AspectJ - Cannot register non aspect error

I am trying to play with AspectJ and run time weaving.
I have created an aspect

@Aspect(value = "TraceAspect")
public class TraceAspect {
@Around("execution(* *(..))")
public Object around(ProceedingJoinPoint invocation) throws Throwable{

System.out.println(String.format("Invocing %s", invocation.getSignature().getName()));
try {
Object ret = invocation.proceed();
System.out.println(String.format("Done Invocing %s", invocation.getSignature().getName()));
return ret;
} catch (Throwable throwable) {
throw throwable;



and my aop.xml file is

<aspect name="TraceAscpect"></aspect>
<weaver options="-debug -showWeaveInfo"/>

however when I run the program I get exception -

java.lang.RuntimeException: Cannot register non aspect: TraceAscpect , TraceAscpect

What did I forget to add?

Looks like you have spelt the name of your aspect wrong in your XML definition, it should be TraceAspect and you've put TraceAscpect.
