How can invoke eclipse bpel process from java Applications

I deploy a simple BPEL process which implemented Add or subtract on Apache
ODE .The path of WSDL which described BPEL process is
"http://localhost:8080/ode/processes/CalcServicePort?wsdl" . 
I test this BPEL process through web services Explorer which is myeclipse
plugin, this test is successful.
But I want to invoke this BPEL process from java Applications .So I try to
invoke this web service through
org.codehaus.xfire.client.Client.Invoke(),but this test is failure,i meet an
error which is "selectionFailure".
How can invoke this web service on java Applications as  general web
services .
thanks!

RE: How can invoke eclipse bpel process from java Applications

Posted by LeeMike <me...@163.com>.

Please show specific call statement. 
I invoke bpel process through blowing statement:
call.setTargetEndpointAddress(new URL(endpoints));
call.setOperationStyle("wrapped");
call.setOperationName(new QName("http://www.icrm.org/test/","process"));
call.setSOAPActionURI("http://www.icrm.org/test/process");
call.addParameter("type",org.apache.axis.Constants.XSD_STRING,
ParameterMode.IN);
call.addParameter("left",org.apache.axis.Constants.XSD_INT,ParameterMode.IN);
call.addParameter("right",org.apache.axis.Constants.XSD_INT,ParameterMode.IN);
call.setReturnType(org.apache.axis.Constants.XSD_INT);
Integer res=(Integer)call.invoke(new Object[]{"add",new Integer(3),new
Integer(4)});

RE: How can invoke eclipse bpel process from java Applications

Posted by Dhanush Gopinath <dh...@altair.com>.

You probably can write a SOAP Client in Java which can send a SOAP
request to the WS endpoint opened up by your BPEL process. Have a look
at the javax.xml.ws package.

How ever the error you mentioned below is probably due the wrong
initialization of variables. selectionFailure typically comes when ODE
is not able to select the exact xml element in an assign. Please look in
the log and see which element is not properly initialized.

Subject: How can invoke eclipse bpel process from java Applications




I deploy a simple BPEL process which implemented Add or subtract on
Apache
ODE .The path of WSDL which described BPEL process is
"http://localhost:8080/ode/processes/CalcServicePort?wsdl" . 
I test this BPEL process through web services Explorer which is
myeclipse
plugin, this test is successful.
But I want to invoke this BPEL process from java Applications .So I try
to
invoke this web service through
org.codehaus.xfire.client.Client.Invoke(),but this test is failure,i
meet an
error which is "selectionFailure".
How can invoke this web service on java Applications as  general web
services .
thanks!
