within the database no website or clients. Based on the calls to the external provider I then want to be able to send request back. I want to use pl/sql inside the database as opposed to java.
I have the wsdl file and jdeveloper has generated quite a lot of java objects based ont this. This is about as far as I have got. I read somewhere about loading java web services client directly into the database.
Any guidance would be appreciated.
Thanks David

Hi Sunil,
Thanks for the link, I also found what I think is a pretty up to date solution at:
http://www.oracle.com/technology/pub/articles/mensah_dws.html
I am sure this is possible all in jdeveloper but to many wizards, frameworks and options that you could want!

How can we call a WEB SERVICE from an Oracle DB?

<h2>
What the methods available to call a WEB SERVICE from the DB. I.e. through a DB Stored Procedure?
I was given this article by a colleague, but since it’s a 2005 one, I feel it could be outdated?
http://www.oracle.com/technology/pub/articles/mensah_dws.html
Also, is it possible to write ONE “Common” DB stored procedure to call ANY WEB SERVICE?
</h2>

<h2> No Girish, what I meant is, since it is 2005 article, the method it describes to call a WS is out of date.
Because I am quite sure in 2009, 4 years later Oracle must have added built-in packages and other methods to simplify it???
Also, I would be very grateful if you advice on the other issue: Is there a way to create a single DB stored procedure to call ANY WS?? i.e. a common routine to call any web service?

Now, when I am using http://<<server>>:50000/XMII/SOAPRunner/TAG_TRX to create a Enterprise Service in SAP (i.e. SE80 transaction-> Create Enterprise Service-> Service Consumer-> URL/HTTP Destination-> URL ... I am getting following error.
Incorrect value: Entity "<<document>>"(5 /93 ). unexpected symbol: '<'
But, whenever I am using the same URL in MII BLS, it does not give any error. It correctly shows all input and output parameters.
Please help me to resolve this issue.
Regards
Neeta.

Now, I am able to create the Web Service in SAP and it is now showing the respective class, attribute and methods to execute this web service (web service to call MII transaction).
But when I am calling it from ABAP (a simple Web Dynpro for ABAP method), it is showing me the following error:
Error (id=GET_BUSINESS_SYSTEM_ERROR): An error occurred when determining the business system (LD_ERROR)
Thought this error is coming from ABAP program, but I am sure that this is related to some configuration at SAP level. (Let me inform you that there are two different servers for SAP Web Dynpro ABAP and SAP MII.
Please help.
Thanks in advance.

Error calling BLS Transaction as Web service

Hi,
I am trying to call BLS tranx as Webservice from another BLS Tranx.
I craeted the simple BLS with no input parameter and set only one output parameter.
Then i created the WSDL as
http://<server:port>/XMII/WSDLGen/<Transaction path>.
In new BLS tranx, i created the Web Service action block and gave this WSDL URL (http://<server:port>/XMII/WSDLGen/<Transaction path>).
I gave username and password and selected the port(XacuteWSSoap) and then operation( xacute).
In Links, I gave the Loginname and Password.
But while executing, it showed the error as
Error Invoking Web Service Action: Status (401): Unauthorized
My username and Loginname and passwords are correct only.
What is the problem and how to solve it.
Regards,
Senthil

Hi,
Which SAP MII version you are using?
I have tested one piece in MII 12.0.9 it works for me following are steps which i followed.
After WSDL generation
1. in Web service action block --> cofigure i am passing following parameters
WSDL base URL: http://<server:port>/XMII/WSDLGen/<transaction Path>
User Name: XXX
Password: XXX
2. in Web service action block --> Links I am passing following parameters
WSDLUrl : http://<server:port>/XMII/WSDLGen/<transaction Path>
Web_Service_0.XacuteRequest{/ns1:XacuteRequest/ns1:LoginName} : XXX
Web_Service_0.XacuteRequest{/ns1:XacuteRequest/ns1:LoginPassword} : XXX
Refer below SDN thread may be helpfull:
[Web Service Action Block;
Hope it helps!!

Integrating Web Services Manager with Oracle Portal and SSO

Hi,
I wanted to throw this out there and make sure I was on the right track and also if somebody can point me to some resources online that might help. Basically, we have OWSM acting as a Gateway securing some web services. Oracle Portal is integrated w/ Oracle SSO (as well as using OID). What is the best way to pass the credentials to the OWSM from the Portal for authentication purposes? I believe using SAML voucher token is the way to go, but I'm not positive. Has anybody done this before and if so, what methodology did you use? I'm assuming since using SSO, we don't necessary want to also pass in the password.
Thanks,
Nathan

I have noticed that nobody has same kind of situation and this is not intresting question. Still we have same problem and I have heard many oracle employee saing that this behaviour is wanted situation. In our kind of virtual host enviroment it would be nice to choose behaviour of Single-sign-on server and I request oracle support to find out ways to enable this option... I would be pleased if some oracle development would say opinion about this mater. Waiting for ideas.
