FreeMarker automatically scans all JAR files in your WEB-INF/lib directory. If it finds .tld files inside a JAR's META-INF directory, like your META-INF/mytaglib.tld, it will peek inside it in order to find the<uri>
tag. If it finds one, it will make the taglib available via this URI, e.g a taglib defined likejava
<taglib> <shortname>my custom taglib</shortname> <uri>http://example.org/mytaglib</uri> <!-- ... --></taglib>
can be used in FreeMarker viaide
<#assign my=JspTaglibs["http://example.org/mytaglib"] />
