Issue is with classpath only that you are not able to see the imports correctly, also i would recommend to use the below code snippet for intializing proxies.

Create a class HibernateUtils and call it's static method.

public class HibernateUtils {

    public static <T> T initializeAndUnproxy (T entity) {
        if (entity == null) {
            return null;
        }

        if (entity instanceof HibernateProxy) {
            entity = (T) ((HibernateProxy) entity).getHibernateLazyInitializer().getImplementation();
        }

        return entity;
    }


}

Things to consider :

Have you include hibernate jar files (especially the required jars) in your lib folder ?

antlr-2.7.7.jar
commons-collections-3.2.1.jar
dom4j-1.6.1.jar
javassist-3.12.1.GA.jar
hibernate-core-4.0.1.Final.jar
hibernate-commons-annotations-4.0.1.Final.jar
hibernate-jpa-2.0-api-1.0.1.Final.jar
jboss-logging-3.1.0.CR2.jar
jboss-transaction-api_1.1_spec-1.0.0.Final.jar

this file is from hibernate you will download and it will have required folder inside lib.

If yes :

Right click the import which contains error , and click Fix project setup and missing jar files will be automatically included.
