Hi all,
I am using Tomcat 4.01; Windows 2000 ; Struts v1.0
I created a tag which displays a message on the screen. I followed the
basic layout of the example that came with struts. by "layout" I mean:
1. I created a tag under the /classes directory. this time I put it right
under the /classes directory so I didn't need to deal with package names.
2. I added the tag in the app.tld (which is right under /web-inf)
3. On my jsp page, I reference the TLD file and gave it a prefix "app" (just
like the example).
<%@ taglib uri="/WEB-INF/app.tld" prefix="app" %>
when I do " <app:hello /> " in my JSP page (Bid.jsp) I get:
Generated servlet error:
C:\Program Files\Apache Tomcat 4.0\work\localhost\blank\bid$jsp.java:143:
Class org.apache.jsp.HelloTag not found.
HelloTag _jspx_th_app_hello_0 = new HelloTag();
^
I am not sure why it's looking for my HelloTag under org.apache.jsp when I
put it on the /classes directory. I have other Java files right under the
/classes directory and Tomcat 4.0.1 was able to find them - although they
were not custom tag file, but that shouldn't matter, right?
thanks in advance,

p.s. below are parts my app.tld and web.xml files and the rest of the error:
======== app.tld ================
<tag>
<name>hello</name>
<tagclass>HelloTag</tagclass>
<bodycontent>empty</bodycontent>
</tag>
======== web.xml ================
<taglib>
<taglib-uri>/WEB-INF/app.tld</taglib-uri>
<taglib-location>/WEB-INF/app.tld</taglib-location>
</taglib>
======== error message ================
