OSB Custom Transport Deployment Tips

I was developing custom transport for OSB, development of custom transport was relatively easy but deployment and troubleshooting was a bit of nightmare. Just sharing some tips as it might be useful for someone facing same issues:

• Deploy to both nodes (Adminserver and osb_server1)
  It seems like UI stuff is used from AdminServer, and it run time it uses code from osb_server1. (of course, if you have developer version of OSB install, that would be separate story).
  
  
• Redeploy of the transport always result in this error:

  Correct Re-deployment sequence
  
  
  1. Undeploy from EM
  2. Restart Admin and osb_server1
     Note: This is to completely get rid of transport registration. It will get rid of : Transport provider for ID *** already registered
     
  3. Redeploy to both Adminserver and osb_server1
     Note: execution of business service at this time will result in "null" error.
  4. Restart AdminServer and osb_server1
  
  
  
• May be there is way to configure System.out seperately for custom transport but OOTB System.out didn't work well, so better to use weblogic logger. (e.g. I used : weblogic.logging.NonCatalogLogger )
