I am happy to announce that UNICORE client with Genesis II endpoint success in all RByteIO operations. But, in test 5.3, SByteIo seekRead operation didn't return the expected result. Genesis output from the test 5.3 is, - output text "141516171819202122232425262728293" - encoded text, "MTQxNTE2MTcxODE5MjAyMTIyMjMyNDI1MjYyNzI4MjkzMA==" The expected output should be, - output text "01020304050607080910++++++1415161718192021222324252627282930" - encoded, "MDEwMjAzMDQwNTA2MDcwODA5MTArKysrKysxNDE1MTYxNzE4MTkyMDIxMjIyMzI0MjUyNjI3MjgyOTMw" Concerning UNICORE endpoint, UNICORE endpoint is up, Genesis II client can retest the SByteIO operations. Thanks Mark for pointing out WS-Addressing and seek-origins' pointers. -- ------------------------------------------------------------------------ Mohammad Shahbaz Memon Department of Applied Mathematics Forschungszentrum Jülich GmbH Jülich Germany Skype: m.memon Web page: http://www.fz-juelich.de/zam/ZAMPeople/memon_m Office: +49 (0)2461 61 6567 Fax: +49 (0)2461 61 6656
