Re: Prevent request filter invocation when struts action tag is invoked

This does NOT work. When an action is invoked using "s:action" in JSP, even
if dispatcher is set as below, the request filter is being invoked.
Is there any work-around?

Thanks.

Re: Prevent request filter invocation when struts action tag is invoked

Posted by Pancham <pa...@gmail.com>.
Here is my request filter code:
public class MyFilter implements Filter {
    private FilterConfig filterConfig = null;
 
    public void init(FilterConfig filterConfig)
            throws ServletException {
        this.filterConfig = filterConfig;
    }

    public void destroy() {
        this.filterConfig = null;
    }

    public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain)
            throws IOException, ServletException {
        if (filterConfig == null)
            return;
        // MY CODE HERE
    }


and here is the mapping in web.xml:
<filter-mapping>
        <filter-name>MyFilter</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
    </filter-mapping>

While processing an request, if I include an action using struts action tag
("s:action"), this filter is invoked again during the same request. So, if I
have 2 "s:action" tags in my JSP, the filter is being called 3 times - once
for request and two times for "s:action".

Any ideas on how this could be addressed?

What REQUEST FILTER is this you are talking about?
