untar problem with mod_jk

Hi All,

I am trying to configure Apache to run Java using mod_jk (jakarta tomcat
connectors).

I tried downloading the binary from
http://jakarta.apache.org/builds/jakarta-tomcat-connectors/jk/release/v1.2.4
/bin/linux/, but the file is mod_jk.so-ap2.0.46-rh72.
Reading the howto, I assume the file is a tar, but my tar doesn't recognise
the as such.

I also tried rebuilding from the source, but this gave errors as well:
[root@gateway jk]# ant
Buildfile: build.xml

detect:
[echo] -------- jakarta-tomcat-connectors --------

prepare:

BUILD FAILED
file:/usr/local/jakarta-tomcat-connectors-jk-1.2.4-src/jk/build.xml:139:
Warning: Could not find file
/usr/local/jakarta-tomcat-connectors-jk-1.2.4-src/coyote/build/lib/tomcat-co
yote.jar to copy.

These files are not there, so maybe an error in build.properties? Here the
first lines:
# Directory where tomcat5 is installed
#tomcat5.home=/usr/local/jakarta-tomcat-4.1.27

# Directory where catalina is installed. It can
# be either 4.0 or 4.1
#tomcat40.home=/usr/local/jakarta-tomcat-4.1.27

# If you want to build/install on both 4.0
# and 4.1, set this to point to 4.0 and 'catalina.home'
# to point to 4.0
# ( most people need only the first, but developers should
# have both )
tomcat41.home=/usr/local/jakarta-tomcat-4.1.27

# Directory where tomcat3.3 is installed
#tomcat33.home= ../../jakarta-tomcat/build/tomcat

# Location of Apache2, Apache1.3, Netscape, IIS
apache2.home=/usr/local/apache

Some info:
Redhat 8.0
Apache, just downloaded and rebuild 2.0.47
Tomcat same, version 4.1.27
Tar version: tar (GNU tar) 1.13.25

Any idea what I'm doing wrong?
Thanks for any help
