Hi Aristedes!
I submitted the issue here:
https://issues.apache.org/jira/browse/CAY-1216
Let me know if this works for you.
Regards,
Peter.
Hi,
I am in the process of trying a migration from hibernate to cayenne and
I read on the list that there is no tool provided for doing this
automatically, right?
Now I see that the modeler says that there are IDs missing in
relationship tables.
With relationship table I mean the table between a
Hi again,
finally I got the mavenized tutorial in the subversion working.
So, again step by step:
1. get the remote-object-persistence-tutorial from source and replace
the dependencies with the latest versions (I used cayenne 3.0M5 - see
the appended pom's).
2. update the autogenerated classes
Hi Daniel,
it seems to me that
CayenneDataObject.addToManyTarget(String targetName, DataObject obj,
boolean reverse);
and
CayenneDataObject.setToOneTarget(String targetName, DataObject obj,
boolean reverse);
could do the job for you.
Am I right?
Peter.

I am seeking for a solution where the following works:

Hallo,
thank you again: now I got it!
I needed examples :-)

false);
I have to think about it again,

Hello!
I profile my application with netbeans profiler.
And I figured out that there are 12 (!) EventManager's DispatchThreads
started.
All are in the 'waiting' state.
I have no problems with that :-)
But could it be that this code is problematic:
public static EventManager getDefaultManager() {

My unit test passes, after the "Object getID()" change.
Thank you for that hint.
I'll be back tomorrow if I get other/further problems :-)
Peter.

Yes! I was trapped in my idea that a pk has to be integer :-(

I think the first line is always true, what about the second?
Then I can create a SimilarEntry which holds a TimeInterval and
"overloads" the equals method by comparing by the pointers (&q
for some calculation and not for persistence
Is there another approach?
Thank you,
Peter Karich.

Hallo!
I think xstream is very easy to use and it works fine for me.
E.g. use:
XStream xs = new XStream(new DomDriver());
//Xpp instead dom would be faster ...
OutputStream os;
try {
os = new FileOutputStream(xmlFile);
xs.toXML(obj, os);
} finally {
os.close();
}
For deep object d
dProperty(BIT_SET_PROPERTY));
ObjectInputStream o = new ObjectInputStream(bais);
BitSet date = (BitSet) o.readObject();
//is closing necessary: (?)
o.close();
Thank you again and sorry for this not-cayenne-related question,
Pet
rther documentation on that subject? Because I can't find
useful informations in javadocs and google results.
Does anyone has a simple example of reading+writing an arbitrary object?
Thank you,
Peter Karich.
