Hi Ashish,
The first thing I will check is your classpath.
Looks like you are trying to run "java hellojpa.Main " but this is already
part of "ant" that you run and the output from ant command
"run:
[java] 4782 hellojpa TRACE [main] openjpa.jdbc.SQL - <t 16322634,
conn 2
7041558> executing prepstmnt 26426059 INSERT INTO Message (id, created,
message)
....
"
is part of running hellojpa.Main from with in ant.
Regards,
Ravi.
