Use asadmin with option create-jdbc-connection-pool first:
asadmin create-jdbc-connection-pool --datasourceclassname org.apache.derby.jdbc.EmbeddedDataSource --property databaseName=\$\{com.sun.aas.instanceRoot\}/databases/tutegodb:connectionAttributes=\;create\=true tutegoPool
Use asadmin again to install the actual JNDI name:
asadmin create-jdbc-resource --connectionpoolid=tutegoPool jdbc/tutego
To remove the pool and all attached JNDI names:
asadmin delete-jdbc-connection-pool --cascade tutegoPool
