How to exclude/redirect certain url pattern in web.xml or Guice servlet module?

I need to serve my main application with the url pattern "/*" so this pattern is matched to a Servlet. The problem I am having is now all the css files and images located at "/css/all.css",开发者_运维知识库 "/images/" etc are going through this Servlet which is undesirable. I want these files to be directly accessed. What is the better way to handle this situation?

Note: I am using Guice's Servlet Module to configure the patterns.

Thanks!

We need to know specifically which requests should be routed to your servlet, so that we know how to code the rules. I can't tell whether a) all requests except CSS and images should be sent to your servlet, or b) your servlet should only handle requests to a specific set of folders/directories. You will probably want to do one of two things:

Exclude specific folders:

^/(?!css|images).*

Or include specific folders:

^/myservlet/.*

You should change those * symbols to + if, as you indicated in your earlier question, you want to require at least one character after the / in the pattern.

This should work for you:

Make all your image/css etc resources go through the default servlet. And make a mapping like this:

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.xml</url-pattern>
    <url-pattern>*.html</url-pattern>
    <url-pattern>*.png</url-pattern>
    <url-pattern>*.jpg</url-pattern>
    <url-pattern>*.gif</url-pattern>
    <url-pattern>*.js</url-pattern>
    <url-pattern>*.css</url-pattern>
</servlet-mapping>
