[JBoss jBPM] - Row lock contentions on BPEL_FROM
by meghanai_99
Hello,
We are using JBPM 3.2 and BPEL extension 1.1GA. It is using Oracle as backend and running quite a bit of load. We are seeing row lock contentions on BPEL_FROM table a lot. The one query we see multiple times is -
update BPEL_FROM set ELEMENT_=:1 where ID_=:2
After investigating further, we found that due to Hibernate's auto flushmode, BPEL_FROM table records are updated every time flush is called. However the data of these records never change in reality.
After adding the mutable="false" flag on From.hbm.xml file, these queries are not run anymore. However we would like to know if it is safe change to make. Was it by design that the rows get updated everytime or is it a bug and we should create JIRA issue for it?
Thank you,
Meghana

orm based auth problem
by haipeng du
I configure my web application with form based authentication. When I type
the url for protected page, jboss redirect to my login page. The problem is
that jboss renders my login page first and then invoke the request listener
and filter class. I have print out messages in my login page and listener
and filter classes and for sure messages were printed out first in login
page. If I just type login page url directly, messages were printed out
first in listener and filter classes. I try the same war file in jetty
server, it always has the right order: call listener, filter and then render
page. Do I need to change configuration to make it work or I need change my
code? I must call filter and listener first before rendering login Page. My
jboss server is 4.2.3.GA
