How does Tomcat locate webapps directory? Where is this location set? Is it a relative directory?

It can be changed in the $CATALINA_BASE/conf/server.xml in the <Host />. See the Tomcat documentation, specifically the section in regards to the Host container:

Tomcat 6 Configuration

Tomcat 7 Configuration

The default is webapps relative to the $CATALINA_BASE. An absolute pathname can be used.

Hope that helps.

Find server.xml at $CATALINA_BASE/conf/server.xml

Find appBase attribute in <Host> element

by default it will be something like :
<Host name="localhost" appBase="webapps ...>

Change appBase to your required path. There are different way people put it, but I use

/c:/myfolder/newwebapps

Remember, no slash at the end, but at start. Also note it’s direction as well.

Change appBase in server.xml

If you want to keep both previous webapps and a new one, you can use another Host instance with another port defined in tomcat.

I’m using Tomcat through XAMPP which might have been the cause of this problem. When I changed appBase="C:/Java Project/", for example, I kept getting "This localhost page can't be found" in the browser.

I had to add a folder called ROOT inside the Java Project folder and then it worked. Any files you’re working on have to be inside this ROOT folder but you need to leave appBase="C:/Java Project/" as changing it to appBase="C:/Java Project/ROOT" will cause "This localhost page can't be found" to be displayed again.

Maybe needing the ROOT folder is obvious to more experienced Java developers but it wasn’t for me so hopefully this helps anyone else encountering the same problem.
