this code wrote testing only.this code working without eclipse fine , 1 more things when run project in eclipse giving exception of hsqldb not mysql can view full stack trance here. http://www.docdroid.net/2xuj/errro.txt.html

if configure datasource in tomee.xml , eclipse have steps also.

     locate tomee server configuration in workspace / servers(eclipse)      right-click server project , select import      select general - file system , click next      browse <tomee>/conf folder      select following files import: logging.properties, system.properties ,            tomee.xml       click finish import files.        in servers tab, right-click tomee server , select publish publish files eclipse metadata folder

this work.
