Try "Starting and Stopping External Servers":

s st=$system.external.startServer("%Java Server")

Hi,

you can start it using

do ##class(%Net.Remote.Service).StartGateway("%Java_Server")

Thanks you very much that one worked.

The reason why I'm asking this is because I'm using the below code to connect & download files from AWS and it works fine but after using it say 100 times it stops and can not create the client, and if I stop & start Java Server it start working again not sure why !?

   set file="/Persistent/US-SERENITY/AWSCredentials"
   set endpoint="https://s3.amazonaws.com"
   s tStatus=""
   s output=""
   s res=##CLASS(%Net.Cloud.Storage.Client).CreateClient(,0,file,"us-east-1",.tStatus,endpoint)
    s list=res.ListBuckets()
   set list=res.ListBlobs("vibjson")
        if (res.BlobExists("vibjson",JobId_".json.gz"))
        {
   d res.DownloadBlobToFile("vibjson",JobId_".json.gz","/Persistent/S3DOWNLOADS/"_JobId_".json.gz")
   S output="/Persistent/S3DOWNLOADS/"_JobId_".json.gz"
        }

       D res.Close()
   q output

I agree - $system.external is the correct interface. You should be able to find out more about the $system.external interface by calling $system.external.Help().
