WSO2 ESB supports vfs transports which is based on  the Apache Commons VFS implementation WSO2 ESB supports many service level parameters in synapse configurations. Following are 3 service level parameters which you can use for protecting your files being transferred. PASSIVE MODE Passive mode is generally used in situations where the FTP server is not able to establish the data channel. One of the major reasons for this is network firewalls. While you may have a firewall rule which allows you to open up FTP channels to ftp.wso2.com, WSO2's servers may not have the power to open up the data channel back through your firewall. Passive mode solves this by opening up both types of channel from the client side. IMPLICIT MODE FTP over SSL (Implicit) Implicit security is a mechanism by which security is automatically turned on as soon as the FTP client makes a connection to an FTP server. In this case, the FTP server defines a specific port for the client (990, Can be...

WSO2 ESB supports many mediators, and we can use them to achieve most of our use cases.

And you might need to remove the soap header element including <soap:Header></soap:Header> element. You can achieve this by using enrich mediator and payload factory mediator. We first extract the body from the soap envelop and assign it to a property using enrich mediator. Then we create an empty soap envelop using payload factory. At last enrich m...
