Probelm statement::
We have a webservice which uses the Appian API to make a call to the process model using the Appian API like below:

NamedTypedValue namedTypeValue = new NamedTypedValue(JaxbConverter.toTypedValue(po, bulkAddParameterTypeId, ts),"BulkAddProcessObject");
                              ProcessVariableInstance myBulkUpload = new ProcessVariableInstance(namedTypeValue);
                              ProcessStartConfig con = new ProcessStartConfig();
                              con.setProcessParameters(new ProcessVariable[]{myBulkUpload});
                              processID          =          pds.initiateProcess(pmId, con);

Data is not gettig passed from webservice to the process model.

Findings:
------------
when the below code is invoked - Typed conversion takes place
JaxbConverter.toTypedValue(po, bulkAddParameterTypeId, ts)
po= process object with values
bulkAddParameterTypeId=processobjectid
ts = tyep service
Result of above execution:
NamedTypedValue[name=BulkAddProcessObject,it=980,v={<null>,<null>,,<null>}]
The data is...

Any help? Thanks in advance!!!!!

The problem is that your NamedTypedValue is receiving a name different from your process variable (parameter). Your process parameter (pv) is called "BulkaddProcessObject_PV", however you the object you are creating (NamedTypedValue) is has the name "BulkAddProcessObject"; this will result in the following error in the Appian logs:

WARN .a.p.PROCESS.i "Ignoring these unrecognized process parameters: ,`BulkAddProcessObject"

which makes sense because your process model DOES NOT have a process variable with this name; the right name is BulkaddProcessObject_PV

Here's a screenshot explaining what I just described forum.appian.com/.../51579

Try adding this line right after you create the NamedTypedValue:

namedTypeValue.setName("BulkaddProcessObject_PV");

Which at the end will look like this:

NamedTypedValue namedTypeValue = new NamedTypedValue(JaxbConverter.toTypedValue(po, bulkAddParameterTypeId, ts),"BulkAddProcessObject");
namedTypeValue.setName("BulkaddProcessObject_PV");
ProcessVariableInstance myBulkUpload = new ProcessVariableInstance(namedTypeValue);
.....

Actually you just need to chane this line:

NamedTypedValue namedTypeValue = new NamedTypedValue(JaxbConverter.toTypedValue(po, bulkAddParameterTypeId, ts),"BulkaddProcessObject_PV");

to

NamedTypedValue namedTypeValue = new NamedTypedValue(JaxbConverter.toTypedValue(po, bulkAddParameterTypeId, ts),"BulkAddProcessObject");

I meant:

Change this line from:

NamedTypedValue namedTypeValue = new NamedTypedValue(JaxbConverter.toTypedValue(po, bulkAddParameterTypeId, ts),"BulkaddProcessObject");

to

NamedTypedValue namedTypeValue = new NamedTypedValue(JaxbConverter.toTypedValue(po, bulkAddParameterTypeId, ts),"BulkaddProcessObject_PV");

This is an example that I just created to test this; I hope this helps:

Student studentPOJO = new Student();
studentPOJO.setFirstName("Eduardo");
studentPOJO.setLastName("Fuentes");

String namespace = "xxxxxxxxxx:8002/.../";
String typeName = "Student";
TypedValue typedValue = JaxbConverter.toTypedValue(studentPOJO, ts.getTypeByQualifiedName(new QName(namespace,typeName)).getId(), ts);
NamedTypedValue namedTypeValue = new NamedTypedValue(typedValue,"myStudent");
ProcessVariableInstance myStudent = new ProcessVariableInstance(namedTypeValue);

ProcessStartConfig config = new ProcessStartConfig();
config.setProcessParameters(new ProcessVariable[]{myStudent});
pds.initiateProcess(pmID, config);
