BPEL and BPEL extensionS

I went through BPEL specification in which BPEL extensions for executables and business protocols are also described.
Can anybody tell me how BPEL extension are different from BPEL. I am getting preliminary expression that BPEL extensions lack something what BPEL has.
Kimdly clarify these two.
THAT WOULD BE OF GREAT HELP FOR ME

This functionlaity is part of the stadard, in other words - you can wrtie your own extensions through this feature, and allowed to do so .. BUT it is not a must to support these (hand implemented) functions from a vendor perspective - the extension feature has to be supported ..
Other things such as wsdl use this too (e.g. a partnerlink is based on wsdl extension)

Jdeveloper with BPEL and OA Extension.

Hi,
Can someone point me to the right download and version of JDeveloper for BPEL and OA Extensions together.
Thanks,
--KC.

Yes,
You need to have separate versions. Check the metalink Note 416708.1 - How to find the correct version of JDeveloper to use with eBusiness Suite 11i or Release 12.
For BPEL related dependency, check the help docs of process manager installed on your application server.

Trying to add new elemwent to BPEL, and it is now having binding error

I have a BPEL service that calls a PL SQL procedure. I have added a new element to the BPEL called quote_cart_line.
All I had to the BPEL to accomplish this was edit 3 files -
Async_Invoke_Import_Model.xsd (Source)
<element name="orig_sys_line_ref" type="integer" minOccurs="1" nillable="true"/>
 <element name="quote_cart_line" minOccurs="1" nillable="true" type="integer"/>
 </sequence>
.....APPS_NI_MODEL_IMPORT_UTIL_IMPORT_SELECTIONS.xsd (Target)
<element name="ORIG_SYS_LINE_REF" type="decimal" db:type="NUMBER" minOccurs="0" nillable="true"/>
 <element name="QUOTE_CART_LINE" type="decimal" db:type="NUMBER" minOccurs="0" nillable="true"/>
 </sequence>
.....Transform_NIE_Inputs.xsl (Transforming from Source to Target)
<ns1:orig_sys_line_ref>
 <xsl:value-of select="/ns1:Async_Invoke_Import_ModelProcessRequest/ns1:import_line/ns1:orig_sys_line_ref"/>
 </ns1:orig_sys_line_ref>
 <ns1:quote_cart_line>
 <xsl:value-of select="/ns1:Async_Invoke_Import_ModelProcessRequest/ns1:import_line/ns1:quote_cart_line"/>
 </ns1:quote_cart_line>
 </ns1:import_line>
.....I have done this to two other BPELs and they work fine. (1st BPEL calls the second BPEL passing this new element, which then passes it to this BPEL I am having trouble with, which then should be binding it to a PL SQL type)
So this BPEL calls a PL SQL procedure, binding the elements from the BPEL to a PL SQL type (ni_model_import_line). So I edited the PL SQL type to accept this new parameter:
orig_sys_header_ref NUMBER,
 quote_cart_line NUMBER,
 CONSTRUCTOR FUNCTION ni_model_import_line(p_part_number IN VARCHAR2,
MEMBER PROCEDURE add_orig_sys_header_ref(p_org_sys_header_ref IN NUMBER),
 MEMBER PROCEDURE add_quote_cart_line(p_quote_cart_line IN NUMBER)
MEMBER PROCEDURE add_quote_cart_line(p_quote_cart_line IN NUMBER) IS
BEGIN
 quote_cart_line := p_quote_cart_line;
END add_quote_cart_line;
END;
.....I invoke all of this, and the new element gets populated in 3 different BPELs, including this one I explained here. But when it comes time to call the PL SQL I am now getting an error:
<fault>
-<bpelFault>
<faultType>0</faultType>

</fault>This doesnt happen if I remove the references to this new element and try again, so it obviously is a problem with the element, but I have no idea what it is. It works fine when going from BPEL to BPEL, but as soon as the process tries to call the PL SQL procedure this happens. It is even more frustrating because I have done this exactly before adding another element, and it worked fine...
Any ideas or tips please?

Edited by: 849655 on Aug 9, 2011 2:36 PM

So is there any further info I can provide or anything like that? I am still no closer to solving this it appears...
This makes no sense to me. I have edited these BPELs in this manner twice before and never had problems.
I have 3 bpels. I added the new element to each of them.
BPEL1 - calls some PL SQL and also passess the elements to the next BPEL (BPEL2)
BPEL2 - passes the elements to BPEL 3
BPEL3 - Calls PL SQL in exactly the same way as BPEL1
however, where BPEL 1 is functioning fine, BPEL3 is resulting in the error above. So frustrating, because BPEL3 works exactly like BPEL1, there is no reason it shouldn't be working. The elements are the same order as the PL SQL type and procedure it is mapping to, so that isn't the problem

Oracle Workflow - Statement of Direction and BPEL

Hi,
I am starting to study Oracle BPEL and other people at my company are studying Oracle Workflow.
Recently I found the following article at the OTN, regarding the Statement of Direction of Oracle Workflow:
http://www.oracle.com/technology/products/ias/workflow/workflow_sod.html
It finishes saying:
"As Oracle BPEL Process Manager provides out-of-the-box features for building human-based workflows, rules-based process automation, and integration style business processes, further development on OW4J will not continue and OW4J will not be released.
Any new or existing customers who wish to build business processes in the middle tier are recommended to use Oracle BPEL Process Manager."
So my question is: Does Oracle BPEL provides (or will provide) all the functionality implemented in Oracle Workflow ? If not what are the main differences ?
I will be waiting for your thoughts
Thanks,
Claudio.

Site mentioned above is an internal site. External site is http://otn.oracle.com/bpel
I think the above highlighted SOD is about Oracle initiative to re-write current pl/sql based Workflow engine in Java so that it can ported to middle-tier. Since the acuisition of Collaxa they seems to be dumped that idea and positioning Oracle BPEL as the middle-tier process orchestration (BPM) solution.
Having said that let me take a shot at comparing Oracle Workflow and BPEL products....
Oracle Workflow
* No way getting dropped as Oracle EBS has huge investments in it
* Oracle Fusion Applications has plans to use the Oracle Workflow BES functionality extensively
* Good for modeling business processes within a single DB/application instances. It's possible to integrate with external apps but not an elegant solution
* Web Services can be a functional activity with in the work flow but again not an elegant solution. Requires DB java, queues and a listener
* Doensn't provide sophisticated modeling artifacts like TaskManager, Faults, sensors etc out of the box. It's possible to build your own library.
* Better performanent if the entire process interaction is within a single instance like Oracle EBS account generators, approval flows etc.
* Based on proprietary technology
Oracle BPEL
* Based on standards like BPEL, WSDL and WSIF
* What ever you can do in workflow can be done in BPEL but not the otherway round
* Has adapters to interact with various transports like JDBC, AQ, JMS, JCA, HTTP. That means integration with existing workflows is very easy
* Interation with Oracle AQs seem to be trivial as there is a native JCA based adapter for it
* You may get performance hit because of the multiple connection points. You may be loosing performance but gaining in flexibility
Overall Oracle BPEL seems to be the way to go if your business process involves multiple applications.

Passing value from ADF to BPEL, and to PL/SQL procedure

1. I have created BPEL which take 2 inputs and concatenate them.
2. have created a PL/SQL procedure for invoking this BPEL( working fine).
Now i need to create a simple ADF page which contain 2 text box, 2 for input and 1 for result(concatenate), this will take 2 inputs and send them into BPEL, this will invoke the BPEL process and perform the necessary concatenate function...
in addition to this, i am passing code into PL/SQL procedure ...
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body xmlns:ns1="http://xmlns.oracle.com/OrderImportDemo">
<ns1:InputRequest>
<ns1:FirstName>abcdef</ns1:FirstName>
<ns1:LastName>aaaaaa</ns1:LastName>
</ns1:InputRequest>
</soap:Body>
</soap:Envelope>';
this code will take vaule from BPEL and run properly.
can you please help me,

thanks for help, but the problem is diff.
i don't have any schema, what i want i need to create a adf page that will contain 3 tent field, 2 for input and 1 for output. when i will enter 2 input field and click on ok button, this will invoke BPEL, BPEL will take these 2 inputs and do the concat on this and send back to adf with result.

can you please help me,

Three simple steps you need to do :
1) Generate proxy for your bpel process in Jdeveloper.
2)Create simple ADF page with 2 input for taking value and a input for showing the result and one command button.
3) In backing bean on command button action, get value from two inputs, pass the in the proxy service and update the the the third input with the result of service.

How To : Call External Webservice from BPEL and pass SOAP Message to the WS

Hello All-
Greetings to all BPEL gurus. I am currently facing difficulties in calling an External Webservice from my BPEL Process and passing SOAP Message to it. The details are below:
1. The BPEL process, using database polling feature of DB Adapter, will get the records from the database.
2. Transform the message
3. Call the External Webservice and pass the transformed message as the input to it. However the Webservice expects the BPEL process to send SOAP headers in the input message.
I am struggling on how to put the transformed message within a SOAP envelope in the BPEL process.
If anyone had similar requirements and have successfully been able to send SOAP messages from BPEL process to an external webservice, kindly let me know.
Also if there is some kind of documentation or any link in the forum that I can refer, please let me know that as well.
I am new to Webservice integration using BPEL and would really appreciate your help.
Thanks In Advance

Dibya

Hi Dharmendra,
I am trying to send a SOAP message from my BPEL process to a web service. I have a complete SOAP message in a complex variable defined in the wsdl for the partnerlink (web service). My problem is that when I invoke the partnerlink it fails even though the content shown in the BPEL console looks valid.
I have set up obtunnel to see what I am actually sending out from BPEL. You mention that BPEL creates the SOAP envelope automatically.
I think that my problem is a result of this automatic SOAP envelope that BPEL is creating. Do you know if there is a way to turn it off?
This is what I see in the TCP monitor, please note the double SOAP env:Body:
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <env:Body> <RCMR_IN000002NR01 xmlns="urn:hl7-org:v3" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsa="http://www.w3.org/2005/08/addressing" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd">

Any help is appreciated.

Should have mentioned. I am using BPEL 10.1.3.4

I have opened a new thread for this question so as to not confuse the issue more than necessary.
How many SOAP envelopes do you really need?

Performance tuning in BPEL and ESB

Hi,
Any one can tell me how to do Performance tuning in BPEL and ESB.
How to create WEB SERVICES in BPEL

Hi',
Performance tuning in BPEL and ESB.
***This is very big topic I can give you 2 points here
In BPEL we should avoid the use of duplicate variable, the best way to do this is, when ever we are creating a new variable
we need to ask can we reuse variable from inside the process, example when creating the input/output variable in Invoke activity
we need to check if we can use some existing variable instead of creating new.
All the DB related operation should be performed in 1 single composite.
How to create WEB SERVICES in BPEL
Not sure what you want to ask here, as BPEL is itself a webservice.

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

Purchase Order to Purchase Order using BPEL and/or XML Gateway

Hi,
Is there a way to do create a duplicate Purchase Order in another instance using BPEL and/or XML Gateway? We're looking to do A2A transactions, namely duplicating data from one instance to another (of course the functional setups would have to be the same). Thanks!!

this is the perfect usace for the upcoming ESB (shuffling data with transforming from A to B) - but this can be done with BPEL too .. there are some solutions to this
1) on a database level (db to db)
2) having events setup'ed in the master instance, that fire a process that get's the data
3) and then using the functions from iRep

XSLT and XQuery recommendation for BPEL and OSB

Hi,
1. Why is XQuery recommeded for OSB and XSLT for BPEL. Are there any specific performance optimization reason behind this.
2. Apart from OSB and BPEL, both XSLT and XQuery has xml transformation options and creating HTML. What is the difference between these two.
Thanks in advance!

you can create the graphical view of Xquery in Eclipse but not for XSLT
Xquery is much faster than XSLT in OSB.
Through XSLT however you can achieve more complex transformation.
OSB has its historic origins in BEA Aqalogic stable and so Xquery was widely used used even though XSLT is supported. It is a matter of choice(your standards in your organization,your developer skillsets,your re-usable libraries etc )
In Jdeveloper you can develop xslt in graphical mode though and attain complex transformation

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

BPM and BPEL process differentiaition.

Hi All,
Can any one shed some light on below points
1) How is a BPM process different from BPEL process.
2) Can i achieve every thing in BPM process that i can achieve in BPEL process.
3) Also when BPEL process is available why has Oracle introduced BPM process.
Thanks
Parker.

Hi,
You can refer the following short PDF about the key differences between BPEL and BPM and when would be the right strategy to use either BPEL or BPM.

What is the main difference between BPEL and ESB

Hi all,
I am making use ESB in my application .Where the my client application calls ESB and inturn the ESB calls the BPEL process .
I want to know the differences between BPEL and ESB,I came to know that ESB can do messaging and routing ,where my BPEL process can also do the same thing .
I came to know form a vendor that ESB is used for connecting to multiple end points ,where as my BPEL process can also do this.
SO what is main purpose of using ESB ?

Forcing HTTP comm between BPEL and ESB

Hi all,
for demo purposes, I'd like to disable the internal and non-HTTP communication between BPEL and ESB when both are deployed on same OC4J container.
I do not want to modify any WSDL but, if possible, disable somehow such internal communication. AFAIK, there was a property named "optSoapShortcut" in 10.1.2 but it no longer exists in 10.1.3.
Any clues?
TIA

Hi.
Sometime ago I tried to work with a BPEL property named preferredBindings, but it didn't work at all.
WSM Gateway is bypassed when WSDL has SOAP and JCA binding. How to choose??
I don't know if I came across a bug, but in theory I believe this is something like this:
To indicate you want ESB binding:
<property name="preferredBindings">http://www.oracle.com/esb/</property>
To indicate you want SOAP binding (I'm not sure):
<property name="preferredBindings">http://schemas.xmlsoap.org/wsdl/soap/</property>
Please let me know about your results.
Regards.
