Custom Tags

[Gerard Garrigan <ge...@precisionsoftware.com>]

Hello,

I'm trying to write a custom tag for JSTL. I have written the Java
class, the tld and the jsp page but when I run the application I get the
following error in Tomcat:

org.apache.jasper.JasperException: Unable to initialize
TldLocationsCache: null
	
org.apache.jasper.compiler.TldLocationsCache.init(TldLocationsCache.java

	javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

Would anyone be able to help me out with where I'm gone wrong?

Thanks very much,

Ger
