Rest Task Error

biswajit.sarkar Feb 27, 2015 5:18 AM

I am using Jboss BPMS 6.0.3.GA.

I am trying to create a process where I added a Rest Task to call Jboss BPMS own REST Api.

here is my rest uri ...

http://localhost:8080/business-central/rest/history/process/project1.RestTask_Process1

If I try this uri from firefox rest client with "Basic Authentication", I'm getting response (Status 200).

But whenever I try this same uri from Rest Task, I am getting Unauthorized Error(Status 401)

here is my REST Task config....

Is it really possible to invoke JBoss BPMS own Rest Api from a Rest Task?

or is it a bug of JBoss BPMS like this https://bugzilla.redhat.com/show_bug.cgi?id=1086639

anyone please confirm this . I am using Jboss BPMS 6.0.3.GA.

The response code 401 is saying that you are not authenticated to the "business-central" to do this. When you are calling the same URL through a browser, probably your are already authenticated, maybe because you have logged in on business-central in the same Browser.

The REST Work Item Handler has some parameters that you configure in your task, like URL, method, parameters, etc. Two of those parameters are Username and Password, that is used for basic authentication, fill it if the business-central credentials, and should work.

I am still getting status 401.

2015-02-28 16:08:26,889 WARN [org.jbpm.process.workitem.rest.RESTWorkItemHandler] (default task-39) Unsuccessful response from REST server (status 401, endpoint http://localhost:8080/jbpm-console/rest/history/process/Project1.Rest_Process, response <html><head><title>Error</title></head><body>Validation fails.</body></html>

I just created a simple process with a REST Service Task and from that REST Service task I try to invoke JBPM's own Rest API.

following is my process file
