Description

The Directorate-General for Informatics (DIGIT) is happy to announce the upgrade of the sample implementation of the SML software in order to fully support the CEF eDelivery SML specification. In version 4.0.x, as in version 3.1.x the SML will also provide support for the e-SENS BDXL profile, as well as the PEPPOL SML specification. As the PEPPOL SML specification continues to be supported, current users of the SML software shouldn't suffer of any disruption of service. The SML managed service offered by DIGIT uses this sample implementation and therefore benefits from its features.

This version of the SML sample implementation is also known as Business Document Metadata Service Location application (BDMSL). It is released with additional documentation which can be found below.

The SML 4.0.2 release was focused in improving stability of SML for the case where one SMP could have more millions participants.  Identified problems were methods where participants are listed (possible out of memory issues and long duration of execution with possible TTL exceptions). The new release includes following upgrades compared to release 4.0.1:

  • Option to disable listDNS method for a large number records in DNS.

  • New simple tools to check/validate if participant is registered in DNS.

  • Rewritten inconsistency report generation to use temporary files instead of keeping all dns and database records in memory for to compare.

  • Administrators can define max count of participants registered on SMP where participants are automatically deleted or DNS records updated if SMP is deleted or updated.  For deletion or update of records in the DNS the more controlled methods from ManageParticipantIdentifier must be used:

    • To delete SMP with participant count larger then max allowed count, the participants must be deleted first using ManageParticipantIdentifier.Delete or ManageParticipantIdentifier.DeleteList and then SMP can be deleted.

    • To update SMP logical address with participant count larger then max allowed count, the new SMP entry with new logical address must be created  and participants must be migrated to new SMP

Supported platforms:

  • Application servers:
    • Apache Tomcat 8.5
    • WebLogic 12.2.1.3
  • Database:
    • MySQL 5.7 (tested version, future versions might work)
    • Oracle 11 XE and Oracle 12c 
  • Java:
    • Oracle JDK 8 for WebLogic 12.2.1.3
    • OpenJDK 8 for Tomcat 8.5


Support for multivalued RDN certificates for authentication to SML

Migration from 4.0.1 to 4.0.2
