Taverna Workbench 2.2.0
=======================
The Taverna team are pleased to announce that Taverna workbench 2.2.0
and command line tool are now available for users to download from
<http://www.taverna.org.uk/download/workbench/>
Taverna 2.2.0 includes improvements to the workbench user interface and
gives users greater control over the workflow engine. Here are a few of
the new features in the workbench:
* Loading and sharing of service sets
* Ability to load and edit workflows that contain services that are
offline
* Reporting on the state of the workflow
* Tabular representation of a workflow run
* Retrying and parallelization of service calls
* Consistent representation of the intermediate and workflow results
* Pause/resume/cancel of a running workflow
Taverna 2.2.0 also includes a command line tool that allows you to
execute workflows outside of the workbench. The command line tool is
available either bundled with the workbench or as a separate download
from <http://www.taverna.org.uk/download/command-line-tool/>
Tutorials and examples
======================
Tutorials for Taverna are available on the Taverna website
<http://www.taverna.org.uk/documentation/taverna-2-x/tutorials>.
Example workflows can be found under the Starter pack tab in the
myExperiment section of the workbench. They can also be downloaded from
the myExperiment website <http://www.myexperiment.org/packs/122>
Known issues
============
Although Taverna 2.2.0 contains many improvements there are some known
issues with it. These are detailed in known-issues.txt in the download.
An updated and more detailed list can be found in our issue tracker Jira
<http://www.mygrid.org.uk/dev/issues/secure/IssueNavigator.jspa?mode=hide&requestId=10171>.
Taverna and Java
================
Taverna requires the Java Runtime Environment (JRE) version 5 or 6 from
Sun. No other versions of Java have been tested. You can download Java
from Sun <http://www.java.com/getjava/>.
Java on Linux
-------------
Some Operating Systems, such as Ubuntu, come with the Gnu GCJ version of
Java that cannot be used to run Taverna due to bugs in GCJ.
To download Sun Java 6 for Ubuntu
<https://help.ubuntu.com/community/Java>, start a Terminal and type the
following:
sudo apt-get install sun-java6-jre
and follow the instructions. You might also have to switch the default
Java installation by running something
like
sudo update-java-alternatives -s java-6-sun

particular how to set the location of the Graphviz binary dot if needed.
