Problem using freetts for java on linux

Question

I cannot run a demo of the freetts library on my system. I posted this on the freetts forum, but have not received a response yet. I am trying to run a HelloWorld demo. When I run the following command,

ant -find demo.xml 

I get the following output:

Searching for demo.xml ...
Buildfile: /home/pranay/Downloads/freetts-1.2.2-bin/freetts-1.2/demo.xml
make_lib_dir:
compile_demo_util:

BUILD FAILED
/home/pranay/Downloads/freetts-1.2.2-bin/freetts-1.2/demo.xml:86: srcdir      "/home/pranay/Downloads/freetts-1.2.2-bin/freetts-1.2/demo/util" does not exist!
Total time: 0 seconds

I see the jar file HelloWorld.jar in the freetts / bin folder, but when I run:

java -jar bin/HelloWorld.jar

I get that I can’t access the jar file, I even tried to access it by becoming superuser.

Please, if someone used freetts, help me with this. Thank.
