<SAP:Stack>Error while sending by HTTP (error code: 503 , error text: Service Unavailable) (See attachment HTMLError for details)</SAP:Stack>


I can see the following contents in attched HTMLERROR file

While trying to retrieve the URL: http://XXXXXXXX/MessagingSystem/receive/AFW/XI

The following error was encountered:

Unable to determine IP address from host name for paymentdev

The dnsserver returned:

Name Error: The domain name does not exist.

This means that:

The cache was not able to resolve the hostname presented in the URL.

Any solution to resove this issue.

For the generic description, please see:

Error: The error message 503 Service unavailable Application stopped! is displayed.

Description:The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay MAY be indicated in a Retry-After header. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response.

Note: The existence of the 503 status code does not imply that a server must use it when becoming overloaded. Some servers may wish to simply refuse the connection.

Possible Tips: Because of J2EE application not active

u2022 Try to (re)start the application using the Visual Administrator Choose Server --> Services --> Deploy --> View on Application or restart the J2EE engine

u2022 The problem is that not all J2EE services can be started by the J2EE. i.e Start the Visual Administrator and select Server->Services->Deploy in the tree on the left. On the right-hand side, choose the Runtime tab page. You see a tree in the right window with all applications if you select the APPLICATION radio button. Check if they are running, otherwise choose Start. Usually the J2EE engine starts all services automatically.

u2022 Refer SAP Note 803145,807000,791655

Also, check if the J2EE is up and properly working.

Did you checked with the network /basis team...looks like some ports need to be opened or need to map details (like the Firewall...)

you can chase down Network team for quick response on this..Also check the port configured are correct...
