BI SDK in Web Dyn Pro- Can't open Connection

hello,

I am developing a Web DynPro component which should connect to a BW 3.5 via BI SDK - XMLA.

As a start i just use the code from the "How to " document for Web DynPro without any changes.

I could deploy the application and it should give me the list of the schemas. instead it returns "Can't open Connection" .

I looked in the Web DynPro Content Administrator and found that the Reference "sap.com/com.sap.ip.bi.sdk.dac.connector.xmla" has under the Status a red light; there are 2 other with green

(sap.com/tc_wddispwda, sap.com/tc_wdcorecomp).

Since red lights are never a good sign, i would like to know what is the reason for it and how can i fix it ?

I assume there is a direct connection between the "Can't Open Connection" and the red light...

Any useful help is appreciated and will be rewarded 😊
