Weblogic can't lookup JDBC datasources internally.

[teddyj]

Hi,

Have a problem with JDBC datasources on a weblogic 9.2 single node
domain.
All datasources seem to be deployed correctly, test from console okay
and can be retrieved and used by a remote client using JNDI.
However on deploying an application to the domain we get a failure due
to javax.naming.NameNotFoundException. On checking the JNDI tree the
datasources are listed in black type (not blue as normal) with a red !
sign next to them.
It seems like the server is exposing datasources via JNDI correctly to
external sources but cannot retrieve them internally.
Has anyone come across this problem before? Or has any advice?

Thanks in advance.
