Tomcat 8, axis2 webservices aar, spring jndi not bound in context - windows

Question

I have been working on an issue where JNDI name is not found in the context an axis2 webservice is running. This issue is only in Tomcat 8 when I use spring.
Some details: (I will provide the elements that are relevant)
1. services.xml
<service name="ScoreService" class="com.bpl.ws.service.ScoreServiceInitializer">
<description>Simple test service</description>
<parameter name="ServiceObjectSupplier" locked="false">org.apache.axis2.extensions.spring.receivers.SpringAppContextAwareObjectSupplier</parameter>
<parameter name="SpringBeanName" locked="false">scoreService</parameter>
2. server.xml:
<Host name="localhost" appBase="webapps" xmlBase="C:\Applications\apache-tomcat-8.0.30-windows-x64\context"
unpackWARs="true" autoDeploy="true">
Context.xml
<JarResources className="org.apache.catalina.webresources.DirResourceSet"
base="C:\Applications\apache-tomcat-8.0.30-windows-x64\commonLib" webAppMount="/WEB-INF/lib"/>
4.JNDI resource in the context file:
<Resource name="jdbc/ADS" auth="Container"
factory="com.bpl.ws.EncryptedJdbcDataSourceFactory"
type="javax.sql.DataSource"
driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:#xxxxxxx.com:3203/xxxx"
username="xxxxx"
password="xxxx"
initialSize="10"
logAbandoned="false"
maxActive="20"
maxIdle="10"
maxWait="10000"
removeAbandoned="true"
removeAbandonedTimeout="120"
jdbcInterceptors="QueryTimeoutInterceptor(queryTimeout=10)"
testOnBorrow="true"
validationInterval="30000"
validationQuery="Select 1 from dual"/>
As shown in services.xml file listing, I am using an initializer class and the code to load the spring context looks like this:
4.ScoreSerivceInitializer
public void startUp(ConfigurationContext ignore, AxisService service) {
System.out.println("SCORESERVICE:: Starting up..");
DataSource ds;
ClassLoader cloader = service.getClassLoader();
Thread.currentThread().setContextClassLoader(cloader);
System.out.println("SCORESERVICE:: spring context starting up");
spContext = new ClassPathXmlApplicationContext(new String[] {"DST-Context.xml"},false);
spContext.setClassLoader(cloader);
try {
spContext.refresh();
spring context.xml (DST-Context.xml)
The DST-Context.xml entry looks like this:
<bean id="applicationContext"
class="org.apache.axis2.extensions.spring.receivers.ApplicationContextHolder" />
<bean id="datasource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>java:comp/env/jdbc/ADS</value>
</property>
</bean>
Tomcat log:
[WARN] Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'datasource' defined in class path resource [DST-Context.xml]: Invocation of init method failed; nested exception is javax.naming.NameNotFoundException: Name [java:comp/env/jdbc/ADS] is not bound in this Context. Unable to find [java:comp].org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'datasource' defined in class path resource [DST-Context.xml]: Invocation of init method failed; nested exception is javax.naming.NameNotFoundException:
Name [java:comp/env/jdbc/ADS] is not bound in this Context. Unable to find [java:comp].
Without changing anything in the configuration, if I changed the ScoreServiceInitializer to do this:
initCtx = new InitialContext();
envCtx = (Context) initCtx.lookup("java:comp/env");
ds = (DataSource)
envCtx.lookup("jdbc/ADS");
Everything works. As you see here I don't use any spring and the jndi datasource is in context.
If I deploy the code with spring config in Tomcat 7, it works fine.
The spring context seems to be the issue but have been looking at it for a while and cant seem to figure out why Tomcat 8 has a different behavior compared to Tomcat 7. I know that Tomcat8 has changed some behavior in terms of how the Resources are configured and the dbcp is now dbcp2 and I have updated config files accordingly.
Any help is greatly appreciated. Please let me know if any other info is required.

#bplso I had the same issue when I upgrade tomcat7 to tomcat8.5 on a axis2 project, try the steps given in image. It may be solve your issue.
!
Step 1: Specify the connection resource in server.xml inside <GlobalNamingResources> like
<Resource name="jdbc/name"
global="jdbc/name"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
auth="Container"
type="javax.sql.DataSource"
username="xxx"
password="YYY"
driverClassName="net.sourceforge.jtds.jdbc.Driver"
url="jdbc:jtds:sqlserver://host:port/dbname"
maxTotal="10"
maxIdle="10"
maxWaitMillis="10000" />
Step 2: Specify the resource reference in web.xml inside the <web-app> like
<resource-ref>
<description> This is a reference to the global Resource for SQL database connetion. </description>
<res-ref-name>jdbc/name</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
Step 3: Create a context.xml file and paste it in your project/META-INF/ path as below
<?xml version=.1.0 encoding="UTF-8.?>
<Context>
<ResourceLink name="jdbc/name" global="jdbc/name" type="javax.sgl.DataSource"
</Context>
