Can not connect to BW IDES with JCo

[Former Member]

I am trying to test out the JCo and preparing for coming project, however, the simple java program I created always gives me exception while trying to connect to IDES server

Here is the exception I got

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

I am 100% sure the user name and password is CORRECT, and SAP Logon to the same server works fine.

I also tested the same code (with different server configuration) on other BW system (non-IDES), which works perfectly fine.

Tried to search the forum and didn't get any clear solution.

The only matter I concerned is Java is not active on the (IDES) application server.

So does JCo supports connect to BW IDES system? Is java required to be activated on server so that JCo can connect to?

Thanks for any reply.

thanks for your reply, I went through the guide and didn't find more useful information for my case. I didn't use any sso/ticket for login the only one are username/password. with same login information, I can connect to the server in sap logon (frontend) but not in my java program through JCo.

BTW, my JCo version is 2.0 and it worked fine with another server.

Hi Joe,

I faced similar issue few months ago and I able to resolve it. I have just changed the password to uppercase of the user and i got connected to the SAP Backend system via JCO.

Say for example if you are entering the password: root

change this to : ROOT

This thread was explining the same issue, and they resolved it.

Thanks

I guess it is not the case issue of password since this only happens for earlier version of Server. I worked with some of my colleagues and figured there is something with the client ID got miss configured. After I correct it on my code, the connection works fine now.

Thanks a lot for your replies.
