Which JRE is being used?
Recently I was assigned to take care of a web application developed by JSP, Javascript, struts & EJB. The source codes are compiled into different WAR, JAR and EAR files by using JDK 1.4.2_03. The App Server being used is JBOSS 3.2.3. I hava a lot of questions concerning the application in my mind. Here are some of them, Can anyone please help:
(1) From the Java Forums, I know that java applications need JRE to run. But I don't see the web application force me to install any JRE when I try to access it via IE6. Why?
(2) Is there any way (e.g. bat script) that I can know which JRE the web application is using? Can you provide me with some code samples?
(3) I read an artricle somewhere saying that JRE can be bundled to a web application. How can I now whether the JRE 1.4.2_03 is being bundle with my web application?
(4) Since the application is compiled by JDK 1.4.2_03, is this a must to use the JRE 1.4.2_03 only?
Thanks
