Struts2 - Difference between struts.xml and struts-plugin.xml?

Question

I have confusion about these files in struts2. Normally struts.xml file the core which has configuration in struts1. So I also thought of using struts.xml file.

But in my project already they put struts2-config-browser-plugin.jar, it has struts-plugin.xml. Just searched in Google and found that struts-plugin.xml is enough to run struts application.

Now I'm adding the struts.xml file, the application is not working.

1. Can I use both XML file in application?

2. If I remove the struts2-config-browser-plugin.jar , what are the changes need to add in struts.xml file ?

Answer 1

There are three configuration files which are by default loaded by the framework (if they exist):

• struts-default.xml - included in struts2-core.jar, contains all basic configuration of the framework
• struts-plugin.xml - if plugin want to override some defaults or define its own settings (results, actions, etc)
• struts.xml - contains user defined configuration, mostly actions, results and custom stacks of interceptors

You should just use struts.xml and put all the configurations there.
