Sometimes, running my App via WebShell or the mobile does not render - the App screen is empty or seems to be loading for too long. The reason could be the failed deployment.
Run your App from IDE
Pay attention to the errors in the IDE console
Go to the tomcat deployment folder (c:\hp\hpanywhere\tomcat\webapps)
Make sure your App deployment folder exists, for example c:\hp\hpanywhere\tomcat\webapps\TroubleShooter-web
In case the folder does not exist or there are few files there, redeploy the App - Delete the App deployment folder - Delete the App's ZIP and WAR files under tomcat deployment folder - Perform Clean operation from IDE
