Hello,
I am working on a client server application involving TOMCAT as Web
server, MySQl as the DB and combination of JSP, Servlet, and JavaBeans
to access and write Data back.
There is another piece of the project (out side my scope of
development) that
writes to the Same MySQL tables and make changes to the data.
How do I write a Trigger/Store Procedure or any such mechanism that
would throw an event that the external Java Beans would catch and take
action like, fetch the changed data....
I am sure this is a very commom issue in application development and
there maybe some patterns that I need to follow.
Any suggestion will be appriciated.
Thanks

Thanks for the response Steve,
The other piece of project that writes the data is in C++ :-)
I fond an article to use JNI so the C++ object can call Java object
when the data is changed. This Java object can be a listener that
all my beans could register to and listen for appropriate event and
update data.
I think I wil take that route.
Thanks
Tushar

I suppose there might be a way to do what you're asking, but the usual model for an app with requirements like that would be to add a middle-tier that is used by both front-ends. I know you said the other piece was outside your scope of development, but perhaps you need to broach the isssue to whomever has the authority that it may be time for the 3-tier idea.

in oracle, one can rmi and socket to an external server. Otherwise,
one can always poll :)

Hi Guys,
I just want to hear your understanding of Java Beans. I mean it doesn't just expose properties (for parameters) right? Java beans must be able to do what variables can't. i need feedbacks please. Thanks

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

For most users, this new feature is actually very convenient. If you want to control the update process,...
