Getting the Seam context in a Filter

[nemya]

Hi,
I'm using a filter to do a conditional treatment on my pages. Is it possible(and how) to get the seam context in this filter? I want to have the return of a getter of a session bean in my filter.
Thank you

Use the context filter (rtfm) and then use Component.getInstance()

How can I use context filters?

Read the free manual =)

I put in web.xml:

but I have an exception:
java.lang.IllegalStateException: No active event context

<web:context-filter url-pattern="*.seam"/>

Someone to explain how to use the context filter.

Don't configure the context filter for standard Seam URL's (i.e. *.seam), you need to configure it for your custom servlet. Take a look at the seamspace example, it uses a context filter to provide a content servlet (ContentServlet.java) access to the Seam contexts for the purpose of returning binary image data.

The configuration for this is in web.xml:

<servlet>
 <servlet-name>Content Servlet</servlet-name>
 <servlet-class>org.jboss.seam.example.seamspace.ContentServlet</servlet-class>
 </servlet>

 <servlet-mapping>
 <servlet-name>Content Servlet</servlet-name>
 <url-pattern>/content/*</url-pattern>
 </servlet-mapping>

and in components.xml:

<web:context-filter url-pattern="/content/*"/>

Hi!
I did like in Seam Space and it works for all components except one (the one I need!), I found that the problem is the injecting of FacesContext so if I remove:

@In FacesContext facesContext;

it works...but I need it because I have to read an init parameter (that I put in web.xml).

How can I do?

thanks

FacesContext.getCurrentInstance();
