7) that simple web service works well in Taverna 1.7 (xml splitters are still
needed though, but it works)
8) I doubt my graphviz does not work well with Taverna 2.0 since I cannot even
add an workflow output - nothing happens when I click, right click, or double
click 'output' from the list on the right panel to add a workflow output.

Thanks for the hints Mahmut, I tried to use Netbean with a simple web service -
it was tested and worked in browsers.
I am still having troubles cooperating that web service into Taverna 2.0
1) The simple web service was created by following
http://www.netbeans.org/kb/docs/websvc/jax-ws.html#Exercise_1
@WebService()
public class CalculatorWS {
/**
* Web service operation
*/
@WebMethod(operationName = "add")
public int add(@WebParam(name = "i") int i,
@WebParam(name = "j") int j) {
int k = i + j;
return k;
}
}
2) I was able to add
http://localhost:8080/CalculatorWSApplication/CalculatorWS?wsdl into Taverna as
a WSDL activity
3) I had to use XML splitters for both input and output (I wonder if this has
to be done in this way)
4) the splitter for the input exposes 2 input parameters correctly, i and j
respectively. (they are both integers )
5) but seems no way that I can give i and j initial values, double click, right
click, or left click from the splitter did not do anything.
6) and the console gives the following errors:
Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: For
input string: "71.78"
at
java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)

I really appreciate if you can help me on that.
