Version of JDK to develope the Applet VS version of JRE on client'sbrowser

[Krist]

Hi gurus,

If I develope and compile an Applet using JDK jdk 1.5.0_xx.

What happen if it is run by client using Browser with JRE Newer than
1.5.0_xx ?

What happen if it is run by client using Browser with JRE Older than
1.5.0_xx ?

Thank you for your help,

It's supposed to work.

1.5.0_xx ?

It won't work (older like 1.4, etc)

What "java coder" said. However, if you use JDK 1.5, and add a -target
flag to your compiler, then you can specify that the Applet *will* run
on older JRE versions, like 1.4 and 1.3. Note there may be source
incompatibilities that you will have to adapt to (like classes that were
introduced in 1.5 and aren't present in earlier versions).

Check out the -target flag on the javac command line docs.

It will work fine on 1.6
It will fail on 1.4

Java is like most other development.

If developed at version X then it will run on versions >= X but
not on version < X.

Java is slightly better than most other development tools
because it has -source and -target where you can use a newer
Java version to develop for older Java versions.

According to the statistics at:
http://www.statowl.com/java.php
you should cover most with 1.5 + 1.6 support.
