关于如何在基于PHP的Web门户中访问Java + Xml应用程序的说明

Question

I Require a clarification on one Technical Implementation to check its feasible or not.

I have one VPS server which has a Java Environment and I have one more dedicated server which doesnot have a Java Environment where i have built my PHP based web application,

In the VPS environment I am planning to implement the XML based application using the Observer pattern with java and DOM Parsers and make that application available at say for example 123.124.125.65/XML_Works/Sample,xml file

Now My doubt is that: 1)is it possbile to access this application in dedicated Server where the java environment is not there. 2)if yes, then is it possible to access that java + XML application in IFrame in PHP based web portal.

Answer 1

1) No JVM = no java running on that machine
2) The most common solution I saw (and am using) is to externalize the java functionality you want as a web service or servlet and package it as a .war
Then use some web container such as tomcat to load that war and use a connector to connect calls to tomcat to your PHP server.

So the configuration I use is, Java as war, Tomcat as web container, Apache as PHP server and mod_jk connector for communication between servers.

Note that the mod_jk connector also supports other web servers.
