Enable display of SSL-secured feeds

When using IBM Syndicated Feed Portlet for WebSphere Portal, some feeds that use HTTP over SSL (HTTPS) may not function properly due to missing SSL certificates. You may encounter errors, such as Missing certificate, Unknown certificate, or Untrusted certificate because of missing root signer certificates or missing self-signed certificates in the WAS certificate trust store. In both the cases, add the appropriate certificates to the WAS certificate trust store in use for your WebSphere Portal Server installation.

In order to add the appropriate certificates, you will require Administrator access to the WAS for your WebSphere Portal Server installation.

To add the missing certificates:

  1. Obtain the missing certificates.

    First, obtain the missing certificate. There are various mechanisms for doing this depending on the type of certificate that is missing.

    In general, the quickest way to obtain the missing certificate is to access the feed you are trying to add directly from a Web browser. All modern browsers provide the capability to view a certificate and its trust chain. However, the directions for viewing and exporting certificates from a Web browser are browser vendor specific and therefore outside the scope of this document (except to say that they should be exported in Base-64 encoded format as a file with the extension .cer or .arm). If you need assistance with this task, please contact your IT administrator. There are also many online resources that can help you perform this task.

    In the case of self-signed certificates, you may be prompted with several warnings regarding the acceptance or trust of this certificate. In such cases, please ensure that you trust the third-party server before adding the certificate to your WAS certificate trust store.

  2. Once you have exported the appropriate root signer or self-signed certificate, please refer to the instructions in the Adding a signer certificate to a keystore topic of WAS InfoCenter to import the root signer certificate or to import the self signed certificate as a new trusted signer certificate to the appropriate trust store.

  3. Restart WebSphere Portal Server.
