Hi All,

I'm trying to use Flex 3's RemoteObject to connect to a java
application that connects to a MS Access database (JDBC) and
returns a value.



The problem is, everytime I try to connect to the db vie
RemoteObject I get a message in the Tomcat std-out log

"[Microsoft][ODBC Microsoft Access Driver] '(unknown)'.......



Also I have written a java application that use the same java
database classes in it works.

The database is also stored on the same machine as tomcat and
blazeDS.



Thanks

Well, you have to register a service you application. BlazeDS
is the application template you might want to start with.



Secondly if need to compile custom tags get the webtier.war
and follow the install notes to update your BlazeDS app. template.



Now coming to your topic - after you registered a service in
your remote configuration file. then you can call it the service
and get the data over in the flex component.



You don't need to get the connection over. The error you get
is that you may not have the driver into the right sport or the
database is not registered into the ODBC panel ?



If the call you made works fine and brings data into a jsp
let's say there is no reason not to get the data over via the
remote service.



Hope this helps!

Thanks,

I wrote a jsp file to test the connection and that didn't
work.

I think it has some thing to do with Tomcat 6.

I use the same jsp file and tested on another machine running
Tomcat 5.5 and

it worked with no problems.



Thanks for your help
