Nested Tag Tutorial (keyboardmonkey.com)
Folks
I am having problems getting the keyboardmonkey nested tags tutorial
working. I can get only the most basic part working and get the hello
message, I tried making the changes up to milestone 1 with no success and
even after I download and use the milestone one war file that is on the
site I still get the following error:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it
from fulfilling this request.

After downloading the war file all I did was copy the common-xxx jar files
and the struts.jar files to the WEB-INF lib directory and compile the
MonkeyBean correctly in the relevant directory. The class file is obviously
found as this is not the error that I get. I am using Tomcat 4.1.24 and it
is correctly in
C:\jakarta-tomcat-4.1.24\webapps\nested-tutorial\WEB-INF\classes\com\km\stru
ts\tutorial directory.
The problem is eliminated if I remove the nested tag stuff from the
tutorial.jsp i.e. take out
Monkey Name: <nested:text property="monkeyName" /><br>
Monkey Age: <nested:text property="monkeyAge" /><br>
then app does display a blank jsp page. The version of struts that I use is
1.1-b2 beta version. Any ideas/things that I can double check, I would
appreciate it as using the nested tags appears to be exactly what I am
looking for.
If anybody needs any more info please let me know.
Cheers in Advance,
Mark

Re: Nested Tag Tutorial (keyboardmonkey.com)
Posted by Lynn Guy <lg...@yahoo.com>.
I was getting this error also. I have another struts
application working in my environment so I copied the
struts files and checked the versions of dtds in the
.xml files to match that environment. Voila, it
started working. My environment had struts-nested.tld
and the download was using nested-tags.tld. I'm not
experienced enough at this point to explain exactly
what the problem was but seems there was some
inconsistency in the environment.
