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

Question

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/tcwddispwda, sap.com/tcwdcorecomp).
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

Hi,
   Have you made the configurations to determine the JNDI name of the BI XMLA connector?
   Just check if you have done these steps:
1. Open Visual Administrator.Select
<server node>
->Services
->JNDI Registry.
On the Runtime tab, in the registry list, locate deployedAdapters
->SDK_XMLA
->shareable
->SDK_XMLA.
This path, from the root to the SDK_XMLA leaf node, indicates the fully-qualified JNDI name of the BI XMLA Connector,which is:"deployedAdapters/SDK_XMLA/shareable/SDK_XMLA".
2. Select the server node, and choose
<server node>
->Services
->Connector Container.
3. Locate and double-click the entry for the BI XMLA Connector,sap.com/com.sap.ip.bi.sdk.dac.connector.xmla.BI_SDK_XMLA, to open the connector definition.
4. Select Managed Connection Factory->Properties, and set
the required connection properties as shown
Property:Setting
DataSource:default
Statefulness:false
Language:EN
Password:(password)
UserName:(username)
URL:http://server:port/sap/bw/xml/soap/xmla
In order to find out this URL,f or a BW system, start transaction SE37 and execute the function module RSBB_URL_PREFIX_GET.
Use the following values for the import parameters of the function module:
I_HANDLERCLASS = CL_RSR_MDX_SOAP_HANDLER
I_PROTOCOL = HTTP
I_MESSAGESERVER =
The URL takes the following form: */sap/bw/xml/soap/xmla.
5. Save the settings.
