2. Obtaining and Installing Software

To download this release, go to the 5.0.1 Download page.

For information on installing this release, go to the 5.0.1 Installation Guide.

2.1. Java Client API Download

GT 5.0 does not include any of the CoG JGlobus Java APIs that were included in the GT4 release series.   But, the JGlobus APIs can still be used with the GT5 services.  You can get them directly from the CoG JGlobus releases; see the following link:

http://dev.globus.org/wiki/CoG_jglobus

Consider the following when determining which version of CoG JGlobus to use:

  • The GRAM development team used CoG JGlobus version 1.6.0 for performance testing.

  • The BIRN project used CoG JGlobus version 1.6.0 (plus patches) for GridFTP testing. All patches are included in 1.8.0.

  • At the time of the GT 5.0.1 release, 1.8.0 was the recommended version.  In general, the latest recommended CoG JGlobus version should be used.
