Re: Error Accessing JBI Container from JSR181 Component - Is it Possible?

[Guillaume Nodet <gn...@gmail.com>]

Until there is a better way to do that, you can try:


    public void setContext(ComponentContext context) {
        this.context = context;
        try {
            Field field = context.getClass().getDeclaredField("context");
            field.setAccessible(true);
            Object smxContext = field.get(context);
            field = smxContext.getClass().getDeclaredField("container");
            field.setAccessible(true);
            JBIContainer container = (JBIContainer) field.get(smxContext);
            ...
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
