tomcat-dbcp interceptors
Hello Tomcat users,
I have couple of tomcat-dbcp related questions:
1) Can tomcat-dbcp be used outside of tomcat e.g. in non-web apps?
2) If yes, are all features available as when used within tomcat?
3) Most importantly are custom interceptors supported when tomcat-dbcp
is used outside tomcat?
4) Can custom interceptor influence/extend connection validation?
Would like not only to configure validation query but also to add
extra logic which would process result of the query.
5) Are there any examples, documentation, blog posts showing
implementations of custom interceptors?
Thanks in advance!
Regards,
Stevo.

Stevo,
OK, in the context of tomcat-jdbc, your questions do make more sense.
Glad you were able to find the answers.
BTW, I would strongly recommend tomcat-jdbc over DBCP. Been working
with it for a while and it's very nice.

Hello Daniel,
You're right, commons-dbcp and tomcat-dbcp seem to be same, I missed
tomcat-jdbc module which seems to provide extensions and judging by
the pom (see [1]) it depends only on tomcat-juli. I found the answers
at [2] and [3].
Thanks!

Stevo.

Yes, but tomcat-dbcp is exactly the same as commons-dbcp. You would
probably just want to use commons-dbcp.

It has the same feature set as commons-dbcp.

I'm not exactly sure what you are referring to with regard to the
interceptors. Which version of Tomcat are you using? How are you
configuring this within Tomcat?
