Hello,
I am using a clsutered JBoss4.0.5 with EJB3 profile.
I have defined an Oracle10 datasource.
The datasource is defoned in the following file SDOCI-ds.xml:
<?xml version="1.0" encoding="UTF-8"?>

| <!-- $Id: oracle-ds.xml 23720 2004-09-15 14:37:40Z loubyansky $ -->
| <!-- ==================================================================== -->
| <!-- Datasource config for Oracle originally from Steven Coy -->
| <!-- ==================================================================== -->
|
|
| <datasources>
| <local-tx-datasource>
| <jndi-name>idmDS</jndi-name>
| <connection-url>jdbc:oracle:oci:@myDatabase</connection-url>
| <!--
|
| Here are a couple of the possible OCI configurations.

http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/java.92...
|
|
<connection-url>jdbc:oracle:oci:@youroracle-tns-name</connection-url>
| or
|
<connection-url>jdbc:oracle:oci:@(description=(address=(host=youroraclehost)(protocol=tcp)(port=1521))(connect_data=(SERVICE_NAME=yourservicename)))</connection-url>
|
| Clearly, its better to have TNS set up properly.

-->
| <metadata>
| <type-mapping>Oracle10i</type-mapping>
| </metadata>
| </local-tx-datasource>
|
| </datasources>
|
The datasource is injected in a stateful session bean:
Every time after I use this datasource in the login business method of the SFSB I get the
following exception:

I do not close the underlying connection of the datasource explicitly.
Does anyone know why this exception happens and if I should open/close connections in
datasources explicitly?
Thanks for helping.
