Error on Stripes

Question

I got this page:

HTTP Status 404 -

type Status report

message

description The requested resource () is not available.

Apache Tomcat/7.0.11

This is what appeared on console:

SEVERE: Exception starting filter StripesFilter

I followed this diligently, what could I have forgot? http://www.stripesframework.org/display/stripes/Quick+Start+Guide

I'm using Tomcat 7.0, Java 1.6.0_24, using Dynamic Web Project under Eclipse, this is my Eclipse version:

Eclipse Java EE IDE for Web Developers.

Version: Helios Service Release 1
Build id: 20100917-0705

If it has a bearing, I'm using Mac OS X

Detailed error message:

Answer 1

Usually issues like this are caused by either an incorrect web.xml file, or by a required JAR file not being on the classpath.

If you check Tomcat's log directory (should be under CATALINA_HOME/logs) you should find some log files named '<hostname>.<date>.log' (for instance, "localhost.2011-03-18.log"). In the current log file you will likely be able to find a stacktrace that will provide a lot more detail about the exact cause of the error.

Answer 2

Copy commons-logging.jar to your /WEB-INF/lib dir

Regarding to your link:

For deploying and running Stripes you will also need to copy the following library files supplied with Stripes into your classpath:

* commons-logging.jar (1.1)
