Does anyone uses Firebird and KODO (the JDO implementation from
SolarMetric)?

We are trying to use Firebird 1.5 (WI-V1.5.0.4290) and KODO 3.0.3.
But unfortunately the mapping tool exits with:

kodo.util.FatalException: com.solarmetric.jdbc.ReportingSQLException:
GDS Exception. 335544351. unsuccessful metadata update
Column: ID not defined as NOT NULL - cannot be used in PRIMARY KEY
constraint definition {stmnt 24446859: CREATE TABLE
md_global_field_contents (CONTENT VARCHAR(255), ID INTEGER, JDOCLASS
VARCHAR(255), JDOVERSION INTEGER, PRIMARY KEY (ID))} [code=335544351,
state=HY000]

Does anyone knows help?

Holger
