Defining a ServletFilter – the SEAM way

SEAM doesn’t only extends JSF and Facelets, but also gives you a possibility to define other resources or components via annotations. To define a simple Servlet Filter you only need to annotate a class with the @Filter-annotation. There is no need to extend the web.xml or other.

One simple Filter would be:

?View Code JAVA
1
2
3
4
5
6
7
8
9
10

@Scope(ScopeType.APPLICATION)
@Name("myFilter")
@Install(precedence = Install.FRAMEWORK)
@BypassInterceptors
@Filter(within = { "org.jboss.seam.web.rewriteFilter" })
public class MyFilter extends AbstractFilter {
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        chain.doFilter(request, response);
    }
}

With the parameters within or around of the @Filter annotation, you can define when you filter will be called.

Disable JSESSIONID in Tomcat

Like PHP also the Servlet Containers try to attach a request to a session. If the client doesn’t support cookies it is realized via an suffix ;JESSSIONID= in every URL. Unfortunately this is not good in relation to SEO. The problem is that Tomcat doesn’t provide any configuration option to disable the use of JSESSIONID in URLs. So the only way is an own Filter, which disables the behaviour. You will find an example at: http://randomcoder.com/articles/jsessionid-considered-harmful
