Here is my_app.xml:

<Context path="/myapp>
    <Resource name="jdbc/myapp" auth="Container" type="javax.sql.DataSource"
         maxActive="100" maxIdle="30" maxWait="10000"
         username="mauro" password="xxx" driverClassName="org.postgresql.Driver"
         url="jdbc:postgresql://svsopsql01.mydomain.com:5432/my_app"/>
</Context>

and here is my_app1.xml

<Context path="/myapp1>
    <Resource name="jdbc/myapp1" auth="Container" type="javax.sql.DataSource"
         maxActive="100" maxIdle="30" maxWait="10000"
         username="mauro" password="xxx" driverClassName="org.postgresql.Driver"
         url="jdbc:postgresql://svsopsql01.mydomain.com:5432/my_app1"/>
</Context>
