java.sql.SQLException: JZ00L: Login failed

1103 Views

Hi ,

I am trying to connect to a Sybase ASE Database using attached java Program. I have tried it with jconn4-7.0.7.jar , jconn4d.jar library one by one but unfortunately nothing works .

Environment :

OS : SUSE Linux Enterprise 12 SP4

Sybase ASE version : Sybase ASEv 16

java version "1.8.0_91"

I'm executing this connection like below :

javac -cp .:jconn4d.jar GetSybaseConnection.java

java -cp .:jconn4d.jar GetSybaseConnection

Enter Sybase Database UserName : xxxx

Enter Sybase Database Password : xxxx

where I got this below Stack trace while connecting to Sybase driver from code :

Exception in thread "main" java.sql.SQLException: JZ00L: Login failed. Examine the SQLWarnings chained to this exception for the reason(s).

I'm very sure about Hostname , port , username and password .

I tried this connection using DbVisualizer tool but there also it didn't work and throws below error An error occurred while establishing the connection:

One strange thing is that using isql tool I'm able to connect to Sybase Database using below command .

isql -S SERVERNAME -U USER -P xxxxxxx -X

I'm suspecting that is there any configuration we have perform from Sybase database configuration side ?

Do you see any reason regarding this weird connection behavior? Please let me know, if you need further information.

Please find attached Java Programme. sybase.png
