Ejb3 + Hypersonic

[despontao]

Dear all,
when I do some modifications on my ejb3 classes, every time I deploy the new version I completely lost all my data in Hypersonic, although I don't clean anything.
At the moment, my ejb3 classes auto-generate the db schema.

What is my error? How can I solve this situation?

What is the setting for the hibernate.hbm2ddl.auto property in your persistence.xml file?

Hi Peter,
here below my persistence file :

<?xml version="1.0" encoding="UTF-8"?>
<persistence>
 <persistence-unit name="duckbrain">
 <jta-data-source>java:/DefaultDS</jta-data-source>
 <properties>
 <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
 </properties>
 </persistence-unit>
</persistence>

Hi,

I think you can give this a try

<property name="hibernate.hbm2ddl.auto" value="create-drop"/>

Change it to

<property name="hibernate.hbm2ddl.auto" value="create"/>

OR

<property name="hibernate.hbm2ddl.auto" value="update"/>
