Hi, all

I am following the book and its exercises. I used Mysql as the database. Everything looks fine, till I reached the "ex05_3". Though at last, it works fine, but I noticed something weird:

when I issued:

ant run.client_53

it silently said "build success" without the output supposed to be in the screen.

I did this "twice".

Then when I did this "3rd" time, I got the output!! And it seems that execpt the first 2 times, I will get the results.

Why is that? Anyone has any idea?

P.S. The extra descriptor file for MySQl data sourse and of course the titan-ds.xml:
