auto-proxying and CFLIB error on application initialization

[garrett0168]

I am trying to setup @AspectJ autoproxying in Spring through the

<aop:aspectj-autoproxy/>

tag. However, when my application is initializing, I am getting spring configuration errors when initializing my normal POJO beans:

Initialization of bean failed; nested exception is: org.springframework.aop.framework.AopConfigException: Cannot proxy target class because CGLIB2 is not available. Add CGLIB to the class path or specify proxy interfaces.

	at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:512)

If I remove

<aop:aspectj-autoproxy/>

my application initializes without problems. I do not want to use CGLIB, so is there a way to avoid the CGLIB dependency? Any help would be appreciated.

Thanks.

As the message indicates, you don't have CGLIB jars in your classpath. Add those and the problem should go away.

Hi Ramnivas - Thanks for your reply. I know adding the jar to my classpath will fix the problem, but I don't want the dependency on CGLIB. Is there no other way to avoid using CGLIB?

[ramnivas]

You probably have a target class that doesn't implement an interface. Here Spring needs to use CGLIB to dynamically create a subclass. If you can manage to put an interface to such a class, you can avoid CGLIB dependency.
