title: Communication between jsp and java application
body: <p>My project requirement is to develop a website which interacts with a mysql database and a java application which continuously runs on the server. user is on some remote computer he sends a request to the java application by executing a jsp code on the server, the jsp code waits for the application to send the information back. once the jsp recives the info. it sends a request to database. The is a special type of database built just because of limitations of a database and my project requirements. Please tell me how the request are sent i.e. what part of java will help me do this. </p>
  
  <p>some link that have the same info but not exact <a href="https://stackoverflow.com/questions/1680898/communication-between-two-separate-java-desktop-applications">Communication between two separate Java desktop applications</a>.    </p>
  
  <p>EDIT: my question is.... what should i use in a jsp page such that i will be able to get info. from the application which stores data in a special form of datastructure. For now I dont want to talk to database. I just want to interact with a running application.</p>
  
  <p>for example there is a program on the server which returns sum of two numbers which waits for someone to give it input. now my jsp sends two numbers to the application which adds the two numbers and gives back the sum to the jsp page. now jsp page code can do anything which is not my concern for now.  </p>
