A new JSP project was created ,after the start of the tomcat, the browser only displays the source code.
Initially, the jsp file and associated java classes were built and tested fine on a test Tomcat server. Now, they've been transitioned to another server of what I believe is the same setup (except it's linux now instead of windows). But when the jsp page is accessed the source code is displayed instead of the jsp actually executing. I've googled for a while but received no success.
