Accessing Google Search Web Service and displaying the search result

Java Studio Creator is bundled with a very powerful data handling layer between the components and the underlying data. Data Provider allows the users to access data in a consistent way, even though the data may come from different sources such as Database, EJB or a Web Service. In this blog I want to show how to use Data Provider to connect to Google Search Web Service to fetch data and display it in a table with proper link to web sites. Every thing is done graphically except for 2 line of code user needs to write in the Java file. Yes, just 2 line - it is not a typo!

This is what you need to do after creating a creating a project in Creator 2. Lets call the project GoogleSearch.

Adding components

Add a Text Field
Add a button (text - Google Search)
Add a Table component

Adding Web Service

Drag and Drop
    Servers -> Web Services -> samples -> GoogleSearch -> doGoogleSearch
    (This adds W/S client googleSearchClient1 & MethodResultTableDataProvider
      googleSearchDoGoogleSearch1)
Select googleSearchDoGoogleSearch1 in the out line and modify in the property sheet
      key - <your Google search key> (Note: You need to register and get a
                key at http://www.google.com/apis)
      maxResults = 10
      q - Sun Java Studio Creator (Initial search, you can change it
      later in the text field)

Adding Data Provider

Drag and Drop an Object Array Data Provider. (id - resultArrayDataProvider)
Add an indexed property called "resultArray" of type webservice.googlesearchservice.ResultElement[]
Select resultArrayDataProvider and set its array property to "resultArray"

Setting Data Provider to Table

Right click on table and select Table layout and then select Data Provider resultArrayDataProvider
Remove all columns except URL, snippet, summary and title
Select HyperLink for component type for the column URL
In the Outline Select tableColumn1 -> hyperlink and click [...] for the "url" property in the property sheet
Deselect "escapt" property of tableColumn2 -> staticText1, tableColumn3 -> staticText2, tableColumn3 -> staticText2

Setting Text Field Value to googleSearchDoGoogleSearch1

Right click on TextField and select property binding and set the binding to googleSearchDoGoogleSearch1
(The text should be - Sun Java Studio Creator)

Setting the Search Result to resultArrayDataProvider

Double click on "Google Search" button and add code

 resultArray = (ResultElement[]) ((GoogleSearchResult) getGoogleSearchDoGoogleSearch1()
               .getResultObject()).getResultElements();
 resultArrayDataProvider.setArray(resultArray);

Deploy and see the result after clicking on the "Google Search" button.
