JAVA Connect SNC with error: No credentials were supplied

[huiyong_tan]

Hi Experts

I have an error when I try to connect SAP with SNC by sapjco3.jar lib,

the system environment is ok, because other SAP account working, I have tested already.

the configuration as bellow:

1. system32 folder put the sapjco3.jar and sapjco3.dll

2. the code specifies the dll SNC_LIB path:

3. and then run the jar application, got error as bellow:

4.this error only for one account, and other SAP account is ok for same system, I don't know where went wrong, maybe the cert configuration or SAP SNC server configuration. and I asked the local SAP supplier, but never replied.

some configurations as bellow:

import certification: sapgenpse import_own_cert

add certification user: sapgenpse.exe seclogin

Any help will be appreciated. Thanks!

By the way, if the users use the classic authentication (user + password) they can log into the system with no problem.
