Is geronimo compatible with resource adapters deployed in weblogic

[Sai Arunachalam <sa...@gmail.com>]

Hi,
    I would be happy to know as to what would be the equivalents for
the following 4 tags that are part of weblogic-ra.xml  (weblogic
specific deployment descriptor for resource adapters).

weblogic has what is known as a principal map for security:

<security-principal-map> 
(provides a mechanism to define appropriate resource-principal values
for resuorce adapter and EIS authorization processing, based upon the
known WebLogic runtime initiating run time initiating-principal. This
map allows for hte specification of a defined set of initiaitng
principals and the corresponding resource principal's username and
password that should be used when allocating managed connections and
connection handles) This has subtags that are <map-entry>,
<initiating-principal> and <resource-principal>.

<map-config-property>
(identifies a configuration property name and value that corresponds
to an ra.xml config-entry element with the corresponding
config-property-name. At deployment time, all values present in a
map-config-property specification will be  set on the
ManagedConnectionFactory.

Weblogic has the following tags that are extra as the parameters for
connection pooling:

<capacity-increment> 
(identifies the max number of additional managed connections which the
server attempts to obtain during resizing of the maintained connection
pool)

<shrinking-enabled>
(indicates whether or not the connection pool should have unused
managed connection reclaimed as a means to control system resources)

two more related tags are <shrink-period-minutes> and
<connection-cleanup-frequency>

If anybody can tell me as to how I port a RA with a weblogic-ra.xml
that has the above tags, i.e. what tags should I add to geronimo to
get the same functionality, that'd be great....

Thanks in advance,
Sai

Geronimo defines what is known as a ReamlBridge. Various RealmBridge 
implementations are availale (have a look here 
org.apache.geronimo.security.bridge) and this WebLogic configuration 
refers to a PropertiesFilePrincipalMappingUserPasswordRealmBridge.

The tag to use is <realm-bridge>, cf. the .xsd. It specifies a 
RealmBridge name.

Then, you declare the RealmBridge which matches your needs at the end of 
the geronimo-ra.xml file. This is a standard GBean, yet its name MUST be 
geronimo.security:service=RealmBridge,name=<the RealmBridge name that 
you are declared>

This guy overrides the one in the ra.xml DD.

This tuning parameter is not implemented. The various pool 
implementations add only one ManagedConnection at a time.

As a matter of fact, I have never used this WebLogic feature. Having 
said that, Geronimo implements other features.

Not sure.

I've found that this isn't needed - geronimo will load the values from
the ra.xml config-property elements without needing an entry in
geronimo-ra.xml, at least for resource adapters so it should work for
connection factories, too.

I'm not sure, but I'd say that these look like tuning parameters to me
so you're probably OK for testing without them.

I think that the schema for the geronimo-config.ra file is
modules/connector/src/schema/geronimo-connector_1_5.xsd in the
geronimo source tree.
