HI,

I want to integrate my web application with different versions of jdk say 1.4 , 1.5 and 1.6. Kindly how to get these 3 environments installed and running and associate different application with different versions.
Also in that case would i need to do any changes in the classpath environment variable. If yes what changes would be required.


Regards,
Amit

you might want to first install all 3 jdks.... Change JAVA_HOME system variable to point to desired jdk version... and put the %JAVA_HOME%/bin directory of the desired version preceding to all other path variables....

and well i don't know how you will run different web applications concurrently using 3 jdks...

I think I should install only JREs(instead od JDKs as I just hv to use different environments of executing different applications) and point the applications to respective JREs in the jDeveloper IDE.
Am I right?? Anyone please suggest
