Multiple JRE's

rebellad · 2006-07-24 11:09:00

I have developed a Java application in net beans with JDK 1.4.2 and am using it with JRE 1.4.2, my problem is that the user of the machine wants to install a new app that requires JRE 1.5.2. My question is can I set my app to use 1.4.2 or will it automatically use the JRE related to the JDK it was developed with??

If you install the 1.5 jre it will probably be the default jre for all applications. 1.5 is backwards compatible, so your code will continue to run fine on 1.5. Alternatively, just modify your startup script for your app to use the 1.4 jre, or in netbeans you should be able to specify the jre to use when there is multiple ones installed.
