can I use org.apache.tomcat.dbcp.dbcp.BasicDataSource ?
Hy,
can I use "org.apache.tomcat.dbcp.dbcp.BasicDataSource" in place of
"org.apache.commons.dbcp.BasicDataSource"?
If yes I can avoid to put commons-pool and commons-dbcp in my webapp lib
folder.
Looking at Tomcat build.xml seems that the two names refers to the same
thing.
thank you
Edoardo

Charles advise to me that is a better policy to use with caution
internal Tomcat classes, indeed my question rises from this reason.
I don't want to save disk space (2 jars uses less space than few jpegs)
but I like to build polite application with no duplicate code. And less
dependences sounds like less probability to do mistakes.
If inside Tomcat library I can find the class that I must use is not
useful to insert another library in my application.
It is also true that my application with dbcp jars is more portable (not
a project requisite yet).
All more theoretical than practical.
thank you again

you sure can,
you can also use org.apache.tomcat.jdbc.pool.DataSource

Thank you for all the answers and the patience, I'll put the jars from
Apache commons in my application.

I have no experience with OpenJPA, but I would caution against direct use of Tomcat's internal classes, regardless of whether or not they match what commons-dbcp does. Just put the public jars in your webapp; disk space is cheap.
Note that some JDBC drivers also include their own optional pooling mechanism.

It's 6.0.18 (sorry). Under OS X (java 1.5) and Linux (java 1.6).
I am using opejpa and it seems to need an explicit connection-pool. I
did some test and I can achieve better performances if I use
connection-pools, no differences between tomcat-dbcp and "plain"-dbcp.

You do that by letting Tomcat manage the connection pool:

(Adjust the above link for the version of Tomcat you're using, which you didn't bother to tell us.)
