Unable to login using JCO

On trying to connect using JCO I'm getting the below error:

com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: Name or password is incorrect (repeat logon)

at com.sap.mw.jco.rfc.MiddlewareRFC$Client.nativeConnect(Native Method)

at com.sap.mw.jco.rfc.MiddlewareRFC$Client.connect(MiddlewareRFC.java:589)

at com.sap.mw.jco.JCO$Client.connect(JCO.java:2235)

The username, password is given correctly.

Password contains a special character '@'. Is it of any importance?

Hello there,

Are you able to login to the ECC directly. Just Reset your password with another one and give it a try.

Hi Vivek,

Logging from ECC was successful. On changing password to a word that didn't have '@', it worked fine.

Hi Prathima,

Glad that the tip helped. Please make sure you store the passwords on a encrypted properties file.
