mule studio multiple projects running connection refused - mule

Question

I'm doing some development in Mule studio. I have 2 REST services in 2 different projects and would like to run both of them on my environment. When I run them independently they run ok.
Service A on port 8081 is calling service B (Account) on port 8083.
I Run As a Mule application for service A on port 8081 and then do the same for service B on port 8083.
When the flow goes to callout to service B I get the below error.
Thank you for your help.

Answer 1

Currently it is not possible to run multiple application at the same time as you can see from this jira.
To overcome this problem you have 2 options:
Create a separate integration test project that depends on the two mule application and runs all the flows toghether either within a Functional testcase
Use the org.mule.MuleServer main class passing to it all the config files you want to load
