As we continue to evolve the GT documentation, we've added some new features since 4.2.0:
WS Authentication and Authorization in C manuals are now available.
Java WS Core includes informatin on a new reference for WSRF-JPA.
Each guide is now displayed on one page (with a few exceptions where the page would be too long). This allows for easier searching and printing to find the info you need.
GT Commands Reference - All GT clients in one reference. A PDF version is also available.
Feel free to offer any suggestions or feedback using Bugzilla (the "Documentation" component). Or use the documentation feedback box at the bottom of each page (please note that this box is intended for feedback and suggestions, but not support - support information follows.)
