How do I update ANT in eclipse? [message #59907]

Hi,

I read this on internet
"Previous versions of ant had a problem with the javah target under
JDK 1.4, so you must use 1.6.1 or later."
( http://www.mozilla.org/projects/blackwood/webclient/release- notes/
2_0_alpha_2-detail.html)

And since I have a problem using these lines in eclipse's ANT

</javac>
<javah destdir = "." force = "yes" verbose = "true"
classpath = ".">
<class name = "mypackage.MyClass"/>
</javah>

With the following error

BUILD FAILED: ...\build.xml:98: Error starting javah:
java.lang.ClassNotFoundException: com.sun.tools.javah.Main

I thouhgt I might need to update my version of ANT, but I don't know
how.

Is there anyone that knows what's wrong?
Thanks

~ Daniel

Always start by telling us which version of Eclipse you are using so I can
give you the specific instruction set

For the 3.1 stream:
Window>preferences>Ant>Runtime>Ant Home

Set it to the install of Ant you wish to use.

For an FYI:
Eclipse 3.0 ships with Ant 1.6.1
Eclipse 3.0.1 ships with Ant 1.6.2
Eclipse 3.0.2 ships with Ant 1.6.2
Eclipse 3.1 is in the process of being moved to Ant 1.6.3
