Thank you Christoph , but in this how-to there isn't any example for SQL

Well, no. But did you expect someone else to do all the work for you ?
These are your options :
1) considering that SQL Server is a proprietary product of Microsoft, contact the
Microsoft helpdesk (or the available on-line Microsoft documentation) to help you using it
with Tomcat/java/jdbc
2)
a) find a working java jdbc driver for SQL Server, install it as indicated in
the page
b) read the documentation of this driver, to find out how to adapt any of the 3 examples
provided, to that specific driver
c) try it out
d.1) if it works, consider submitting your configuration to this list, so that someone can
perhaps add it as example #4 on the Tomcat website, to help future people with a similar issue
d.2) if it does not work, come back to this list, and show your configuration and what
problem you have (e.g. logfile). Someone may then be able to help you further.
Additional tip : "it show me error to connect to database .." is not really enough for
anyone to seriously help you. You need at least to provide :
- the platform under which this is happening (Linux, Windows, ..)
- the (full) version of java that is used
- the (full) version (7.x.y) version of Tomcat
- the original error messages, as they appear on the screen or (better) in the
logfile
The more accurate and detailed data you provide immediately, the more you are likely to
get a useful response. Otherwise, a lot of people who may be capable or willing to help,
would be discouraged in advance, because they have to start by asking you all these
questions and wait for you to answer them.
Additional tip # 2 : you are probably in Europe, and there are a lot of Tomcat experts on
this list, based in the US. So maybe if you provide that information now, you may have
tomorrow morning some useful responses.

Oggetto: Re: jdbc check available database
Hello guys,
I’ve SQL Server database with Tomcat 7 and, when I restart only
database,
webapps on Tomcat didn’t works , it show me error to connect to
database ..
In webapp context I use jdbc driver for connect, so there is a kind of
method for retry to connect to database when it return available?
Hi,
I suggest to use a DataSource instead of dealing with jdbc connections on
your own.
see:

Regards,
Christoph
