Tutorial

(1) Workflow submission

(1.1)If you already have an existing workflow, you can just paste it into the input area and click button “WS Workflow Submission”.

(1.2)If you just want to get familiar with the user interface and content of workflow does not matter, you can click button “click to see example” and you will see a pop-up window which contains a sample window. Then you can copy it and paste it into the input area. Now, you can submit it. The pop-up window will be hidden if you press “Esc” key or if you click anywhere else which results in that the pop-up window loses focus.

After workflow is submitted, response from server is displayed in the area labeled as “Response from server”.

Note: response is appended to the content of the output area. So if you want to discard the existing response, you should clear it first by clicking button “clear”.

Sample response is:
-------------------------------------------------
(This is done by using web service with status monitoring enabled)
ID for the workflow you just submitted is:
test_79
You can use it as a handle to check its status.
As you see, the workflow id for the workflow you just submitted is returned. And then you can check its status.

(2) Workflow status query

(2.1) If you want to query status of all submitted workflows belonging to your, just click button “Get State of All Workflows”.

(2.2) If you want to query status of specified workflows, you should input ids of the workflows status of which you want to query. Then click button “Get State of A Workflow”. Note: name of the button is kind of misleading. Actually, more than one workflow can be queried every time. Multiple workflow ids should be separated by line feed, blank space and tab.

Note: response is appended to the content of the output area. So if you want to discard the existing response, you should clear it first by clicking button “clear”.

(3) Workflow composition

When the widget toolbox is expanded, it looks like:

When you move cursor over a certain element in the panel, a pop-up window is displayed to show brief description of that element. When you move cursor out of the element, that pop-up window disappears.

If you want to insert an element into the workflow, just click the corresponding element in the toolbox panel. If that element does not have parameter, corresponding xml snippet is directly inserted into the workflow. If the element has attributes which need to be set, a window will be popped up. For element “execute”, the pop-up window looks like this:

You can specify values of various attributes and insert it into workflow by clicking button “Save”. You don’t need to specify values of all attributes. In other words, you just need to set values of those attributes you need.

The xml snippet is not simply appended to existing content of the input area. Instead it is inserted into current caret position in the input area. Moreover, the xml snippet can be inserted to enclose your selected text.
