Chapter 14 Creating Custom JSP Tag Libraries

The format of tag descriptions will be described in later sections. For now,

just note that the 

tag

 element defines the main name of the tag (really tag

suffix, as will be seen shortly) and identifies the class that handles the tag.

Since the tag handler class is in the 

coreservlets.tags

 package, the fully

qualified class name of 

coreservlets.tags.ExampleTag

 is used. Note

that this is a class name, not a URL or relative path name. The class can

be installed anywhere on the server that beans or other supporting classes

can be put. With Tomcat 3.1, the standard base location is

install_dir/webapps/ROOT/WEB INF/classes

, so

 ExampleTag

 would be in

install_dir/webapps/ROOT/WEB INF/classes/coreservlets/tags

. Although

it is always a good idea to put your servlet classes in packages, a surprising

feature of Tomcat 3.1 is that tag handlers are required to be in packages.
