ClassCastException on DB Adapter

Question

Hello Gurus - maybe some of You know solution.
Configuration: jDev 11.1.1.2, SOA Suite 11.1.1.2, WL 10.3.2
JDBC cofiguration: well, standard jdbc/XX1 with driver class name oracle.jdbc.xa.client.OracleXADataSource
DBAdapter outbound connection pool configuration (eis/DB/XX1):
dataSourceName     java.lang.String     jdbc/XX1
defaultNChar     java.lang.Boolean     false
platformClassName     java.lang.String     oracle.toplink.platform.database.Oracle9Platform
sequencePreallocationSize     java.lang.Integer     50
usesBatchWriting     java.lang.Boolean     false
usesNativeSequencing     java.lang.Boolean     true
usesSkipLocking     java.lang.Boolean     true
Yes yes - tried all kind of configuration possibilities with DB Adapter Update and WL/SOA restart.
So here is error I got:
DBActivationSpec Polling Exception.
Query name: [XXXX], Descriptor name: [XXXX]. Polling the database for events failed on this iteratio
n.
Caused by java.lang.ClassCastException: oracle.tip.adapter.db.DBConnectionFactory cannot be cast to javax.sql.DataSource.
This exception is considered not retriable, likely due to a modelling mistake. This polling process will shut down, unless the fault is r
elated to processing a particular row, in which case polling will continue but the row will be rejected (faulted).

At the same time from another machine deployed stuff is working. There could not be any difference in machine configuration as error appear on server only.
Here are rest of files:
<adapter-config name="XXX" adapter="Database Adapter" wsdlLocation="XXX.wsdl" xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">
<connection-factory location="eis/DB/XX1" UIConnectionName="1234567890" adapterRef=""/>
<endpoint-activation portType="..." operation="...">

<property name="SequencingColumn" value="ID"/>

<property name="SequencingTableValueColumn" value="123"/>

<property name="SequencingDataSourceName" value="eis/DB/XX1"/>
<property name="SequencingIsXADataSource" value="true"/>
<property name="PollingInterval" value="300"/>
<property name="MaxRaiseSize" value="1"/>
<property name="MaxTransactionSize" value="10"/>
<property name="NumberOfThreads" value="1"/>
<property name="ReturnSingleResultSet" value="false"/>
</activation-spec>
</endpoint-activation>
</adapter-config>
mappings/properties files looks fine as well - no external or changed libraries referenced.
So the question is - what might me reasons for "Caused by java.lang.ClassCastException: oracle.tip.adapter.db.DBConnectionFactory cannot be cast to javax.sql.DataSource."

Answer 1

JDBC cofiguration: well, standard jdbc/XX1 with driver class name oracle.jdbc.xa.client.OracleXADataSource
DBAdapter outbound connection pool configuration (eis/DB/XX1):
dataSourceName java.lang.String jdbc/XX1You have created a XA datasource. In connection pool configuration, provide the data source JNDI name in property "XADataSourceName" instead of "dataSourceName"
