How can I start a process and get response before arriving to wait state

Hello,

I designed a very long and complex WF with up to 30 service tasks at the beginning and then user task.

When I run the WF through Activiti-Explorer the WF run just fine.

But, When I run the WF through Activiti-Rest, I get Internal server error 500.

This phenomenon happened again with WF that start with one service task that last for 3 min and after that there is user task.

I think the problem is that response for "start process" request is not given until WF reach wait state (user task for example) - the connection channel cut after a while without receiving the response.

Am I right?

I yes, How can I avoid it? How can I start a process and get response before arriving to wait state?

This is the request url I use:

http://localhost:1248/activiti-rest/service/runtime/process-instances/

Body:

{
"businessKey": "406401",
"processDefinitionId": "virusFound:29:147645",
"variables":
[
{
"name": "IncidentId",
"value": "406381"
},
{
"name": "IPHostName",
"value": "sdadas"
},
{
"name": "SuspiciousFilePath",
"value": "sadas"
},
{
"name": "mail",
"value": "svccyberapp@mnrlab.local"
}
]
}

Thanks,

Maayan

You should use a message start event rather than starting it in a regular fashion.

With the message start event, it is simply a fire and forget, the process will complete in it's own good time and you will get an immediate response.

So....

1. Change the model to use a message start event (it can be in addition to the regular start event if you want).

2. When calling from REST, use the URL:
POST http://<host>:<port>/service/runtime/process-instances

POST Payload:

{ "message":"newOrderMessage", "businessKey":"myBusinessKey", "tenantId": "tenant_1", "variables": [ { "name":"myVar", "value":"This is a variable", } ] }

Hope this helps,

Greg
