Could not passivate; nested except

[sundaram]

Hi,

I am getting the following error, I have only one CMP entity bean with oracle DB and one session bean.

In my session bean I am using the following logging.

private final Category log = Category.getInstance(getClass().getName());
..
..
log.info(...)

Any Idea, Why I am getting this error.

try private transient Category log = Category.getInstance(getClass().getName());

but you've to manually reinit this field in activate().
Or maybe you could set it private static final transient?
