Q:

Connecting to h2 database with Glassfish

I'm developing a web-app using Glassfish application server.
I have installed H2 DB and now trying to define a connection pool in glassfish but when trying to ping the DB it fails.
Here is what I did:

Installed H2 DB and created a new DB (server mode).
I added an H2 maven dependency in my pom.xml:
<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <version>1.3.166</version>
</dependency>

Copied H2 jar file (h2-1.3.166.jar) to my glassfish lib: C:\glassfish3\glassfish\lib
Loggd on to glassfish admin gui and created the following jdbc connection:

Resource type: javax.sql.DataSource
Database Driver Vendor: H2
Datasource Classname: org.h2.jdbcx.JdbcDataSource

My "additional properties" are:

user:  my_db_user
password:  my_db_password
url:  jdbc:h2:tcp://localhost/~/my_db_name;AUTO_SERVER=TRUE

When I try to ping this connection it fails with message:
Ping Connection Pool failed for myCpool. Class name is wrong or classpath is not set for : org.h2.jdbcx.JdbcDataSource Please check the server.log for more details.
The full log says:

Have I missed something?
Any help is appreciated!

A:

The ClassNotFoundException: org.h2.jdbcx.JdbcDataSource means the H2 JDBC driver is not in the classpath. I don't know Glassfish very well, but it seems it's not in the classpath. It seems similar problems occurred with other database drivers, for example MySQL (the .jar file needs to be added to /glassfish/domains/[domainname]/lib/ext)
You need to use a different database URL:
jdbc:h2:~/my_db_name;AUTO_SERVER=TRUE

As described in the documentation, the automatic mixed mode does not require or work with server URLs (URLs starting with jdbc:h2:tcp://)
