Web dynpro sld / jco setup

Question

hi,
i have an erp system installed. on my local computer i installed the netweaver developer studio. i build the flights example from sap. after building and running the application an error occures:
The initial exception that caused the request to fail, was:
   com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'WD_RFC_METADATA_DEST' in the SLD. No such JCO destination is defined in the SLD.
    at com.sap.tc.webdynpro.serverimpl.wdc.sl.JCOClientConnection.resolveConnectionParameter(JCOClientConnection.java:467)
    at com.sap.tc.webdynpro.serverimpl.core.sl.AbstractJCOClientConnection.init(AbstractJCOClientConnection.java:233)
    at com.sap.tc.webdynpro.serverimpl.core.sl.AbstractJCOClientConnection.<init>(AbstractJCOClientConnection.java:218)
    at com.sap.tc.webdynpro.serverimpl.wdc.sl.JCOClientConnection.<init>(JCOClientConnection.java:129)
    at com.sap.tc.webdynpro.serverimpl.wdc.sl.SystemLandscapeFactory.getJCOClientConnection(SystemLandscapeFactory.java:150)
so, i want to configure the jco. but on the page where i can do it, it says that my sld could not be open. in the visual administrator i set the http settings. and i tried to open the sld in browser, but it says that i have no authority for this.
but i logged in with the j2ee admin, which i gave the sap_sld_administrator rights too.
do you know what went wrong?

Hi Marcus,
If you are using UID/PWD mapping for JCO destination please check wether you have provided correct uname and password.
If you are using SSO instead of UID/PWD mapping then check wether SSO is working properly between portal and ECC.
Mostly this problem is due to authorization failures during the logon phase.
Please check if the SAP user-id & password you are using to connect to the SAP system are correct.
Get the logon data from the JAVA application or JCo trace
for the error description visit,

Have a look at the solution provided in the below threads :
1>Re: com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: Incomplete log
2>JCO Error
Hope this helps you.
