Try creating an action in struts which would have a result entry like :

<action name="start">
<result>/login.jsp</result>
</action>

Then try to direct your website to this location : http://localhost:8080/start

That should work if you are in Tomcat (change the port accordingly)

To make it the default page, make an entry of the /start in the <welcome-file-list> in web.xml

hope that helps!!!

i have stored the struts.xml in ApplicationResources.properties file......

You've placed your xml file in a properties file?? The struts.xml is supposed to go into the WEB-INF/classes directory. So you should put it in the root of your source folder in your eclipse project (the place where any classes with no package goes). After that you need to show us some code, what does your struts.xml look like, your Action class' code, what URL are you entering in the browser??

I am just tying to execute an example from the tutorial available in this link..my code is the same as

http://java.dzone.com/articles/struts2-tutorial-part-27

i have placed my files in eclipse as mentioned in the tutorial.....
still i have getting error.....i have placed the same struts.xml file under WEB-INF/classes folder..........

Turn devMode on, set the log level to DEBUG, and check the startup logs; we'll go from there. Also post the config and deployed directory tree.

You are seeing this page because development mode is enabled. Development mode, or devMode, enables extra debugging behaviors and reports to assist developers. To disable this mode, set: 

  struts.devMode=false

in your WEB-INF/classes/struts.properties file. 
   

I am using Struts 2.1.8.1.....

and my directory for strut.xml is
C:\Software\Tomcat 6.0\webapps\testapp\WEB-INF\classes\struts.xml and rest all the files i have made are in the same path as mentioned in the tutorial....i have put the jsp files Login.jsp and Welcome.jsp in C:\Software\Tomcat 6.0\webapps\testapp directory.....i even made the same jsp and deployed it in eclipse under

C:\Software\workspace\StrutsHelloWorld\WebContent folder......

is there anything else that i am missing???

You'll need to satisfy the missing dependencies before proceeding.

Maggie,

Although the IDE puts a copy of struts.xml in your WEB-INF/classes folder when it builds your project. You will need to have a copy in your /src folder. Mine is in the root of my Java Resources/src folder.

Also, my IDE blows up when in "dev mode" - I don't recommend it.

Good luck,
Marcella

[David Newton]

The issue is with the missing dependencies, as the stack trace states.

If your IDE "blows up" with devMode on then something is wrong with your IDE setup; I run in devMode during development under several IDEs without issue.
