newbie - lots of exeptions

Hi 

I'm very new to objectdb . I have bought a server and really want to use it. Our code works well with eclipselink and postgresql - until we stress it which is why I'm trying to get objected to work.

realy wierd things are going on ... we are using hessian to connect our remote clients to glass fish and invoke methods there (fine with postgresql) . here is our log (part of it at least .... exceptions are happening all the time when we're working with objected).

Can anybody help with this urgently please ?

Thank you

The exact cause is unclear, but the stack trace indicates that the exception is thrown when ObjectDB tries to scan classes in order to find entity classes and other annotations automatically.

Apparently, you can disable this process by specifying <exclude-unlisted-classes/> in the persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence  http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
  <persistence-unit name="ProhireNetwork_DataSync-ejbPU" transaction-type="JTA">
    <provider>com.objectdb.jpa.Provider</provider>
    <class>com.prohire.agent.entities.AVBooking</class>
    <class>com.prohire.agent.eantities.AVVehicle</class>
    <class>com.prohire.agent.entities.CompanyLocation</class>
    <class>com.prohire.agent.entities.CompanyPollStatus</class>
    <class>com.prohire.agent.entities.HireCompany</class>
    <class>com.prohire.global.vehiclemodels.VehicleModelDetails</class>
    <exclude-unlisted-classes/>
    <properties>
      <property name="javax.persistence.jdbc.url" value="objectdb://localhost/prohire_networka8.odb"/>
      <property name="javax.persistence.jdbc.user" value="admin"/>
      <property name="javax.persistence.jdbc.password" value="admin"/>
    </properties>
  </persistence-unit>

Please check if this makes any difference.

In addition to the suggested workaround above, a new build (2.4.4_16) includes an attempt to bypass these exceptions.

Hi

Thanks for the update ..

In the meantime we tried an earlier version ... 2.4.4.6 and the exception went away and our objects are persisted. We've just tried 16 and we get one exception (below) and the no other exceptions after. Our objects are now being persisted.

 

thanks for your help !

Paul

The last stack trace was produced by build 2.4.4_06:

This new exception is not related to the exception that was reported at the beginning of this thread. It may be the result of switching an ObjectDB version at the client side and keeping the server running. Try restarting the server with the new build and see if new exceptions are logged.

Hi Again,

We now have the an issue with log details below ...

We're trying 6 again to make sure we haven't broke again

Hi Works perfectly in version 6 Any ideas ? Thanks Paul

The stack trace in #9 may represent a partial enhancement or incomplete build. Please try rebuilding and enhancing all your classes. It may solve the problem with build 16. There is no known difference between build 6 and 16 that may cause this exception.

If this doesn't help - please provide more details. What can you tell about field CompanyLocation.locationPKey? Is it a primary key field? Are there recent schema changes in that class or class hierarchy? Are there additional stack trace lines in the log (the root cause is missing)?
