Google Drive API Example - What worked for me

-

An interesting Java example exists for the Google Drive API on the Google Developers Site. It is located in the Quick Start menu.

It is intended to provide developers with a simple way to start using the Google Drive API.

While this is a welcome extension provided by Google, I ran into problems making this example work.

The first problem I encountered was enabling the Drive API.


The instructions indicated that you are required to "enable the Drive API". I did this, but it appears you also need to enable the Drive SDK as well. If you fail to enable both you receive an "access not configured" error.

The 2nd problem that caused me a few hours of frustration was the inability to build the example using the suggested Maven configuration.

After numerous attempts I was able to settle on this Maven configuration which appeared to work.

<dependency>
      <groupId>com.google.apis</groupId>
      <artifactId>google-api-services-drive</artifactId>
      <version>v2-rev66-1.13.2-beta</version>
    </dependency>
    <dependency>
      <groupId>com.google.http-client</groupId>
      <artifactId>google-http-client-jackson2</artifactId>
      <version>1.14.1-beta</version>
    </dependency>

I agree this looks like a "hack". ( I am using different versions of the google library ). The problem I encountered was that the example was using a class from a Java package ( com.google.api.client.json.jackson2.JacksonFactory ) which I could only find in the com.google.http-client library.

I suspect there is a better approach, if so, I would be interested to know.

Or, maybe Google can update their documentation....

Vaadin - GRID Component

Introduction Vaadin 7.4 was recently released and it includes a new component called the GRID . It represents a 'Spreadsheet" type model from a UI perspective, however I think it lacks a lot of features you would expect from this type of component. Maybe this component will evolve over time and it will begin to have the functions that you expect from a spreadsheet. ( note: there is a commercial add on called the Spreadsheet from Vaadin ) Use Case The use case I am demonstrating below is a simple grid showing projected sales of Widgets over a five year period. Creation Creating a Grid is very simple and you have numerous options for sizing on the page. In the example below I setting it across the page. The Grid rows can be selected for editing, you can select single or multiple rows in a single action. myGrid = new Grid(); myGrid.setSizeFull(); myGrid.setSelectionMode(SelectionMode.SINGLE); Container Backing Similar to many other Vaadin componen...

Connecting a Vaadin SQL Container to a Combo Box

-
It must be me. But I spent a lot of time trying to figure out how to connect a database table implemented as a Vaadin SQL Container to a Vaadin Combo Box. It seems such a simple concept. Anyway, here was my requirement. I needed a combo box to contain a list of Australia suburbs. The user would select a suburb which would filter the results in a table on the screen. My database table was very simple. A id field ( which was the primary key ) and a name field which contained the suburb name. The code for the SQL Container was simple. TableQuery q = new TableQuery("suburb", connectionPool); suburbContainer = new SQLContainer(q); Now code to establish the combo box and links to the SQL Container.   ComboBox suburbCB = new ComboBox();  suburbCB.addItem("");  suburbCB.setCaption("Filter by Suburb");  suburbCB.setContainerDataSource(app.getDatabase().loadSuburbs());  suburbCB.setItemCaptionPropertyId("name");  suburbCB.setItemC...

Vaadin and Google Maps

-
Vaadin and a Google Map Widget One of my major irritations with Vaadin has been its lack of support for Google Maps as a standard widget. The reality is that many commercial applications require some form of mapping feature and the lack of support for a standard Google Map widget has been a major problem. However this has changed with Version 7.x of Vaadin, a new Google Map Addon has appeared and it fills a very important gap in the Vaadin feature set. How to Use It. If you use Maven in your development process then using the Addon in your Vaadin project is very easy. Just place this dependency in your POM file and make sure you have the correct repository established for the Vaadin Add On's. <dependency>    <groupId>com.vaadin.tapio</groupId>    <artifactId>googlemaps</artifactId>    <version>0.6.2</version> </dependency> Here is some simple code to get you started. It creates a Googl...
