Hi,

I'm developing an application which uses Hibernate for OR Mapping and c3p0 for connection pooling. Starting the application from Eclipse and from a batch file works fine on the computer on which I'm actually developing. But after installing the application on a new computer (which has no internet connection) c3p0 hangs with the following error message and no connection to the database could be established:



I have used the same batch file to start the application.

Hibernate version: 3.0.5
c3p0 version: 0.9.0
Name and version of the database you are using: Oracle 10.1.0.2
Hibernate configuration:



On my development computer I'm using Java 1.5.0_01 on the new computer is the newest version of the Java runtime installed (1.5.0_05). I'm not sure if this is of matter. The database has the same configuration on both computers.

Best regards,

hi,

i was looking recently at the same error on a test environment. i simply forgot to install the database.

is it possible to connect to the db, with the same login/password as hibernate, with another tool?

chrigi,

I have installed the same database version on both machines and I'm able to connect to the database with a SQL query tool.

My first thought was that there is something missing in the classpath due to Eclipses strange classpath handling but the fact that the same batch file is not working on the new machine is invalidating my suspicion.

this error is generated by c3p0. if you change the connection pool temporarily it might output a more specific error and give you a hint.

chrigi,

it is in fact a database problem - as you assumed. I can reproduce exactly the same message on my old machine if I'm shutting down the Oracle instance and try to start the application. I'm a little bit astonished because I'm able to connect to the database using a query tool.

Nevertheless I have to check what has gone wrong with the database on the other machine tomorrow.

Many thanks and best regards,
tfe
