Entity beans deployment - database data erased on following

[razel]

when I deploy an application containing entity beans and then deploy it again, all database data inserted is erased. What am I doing wrong?

Thanks

Look in ejb3.deployer/META-INF/persistence.properties and you'll see the default table creation strategy. On my 4.0.3 install it is:

hibernate.hbm2ddl.auto=create-drop

I don't seem to recall that always being the default, but in any event you'll find you want to override the table creation strategy by setting this property in your persistence.xml file.
