How to Attach Java Source Code in Eclipse

Here is the simple way how to Attach Java Source Code in Eclipse:

WAY 1

1. Go to the page where this source is located (in my case it was not something like src.zip or FILE, but whole FOLDER with everything you need): http://download.java.net/openjdk/jdk6/ This is how this page it looks like http://nekaka.com/d/quyFnl0ynC

2. Download archive with the name "openjdk-6-src-b25-01_may_2012.tar.gz" (as an example). 

Or download it directly from this link: http://nekaka.com/d/92tCNq5nhN (I hope it is still there).

3. Again (this is important) when you will unpack this archive you will not find any src.zip, all you need is this very FOLDER with same name openjdk-6-src-b25-01_may_2012.

4. Now this is what you need to do in Eclipse - press the button "Attach Source", here is like it looks like http://cavdar.net/uploads/2008/07/method1.gif and... THIS IS VERY IMPORTANT (this super hint costs many hours) choose EXTERNAL FOLDER (NOT FILE) pointing to the unpacked folder with the source code openjdk-6-src-b25-01_may_2012.

5. Press OK and that's it. Once again: don't look for the magic file SRC.ZIP

WAY 2

1. Do everything as it is in WAY 1, but instead of selecting openjdk-6-src-b25-01_may_2012 folder do select sources from Android SDK folder:

Java Collection Set to Array

If you want to change your Set implementation to Array this is the way you can make it:

Set<String> set = new HashSet<String>();
String[] array = set.toArray(new String[set.size()]);

Android: How to refer to the current activity inside of a listener.

Instead of this use YourActivityName.this where YourActivityName is the class name of your Activity subclass.

Explanation: You are creating an anonymous inner class when you use this part of your code: "new OnClickListener() {". Anonymous inner classes have a reference to the instance of the class they are created in. It looks like you are creating it inside an Activity subclass because findViewById is an Activity method. Activity's are a Context, so all you need to do is use the reference to it that you have automatically.

Refer to this link for more explanation.

How to run GWT test with Maven

If you want to run just one test do this:

1. Go to the module where your tests live. In my case it is here:

MBPro-2:ui-common apple$ pwd
/Users/apple/Documents/workspace/svn/TRT-1##9/t0-mvn/ui-common
MBPro-2:ui-common apple$ 


2. Then run the test
mvn -Dtest=HostlistExprTestGWT test

HostlistExprTestGWT is the name of the test without its extension.

Java and Python password generators resources

Python password generator code:

import random, string

myrg = random.SystemRandom()

length = 10

alphabet = string.letters[0:52] + string.digits

pw = str().join(myrg.choice(alphabet) for _ in range(length))

print pw

Java password generator resource:

http://ostermiller.org/utils/RandPass.html

import java.security.SecureRandom;

import com.Ostermiller.util.RandPass;

public class PasswordGenerater {

public static void main(String[] args) {

SecureRandom sr = new SecureRandom();
