FAQ

• Alternatives are not returned for every risk.

  Only individuals of type SystemSoftware that are defined in the passed ontology or in direct imports thereof are considered.
  The risk is silently skipped if the individual could not be found.

• The knowledgebase is unavailable.

  Have a look at the kbgen project to rebuild the knowledgebase or obtain a copy.

• The query runs forever and stops eventually with an exception.

  Make sure that no self-signed certificates are imported in the ontology that is passed.
  If there are such:

  • download the certificate (e.g. in firefox)
  • create a keystore:
    keytool -import -file [cacert.pem] -alias [alias] -keystore [keystore.ts] -storepass [password]
  • load the keystore:
    System.setProperty("javax.net.ssl.trustStore", "/tmp/pi/keystore.ts");
