Description

I have a desire for new trasnport in Axis2/C.

I found a hard cording the transports in axis2_const.h like this.

#define AXIS2_TRANSPORT_HTTP "http"
#define AXIS2_TRANSPORT_SMTP "smtp"
#define AXIS2_TRANSPORT_TCP "tcp"
#define AXIS2_TRANSPORT_XMPP "xmpp"
#define AXIS2_TRANSPORT_HTTPS "https"

typedef enum
{
AXIS2_TRANSPORT_ENUM_HTTP = 0,
AXIS2_TRANSPORT_ENUM_SMTP,
AXIS2_TRANSPORT_ENUM_TCP,
AXIS2_TRANSPORT_ENUM_XMPP,
AXIS2_TRANSPORT_ENUM_HTTPS,
AXIS2_TRANSPORT_ENUM_MAX
} AXIS2_TRANSPORT_ENUMS;

And using like this.

/**

• Adds a transport in description.
• @param conf pointer to conf struct
• @param env pointer to environment struct
• @param transport pointer to transport in description. conf assumes
• ownership of the struct
• @return AXIS2_SUCCESS on success, else AXIS2_FAILURE
  */
  AXIS2_EXTERN axis2_status_t AXIS2_CALL
  axis2_conf_add_transport_in(axis2_conf_t *conf,
  const axutil_env_t *env,
  axis2_transport_in_desc_t *transport,
  const AXIS2_TRANSPORT_ENUMS trans_enum);

If we want to add a new transport, we must defin a transport in axis2_const.h and re-build Axis2/C modules.
In Axis2 (Java), we don't need to re-build Axis2 modules, if we think so.
We can only provid a class implemented TransportProvider I/F and add a entry at axis2.xml file.

Axis2 said in key features, engine is completely transport-independent at "Transport Fremework".
I think the realization like Axis2 is advisable.
