Question

I am using IntelliJ Ideea 13.1.4 and I encountered this error - after I Run / Debug my project, after "Artifact portal-webapp:war exploded: Artifact is deployed successfully"

I get this error but it has been working util now...

Do you Have any idea what should it be?

Answer 1

It appears Idea is trying to wait for your page to return 200 response and then open the external web browser. If this does not happen (e.g. your application returns a redirect due to authentication filters), Idea is just spamming your application with requests and then complains about not being able to open the web page.
