Hello.

I am starting a project that combines both java and C code and I need it
to be compiled through ant (because the main aplicattion uses it).

I readed the webpage and what's my surprise to see that only version 
1.4supports jni (it's that true? higher versions doesn't support jni?)

Well, i tried to download version 1.4 and again I was surprised when I saw
that its de 1.6.2 (or it promtps it when i do ant -version):

    /usr/software/jakarta-ant-1.4/bin/ant -version
    Apache Ant version 1.6.2 compiled on January 3 2006


What's happening there is that the ant shell file is probably handing off to another version, whatever is in ANT_HOME or something jpackage installed. ant -diagnostics files more info.

1. Ant1.6 supports javah; please point out the URL where it said "1.4 only" and we'll fix it to "1.4 or later"
2. you do need ant-optional.jar with the javah task in it.

    BUILD FAILED
    /home/xar/Proyecto/temp/build.xml:4: Could not create task or type of
type: javah.

    Ant could not find the task or a class this task relies upon.

The build.xml couldn't be shorter:

    <project name="BOI" default="compile" basedir=".">
            <target name="compile">
                    <javac srcdir="." destdir="." nowarn="off" />
                    <javah destdir="." class="HelloWorld" />
            </target>
    </project>


run in -v mode for better diagnostics, perhaps.

Like Thomas says, once you start trying to compile the c++ code, you'll need the relevant tasks from ant-contrib.sf.net
