Mixing Seam and GWT using the Seam Context-filter

I am trying to add a GWT page to an existing Seam2 application. In the GWT page I am making use of GWT RPC to fetch data from the server. I need to give that GWT servlet access to the Seam conversation context. For this, I am attempting to use the context-filter discussed in section 29.1.4.8 of the Seam2 user guide and making my GWT RPC servlet a Seam component. The user guide specifies that the the filter requires that the Seam conversation id be set on the request sent to the servlet. I am not sure how to do this with a RPC call, as it is made through a proxy and I don't think I have access to the request itself. Is there any way to set a request parameter while using RPC or am I stuck building a request manually? Also, does anyone have experience mixing GWT and Seam using the context-filter?开发者_运维百科 I am having trouble finding successful examples.

you don't need a filter to get access to the seam conversation context with GWT RPC. Have a look at the following link: http://code.google.com/p/gwt-seam/wiki/GettingStartedGWTRPC
