Hi,
I followed Jake's advice.
He got me moving in the right direction.
Here is what I saw.
I edited and then I inspected my build.xml file:
[root@localhost ant]# cat build.xml
<?xml version="1.0"?>
<!-- A simple build.xml file -->
<project name="build.xml 01" default="vizant" basedir=".">
<target name="vizant">
<taskdef name="vizant" classname="net.sourceforge.vizant.Vizant" classpath="/CD/vizant.jar"/>
<vizant antfile="build.xml" outfile="build.dot"/>
<exec executable="dot" failifexecutionfails="false" resultproperty="graphvizSuccess!">
<arg line="-Tpng build.dot -o build.png"/>
</exec>
<fail unless="graphvizSuccess!">
You probably need to install GraphViz which is a native program,
not a Java library >>>
http://www.research.att.com/sw/tools/graphviz/
</fail>
</target>
</project>
[root@localhost ant]#
Next, I ran ant:
[root@localhost ant]# ant
Buildfile: build.xml
vizant:
[exec] Error: Could not find/open font : Times in
/usr/X11R6/lib/X11/fonts/TrueType:/usr/X11R6/lib/X11/fonts/truetype:/usr/X11R6/lib/X11/fonts/TTF:/usr/share/fonts/TrueType:/usr/share/fonts/truetype:/usr/openwin/lib/X11/fonts/TrueType:/usr/X11R6/lib/X11/fonts/Type1:/usr/common/share/fonts/ttf
BUILD SUCCESSFUL
Total time: 1 second
[root@localhost ant]#
At first, I was not sure how to troubleshoot this although it was
obvious that I got the vizant tag recognized by ant.
I inspected the directory for build.dot:
[root@localhost ant]# ls -l build.dot
-rw-r--r-- 1 root root 59 Oct 1 17:25 build.dot
[root@localhost ant]# cat build.dot
digraph "G" {
graph ["rankdir"="LR",];
"vizant";
}
[root@localhost ant]#
Good; ant created build.dot for me.
I tried the "dot" command line which ant was trying:
[root@localhost ant]# dot -Tpng build.dot -o build.png
Error: Could not find/open font : Times in
/usr/X11R6/lib/X11/fonts/TrueType:/usr/X11R6/lib/X11/fonts/truetype:/usr/X11R6/lib/X11/fonts/TTF:/usr/share/fonts/TrueType:/usr/share/fonts/truetype:/usr/openwin/lib/X11/fonts/TrueType:/usr/X11R6/lib/X11/fonts/Type1:/usr/common/share/fonts/ttf
[root@localhost ant]#
I studied my X-windows setup:
[root@localhost ant]# which xterm
/usr/X11R6/bin/xterm
[root@localhost ant]# cd /usr/X11R6
/usr/X11R6
[root@localhost X11R6]# find . -name '*Times*' -print
./man/man3/XtLastTimestampProcessed.3x.gz
[root@localhost X11R6]#
I saw no evidence of a "Times" font which might be tucked away in a corner somewhere.
I studied the dot executable.
[root@localhost X11R6]# dot -h
dot: option -h unrecognized
Usage: dot [-Vv?] [-(GNE)name=val] [-(Tlso)<val>] <dot files>
-V - Print version and exit
-v - Enable verbose mode
-Gname=val - Set graph attribute 'name' to 'val'
-Nname=val - Set node attribute 'name' to 'val'
-Ename=val - Set edge attribute 'name' to 'val'
-Tv - Set output format to 'v'
-lv - Use external library 'v'
-ofile - Write output to 'file'
-q[l] - Set level of message suppression (=1)
-s[v] - Scale input by 'v' (=72)
-y - Invert y coordinate in output
[root@localhost X11R6]#
I found some online documentation on "dot":
http://www.graphviz.org/cgi-bin/man?dot
I enhanced my "dot" command line:
[root@localhost ant]#
[root@localhost ant]# dot -Nfontname="cour" -Tpng build.dot -o build.png
[root@localhost ant]#
Oh boy; no error message.
I looked at build.png with my mozilla browser; it showed me a pretty
ellipse containing the string "vizant".
I then went back and enhanced my build.xml file and then ran ant.
[root@localhost ant]# cat build.xml
<?xml version="1.0"?>
<!-- A simple build.xml file -->
<project name="bikle build.xml 01" default="vizant" basedir=".">
<target name="vizant">
<taskdef name="vizant" classname="net.sourceforge.vizant.Vizant" classpath="/CD/vizant.jar"/>
<vizant antfile="build.xml" outfile="build.dot"/>
<exec executable="dot" failifexecutionfails="false" resultproperty="graphvizSuccess!">
<arg line="-Nfontname=cour -Tpng build.dot -o build.png"/>
</exec>
<fail unless="graphvizSuccess!">

</project>
[root@localhost ant]# ant
Buildfile: build.xml
vizant:

[root@localhost ant]# ls -l build.dot build.png build.xml

Sure, how about this...
1. Download:
http://umn.dl.sourceforge.net/sourceforge/vizant/vizant.jar
2. Either put vizant.jar in ANT_HOME/lib or create a property called
"vizant.jar" and use it like I have below in the "classpath" attribute for
the taskdef.
3. Run the following target (modified based on what you decide in #2)....
<target name="vizant">
<taskdef name="vizant" classname="net.sourceforge.vizant.Vizant"
classpath="${vizant.jar}"/>
<vizant antfile="build.xml" outfile="build.dot"/>
<exec executable="dot" failifexecutionfails="false"
resultproperty="graphvizSuccess!">
<arg line="-Tpng build.dot -o build.png"/>
</exec>
<fail unless="graphvizSuccess!">

http://www.research.att.com/sw/tools/graphviz/
</fail>
</target>
4. If you get the "fail" message, download the native graphviz program for
your platform and make sure the executable is in your system path.
After doing the above, everything should work for you.
