INFORMIX 9 and SUN Studio Enterprise Configuration

Question

Attention all informix to java programmers
Architecture regulations obliges the use of the J2EE platform. Sun ONE
Application server 7 is the appserver to use and Informix Dynamic Server
9.22 the database. This is not the most mainstream combination.
Especially since Sun ONE doesn't support the Informix database.
It turned out that you can use this combination, but you need to apply
some workarounds.
First you need to know which properties to set for the datasource. This
is the list:
IfxIFXHOST=foo.bar.com
PortNumber=1527
User=Krusty
Password=L3k4N1%j
ServerName=foobarifx_ol
DatabaseName=testdb
The values are examples. Be careful of the syntax. The first letter
should be a capital!
The second adjustment is a little harder. Because Informix syntax isn't
fully ANSI92 compliant (it doesn't support right joins),
the persistence manager of Sun ONE generates illegal SQL when
fulfilling it's CMP responsabilities.
To solve this problem you need to add a property file to the
appserv-cmp.jar.
This lib is part of the Sun ONE server libraries and you can find it at
{Sun ONE INSTALLDIR}/lib.
The file name should be "INFORMIX DYNAMIC SERVER.properties" and it
should go under the folder
com/sun/jdo/spi/persistence/support/sqlstore/database.
This is the content of the file:
FOR_UPDATE=for update
LEFT_JOIN=LEFT OUTER JOIN
RIGHT_JOIN=,
RIGHT_JOIN_PRE=outer
IS_NULL=IS NULL
IS_NOT_NULL=IS NOT NULL
RTRIM=trim (trailing \" \" from
RTRIM_POST=)
QUOTE_CHAR_START=
QUOTE_CHAR_END=
Having this information up front would have saved me many hours of frustration. I hope anyone else using Informix 9 and J2EE finds this helpful.

i follow this steps , but i still have problems now i got this exception
[19/Jul/2005:20:17:53] INFO ( 3812): CORE3282: stdout: java.sql.SQLException: com.informix.asf.IfxASFException: Attempt to connect to database server (srvr_cannes_tcp) failed.
i think is the ServerName variable did you know which is the problem; i'm still frustrated
