Problem in using the freetts for java in linux

Question

hi, i am not able to run the demo of the freetts library in my system. I have posted this on the forum of freetts but haven't got any reply yet. I am trying to run the HelloWorld demo, When i am running the following command,

ant -find demo.xml , 

i am getting 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 can see a jar file HelloWorld.jar in the freetts/bin folder but when i run :

java -jar bin/HelloWorld.jar

I get that unable to access the jar file, i even tried accessing it becoming a super user.

Please if someone has used the freetts ,help me on this. Thanks.
