can not find jc1 gcj or jvgenmain after gcc install

[charfi asma <charfiasma@yahoo.fr>]

Hello,

I have pb with the java fe

I installed gcc 4.4.1 fron source and current gcc version from git ($ git clone 
git://crules.org/git/gcc-dev.git) but in both versions I can not compile java 
files

I looked for the java compiler gcj but I do not find an executable called gcj or 
jc1 (just like g++ or cc1plus for c++ front end)
Is there any configuration option to well install java fe other than 
--enable-languages=java ?

when I compile java file using gcj -save-temps Hello.java --main=Hello -v 2>&1 | 
grep ecj I get an empty .jar

[charfi@is010178 Hello]$ which gcj
which: no gcj in 
(/usr/bin:/bin:/usr/local/bin:/usr/X11R6/bin/:/usr/games:/usr/lib/qt4/bin:/export/home/charfi/bin:/usr/bin)



[charfi@is010178 Hello]$ which g++
/usr/bin/g++

thanks
