| For 2023 (and 2024 ...) - we are now fully retired from IT training. We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk. Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active! I am also active in many other area and still look after a lot of web sites - you can find an index ((here)) |

What are WEB-INF and META-INF directories?
If you're looking at a web application on your Tomcat server you'll see all the files that you would expect - things like an index.html (or perhaps an index.jsp), images, and perhaps style sheets, a robots.txt and a favicon.ico. You'll also see a WEB-INF directory, and perhaps a META-INF directory that are unbrowsable. What are they? The META-INF directories related to .jar files ... they contain the manifest (list of contents) of a jar and are created when you write a jar file. Then when you unpack it, the directory appears. Web applications, held in .war files, are just special cases of .jars. You should (in theory) be able to safely delete your META-INF directory and content from an installed web application. The WEB-INF directory contains a heirarcy in which you'll find the necessary configuration information for your web application, and all the class files for your servlets and classes that are called up by your JSPs (Java Server Pages). The WEB-INF directory is a vital component of your web application, which will not run without it!
