Solution
You can download the library from Hibernate official website
Or
Add the dependency in Maven’s pom.xml
<dependency>
<groupId>hibernate-commons-annotations</groupId>
<artifactId>hibernate-commons-annotations</artifactId>
<version>3.0.0.GA</version>
</dependency>
P.S You may need to include the JBoss repository in order to download the Hibernate common annotation library.
<repositories>
<repository>
<id>JBoss repository</id>
<url>http://repository.jboss.com/maven2/</url>
</repository>

I had to replace hibernate-annotations version from 3.2.0ga to 3.3.0.ga
Then I started getting
org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘sessionFactory’ defined in ServletContext resource

I had to add hibernate commons dependency
org.hibernate
hibernate-commons-annotations
3.2.0.Final
This can be found in the below repository
Central repository
http://repo1.maven.org/maven2
After this Issue was resolved I started getting this error..
Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.(Z)V
Caused by: java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.(Z)V
Was getting this issue because of having different versions of asm jars.
There was asm.jar conflict…
mvn dependency:tree -Dverbose -Dincludes=asm.. command helped to find out.. the jar conflict.

org.hibernate-3.2.1 dependency was looking for asm- 1.5.3 jar
and cglib-2.1 dependency was looking for asm-3.1..
I was missing the asm 3.1 jar dependency that was required for cglib
Hope this information would be useful for some one..
