Invoke Bpel Processes via API or Web Service Proxy Clients

Hi all,
I was wondering if any of the felow community members have found information regarding best practices in invoking bpel processes from a user interface other than ADF Faces?
Currently I'm using Web Service Proxy Clients to invoke my bpel processes, but I was wondering if it would be better to use the BPEL API?
Considerations I have regarding these 2 different approaches are mostly tight integration when using the BPEL API, because this means I have to port the BPEL (Oracle Code) inside my UI-application which isn't the case when using Web Service Proxy Clients.
What is the best way to instantiate bpel processes from a user interface, is that by using web service proxy clients or by using the bpel i
nvocation API?
Kind regards,
Nathalie

Hi Marc,
These were my considerations as well, but I was looking for some kind of benchmarking regarding these 2 approaches. What's best practices when hooking up bpel inside UI Applications regarding performance, future-proofness (SOA Grid, SOA Composites, ...) etc.
I think I need to discuss this with the product team to make sure I'm taking the wright decisions.
Kind regards,
Nathalie

Authorization Error While Invoking BPEL Process Via RMI

Hi All,
I have been trying to invoke BPEL Process via RMI client.
I use the following piece of code for BPEL Process Invocation...
public class RMIClient {
public RMIClient() {
public static void main(String[] args){
Hashtable jndi = new Hashtable ();
jndi.put (Context.PROVIDER_URL, "opmn:ormi://host:6010:oc4j_soa/orabpel");
jndi.put (Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
jndi.put (Context.SECURITY_PRINCIPAL,"oc4jadmin"); // username of Bpel Manager
jndi.put (Context.SECURITY_CREDENTIALS,"welcome1"); //password of BPEL Manager
Locator locator=null;
try {
locator = new Locator("default",jndi);
} catch (ServerException e) {
e.printStackTrace();
IDeliveryService deliveryService =
(IDeliveryService)locator.lookupService
(IDeliveryService.SERVICE_NAME );
// construct the normalized message and send to oracle bpel process
NormalizedMessage nm = new NormalizedMessage( );
String xml = "<ns1:MyFirstBPELProjectProcessRequest xmlns:ns1=\"http://xmlns.oracle.com/MyFirstBPELProject\">\n" +
" <ns1:input></ns1:input>\n" +
" </ns1:MyFirstBPELProjectProcessRequest>";
nm.addPart("payload", xml );
NormalizedMessage res=null;
try {
res = deliveryService.request("MyFirstBPELProject", "process", nm);
} catch (ServerException e) {
e.printStackTrace();
} catch (RemoteException e) {
e.printStackTrace();
Map payload = res.getPayload();
When I try to connect to my locally deployed BPEL process Manager and Invoke the same process (MyFirstBPELProjectProcess ) it works fine and creates an Instance on BPEL Process Manager Console.
When I tried Invoking the same BPEL process (MyFirstBPELProjectProcess ) deployed on a Remote machine ,it doesnt create an Instance.
I believe my connections settings are all correct ,since it doesnt give me an connection issue on my standalone client.
I tried looking at the following file default_group~oc4j_soa~default_group~1.log available opmn folder under SOA Suite OAS and there
are no errors.
Could some body point the log files that I need to look at.
I am sort of clueless...
Regards
Harish

CAn you post the error. HAve you made sure that the remote machine has connection on the port 6010. You can test this with the folloing command from the remote machine
telnet host 6010
obviously replace host with the fully qualified host name of the SOA machine.
cheers

Web Service Proxy client to invoke a Web service on SSL (Jdev 10.1.3.1)

Hi,
I have to develope a Web Service proxy client to invoke a web service on SSL. First I'm testing with OC4J 10.1.3.1 and JDEV 10.1.3.1 and did this:
1) Developed a basic PL/SQL Web Service with JDEV and publish on my standalone OC4J.
2) Made a test with a browser, it worked OK
3) Generated a proxy client from JDev 10.1.3.1 to invoke web service, it worked OK
--- Now make it work on SSL----
4) Then, added SSL configuration to oc4j , generated a certificate with keytool (updated server.xml, secure-web-site.xml), and shutting down and starting the OC4j instance.
5) Import the certificate to JAVA_HOME/jre/lib/security/cacerts
6) Test web service from browser on https and worked OK.
7) When tried to modified proxy client (generated in step 3) to make it work on SSL, I realized that just changing the END_POINT to the new url (https) it worked!
Questions----
1.- By default the proxy client generated from JDEV 10.1.3.1 knows how to deal with SSL conections?
2.- If I dont have previously the server certificate to import it into JAVA keystore (cacerts) how could I ,from proxy client code, capture it and import it before the validation occurs... because if the certificate is not in keystore , the program fails.
Thanks in advance
J.

Hi,
Could you please provide me with the steps necessary to create a web service proxy client through JDeveloper or any other mechanism when 2 way SSL (requiring client authentication) is enabled.
Thanks a lot in advance

Distributing Oracle Web Services Proxy client?

Hi,
We built a web services client using Web Services Proxy tool in JDeveloper. We want to distribute it as a stand-alone application to our clients.
1. How can we determine the minimal set of JAR libraries required for the application to run?
2. Are there any licensing issues?
Thanks!
Simeon

If you are not using any ADF libraries there is no licensing concerns.

Create Lead with Oracle BPEL process using Siebel CRMOD web service

I'm trying to create a lead in the siebel OD (hosted) with a oracle BPEL process and using the siebel web service (2.0). In my bpel process I've been able to
1. Login to OD and get a session id
2. create the partner link using Siebel OD (version 2.0) wsdl for Lead
3. Assign the session id to the partner link
4. Assign the inputs (lastname, firstname, leadowner, viewMode=Personal, lovLanguageMode=LDC) to lead
5. Call the leadInsert operation on the partner link
However, when I deploy and execute the bpel process it breaks after calling the leadInsert with the following error message:

Hi,
We are also using BPEL to send data out to SIEBEL CRMOD.
I've created a proxy that deals with authentication and session management.
All you have to do is to deploy the proxy as a war file and refrence it as the end-point of your partner link.
Code is here:

Problem invoking BPEL process via SOAP

Hi,
I have a BPEL process which runs perfectly when invoked from the BPEL console. Now I try to invoke the BPEL process from another (Java) program and get some strange error message in the client. After enabling debug logging I can see a NullPointerException in the BPEL server log (it's Oracle BPEL server 2.1.2 build 1226).

This sounds very similar to how my BPEL process behaves. I'm unable to post XML input into the "XML Source" region of the initiate screen unless the input is properly wrapped in the respective message type element.
Make sure your invoking client code is wrapping the input properly with the message type XML elements.

How to use server-side classes in a web service proxy client ?

Greetings,
I'm using WebLogic 10.3 with Workshop 10.3 on Windows. I generate a Web Service client in Workshop. There are two options in the New->Others->Web Service category: ClientGen Web Service Client and Web Service Client. I've chosen the second one as it's a JAX-WS Web Service and I think that the first one (ClientGen Web Service is to be used with JAX-RPC Web Services. The proxy is generated but, since the Web Service is using POJOs as parameters, a new version of these POJOs is also generated. For example, my Web Service has an operation like: public OrderStatus putOrder (Order), where OrderStatus and Order are application scoped POJOs. The proxy generation process generates a _PortType class which is supposed to be used by the calling client. This class defines an operation public OrderStatus putOrder(Order), but the OrderStatus and Order classes aren't the original ones but the generated ones. The issue is that these generated classes aren't completely equivalent to the original ones, for examples all lists become arrays, the constructors are different, etc. This is extrememly annouying. Is there any option to say to the proxy generation process to keep with the server-side classes ?
many thanks in advance for any help.

The only solution to this problem seems to be using dynamic proxies. But it doesn't work neither as the following code:
Service service = Service.create(new URL("http://localhost:7001/OrderServiceProject/OrderService?WSDL"),
new QName("http://www.simplex_software.fr/demo/services", "OrderService"));
OrderService orderService = service.getPort(new QName("http://www.simplex_software.fr/demo/services", "OrderServicePort"), OrderService.class);
raises the following exception:

Web service proxy client generation fails

Hello,
i want to generate a webservice proxy client of a web service. For the access to the wsdl file of this web service, basic authentication is required. How can i use the proxy generation tool with username and password? The wsa.jar -genProxy doesn't work because i dont know how i can submit username and password. Is it possible to integrate username and password anywhere?? Is there an other way to generate a webservice proxy client? Please help me :(
Thanks a lot from Berlin!

Web service proxy client from Oracle DB

I need to call an external webservice from oracle db... but this web service does not support "SOAP with attachments" and its specification says that we have to develop a J2EE proxy client to access this web service, this still could be done in a stored procedure, loading jdeveloper generated code in java?, I know that with Jdeveloper I can generate a 'web service stub/skeleton' but how make this stub accesible from oracle with PL/SQL? is this possible?
thanks in advance

Web Service Proxy wizard doesn't open up in edit-mode anymore

I've created a web service proxy project for my existing bpel processes and since the bpel processes server has changed, the endpoint has changed as well.
When I update the endpoint in the <webservicename>_Stub.java file from the webservice proxy client everything works fine.
But when I try to go back in edit-mode inside the wizard, the wizard complains about the old endpoint url of the bpel process. If I search in the project after that specific hostname, I can't find any file or folder referring to the old url.
Could somebody explain me why I can't invoke the wizard anymore for a web service proxy client if the endpoint has changed?
Kind Regards,
Nathalie

Hi Nathalie,
Which version of JDeveloper are you using?
With the latest release, 11g Tech Preview 2, I don't think you can re-enter the wizard by double-clicking on the service proxy icon on the application navigator tree.
From the context menu, the only option is to edit handlers, add custom mapping, security or reliability.
I have found that using ant-based tasks is a better way to get predictable and reproducable outputs, even if the learning curve is not easy.
Here is just a snippet to give you a concret sample:
<target name="genproxy">
    <delete dir="./gen_src"/>
    <o :genProxy wsdl="http://${endpoint.host}/pge/webservice?WSDL" output="./gen_src"/>
    <o :genProxy wsdl="http://${endpoint.host}/pge/webservice?WSDL"
                mapheaderstoparameters="true" databinding="false" output="./gen_src"
                packagename="com.selectg"/>
</target>Hope it helps,
-Eric
I add an extra space in the XML, so that the o: prefix is displayed in the XML snippet
