It's supposed to work. > What happen if it is run by client using Browser with JRE Older than > 1.5.0_xx ? It won't work (older like 1.4, etc)

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.

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. Arne |
