Re: [JBoss-user] Keeping cmp beans in synch
Do you remove it by calling the database or the remove() of the entity bean? if the former... look at your default standardjboss.xml and change the commit option from the default of A. This presumes that the ejb has exclusive access to the database. you want either B (caching but non exclusive access) or C (non caching state loaded at the beginning of each transaction) al - Original Message - From: Chris Tragas [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, June 28, 2001 1:06 AM Subject: [JBoss-user] Keeping cmp beans in synch Hi. This might be a silly question but i'll ask anyhow: How do i keep my entity beans in synch (so to speak) if the data the bean is mapped to is updated in the datasource by another application or process ? what i'm experiencing is this: I use entity beans to cerate records in a dabatabse; my bean creates a record with pk_id = 1; then i remove the record from the database and initialise my sequence class back to 1 so when i call my bean.create i expect it to create a record with pk_id 1 again; but when i do this i get all sorts of ejbexcpetions errors; this leads me to believe that i'm upsetting the caching of jboss; can anyone point me in the right direction as far as what i am doing wrong; thanks.
