[jboss-dev-forums] [Design of JBoss ESB] - Original file name as message property for File/FTP gateways
I have some code that adds the originating filename as a property on messages coming from
file or FTP gateways. In our business case, we needed to be able to take the original
filename, modify it with a timestamp and use that as the filename on an outgoing FTP. Our
solution was an action that executes a chain of strategies on the incoming filename,
passing the end result to a NotifyFTP action. The config looks like this...
| <jbossesb parameterReloadSecs="5"
xmlns="http://anonsvn.labs.jboss.com/labs/jbossesb/trunk/product/etc...
| <providers>
| <jms-provider name="JBossMQ"
connection-factory="ConnectionFactory" jndi-URL="localhost">

error-suffix=".esbERROR"/>
| </fs-bus>
| </fs-provider>
| <ftp-provider name="MyFtpProvider"

| </ftp-bus>
| </ftp-provider>

| <strategy

| </strategies>
| </property>
| </action>
| <action name="SendToFTP"
class="org.jboss.soa.esb.actions.Notifier">
| <property name="okMethod" value="notifyOK"/>
| <property name="notification-details" value="">
| <NotificationList type="OK">
| <target class="NotifyFTP">
| <ftp URL="ftp://user:password@server.com/home/user"
filename="{org.jboss.soa.esb.naming.result}"/>
| </target>
| </NotificationList>
| </property>
| </action>
| </actions>
| </service>
| </services>
| </jbossesb>
The FileNameGeneratorAction uses the message property for originating filename set in the
gateway by default (can be changed via action props) and writes the result to a well-known
message prop name. The NotifyFTP action picks up the result value and uses that as the
filename it writes.
I figure that this may be helpful to other people with similar requirements, so I was
wondering if I should check the code in. Alternatively, I can add a JIRA and attach the
updates so people can take a look before it goes in the trunk.
Thanks,
Derek
