If you get the above exception in your Eclipse . PLease follow the steps below to remove this. BTW this happens because the HTTPClient does not have the certificate sent by the server in its trusted certificate list.

1) Download Portecle (google it). It is a java tool for importing certificates.




2) Go to the URL the HTTPClient is pointing to eg: https://wsgx-dev.xyz.com in forefox. It will give some validation error on the page . That is fine . Just click on the left to the URL in the browser URL and you will see the certificate dialog. The process is shown above. Finally click on export and save it on your file system.

3) Now go to C:\Program File \java \ jdk1.xx\ jre \lib\security [Path for jdk i am using for my eclipse] and open the file cacerts. This is the file which contains the certificates for jdk on my machine.

Open cacerts with portecle . It will ask for password which is : changeit . Now import the trusted ceritficate from the file system where you saved your cetificate earlier. Save the keystore.

Now you should be able to run your program and it will not give the erro.
