Hi friends, when we use a higher version, but want that our application run also on lower version of JDK also, then we use c:\>javac -target 1.3 hello.java here file name is hello.java and currently we are useing JDK1.5 and we want byte code of hello.java that is compatable to jdk1.3. This command does not run on jdk1.5 but this run on jdk1.4.
I want to know that -target option command runs or not on jdk1.5.
Just type java in command prompt. You will get the useage help. When i tried in 1.5 version i did not find -target as option. Since you have 1.4 try out in 1.4 version if you get -target option. If you get this, then it is clear that JDK1.5 don't support -target option....
