Calling a HTTPs POST REST url web service which is SSL Certificate Secured Oracle Service Bus OSB

In one of my projects, I had a requirement to call a web service which was a REST service and I had to POST XML content to the web service. The web service URL demanded to query parameters though and the service only wanted a XML to be POSTed.
The service was Certificate SSL secured with HTTPs basic authentication.

So here are the steps which I did using Oracle Service Bus.

Firstly, I went to the UNIX box the ran the below command to load the certificate from the web service.
I used the openssl utility to load the certificate. Other option is any browser to do the same. The certificates nature vary from being a chain of certificates being CA signed or a single self- signed certificate. In my case it turned out to be a single self signed certificate.
Here is the command -

openssl s_client -connect host:port | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /..../somename.cert

Once the certificate was loaded. I had to loaded it up into the keystore of weblogic. To load it, I used the keytool utility.

Loading into the Java Keystore -

keytool -import -trustcacerts -keystore /appl/oracle/dev/fmw/11g/java/jrockit-jdk1.6.0_81/jre/lib/security/cacerts -noprompt -alias somealias -file somename.cert



Loading into the Default weblogic demoTrust keystore. Note, for production, it can be the Custom Trust store.

keytool -import -trustcacerts -keystore /appl/oracle/dev/fmw/11g/product/wlserver_10.3/server/lib/DemoTrust.jks -noprompt -alias somealias -file somename.cert

and the work for the certificate part was done.

Now, since the service was HTTPs basic authentication secured too, so an OSB Service Account was used to provide a static username and password and associate it with the Business Service.

After create the Business Service, I had too only put the XML content in the Request panel and the work was done.
