[JBoss-user] easy to implement Informix Support ???

[Schneider, Joerg (Zentrale Frankfurt)]

Hello everybody,

after reading all the messages in this mailing-list regarding support of
Informix databases, i've the impression, that supporting this database
should be easy and could be done with small efforts.

First of all, i want to state what is working (in my opinion) by now (jboss
2.1) :

        Establishing connections, if the minerva-class XADataSourceImpl is
used.
        Database operations, if transaction and persistent type is bean

Second, here's what is not working (in my opinion) by now (jboss 2.1) :

        If the IfxXADataSource class is used, an exception is thrown while
starting jboss with message "wrong argument" (please review older messages
in this mailing-list describing the exact stack-trace).  
        If transactions should be handled by the container, an
runtime-exception is thrown with message "xares not enlisted".

In my opinion, the informix-jdbc driver 2.20JC1 (type 4, XA implemented)
works fine, except it is missing the methods "setURL" and "setProperties",
which are used by jboss to configure the XADataResource. 
According to previously sent mail's, the way to configure a XADataSource is
not part of any specifications, so any vendor can implement whatever methods
he wants to do configuration. The informix jdbc-driver offers a lot of
methods to use for config issues (setUser, setPassword, setProperties,
setDatabase) and is well documented to.
 
So, a slight change of the jboss config-procedure could make this database
easily available :-).  

For developing and testing purposes, one can obtain all informix-products
for all platforms from "www.informix.com/evaluate/ after registering
free-of-charge for a limited period of time.

If anyone has successfully configured an informix database-environment
(which means, i'm wrong with all my conclusions) with jboss 2.1, please let
me know. 
Otherwise, i would suggest to enhance jboss the way i mentioned above (this
is far more easy for a active member of the development community, as it is
for me, isn't it ?).

Kind regards

Joerg Schneider
