We use identity generation with GenerationTyp.AUTO to support different DBMS (mssql and postgre) with a sequence generator for each Entity:
{code:java}
@SequenceGenerator(name = "SEQ_MY_CLASS", sequenceName = "SEQ_MY_CLASS")
public class MyClass {
private Integer id;
....
@Id
@GeneratedValue(strategy = GenerationType.AUTO, generator = "SEQ_MY_CLASS")
public Integer getId(){
...
}
}
{code}
persistence.xml
{code:xml}
...
<property name="hibernate.hbm2ddl.auto" value="update" />
<property name="hibernate.default_schema" value="myschema />
<property name="hibernate.id.new_generator_mappings" value="true"/>
...
{code}
If I start wildfly and it tries to create tables, sequences, etc. mssql, I get the exception at the bottom.
A possible workaround ist to define the catalog in persistence.xml with
{code:xml}
...
<property name="hibernate.default_catalog" value="mycatalog" />
...
{code}
But if I do this I run into another bug, I described in HHH- 10819
This issue is already discussed in hibernate forum:
Exception on wildfly startup:
