Yes. that's the right page. On the lower-right is a link "Create jdbc connection pool"
I just created a jdbc connectin pool, AND a associated datasource for sql server. I was able to see the corresponding elements in domain.xml:
<jdbc-connection-pool datasource-classname="com.microsoft.sqlserver.jdbc.SQLServerDataSource" res-type="javax.sql.DataSource" name="SQLPool">
<property name="ApplicationName" value="Microsoft SQL Server 2005 JDBC Driver" />
<property name="Encrypt" value="false" />
<property name="LastUpdateCount" value="true" />
<property name="LockTimeout" value="-1" />
<property name="LoginTimeout" value="0" />
<property name="PacketSize" value="8000" />
<property name="Password" value="password1" />
<property name="PortNumber" value="1433" />
<property name="ResponseBuffering" value="full" />
<property name="SelectMethod" value="direct" />
<property name="SendStringParametersAsUnicode" value="true" />
<property name="ServerName" value="localhost" />
<property name="TrustServerCertificate" value="false" />
<property name="URL" value="jdbc:sqlserver://" />
<property name="User" value="user1" />
<property name="XopenStates" value="false" />
</jdbc-connection-pool>
<jdbc-resource pool-name="SQLPool" jndi-name="jdbc/mysql" />
