This WP8 Activity Report described the activities performed in September 2012 by Beneficiary and Task.

It is part of the Monthly Activity Report.

T8.1 iMarine Data e-Infrastructure Enabling-technology Development

CNR Activities

After the deviation reported on M10, CNR resumed and finalized the work on Resource Manager 2.0 (RM2). The service has passed a comprehensive testing phase. Integration with its clients also provided valuable feedback and raised some minor issues that were fixed along. A new feature has been added upon request of VREModeler service: a timer for managing long sessions. This avoids partial reports from RM2 and a more accurate reporting to clients. Sessions now report which node(s) did not respond on time, whose packages were expected to be deployed there and possible causes. Thus, RM2 has been released as part of gCube 2.10.0.

As support to RM2's client, CNR also supervised the implementation of the new Deployment/Undeployment Tests to be executed by WP7 on gCube 2.10.

The VREModeler Service has been modified to be functionality-oriented and for the integration of the new ResourceManager stubs (2.0.0).


None to report


  • resource-manager-service 2.0.0 release
  • vremodeler-service and stubs 2.0.0 release
  • deployer-service and stubs 2.4.0 release
  • wiki dev guide of resource manager updated

FAO Activities

FAO has overseen to the release of gCore 1.5 and common-scope 1.0 in gCube 2.10, solving a performance issue with the latter that emerged during integration builds as failed tests. It has accordingly changed the process for the discovery of the ScopeProvider implementation to replace extensive classpath scanning techniques with standard ServiceLoader mechanisms.

FAO has also released maven-service-plugin 1.1.0 in gcube-externals (outside the release of gCube), which now supports the generation of full GAR artefacts for manual deployment. This was performed as a basic step towards simplified installation of enabling services in testing and production infrastructures. FAO has participated to a number of discussions with ENG, CNR, and CERN on the mavenization of the gHN distribution and on dependency versioning at large, proposing a solution based on Maven's Bill-Of-Materials (BOMs) which CERN/CNR are currently implementing.


None to report.


  • maven-service-plugin 1.1.0 release

T8.2 iMarine Data e-Infrastructure Policy-oriented Security Facilities

E-IIS Activities

In September ENG has been involved in the following activities:

  • implementation GCube Security Handler: in order complete this activity, several clients implementing SAML Enhanced Client or Proxy profile have been tested. The implementation is currently in advanced status.
  • presentation of SOA3 at the EGI technical Forum in Prague


  • A slight delay in the implementation of GCube Security Handler that should be ready just after the TCOM

T8.3 Workflow Management Facilities

NKUA Activities

Last month, NKUA focused on the integration with the minor release of gCube 2.10. Work has been done on the transition of three library components from ant to maven. The adaptor of the search system was ported from java logger to slf4j. Also, bug fixing and extensive testing took place.
