Subject Re: connecting Hbase using java
Date Wed, 03 Apr 2013 16:59:02 GMT
I don't have my laptop with me at the momemt and honestly last time I 
ran a javac from command line it was about ten years ago but my 
questions is : are you sure you can use wildcard this way?
If I remember well, prior to JDK 1.6 you could not use widlcards at all, 
and starting from 1.6 you can use *only* wildcard, without the ".jar" suffix

Best,
Andrea
