WSO2 ESB - Calling a VFS Transport from a Scheduled Task

Question

I need to run a VFS Transport at a specific time of the day, so to me the obvious solution seems to be calling it from a CRON-style Scheduled Task.

According to my internet searches this seems to be possible but as I'm quite new to WSO2 ESB haven't found a way to get this done yet.

Is this really possible?
If so, can you please point me in the right direction?

Answer 1

A solution would be to write your own task / class / javascript / mediatior

You should have a look at https://docs.wso2.org/display/ESB481/Writing+Tasks+Sample : This custom task sample cover something similar to your needs

An other sample based on a javascript that look if a file exist :

    <script language="js">
    importPackage(Packages.org.apache.commons.vfs2);
    if(VFS.getManager().resolveFile("smb://DOMAIN\\user:password@hostname/dir/myfile.xml").exists()){
      mc.setProperty("THIS_FILE_EXIST","true")
    } else {
      mc.setProperty("THIS_FILE_EXIST","false")          
    }
    </script>

VFS transport does not support cron expressions..You can define polling interval in seconds
