Hi,
I'm getting the exception at the bottom of the mail.
Could the error
"com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException:
Connection.close() has already been called. Invalid operation in this
state." be a consequence of using dhcp connection pooling?
My persistence.xml properties file looks like this:
<properties>
<property name="openjpa.jdbc.SynchronizeMappings"
value="buildSchema"/>
<property name="openjpa.ConnectionDriverName"
value="org.apache.commons.dbcp.BasicDataSource"/>
<property name="openjpa.ConnectionProperties"
value="DriverClassName=com.mysql.jdbc.Driver,Url=jdbc:mysql://localhost:3306/sitedelta,Username=sitedelta,Password=sitedelta"/>
<property name="openjpa.DataCache" value="true"/>
<property name="openjpa.DataCacheTimeout" value="3000"/>
<property name="openjpa.RemoteCommitProvider"
value="sjvm"/>
</properties>
If this were an issue with dhcp does anyone have an example
persistence.xml using c3p0?
Thanks
Joel
