Local site not reflecting updates in code changes?

Hello, new to CQ, so I may be missing something. Editing a .jsp files code in IDE (intellij), run author and publish, when I view the page in the AEM, the edit is apparent. However when I activate/publish this page the corresponding page on the local version in the browser does not show the update. I have done full refresh on the browser, opened in different browsers, but the edit is not reflected. Is there some default caching at work here, I have heard mention of 'dispatcher' is this what needs clearing. Most other CMS systems I have used just have a reload application, clear cache option.

n.b when I push a page through the Intelli Vault it sends successfully but then shows and error pop-up 'Error while deleting temp contents', is this related?
