Hi,
Please prepare with more patience as my message is too big 
Am configuring SNC in JAVA system to connect the ABAP system.
I performing the attached document steps. (SNC J2EE_To_ABAP. PDF) but I got stuck in the Jco destination creation which is failing with below error.
----------------------
- com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: connection closed without message (CM_NO_DATA_RECEIVED)
----------------------
During my searching process I come to know that UME has to be configured to connect the ABAP system. Hence I followed the UME configuration steps accordingly as per the UME to J2EE attached document Only followed the LDAP to ABAP connectivity steps.
But after I updated the UME parameters J2EE server is not coming up. It is failing with below error.
std_server0.out

-----------------------------------------
Everytime it was showing different issues, as perthat I did many changes, Now it is failed with above error. I do not think this is only problem with SECUDE.dll.
Key points which needs to tell.
- Below line is added in .sapenv_lhvzhjad.csh
setenv SECUDIR /usr/sap/HJE/JC01/sec
And below line is added in .sapenv_lhvzhjad.sh
SECUDIR=/usr/sap/HJE/JC01/sec/; export SECUDIR
- Do we need to create any RFC from ABAP system side to communicate with JAVA via SNC. ?
- UME is needed for SNC configuration ?
- How the Jco destination will communicate with ABAP as I didnt create any RFC in ABAP side.
Kindly check the issue and help me to move further.
Thank you so much guys,
Madhan
