Hi Ram,

SAP Java Connector (SAP JCo) is a middleware component that enables the development of SAP-compatible components and applications in Java. SAP JCo supports communication with the SAP Server in both directions: inbound calls (Java calls ABAP) and outbound calls (ABAP calls Java).

Error: com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'WD_FLIGHTBOOKING_RFC_METADATA_DEST' in the SLD. No such JCO destination is defined in the SLD.

Please create and enable the JCO's in SAP Webdynpro content adminsitrator:

Navigate to Content Administration>webdynpro>Jco Destination-->here u can find out all the JCOs u r maintaining.

Select the respective JCO and click Test ,if it is properly created u will get a success message.

All the JCOs created are maintained in SLD.

Hi Ramu,

The JCO destinations that you enter when you create FlightBooking model. The JCO destinations must be available and running in the Portal. Check this [link|http://help.sap.com/saphelp_nw04/helpdata/en/07/a01440a1c32402e10000000a1550b0/frameset.htm] to know more about JCO destinations and how to create.

CHECK WITH YOUR admin.

if it is active then deploy again.
