Informix JDBC logging fails at WLS startup - repost, 1st one incomplete

Question

Hi,
I am trying to find out how to see how many db queries I'm doing
for a CMP finder. I am using the Informix driver I downloaded
from BEA. When I start up WebLogic, I get the following in the
jdbc.log file:
DriverManager.initialize: jdbc.drivers = null
JDBC DriverManager initialized
registerDriver:
driver className=weblogic.jdbc.informix4.Driver,weblogic.jdbc.informix4.Driver@20e990]
SQLException: SQLState() vendor code(-255)
weblogic.jdbcbase.informix4.InformixException: Informix error: -255 minor code=[0]
[ at processUpdate <Error> ] See Informix error codes for explanation
The Informix error manual says -255 means this was not in a
transaction. It seems to imply that WLS, in trying to start
logging, was ending a transaction.
The rest of the stacktrace shows:
at weblogic.jdbcbase.informix4.Statement.processError Statement.java:1579)
     at weblogic.jdbcbase.informix4.Statement.processUpdate(Statement.java:1344)
     at weblogic.jdbcbase.informix4.Statement.getMoreResults(Statement.java:1100)
     at weblogic.jdbcbase.informix4.Statement.execute(Statement.java:243)
     at weblogic.jdbcbase.informix4.Connection.findDBType(Connection.java:173)
     at weblogic.jdbc.informix4.Driver.newConnection(Driver.java:45)
     at weblogic.jdbcbase.informix4.BaseDriver.connect(BaseDriver.java:96)
     at
and the rest of the trace shows it trying to make a connection.
I don't know why this is happening. Any help would be greatly
appreciated.
TIA,
Matt

Joe,
Thanks for the info. I downloaded the Informix driver, installed
it, and configured WebLogic to use it, and it worked fine.
Informix has its own way of turning debug on, but once I read
their driver doc, it was fairly easy.cool. glad to help.

Hi Matt. The stacktrace shows that the problem is coming during
the driver's attempt to make a new connection. I don't know why
this is happening, but my standing advice for Informix connectivity
is for you to download and use Informix's own free type-4 driver.
It's better, faster and better supported than ours.
