Implementing several web-methods in one BPEL process

Hi
We are trying to implement an integration system with help of BPEL PM, which must provide its interface for another system as a single web-service with different web-methods (operations).
By now we were able to provide only one operation per web-service, as default BPEL behavior.
How is it possible to make a single web service "entry point" to our different BPEL processes as a web-service with different methods?
WBR, Serg.

You must start the (async) process with a pick-activity (not the default receive), and check it to Create Instance.
I just made some test-processes (soon to be more like production), so my finding are not quite mature, but here they are:
You now need to add your flavour of operations (which I assume have to be async, I've not tested sync). The operations are simply added to the process wsdl-file, typically within the existing portType.
To start with I would suggest that you use the same portType and the same message name for all operations.
You soon discover the need for separate responses as well, again its designing it and code the wsdl-file.
When you get going you can try to differentiate the message, it's all about coding the wsdl-file.
Adding portTypes looks a bit more complex, but it seems to work (but does it do you any good?).
If you add portTypes, remember to add a plnk:partnerLinkType as well.
So: Multi-operation BPEL WS here we come!

Trying to throw fault from one BPEL process to another

We are trying to throw a fault from one BPEL process to another and apparently are experiencing a common problem. That is, the invoking process times out and never receives the fault.
Likely a beginner's mistake is at fault (pun intended).
Below are samples of a simple "Hello World" process that tries to throw the fault.

Thanks very much for this answer. It was right on.
You wanted to know "how (I) get on". Funny you should ask. Believe it or not, I had figured out the problem on my own just about the time you were posting your reply (of course, this is a bit too convenient. No one will ever believe me).
But the answer leads to another question. What is the Throw activity for, if not to throw an error to the calling process? Is it only used to throw within scope of the process its self?
I am probably biased by the Java world I am coming from, but Throw feels like it should terminate the process (without side effects like a big red mark in the console) bubble up the fault to the calling process who can catch it (if so desired). Using the reply we must explicitly Terminate (which includes that unsightly red mark).
Is there any way to get this behavior from the Throw, or should we just reprogram the "wetware" and learn a new paradigm?
Is there any way to end a process without marking it with a red flag that suggests something went wrong?

Error creating web service proxy for bpel process in jdev 10.1.3

Hi,
I am trying to create a web service proxy in Jdeveloper 10.1.3, and get the following error:
Element type "fault" is missing required attribute "name"
I have created a fault on one of the operations, and in the .wsdl file there is a name attribute:
<operation name="process">
<fault name="TestError" message="client:TestErrorMessage"/>
</operation>
The fault definition in the .wsdl obtained from the process when you access it over http is somewhat different:
<fault>
<soap:fault name="TestError" use="literal" encodingStyle="" />
</fault>
Any ideas how to workaround this problem?

Using a Java Web Service in a BPEL Process

Hello.
I am newie with Oracle Soa Suite and BPEL process and i have problems. I have developed a Java Web Service, first developing the Java Class and then using the wizard to create a Java Web Service.
Now i want to develope a BPEL Process that use this Java Web Service. I have tried it with the component Partnert Link from de palette and looking for the java web service wsdl file. I have tried it with the component Java Web Service from the palette. In both of them, it happens the same, it appears erros looking for the wsdl or looking for something that the wsdl use. If someone could try it. Its easy. Create a Java class with one simple method. Create A java web service with the wizard. Then create a BPEL process and try to use it with a partner link.
I have been trying it one week...
Thank you in advance.

Hi
You can use a java web service to publish a Web service from a Java class.
A wizard creates the WSDL document and deployment files needed to publish your code as a Web service. After you select the class and methods you want to publish, the wizard generates deployment descriptors, a JAX-RPC mapping file, and a WSDL document that can be deployed to an application server.
You can refer : \bpel\samples\tutorials\102.InvokingProcesses\ws sample to invoke a WS using JAX-RPC Call.
Hope that helps!
Cheers

Two FTPAdapters triggers one BPEL-Process in Cluster

I have defined two ftp-adapters getting two different csv-files (different file structures) of the ftp-server. These ftp-adapters triggering a bpel-process starting with a pick-activity containing two onmessage-branches. In the first onmessage-branch there is a transformation transforming format A into a common format. In the second onmessage-branch there is a transformation transforming format B into a common format. With this common format some other actions are processed (not relevant for this problem).
Because i have a clustered environment (cluster of two soa-suite installations 10.1.3.1) i want only one clusternode triggering my bpel-process. so i set the property clusterGroupId of the activationAgent inside of the bpel.xml. Because i have two triggering ftp-adapters i defined two different clusterGroupIds to prevent to have a influence between this two ftp-adapters.
The problem is that the application-server now is logging every second the following warning and i don't know if this is a problem or not. both ftp-adapter works fine but i think it will not work in cluster.

I have also tried to use only one clusterGroupId but if i do so only one ftp-adapter is initiating my bpel-process. so why does this usecase does not work with using one clusterGroupId???

How to use multiple WSDL operations in One BPEL process Recieve Activity ?

Is there anyway to attach multiple WSDL operations with a Single BPEL process ? How ?

Thanks Melvin for your quick respond.
When I create a BPEL process, It asks me to give the XSD as an Input. When I import the XSD it asks me to select an operation not more than one. Let suppose I select addRequest and finish the wizard.
Now what I can see, It create Recieve activity with an Input msg of Add operation. Well what I understand from your statement is that, I remove the recieve activity and put the Pick activity.
Now my question is How to mention the other operations like update and delete ? And how to test them ?? The link provided by you is just tell me what Pick activity can do for me, But its not telling me how to use it ?? and how the give the operation to it. Where should I need to change in the BPEL ???

How to implement a FTP Adaptor in a BPEL Process

Hi
I have a requirement to create a FTP Adaptor and that adaptor should get a file from one of the unix direcotries.I have given the user name , passwd and host name in the oc4j_ra.xml and created a bpel process to get the file from the unix directory.But that processed faulted with the following error.

While the Oracle SOA Suite is running; it runs as a specific user; mostly 'oracle' on unix systems. This means that under this user it access the FTP adapter. What is you oc4j-ra.xml look like? Are you able to connect from this user on the server to you ftp-account?

Invoking Asynchronous Web Service from BPEL Process

Hi,
I have been working on the BPEL Process Manager for some time and now facing problem in invoking asynchronous web service from a BPEL Process. I have implemented a web service in Java using Axis but wasn't able to invoke it.
I have gone through all the meterial available on this site but couldn't get any great help.
Can some one help me in resolving this issue. A pointer to any example or sample material/tutorial will be appreciated.
thanks
Farooq

I do the same thing.
Take wsdl from axis and save it somewhere.
Then you can create a standard project in Oracle BPEL PM. Create partnerlink, give a name and click on first icon to take your wsdl. It will add some needed code, you answer always yes. Then you can create receive, assign, invoke, assign and callback or similar and deploy it.
Try it through BPEL Console...

I am trying to set this map data using java code ,

          AppdataDefImplWS appData1 = new AppdataDefImplWS();
          appData1.setName("Project");
          appData1.setType(pType);
          appData1.setMaxSize(400);
          appData1.setLOB(false);
     appData1.setDefaultValue("Project Default value");
          procADMap1.put(appData1.getName(), appData1);
          setVariableData("request","createNs","/createNs/namespaceData/appdataDef",procADMap1);
Then I am passing request object to the method which I want to invoke from bpel process.
I am able to deploy the application but when I do post message I am getting following exception,

Is there any other way to handle Map type in bpel process?
Thanks in advance,

Thanks for the quick reply.Actually the web service is already deployed on the server.What I want to do is use existing wsdl file of the deployed web service and invoke the method of the same using oracle PM.
If I remove element which uses apachesoap:Map type it just works fine also I am getting the complex object returned by the web service method.But when I try to set appDataDef which is of type apachesoap:Map(Axis conversion for java.util.Map and it uses namespace xmlns:apachesoap="http://xml.apache.org/xml-soap") I am getting the error.
Can you give me some direction to use this exising wsdl file to set map object or it is not possible.

BPEL process web service security issue

Hi guys,
I could use a web service based on BPEL process from local machine, but when I am calling the same service from one of the client machines i get following type of error
WARNING: Unable to connect to URL: http://server1:7777/orabpel/default/SendTransfer/1.0 due to java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: server1:
23:14:16 HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed
any help is appreciated

In your service url http://server1:7777/orabpel/default/SendTransfer/1.0 , the "server1" should be a proper IP address recognized over your network. Otherwise you can add this name with corresponding IP address in hosts file entry.

Multiple BPEL Process Managers in one environment?

Hi,
I'm quite new to the Oracle SOA product line, so please be gentle when my question doesn't make sense.
I’m in the process of designing a new enterprise architecture based on service orientation. I’m looking at the Oracle SOA Suite software to get a better understanding of what things will look like when getting to the actual implementation.
Some internal projects are moving fast, so I’m trying to get an understanding on how things will work out in the future. One case has my current attention, related to the BPEL Process Manager.
A 3rd party vender is offering a specific solution which is using or based on the BPEL Process Manager. This solution can be purchased as a black-box. From the perspective of my new architecture I would like to purchase the SOA suite as a whole. New developments will most likely be using the BPEL Process Manager for orchestration. But when purchasing the black-box application, the environment will be extended with an extra BPEL Process Manager. My first thought is to try and incorporate the BPEL processes from the 3rd party vendor onto one single BPEL Process Manager. But I also think two BPEL Process Managers can have advantages.
I’m not sure how to go forward with this. How should I handle this? Is it common to have multiple BPEL Process Managers in one environment or should I pursue maximum integration and only go for one BPEL Process Manager?

Hi,
We have similar situation at my current client site and we are going with two seperate BPEL PM installs for various reasons. One of the main driver in our case is conflicting in timelines of two seperate projects.
But my suggestion is to go with single enterprise install if that's not breaking the 3rd-party vendor supporting contracts. This has obviously benefits of redecued infrastructure/administrative and other related costs. How many processes does the vendor has as part of their solution? If they are handful you know it doesn't justify having seperate environments.
On the otherhand having two seperate installs isn't bad either depending on how big or small your SOA service/process orchestration footprint is. We don't have complete handle on the performance/scalability aspects of BPEL PM based on number of processes deployed. But as you can see that may be one of drivers to have redundancy in BPEL PM servers.
End of the day there is no clear cut answer. If you have funding and resources, go with two seperate instances. But from architectural perspective better to have single install with clustering for better performance/scalability.

How to implement runtime monitor for Netbeans BPEL process?

Hi,
I wish to implement a runtime monitor for a BPEL process. I want the monitoring program to let user interactions as well as display qualitative attributes (performances) of each member web service.
Could someone give me a direction or helpful tools in Net-beans environment? Any help is highly appreciated.

Hi,
I will provide a little specification about the concepts to remove some confusion.
This mailing list is about JBI the specification. Not about any Sun product.
I suggest we take subsequent discussion to the users@openesb mailing list.
https://open-esb.dev.java.net/MailingLists.html
- OpenESB is the product which includes a BPEL Runtime Engine.
http://wiki.open-esb.java.net/
http://wiki.open-esb.java.net/Wiki.jsp?page=BPELSE
- Glassfish (the appserver) contains some of the core OpenESB pieces. Which is why you see the BPEL engine without installing openesb.
- NetBeans has plugins to develop artefacts for OpenESB components. This includes a BPEL editor.
- Sometimes you get pieces of OpenESB development tools and runtime tools in Glassfish and NetBeans without installing OpenESB.
- This causes confusion for many people. Including yourself.
Although you are developing and running in NetBeans and Glassfish, you are really using the OpenESB BPEL engine.
To answer your question, yes it is possible to do what you want.
This links I provided previously show how to monitor the openesb bpel engine. This is what you are using.

Invoking Web Service with PKI Authentication from BPEL process

Hello --
I am trying to test calling a Web service utilizing PKI-based authentication from BPEL running under the 10.1.2.0.2 Process Manager. When I access the service from a browser I am prompted for Username and Password the first time. When I attempt to access it from BPEL I receive this error:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: No trusted certificate found
Is it possible to access this service from BPEL in 10.1.2.0.2? How can I pass the service the required credentials?
Thank you for your time,
Paul Camann

I've gotten past the original error by importing the security certificate of the Web service into my keystore/truststore. I'm also running the process on SOA 10.1.3.1.0. Now when I invoke the Web service from the BPEL process I get this error:
exception on JaxRpc invoke: HTTP transport error:
javax.xml.soap.SOAPException: java.security.PrivilegedActionException:
javax.xml.soap.SOAPException: Bad response: 403 Forbidden
I've tried passing the credentials every way I can -- partner link properties, Oracle Web Services Manager, whatever -- and still get the same error. I would expect to see a 401 error for problems with credentials, not a 403.
Any suggestions?
Thanks for your time.

Integrate Multiple BPEL Process into one project

Hi,
Can anyone help for the following problem?
We created different BPEL process.One bpel process calls the another bpel process internally .
EX:
process1,process2 and process3.
In side process1, I will call process2 and process3.
I want to integrate all 3 process into one.
Can anyone help how can i do this.
Thanks in advance.
Thanks,
Bharath

Can't you create a new process, copy everything between the main-scopes of the other processes to the new process (skip some of the receives and callbacks so you have 1 receive and 1 callback left), copy all the variables, namespaces, xsl mappings, and try again.
it's more a bit of 'trial and error' and see what's left.
Hope you can use this a bit.
