[antlr-interest] newbie stringtemplate NoClassDefFoundError problem

[Pete Siemsen]

My translator recognizes input, so now I'm trying to emit output.   
I'm using string templates for the first time.  The test rig looks  
like this:

import org.antlr.runtime.*;
import org.antlr.stringtemplate.*;
import java.io.*;

public class cimmof2java {
         public static void main(String[] args) throws Exception {

                 String inputFileName = args[0];
                 String stgFileName = args[1];
                 String outputDirectoryName = args[2];

                 StringTemplateGroup templates = null;
                 // Load contents of template group file into  
"templates"
                 try {
                         FileReader groupFileR = new FileReader 
(stgFileName);
                         templates = new StringTemplateGroup 
(groupFileR);
                         groupFileR.close();
                 } catch (IOException FileNotFoundException) {
                         System.out.println("couldn't open string  
template group file: " + stgFileName);
                         System.exit(1);
                 }

                 // Open an input file stream from the given file name
                 CharStream input = new ANTLRFileStream(inputFileName);
                 // Create a lexer that feeds from the input file stream
                 cimmof2javaLexer lexer = new cimmof2javaLexer(input);
                 // Create a stream of tokens fed by the lexer
                 CommonTokenStream tokens = new CommonTokenStream 
(lexer);
                 // Create a parser that feeds off the token stream
                 cimmof2javaParser parser = new cimmof2javaParser 
(tokens);
                 // Give the parser the string templates
                 parser.setTemplateLib(templates);
                 // Begin parsing at rule mofSpecification
                 cimmof2javaParser.mofSpecification_return retVal =
                     parser.mofSpecification(outputDirectoryName);
                 StringTemplate output = (StringTemplate) 
retVal.getTemplate();
                 // Emit the translation
                 System.out.println(output.toString());
         }
}

When I give it the name of an existing .stg file, it gives

    Exception in thread "main" java.lang.NoClassDefFoundError: antlr/ 
TokenStream
         at cimmof2java.main(cimmof2java.java:16)

If I give it a .stg file name name of a file that doesn't exist, it  
gives

    couldn't open string template group file: bogus.stg

So something happens in the creation of "templates".  I'm not real  
strong with Java class location problems.  What's the problem finding  
antlr/TokenStream?  Any help appreciated.
