Ebean and JavaFx

[Masimo]

Hi all,

I have some severe problems to get ebean up and running in a JavaFx
desktop application. Environment is:

NetBeans: 6.9.1
JavaFX: 1.3.1
Ebean: 2.6.1
Java: 1.6.0_17


When I start the application from IDE or from command line, I get the
following stack trace:

When I use the -javaagent option to enhance the POJOs at runtime, it
shows me the enhancements on the console. However, I get still the
message: javax.persistence.PersistenceException:
cyberclient.model.Customer is NOT an Entity Bean registered with this
server.

BTW: When I use a unit test from IntelliJ IDEA everything works fine.
(I can't use IntelliJ IDEA with JavaFX 1.3.1, that was the reason to
switch to netbeans. However I believe, this has something to do with
JavaFX and not with the IDE )

Any ideas are very much appreciated.

Regards
Martin

This error indicates Ebean could not find any Entity Bean classes in the classpath.

I'd guess and say that your entity beans are in a JAR file.

That is, Ebean by default doesn't search inside the jars. You need to tell Ebean which jars it should look in for the entity beans.

You can do this by specifying the jars to search (comma delimited):

ebean.search.jars=CyberClient.jar,SomeOther.jar



Cheers, Rob.

Hi Rob,

perfect guess! Now everything works fine.

Is the ebean.search.jars required independently from the "type of
enhancement" (ant/javaagent/automatic subclassing)?

Thanks a lot

>> perfect guess! Now everything works fine.

Cool. Unfortunately a few people have hit this so really it should be documented a bit better. Perhaps a better description in warning logged when no entity beans are found via classpath search.

Yes.
