Re: DBCP connection pool and validation query
Thanks Armin... now I know what the problem is... I need to format my brain and reinstall it! I'AM SO STUPID! the validationQuery attribute must be set on the element and NOT on the element. When it is correctly set, then it works as expected and reported by you. Sorry for making anybody loose time, however if somebody else has the same problem, then yeah, just look where you set the validationQuery ;) cheers Danilo Armin Waibel wrote: Hi Danilo, Danilo Tommasina wrote: Hi everybody, We have following problem.: We are using the DBCP connection factory, we've set a validation query, however we never see this query beeing executed.
