Error Initializing TransactionProxyFactoryBean - Please Help

[jpwinans]

Hey All,

I'm having a problem plugging Hibernate into my application. I'm getting a java.lang.IllegalStateException error.

16:04:05,032 ERROR [ContextLoader] Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'casApplication' defined in resource [/WEB-INF/applicationContext.xml] of ServletContext: Initialization of bean failed; nested exception is org.aopalliance.aop.AspectException: null
java.lang.IllegalStateException: Callback Lnet/sf/cglib/proxy/MethodInterceptor; is not assignable to Lnet/sf/cglib/proxy/MethodInterceptor;

It throws this when it tries to initialize my ApplicationImpl bean. Here is my ApplicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http&#58;//www.springframework.org/dtd/spring-beans.dtd">
<beans>
<!-- ======================= APPLICATION CONFIGURATION ==================== -->

	<bean id="casApplication" parent="baseTxProxy">

	<bean name="casApplicationImpl" class="com.sccc.cas.domain.CasApplication">

	</bean>
	
	
</beans>

And here is my hibernate.xml configuration...

Does anyone know why I might be getting this error?

Thanks,

James,

If I remember correctly, I encountered this problem with an older version of CGLIB. Try upgrading to 2.0.2 or 2.1dev. Make sure that this is the only version of CGLIB on your classpath.

Thank you so much. That was what it was. I didn't even consider it because I have everything working in another application. This application looked identical, so I figured it was something else I was doing. Man I love these forums.

Thanks,
James
