can't change or add action in struts2

i am having a problem with struts i've been working with struts with more than 4 month now
the problem is when i add a new action i get this:

enter image description here

the previous actions work fine but when i modify the name of the action in struts.xml i get the error i mention above.
so for example i have the following code in struts.xml

<action name="test1" class="com.onda.beans.AfficheVolList">
<result name="success">table_vols_test_css.jsp</result>
<result name="fail">admin.jsp</result>

when i enter http://localhost:8080/Myproject/test1 it works fine
but after i change the name of the action

<action name="test2" class="com.onda.beans.AfficheVolList">
<result name="success">table_vols_test_css.jsp</result>
<result name="fail">admin.jsp</result>

and i try to enter localhost:8080/Myproject/test2
i got the error in the previous image it doesn't even take me to admin.jsp

i tried to clean the server and clean work directory but nothing work i even changed the server it works for the first time but after i change the name of the action it doesn't work
here is the log

thank you for taking time to answer my question i really appreciate it

Answer Source

This is probably a problem in your Apache Tomcat server configuration.

Your struts.xml looks perfectly fine and there is no reason changing the name would break the action.

Here's a few things you could consider doing and that might solve your problem:

  • Restart Tomcat

Depending on your linux distro and Tomcat version, this might differ.

sudo service tomcat7 restart
  • Restart your computer
  • Delete and reinstall Tomcat

I hope this helps.
