Sessions and W98 + IE
Hi Im having problems with "broken" sessions for w98 + IE browsers. Does anyone know of errors in the Orion sessiontracking mechanism? /David

Re: Sessions and W98 + IE
Hi David. The major errors I have come accross in IE (all tested version of 4, 5, 6) was that the 56bit encryption package was completely broken in IE. The workaround was to force 128bit, or no encryption. I am not aware of any other issues. -Steve David Tunkrans wrote: Hi Im having problems with broken sessions for w98 + IE browsers.

Any advanced CMP mapping for int[] via java.sql.Array to a VARRAY col type?
Can anyone point me in the direction of some more detailed information on advanced CMP mapping techniques? I was wondering if a CMP mapping can be found which would generate JDBC code to bind a field variable defined as an array of integer via a java.sql.Array type to a database column defined as a varray of number under Oracle? I have been experimenting a little in and around this area but am not finding much on this in the Orion documentation and am having difficulty applying what I can find to my needs. My searches on the mailing list archives also don't find anything on java.sql.Array or much relevant traffic on other terms such as 'persistence-type'. Is there an API which allows users to provide enhancements to the facilities provided by the current CMP implementation? If so am I missing some more detailed documentation or useful examples on this? Regards, Andy Parkman
RE: Any advanced CMP mapping for int[] via java.sql.Array to a VARRAY col type?
I think there's a PersistanceManager interface for this, but I remember it not being configurable from files, that is, it seems it's not fully implemented yet. I guess you'll have to resort to BMP for such complex mappings. My 2c, Juan Pablo Lorandi Chief Software Architect Code Foundry Ltd. [EMAIL PROTECTED] Barberstown, Straffan, Co. Kildare, Ireland.

Re: Sharing datasource
Yes, that is true. At the moment, there is no EJB clustering in Orion, although it may appear in future versions. Cheers, Scott Linus Larsen wrote: If the same EJB application is running on lets say two servers, and are sharing the same datasource. Do I have to configure the orion-ejb- jar.xml and set the exclusive-write-access=false for every entity deployment (on both servers) sharing the datasource, to avoid inconsistency in the EJBCaching? regards /linus -- Scott Farquhar :: [EMAIL PROTECTED] Atlassian :: http://www.atlassian.com Supporting YOUR J2EE World
Re: Sharing datasource
Erm, nope. Orion has EJB clustering, it's just not documented, although I hear a document about it is coming out soon...ish...

RE: Can I write JDBC Transactions in Bean managed entity Beans?
Yes, there is. Since you're not using transactions that are independent of the app server(and thus the app server doesn't know about the transaction at all, and isn't able to vote in it) the app server built in transactional support is not functional. An example: EJB A: a SLSB EJB B: Your Entity Bean, PK=1. EJB C: Your Entity Bean, PK=2. If A, within a method, calls and modifies B and then C, and the calls on C produce an exception, B will be commited to the database. Where: EJB A: a SLSB EJB B: A correct Entity Bean, PK=1. EJB C: A correct Entity Bean, PK=2. If A, within a method, calls and modifies B and then C, and the calls on C produce an exception, the transaction will be rolled back. You should use either CMT or BMT in your BMP Entity Beans. Simply not coding transactions should do, the container would automatically handle the transactions (that's CMT).

Hai, According to spec we must use declarative transactions for entity beans. But I used JDBC transactions. It works fine.
