Please use the google group to ask questions - thanks.

Sure. Where is the CheckDataSource example?

In the "Getting started" section of this site: http://www.avaje.org/ebean/getstarted_props.html

Thanks.

Ok, I didn't see anything wrong in that page.

Can you show the full stack trace of the error?

The error you are getting looks like one of the properties in the ebean.properties file is not correct (or that the value is incompatible with the version of Ebean you are using).

So, if you post up the full stack trace and the Ebean version you are using then that will likely point to the issue.

Thanks, Rob.

Hi Rob,
I have same problem with Fabric when i tried the example CheckDataSource above. This is full stack trace that i received from Eclipse:

I use Ebean 2.5.1

Can you help me? Thank you.
Can you help me? Thank you.

Note that your problem is not the same - you are getting a different error (NPE at DefaultServerFactory.java:399).

So it looks to me like there is not a jdbc driver specified. So you need to check your ebean.properties file. Perhaps you are missing the databaseDriver entry?

# example

datasource.h2.username=sa
datasource.h2.password=
datasource.h2.databaseUrl=jdbc:h2:mem:tests;DB_CLOSE_DELAY=-1
datasource.h2.databaseDriver=org.h2.Driver
datasource.h2.minConnections=1
datasource.h2.maxConnections=25
datasource.h2.heartbeatsql=select 1
datasource.h2.isolationlevel=read_committed
