I'm trying to follow the POJOCache tutorial and have been running into problems. The first problem is that the GUI won't start up most of the time. I get the message "[java] start(): creating the GUI" but then nothing else happens. It took me five tries before I could get the second GUI to pop up for the tutorial the last time I tried. Also, I'm entering the commands shown in section 7.1 of the tutorial and I run into problems again. The commands in step one usually are fine, but the command to attach the joe Person object always gets me the following error: | | // Error: // Uncaught Exception: Method Invocation cache.attach : at Line: 1 : in file: <unknown file> : cache .attach ( "pojo/joe" , joe ) | | Target exception: java.lang.IllegalArgumentException: PojoCache.putObject(): Object type is neither aspectized nor Serializable nor an array of primitives.

All I have is the class file for the object so I can't even look inside to see what's there. Is anyone else having these problems? Any suggestions on how to get the tutorial working properly?
