Issue while run the openssp project

[keerthi-cpu]

Hi,

Good day to you!. I have successfully imported the openssp project into my eclipse workspace and deployed the core and dataservices war into tomcat server.

I have few doubts to run. First one, I have seen the two wars with two different port in pom.xml. Can we need to run the war one by one seperately with corresponing port(core - 8080 and dataservices-9090)??.

Then I have tried to run both (core and dataservice) on 8080 , but i got a below error.
