How to inject an object to the portlet scope?

erezharari Apr 10, 2008 12:55 AM

in general the portlet knows very little on the containing portal.
i need a way to 'inject' and object (my own) to the portlet and save it in a request/session/application scope.
how can that be done?

in JBoss Portal 2.7 you will be able to use portlet filters defined by JSR 286 to achieve that result.

Meanwhile a way that may work is to use a servlet filter in your application and configure it using dispatcher tag such as:

<filter-mapping> <filter-name>MyFilter</filter-name> <url-pattern>/jbossportlet</url-pattern> <dispatcher>INCLUDE</dispatcher> </filter-mapping>

I think this should work but I have not tested it. The "/jbossportlet" url pattern is the special servlet injected at runtime in the portlet application to make the portlet container dispatch in the war file containing your portlets.

that's odd.. i need to define a filter-mapping without defining a filter element? that works? and then, what objects would the filter inject into my portlet? in request scoped attributes? i'm sorry, it's not clear to me..

MyFilter is implicitely the filter you will implement, sorry for not being more explicit.
