I'm getting issues with creating an in memory table, using H2 database, and being able to access it outdoors from the JVM it's produced and running in.

The documentation structures the url as jdbc:h2:tcp://<host>/mem:<databasename>

I have attempted many combinations, but merely cannot obtain the remote link with work. Is feature working, can anybody produce the particulars of methods they used this.

You may take a look at In-Memory Databases. For any network connection, you'll need a host and database title. It appears as if you want jdbc:h2:tcp://localhost/mem:db1 or jdbc:h2:tcp://127.0.0.1/mem:db1
