[Workaround] Calling BPEL process from jspx causes DCA-40012 error on AS

Question

Hi!
I've created a DataControl for my BPEL process in my application (ADF BC 10.1.3.3).
I've created command button on my jspx page that has ActionListener binded to a backing bean method that calls commit and than my BPEL process through the bindings.
The process consists of reading some DB data, creating XML message and saving it to disk.
If I run my application from JDeveloper, everything is working fine, the file is written to desired folder. But after I deploy my application to AS 10.1.3.3 and try to call the same process, it doesn't get executed. I see this error in log files:
Exception:

I read about bug 5878326 and tried applying the patch Patch for 6404865(Base bug 5878326) in my JDeveloper (on my local machine, not on AS, since there is no JDev on the server).
But this patch doesn't solve my problems. Is there another patch for this or this behavior isn't the same as in bug 5878326?
Thanks, BB.

Hi BB,
It's Phil again.
Thanks for the follow up, especially you aren't working on this subject any more. This is indeed a bug in 10.1.3.3, but not on 10.1.3.1 Application Server. Embedded OC4J server in JDeveloper 10.1.3.3 doesn't produce this error at all. Patch for 5878326 does NOT solve this issue.
However, I have found a walk-around for this issue. Most if it has already being documented.
Oracle recommend two options to access a Web Service, by creating a Web Service Data Control or a Web Service Proxy.
See more info: http://www.oracle.com/technology/products/jdev/howtos/1013/wsadf/adfcomplexwstypes.html?_template=/ocom/print
Both approaches work on JDeveloper 10.1.3.3, but the prior option will fail on App Server 10.1.3.3 due to the bug being discussed in this thread.
For the time being, we can opt for the second option. A quick example is provided below.
- Construct a Web Service Proxy by right-click on chosen project, select New ... | Business Tier -> Web Services | Web Service Proxy, provide WSDL URL and complete the wizard. a Web Service Proxy is generated for you at (your package).proxy under Application Sources folder.
- Select this proxy, switch to Struture view, you will see a list of classes contained in the proxy. Look for a class with name (Web Service Name)Client.java. In my case, it is called __soap_getCustomerDB_getCustomerDB_pttClient.java. This class is of particular interest to you, as it provides an interface to invoke Web Service calls, in this case, getCustomerDBSelect_id(GetCustomerDBSelect_id id).
- Now create a new class, which you may extend from the example class below.
/********************** CODE BEGIN *********************************/
package oracle.srdemo.datamodel;
import java.rmi.RemoteException;
import oracle.srdemo.datamodel.proxy.__soap_getCustomerDB_getCustomerDB_pttClient;
import oracle.srdemo.datamodel.proxy.types.com.oracle.xmlns.pcbpel.adapter.db.top.getcustomerdb.GetCustomerDBSelect_id;
import oracle.srdemo.datamodel.proxy.types.com.oracle.xmlns.pcbpel.adapter.db.top.getcustomerdb.CustomerCollection;
public class WsCustomer {
__soap_getCustomerDB_getCustomerDB_pttClient myPort = null;
public WsCustomer() {
try {
myPort = new __soap_getCustomerDB_getCustomerDB_pttClient();
} catch (Exception e) {
e.printStackTrace();
* @param customerId
* @return
public CustomerCollection getCustomer(int customerId) throws RemoteException {
GetCustomerDBSelect_id id = new GetCustomerDBSelect_id();
id.setId(String.valueOf(customerId));
return myPort.getCustomerDBSelect_id(id);
/********************** CODE FINISH *********************************/
- Save the class, rebuild the project.
- Right-click on this class and select 'Create Data Control'. You should find a new Data Control named (Your Class Name)DataControl is generated on Data Control Palette.
- You can drag-and-drop available methods from the data control onto you jspx page, rebuild and test it on embedded OC4J Server.
- Deploy the ear or war file on App Server.
Hope this helps.
Regards,
Phil
