Spring IOC issues in MVC WebApplication with JSF integration

Question

Hello All,
I am getting null pointer exception while using spring's IOC feature in my application.
I have created one Spring + JSF Application in Eclipse ID given instruction at link http://www.javabeat.net/articles/39-integrating-spring-and-jsf-3.html.
This is working fine.
I tried to modify this code and instead of initializing the Map from the default constructor I have added below code in applicationContext.xml like
<util:map id="stockSymbolsAndValuesMap" map-class="java.util.HashMap">
<entry key="AAA" value="100"></entry>
<entry key="BBB" value="200"></entry>
<entry key="CCC" value="300"></entry>
<entry key="DDD" value="400"></entry>
<entry key="EEE" value="500"></entry>
</util:map>
and add this id's ref something like below.
<bean id="stockBean"
class="net.javabeat.articles.springjsf.introduction.StockValueFetcher">
<property name="stockBeanValue" ref="stockBean"></property>
</bean>
and modified the bean some thing like
public class StockValueFetcher {
private Map<String, String> stockSymbolsAndValues;
// with some getters and setters
while taking this map to my public String findStockValue() method I am getting null when I do stockSymbolsAndValues.containsKey(symbolName);.
I did this map injection in plain java main spring program and its working fine. So, in this case am I doing anything wrong or missing anything. Please guide me on this.
Thanks And Regards
Jaik

Hi Nithin,
We could solve this issue finally. The issue was HTTPS cookie persistence was not set at loadbalancer level. As we have two web servers behind load balancer, it seems once user authenticates with Azure AD, post back from Azure AD was happening to the server
other than the initial server which redirected the user to Azure AD intially.
Setting the HTTPS cookie persistence solved the issue.
However can you suggest if this is the only solution to fix this kind of issue. We don't want to enable this kind of sticky session on load balancer so if there is another way to fix it, it would be better.
