Intermittend connection problem from J2EE (separate) engine to ABAP

[Former Member]

When i run the test report FP_CHECK_DESTINATION_SERVICE the first time it works and returns the number of bytes transmitted. The second time it does not . The third time it works , the fourth time it does not etc etc etc No matter how long I wait in between the attempts so not random.

Any ideas would be helpfull.

The error i get on the java side is :

com.adobe.ads.destination.DestinationException: IO error detected while opening DEST connection: http://servername.domain.nl:4100/sap/bc/fp/form/layout/FP_TEST_00.XDP?fp-language=DE

After restarting the entire J2EE engine, this strange problem disappeared.
