JCo password error with ECC system.

[Former Member]

Hi

We have developed java application to connect to SAP systems for some data extraction. This application is working fine with older versions SAP 4.7 etc.

But now we are facing issues with the ECC system. When we are trying to connect to ECC system its giving error "Error: Name or Passowrd is incorrect (Repeat logon)". But we are able to login to ECC system through SAP GUI using the same userid and password.

If we change the password with all UPPERCASE (letters), it is working fine in java application also.

Please suggest!

Thanks & Regards

Hi Kishore

Ideally the user to be used for JCo connections should be a RFC user, defined as type "comunication" in TCode SU01.. the user with which you log into GUI is of type "dialog". So, create a user of type "communication" and place this user in CAPS (hope u already know this, it being a Java code)..

Let me know if it works ..

I face the same problem.

I resolve the same by appending IP & Host name in host file.

Please modify your host file Path :Start->drivers click then go to etc folder and edit your Host File. Or tell your basis person to do the same.
