Hello Marco,
the format of the database.xml changed from previous versions to 0.9.6. For MySQL it now should look like:
<?xml version="1.0" ?>
<!DOCTYPE jdo-conf PUBLIC "-//EXOLAB/Castor JDO Configuration DTD Version 1.0//EN"
"http://castor.exolab.org/jdo-conf.xsd";>
<jdo-conf>
<database name="mysql" engine="mysql" >
<driver url="jdbc:mysql://localhost:3306/test" class-name="com.mysql.jdbc.Driver">
<param name="user" value="test" />
<param name="password" value="test" />
</driver>
<mapping href="jdo/mapping.xml" />
</database>
<transaction-demarcation mode="local" />
</jdo-conf>
Regards Ralf

Hello all,, I have just downloaded castor 0.9.5.6, and I am getting problems when instantiating castor JDO due to problems in reading databae.xml file
I can't figure out what should be the proper structure of database.xml file
The one that I have attached resembles the one that I was using with version 0.9.5.2...
The exception that I am getting is as follows
com.myapp.exceptions.PersistenceException: java.lang.Exception: Error in initial izing cpmgr!org.exolab.castor.mapping.MappingException: Nested error: unable to find FieldDescriptor for 'driver' in ClassDescriptor of jdo-conf{file: file:C:/S w/Budget-Project/Backend/target/test-classes/database.xml; line: 3; column: 87} 2004-11-14 11:42:23,328 ERROR com.myapp.castor.CastorPersistenceManagerTest [ma in] - Exception in testQueryExpenseType java.lang.NullPointerException
any help?
Thanks in advance and regards Marco
