RFC Login Problem

[Former Member]

Hi Friends,

I'm getting a problem when trying to connect to SAP ECC6 using JCO Program which is of 2.0.12 version. Error is <b>com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: Name or password is

incorrect (repeat logon)</b>. But i'm able to connect to SAP thru SAP GUI using the same userid. Can anyone plese specify if i'm missing anything.

Thanks in advance

What is your JCO version and R/3 version?.

Some system default configuratión change the login setings to Uppercase, and the last version of R/3 are case sensitive.

If the password is lowercase, RFC change to Uppercase and throw this exception

change the password in sap to uppercase and try again

Hi,

I'm able to solve this problem by reinitiating the password to all capital case characters and it got connected..

Thanks for your answers

Hi,

In addition to the above,

The reason why you get such errors is due to

Authorization failures during the logon phase usually caused by unknown username, wrong password, invalid certificates, etc.

The proposed solution is to

Get the logon data from the JAVA application or JCo trace that you get it always analyse it for correct logon details and use them...else

paste your Jco logs..I could analyse it..
