24 Chapter 3. JOnAS Configuration
You can configure JOnAS to use several protocols simultaneously. To do this, just specify a comma-
separated list of protocols in the
carol.protocols
property of the
carol.properties
file. For
example:
# jonas rmi activation (choose from jrmp, iiop, and cmi)
carol.protocols=jrmp,iiop
3.3.2. Security and Transaction Context Propagation
JOnAS implements EJB security and transactions by using the communication layer to propagate
the security and transaction contexts across method calls. By default, the communication proto-
col is configured for context propagation. However, this configuration can be changed by disabling
the context propagation for security and/or transaction; this is done primarily to increase perfor-
mance. The context propagation can be configured in the
jonas.properties
file by setting the
jonas.security.propagation
and
jonas.transaction.propagation
properties to
true
or
false
:
# Enable the Security context propagation
jonas.security.propagation
true
# Enable the Transaction context propagation
jonas.transaction.propagation
true
3.3.3. Multi-protocol Deployment (GenIC)
The JOnAS deployment tool (GenIC) must be told which protocol stubs (for remote invocation) are to
be generated. Choosing several protocols will eliminate the need to redeploy the EJBs when switching
from one protocol to another. The default is that GenIC generates stubs for
rmi/jrmp
. To change this
configuration, call GenIC as described in Section 6.5 GenIC . Use the
-protocols
option to specify
a comma-separated list of protocols (chosen from
jrmp
,
iiop
, and
cmi
). For example:
GenIC -protocols jrmp,iiop
This list of protocols can also be specified for Ant EJB tasks (refer to Chapter 27 Ant EJB Tasks:
Using EJB-JAR ):
jonas destdir="${dist.ejbjars.dir}"
jonasroot="${jonas.root}"
protocols="jrmp,iiop"
keepgenerated="true"
verbose="${verbose}"
mappernames="${mapper.names}"
additionalargs="${genicargs}"
/jonas
3.4. Configuring Logging System (monolog)
The logging system is based on Monolog, the standard API for ObjectWeb projects (refer to
http://www.objectweb.org/monolog/doc/index.html). Configuring trace messages inside Jonas can be
done in two ways:
