servlets

Below is the servlet code: private ArrayList<String> ticketLookup(String tkt) { Connection con = null; Statement st = null; //StringArray msga = new StringArray(); ArrayList<String> msga

问题 i'm on the architectural phase of a big project and i've decided to use hbase as my database, and will use map/reduce jobs for my processing so my architecture works totally under hadoop. The thing is i also need to implement some REST, SOAP API's some web pages too so i was thinking is there any servlet container that runs on top of hadoop so that my system stays redundant and distributed without worrying about a secondary cluster machenism(since i allready setup one for hadoop).

问题 We've got some Pure Servlets (pure Java classes following the Servlet API, no framework) that we'd like to include in a project that relies heavily on the Spring Framework.

问题 I have created one filter which is working fine for all requests which my application gets, for this I have written new class ResourceRequestWrapper which extends HttpServletRequestWrapper to modify requests. For example, when request comes for /ui/tx/images/abc.png I have overridden getServletPath() , getRequestURL() and getRequestURI() methods of HttpServletRequestWrapper to modify text of incoming request to /txeditor/images/abc.png . Now, I have created virtual directory in JBoss/Tomcat
