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)});
