Connections could not be acquired from the underlying database! Using Hibernate + c3p0 + Oracle 11g
14,794
Are using a very old version of c3p0? This issue should have been fixed as of c3p0-0.9.1.2, released in May 2007. Please upgrade to the current version, c3p0-0.9.5.2.
Upgrading to a more recent Oracle driver should help as well. By now I'd hope most vendors would support the holdability property.

i am currently having a issue with my environment related with some app that i use.
I'm running an application with hibernate, c3p0, spring, maven and it work normally when i connect to a SQL Server Database.
But when i tried to connect the application with any Oracle Database i get the following error:

(Driver etc..) and the same Oracle 11g XE version.
I already tried to rise the max number of connection on the database, reinstall Oracle, check if there are any port conflict but nothing works.
Obs: My application have 2 different modules, one for GUI and other to make all the application processing. The GUI part works fine, it connect to database with success, bit the other doesn't and i cant figure out how to solve this.

Lucas G over 8 yearsYour answer give me a light. I decided to delete my oracle drivers from everywhere, .m2 folder and oracle installation folder. Than download the drivers again and build the application. Now its working fine, so i believe the reason of the problem was some corrupted driver. Thanks for the help.
