The warning category

The category of the warning of Signer.WarningListener.

  • Enum Constant Details

    • PDF_A_REMOVED

      public static final WarningCategory PDF_A_REMOVED
      PDF/A conformance of input file removed due to file encryption (i.e. pdftools.pdf.OutputOptions.getEncryption is not null). Removal of PDF/A conformance is necessary, because encryption is not allowed by the PDF/A standard.

    • SIGNED_DOC_ENCRYPTION_UNCHANGED

      public static final WarningCategory SIGNED_DOC_ENCRYPTION_UNCHANGED

      When processing signed documents, their encryption parameters (user password, owner password, permissions) cannot be changed. Therefore, the property pdftools.pdf.OutputOptions.getEncryption has no effect.

      This warning is generated so that the following situations can be detected:

      Encryption parameters of signed documents can be changed by removing all existing signatures using the property OutputOptions.getRemoveSignatures(). In this case, this warning is not generated.

    • ADD_VALIDATION_INFORMATION_FAILED

      public static final WarningCategory ADD_VALIDATION_INFORMATION_FAILED

      Error adding validation information to existing signatures of input document as requested by OutputOptions.getAddValidationInformation(). The warning's context contains a description of the affected signature.

      Potential causes of this warning are:

      • Missing issuer certificate: All certificates of the trust chain are required to add validation information. Preferably, the certificates should be present in the cryptographic provider's certificate store. Alternatively, if supported by the certificate, the issuer certificate is downloaded from the certificate authority's server and stored in the user's Certificates directory (see pdftools.crypto.providers.builtin.Provider).
      • Network problem: The network must allow OCSP and CRL responses to be downloaded from the certificate authority's server. Make sure your proxy configuration (see pdftools.Sdk.getProxy) is correct.

  • Method Details

    • values

      public static WarningCategory[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static WarningCategory valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null
