SSL certificates and Web Services Usage inside Oracle Database Questions!

We have implemented a specific business logic using PL/SQL for our client, so we open a file and process each line of this, doing something in the Database and also call a Web Services (Service1) using UTL_HTTP package. Service1 runs in a Windows 2008 Server in the DMZ as Database server.
Service1 is already working, and we can call the service from PL/SQL without troubles.
However, according with security client's policies they requires all Web services be consumed via https including Service1, so we must to follow the procedure established for Oracle in order to enable the calling of service1 via https from the Database.
Our client's DBA and IT Team are concerned about two subjects before to continue to follow the certificate installation:
     - SSL Certificates:
1- Can installed certificates in the Database put in risk the stability of the database?
          2- Can installed certificates in the Database generate performance issues?
          3- Can installed certificates reloading the Databases?
          2- Can installed certificates in the Database generate security issues?
     - Web services:
1- Can web services calling from the Database put in risk the stability of the database?
2- Can web services calling from the Database generate performance issues?
3- Can web services calling from the Database generate security issues in the DMZ?
Could you please give us any clues, about the possible negative impact related with the SSL certificates and Web Services Usage inside Oracle Database, if it’s the case this impact exists?.
Those are the links describing the procedure mentioned above.

You are correct in that there should be no problem interacting with a Web service that has an HTTPS endpoint as long as you create a wallet and specify it when you make your UTL_HTTP calls, like the PayPal example.
I am not aware of a PL/SQL utility to create a XMLDsig Standard message, but if you find some Java source out there that does it, you may be able to follow a technique I used for a similar use case:

Requirement to have email and web service.

I have Verizon wireless and they are telling me that I am required to have the email and web service on the Blackberry and I was also told that I needed for the operation of the phone to operate as a regular phone. Is this true? I wanted them to take off the email and web service until I could get another job because I can't afford the 30.00 dollars per month but sill have the phone use as a regular phone. I was wondering if it is Blackberry or Verizon that is requiring this.

It is Verizon requiring that. You are using their network, and they have a right to require what they wish while you use their network.

The Oracle Database Programming using Java and Web services book is out

This book http://www.amazon.com/gp/product/1555583296 shows how to build pragmatic applications using the combination of PL/SQL, Java in the database, JDBC, SQLJ, JPublisher, and Web services. It is intented for database developers, DBA, data architects, Java developers and Web services assemblers.
My blog http://db360.blogspot.com/ and the free/sample chapter http://www.oracle.com/technology/books/pdfs/mensah_ch1.pdf will give you a feel of the content.
Enjoy, Kuassi

Hi Kuassi,
Thanks for letting us know that your book is available. I have been following one of your articles about "Virtualize Your Oracle Database with Web Services". More specifically "The Database as Web Services Consumer". I think that this is an area that has in the past been under estimated as to the potential benefits.
I am currently trying to develop a solution that consumes several interfaces with a couple of them being published web services, so an ideal solution. I have then spent the last three weeks having to read up about the architecture of Java in the database, Jpublisher and make sense of how it all works together.
I have got very close to getting one of the web services to work but failed due to using 10gR2 where all the java & libraries has moved to version 1.5. The solution is to load the jdk1.4.2 and configure jpublisher to use this. So far so good except this is not available on some platforms, Windows - 64 bit (not itanium).
The configuration is proving very challenging but will hopefully reap rewards.
(Thought I would give you some background to my experience).
Anyway my question to you is having looked at Jdeveloper it appears to do almost anything except consume services into the database, also with Java now being at version 1.5 outside the database for 10gR2 and supporting 1.4 inside, do you see some alignment of these in future database releases?
Finally off to buy your book now as no doubt there is a huge amount more to learn.
Kind Regards

Digital Certificates and Web Services with Oracle APEX

Hi people,
I am working to implement Web Service communication using Oracle Apex. I need to create an application that calls an external public Web Service in Apex. So far, so good, and i am able to work with a public WS without any problems.
However, this particular WS I'm calling has two peculiarities:
1) It is SSL-Secured (HTTPS). This means i have to communicate using SSL and Public/Private Certificates.
2) The message i pass (payload) must be digitally signed using XMLDsig Standard (www.w3.org/TR/xmldsig-core/)
The first requirement i am still testing, but it will probably work if i import the public and private keys using Oracle Wallet and point to this Wallet, just as PayPal sample in OTN samples does, don't you think? Should i have any problems with this?
The second one is more complicated, all APIs i have seen for XML Digital Signing are Java-based or .NET-based, i have found nothing based in PL/SQL packages or such. Can you point me some other options to sign this XML?
Please bear in mind that, since the WS has more than one method, i am using plain old UTL_HTTP to call it (just like the PayPal sample in OTN). PayPal requests that all communication be SSL-enabled, but has no mention whatsoever for Digital Signatures.
Can anybody help me out with this? any help is highly appreciated.
Regards
Thiago

Problem with Oracle Web Service Proxies reusing classes and exceptions

We have an application that have many web services and we're having a really hard time working with Oracle Web Service Proxy. We have many web services that share the same classes for parameters and exceptions. When we generate de proxy classes, it generates a lot of _LiteralSerializer classes. Because I'm reusing the same classes and exceptions it generates the same _LiteralSerializer classes for this classes and they get replaced. For Example
I have classes A and B and Web Services X and Y that use this classes. When I generate the 2 proxies it generates A_LiteralSerializer and B_LiteralSerializer on the 2 proxies and they get replaced and I get "No serlalizers for A class or B class". This problems repeats a lot of times and this problem is a huge risk for our project. We're using JDeveloper 10.1.3.4.
Is there a way to avoid this with Oracle Web Service Proxies?
Regards,
Néstor

Resolved when I create a deployement profile explicitly.
The Webservice.deploy that gets created automatically when I create a web service was giving this issue.
Thanks

J2EE and Web Services

Hi forummates,
In the traditional architecture, the communication between EJB is RMI/IIOP. Web Services can be looked as a communication between classes on SOAP/HTTP.
How should we use Web Services in J2EE in the maximum effeciency? Is there any good example of using Web Services in J2EE (1.4 is a must?) ? Please advise.
Lawrence.

Hi Lawrence,
I would look at the J2EE blueprints on web services to get started. You may also want to take a look at the J2EE tutorial and web services tutorial. Links below:

Oracle Workflow and Web Services

Hi
does anyone know whether we could handle Web Services from within Oracle Workflow?

There is a white paper on OTN about communicating between BPEL and Workflow using java event subscriptions - all you need is to have BPEL installed as well. If you can do that, you should be able to communicate with web services.

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
Krishan

Did you got the solution for the issue you had?

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.

(261680070) Q SYNCH-11 How do my web service methods accees EJBs and java classes?

A<SYNCH-11> How do my web service methods accees EJBs and java classes?
A<SYNCH-11> It is simple to use java classes, just do it as you would ordinarily.
The .jws file really contains a simple class so you can program with it in the same
way that you would use a regular Java class.
To use an EJB you can go and access it directly as you would with any EJB remote
client (lookup home stub, create, etc) or if the EJB is deployed to WLS you can use
a control to provide a very simple wrapper to the EJB. We will see this in detail
on Thursday in the ADVC module.

Futher information about the possibility of callback:
It may be possible for a synchronous only web service (i.e. MS .net) to even paticipant
in the callback functionality of asynchronous web services. If the client implements
the appropriate methods for the callback but listens for them on a different port
or binding than the SOAP request, then web service may be able to build a response
if the client's "callback URL" is submitted as the beginning part of a conversation.
Watch the BEA developer forum (http://dev2dev.bea.com) for more information about
this approach and other tips and techniques for building web services.

Q<SYNCH-03> I heard that MS .net only implements synchrnonus method? If
this is true.
Does it means my async methods will only work with J2EE clients?
A<SYNCH-03> I do not know the limitations of .net but let me point out that
is very
difficult to provide asynchronous web service method invocation (this is
different
from an asynchronous web service). HTTP as a general communication protocol
is based
on a request and response paradigm so your client libraries will mostly
likely be
expecting a response even if it is empty (check the asynchronous example
from today
to see that the start method still returns an empty response). You must
distinguish
this from the notion of an asynchronous web service which is a business
operation
that occurs on the server whose return value/result is not directly associated
with
building response to the client. An asynchronous web service can (and generally
will)
be started and stopped with web service operations that are invoked synchronously.
Thus MS .net clients can still be client to WLS hosted web services.

GTC Connector using SPML Format Provider and Web Services Transport Provide

Hello All,
Did any body create a GTC connector which uses SPML Format for Format Provider and Web Services format for Transport Provider?
Is there any doc which talks about the same?
I need to provision to a system over web services and I thought GTC using the above formats should be an easy approach. Am I right?
I was trying to follow:
http://download.oracle.com/docs/cd/E14571_01/doc.1111/e14309/devgtc.htm#BABDFDFE
But Iam getting lost in the immerse details.
Thanks in advance.

Hi ,
I tried creating one and am getting the following error while provisioning:
SPML Response failed V2 schema validation
Th eoracle document says :Ensure that the SPML response returned by the target system conforms to the SPML V2 standard specification
Please help me with the same. What is it that needs to be done here.
Thanks
