Hi again,

The exact problem was that I was compiling my java files in JDK7 and on hosting server JDK1.6 was installed. I removed JDK7 from my computer and install JDK6 and then compiled all the files and placed again on server. I made the same changes in /conf/server.xml and restarted.

Its work fine now.

The issue fixed

Best regards
