Struts2 .action extension causing CSS, JavaScript and Struts Dojo to break

Question

We have been running on Struts 2.1.8 for some time and all Struts actions have been working as expected, i.e. href\'s to the Struts actions are rendered with the action name

Answer 1

Try to use struts action exstension with comma like this
<constant name="struts.action.extension" value=","/>.
From the struts2 properties file:

Used by the DefaultActionMapper You may provide a comma separated list, e.g. struts.action.extension=action,jnlp,do The blank extension allows you to match directory listings as well as pure action names without interfering with static resources, which can be specified as an empty string prior to a comma e.g. struts.action.extension=, or struts.action.extension=x,y,z,, struts.action.extension=action,,
