[news.eclipse.technology] Re: Error in eclipse Ant Build using ibator

["shao" <fafy_99@xxxxxxxxx>]

Thanks Wayne.
You are right that the source of error is outside Eclipse. I tried the same 
thing in command line, and I still got the same error. I'll try to get some 
help from the ibatis project.
THanks,
SHao
