javac source and target default values
Hi,
I suspect that although I use JDK 1.6 to run ANT's javac task, the
source/target compatability level is 1.5 and not 1.6.
I know that I can -and should- specify them using the source and target
attributes, but I would like to know where from does ANT take the default
values for these attributes.
Can anybody provide this information?
Thanks,
Naaman

Hey Naaman,Ant uses whatever JDK JAVA_HOME is to.
if you type:
echo %JAVA_HOME%
on the command line, where does it point to?
Also do the following:
echo %PATH%
and see if there is any JDK 5\bin directory on the system path?

RE: javac source and target default values
Posted by nlif <na...@plimus.com>.
javap says: major version = 50 minor = 0
Anyway, I have other proof that it's compiling as 1.5, but what's bugging me
is where the defaults come from...

RE: javac source and target default values
Posted by "Toomey, Kevin H (ATS, IT)" <Ke...@thehartford.com>.
AFAIK, Ant doesn't supply default values. The default value are supplied
by Java, and the value is whatever version it is.
I think you should first go back to the beginning and confirm your
suspicions that you are creating 1.5 byte code with a 1.6 JDK.
Run a javap command against one of the classes you create (javap
-verbose this.package.myClass) and look at the "major version". 49=1.5,
60=1.6
Thanks,
Kevin
