xxx.jar – a library of useful classes packaged in a single archive file.

using libraries in your project is dead-easy.

  1. create classes, e.g. a collection of custom tag handlers
  2. zip them up using jar cf mytags.jar *
    or jar cf mytags.jar list-of-files.class
  3. copy mytags.jar into lib/ dir of another project (see More)
  4. use them

Start tomcat

C:\Tomcat55\bin\tomcat5w.exe or C:\Tomcat55\bin\tomcat5.exe

check if it is running:  http://localhost:8085

Note that I set it up on port 8085 because JBoss has already taken port 8080, pluss a dozen of other ports. (Check in the notes which ports are taken – 8083…).

 Drop .war or the unpacked project folder to C:\Tomcat55\webapps

check if URL works – that will be one of the welcome-files in welcome-file-list in web.xml

First, navigate to the progectname dir

jar cvf projectame.war *

jar cf web-app.war *
(What’s the difference between cvf and cf?)

jar cf ear_app.ear web-app.war META-INF
(to deploy on JBoss)

* means “all files in this dir”
