ClassNotFound Expection when loading beans in Grails

I have a jar file which has the beans defined in applicationContext.xml. I have added the jar file to the lib directory and also modified my build config to

runtime "content:content-examiner-data:1.0"

I have defined the beans in the resource.groovy as follows

beans = {

importBeans("classpath*:/applicationContext.xml")

}

The bean definitions are as follows

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:mongo="http://www.springframework.org/schema/data/mongo"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo-1.1.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd">

    <mongo:mongo host="localhost" port="27017" />


    <bean class="org.springframework.data.mongodb.core.MongoTemplate"
        id="mongoTemplate">
        <constructor-arg ref="mongo"></constructor-arg>
        <constructor-arg value="documents"></constructor-arg>
    </bean>
    <mongo:db-factory id="mongoDbFactory" dbname="database" mongo-ref="mongo"/>
  <mongo:mapping-converter id="converter" />

  <bean id="gridTemplate" class="org.springframework.data.mongodb.gridfs.GridFsTemplate">
    <constructor-arg ref="mongoDbFactory" />
    <constructor-arg ref="converter" />
  </bean>

  <bean id="ceMongoStore" class="gov.ic.isso.ce.service.mongoimpl.CEStorageMongoImpl">
    <constructor-arg ref="mongoTemplate" />
    <constructor-arg ref="gridTemplate" />
    <constructor-arg value="cedocs" />
  </bean>
</beans>

I get an error as follows when running the app with run-app option

 Error 2013-02-07 16:08:24,806 [localhost-startStop-1] ERROR context.GrailsContextLoader  - Error executing bootstraps: Cannot find class [gov.ic.isso.ce.service.mongoimpl.CEStorageMongoImpl] for bean with name 'ceMongoStore' defined in URL [jar:file:/C:/development/projects/sentrytrunk/Latest/fc/content-examiner-web/lib/content-examiner-data-1.0.jar!/applicationContext.xml]; nested exception is java.lang.ClassNotFoundException: gov.ic.isso.ce.service.mongoimpl.CEStorageMongoImpl

when I do a dump of the jar file using jar tvf I get the following output

Remove runtime "content:content-examiner-data:1.0" or the jar file - you only need one. If you add jar files to the lib directory, you need to run grails compile --refresh-dependencies to get it added to the classpath
