If all is set up, lets get started..


1. Add new GAE type ‘Web Application Project’ (the one with blue google icon)

2. Copy click-2.1.0.jar and click-extras-2.1.0.jar to the lib directory under war/WEB-INF/lib of your GAE project.

3. Click on the project and select ‘Properties’ when you will modify the ‘Java Build Path’.

When changing the build path, select the two libraries you have added to you lib folder in point 2.

4. Delete the auto-generated GAE project stuff, like servlet and index.html files.
5. Create new class called ‘Index’

Note the package you choose for you newly created class file, it will be needed when modifying config files later.

6. Create click.xml file in the same location where your web.xml file exists.
7. Modify your web.xml file to look similar to the one presented below:

It looks like ordinary web.xml file with one important addition: the listener section.

8. Add content to your click.xml file:

9. Add index.htm file to the war directory

10. Deploy your app to Google App Engine and go to the url: http://yourappname.appspot.com

You should see very simple website with current time printed.

Modify your ‘index.htm’ using html editor to look something like this:

19. Start up your project in tomcat. The page should display current time!


Additional Comments:
I know that this is just a quickfix, and I just cannot belive that there is no proper eclipse plugin using the latest click framework, which would be up to date, if you know any, than please comment and save me and my readers precious time.

Thank you.

In fact you don’t have to even know object properties to generate the report, we will use Apache DynaBeans for that:

This is a simple example code snipped showing you how to get started with the simplest and most dynamic reporting library ever (as well as lacking features probably but we hope its enough for simple projects)

This example assumes the following:

1. You want simple report
2. You dont have to know the object which properties you want to display in advance, by this I mean you can create report columns dynamically, and by using apache dyna beans your objects don’t have to even exists. You just dynamically create them and inject them into the report.

Here is an example test class showing you how to use jasperberry, for more info please contact us directly at softberries.com
Code:

You should find similar snippet in a test suite of the project.
The project itself is licensed under LGPL and its available from sourceforge here

2. Prepare the application you want to make installable, I use Netbeans to build most of my Java apps, but I guess for all other ide’s the results after all are the same, we end up with SomeApp.jar file and a bunch of libraries we used to build it.
On the Netbeans platform all the files needed to launch the application we have build end up in ‘dist’ folder as a subfolder of our project main folder. If you have used any libraries to build your desktop application they will be included in the lib folder (yourproject/dist/lib/).

3. Now, once we have all the main ingredients (our application and installer) we need to connect it together. Create the folder anywhere on your machine, and call it for example ’softwarepassion’.

4. Put your jar file together with the ‘lib’ folder into the ’softwarepassion’ catalog.

5. Now we need to add some native libraries for Izpack to be able to add windows shortcuts on the desktop and start menu. Create ‘bin’ folder under the ’softwarepassion’ folder and copy whole ‘native’ content found in your izpack installation into the ‘bin’ folder of your root ’softwarepassion’ catalog.
You can find the native folder inside your IzPack installation directory, normally under: ‘C:\Program Files\IzPack\bin’

6. Create your application icon file and add it to your ’softwarepasison’ catalog. I call mine ‘exe.ico’.

7. Now comes the hardest part to get initially but after you build your first installer it all gets clear and easy
We need to prepare two separate xml files: one called ‘install.xml’ and another one called ’shortcutSpec.xml’.

The content of both example files is listed below:

And the one for windows shortcuts:

8. Example installation script contains both Readme.txt and Licence.txt which you can add to your ’softwarepassion’ folder.
9. Once you have it all in one place, you should have a structure like in the following screenshot:

10. Now assuming that your ’softwarepassion’ folder has been placed directly on the c: drive, execute the following command:

Assuming that IzPack itself was installed at: C:\Program Files\IzPack

This will produce install.jar file which is your installer.

11. If you dont’ want your end users to click on the ‘jar’ file as not everybody knows they can do that, you can add Izpack launcher app which will launch it automatically, or use another tool to create an executable called launch4j

You have to admit that it was an easy one!!!!!

Happy Installing!


Download example files from here

RowNumberTable is simple one column table displaying the ‘count’ number of rows in the second table.

In my case the ‘count’ column is called ‘Lp.’ – in polish

I have created one simple method to apply this technique to any tables in my application (I use JXTable actually but JTable will do as well)

This works of course assuming that your object index is set as first column in your model (position 0).

Step One.

Before installing anything please run the following command (actually 2 commands)

Install Java! You develop on android or not Java is a must on all my machines

You can now check your java installation by issuing two commands:

You should be able to see output stating that you have java 6 installed, huuraaayy!

Step Two.

Download and install Android SDK
You can download the latest android SDK from the android development website (developer.android.com), the link to the latest version is here
After your download completes, unzip the file to the directory of your choice. I copy the whole folder into my home directory but the doesn’t really matter.
Open up your favourite text editor (VIM of course) and add the following line at the very bottom of the .bashrc file:

Stepp Three

Download and Install Eclipse

I wish I could go for the easy one here and download the version using apt-get but unfortunately not as the version in repos is 3.2 and ADT plugin requires version 3.3 or higher. You have to download the eclipse for www.eclipse.org and unpack it. Once unpacked its ready to use!

Step Four

Download and install Eclipse plugin
This is instruction from the developer.android.com with one small modification, instead of https use http:

1. Start Eclipse, then select Help > Software Updates….
2. In the dialog that appears, click the Available Software tab.
3. Click Add Site…
4. Enter the Location:

http://dl-ssl.google.com/android/eclipse/

If you have trouble aqcuiring the plugin, try using “http” in the Location URL, instead of “https” (https is preferred for security reasons).

Click OK.
5. Back in the Available Software view, you should see the plugin listed by the URL, with “Developer Tools” nested within it. Select the checkbox next to Developer Tools and click Install…
6. On the subsequent Install window, “Android DDMS” and “Android Development Tools” should both be checked. Click Next.
7. Read and accept the license agreement, then click Finish.
8. Restart Eclipse.

After executing all the steps above you are ready for Android development. The last step in this tutorial is to run example android projects on your linux dev machine.
If you encounter an error saying :

An error occurred during provisioning.
Cannot connect to keystore.
JKS

Please check your java version. If its set to 1.5 than please run the following command:

Once you finish installing required plugins, restart your eclipse and go to Window->Preferences->Android and set up a path to your android SDK

Step Five

Check your configuration

If all went fine you can try to develop Hello World application in android. You can find the instruction on the android development site:
http://developer.android.com/guide/tutorials/hello-world.html

More android tutorials to come!
Enjoy!

public ThreeSharpWrapper(String awsAccessKeyId, String awsSecretAccessKey)

        {

            this.config = new ThreeSharpConfig();

            this.config.AwsAccessKeyID = awsAccessKeyId;

            this.config.AwsSecretAccessKey = awsSecretAccessKey;



            this.service = new ThreeSharpQuery(this.config);

        }

and then use it having the following methods:

/// Adds a bucket to an S3 account

public void AddBucket(String bucketName);



 /// Returns a string of XML, describing the contents of a bucket

public String ListBucket(String bucketName);



/// Adds a string to a bucket, as an object

public void AddStringObject(String bucketName, String keyName, String data);



/// Streams a file to a bucket as an object

public void AddFileObject(String bucketName, String keyName, String localfile);



/// Streams a file to a bucket as an object, with encryption

public void AddEncryptFileObject(String bucketName, String keyName, String localfile, String encryptionKey, String encryptionIV);



/// Gets a string object from a bucket, and returns it as a String

public String GetStringObject(String bucketName, String keyName);



/// Gets a file object from a bucket, and streams it to disk

public void GetFileObject(String bucketName, String keyName, String localfile);



/// Gets a file object from a bucket, streaming it to disk, with decryption

public void GetDecryptFileObject(String bucketName, String keyName, String localfile, String encryptionKey, String encryptionIV);



/// Copies an object from a source location to a destination location

public void CopyObject(String sourceBucketName, String sourceKey, String destinationBucketName, String destinationKey);



/// Generates a URL to access an S3 object in a bucket

public String GetUrl(String bucketName, String keyName);



/// Deletes an object from a bucket

public void DeleteObject(String bucketName, String keyName);



/// Deletes a bucket from an S3 account

public void DeleteBucket(String bucketName);



/// Changes the request payer value for the specified bucket

public String PaymentChange(String bucketName, PaymentChangeRequest.Payer payer);



/// Gets the request payer value for the specified bucket

public String PaymentGet(String bucketName);

The library is dead easy to use and most importantly it works (comparing to other S3 libraries I’ve found). Great work Joel!

Short tutorial for all offline DZone fans:

1. Install the Crocodile app found at http://crocodile.sourceforge.net
2. Run .msi installer and keep pressing next (nothing special here)
3. When you run Crocodile, click on the small cross green button to add new subscription
4. Enter ‘dzone’ in the subscription name and ‘http://feeds.dzone.com/dzone/frontpage?format=xml’ as the url address
5. Confirm by clicking ‘Ok’
6. In your subscriptions panel click ‘dzone’ and wait for your feed items to be populated.
7. Clicking on each item would display the page associated with the feed item
8. Click orange up arrow button to ‘Clean’. This will convert all links found in the feed to links pointing to original web sites submitted to Dzone
9. Now you are ready to browse the original pages submitted to Dzone by clicking on each feed item found in the list.
10. You can download the pages for offline browsing (pages are saved as .mht archives).
11. Minimizing Crocodile puts it in the system tray where it updates the feeds periodically.

Full applicaton screenshot is available from sourceforge.

Please be aware that this software has just been born and is quite messy (sometimes crashes, sometimes behaves strangely) I just wanted to share the dzone feature as quickly as I have made it and it works for me. If you want to share your time on Crocodile development please contact me either through this blog or sourcefoge web site any help would be appreciated. The Crocodile sources are available from svn repo.
