OpenCMIS SQL Parsing Question

[Robert.Williams3]

Hello,

I am new to CMIS and I am presently looking at handling query functionality in 
our CMIS Server,.  To this end, I am attempting to implement the code specified 
 in section 1.7 entitled "Parsing a CMIS Query" in chapter 14 of the text CMIS 
and Apache Chemistry in Action.  While this example code seems very straight 
forward, I am getting the following error when invoking it for the CMIS SQL 
statement:  Select * from cmis:document where cmis:name = 'My_Document-0-0'.  I 
have tried variations such as ending the SQL statement with a semicolon and 
others, but the result has been the same.

         <faultstring>Query String has illegal tokens after end of statement: 
[@15,63:63='&lt;EOF>',&lt;-1>,1:63]</faultstring>

Based on debugging that I've performed, the CMIS SQL statement looks like it is 
getting into the code unaltered, but it goes off the rails somewhere.

The following is the QueryUtil::getWalker() method that is failing, 
specifically the highlighted code:

    public static CmisQueryWalker getWalker(String statement) throws 
RecognitionException {
        CharStream input = new ANTLRStringStream(statement);
        TokenSource lexer = new CmisQlStrictLexer(input);
        TokenStream tokens = new CommonTokenStream(lexer);
        CmisQlStrictParser parser = new CmisQlStrictParser(tokens);
        CommonTree parserTree; // the ANTLR tree after parsing phase

        query_return parsedStatement = parser.query();
        if (parser.hasErrors()) {
            throw new CmisInvalidArgumentException(parser.getErrorMessages());
        } else if ( tokens.index()!=tokens.size() ) {
            throw new  CmisInvalidArgumentException("Query String has illegal 
tokens after end of statement: " + tokens.get(tokens.index()));
        }

        parserTree = (CommonTree) parsedStatement.getTree();

        CommonTreeNodeStream nodes = new CommonTreeNodeStream(parserTree);
        nodes.setTokenStream(tokens);
        CmisQueryWalker walker = new CmisQueryWalker(nodes);
        return walker;
    }

I did notice that the QueryUtil class is deprecated.  Further, as a result of 
digging around, I have discovered an OpenCMIS Query Parser Example directory.  
The parsing done in these files uses the QueryUtilStrict class and seems to be 
done a little differently.  Should I use this example code for CMIS SQL parsing 
instead of the example in the text?

Thanks in advance for any and all assistance!
