I am not an expert in voicexml, so take my answer with a grain of salt :)

This looks good. I would consider using "else if" also note the first
parameter to playAndrecognize is TRUE indicating that the next parameter is
a uri to an audio file. If it is false the next parameter is assumed to be
text to be synthesized.
Then in the else if block, set the audioUri to a the audio file of your
choice.
String audioUri;
boolean PromptIsUri = true;
RecognitionResult r =
sClient.playAndRecognizeBlocking(PromptIsUri ,audioUri,grammar, false);
if ((r != null) && (!r.isOutOfGrammar())) {
for (RuleMatch rule : r.getRuleMatches()) {
if ((rule.getTag().equals("QUIT")) &&
(rule.getRule().equals("main"))) {
stopFlag = true;
this.getContext().dialogCompleted();
else if ((rule.getTag().equals("WEATHER")) &&
(rule.getRule().equals("main"))) {
//logic to figur out which audio file to
use in the the next playAndRec command
audioUri = file:///prompts/a.wav
}
}

It is not recognizing anything. It only recognizes what is in the grammar.
The prompt is trying to indicate what is in the grammar. It is a dumb
parrot that only knows a few words :)

Sorry, I meant to add an option to the demo to show how you can use a
pre-recorded prompt rather than TTS. I will add it to the next release.

localhost is probably ok if zanzibar and asterisk are on the same machine.
You can put the real host name or ip address of the zanzibar machine to be
safe.

Not sure if it should be at the end of mainmenu, can you send the main menu
dialplan?
I am very sorry, but the doc has a mistake and there is a bug in the code.
This section is partially correct
type|applicationName
where: type is either "beanId" "className" or "vxml"
So if you want to use the classname option instead of basic, use "classname"
The bug is that you must use "classname" in all lower case.
exten =>
1,n,SIPAddHeader(x-application:classname|org.speechforge.apps.demos.Parrot)
if you still have the bean "Parrot" defined in your context.xml file, you
can also use this instead (again case is important)
exten => 1,n,SIPAddHeader(x-application:beanId|Parrot)
<bean id="Parrot"
class="org.speechforge.apps.demos.Parrot"
singleton="false">
<property name="prompt">
<value>You can start speaking any time. Would you like to hear
the weather, get sports news or hear a stock quote? Say goodbye to
exit.</value>
</property>
<property name="grammar">
<value>file:../../demo/grammar/example-loop.gram</value>
</property>
</bean>

This is not really used unless you are transfering calls. I do not believe
you are doing this, so no worries about this config.

Sorry, but another issue with the docs. This is also called the
configuration file. It is basically a spring config file that is passed in
on te command line to the main zanzibar program. So look at the shell
script that you are using to start zanzibar (probably asteriskConnector.sh)
and check this line. In this case the context or config file is
pbxconfig.xml
CONFIG=file:../config/pbxconfig.xml

I think you are very close. The issue is with your dialplan. Probably your
placement of the three statements you describe in section 6. above.
