i did not solve the problem, but is did not occur during the last days.
What does it mean: the resources setup? Do u mean the JDBC connection pool
setup? I use this connection pool since almost two months now without
changes,
but sometimes i get this error. Moreover, and this is happening much more
often,
the deployment fails because Eclipselink can not re-create the database
tables
when i set "drop-and-create-tables" to true. the existing tables can not be
dropped and creating the new tables fails. Then i re-deploy the application
once again it works most of the time. sometimes i need to restart glassfish
to be able to successful deploy the web app.
