class not found SimpleAclEntry

I get this error when running my app under tomcat 5.x

ERROR web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationExce ption: Error creating bean with name 'net.sf.acegisecurity.acl.basic.SimpleAclEntry.ADM INISTRATION' defined in ServletContext resource [/WEB-INF/classes/applicationContext-common-authorization.xml]: Initialization of bean failed; nested exception is java.lang.ClassNotFoundException:
net/sf/acegisecurity/acl/basic/SimpleAclEntry
java.lang.ClassNotFoundException:
net/sf/acegisecurity/acl/basic/SimpleAclEntry


I have attached the xml declaration:
<bean id="net.sf.acegisecurity.acl.basic.SimpleAclEntry. ADMINISTRATION"
class="org.springframework.beans.factory.config.Fi eldRetrievingFactoryBean">
<property name="staticField">
<value>
net.sf.acegisecurity.acl.basic.SimpleAclEntry.ADMI NISTRATION</value>
</property>
</bean>


Any ideas?

Thanks,

Craig

I guess I should say I am using 0.8. I have checked my web-inf/lib/acegi.... jar file, and that class does exist.

thanks

I had authentication working fine before I introduced the authorization beans.

was a crlf or something in my xml file.
