I solved the issue by adding default-action-ref tag, for example,

<default-action-ref name="home" />

after package tag

in struts.xml

<package name="user" namespace="/" extends="struts-default">

<default-action-ref name="upload" />

Right click the project. Go to properties deployment build path and add all .jar files to /WEB-INF/lib.
Then you shouldn't get this error.

struts.xml should be located under directory: src/struts.xml..

And WEB-INF/web.xml you we need to configure the struts based on filter..

Answer 5

I had the same issue and I was facing it because of not mentioning the namespace correctly in struts.xml.

I added the following snippet in the web.xml :

<welcome-file>login.jsp</welcome-file>

and also making the namespace as "/" default... Hope it answers your query..

Answer 6

You have to create a classes/ folder under WEB-INF/ and put in your struts.xml file!
