Cannot find datasource in Java Adapter in IBM MobileFirst - db2

Question

I have created a DataSource in MobileFirst server.xml:
<dataSource jndiName="jdbc/QAIWDB2">
<jdbcDriver libraryRef="DB2Lib"/>
<properties databaseName="QAIWPRD" password="pass" portNumber="99999" serverName="xyz.com" user="user"/>
</dataSource>
When I am trying to access it from a Java Adpater I am getting an error while deploying the adapter
Adapter deployment failed: An object could not be obtained for name
jdbc/QAIWDB2.
The code in Java Adapter is
static DataSource ds = null;
static Context ctx = null;
public static void init() throws NamingException {
ctx = new InitialContext();
ds = (DataSource)ctx.lookup("jdbc/QAIWDB2");
}

Try the DB2 JNDI definition proposal mentioned in this answer: https://stackoverflow.com/a/17851124/1530814.
Of course, change the values to yours...
<dataSource jndiName="jdbc/db2" type="javax.sql.DataSource">
<jdbcDriver>
<library>
<fileset dir="/usr/lib/java/ibm-db2-universal-driver" includes="db2jcc4.jar, db2jcc_license_cisuz.jar, db2jcc_license_cu.jar"/>
</library>
</jdbcDriver>
<properties databaseName="DB2T" portNumber="21020" serverName="db2t.lvm.de password=" ... " user=" ... "/>
</dataSource>
