问题 I'm not able to understand why my simple configuration of DispatcherServlet to implement Spring MVC does not work.

iOS 10 Custom URL Scheme no longer working

只愿长相守 提交于 2019-12-25 08:31:51
问题 I have an app with a custom URL scheme set up, and I added the URL to the LSApplicationQueriesSchemes array in the Info.plist. If I go straight into Safari on the device or simulator and hit myapp:// then the app will open up. However, I have an externally hosted website with a servlet that calls response.redirect("myapp://") and when this is called, the app does not open. The servlet redirect works in iOS 9 and below. What changed in iOS 10 so that this call no longer works? It's odd that if

How to pass parameters to JSP using response.sendRedirect?

问题 I really need to use response.sendRedirect() method because my JSP(search.jsp) page is actually calling for a servlet <jsp:include page="/searchServlet" /> and in my searchServlet if I use the forward method (to the same page) I get a weird error (maybe because I'm calling it and forwarding all the time, I din't find the reason yet..) however I need to read an attribute in my JSP(search.jsp) page with a simple message like "Please provide valid data" However since I'm using my response to

Accessing servlet scoped beans from another thread

吃可爱长大的小学妹 提交于 2019-12-25 07:19:01

Normally the instances of the object are created for each request, so they don't clash, but if I pass the object to another thread to use the session beans, the same object is used and it

What I am looking to do is have a setup where I can reuse the servlet context XML but just have it pick up the correct properties file based on the servlet being setup.
