Configuration trash

Just create this entry to keep various configurations in a central place. I am going to update it in the future - when it is necessary.
Tomcat datasource definition (H2 database):
server.xml:

... 
<GlobalNamingResources>
... 
<Resource name="jdbc/h2" 
                  auth="Container"
                  type="javax.sql.DataSource" 
                  factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
                  driverClassName="org.h2.Driver"
                  url="jdbc:h2:tcp://localhost/mem:db1"
                  <!-- for in-memory DB: -->
                  <!-- url="jdbc:h2:mem:test;DB_CLOSE_DELAY=-1" -->
                  username="xxx" 
                  password="xxx" 
                  initialSize="5"
                  minIdle="2"
                  maxIdle="10"
                  maxActive="20"
                  maxWait="15000"

/>
</GlobalNamingResources> 

EDIT: Please remember about:

validationQuery="select 1"
validationQueryTimeout="10"
validationInterval="10000"
testOnBorrow="true"

context.xml:

<Context> 
...    
<ResourceLink global="jdbc/h2" name="jdbc/h2" type="javax.sql.DataSource" />
</Context> 

web.xml:

    <resource-ref>
    <description>DB Connection</description>
    <res-ref-name>jdbc/h2</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
    </resource-ref>
