Hello.

Thats one service in my jboss-esb.xml

<service category="de.eskalon.kn.garuda.invoice.HistoricalExchangeRates" name="HistoricalExchangeRateImporter" description="Imports historical exchange rates from ftp directory files" invmScope="GLOBAL">

 <service category="de.eskalon.kn.garuda.invoice.HistoricalExchangeRates" name="HistoricalExchangeRateImporter" description="Imports historical exchange rates from ftp directory files" invmScope="GLOBAL">
            <listeners>
                <ftp-listener busidref="currency-ftp-in" is-gateway="true" maxThreads="2" name="ftp-listener-gateway"  scheduleidref="everyminute" />
                
            </listeners>
            <actions mep="OneWay"> 
                 <action name="transform" class="org.jboss.soa.esb.actions.converters.ByteArrayToString">
                    <property name="encoding" value="UTF-8" />
                </action>
                 <action name="properties" class="de.eskalon.kn.garuda.esb.GetPropertiesFromMessage"> </action>                
                <action class="org.jboss.soa.esb.actions.EJBProcessor" name="callPersist">
                    <property name="ejb3" value="true" />
                    <property name="jndi-name" value="garuda-invoicing/HistoricalExchangeRatesManagerBean/remote" />
                    <property name="initial-context-factory" value="org.jnp.interfaces.NamingContextFactory" />
                    <property name="provider-url" value="localhost:1099" />
                    <property name="method" value="persistRate" />
                    <property name="ejb-params">
                        <arg0 type="java.lang.String">FILE_NAME</arg0>
                        <arg1 type="java.lang.String">org.jboss.soa.esb.message.defaultEntry</arg1>                        
                    </property>                  
                </action>
            </actions>
        </service>
            <listeners>



And here my ftp-provider 


 <ftp-provider hostname="${currency.ftp.host}" name="currency-provider">
            <ftp-bus busid="currency-ftp-in">
                <ftp-message-filter directory="${currency.ftp.directory}" error-delete="false" error-suffix=".HAS_ERROR"
                                          input-suffix=".csv"
                          passive="true" password="${currency.ftp.password}" post-delete="false" post-rename="true"
                         post-suffix=".COMPLETE" username="${currency.ftp.username}" work-suffix=".garudaWorking" />
            </ftp-bus>
</ftp-provider>




So its possible tthat something goes wrong in my persistRate method. But in any case the ftp-listener will rename the file to <filename>.COMPLETE independently of throwing an exception in my method. So my question is how do I handle this correctly. What I want to have is, if anything goes wrong rename the file to <filename>.HAS_ERROR

Best regards

Phillip
