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

Hi all,
today I start afresh a Example code on
http://blog.rajeevsharma.in/2009/06/using-hbase-in-java-0193.html
but I guess luck is not with me.
I run
javac -classpath
~/packages/hbase-0.94.6/hbase-0.94.6.jar:~/packages/hbase-0.94.6/lib/*:~/packages/hadoop-1.1.2/*.jar:~/packages/hadoop-1.1.2/lib/*.jar
HBaseExample.java -verbose
please tell me what else I need to add in path to resolve these errors
thank you
