Description:
In BW 6.x, using Send HTTP Request palette to access Google Calendar API using SSL. The palette is linked to a  SSLClientResource. The SSLClientResource is linked to a keystore configuration. The keystore is configured as follows:

key store provider=SUN
type= JKS

BW throws the following error:

   <CausedBy> Activity [SendHTTPRequest] fault.  

   <CausedBy> com.tibco.bw.palette.http.runtime.exceptions.HttpCommunicationException: TIBCO-BW-PALETTE-HTTP-500013: An IOException was thrown while trying to execute the Http method-{ActivityName=SendHTTPRequest, ProcessName=googlecalendarlistenerbw.getGoogleCalendarEventsREST, ModuleName=GoogleCalendarListenerBW.module}

Symptoms:

Cause:
certificate chain is not complete

The error is caused by an incomplete certificate chain in the keystore. To resolve this error, do the following:

Access Google Calendar API in Firefox. Export the three certificates:

- GeoTrustGlobalCA
- GoogleInternetAuthorityG2
- *.google.com

then import all three into the JKS file.  

keytool -importcert -alias GoogleInternetAuthorityG2 -keystore my.jks -file /Users/GoogleInternetAuthorityG2.pem

keytool -importcert -alias GeoTrustGlobalCA -keystore my.jks -file /Users/GeoTrustGlobalCA.pem

keytool -importcert -alias *.google.com -keystore my.jks -file /Users/\*.google.com.pem

Unable to find a valid certification path to a requested target.
