[Openuss-developers] AW: [jonas] Error in JOnAS

Lofi,

I cannot tell you what you have to do, but I can tell you what we did.
=20
- Since EJB 2.1 has some great features, we moved to CMP 2.x years ago. =
Most features are running well, but some are buggy: e. g. Persistent =
Timers are only preliminary code, You cannot create related objects =
inside of ejbCreate, also some EJBQL things not working well, JOnAS =
mixes up datasources and so on... So you will get a lot of features, but =
also some ugly bugs.
=20
- We told our customers that there will be a solution to the readonly =
problem soon. So actually now all our beta customers are waiting to get =
their systems back running, and all our 'normal' customers just waiting =
for the final release, which we have cancelled for unknown time. We =
expect a solution before december, but it's up to JOnAS team if this =
will happen finally.
=20
So you need to decide on your own. Moving to EJB 2.1 is some work, =
indeed, but brings nice features plus some bugs you need to work around. =
Keeping with EJB 1.x is no work, but you need to restart every few =
hours.
=20
My tip would be: Try JOnAS 4.6. Maybe it works, even with EJB 1.x.

<Philippe>
In the case you woulkd use the new lock-policy CRW, available only in
4.6, the restriction are:
- the shared flag must be set to false.
- the entity bean must be CMP 2.x
</Philippe>

reading the answer of Philippe above, it seems we cannot use this
lock-policy CRW in EB CMP 1.x... :-( Hmm... so my options now are:
- Changing all EBs CMP 1.x into 2.x which will be a *huge* rework
   we cannot afford.
- Restart every 2-3 hours which will "kill" openuss from the user's
   perspective.
- Reinstall openuss 1.4 with JOnAS 3.x which did not have this problem.

Very difficult situation... Any ideas?

Thanks a lot!
