JerseyServletModule and resteasy RequestScopeModule - conflicting bindings

[Aseem]

Hi,

Receiving "A binding to XXX was already configured at YYY" due to using JerseyServletModule and RequestScopeModule from resteasy.

All the classes that RequestScopeModule binds to a provider are already being bound in JerseyServletModule while creating the injector. Not installing RequestScopeModule is not an option with the current code I'm working with since it enables the objects to be referred using @Context annotation at runtime (and its a third party).

Code looks like:

@Override

protected Injector getInjector()

{

    return Guice.createInjector(new JerseyServletModule()

    {

        @Override

        protected void configureServlets()

        {

            install(new AbcModule());

            //params, filters and other modules

            serve("/*").with(GuiceContainer.class, params);

        }

    });

}

AbcModule.configure:

@Override

protected void configure()

{

    install(new RequestScopeModule());

}

Client code uses @Context UriInfo uriInfo; which is always null in case I do not install RequestScopeModule (since its already bound but not available in the Context). And installing it gives conflicts on all of the classes for which the providers are being created when inserting into the Context of the request.

Is there a way to resolve these conflicts (possibly by removing bindings from JerseyServletModule() and letting guice rebind those from RequestScopeModule)?

Thanks

Have you tried using AbcModule as an override module?:

@Override
protected Injector getInjector()
{
    return Guice.createInjector(Modules.override(new JerseyServletModule()
    {
        @Override
        protected void configureServlets()
        {
            serve("/*").with(GuiceContainer.class, params);
        }
    }).with(new AbcModule()));
}
