"JavaMailSenderImpl cannot be resolved to a type" after switching to 4.0.1 Release

I have developed Spring MVC app with 3.1.1 Framework Version, now I want to switch to 4.0.1. I am using Maven to handle all the dependencies.So when I change the version in `pom.xml`, I get compilation error `JavaMailSenderImpl` could not be resolved to type. Also I am not able to locate package `org.springframework.mail.javamail.JavaMailSenderImpl` in the jars.But from docs it looks like this package is not removed in latest version. I tried cleaning the project & building again but didn't helped me. So any idea what am I doing wrong here? This is the URL to docs Below is part of `pom.xml` - ``` <properties> <hibernate.version>4.1.3.Final</hibernate.version> <spring.version>4.0.1.RELEASE</spring.version> <spring.security.core.version>3.1.1.RELEASE</spring.security.core.version> <spring.security.version>3.1.1.RELEASE</spring.security.version> <google-guava.version>12.0</google-guava.version> <joda-time.version>2.1</joda-time.version> <slf4j.version>1.6.4</slf4j.version> <h2.version>1.3.167</h2.version> <jasper.version>4.7.0</jasper.version> <commons.digester.version>2.1</commons.digester.version> <commons.collections.version>3.2.1</commons.collections.version> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> <exclusions> <exclusion> <artifactId>commons-logging</artifactId> <groupId>commons-logging</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-jpa</artifactId> <version>1.1.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> <!-- Spring Security --> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-core</artifactId> <version>${spring.security.version}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-web</artifactId> <version>${spring.security.version}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-config</artifactId> <version>${spring.security.version}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-taglibs</artifactId> <version>${spring.security.version}</version> <type>jar</type> <scope>compile</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.security.core.version}</version> </dependency> <!-- Java Mail Dependency --> <dependency> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> <version>1.4.7</version> </dependency> <dependency> <groupId>javax.activation</groupId> <artifactId>activation</artifactId> <version>1.1.1</version> </dependency> </dependencies> </project> ```
