Hi All,
I ran pojo cache, but hit error, following is the code and errors
| package org.jboss.cache.data;
|

I put thoes pojos into JBossCache-1.4.0.GA\tools\src and ran the ant all to generated the aopc classes(Persion.class,Persion$*.class,Address.class,Address$*.class,))
Then I tested POJOCache base on those class file, but hit error
