Hi, I am trying following code from the Chatter workbook but it is throwing error below. Any suggestion?

private static void displayNewsFeed() throws Exception {

System.out.println("Querying for status updates...");

QueryResult queryResults = connection.query

("SELECT Id, Type, CreatedDate, CreatedBy.name, Body FROM NewsFeed WHERE Type= 'UserStatus' ORDER BY CreatedDate DESC, ID DESC LIMIT 10");

if (queryResults.getSize() > 0) {

for (SObject s : queryResults.getRecords()) {

System.out.println(s.getChild("NewsFeed").getField("Body") );

}

}

}

^

Exception in thread "main" [InvalidFieldFault [ApiQueryFault [ApiFault exceptionCode='INVALID_FIELD'

exceptionMessage='

CreatedDate, CreatedBy.name, Body FROM NewsFeed WHERE Type= 'UserStatus'

ERROR at Row:1:Column:47
