Error while Testing JCo Connections.

Hi Gurus,

when we are testing JCO Connection the error we are getting is

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

i.e for SAP_R3_Financials we are getting this error, SAP_R3_Finalcials_MetaData the test was sucessful

with MetaData the connection is successful but comming to application data it is throwing error.

throw some light on this.

also when i am clicking the ess page i am getting 500 internal server error.

Note: SSO is working fine.

Regards
