Just a quick check whether you have the Postgresql JDBC jar under tomcat/lib OR WEB-INF/lib?

had the same problem a few weeks ago,if you install tomcat7 on debian weezy using the paket manager its not completely the same as if you download tomcat from tomcat.apache.org, if i remember the pooling libraries are different.

download the binary distribution apache-tomcat-7.0.52.tar.gz from tomcat.apache.org and copy the /lib directory from this tar.gz to /var/lib/tomcat7/lib

this is only a workaround to get rid of this error, better would be to leave paket management behind and use the complete binary distribution from tomcat.apache.org

kind regards,
hannes

Hi Hannes,
thanks for this hint! I finally managed to solve this weird problem.
I replaced the catalina*.jar and tomcat-dbcp.jar (provided by debian in /usr/share/tomcat7/lib/) with the ones provided by the apache-tomcat binary distribution.

Thanks a lot!
-Andreas.

Hi all,

I have the same problem with a very similar install on Ubuntu server LTS (14.04) and the solution described above has also helped me (i.e. copying catalina.jar and tomcat-dbcp.jar from the Tomcat binary dist). Could anyone out there shed some light on the reasons? I would think the JARs inside the package libtomcat7-java should result from the same source code.

Best regards, Valentin
