I'm doing common build implementation based on Ant 1.8 Ivy 2.2 and Nexus current status can be found here

By default IBM Websphere Portal 6.0 uses the following chain to determine user locale

Navigation State
User Profile
Accept-Language

So when navigation state is lost there is a problem if we want to show content in a locale different from User Profile.
For instance when using url mapping the state is lost

on this image if we change the language and click 'Certificate Managment' language will be taken from User profile not from current settings since navigation state will be lost.

We can implement our own approach by writing a filter for wps.war which will use cookie with selected language.

New Chain to determent User locale

User open portal browser default language is used . User selected different language-cookie is set with this language. New language is used.

1. Set cookie when a User selects language

wps.ear\wps.war\themes\html\theme\Default.jsp - page contains the language selection logic insert logic to set cookie when the user selects the language

 
<script type="text/javascript">
dojo.addOnLoad(function(){
dojo.require("dojo.cookie");
 dojo.query("a.change-language",dojo.byId("languagePart")).forEach(function(el){
 	dojo.connect(el,"onclick",function(_event){
	  _event.preventDefault();
	  _event.stopPropagation();
	  var loc=dojo.trim(el.innerHTML)==='ENG'?'en':'ru';
	  dojo.cookie("selectedUserLocale",loc,{path:"/"});
	  window.location=el.href;
	});
			
 });

	
});
</script> 

......
      <a  href='<portal-navigation:url command="ChangeLanguage" commandParam="en"/>'
                                class='<%=styleAEn%> change-language'> ENG
					           </a> 

......

2. Create Filter with Request Wrapper

LocaleRequestWrapper

public class LocaleRequestWrapper extends HttpServletRequestWrapper implements IServletRequest {
	private String locale = null;
	private Locale localeObj;
	private List locales = new ArrayList(1);

	public LocaleRequestWrapper(HttpServletRequest request) {
		super(request);

		String selectedLocale = getLocaleFromCookie(request.getCookies());
		String langCode = selectedLocale != null ? selectedLocale : request.getLocale().getLanguage();

		if (langCode != null && langCode.trim().length() > 0) {
			this.locale = langCode;
			localeObj = new Locale(langCode);
		}

		if (locale != null) {
			locales.add(locale);
		}
	}
	
	private String getLocaleFromCookie(Cookie[] cookies) {
		if(cookies==null)
			return null;
		for (int i = 0; i < cookies.length; i++) {
			Cookie c=cookies[i];	
			if(!"selectedUserLocale".equals(c.getName()))
				continue;
			return c.getValue();
		}
		return null;
	}
	

	public Object clone() throws CloneNotSupportedException {
		LocaleRequestWrapper crequest = (LocaleRequestWrapper) super.clone();
		javax.servlet.ServletRequest inner = crequest.getRequest();
		if (inner instanceof IServletRequest)
			crequest.setRequest((HttpServletRequest) ((IServletRequest) inner).clone());
		else
			throw new CloneNotSupportedException();
		return crequest;
	}

	public String getHeader(String key) {
		// get the original request
		HttpServletRequest request = (HttpServletRequest) getRequest();
		// if the header request is for locale, return the stored locale
		if (!"Accept-Language".equalsIgnoreCase(key))
			return request.getHeader(key);
		return locale != null ? locale : request.getHeader(key);

	}

	public Enumeration getHeaders(String key) {
		// get the original request
		HttpServletRequest request = (HttpServletRequest) getRequest();

		// if the header request is for locale, return the stored locale
		if (!"Accept-Language".equalsIgnoreCase(key))
			return request.getHeaders(key);
		return locale != null ? Collections.enumeration(locales) : request.getHeaders(key);

	}
	
	public Locale getLocale() {
	  return localeObj != null ? localeObj:((HttpServletRequest)getRequest()).getLocale();	  
	}

	public Enumeration getLocales() {
	  return locale != null ? Collections.enumeration(locales) :((HttpServletRequest)getRequest()).getLocales();	  
	}
}

LocaleServletFilter

public class LocaleServletFilter implements Filter{	  
	public void doFilter(	ServletRequest request,  
							ServletResponse response,
							FilterChain chain) throws IOException, 
												ServletException {
	    LocaleRequestWrapper wrapper = 
	    			new LocaleRequestWrapper((HttpServletRequest)request);
	    if (chain != null)
	      chain.doFilter(wrapper, response);
	  }

	public void destroy() {

		
	}

	public void init(FilterConfig arg0) throws ServletException {
	
		
	}
}

3. Add filter mapping

<filter>
   <filter-name>Locale Filter</filter-name>
   <filter-class>...LocaleServletFilter</filter-class>
</filter>

<filter-mapping>
       <filter-name>Locale Filter</filter-name>
	<url-pattern>/myportal/*</url-pattern>
</filter-mapping>
<filter-mapping>
       <filter-name>Locale Filter</filter-name>
       <url-pattern>/portal/*</url-pattern>
</filter-mapping>

4. Remove from Portal\wmm\wmmLDAPServerAttributes.xml preferredLanguage attributeMap

to prevent portal looking the locale in the user profile

Developing a multi-locale site using WebSphere Portal V5.1.0.1

Idea has been taken from this article.

The main idea is to restrict user to use only one session. For example if user logged in in one browser and then logged in in another one this restriction prevent users's work in the first browser.
Based on this article Restricting Multiple Sessions in WebSphere Portal I've created the session restriction implementation . It would be good to go through Restricting Multiple Sessions in WebSphere Portal article first and then read this implementation.

1. DB schema

CREATE TABLE "DB2ADMIN"."LOGINUSERDATA"  (
		  "CUSTOMERID" VARCHAR(100) NOT NULL , 
		  "SESSIONID" VARCHAR(300) NOT NULL , 
		  "NODEIP" VARGRAPHIC(100) NOT NULL , 
		  "TIMESTAMP" TIMESTAMP NOT NULL )   
		 IN "USERSPACE1" ; 


ALTER TABLE "DB2ADMIN"."LOGINUSERDATA" 
	ADD CONSTRAINT "CC1277458314344" PRIMARY KEY
		("CUSTOMERID");

2. Custom login module

to be able to monitor user login data custom login module should be created
the main goal of this class is to write user data into DB and into cache. This implementation uses DynaCache to cache user data

public class LoginUserAuth extends com.ibm.wps.engine.commands.LoginUserAuth {
	
	private LoginUserService loginUserService= LoginUserService.INSTANCE; 
	private static final Logger logger = Logger.getLogger(LoginUserAuth.class);
	
	protected void doPostLogin(RunData aRunData, String aUserID, String aPassword) throws WpsException {
		if(aUserID==null)
			return;		
		loginUserService.saveUser(new LoginUserData(aUserID,aRunData.getSession().getId()));
	}

		
}

in WebSphere AS the following changes should be done

in WP LoaderService Custom properties is added command.path with value com.minosiants.auth.cmd,com.ibm.wps.engine.commands, com.ibm.wps.dynamicui.commands

3. Portal filter

To be able to prevent usage of "old session" each request now should be checked if its session ls up to date. If it is not request should be redirected to logout page.

public void doFilter(ServletRequest request, ServletResponse response , FilterChain chain) throws IOException, ServletException {
				
	HttpServletRequest req = (HttpServletRequest)request;
	HttpServletResponse resp = (HttpServletResponse)response;
	String userId=req.getRemoteUser();
	if(userId==null){
		chain.doFilter( request, response );
	}			
	if("wpsadmin".equals(userId)){
		chain.doFilter( request, response );
		return;
	}
	String logoutURL=generateLogoutURL(req,(HttpServletResponse)response);		
	if(!loginUserService.isCurrientSession(userId, req.getRequestedSessionId())){			
		try {
			String url=ServletURLHelper.generateUrl("CUSTOM_LOGOUT", null, null, req, resp);				
			request.setAttribute("logoutURL", logoutURL);				
			if(!req.getRequestURI().toString().equals("/wps/portal")){						
				url=url.replaceAll("/wps/", "/");
				filterConfig.getServletContext().getRequestDispatcher(url).forward(request, response);
				return;
			}				
				
		} catch (StateException e) {
		
			e.printStackTrace();
		} catch (NamingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		chain.doFilter( request, response );
		return;
	}
			
		chain.doFilter( request, response );	     
		
}

this filter should be added into wps.war web.xml
IBM\WebSphere\profiles\wp_profile\installedApps\NAME\wps.ear\wps.war\WEB-INF\web.xml
and
IBM\WebSphere\profiles\wp_profile\config\cells\GSRUE\applications\wps.ear\deployments\wps\wps.war\WEB-INF\web.xml

....
<filter>
 <filter-name>UserSession</filter-name>
 <filter-class>com.minosiants.auth.filter.UserSessionFilter</filter-class>
</filter>
....
<filter-mapping>
 <filter-name>UserSession</filter-name>
 <url-pattern>/*</url-pattern>
</filter-mapping>
....

4. Custom logout portlet

To make logout process more user friendly new portlet should be added. This portlet contains only view on jsp page.
And this portlet is placed on a portal page. CUSTOM_LOGOUT unique id is assigned to this page

<script type="text/javascript">

  dojo.addOnLoad(function(){
	var myTimer = new dojox.timing.Timer();
	myTimer.setInterval(1000);
	myTimer.onTick = function () {
	  	var sec=15;				
		return function(){						
			sec=sec-1;
			dojo.byId("sec").innerHTML=sec;
			if(sec===0)
				window.location="/wps/portal";
			};		        
	}();
	myTimer.start();
	
	var b=dojo.byId("goButton");	
	dojo.connect(b, "onclick", function(event) {                               
	    console.log("click");
	    event.preventDefault();
	    event.stopPropagation();

portlet for logout view

Default approach used in IBM portlet application for integration resource bundles into view parts is really ugly.

So I've created another taglib which contains one tag placeResourceBundleData
This tag places an attribute java.util.Map under name ui into ServletRequest and places the same map converted into javascript object under var ui .
Now all properties from the resource bundle available during jsp translation and on the client side in javascript.
Changes in the bundle dont require restart of the application and available on the fly.

OnePortletResource_en.properties

firstPage.my.title=placeResourceBundleData portal tag demo
firstPage.message.hello=Hello
firstPage.message.world=World

index.jsp

<%@taglib uri="http://minosiants.com/tl/core" prefix="pc"%>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title></title>

<script src="http://o.aolcdn.com/dojo/1.4/dojo/dojo.xd.js"
        type="text/javascript">
</script>
<script type="text/javascript">  
    dojo.addOnLoad(function(){             
     <pc:placeResourceBundleData bundle="com.minosiants.nl.OnePortletResource" />				
      var msg=ui.firstPage.message;
      dojo.byId("h1").innerHTML=msg.hello+" "+msg.world;
    });          
</script>
</head>
<body>
	<h1>${ui.firstPage.my.title}</h1>

I've created test web project to demonstrate how it works TestTaglib.zip

Finished reading this book(Amazon) written by Robert Hoekman, Jr and Jared M. Spool. Although it seems too long , its good. I've created Web Anatomy MindMap of it.

BusinessObjects Components

CRYSTAL REPORTS SERVER XI RELEASE 2
BusinessObjects Portal Integration Kits

General Architecture

Three components participate. BusinessObjects Portlets , Crystal Reports Server, InfoView BusinessObjects Web application - UI working with Crystal Reports Server. JAAS SSO and Ldap are used for the SSO.
Poertlets and InfoView installed on the same Websphere but on different servers.
The whole installation process is written in BusinessObjects documentation. So instead of repeating it I just post the links

BusinessObjects Enterprise XI R2 PortalIntegration Kit Installation Guide for IBM WebSphere

JAAS SSO Enablement Extensions Deployment Guide for IBM WebSphere

Document List Portlet

There were two problems

Description

Document list contains list of the reports from crystal server. Each report is a link to InfoView which is responsible to open a report itself. When Document list opens - new portlet session is created and this session is alive unless any report is opened or portlet session timeout comes. It happens because InfoView also create a session. Both these session store session id a cookie JSESSIONID overwriting the previous value. Creation of any of these sessions assumes login into Crystal Report Server which means a new licence usage. With the restricted number of licences and active work at the portal and with the reports after a while we run out of the licences and unable to work further.

Solution

Session cookie name of deployed InfoView should be changed from its default value

Description

Accessing after a while of not using Document list portlet there is a some kind of timeout exception.

Solution

Remove timeout of the session in the deployed document list ear

Increase value of BusinessObjects Enterprise Token Timeout in deployed document list ear

<context-param>
<param-name>BusinessObjects Enterprise Token Timeout</param-name>
<param-value>300</param-value>
</context-param>

Секреты мотивации персонала by @ForbesRussia via @splix

интервью с 
Сергем Белоусовым

А третья мотивация — талантливые люди хотят развиваться, заниматься самоулучшением. Хотят видеть не только повышение денежной компенсации за свой труд и карьерный рост, но и повышение собственной квалификации. Например, создание программного продукта — это командная игра, где участвуют, скажем, 100 человек. Эти люди между собой сложным образом взаимодействуют, они быстро собирают головоломку, которая потом становится продуктом и продается. Люди обучаются лучше играть в эту игру, и им это нравится.

30 predictions for the future of twitter

Some interesting quotes to remember

Promos by brands and retailers will have big success 
for last minute deals

Talking to shops and restaurants via Twitter will become standard
and will get opt in coupons as we enter a shop, based on location

Interesting in a restaurant|shop based on my location I'd be able to start talking and getting coupons. (this should be exposed later )

There will be more devices publishing updates than humans
wifi scale, planes, trains, cars all posting updates.

remotely control the house by the status update

thats good

3. The era of social colonization -
For consumers, surfing the Web is no longer a lonely experience. Forrester foresees the release of new browsers and frictionless, uncomplicated technologies that allow people to truly surf the Web with friends or see what they're doing in real-time.

it'd be nice to be in a colony of people with the same interest but in the same time I think it would narrow my view and bring the filling that nothing else exist . The most interesting thing would be at the intersection of different colonies . I't be nice to have a button "Go to completely different colony" LOL

Perhaps the future lies with making data mobile while still providing value to the economics of social networks. DataPortability.org is working with some of the most renowned networks to enable users to bring their identity, friends, conversations, files and histories with them, without having to manually add them to each new service

It used to be blog where people store log of their life activity. Now it mostly social platform. Regarding to that almost everything is cyclic, probably mobile data would become Blog 3.0.

Мтс предлагает тариф МТС Коннект c без лимитным интернетом

Максимальная скорость передачи данных при подключении услуги «Бюджетный безлимит» составляет 128 Кбит/сек, абонентская плата - 349 рублей в месяц. При подключении услуги «Безлимитный онлайн» максимальная скорость ограничивается 512 Кбит/сек и абонентская плата составляет - 549 рублей в месяц.

Проблема в том что стоимость исходящих вызовов на тарифе с безлимиитным интернетом 3 - 3,5 руб.
Но можно установить Sipdroid - это SIP клиент и пользоваться VoIP вместо GSM звонков.
В моем случае я установил sipdroid и использую voipcheap и получается теперь

звонки на обычный телефон по Питеру и Москве бесплатны, по России ~ 1 руб.
звонки на мобильный по всей России ~ 1.7 руб.

Sipdroid настроил только вчера поэтому пока еще не знаю насколько стабильная эта штука , а voipcheap пользуюсь уже давно качество у них связи хорошее.

Начал пользоваться HTC Hero и мое общее настроение - нравится.
Купил на ebay вот у этого продавца. EMS идет ~ 10 дней. В Питере официально продаются только черного цвета и стоит немного дороже.

Первая не понятная вещь - наличие только английской локали (в российской версии доступны две локали русская и английская) мне казалось ,что телефон без физической клавиатуры и поэтому тут ограничений быть не должно . Например если владелец разговаривает еще на другом языке или учит иностранный язык то как тут быть ? . Оказалось что поддержка других локалей есть просто она скрыта. Для того что бы ее активировать надо модифицировать конфигурационные файлы , а для этого надо перепрошить телефон с root доступом.
Способ получения root доступа
Прошивка
Тут разные сборки альтернативных прошивок с разной кастомезацией
Способ активирования локали
После этого можно пользоваться клавиатурой с разными языками.

Другая не очень удобная вещь это импорт контактов.

Мне пришлось из старого телефона экспортировать контакты в gmail а от туда синхронизовать из на телефон. что совсем не удобно. Правда есть программа которая может импортировать их из vcard файлов прямо в hiro Import Contacts автор @bornmw.

Последние заметки

конечно такие устройства становятся очень удобными и полезными особенно с постоянным доступом в интернет.

twidroid - крутая штука

Надо еще настроить voip.
