Hi everyone,
I encountered problem when i write a simple Jade persistence unit in Java using NetBeans IDE. I followed exactly from Java persistence white paper published by Jade, but when I excute (run) my application, it shows error message

Exception in thread "main" com.jadeworld.jade.AnnotationException: failure attempting to process annotations for class javaTest.Person from persistence.xml

I m pretty sure my directory is correct. I placed the persistence.xml directly under the source package directory and my javaTest was also directly under the source package directory. I also imported the javajom.jar into NetBeans libraries. I tried for 3days, but still very clueless where i went wrong. Does anyone knows why? Is there any special steps to take using NetBeans for persistence unit? Please advice. Thanks!

Just covering all bases, I take it the jadrap was up at the time you executed the java application?

hi swishy, jadrap is Jade Database server right? yup, i have that running in the background when i run my Java app. is it the right way?

Sure is, thanks for that, anything in the jommsg log to indicate an issue with the connecting java client?

Cheers
Dale.

Hi swishy, thanks for ur prompt reply, i do not know how to read the jommsg log, but this is the last entry that i had

Hi Ken,

I dont see any jade clients connecting while the Jade Database server is running, you can see the server shutdown at

2010/05/13 11:40:44.796 010e8-0b88 SCOPERATOR01: (jadrap) Finished: exit code 0

all logging post this shows jade clients in single user ( I take it this is from an IDE connection? or was this attempting java connection in singleUser ? )

Cheers
Dale.

Hi,

A couple of things:

1. Is the Person class annotated with @Entity tag?
2. Make sure the letter casing is correct through out your project for the package name javaTest

Also, the persistence.xml file should be located under your META-INF folder.

Cheers.

Hi Dale, Sorry for the late reply, was away from office for a while. I not very familiar with Jade, thanks for telling me that my server is shutdown. I have not decided on single user or server client connection, i am juz trying out to run java code using Jade. I think the code i wrote is trying to connect from an IDE. becoz i am using NetBean to compile while the Jade server is running.

Thanks
ken
