Setting up a datasource with WebSphere Liberty Profile 8.5 - jdbc

Question

My web app is getting a data source from JNDI with:
javax.naming.InitialContext ctx = new javax.naming.InitialContext();
javax.sql.DataSource ds = (javax.sql.DataSource)
ctx.lookup("java:comp/env/jdbc/db");
In the app's WEB-INF/web.xml, I have:
<resource-ref>
<description>DataSource</description>
<res-ref-name>jdbc/db</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
In the app's WEB-INF/ibm-web-bnd.xml, I have:
<web-bnd
xmlns="http://websphere.ibm.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://websphere.ibm.com/xml/ns/javaee http://websphere.ibm.com/xml/ns/javaee/ibm-web-bnd_1_0.xsd"
version="1.0">
<virtual-host name="default_host"/>
<resource-ref name="jdbc/db" binding-name="jdbc/db"/>
</web-bnd>
In WebSphere Liberty Profile's server.xml, I have (keeping on the relevant parts):
<server description="new server">
<featureManager>
<feature>jsp-2.2</feature>
<feature>jdbc-4.0</feature>
</featureManager>
<library id="oracle-lib">
<fileset dir="lib" includes="ojdbc5_g.jar"/>
</library>
<dataSource jndiName="jdbc/db" jdbcDriverRef="oracle-driver" type="javax.sql.DataSource">
<jdbcDriver libraryRef="oracle-lib" id="oracle-driver"/>
<connectionManager numConnectionsPerThreadLocal="10" id="ConnectionManager" minPoolSize="1"/>
<properties user="user" password="password"
url="jdbc:oracle:thin:#//db-server:1521/db"/>
</dataSource>
</server>
When the app attempts to get the datasource from JNDI, it fails with the following error:
CWNEN0030E: The #Resource factory encountered a problem getting
the object instance jdbc/oracle binding object. The exception message was:
failed to resolve jdbc/oracle to javax.sql.DataSource:
javax.naming.NameNotFoundException:
Intermediate context does not exist: jdbc/oracle
What I am missing here?

WebSphere server.xml
<server>
<featureManager>
<feature>jndi-1.0</feature>
<feature>jdbc-4.1</feature>
</featureManager>
<httpEndpoint id="defaultHttpEndpoint"
host="localhost"
httpPort="9080"
httpsPort="9443" />
<library id="oracle-lib">
<fileset dir="lib" includes="ojdbc6_g.jar"/>
</library>
<dataSource jndiName="jdbc/oracle">
<jdbcDriver libraryRef="oracle-lib"/>
<properties.oracle user="orbeon" password="password"
url="jdbc:oracle:thin:#//localhost:1521/orbeon"/>
</dataSource>
<application name="orbeon" location="war/orbeon" type="war">
<classloader commonLibraryRef="oracle-lib"/>
</application>
</server>
WEB-INF/ibm-web-bnd.xml
<web-bnd version="1.0"
xmlns="http://websphere.ibm.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://websphere.ibm.com/xml/ns/javaee http://websphere.ibm.com/xml/ns/javaee/ibm-web-bnd_1_0.xsd">
<virtual-host name="default_host"/>
<resource-ref name="jdbc/oracle" binding-name="jdbc/oracle"/>
</web-bnd>
WEB-INF/web.xml
<resource-ref>
<res-ref-name>jdbc/oracle</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
Resource injection (instead of web.xml + ibm-web-bnd.xml):
#Resource(lookup = "jdbc/oracle")
DataSource ds;

Answer 2

we use DB2 on Liberty 8.5.5 and we have in server.xml
<dataSource id="db2" isolationLevel="TRANSACTION_READ_COMMITTED" 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.db2.jcc databaseName="DB2T" portNumber="21020" serverName="db2t.lvm.de"/>
<containerAuthData password="{xor}KzspMC04" user="tdvorg"/>
</dataSource>
Maybe helps that.

Answer 3

In my case, the solution below works fine for me.
I created a "Generic project" in Eclipse called "Resources". Inside this project I created a file dataSource.xml with following content:
<server>
<dataSource id="ccm" jndiName="jdbc/ccm" type="javax.sql.DataSource">
<jdbcDriver id="oracle-driver" libraryRef="oracle-lib"/>
<connectionManager id="ConnectionManager" minPoolSize="1" numConnectionsPerThreadLocal="10"/>
<properties.oracle password="password" url="jdbc:oracle:thin:#128.1.30.150:1521:ccmdes" user="ccm"/>
</dataSource>
<library id="oracle-lib">
<fileset dir="C:\Oracle\product\10.1.0\Client_1\jdbc\lib" includes="ojdbc14_g.jar"/>
</library>
<jdbcDriver id="oracle" libraryRef="oracle-lib"/>
</server>
And I drag and drop this file for server configuration in Eclipse or create the line in server.xml:
<include location="${shared.config.dir}/dataSource.xml"/>
The file server.xml was like this:
<server description="new server">
<!-- Enable features -->
<featureManager>
<feature>jsp-2.3</feature>
<feature>adminCenter-1.0</feature>
<feature>jdbc-4.1</feature>
<feature>jndi-1.0</feature>
<feature>servlet-3.1</feature>
</featureManager>
<httpEndpoint host="localhost" httpPort="9080" httpsPort="9443" id="defaultHttpEndpoint"/>
<applicationMonitor updateTrigger="mbean"/>
<!-- Define your admin user name and password -->
<quickStartSecurity userName="admin" userPassword="password"/>
<!-- Define a keystore for the HTTPS port -->
<keyStore id="defaultKeyStore" password="Liberty"/>
<!-- Allows remote file access for config changes -->
<remoteFileAccess>
<writeDir>${server.config.dir}</writeDir>
</remoteFileAccess>
<!-- <applicationMonitor updateTrigger="mbean"/> -->
<webApplication id="TestPage" location="TestPage.war" name="TestPage"/>
<webApplication id="MonitoriaAtendimento" location="MonitoriaAtendimento.war" name="MonitoriaAtendimento"/>
<include location="${shared.config.dir}/dataSource.xml"/>
</server>
