This is very misleading. You need to remember that these elements are
dependent on how they are implemented in the interpreter. Utilizing the
<object> tag still means that there would be a necessity to create the class
which would access the database. You're also forgetting that in most cases
this is going to be a distributed system with the vxml pages being fetched
by the gateway on the OTHER side of a firewall. I seriously doubt your
approach would work in the real world. Better to utilize <submit> with a
servlet or JSP on the application server side. 
 
There are no shortcuts to this. As mentioned earlier, exceptions, rollbacks,
etc. need to be properly handled. This can only be done as server side code.

Not necessary, Nitin and Shridhar, you can use either <script> or <object>
for database access.

Hi Shridhar,
 
According to my knowledge there are no tags in VXML for database acess.
Customized tags are not possible as VXML  as such is a XML schema.
For database access you will have to call asp or jsp pages and dynamically
create vxml pages.
 
Thanks and Regards.

Hi, 

Are there any tags in voiceXML that can make program read data from database
by generating the queries dynamically? 

If yes then what are those tags? 

If no then is it possible to have customized tags (say "dbread") in
voiceXML? viz. 

<prompt> 

Your account balance is <dbread table='account' field='balance'/> 

</prompt> 



Is this feasible? OR we have to always submit to next asp or jsp or whatever
and generate the vxml with account balance information dynamically? 

If it is feasible then... 

do the vxml interpreters available today can support customizable tags? Like
if a custom tag is found the interpreter should hand over the control to the
application to take necessary actions. 



Regards, 

Shridhar
