Thanks for the observation! However, looking at the 2.0 specification, only chapter numbering has changed. The relevant texts seem to be identical.
WebLogic 6.1 does not claim to be compliant with EJB 2.1 (this would be temporally impossible I believe). If you look at the EJB 2.0 spec, this section is different (it is 10.5.9). See if that makes more sense. >From: johan <[EMAIL PROTECTED]> >Reply-To: johan <[EMAIL PROTECTED]> >To: [EMAIL PROTECTED] >Subject: Re: CMP and writing instance back to database >Date: Sat, 17 Apr 2004 15:15:15 +0200 > >Why would you assume that "synchronizes the instance's state with the >persistent storage" should require the container to force beans to >persistent store even though the container knows the state is already >in sync (because it was never altered)? > >/johan > >On 2004-04-17, at 10.20, Janne Mattila wrote: > >>Some confusion about the EJB specification: >> >>EJB 2.1 specification, 10.5.10, "commit options" states that "container >>synchronizes the instance's state with the persistent storage at >>transaction commit for all three (commit) options".
