Web Service Best and Worst Practices within Oracle SOA Suite

Hi All,
Has anybody got a single document that concisely details the best and worst practices around the design of web services for oracle SOA and BPEL.
I'm interested the following aspects
1. Level of Granularity
2. Level of Reuse
3. BPEL orchestration. numbers of BPEL process vs services
4. Transport choices...SOAP vs REST vs Big Services etc
5. Activity Monitoring with BAM
6. Future proofing of signatures and ongoing maintenance and process change
I'm constructing a document myself to share on this forum, but i'd be very interested to use the wisdom of others if somebody has done this before...
Thanks in advance :)

This is a question best answered by your Oracle reseller or Oracle account manager to give you all the details but I hope this brief answer helps:
- The Unified Business Process Management Suite (BPM Suite 11g) includes: BPM Studio, BPM Composer, BPMN Service Engine and Workflow Extensions, BPM Process Spaces, and BPM Process Analytics.
- BPM Suite 11g requires the licensing of SOA Suite 11g for Oracle Middleware which requires a license for WebLogic Suite.
- You can license SOA Suite 11g now and license BPM Suite 11g later.
Since the products are layered, I don't see this cutting into SOA sales at all. My personal view is that BPM on top of SOA is brilliant since it provides easy integration between human and automated tasks, builds on many of the SOA concepts that are key for a successful BPM implementation (functional, not the Oracle product), and uses the same IDE. The synergies extend past easy use of services; the same business rules and human workflow components are used between both products.

I have JDeveloper installed on my system. Let me know if you need the log file.
Any help is greatly appreciated.

Andre,
I am a newbee in this field and I could not understand your question. Can you please explain? I downloded Oracle JDeveloper to design BPEL processes and trying to install Oracle SOA suite for BPEL process manager, that is where I hit this road block.
Thanks

Web Service best practice question

Hi ! I'm designing a web service solution and I'm trying to figure out the best way to solve a simple situation. I haver some products at my company which need query by consumers, I need some way to let them provide some sort of unique identifier for the product in order for me to return the product complete description. Unfortunately the products are specific to my company and there is no industry standard to do the search (like an ISBN for books). So I'm considering make an adicional service to just return the products database ID in order to enable the consumer make the actual query using this ID. Is there a better way to handle this situation ??
Thanks everyone !

services should be idempotent and stateless.
that means that transitions and workflow should be the responsibility of the client.

What is Oracle Web Services Manager and where can i get more information ?

Hi,
Can any one point me to some useful links to know abt
Oracle Web Services Manager and some example to play with it.
Appreciate your help !!

Vijay,
You can install Oracle Web Services Manager (OWSM) as a stand alone product, but the easiest way would be to use the OracleAS SOA Suite Developer Preview, that contains all the SOA components (OWSM, J2EE, BPEL, ESB, ...)

Oracle Web Services Manager and Stateful Services

Hi,
I was wondering if anybody could help or provide guidance on stateful web services and the OWSM.
I've registered a stateful web service with the OWSM. I also selected the "Keep-Alive" option as well, but this prob. doesn't pertain to stateful web services. But it doesn't seem to register the fact that its a stateful web service. When I call it, I have a packet analyzer that looks at the TCP trace and no Session id is sent back in the headers on the client side, which is on a separate box. Obviously, running it directly with Java and Axis works fine.
We are using a gateway for the OWSM, not an agent. The web service is successful in getting called through OWSM but the problem is that no session information is sent back to client so subsequent calls fail b/c the web service requires the state and what the previous call was. This web service is a .NET service and resides on a different server/box than the Oracle SOA suite.
Are there any tutorials/information out there that would tell me how to register a stateful web service with the OWSM? Eventually we'd like to connect the OWSM to an ESB and that would require it to be stateful as well obviously.
Thanks again,
Nathan

On OTN, documentation library. Search for Oracle Web Service Manager and there you will see the Extensibility Guide.

BPM Process As a Web-Service Username and Password

Hi all,
We have exposed a Process as a Web-Service WSDL to another system . We use Username Token Profile to enter the username and password to connect to the Web-Service..
Now what we do is we have a role in our project and we create a dummy Web-Service user and add the role to that user and then use its password and username to call the Web-Service.
Can we change this?
Can we have a dummy username and password not associated with any role in BPM used in our Web-Service?

Did you use PAPI code inside your web service or did u just use PAPI Web Services ( like did u just pressed the button Launch PAPI Web Services ) and it created the WSDL for you and u used it to create the client?
I am using the latest version of OBPM..
Oracle 10.3.10
Can you let me know what do u mean by PAPI interface.. Is it the PAPI code of is the PAPI Web Service which is built by BPM automatically and could be used?

Script example trigger web service call and populate request from adobe

Hello,
I'm trying to make a adobe interactive form that needs to be populated by a web service. I have one field : In the dataconnection that is the input for the web service request and this is bound to the request. I have a button that is connected to my web service. After filling in a new value and pushing the button I want the web service request to be triggered.
Thus anyone has a coding example or more information about using web services directly from within a Adobe Interactive form ?
thnx, Jasper

Hi Jasper,
You may refer the Adobe ddevelopment center for the docs related to the execute property of the button to trigger a web service.
Alternatively, if you do not want to create a button to execute a call to a Web Service, you can do it via Script.
Assuming your Data Connection is named LeasePayment
For JavaScript:
xfa.connectionSet.LeasePayment.execute(0);
For Form Calc:
$connectionSet.LeasePayment.execute(0);
execute(0) indicates no data merging
execute(1) indicates all the data in the data DOM will be remerged. - Adobe doc.
hope this will help.
Thanks andRegards,
Anto.

Call a web service in an interactive form within SAP

hi experts
I need to call a Web service into an interactive form within SAP, but to do so fails to press on the button that calls the Web service, the strange thing is that if I keep the PDF in my PC, then open that PDF download button works correctly if I am doing something wrong?, you can do what I need?.
Greetings.

Hi asdasdasdasd1,
not sure if I fully understand your problem but it sounds like you are trying to execute your Web Service in the preview tab of LiveCycle Designer. When you do this, features of the Reader Extension Rights are not available so you will have to generate the form via the ADS and test the WS on the generated rendition as you have done.
Let me now if this helps.
Regards,
Ben.

Entering values in Web Services ID and Description, for External Catalog

Hi,
I am trying to connect to an external Vendor Catalog from ERP. Pl note that we just have ERP ECC 6.0 and no SRM. I went to SPRO and followed menu path 'Materials Management >> Purchasing >> Web Services: ID and Description'. I am not sure what to enter in 1) Seq. Number 2) Name of Parameter for Web Service and 3) Call Structure COLUMNS.
I have URL from Vendor, User Name and Password. I need to know what values are mandatory here so I can successfully connect to external Catalog. If someone can give me sample values, I can try.
Any help is appreciated,
Niranjan

Update on 08/23/2011.
We are able to connect to Vendor Catalog, select items in Cart. When I press 'Place Order' button, I see all items populated in SAP PO ME21N screen. We can then add other information and create PO. This is working great. We have another question. Heard that with ERP ECC 6.0, we can only connect 1 vendor catalog. But with SRM, we can connect more than 1 vendor catalog. Is there a BAPI or change SAP code to connect more than 1 vendor catalog from ECC 6.0 ?

External Web Service - User and password in HTTP header

Hi!
How is it possible to add user and password in the HTTP header in a external web service call?
I have created a "Portal Service from WSDL file - Client side" with the wizard in SAP Developer Studio. I following the Java Development Guide - Web Service Security, and use the secured service connection. I have also created a new System Landscape, but should the new system be based on HTTP, my own PAR or what?
How can I check that the user and password is added to the HTTP header or the SOAP envelope? Do I have to scan http traffic with a proxy as Paros or can I find the request sent from SAP EP in the logs?
Cheers
Asle

Hello All,
I have been struggling a bit while putting a reasonable security framework on a jax-rpc style web service. I'm using JWSDP1.2 to set up the webservice. I've tried to outline my problem below. Please correct me where I'm wrong.
I've been through the Sun's WS tutorials, but they are not really clear on security. However, from them I surmised that there are two decent authentication techniques. HTTP Basic and mutual authentication (MA) . Both have their drawbacks though. HTTP Basic suffers from poor encryption while MA is a bit difficult to set up on both client and server sides. Another problem with MA is that there is no central repository for users/passwords.
OK, what I would really like to do is use my own user database to verify users/passwords i.e. use a HTTP Basic like authentication (but at application level) but run it over SSL for encryption. It seems simple, but is it possible?
Also, I have noted that when I use HTTP Basic on the service side, and use a java client, then setting username/password has no effect. In other words, I can always access the web-service, even with wrong username/password.
Sorry for the long post. Hope someone can help. Thanks.

Web Services, Schemas, and the xsi:type attribute

Hi List,
I have several questions reqarding web services, schemas, and the use of the xsi:type
attribute in messages.
Schemas:
Q1: How complex can a web service schema be?
Q2: Is it reasonable for a schema to contain derived types by extension [1]?
Q3: Could you use the International Purchase Order Schema [2] with a web service?
xsi:type
Q1: Is it reasonable for a web service to use the xsi:type attribute in the message(s)?
If I am interpreting Section 4.1.15 of the BasicProfile-1.0a [3] correctly, this
appears to be appropriate in certain circumstances.
Q2: When is it appropriate to use the xsi:type attribute? If a schema contains
derived types by extension [1]? If a schema contains xsd:anyType?
Q3: How does using the xsi:type attribute affect interoperability?
And finally,
Q4: Are there any examples available demonstrating the use of the xsi:type attribute
in messages?
Whew !!!
TIA,
Kent

Java Web Services wrapper and connection management.

We are currently evaluating the use of the SES Java web-services for a custom front end. I've downloaded the sample code and have read through the documentation but I'm confused on a few points.
We will be OSSO protecting the app, so the flow I think I need to use is (on the OracleSearchService object):
*setSoapURL
*proxyLogin
*setSearchUser
*doOracleSearch
(do whatever with results)
From what I can tell each one of these does a separate call into the actual web service. Does this keep a connection open between these calls and if so how do we need to manage our connections in this case. Is there an explicit close method we should be calling? I see that we can get an OracleSoapHTTPConnection from the undocumented getConnection method on OracleSearchService but I'm unsure if we are supposed to interact with it directly.
In a related vein how should we managing our OracleSearchService objects? Should we save an instance for each user in our httpSession, or just create a new instance on each call?
Any insights appreciated,
Jason

No Problem at all
Nomally the Web Service is big different between Web application. or you can build your Web service structure like web application structure. It depends on the web server:
If the Web Server of hosting company has WEB Service framework, you just need know how to deploy your Web service to Web Service framework and How to deploy to Web Server. In this case, you need deploy it two time, one is for Web Server framework and one is for Web Service framework
If the Web Server of hosting company doesn't has WEB Service framework, you need build your own Web Service framework into a web application, then you just need know how to deploy your web application with Web service into Web Server framework

Difference between Web Service Developer and Web Compononent Developer?

What's the difference between Web services Developer and Web Component Developer? What's their job description. I'm aiming to be a web application developer. Which track should I follow?

Here is another article on J2SE vs JEE:
http://www.velocityrevies.com/forums/t151124-what-is-j2se-vs-j2ee.html
I believe the people who said JSE is only for desktop development are not correct, as well as their saying their are 2 kinds of developer (web service and component).
As I understand it, web service developers provide a way to expose the data and functionality of a program written in a particular language (such as Java or C#) as XML documents to anyone subscribing to the service over the internet. The remote applications subscribing to the service therefore can be written in any other language. For example, imagine a Cobol program trying to get data from a program written in Java. Since both cobol and Java should have ways to parse XML documents, they don't have to know each other's syntax. There are many programs written in many many languages in the web and XML is a standard way for them to communicate. Web Services are an advanced topic and you shouldn't worry about it until you master web applications and/or desktop applications.
As I understand it, a web component developer creates java widgets that produce some visual image with basic functionality associated with it. For example, an html button. These widgets are used by other developers for the presentation layer when creating a web application or desktop application. I'm not sure about this definition since I never messed with web component development. I suggest you keep way from this specialized area on concentrate on web applications and/or desktop applications.
You can consider application development as devided into two general categories. Web development and Desktop development (there are others). Web development is further broken down into browser based applications and mobile device applications. I suspect their are more jobs in web development than desktop development. I therefore suggest you concentrate on browder based web development (just my opinion). However, each has their advantages and disadvantages over each other, depending on the task at hand(http://stackoverflow.com/questions/905365/desktop-development-versus-web-development)

Difference between Web Service URL and Report Manager URL

What is the difference between Web Service URL and Report Manager URL in Reporting Service configuration manager in SQl Server 2008 Reporting Setrvices

Another way to put it is the Web Service URL is just that, its used for services that are connecting to issue API calls. The Report Manager URL is the nice GUI that users should use. If you click the links, you should see the difference. I
am sure you have likely done that, but functionally one is for programmatic purposes and the other to be the front end graphical user interface.
Sometimes pictures help as well...
