Hi all,
I would like to ask u, how can i utilize database connection in my web
service. I have one web service with more methods in it. Id like to create
database connection just once and not with each call (each operation works
with the same database connection) Is it enough to create this

If you deploy this service in Application Scope, then there will be one and
only one instance of this service throught out the life time of the
application.
This way you only create your database connection once.

Since only one instance of the Service is used to serve all requests, your
code needs to be able to handle concurrency.
As anthony mentioned you may need to either use a

Hi Deepal,
Thank you, it really looks like good idea to implement interface
ServiceLifeCycle and make database pool there or to store it in AxisService
Parameter. It s a pity there s no sample in Axis2 distribution for pooling
database connection in Axis Service and I havent found it also in net

What's the error? Could it be a class loader issue?

You said there are no errors, right?, However the fact that you can't
establish a connection to the db server is an error, so it s
initializations. To make
Axis2 call your implementation, you must identify it in the services.xml
file.
Hope this helps.

I didn't implement soap-web-services till now, so my generally

Dear All:
I've wrote a small servlet that extends AxisServlet.
This home-made servlet can get database connection from our connection
pooling mechanism.
The question is : When I write the java code of my service , how can I
get a database connection ? I find no way to send a database conne

because ThreadLocal doesn't define a getTMApp() method (the only way you could
invoke this method through the
ce and publish it.
