Error 404 upon Start up of Struts2 in tomcat

Question

I was making this hello world application using Struts2 and I've encountered an

HTTP Status 404 - /HelloStruts2/

Here is my web.xml

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

Give error log. i had same problem in past and i resolved by changing jar files. Please check error log. i am sure problem in jar files. — MRX, Dec 05 '12 at 10:13
What does it say in Tomcat's catalina.out? Most importantly, what does it say after you start the container ( or install the webapp ), and what does it say after you make the request? ALSO, you should probably document the whole request path that isn't working in your question: URL --> struts mapping --> Action class --> result template, etc. — chad, Dec 05 '12 at 15:47

I Have fixed it, It turns out that I just need the commons-lang jar to may lib directory.

Try the following code segment in web.xml(in the struts filter user the pattern *.action)

<filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>*.action</url-pattern>
</filter-mapping>

There was nothing wrong with the posters /* mapping. In fact, it's suggested on the struts 2 documentation site . . . – chad Dec 05 '12 at 15:43

I had same problem, and i struggled to solve it for many hours, even i placed proper jars mentioned above.

I have faced this problem because there are too many jars files under the folder common->lib of the apache tomcat causing the issue.

So

1) Keep jars and there dependency neatly 2) Check jars under the lib folder of your web-inf for the dependency. 3) check jars containing same classes but having different version.

I found solution when i uninstalled tomcat and re-installed it.
