Hi
I am trying hard to get started with tag libraries, but for some reason I
keep getting an empty "HTTP 500 Internal server error" page when I call the
JSP page which uses my tag library - and the error is not explained in
Orion's log files.
I get the error when I try to use my tags - not when I reference the
library. I feel confident that my reference to the taglib in my JSP is
correct, because using a reference to an unexisting taglib results in an
error. But as soon as I call a tag from the library i get the error - i.e.
when writing something like <mytaglib:helloWorld>.
Below is a thorough description of the situation - any comments / thoughts
would be appreciated.

Here is my setup:
============== the server ===============
Orion 1.3.8 running on Windows 2000 Professional
============== the tag ==================
public class HelloWorldTag extends TagSupport {
public int doEndTag() throws JspException {
try {
pageContext.getOut().write("The Tag says hello world!");
}
catch(java.io.IOException e) {
throw new JspTagException("IO Error: " + e.getMessage());
}
return EVAL_PAGE;
}
}
============== web.xml ==================
...
<taglib>
<taglib-uri>jet</taglib-uri>
<taglib-location>/WEB-INF/lib/taglib.jar</taglib-location>
</taglib>
...
============== test.jsp =================
....
<%@ taglib uri = "jet" prefix = "jet" %>
....
<p>
<jet:helloWorld>
</p>
....
============= taglib.tld ================
....
<taglib>
<tlibversion>1.0</tlibversion> <jspversion>1.1</jspversion>
<shortname>jet</shortname>
<uri>http://www.orionserver.com/tutorials/mytags.jar</uri>
<info>My first Tag library</info>
<tag>
<name>helloWorld</name>
<tagclass>dk.rockit.jet.HelloWorldTag</tagclass>
<bodycontent>empty</bodycontent>
<info>A Hello World tag</info>
</tag>
....
============ taglib.jar ================
