How to invoke TaskService updateTask from within BPEL Process

Hi
I have to call the updateTask method defined within TaskService to update the BPEL payload. I initiate the Task in the same BPEL process but I want to update the payload somewhere down in the same BPEL process. Can someone assist me in finding out how I should do that without writing Java code? I want to know which task values I need to set before using the invoke activity and assigning the updateTask method to it.

Invoking ODI Scenario from a BPEL process - Resolved

I new to Oracle products.
I am exploring Oracle Data Integrator tool.
I would like to call ODI scenario from a BPEL process.
I created a scenario in ODI, I have SOA suite10.1.3.3 installed in my machine.
In some portal I have read that, we need to deploy apache axis to Oracle App server and then deploy the ODI public web service to axis. This public web service facilitates us to call scenario from partner link.
Following are my questions:
1) I guess Oracle App server acts as webservice container too. Why should I use apache axis here?
2)If axis must be used, please let me know how to deploy it to OAS.
If axis is not required, please guide me how to deploy public web service to OAS.
Thanks!!

Unable to invoke a EJB from a BPEL process

I am unable to invoke a EJB from a BPEL process. Whenever I try to test it from the oracle EM, I get the below exception. I am using WebLogic 10.3.3, SOA suite 11.1.1.3 and JDev 11.1.1.3 .
This is what I see from the EM....
Non Recoverable System Fault :
javaInterface attribute for the binding is missing or the inteface class is not available.
Below is a part of the stack trace from the soa server log…

Any help would be greatly appreciated.

I haven't tried from a BPEL process, but I have had success (as in Lucas's blogs) of using services and references as EJB Java Interface. This is with EJB java interfaces solely of base types (i.e. String foo(String s)).
At high level here's what I have noted so far:
1. Per Lucas's blog, @javaInterface is not being added to the ejb.binding automatically but it's not clear to me when this is and is not required given that interface.java is specified for the reference or service. Would interface.java and @javaInterface ever be different? I've been adding @javaInterface manually anyways since Lucas is a smart guy and I'd rather avoid errors. :-)
2. Dropping an EJB interface jar in SCA-INF/lib works, but I've had the problem that the JDeveloper SOA Plugin doesn't see those classes until I stop and restart JDeveloper. Until then, I'm confronted with the java->wsdl mapping error. I was sort of primed to figure this one out since I ran into similar issues with SOA SpringBean components.
3. Dropping EJB interface source in SCA-INF/src is more reliable, because then I can build the project (i.e. create SCA-INF/classes) and the JDeveloper SOA Plugin seems to resolve these brand new classes immediately.
4. I've tried to invoke an EJB java-interface reference with a slightly complicated java interface (a class parameter with some fields, one of which is an array of another class). The auto-generated WSDL doesn't look exactly right to me (but I'm new to JAXB). Mediator maps to it just fine and the project compiles and deploys normally but fails at runtime. I have not researched in depth. It's not clear to me from the documentation and release notes whether I should expect for it to work, or whether I should expect to have to create my own JAXB mapping. If the latter, I really need a good example!

How to invoke an OSB service from a BPEL process

I need help, to figure out how to invoke an OSB proxy service from a BPEL process.
I found a blog which exactly does that; but I am unable to get it to work. I get the following error on my BPEL console. We are on OSB10gR3 and SOA 10134.
"com.bea.wli.sb.transports.TransportException: Unknown error while processing message for service ProxyService DWIntegrations/ProxyService/PeopleServiceBus"
Any help will be greatly appreciated.
Regards,
BP

It really comes down to the proxy service on the OSB. Is it invoked by a WSDL? If so you should be able to take the endpoint defined in the proxy service messaging configuration and use that URL. You also need to use the sb transport type.
Can you also post the blog you used, then we can put it into context.
also have a look at this link.

How to invoke a custom adapter from a BPEL process

Hi guys,
I've implemented a custom outbound adapter and deployed successfully on Weblogic V.10.3.4.
My current installation also consists of Oracle SOA Suite 11g / JDeveloper 11g (11.1.1.4.0)
In the Weblogic administrator's console,
*1.* I navigated to:
Summary of Deployments -> AdapterName -> Configuration -> Outbound Connection Pools
*2.* Selected: javax.resource.cci.ConnectionFactory and added new JNDI name for Outbound Connection Instance: "*eis/HelloWorld*"
My task is to invoke the custom adapter from a BPEL process.
I altered the customAdapter-config.xml so as to be able to use custom adapter wizard from JDeveloper's "Service Adapters" palette,
and fullfilled the custom adapter wizard's fields accordingly. The 3rd step of the wizard requires Connection Information.
I added: "*eis/HelloWorld*" in the "*Connection Factory Location*" field.
Deployed BPEL process successfully, but testing failed due to binding.jca-12510 error:
"The JCA Binding Component was unable to establish an outbound JCA CCI connection due to the following issue: BINDING.JCA-12510 JCA Resource Adapter location error. Unable to locate the JCA Resource Adapter via .jca binding file element <connection-factory/> The JCA Binding Component is unable to startup the Resource Adapter specified in the <connection-factory/> element: location='eis/HelloWorld'. The reason for this is most likely that either 1) the Resource Adapters RAR file has not been deployed successfully to the WebLogic Application server or 2) the '<jndi-name>' element in weblogic-ra.xml has not been set to eis/HelloWorld. In the last case you will have to add a new WebLogic JCA connection factory (deploy a RAR). Please correct this and then restart the Application Server "I tried to apply (just for testing) "eis/FileAdapter" in the "Connection Factory Location" field of the custom adapter wizard,
and BPEL successfully invoked the adapter.
Any ideas ?
Thanks,
George

George, What deployment do you have this associated with?

Error while invoking ESB process from a BPEL process

Hi all
We have a requirement to call an ESB process from a BPEL process. We are using an adapter wth the ESB's WSDL url. After deploying the BPEL process, the registered ESB is getting called for most values while suddenly some values return the followign error
*"exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: Connection reset"*
The catch here is, if we re-run the process with the same values again, the ESB is called successfully! How is it possible for a process to error out and run normally for the same inputs ?
What could be the possible fix for this? I am thankful for any inputs on this.
Vijay

Hi Vijay,
This is a bug and you can refer the metalink note:
"Applying Patch 7445876 Results in Error "java.lang.NullPointerException". [ID 942575.1]" for reference.
Also you can refer the following link:

Invoking JDev bpel process from Eclipse BPEL Process?

Is it possible to invoke a bpel process (with dbadapter) developed in JDev from a bpel process created in Eclipse (Designer)?

I was unsuccessful.
Scenario:
I was trying to invoke jdev bpel process (that had a database adapter to update the database) from Eclipse bpel process (since we do not have adapters in Eclipse designer).
The namespace wasn't known by Eclipse( some schema missing?) and therefore we couldn't compile it.

Invoking bpel process from another bpel process in same app server

Hi,
When I invoke a bpel process from another bpel process in the same oracle AS
1. Is it a SOAP call or is there any optimization?
2. If there is some optimization where can I configure this?
3. Is there any similar optimizations if I invoke a bpel process from a
java application deployed in the same server? If so can you please provide
a sample?
Thanks for your help
Raj

By default the BPEL 10.1.2, it will do a local call to the process. It will not execute a SOAP request, no network access is done.
It can be configured at domain level:
Parameter: optSoapShortcut (SOAP local optimization)
Turns on "short-cut" for local SOAP request; local SOAP calls are normally done via an internal call instead of sending a message through the SOAP stack.
The default behavior for the engine is to optimize all. To disable optimization specify a value other than "true" or "yes".

Invoking Session EJB (with WSIF binding) from a BPEL process

Hi,
I am invoking a stateless session bean from a bpel process. The bpel process is throwing:
Failed to lookup EJB home using JNDI name 'ejb/visilient/BPELHelper'; nested exception is:
java.lang.NullPointerException
I can see the ejb jndi name under 'default' app.
Any ideas?
TIA

It is a lovely sample... However, it doesn't cover Complex Types and Exception handling. It would be nice if each example was thorough. Would be a great help.
What I was hoping to achieve is this:
1) Have an EJB deployed
2) Use WSIF for BPEL Processes.
3) Use Web Service interface for AJAX calls etc.
I was hoping that this would be the exact code base and that only a single EJB would be deployed.
So far, it looks like JDeveloper will only support Java WSIF bindings. No EJB Bindings. It also looks like JAXRPC is the best supported WS interface. With that in mind, it deploys a seperate subset of the EJB. Thus causing two seperate deployments. I am working on trying all this out over the next couple days. See where I get.
Anyways, do you have any recommendation for accomplishing what I am wanting to do? 1 deployed EJB, with a WS interface and allowing WSIF bindings. Any other references for me to look at? Should I not be thinking about using JDeveloper for any of the WSDL generation and do all this manually for now?
Thanks,
BradW

How to invoke crystal reports from Oracle forms 11g R2 along with passing p

How to invoke crystal reports from Oracle forms 11g R2 along with passing parameter to it.
how to pass parameters to crystal report, please help.

how to pass parameters to crystal report, please help.This would entirely depend on crystal reports and you might find informations on crystal reports related communities more likely...I for one have seen crystal reports the last time about 12 years ago. And even back then I simply acknowledged it's existence instead of working with it.
Maybe crystal reports can be invoked via a URL call which would make it simple as you'd need simply build an URL and show the report using web.show_document. But that's pure speculation. Also you might not be the first with this requirement, so the solution to your problem might be right under your nose and just a little google search away ;)

How can we call a OSB proxy service from a BPEL process?

Hi,
I want to call a OSB proxy service from a BPEL process. Can you please explain me the procedure?

Get the wsdl of the OSB proxy service and create webservice parnerlink in BPEL based on this wsdl to invoke the service
To form the wsdl url, copy the Endpoint URI configured to the proxy service(just click on the proxy service in the console) from the sbconsole - /ATHGPUM_GlidePathService/ProxyService/ATHGPUM_GlidePathProxyService
Pre append <<protocol://OSB Hostname:OSB Port>> - http://localhost:8000/ and post append with ?WSDL
The final WSDL url look like - http://localhost:8000/ATHGPUM_GlidePathService/ProxyService/ATHGPUM_GlidePathProxyService?WSDL
