Hi Šabo,
I don't have a pure Cayenne answer, but in case you can add an extra field to
your table, then you can write a simple program to convert your IP addresses to
numbers and save the numbers to the newly added field. Here is a simple Java
method I am using to convert IPV4s to a long:

Hi,
What version of Cayenne are you trying? To check if everything's mapped
well, open cayenne.xml with Cayenne Modeler, find ObjEntity (green icon)
Artist and make sure that org.example.cayenne.persistent.Artist is specified
as class name. But, if you hadn't changed anything in tutorial project,
Hello,
I am new to using Cayenne so I decided to first start by going through the
tutorial. All went fine until I tried to build my project. I get an error
that says:
Exception in thread "main" java.lang.IllegalArgumentException: Class is not
mapped with Cayenne: org.example.cayenne.persistent
Andrus,
One more data point (based on another test):
I just change the "Delete Rule" associated with the three ObjEntities and then
tried to save the project. The dialog popped up:
Title: Synchrnize ObjEntity with DbEntity
CheckBox
value: checked
I've written a great deal of templates (generated entire CRUD web apps
straight from the model in struts and JSF) which I run from ant cgen,
but I can't make them available.
If you post specific questions, I can answer them.
Basically, you need to choose whether you want to generate one file

OK. Sorry, I think I misunderstood one of the prev

Hi Joe,
You need a foreign key in your database table.
You need a foreign key attribute in your DbEntity. You also need a
DbRelationship.
You do not need a foreign key attribute in your ObjEntity -- you only
need the (Obj)relationship.

Kevin,
I think we might have a communication problem. First of all let me say that I
will follow any instruction the team requests in order to solve this problem.
Cayenne is one of the best pieces of software I have ever used.
Also, I have my own methodology when analyzing a problem. The fir

Here is the info that your requested:

Hi Joe,
(Disclaimer: I also haven't looked at the code involved yet).
An OutOfMemoryError can be associated with many kinds of conditions.
You can have an infinite loop not causing an OutOfMemory. And also
OutOfMemoryError is by itself often causing a UI freeze, as the JVM
tries to free up
The behavior by an app in which it freezes for about 3-4 minutes and then
generates an out-of-memory-error is typically associated with an infinite loop.
Increasing the available memory to an app does nothing to analyze the problem.
It is more likely to be associated the the CM attempting to "r
Sure, but you can run the modeler with an increased heap size, like
java.exe -Xmx512m -jar CayenneModeler.jar
