Execute Sphinx4 HelloWorld in terminal(Ubuntu)

[Senjam Shantirani]

I have installed Sphinx4 in ubuntu and executed the HelloWorld demo using Eclipse IDE successfully. I want to execute the same in ubuntu terminal.I tried executing the following in the terminal in the path where my project was created:

COMPILATION: The command below throws no error and creates 'HelloWorld.class'.
javac -classpath sphinx4 /home/shanti/Desktop/VOX/src/edu/cmu/sphinx/demo/helloworld/HelloWorld.java

RUN TIME: The command below throws error, it was used reffering to an instruction from a site.

java -classpath ../lib/sphinx4.jar ../lib/WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.jar edu.cmu.sphinx.demo.helloworld.HelloWorld

[I took the path from helloworld.Manifest which lists:

Main-Class: edu.cmu.sphinx.demo.helloworld.HelloWorld
Class-Path: ../lib/sphinx4.jar ../lib/WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.jar ]

ERROR SHOWN BELOW--

Exception in thread "main" java.lang.NoClassDefFoundError: /home/shanti/Desktop/VOX/src/edu/cmu/sphinx/demo/helloworld/HelloWorld

Could not find the main class: /home/shanti/Desktop/VOX/src/edu/cmu/sphinx/demo/helloworld/HelloWorld. Program will exit.

Please let me know why the errors are happening and how to solve them. Also I am not sure if the command being use to run the application is correct, please advice.I am new to JAVA, ANT and Sphinx4.

Thanks in advance,
Senjam Shanti

Entries in class path are separated by ':', not by space. The command line must be something like this:

  java -cp lib/sphinx4.jar:lib/WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.jar:bin/HelloWorld.jar edu.cmu.sphinx.demo.helloworld.HelloWorld

Since class path is hardcoded in manifest inside the jar, you can also run the following:

   java -jar bin/HelloWorld.jar

Please note that those commands must be run from the top source folder, not from the bin folder.
