I’m developing a java application which reads a continuously written a file of recordsets

  • 0

I’m developing a java application which reads a continuously written a file of recordsets (800.000.000 records per month), bulk reading data from files and calls a web service to read also data. These data should be stored in a database (a huge database). The next feature I’m going to add is a web service, which can be called from other applications to add or receive (predefined queries [maybe the running time of the method/query is about 1 or 2 minutes]) records. Additionally to web service I want other application written in c#, c++, etc. to be able to connect (I thought about protocol buffers or apache thrift).
And at least it should offer a way to administrate the application (i though about a web site)

In my opinion it should be a server application. But should I develop a server on my own (opening sockets, etc.), a Java EE or are there any other “server frameworks” (may be a combination of jetty, sockets, etc.)?

    just divide and conquer:
    One solution can be using tomcat:

    function 1) create a thread which reads the file. then you can define a context listener within the web.xml

    function 2) Look at java.util.Timer or, for more robust functionality, look at a third party product like Quartz.

    function 3a) There are a lot of WS frameworks availabe. Use google to find tutorials

    function 3b) Google for Asynchronous Web Service or Asynchronous Support in Servlet

    function 4) AFAIK Thrift has a build-in TServlet. I think Tomcat and Google Protokoll Buffers is also possible

    function 5) Offering web sites is one of tomcats main functions
