Developing a custom webapp with Alfresco embedded

I am writing a proof-of-concept web application that embeds Alfresco and uses its repository services API. Currently, I'm trying to flush out a few details.1. I have a simple servlet that grabs the application context and authenticates in the init() method, which will start up the embedded Alfresco

Regarding #2, if the application context is already loaded via a Spring WebApplicationContext (which is how the web client does things), you can use the following code to obtain a reference to it (and from there a reference to the service registry):

    ApplicationContext ctx = (ApplicationContext)request.getSession().getServletContext().getAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE);
    ServiceRegistry    reg = (ServiceRegistry)ctx.getBean("ServiceRegistry");

A minor simplification is to implement the ServletContextAware interface in your servlets and/or filters, and then follow the same steps above. I've not tried this myself yet.

Thanks for the tip! I have found that the web client does this slightly differently, using a spring method to grab the web application context:


WebApplicationContext wc = WebApplicationContextUtils.getRequiredWebApplicationContext(context);
ServiceRegistry serviceRegistry = (ServiceRegistry) wc.getBean(ServiceRegistry.SERVICE_REGISTRY);

Nice! I didn't know that that Spring API existed! 😉
