Anybody else have this problem?/Feature Idea

There are some aspects of OJB that require/encourage having two pieces of data to represent single relationship. 1) When I have an referenceDescriptor, I have to have a fooOid, and a Foo, both of which are two ways of referring to the same thing. 2) When I have a collectionDescriptor, I have a

Re: Why is OJB inserting null on one field?

The issue isn't the presence of the record in the table. It's the presence on the newImport of an Lu_process_status object which represents the Q record in the database. When you store newImport, ojb looks at the content of newImport to figure out what values to use in the sql statement. In

Re: Anybody else have this problem?/Feature Idea

Hi David, Application code should (never?) touch the fooOid, only the referred Foo objects should be manipulated. Likewise for the collections and their parent object id. OJB does the underlying synchronization for you. But maybe you have some special conditions that sometime require you to

RE: Why is OJB inserting null on one field?

Another helpful thing to know is that PersistenceBroker.retrieveReferences(myObject) will automatically update any reference objects attached to myObject from the corresponding foreign key ID fields. -Original Message- From: C F [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 04, 2003

RE: Ternary associations

Hi Charles, Thanks for the detailed answer. That does the job nicely. We had moved from an m:n relationship and were somewhat blinded by the fact that we hadn't been using the association table directly (we had used it as an 'indirection-table'). Thanks again, John -Original Message-

I absolutely agree with Charles! the automatic handling of foreign keys was build to let developers concentrate on business objects and not on rdbms details. Thomas Charles Anthony wrote: Hi, Developer should only ever set foo, and should never set fooId. OJB manages all foreign keys. In

Re: automatically mapping inherited fields

Hi Joerg, I'm not quite sure if I got your question. Are you asking if the field-descriptors for name and number must be present in the class-descriptors for the concrete classes, or if it is possible to just define them once in the base-classes descriptor? The answer to this question is:

Hi David, The testsuite has been tested against HSQLDB only. So it's quite possible that certain special thing fail for certain other platforms. This is normally nothing to worry about. Not all RDBMS/JDBC drivers support all possible features. Just have a look at the log files in target/test

Phillipe, I keep my repository*.xml files in WEB-INF/src, and eclipse seems to copy them over to WEB-INF/classes for me. I also use the Sysdeo Tomcat plugin, which may be what's actually helping me out. HTH, Colin [EMAIL PROTECTED] wrote: Hello, I am currently building a web application

Hi all, One other thing to maybe mention about Charles' example is that the PROJECTRELATIONSHIP table has a composite primary key consisting of DEVELOPER_ID, LANGUAGE_ID and PROJECT_ID. I didn't see this in the repository extract. Phil Thomas Mahler wrote: Hi Charles, thanks for the good

RE: Anybody else have this problem?/Feature Idea

Hi Thomas, This may be a bit off topic I use OJB exclusively in a web application environment. When a web form posts to one of my actions I only pass the ids of any dependent objects (from a list box etc...). I would like to set this id on my target object and then store it. Of course,

Date criteria

I'm trying to do something like: select * from contributions where last_activity = '2003-03-04 14:35:38'; but using this: criteria.addGreaterOrEqualThanField(lastActivity, date); or criteria.addGreaterOrEqualThanField(lastActivity, formatter.format(date)); doesn't work. Any ideas? --Scott

Hi Adam It's a compiletime depency. So if your application does not use any J2EE features there's no problem at runtime without that jar file. cheers, Thomas Adam Griffiths wrote: I only wish to map a the objects of a standalone application to a local database. Is j2ee still required for me? I
