im trying to get a controller to return a view through a Expression Language-Filter, but have no idea on how to get jersey to use EL for filtering a view.

View with EL-tags:

<html>
    <title>%{msg}</titl开发者_运维技巧e>
</html>

Controller:

@GET
@Produces("text/html")
public Response viewEventsAsHtml(){
    String view=null;
    try {
        view=getViewAsString("events");
    }catch(IOException e){
        LOG.error("unable to load view from file",e);
        return null;
    }
    Response.ResponseBuilder builder=Response.ok(view, MediaType.TEXT_HTML);
    return builder.build();
}

How would one go about in order to get the controller to replace the ${msg} part in the view by some arbitrary value?

If you are using Jersey then it provides the ability to return a Viewable from the Resource which will process jsp by default.

Example Jersey Resource

@Path("/patient")
public class PatientResource {
    @GET @Path("/{patientId}") @Produces(MediaType.TEXT_HTML)
    public Viewable view(@PathParam("patientId") int patientId) {
        return new Viewable("/patient.jsp", Integer.toString(patientId));
    }
}

Example patient.jsp
