Re: [castor-dev] jdo.getDatabaseName() call?

[Werner Guttmann]

Emir,

as stated in the API docs for JDO.java at

http://castor.exolab.org/api/org/exolab/castor/jdo/JDO.html

when instantiating Castor JDO, you have to provide a valid database name, either via the constructor as per

http://castor.exolab.org/api/org/exolab/castor/jdo/JDO.html#JDO(java.lang.String)

or via

http://castor.exolab.org/api/org/exolab/castor/jdo/JDO.html#setDatabaseName(java.lang.String)

Iow, setting a database name is required before you can make use of Castor.

Note: Please make sure that the name used is identical with the name used your config file, e.g. using a config file similar to

<database name="mydb" engine="oracle">
<jndi name="java:comp/env/jdbc/mydb" />
<mapping href="" />
</database>

should result into a call to either

JDO jdo = new JDO ("mydb");

or

JDO jdo = new JDO();
...
jdo.setDatabaseName("mydb");

I hope this helps.
Werner

Hi all,
can someone please explain me or point me to the API documentation regarding the call to getDatabaseName() before setting it with setDatabaseName().
I'm a beginner with Castor and just wondering why can't the database name be read from the database XML config file?
It appears as attribute in <database> tag, isn't it?
Or those names doesn't refer to the same thing?

I've tried to create JDO object, loadConfiguration() from XML file and then call getDatabaseName() to retrieve the database name. I got an excpetion saying that I need to setDatabaseName() prior to calling getDatabaseName(). That seems obvious, but I think that the load of configuration would retrieve and set the database name.

Thank you,
ec
