Hi Ajharul Abedeen,

java.lang.NoClassDefFoundError: org/springframework/beans/factory/config/BeanExpressionResolver

java.lang.ClassNotFoundException: org.springframework.beans.factory.config.BeanExpressionResolver

The above Exception is clearly saying that BeanExpressionResolver is not available at Runtime.
If you are using Dynamic web project , Do check about spring-beans.jar file is added or not ?
If you are using Maven project Do check about spring-beans dependency is added to pom.xml file or not ?
for example

Consider Paul's rocket mass heater.
