I'm a rookie with struts and I have some problems
with html tags.
I use the java version 1.4.0-beta3, struts 1.0.1 and
tomcat 4.0.1.
When I execute the example of struts
struts-exercise-taglib in this parts
HTML Tags
* <html:link>
* <html:multibox>
* <html:select>
* Scalar Setters
I receive the error of the final of the page.
I have configured correctly JAVA_HOME,
CATALINA_HOME and the PATH.
What can I do?
The others parts of struts-exercise-taglib runs
correctly.
I receive the following error:
Apache Tomcat/4.0.1 - HTTP Status 500 - Internal
Server Error
type Exception report
message Internal Server Error
description The server encountered an internal error
(Internal Server Error) that prevented it from
fulfilling this request.
