Taverna 2.2 starter pack
<p>The Taverna team are pleased to announce that Taverna 2.2.0 workbench and command line tool are now available for users to <a href="http://www.taverna.org.uk/download/workbench/">download</a>.<br />
<br />
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:<br />
<br />
* Loading and sharing of service sets<br />
* Ability to load and edit workflows that contain services that are offline<br />
* Reporting on the state of the workflow<br />
* Tabular representation of a workflow run<br />
* Retrying and parallelization of service calls <br />
* Consistent representation of the intermediate and workflow results<br />
* Pause/resume/cancel of a running workflow<br />
<br />
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.<br />
<br />
<b>Tutorials and examples</b><br />

<b>Known issues</b><br />
<br />
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.

<br />
<b>Taverna and Java</b><br />
<br />
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 <a href="http://www.java.com/getjava/">Sun</a>.<br />
<br />
<b>Java on Linux</b><br />
<br />
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. <br />
<br />
To download Sun Java 6 for <a href="https://help.ubuntu.com/community/Java">Ubuntu</a>, start a Terminal and type the following:<br />
<br />
<i>sudo apt-get install sun-java6-jre</i><br />
<br />
and follow the instructions. You might also have to switch the default Java installation by running something like</p>
<p> <i>sudo update-java-alternatives -s java-6-sun</i><br />
