  Hi:
  
  It appears as though your system does not have the 'uudecode' command, which is needed to create the jar file.

    It's hard to tell. Did you recompile all of Sphinx-4 after unpacking jsapi.jar? The build is set up to build only a subset of Sphinx-4 if jsapi.jar is not present.
    
    In addition, what command are you using to start hello world?

  ok i got i recompied sphinx and all those errors get absolved except one:
  
  rich@linux:~/development/sphinx4> java -mx256m -jar bin/HelloWorld.jar
  Exception in thread "main" java.lang.NoClassDefFoundError: edu/cmu/sphinx/util/props/PropertyException
  
  this file is located in the edu/cmu/sphinx/util/props
  
  rich@linux:~/development/sphinx4> ls edu/cmu/sphinx/util/props
  Configurable.java PropertyException.java Resetable.java
  ConfigurationManager.java PropertySheet.java SaxLoader.java
  CVS PropertyType.java Symbol.java
  doc-files RawPropertyData.java ValidatingPropertySheet.java
  package.html Registry.java
  
  this is very confusing to me in that it is there but get a class not found exception

    I'm stumped as well. I just pulled fresh sources from the CVS repository, extracted jsapi.jar, and then executed ant from the top level directory.
    
    java -mx256m -jar bin/HelloWorld.jar worked fine for me. :-(
    
    Maybe something didn't get built for you?
