title: Local H2 Server-Client connection with DB running in memory
body: <p>I have two independent Java apps which I would like to communicate with each other through an in-memory H2-DB.  In theory very straight forward, but I cannot get the connection to work.</p>
  
  <p>What I am trying to do:
  I create an in-memory DB executing <code>jdbc:h2:mem:test</code>.
  With the client(s), I try connecting to it.  I tried <code>jdbc:h2:tcp://localhost/~/test</code> and similar connection strings, but all without success.</p>
  
  <p>Is it possible to connect to an in-memory DB?  What should the connection strings look like to make this work?  Thanks a bunch.</p>
