Hello,

In my program I integrated Taverna for the execution of workflows without Gui. By updating the classes from Taverna 1.4 to Taverna 1.5.1 I couldn't find the freefluo classes (uk.ac.soton.itinnovation.freefluo.util.xml.XmlUtils). But I found a WorkflowLauncher class in the JavaDoc, which enables executing a workflow without the gui. I tried to use the WorkflowLauncher too, but couldn't find the execute method in 1.5.1. Only a main method, which returns no result. So my question is, how can I easily execute a workflow without using the gui and get a Map in return?

Here is an abstract of my former code:

String workflow = "RPSBlastWorkflowWithParameters.xml"; ScuflModel model = null; EnactorProxy proxy = null;

File workflowXmlFile = new File(workflow); Document jdomDoc;

jdomDoc = XmlUtils.jdomDocumentFromFile(workflowXmlFile);

// create a ScuflModel model = new ScuflModel();

// populate the workflowXml as jdomDoc, the model XScuflParser.populate(jdomDoc, model, null);

// connect to the webservice proxy = FreefluoEnactorProxy.getInstance();

Map inputs = new HashMap(); inputs.put("sequence",DataThingFactory.bake(query.getSequence().toUpperCase())); inputs.put("length", DataThingFactory.bake(new Integer(query.getLength()).toString())); // iterate over all parameters and add each parameter to input Set params = parameters.keySet(); Iterator itparam = params.iterator(); while (itparam.hasNext()) { String key = itparam.next().toString(); inputs.put(key, DataThingFactory.bake(parameters.get(key) .toString())); }

// create a instance of workflowInstance WorkflowInstance workflow = null;

try{ workflow = proxy.compileWorkflow(model, inputs, null); } catch(Exception e){ e.printStackTrace(); } workflow.run(); Map outputs = workflow.getOutput();

Thanks in advance! Best regards, Anika
