I m using Spring AOP architecture for Logging and Transaction management.we are using WSO2-ESB container
for deploying our service. Here the XML file which we try to read usingClassPathXmlApplicationContext().

</beans>

Actual problem occurred when i start my WSO2-ESB server. Here i have attached Stacktrace :

I would say that there is no spring-aop.jar (or wrong version) on the classpath. Or it isn't readable. – M.

spring-aop-3.2.5.RELEASE.jar is in the classpath and have the correct version. If you have any reference
or samples of Spring AOP implementation in WSO2-ESB then please share it. – Tejas

When is it on the classpath, during building or during deployment? – M.

we have used Maven for dependency management, so at build time osgi bundle resolve dependency from maven repository.But while deployment time, WSO2 ESB container provide
the required jar files so it resolve dependency from there. I m using the same version at both side. – Tejas

This problem occurred due to it can't find the path/location of spring-aop-3.0.xsd fromspring.framework_3.1.0.wso2v1.jar,
which is provided by the WSO2-ESB.

It can be resolved by two ways :

1) You can add your latest version of spring and set the priority of that jar files.
Reference

2) You have to just simply follow the steps described below. You have to add some files into META-INF folder of spring.framework_3.1.0.wso2v1.jar file.

Steps are shown below.

i) Create a new file spring.schemas and add the content shown below.

http\://www.springframework.org/schema/aop/spring-aop-2.0.xsd=org/springframework/aop/config/spring-aop-2.0.xsd
http\://www.springframework.org/schema/aop/spring-aop-2.5.xsd=org/springframework/aop/config/spring-aop-2.5.xsd
http\://www.springframework.org/schema/aop/spring-aop-3.0.xsd=org/springframework/aop/config/spring-aop-3.0.xsd
http\://www.springframework.org/schema/aop/spring-aop-3.1.xsd=org/springframework/aop/config/spring-aop-3.1.xsd
http\://www.springframework.org/schema/aop/spring-aop-3.2.xsd=org/springframework/aop/config/spring-aop-3.2.xsd
http\://www.springframework.org/schema/aop/spring-aop.xsd=org/springframework/aop/config/spring-aop-3.2.xsd

ii) Create a new file spring.handlers and add the content shown below.

http\://www.springframework.org/schema/aop=org.springframework.aop.config.AopNamespaceHandler

iii) Create a new file spring.tooling and add the content shown below.

# Tooling related information for the aop namespace
http\://www.springframework.org/schema/aop@name=aop Namespace
http\://www.springframework.org/schema/aop@prefix=aop
http\://www.springframework.org/schema/aop@icon=org/springframework/aop/config/spring-aop.gif
