How to invoke BPEL process via HTTP POST (or GET)

Hi,
I'd like to know how to invoke BPEL process via HTTP POST (or GET), is there anyway simple to do it?
Thank you

Look at my blog http://orasoa.blogspot.com search for plsql
or use SoapUI.org

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.

How to invoke BPEL process from database?

Who can get an advice: what technology is better to use for invoking BPEL process, that is deployed to remote server, from database? What LIBs should I load into this database?
History: after successful trying Oracle RMI-example whith JDeveloper, I repeated the same had loaded my .jar and all listed in project Oracle .jar's into the database and received error "..class not resolved..".
Thank you.

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

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.

BPEL process with http-POST service doesn't work

Hi OraclePM community,
i tried to test a http-POST service. The message i wanted to send is very simple:
<?xml version="1.0" encoding="UTF-8"?>
<GetFeature service="WFS">
<Query typeName="states"/>
</GetFeature>
In the POST-service wsdl:types/xsd:schema i created this new element to ingest the request-xml:
<xsd:element name="GetFeature">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Query"/>
</xsd:sequence>
<xsd:attribute name="service" use="required" type="xsd:string"/>
</xsd:complexType>
</xsd:element>
<xsd:element name="Query">
<xsd:complexType>
<xsd:attribute name="typeName" use="required" type="xsd:string"/>
</xsd:complexType>
</xsd:element>
I made the same in the bpel-service wsdl for input-variable definition. When i deployed the bpel process and went to the automatically generated client then i had only two input-boxes. One box to type in the 'service' (which is signed as string) and another box to type in the 'Query' (which is signed as anyType). But thats a wrong interpretation of my wsdl. I should type in the 'typeName' which is also a string. Therefore i get an exception at the invoke: "Argument 'GetFeatureIn' is not compatible".
O.K. i tried something different: In the client i din't choose the option 'html-form' but the option 'xml-source' and copied the request-xml in there. The result was another exception earlier (the first assign after the receive). The exception is: "error in evaluate <from>-expression in line "33". The result for the XPath-expression "/client:GetFeature" is empty"
Can anybody help me?
Kind regards
Albrecht

sure you send the right xml?
what I would try is to copy the xml from the receive, paste and extend it, and see if this works . . these errors are mostly because of no namespace defined or such ..
sure your element has the right namespace?
hth clemens
2)
here is the xml for the following schema ..
XML
<ns1:AttributetestProcessRequest xmlns:ns1="http://xmlns.oracle.com/Attributetest">
<ns1:input/>
</ns1:AttributetestProcessRequest>
schema
schema attributeFormDefault="unqualified"
     elementFormDefault="qualified"
     targetNamespace="http://xmlns.oracle.com/Attributetest"
     xmlns="http://www.w3.org/2001/XMLSchema">
     <element name="AttributetestProcessRequest">
          <complexType>
               <sequence>
                    <element name="input" type="string"/>
               </sequence>
<attribute name="service" use="required" type="string"/>
          </complexType>
     </element>
     <element name="AttributetestProcessResponse">
          <complexType>
               <sequence>
                    <element name="result" type="string"/>
               </sequence>
          </complexType>
     </element>
</schema>
it works design and runtime in 10.1.3.1

How to Invoke bpel process which is deployed in weblogic using java code

Hi
I want to invoke a BPEL Process which is deployed in Weblogic server using Java code. Please provide me the code snnipet which will be used to connect and then invoke a BPEL Process.

The simple way would be creating a java client to consume the SOAP webservice interface exposed by the bpel process.
If you have Oracle Service Registry you can also use UDDI to discover the endpoint at runtime.
But you can also use direct binding to do that.
If you search on internet you will find many blog entries about this as well as many related posts here on OTN.
I can't suggest a specific one, but looking on Google this one seems quite ok: Managing Oracle SOA Environment [10g/11g]: Invoking SOA11g Composite Using Direct Binding Invocation API

Invoking BPEL process on startup

Hi there,
Does anyone have suggestions as to how i can run a BPEL process automatically when BPEL PM starts up? I would prefer not to use external tools. I tried using the OC4J startup classes invoking it via java, but the BPEL engine has not started the processes yet.
I'm using 10.1.3.3.0
Thanks
Edited by: user5535771 on Nov 24, 2008 2:12 PM

Hi,
Your current usecase:
Step 1.java app polls db-->jms topic1 written to that jmsbroker/consumers consume
Step 2.jms broker receives msgs from topic1-->invokes http post
Question: It is unclear whether you will have other consumers to this jms msg or not and hence two options.
Here are the ways to use BPEL with this:
Option 1:
If you dont want the current JMS broker but want a JMS provider so other consumers can consume the msg
1.java app polls db, gets xml msg, puts msgs into Oracle JMS.
2. Within a bpel process, the jms adapter listens for arrival of msgs on a q/topic and calls http post (inline java exec or http binding)
For bpel process doing http post refer: for inline java call<bpelhome>/samples/references/javaexec) and "702Bindings" for http binding.
Application specific JMS headers will be set by the enqueuing client (your java app in this case). In general getting and setting of JMS headers is possible within bpel.
Option 2:
If you dont want the current JMS broker and dont care about other msg consumers either
1. java app polls db, gets xml msg, invokes bpel process thro bpel java api
Ref: 102.InvokingProcesses
2. Within the bpel process, the steps are : a) receive msg frm client b) do http post
Again, if you directly have access to the underlying tables, refer to Option 1 in the previous post.
Wrt "Also, is there a way that I can make my existing java application to be initialized by a bpel process",
yes within bpel you can write inline java or do wsif binding to invoke java code.
You can contact me at [email protected]

Hi, thanks for your reply i knew the FileUplaod was the way forward.
I read topics advising to use the FileUpload and tried the following but it did not seem to work ( i get an HTTP Internal Server error when i try that):
try
DiskFileUpload upload = new DiskFileUpload();
boolean isMultipart = FileUpload.isMultipartContent(request);
if( isMultipart )
List items = upload.parseRequest( request );
Iterator iter = items.iterator();
while( iter.hasNext() )
FileItem fileItem = ( FileItem ) iter.next();
File uploadedFile = new File("myreceivedfile.zip");
fileItem.write( uploadedFile );
}catch (Exception e)
System.out.println("RECEIVER: " + e.getMessage());
Also DiskFileUpload,isMultipartContent and parseRequest have a line going through the middle (horizontal middle).

Call Bpel process through HTTP get or post method

I need to call BPEL process from Mobile.
In mobile we are using HTTP get or post methods. so can anybody tell me how to invoke BPEL(how to pass input to BPEL) by using HTTP get or post method.
Vivek garg
Edited by: 809104 on Dec 24, 2010 2:36 AM

I got the soluntion
we just need to change the binding in WSDL file from Soap to HTTP.
First of all add three namespaces in wsdl file
xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/"
xmlns:http="http://schemas.xmlsoap.org/wsdl/http/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
Then change the Request msg from element type to string type like below
<message name="UserLoggOffRequestMessage">
<part name="UserId" type="xsd:string"/> (add this one))
(remove this one)
</message>
Then change the binding
<binding name="UserLoggOffBinding" type="client:UserLoggOff">
<http:binding verb="GET"/>
<operation name="process">
<http:operation location="/process"/>
<http:urlEncoded/>
<output>
<mime:mimeString part="Body"/>
</output>
</operation>
</binding>
Then do some changes in service tag . we need to do the changes in location only.
we need to remove orabpel from location and add httpbinding
http://infva04718.vshodc.lntinfotech.com:8888/*orabpel*/MobileApplication/UserLoggOff/1.0
http://infva04718.vshodc.lntinfotech.com:8888/*httpbinding*/MobileApplication/UserLoggOff/1.0
do like following
<service name="UserLoggOff">
<port name="UserLoggOffPort" binding="client:UserLoggOffBinding">
<http:address location="http://infva04718.vshodc.lntinfotech.com:8888/httpbinding/MobileApplication/UserLoggOff/1.0"/>
</port>
</service>
Then deploy the process then u can invoke this
http://infva04718.vshodc.lntinfotech.com:8888/httpbinding/MobileApplication/UserLoggOff/process?UserId=a1
here process is name of process u want to invoke

Invoking BPEL process: how to decide it's two way or one way operation

Hi,
I'm using IDeliveryService to invoke BPEL process. Is there API available that allows me to check whether the operation is two way so I call IDeliveryService.request() or is one way so I call IDeliveryService.post()?
Thanks,
Qian

hi,
By observing WSDL of the BPEL process you can identify that whether its
two way operation or one way. If operation has two variables - both input & output
then its way operation and if the opration has only one variable - input variable then
its one way operation.
OR are you asking how to check it at runtime without looking at the WSDL...?
