I would say that there is no spring-aop.jar (or wrong version) on the classpath. Or it isn't readable. –  M. Deinum  Jan 20 '14 at 9:39 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 Patel  Jan 20 '14 at 10:31 When is it on the classpath, during building or during deployment? –  M. Deinum  Jan 20 '14 at 11:13 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 Patel  Jan 20 '14 at 11:55 add a comment

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 share improve this answer edited Jan 21 '14 at 7:13 answered  Jan 21 '14 at 6:35 Tejas Patel 39 1 11
