ESB to BPEL request in jdev

Hi,
Situation:
An external system sends a request to the ESB that I am going to create. This ESB transforms the incoming request to a different format and then sends the transformed request to the BPEL (need to create). The BPEL invokes an external system
My Question is "How do I start with this?".
I have input XSD and output XSD. I am having hard time figurings out which service to create first (ESB or BPEL?). If I start with BPEL (synchronous) I need an input wsdl (from ESB) which I did not create it yet. If I start with ESB I need an target wsdl (for BPEL).
Can some please advice me on this. Your response is much appreciated.
Thanks,

Hi,
You need to see what is common between the ESB and the BPEL Process :
The interface.
So you can first :
- Create a BPEL Process whose client inputMessage respect the ESB output message XSD :
For that you need to import your XSD Schema in your bpel process (Simply copy and paste it in the 'bpel' folder of your project).
Then when you create the BPEL Process, go in the structure window, then click on Message Types, then navigate to your input message, then right click, edit the message type to have the an element which respect your XSD schema.
So now you have a BPEL process which takes in an input which respect the schema that your ESB Service sends.
You can deploy it.
- Now, create your ESB Service, and import the BPEL Process WSDL, even if it's not complete, you only need to define the interface between your components.

You need to start with BPEL. First of all you need to define your inputs and outputs. BPEL will create a WSDL based the XSDs you use.
When you create the ESB you call the BPEL process using that BPEL wsdl. It is also good practice not to use a SOAP call to the BPEL process. You can call BPEL directly so it runs in the same JCA.
To do this create a new routing rule in the routing service. click the cog at the end and select the BPEL service using the menu.
Hope this helps

What fits better to this scenario? ESB or BPEL? (SOA suite 10.1.3.1)

Hi,
Below is a sample situation which needs to be built as a set of processes/flow in ESB. Could anybody pls tell us if we are on the right track here?
a. A partner system needs to invoke one of our web services to perform an operation supported by the web service (this is a synchronous service). However the message that is generated by this partner system is not in teh same format as what is expected by our service. Which is why we have landed up trying to write an adapter in ESB which will do the transformation among other things.
b. The message sent by the partner system is received by (possibly) a router service in the ESB and it applies the necessary transformation.
c. Once transformed, this x-formed message is sent onward to our underlying web service. The response received back from the web service would also now need to be x-formed back to the format of the partner system
d. However, we could not find any mechanism of x-forming a response in ESB.
e. A workaround we can think of is to add another router service in this ESB flow, which will apply reverse transformation and then pass this reverse x-formaed message to a dummy process (possibly a BPEL) which just sets the response = request.
f. This response then gets sent back all the way to the initial partner which requested the same.
Should we really use ESB in such a situation? Or are we better of doing this in BPEL where all this is as easily possible? Frankly, we have already implemented this in BPEL (in 10.1.2) and now since ESB and BPEL are integrated in 10.1.3, as part of the migration to 10.1.3, we are exploring if we should move fully to ESB from BPEL since our process flows hardly have any business logic.
The thought process of migrating to ESB emanates from material which seems to suggest that x-formation, routing and adapters are functionality that should be utilised in ESB and only true-blue business logic needs to stay in BPEL. Since our processes are more like integration processes which only do x-formation and route to underlying web services, they seemed to be natural fits for moving to ESB to us...
Another point in consideration is that the message received from the partner system is a string which is a XML at runtime. This was not a problem in BPEL where we could use parseEscapedXML and convert to XML before working on the XML. But now in ESB....? Would this throw any spanner in the works?
Would appreciate any kind of responses on the same. Pls do revert in case further information is necessary.
With Regards....

This is a classic ESB service virtualization use case and is trivial to do req/resp with xslts in ESB. The only issue I see is the last thing you mentioned, needing parseEscapedXML which has not been made available in ESB as of yet. I can think of several workarounds for an async use case but for sync you need an intermediary to create the dom. I'll record this use case and make sure we cover it for AS11 and investigate how feasible it is for 10.1.3 patch. Thanks for the feedback.

Can't drag Service into BPEL flow in JDev 10.1.3.4 on Mac OS X 10.5.5?

Hi there - I have an issue in JDev 10.1.3.4 on the Mac. When I open a BPEL flow in JDev and begin to build a process, I can't drag/drop a service from the right hand Services palette into the flow. I noticed this when trying to bring in an Oracle Apps Adapter service, but it applies to other Services and Process Activities as well.
This is behavior that I noticed on JDev 10.1.3.3 on Mac OS X 10.5.5 but I wanted to see if it changed in 10.1.3.4 - and it hasn't. I just pulled 10.1.3.4 and am launching it from the JDev script in the downloaded folder. I have updated the Mac OS to client-side JDK, but I don't know if that's the version being used by my JDev install.
Have others noticed this problem? What specific configuration are you using? What other information can I post to make sense of this?
Thanks,
Jim

Best practice for version control B2B, ESB and BPEL

Hello,
we are setting up a new system using B2B, ESB and BPEL. The development team is more experienced working with PL/SQL, Oracle Workflow and we are worried that Jdeveloper generates changes to the source files during development and that we might have problems with the version control.
Is there any best practice for setting up version control for these systems? Do we need to take anything in particular into consideration when setting up the projects?
We are using Serena Dimensions 9.1 for version control with the add-on in Jdeveloper.
Thanks in advance!

I believe JDeveloper has a plugin for Dimensions.
I havent used it but to get it, go to tools (It may be help I don't have JDeveloper on this machine to confirm) check for updates.
If you select the thrid party check box - next, you will see an entry for dimentions.
Configure the connection and develop as you would any other project.
cheers

ESB and BPEL in different servers

Hi ,
Is there any performance based advantage when we have BPEL and ESB in different servers ?

If you seperate them, it will have impacht on the perfromance. Services are called over the network, assuming BPEL and ESB are on different servers. Otherwise they can call each other via native binding if ESB and BPEL are in the server and container.

Integrating ESB and BPEL to transmit the data

Hi,
We are integrating few sub systems like when a new employee as joined the organization we will enter those information in a HRMS system where those information will be transmitted to the ESB server where ESB should carry this message and pass it to the other sub systems like security gateway system, Coupon Mgt System , etc. In those systems we need to have a BPEL to process the employee details that is carried out by ESB. Based on the emplyee details, the BPEL process should write the business logic to provide access to various blocks in the oganization as well as provide the coupon for the user. This is the design we have comeup with. Since i am new to this. Please tell me how we can proceed with this. How we can integrate ESB and BPEL? Please provide some links or examples in how we can go about. Which will be really helpful.
Thanks.

Hi,
General idea looks good. What version are we talking about here? I'm assuming 11g... and when you say ESB I'm not sure if you are talking about OSB (ALSB) or other product, or ESB as an general idea...
Stuff to think about:
those information will be transmitted to the ESB serverHow? Will the HRMS system call a webservice? Trigger a file? Or the HRMS system has to be polled?
ESB should carry this message and pass it to the other sub systemsYou have to check the capabilities of your other systems, do they provide web service interfaces? will you need access to those systems internal databases? etc
How we can integrate ESB and BPEL?If you are talking about OSB, they integrate via web service calls

ESB vs BPEL

Last week I followed a course about the use of ESB in my organization. I noted that there were some problems understanding the difference between ESB and BPEL. In my understandings Oracle ESB is something like a way of providing several business processes to internal/external parties and BPEL is just a technology to implement a service (which can be called by the ESB). I see the 'Bus' as an interface to all the parties, making it possible to invoke services. The way or technology (eg BPEL) the actual services are actually implemented are completely transparent to the party using the services defined on the ESB.
It's just a pure theoretical question and I wonder whether someone can confirm my understanding or give a more complete explanation.
I post this because after the course, there were some questions about the use of ESB vs the use of BPEL. I mean: is there a question like: "When should I use BPEL and when should I use ESB? Like I said: I thought ESB was just a way to provide services in a more common way.
Thanks in advance,

Which is faster ESB or BPEL and why?

Hi,
Can anybody please tell me which is faster, either ESB or BPEL? I believe ESB is more faster than BPEL due to the message payload in BPEL not ESB.
It would be great if anybody can put some info on this plz.
Cheers!

You are considering only performance as the criteria for choosing between two products which have different purposes which is not the right way to go about it. Lets consider(just an assumption, might not be true) that BPEL is faster for a flow which requires simple routing/mediation to a back end service, even then you should ideally use OSB for that flow/service rather then doing it on BPEL.
If you have to consider only performance then its my understanding that OSB would be faster then BPEL for simple routing.
Architecture of both OSB and SOA Suite/BPEL is different, OSB is optimized for short running, fast and stateless services while BPEL is optimized for long running and stateful processes.

ESB vs BPEL : which one should we use

Hello All-
We need some pointers regarding the strength and weaknesses of ESB and BPEL and in which scenarios we should be using either ESB or BPEL or both.
Currently, our EDI processing system is on BPEL 10.1.2.0.2 version and the details are given below:
BPEL 10.1.2.0.2 and Oracle Integration B2B 10.1.2
BPEL is used for transformation and feeding the messages to B2B. It's also used for transaction tracking, error handling and notification. We have implemented both inbound as well as outbound EDI.
File, DB and AQ adapters are heavily used but we have seen severe performance issues under load
As part of upgrade to 10.1.3 version we are evaluating whether we can use combination of ESB (using the file adapter) and BPEL(for transformation, transaction tracking, error handling and notification) and whether it is recommended. Basically we are evaluating the option of migrating the processes to 10.1.3 version as -is or introduce ESB to reduce performance bottlenecks.
Please provide us pointers to recommneded best practices as well as any documents/case studies.
Please get back to me if you need any additional information.
Thanks in advance.

Dibya

Hi Dibya,
Oracle BPEL can be used for integration code but its not designed/optimised for it.. Oracle BPEL is a Business Process Execution Language and as such its optimised for managing and coding business processes, whereas an ESB is quite simply a highly efficient intergration product. Its principle objective is to join two different services together quickly, efficiently and bi-directional.
Specifically an ESB moves data via
Connects services via different adaptors (WebServices, FTP,File,JDBC etc) and protocols (HTTP,JMS)
Enriches and transform data using XSL & domain value mapping lookups
Routes messages based on data in the message payload and/or header
and finally and often overlooked feature is that an ESB
Virtualises services, quite simply adds a facade layer to your infrastructure...
Its also worth noting that doing integration work with Oracle ESB is not only quicker to "build" but its also quicker in its execution. I've been told by some collegues in the US that an integration process in ESB product is approx twice the speed of same process in Oracle BPEL..
So to recap
Use ESB when
You want a really low cost solution
Only need connectivity, simple transformations and routing
Use BPEL+ESB when
You need to code complex business logic
Integration with Workflow
Complex transforms potentially involving the database
Have Long running processes which may or may not be stateful.

Exploring the transaction boundaries between ESB and BPEl

Hi
I was working on how to explore the transaction boundaries between the ESB and BPEL.
How to work on these I have some confusions over in this.
Please help me.
Cheers.

Jan,
Are you sure about this ?
http://www.oracle.com/technology/products/integration/esb/files/esb-transactions-errorhandling.pdf
I'm not a die-hard at the transaction-mechanisme so some wild guessings.
If i look at this document, i can define on every routing rule the sync/async processing.
If i select on both db-adapter-routings the sync-option, and i make sure both dbadapter-connections make use of the xA properties in the datasource-properties, shouldn't this help him on his way?
I haven't tested it, so im curious what it would do, or do i miss something?

Error connecting Jdev with ESB and BPEL - caused by remote HTTP Server

Hi everyone, hopefully someone can help me with my problem.
I have 3 servers in my cluster, one straight web server, one SOA server and one J2EE server. I am trying to configure Jdev for developing SOA applications.
I was able to create the application server connection without a problem, but when I try to create the Integration server connection, I get:
Application Server: OK
BPEL Process Manager Server: FAILED
ESB Server: FAILED
With the details for the failed connections:
BPEL: java.net.ConnectException:Connection refused: connect
ESB: ESB Server connection could not be established.
Connection refused: connect
So, I know why this is happening. The ESB server doesn't have an HTTP server on it; The web server is the server for the BPELControl and the ESBControl.
So, I add the Web Server machine as an AS (it has no oc4j instance) and if I use that AS as the Integration Server, I get OK for BPEL and ESB but a failure for the Application server.
Now I know this topology must be more common than it seems, so hopefully one of you knows how I can work these problems out.
Thanks,
Jamie McLaughlin

Hello Jamie,
We are in a similar situation, as we have web-server and app-server separate. and soa suite is running on the app-server.
I got the exact same errors as you described in your note.
i am able to deploy services from jdeveloper (per your second posting) even though as & is connection entries raised those errors.
Could you let us know what approach your team is now using with respect to defining connections in jdeveloepr & deploying services? Did you get any suggestions from oracle support, or others, which helped you resolve this situation ? (even though we are able to deploy the services, the connection entry test errors are kind of annoying)
Thanks

ESB Console turns Request/Response message into One Way message

Hi folks,
have come across a strange situation and wondered if anyone else had come across this. Maybe it's fixed as part of a patch set.
I'm running SOA Suite 10.1.3.1.0 on Windows.
After I've created and deployed a Request/Response service (either RS or SOAP Invocation Service) if I go to the ESB Console and click on "Apply" in say the Definition tab, my service turns into a One Way service.
This then causes null pointer exceptions when I run my process, as you might expect.
If I redeploy from JDev and leave the "Apply" button alone I'm back in business.
Is this something that anyone else has had a problem with?

Hi.
I would recommend you to install version 10.1.3.3 of SOA Suite
http://download.oracle.com/otn/nt/ias/10133/ias_windows_x86_101330.zip
http://download.oracle.com/otn/linux/ias/10133/ias_linux_x86_101330.zip
Also, use the JDev 10.1.3.3
http://www.oracle.com/technology/software/products/jdev/htdocs/soft10133.html
They are supposed to be much more stable.
After using the new release, let us know if you still run into this problem.

Can anybody help, how to set the right permissions?

IMHO you did not solve your first problem. Because in first case you chose directly from routing service as target operation your BPEL process operation. And ESB wanted to execute that though RMI. Which has transaction support and is also faster. But your credentials were invalid. Therefore you got that exception.
After that you decided to use SOAP HTTP protocol, which is not transaction enabled and is slower :-(
In case you would like to use RMI, you have to change in your SOA Suite in this file:
<orahome>/bpel/utilities/ant-orabpel.properties
credentials for oc4jadmin user. After you update that, restart server.
And then it should work.
