Error Handling in File Adapter

Question

I have been working on a requirement where the file adapter picks up the file and gives to the BPEL for processing the data.
So, in order to do Error Handling for file adapter, i have been reading the Oracle documentation for technology adapters. In that, some of the
points which i felt valuable for my error handling when using file adapter are the uniqueMessageSeparator property, fault-policies for rejected messages,
and one of the action for rejected messages could be writing the payload to a file or invoking any other webservice.
In my composite, i have configured the file adapter as a service for reading files, and i defined the xsd using the native format builder....If i put some data like 'aaaa' in the attribute of type integer , the .csv file is being picked up and its being passed to the BPEL without any error ? I believe there should be a translation error...right...
But i am not getting the error, please tell me if anything is wrong in my xsd....
Here is my xsd...
<?xml version="1.0" encoding="UTF-8" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:nxsd="http://xmlns.oracle.com/pcbpel/nxsd"

nxsd:encoding="US-ASCII"
nxsd:hasHeader="true"
nxsd:headerLines="1"
nxsd:headerLinesTerminatedBy="${eol}"

<xsd:element name="name" minOccurs="1" maxOccurs="unbounded">

<xsd:sequence>
<xsd:element name="FirstName" type="xsd:string" nxsd:style="terminated" nxsd:terminatedBy="," />
<xsd:element name="LastName" type="xsd:string" nxsd:style="terminated" nxsd:terminatedBy="," />
<xsd:element name="Number" type="xsd:integer" nxsd:style="terminated" nxsd:terminatedBy="${eol}" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
And for DB Adapter, there is a property called SchemaValidation, i think that is not there for File adapter, by default it will take care of validation i guess....In another composite, my file adapter is picking up the .xml file and if i put any wrong data over there, that is working fine, i am getting the translation error, but only here in the case of csv file, i am not getting the error. Experts, please help me in this regard...I am using SOA 11G

Hi Yatan,
Thanks for the reply. I did the same way, where my composite is picking up an XML file and translation error is coming. Even the fault policies are working fine, like writing to a file and even invoking other web service. Its really good that you have achieved the same thing in csv files. But the same thing i am unable to achieve when my file adapter is picking up the csv file. I really cant understand where i am doing wrong.
here is my XSD which i defined through my native builder format...
<?xml version="1.0" encoding="UTF-8" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:nxsd="http://xmlns.oracle.com/pcbpel/nxsd"
xmlns:tns="http://TargetNamespace.com/FileRecv"
targetNamespace="http://TargetNamespace.com/FileRecv"
elementFormDefault="qualified"
attributeFormDefault="unqualified"
nxsd:version="NXSD"
nxsd:stream="chars"
nxsd:encoding="US-ASCII"
nxsd:hasHeader="true"
nxsd:headerLines="1"
nxsd:headerLinesTerminatedBy="${eol}"

the jca file ..
<adapter-config name="FileRecv" adapter="File Adapter" wsdlLocation="FileRecv.wsdl" xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">
<connection-factory location="eis/FileAdapter" UIincludeWildcard="n*.csv"/>
<endpoint-activation portType="Read_ptt" operation="Read">
<activation-spec className="oracle.tip.adapter.file.inbound.FileActivationSpec">
<property name="DeleteFile" value="true"/>
<property name="MinimumAge" value="0"/>
<property name="PhysicalDirectory" value="C:\files"/>
<property name="Recursive" value="false"/>
<property name="PollingFrequency" value="5"/>
<property name="IncludeFiles" value="n.*\.csv"/>
<property name="UseHeaders" value="false"/>
</activation-spec>
</endpoint-activation>
</adapter-config>
I told that the file will contain only 1 record while defining xsd and i kept a record whose values are John , Peter and akjdkjdskj.
Now if the data is like above, the file is still getting picked up without any translation error and the BPEL is getting completed successfully...
Is it possible for you to send your sample project and the csv file from which you have defined the xsd to me if you dont mind ?
Thanks,
