title: Does simply installing the JDK on a webserver suffice for running Java web app?
body: <p>I have Java code that works on my desk top...its a simple app that grabs stuff from a database does something to it and outputs a list.</p>
  
  <p>This is for a consumer facing site and ultimately i want to pass the list on to PHP to use to furnish a page. </p>
  
  <p>I understand that I can do that with thrift and thats the current plan.</p>
  
  <p>But the question is whether I need some special server besides just the JDK to run the java end of things given the fact that it is being used purely for data processing?  Why or why not?</p>
  
  <p>How does JRE/JDK handle different users trying to access user-specific data at the same time given that php has to grab that info from the same java application? how does the java program know the difference?</p>
  
  <p>Thanks alot for your help!</p>
