I have Two projects, CarpoolDB and Carpool.
CarpoolDB : contains backend stuff and has
carpool-application-context.xml
<context:annotation-config />
<context:component-scan base-package="com.onmobile" />
<context:property-placeholder location="classpath:server.properties" />
server.properties
cm.db.driverClassName=com.mysql.jdbc.Driver
cm.db.url=jdbc:mysql://localhost:3306/carpool1
cm.db.username=abc
cm.db.password=xyz
I make a jar of carpoolDB and place in Carpool Application
Carpool: contains UI thing and for backend contact carpoolDB jar and has
carpool-application-context1.xml
<import resource="classpath:carpool-application-context.xml"/>
<context:annotation-config />
<context:component-scan base-package="com.onmobile.carpool.authentication" />
spring-servlet.xml
<context:property-placeholder location="classpath:carpool.properties" />
<context:annotation-config />
<context:component-scan base-package="com.onmobile.carpool.controller, com.onmobile.carpool.util" />
carpool.properties
cm.email.sender.mail.smtp.host=mail.on.com
Now, I have one class com.onmobile.carpool.util.EmailSender, it has one property smtpHost and want the value to get injected by Spring using @Value but it is not getting injected.
@Controller
public class EmailSender {
public static final Log logger = LogFactory.getLog(EmailSender.class);
@Value("${cm.email.sender.mail.smtp.host}")
private String smtpHost;
}
I am getting error as
java.lang.IllegalArgumentException: Could not resolve placeholder 'cm.email.sender.mail.smtp.host'
carpool.properties is present in src folder.
Why it is not picking the cm.email.sender.mail.smtp.host from carpool.properties file. is there any relation with properties file present in jar file.
Actually properties file is loaded as I can't see in logs like file not found but field is not getting autowired.

cm.email.sender.mail.smtp.host=mail.on.com
I am trying to inject value of cm.email.sender.mail.smtp.host in EmailSender "smtpHost" property way mentioned above, when i read it it says null. other properties like cm.db.driverClassName etc get properly injected in carpool-application-context1.xml.
I am attaching the snap containing location for configuration files
