• can a webservice load jars during run time

  - by KItis

  I have created a simple web-service using Java. i want to load jars related to web-service during runtime. I have done this task for normal Java application. there what I did was JarFile jar = new JarFile(f.getPath()); final Manifest manifest = jar.getManifest(); final Attributes mattr = manifest.getMainAttributes(); // Read the manifset in jar files and get the Name attribute // whare it specified the class that need to load //for (Object a : mattr.keySet()) { for (Iterator iter = mattr.keySet().iterator(); iter.hasNext();) { Object obj = (Object)iter.next(); if ("ServiceName".equals(obj.toString())) className = mattr.getValue((Name) obj); //System.out.println(className); } /* * Create the jar class loader and use the first argument passed * in from the command line as the jar file to use. */ JarClassLoader jarLoader = new JarClassLoader(f.getPath()); /* Load the class from the jar file and resolve it. */ Class c = jarLoader.loadClass(className, true); My problem is can I put jars that need to be loaded during run time in to separate folder rather than putting in to WEBINF folder. do i have to put jars both in axis and web-application. thanks in advance for any contribution for this question.

• Sending information between JavaScript and Web Services using AJAX

  - by COB-CSU-AM

  Alright so I'm using Microsoft's Web Services and AJAX to get information from a SQL database for use with java script on the client side. And I'm wondering what the best method is. Before I started working on the project, the web services were setup to return a C# List filled with some objects. Those objects variables (ints, strings, etc.) contain the data I want to use. Of course, java script can't do much with this, to the best of my knowledge. I then modified the web service to return a 2D Array, but java script got confused, and to the best of my knowledge can't handle 2D array's returned from C#. I then tried to use a regular array, but then a found the length property of an array in JS doesn't carry over, so I couldn't preform a for loop through all the items, because there wasn't anyway of knowing how many elements there were. The only other thing I can thing of is returning a string with special char's to separate the data, but this seems way too convoluted. Any suggestions? Thanks in advance!

• Statistical analysis on large data set to be published on the web

  - by dassouki

  I have a non-computer related data logger, that collects data from the field. This data is stored as text files, and I manually lump the files together and organize them. The current format is through a csv file per year per logger. Each file is around 4,000,000 lines x 7 loggers x 5 years = a lot of data. some of the data is organized as bins item_type, item_class, item_dimension_class, and other data is more unique, such as item_weight, item_color, date_collected, and so on ... Currently, I do statistical analysis on the data using a python/numpy/matplotlib program I wrote. It works fine, but the problem is, I'm the only one who can use it, since it and the data live on my computer. I'd like to publish the data on the web using a postgres db; however, I need to find or implement a statistical tool that'll take a large postgres table, and return statistical results within an adequate time frame. I'm not familiar with python for the web; however, I'm proficient with PHP on the web side, and python on the offline side. users should be allowed to create their own histograms, data analysis. For example, a user can search for all items that are blue shipped between week x and week y, while another user can search for sort the weight distribution of all items by hour for all year long. I was thinking of creating and indexing my own statistical tools, or automate the process somehow to emulate most queries. This seemed inefficient. I'm looking forward to hearing your ideas Thanks

• java web templates across multiple WAR files

  - by Casey

  I have a multi WAR web application that was designed badly. There is a single WAR that is responsible for handling some authorization against a database and defines a standard web page using a jsp taglib. The main WAR basically checks the privileges of the user and than based on that, displays links to the context path of the other deployed WARS. Each of the other deployed WARs includes this custom tag lib. I am working on redesigning this application, and one of the nice things that I want to retain is that we have other project teams that have developed these WAR modules that "plug into" our current system to take advantage of other things we have to offer. I am not entirely sure how to handle the page templates though. I need a templating system that would be easy enough to use across multiple wars (I was thinking of jsp fragments??). I really only need to define a consistent header and main navigation section. Whatever else is displayed on the page is up to the individual web project. Any suggestions? I hope that this is clear, if not I can elaborate more.

• General web service ideas

  - by user2014175

  I have a question regarding different types of web services. I'll preface this by saying that I have built a number of apps (for both ios and android) for personal use that interact with the web via php and sql. I have taught myself these languages, and as such don't have the broader background knowledge that many of you do. My question is, in what other ways can you perform an interaction between a web service and a mobile device other than mobile - php - sql - etc. For example, If I built a very simple tracking app for my car, my current method would be to push GPS coordinates from my iphone to my database at a set interval, then I would write a simple bit of javascript that pulled those coordinates out of the database and superimposed them on a google map. Is there a different way to do this? Such as the server acting as a live middle man who simple pushed the coordinates directly to a target browser? Without the database in the middle? If so, are there advantages and disadvantages to these different methods to achieve different goals? I know its a broad question but I'm really intrigued and I'm finding it difficult to word a google search for it. Any info / reading material suggesting would be excellent. Thanks

• Migrating Ajax web application to web socket

  - by Bastan

  Hi, I think i'm just missing a little detail that is preventing me from seeing the whole picture. I have a web application which use ajax request every x time to update client with new information or tasks. I also have a long running process on the server which is a java computation engine. I would like this engine to send update to the client. I am wondering how to migrate my web app to using websocket. Probably phpwebsocket or similar. Can my server 'decide' to send information to a specific client? It seems possible looking at the php-websocket. Can my java backend long process use the websocket server to send notification to a specific client. How? well I can say that my java app could use a class that could send over websocket instead of http. But how the websocket server knows to which client to send the 'info'. I am puzzle by all this. Any document that explain this in more details? It seems that the websocket could create an instance of my web application. Thanks

• License For (Mostly) Open Source Website / Service

  - by Ryan Sullivan

  I have an interesting setup and am not sure how to license a website. I know this is not legal advice, and I am not asking for any. There are so many different Open Source Licenses and I do not have the time to read every last one to see which best fits my situation. Really, I am looking for suggestions and a nudge in the right direction. My setup is: I give away for free version of my web service with a clean website interface. The implementation I use in the actual web site is (almost) identical to what I give away. The main service works the exactly the same way, but the website interface to manage features in the service is fairly different. Really the web interfaces have the same exact backend, and the front ends accomplish the same tasks, but the service I offer on my site is very rich and uses a good deal of javascript, where I kept the interface in the version I give away as simple and javascript-less as possible. Mostly so it is easy to understand and integrate into other sites. I am not entirely sure how I should license this. It is more like I develop an open source service but have a separate site built upon it. I like the GPLv3 but I am not sure if I can use it in this case especially since I am making some money off of google ad's on the site and plan on using amazon affiliates as well. Any help would be greatly appreciated. I do want to open it up as much as possible. But I still want to be able to continue with my own implementation. Thanks in advance for any information or help anyone can provide.

• This web site needs a different Google Maps API key. A new key can be generated at http://code.googl

  - by MJI

  Apologies in advance if this is the wrong place to post. I tried searching for this issue and all that seemed to come up were questions posted from people who had this issue with their web pages. I couldn't find questions related to this issue from a laypersons perspective. I'm not a developer. I have no domain, nor wish to have one at the time. Rather I'm just a regular person who likes to upload photos to some photo related sites. My uploading process constantly gets interrupted by one of these annoying API errors. I get it at least two times, one when I click the page to upload, and also right after it has uploaded. It also pops up if I go to edit a photo or delete it. This interrupts my browsing experience until I click okay. I just want a fix for the annoying without having to register for a key. I tried before and it required a web domain. I rather not have to create a domain and go through such hoops just to fix this. Is there a solution for this problem that doesn't require registration? Another thing to note: I have used two computers. One has the message pop-up and the other doesn't. What is different about the two computers?

• Building a Store Locator ASP.NET Application Using Google Maps API (Part 3)

  Over the past two weeks I've showed how to build a store locator application using ASP.NET and the free Google Maps API and Google's geocoding service. Part 1 looked at creating the database to record the store locations. This database contains a table named Stores with columns capturing each store's address and latitude and longitude coordinates. Part 1 also showed how to use Google's geocoding service to translate a user-entered address into latitude and longitude coordinates, which could then be used to retrieve and display those stores within (roughly) a 15 mile area. At the end of Part 1, the results page listed the nearby stores in a grid. In Part 2 we used the Google Maps API to add an interactive map to the search results page, with each nearby store displayed on the map as a marker. The map added in Part 2 certainly improves the search results page, but the way the nearby stores are displayed on the map leaves a bit to be desired. For starters, each nearby store is displayed on the map using the same marker icon, namely a red pushpin. This makes it difficult to match up the nearby stores listed in the grid with those displayed on the map. Hovering the mouse over a marker on the map displays the store number in a tooltip, but ideally a user could click a marker to see more detailed information about the store, such as its address, phone number, a photo of the storefront, and so forth. This third and final installment shows how to enhance the map created in Part 2. Specifically, we'll see how to customize the marker icons displayed in the map to make it easier to identify which marker corresponds to which nearby store location. We'll also look at adding rich popup windows to each marker, which includes detailed store information and can be updated further to include pictures and other HTML content. Read on to learn more!

• Anunciando: Grandes Melhorias para Web Sites da Windows Azure

  - by Leniel Macaferi

  Estou animado para anunciar algumas grandes melhorias para os Web Sites da Windows Azure que introduzimos no início deste verão.  As melhorias de hoje incluem: uma nova opção de hospedagem adaptável compartilhada de baixo custo, suporte a domínios personalizados para websites hospedados em modo compartilhado ou em modo reservado usando registros CNAME e A-Records (o último permitindo naked domains), suporte para deployment contínuo usando tanto CodePlex e GitHub, e a extensibilidade FastCGI. Todas essas melhorias estão agora online em produção e disponíveis para serem usadas imediatamente. Nova Camada Escalonável "Compartilhada" A Windows Azure permite que você implante e hospede até 10 websites em um ambiente gratuito e compartilhado com múltiplas aplicações. Você pode começar a desenvolver e testar websites sem nenhum custo usando este modo compartilhado (gratuito). O modo compartilhado suporta a capacidade de executar sites que servem até 165MB/dia de conteúdo (5GB/mês). Todas as capacidades que introduzimos em Junho com esta camada gratuita permanecem inalteradas com a atualização de hoje. Começando com o lançamento de hoje, você pode agora aumentar elasticamente seu website para além desta capacidade usando uma nova opção "shared" (compartilhada) de baixo custo (a qual estamos apresentando hoje), bem como pode usar a opção "reserved instance" (instância reservada) - a qual suportamos desde Junho. Aumentar a capacidade de qualquer um desses modos é fácil. Basta clicar na aba "scale" (aumentar a capacidade) do seu website dentro do Portal da Windows Azure, escolher a opção de modo de hospedagem que você deseja usar com ele, e clicar no botão "Salvar". Mudanças levam apenas alguns segundos para serem aplicadas e não requerem nenhum código para serem alteradas e também não requerem que a aplicação seja reimplantada/reinstalada: A seguir estão mais alguns detalhes sobre a nova opção "shared" (compartilhada), bem como a opção existente "reserved" (reservada): Modo Compartilhado Com o lançamento de hoje, estamos introduzindo um novo modo de hospedagem de baixo custo "compartilhado" para Web Sites da Windows Azure. Um website em execução no modo compartilhado é implantado/instalado em um ambiente de hospedagem compartilhado com várias outras aplicações. Ao contrário da opção de modo free (gratuito), um web-site no modo compartilhado não tem quotas/limite máximo para a quantidade de largura de banda que o mesmo pode servir. Os primeiros 5 GB/mês de banda que você servir com uma website compartilhado é grátis, e então você passará a pagar a taxa padrão "pay as you go" (pague pelo que utilizar) da largura de banda de saída da Windows Azure quando a banda de saída ultrapassar os 5 GB. Um website em execução no modo compartilhado agora também suporta a capacidade de mapear múltiplos nomes de domínio DNS personalizados, usando ambos CNAMEs e A-records para tanto. O novo suporte A-record que estamos introduzindo com o lançamento de hoje oferece a possibilidade para você suportar "naked domains" (domínios nús - sem o www) com seus web-sites (por exemplo, http://microsoft.com além de http://www.microsoft.com). Nós também, no futuro, permitiremos SSL baseada em SNI como um recurso nativo nos websites que rodam em modo compartilhado (esta funcionalidade não é suportada com o lançamento de hoje - mas chagará mais tarde ainda este ano, para ambos as opções de hospedagem - compartilhada e reservada). Você paga por um website no modo compartilhado utilizando o modelo padrão "pay as you go" que suportamos com outros recursos da Windows Azure (ou seja, sem custos iniciais, e você só paga pelas horas nas quais o recurso estiver ativo). Um web-site em execução no modo compartilhado custa apenas 1,3 centavos/hora durante este período de preview (isso dá uma média de $ 9.36/mês ou R$ 19,00/mês - dólar a R$ 2,03 em 17-Setembro-2012) Modo Reservado Além de executar sites em modo compartilhado, também suportamos a execução dos mesmos dentro de uma instância reservada. Quando rodando em modo de instância reservada, seus sites terão a garantia de serem executados de maneira isolada dentro de sua própria VM (virtual machine - máquina virtual) Pequena, Média ou Grande (o que significa que, nenhum outro cliente da Windows azure terá suas aplicações sendo executadas dentro de sua VM. Somente as suas aplicações). Você pode executar qualquer número de websites dentro de uma máquina virtual, e não existem quotas para limites de CPU ou memória. Você pode executar seus sites usando uma única VM de instância reservada, ou pode aumentar a capacidade tendo várias instâncias (por exemplo, 2 VMs de médio porte, etc.). Dimensionar para cima ou para baixo é fácil - basta selecionar a VM da instância "reservada" dentro da aba "scale" no Portal da Windows Azure, escolher o tamanho da VM que você quer, o número de instâncias que você deseja executar e clicar em salvar. As alterações têm efeito em segundos: Ao contrário do modo compartilhado, não há custo por site quando se roda no modo reservado. Em vez disso, você só paga pelas instâncias de VMs reservadas que você usar - e você pode executar qualquer número de websites que você quiser dentro delas, sem custo adicional (por exemplo, você pode executar um único site dentro de uma instância de VM reservada ou 100 websites dentro dela com o mesmo custo). VMs de instâncias reservadas têm um custo inicial de $ 8 cents/hora ou R$ 16 centavos/hora para uma pequena VM reservada. Dimensionamento Elástico para Cima/para Baixo Os Web Sites da Windows Azure permitem que você dimensione para cima ou para baixo a sua capacidade dentro de segundos. Isso permite que você implante um site usando a opção de modo compartilhado, para começar, e em seguida, dinamicamente aumente a capacidade usando a opção de modo reservado somente quando você precisar - sem que você tenha que alterar qualquer código ou reimplantar sua aplicação. Se o tráfego do seu site diminuir, você pode diminuir o número de instâncias reservadas que você estiver usando, ou voltar para a camada de modo compartilhado - tudo em segundos e sem ter que mudar o código, reimplantar a aplicação ou ajustar os mapeamentos de DNS. Você também pode usar o "Dashboard" (Painel de Controle) dentro do Portal da Windows Azure para facilmente monitorar a carga do seu site em tempo real (ele mostra não apenas as solicitações/segundo e a largura de banda consumida, mas também estatísticas como a utilização de CPU e memória). Devido ao modelo de preços "pay as you go" da Windows Azure, você só paga a capacidade de computação que você usar em uma determinada hora. Assim, se o seu site está funcionando a maior parte do mês em modo compartilhado (a $ 1.3 cents/hora ou R$ 2,64 centavos/hora), mas há um final de semana em que ele fica muito popular e você decide aumentar sua capacidade colocando-o em modo reservado para que seja executado em sua própria VM dedicada (a $ 8 cents/hora ou R$ 16 centavos/hora), você só terá que pagar os centavos/hora adicionais para as horas em que o site estiver sendo executado no modo reservado. Você não precisa pagar nenhum custo inicial para habilitar isso, e uma vez que você retornar seu site para o modo compartilhado, você voltará a pagar $ 1.3 cents/hora ou R$ 2,64 centavos/hora). Isto faz com que essa opção seja super flexível e de baixo custo. Suporte Melhorado para Domínio Personalizado Web sites em execução no modo "compartilhado" ou no modo "reservado" suportam a habilidade de terem nomes personalizados (host names) associados a eles (por exemplo www.mysitename.com). Você pode associar múltiplos domínios personalizados para cada Web Site da Windows Azure. Com o lançamento de hoje estamos introduzindo suporte para registros A-Records (um recurso muito pedido pelos usuários). Com o suporte a A-Record, agora você pode associar domínios 'naked' ao seu Web Site da Windows Azure - ou seja, em vez de ter que usar www.mysitename.com você pode simplesmente usar mysitename.com (sem o prefixo www). Tendo em vista que você pode mapear vários domínios para um único site, você pode, opcionalmente, permitir ambos domínios (com www e a versão 'naked') para um site (e então usar uma regra de reescrita de URL/redirecionamento (em Inglês) para evitar problemas de SEO). Nós também melhoramos a interface do usuário para o gerenciamento de domínios personalizados dentro do Portal da Windows Azure como parte do lançamento de hoje. Clicando no botão "Manage Domains" (Gerenciar Domínios) na bandeja na parte inferior do portal agora traz uma interface de usuário personalizada que torna fácil gerenciar/configurar os domínios: Como parte dessa atualização nós também tornamos significativamente mais suave/mais fácil validar a posse de domínios personalizados, e também tornamos mais fácil alternar entre sites/domínios existentes para Web Sites da Windows Azure, sem que o website fique fora do ar. Suporte a Deployment (Implantação) contínua com Git e CodePlex ou GitHub Um dos recursos mais populares que lançamos no início deste verão foi o suporte para a publicação de sites diretamente para a Windows Azure usando sistemas de controle de código como TFS e Git. Esse recurso fornece uma maneira muito poderosa para gerenciar as implantações/instalações da aplicação usando controle de código. É realmente fácil ativar este recurso através da página do dashboard de um web site: A opção TFS que lançamos no início deste verão oferece uma solução de implantação contínua muito rica que permite automatizar os builds e a execução de testes unitários a cada vez que você atualizar o repositório do seu website, e em seguida, se os testes forem bem sucedidos, a aplicação é automaticamente publicada/implantada na Windows Azure. Com o lançamento de hoje, estamos expandindo nosso suporte Git para também permitir cenários de implantação contínua integrando esse suporte com projetos hospedados no CodePlex e no GitHub. Este suporte está habilitado para todos os web-sites (incluindo os que usam o modo "free" (gratuito)). A partir de hoje, quando você escolher o link "Set up Git publishing" (Configurar publicação Git) na página do dashboard de um website, você verá duas opções adicionais quando a publicação baseada em Git estiver habilitada para o web-site: Você pode clicar em qualquer um dos links "Deploy from my CodePlex project" (Implantar a partir do meu projeto no CodePlex) ou "Deploy from my GitHub project"  (Implantar a partir do meu projeto no GitHub) para seguir um simples passo a passo para configurar uma conexão entre o seu website e um repositório de código que você hospeda no CodePlex ou no GitHub. Uma vez que essa conexão é estabelecida, o CodePlex ou o GitHub automaticamente notificará a Windows Azure a cada vez que um checkin ocorrer. Isso fará com que a Windows Azure faça o download do código e compile/implante a nova versão da sua aplicação automaticamente.  Os dois vídeos a seguir (em Inglês) mostram quão fácil é permitir esse fluxo de trabalho ao implantar uma app inicial e logo em seguida fazer uma alteração na mesma: Habilitando Implantação Contínua com os Websites da Windows Azure e CodePlex (2 minutos) Habilitando Implantação Contínua com os Websites da Windows Azure e GitHub (2 minutos) Esta abordagem permite um fluxo de trabalho de implantação contínua realmente limpo, e torna muito mais fácil suportar um ambiente de desenvolvimento em equipe usando Git: Nota: o lançamento de hoje suporta estabelecer conexões com repositórios públicos do GitHub/CodePlex. Suporte para repositórios privados será habitado em poucas semanas. Suporte para Múltiplos Branches (Ramos de Desenvolvimento) Anteriormente, nós somente suportávamos implantar o código que estava localizado no branch 'master' do repositório Git. Muitas vezes, porém, os desenvolvedores querem implantar a partir de branches alternativos (por exemplo, um branch de teste ou um branch com uma versão futura da aplicação). Este é agora um cenário suportado - tanto com projetos locais baseados no git, bem como com projetos ligados ao CodePlex ou GitHub. Isto permite uma variedade de cenários úteis. Por exemplo, agora você pode ter dois web-sites - um em "produção" e um outro para "testes" - ambos ligados ao mesmo repositório no CodePlex ou no GitHub. Você pode configurar um dos websites de forma que ele sempre baixe o que estiver presente no branch master, e que o outro website sempre baixe o que estiver no branch de testes. Isto permite uma maneira muito limpa para habilitar o teste final de seu site antes que ele entre em produção. Este vídeo de 1 minuto (em Inglês) demonstra como configurar qual branch usar com um web-site. Resumo Os recursos mostrados acima estão agora ao vivo em produção e disponíveis para uso imediato. Se você ainda não tem uma conta da Windows Azure, você pode inscrever-se em um teste gratuito para começar a usar estes recursos hoje mesmo. Visite o O Centro de Desenvolvedores da Windows Azure (em Inglês) para saber mais sobre como criar aplicações para serem usadas na nuvem. Nós teremos ainda mais novos recursos e melhorias chegando nas próximas semanas - incluindo suporte para os recentes lançamentos do Windows Server 2012 e .NET 4.5 (habilitaremos novas imagens de web e work roles com o Windows Server 2012 e NET 4.5 no próximo mês). Fique de olho no meu blog para detalhes assim que esses novos recursos ficarem disponíveis. Espero que ajude, - Scott P.S. Além do blog, eu também estou utilizando o Twitter para atualizações rápidas e para compartilhar links. Siga-me em: twitter.com/ScottGu Texto traduzido do post original por Leniel Macaferi.

• Migrate ASP.Net web site from IIS6 to IIS7

  - by David.Chu.ca

  I have to migrate an ASP.Net web site from IIS6 to IIS7. I tried to copy the all files for a web site from IIS6 (c:\inetpub\wwwroot\MySite) to another box with Windows Server 2008 R2 where IIS7 is the default web server. However, the simply copy seems not working. Should I rebuild the web site for IIS7 or should I make changes on the new box with IIS7 such as web.config? Thanks for the comments. Further investigation I found that http handers seems caused exception: <!--httpHandlers> <add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" validate="false"/> </httpHandlers--> After I comment out the above handler in web.config, the web page works fine. This is just my initial test. I am not sure if I should rebuild the web site from source codes or not. If so, do I need to specify for IIS7?

• How to enable services Discovery API in GoogleCL?

  - by Marcos

  There are bits and pieces of information all over the place but I'm trying to put it all together so that GoogleCL finally accesses more than the initial 7 services. Does anyone know of a step-by-step? Right now any attempt outside these result in the error message: google tasks list Did you specify the service correctly? Must be one of 'picasa', 'blogger', 'youtube', 'docs', 'contacts', 'calendar', 'finance' I installed GoogleCL from the Ubuntu repos, authenticated a few bundled services like contacts, docs etc. and those work great, giving me access to do certain operations like upload from the command line. I would really like to get it going to support tasks and all the other elegible Google services shown at https://code.google.com/apis/explorer/#_s=tasks Here are some guides/partial steps I've found: http://code.google.com/p/googlecl/wiki/DiscoveryManual (indicates needing to check it out updated GoogleCL from the subversion repository.) http://code.google.com/p/google-api-python-client/wiki/Installation easy_install --upgrade google-api-python-client http://code.google.com/p/googlecl/wiki/Install http://code.google.com/p/googlecl/source/checkout sudo -i cd /usr/local/src/ svn checkout http://googlecl.googlecode.com/svn/trunk/ googlecl-read-only cat googlecl-read-only/INSTALL.txt cd /usr/local/src/googlecl-read-only/ python setup.py install Result: $ google discovery list Traceback (most recent call last): File "/usr/bin/google", line 488, in run_interactive run_once(options, args) File "/usr/bin/google", line 540, in run_once options.config) File "/usr/bin/google", line 364, in import_service force_gdata_v1 = config.lazy_get(package.SECTION_HEADER, AttributeError: 'module' object has no attribute 'SECTION_HEADER'

• Writing files in a sub folder of the web folder (apache security)

  - by Homunculus Reticulli

  I need to save session data for a dynamic web page script by writing to file. I have two questions: Are there any security preferences as to whether to save the data UNDER the web folder, or OUTSIDE the web folder? I attempted to write to the folder an (unsuprisingly), I had a 'file permission refused' type error. Should I set the folder ownership to the apache user (600, 640 or 644?) [[Edit]] core <- 'OUTSIDE' web folder (php script live here) data <- 'OUTSIDE' web folder (session data and other misc data resides here) web <- web root folder js <- any folder below is 'INSIDE' the web folder css html For example, in a php script (i.e. a dynamic PHP page), I can attempt to write to a file using something like fput('../data',data) yet (as I understand it) ../data should not be accessible - for security reasons. Could someone please provide a simple example that shows how to provide access to ../data/ in the example given above?. What are the actual SPECIFIC steps required? BTW, I am running on a LAMP stack.

• Handling SEO for Infinite pages that cause external slow API calls

  - by Noam

  I have an 'infinite' amount of pages in my site which rely on an external API. Generating each page takes time (1 minute). Links in the site point to such pages, and when a users clicks them they are generated and he waits. Considering I cannot pre-create them all, I am trying to figure out the best SEO approach to handle these pages. Options: Create really simple pages for the web spiders and only real users will fetch the data and generate the page. A little bit 'afraid' google will see this as low quality content, which might also feel duplicated. Put them under a directory in my site (e.g. /non-generated/) and put a disallow in robots.txt. Problem here is I don't want users to have to deal with a different URL when wanting to share this page or make sense of it. Thought about maybe redirecting real users from this URL back to the regular hierarchy and that way 'fooling' google not to get to them. Again not sure he will like me for that. Letting him crawl these pages. Main problem is I can't control to rate of the API calls and also my site seems slower than it should from a spider's perspective (if he only crawled the generated pages, he'd think it's much faster). Which approach would you suggest?

• difference between Casini [IIS express] and VS Development server or Expression web

  - by anirudha

  MVC3 project can be run within Expression web and Visual studio as opened like a website not a project. they work same even if you open blogengine.net project in VS they take a time when you have more theme but expression web debug them in a second. well because theme design not matter for code. Expression web is a good because they save time for compile the code. even changes we make a little in design nothing in backend code.   i found a little difference between Casini and VS development server that if image putted in wrong way like <img src=”//img.png”/> instead of <img src=”/img.png”/> the error we make // instead of / that’s not worked in Expression web or Visual studio debugging but in Cassini it’s work fine.   Well i found that debug Blogengine.net in Expression web is a great thing because in VS they take a time like a minute to debug when you trying to debug first time. Expression Web save a time when we design themes within them and that’s much good option because web is also maked for design.   Well if you want to debug application faster then use casini but Expression web debugging is a good option when they take a long time to debug in Visual studio and EW debug them in a seconds.

• How to get initial API right using TDD?

  - by Vytautas Mackonis

  This might be a rather silly question as I am at my first attempts at TDD. I loved the sense of confidence it brings and generally better structure of my code but when I started to apply it on something bigger than one-class toy examples, I ran into difficulties. Suppose, you are writing a library of sorts. You know what it has to do, you know a general way of how it is supposed to be implemented (architecture wise), but you keep "discovering" that you need to make changes to your public API as you code. Perhaps you need to transform this private method into strategy pattern (and now need to pass a mocked strategy in your tests), perhaps you misplaced a responsibility here and there and split an existing class. When you are improving upon existing code, TDD seems a really good fit, but when you are writing everything from scratch, the API you write tests for is a bit "blurry" unless you do a big design up front. What do you do when you already have 30 tests on the method that had its signature (and for that part, behavior) changed? That is a lot of tests to change once they add up.

• Using Coherence API to get POF bytes

  - by Bruno.Borges

  Someone raised the question on how to use the Coherence API to get the bytes of an object in POF (Portable Object Format) programatically. So I came up with this small code that shows the very cool API simple usage :-)   SimplePofContext spc = new SimplePofContext();    spc.registerUserType(0, User.class, new UserSerializer());    // consider UserSerializer as an implementation of PofSerializer            User u = new User();    u.setId(21);    u.setName("Some Name");    u.setEmail("[email protected]");            ByteArrayOutputStream baos = new ByteArrayOutputStream();    DataOutput dataOutput = new DataOutputStream(baos);    BufferOutput bufferOutput = new WrapperBufferOutput(dataOutput);    spc.serialize(bufferOutput, u);            byte[] byteArray = baos.toByteArray();    System.out.println(Arrays.toString(byteArray));  Easy, isn't?

• API Class with intensive network requests

  - by Marco Acierno

  I'm working an API which works as "intermediary" between a REST API and the developer. In this way, when the programmer do something like this: User user = client.getUser(nickname); it will execute a network request to download from the service the data about the user and then the programmer can use the data by doing things like user.getLocation(); user.getDisplayName(); and so on. Now there are some methods like getFollowers() which execute another network request and i could do it in two ways: Download all the data in the getUser method (and not only the most important) but in this way the request time could be very long since it should execute the request to various urls Download the data when the user calls the method, it looks like the best way and to improve it i could cache the result so the next call to getFollowers returns immediately with the data already download instead of execute again the request. What is the best way? And i should let methods like getUser and getFollowers stop the code execution until the data is ready or i should implement a callback so when the data is ready the callback gets fired? (this looks like Javascript)

• Authenticate native mobile app using a REST API

  - by Supercell

  I'm starting a new project soon, which is targeting mobile application for all major mobile platforms (iOS, Android, Windows). It will be a client-server architecture. The app is both informational and transactional. For the transactional part, they're required to have an account and log in before a transaction can be made. I'm new to mobile development, so I don't know how the authentication part is done on these platforms. The clients will communicate with the server through a REST API. Will be using HTTPS ofcourse. I haven't yet decided if I want the user to log in when they open the app, or only when they perform a transaction. I got the following questions: 1) Like the Facebook application, you only enter your credentials when you open the application for the first time. After that, you're automatically signed in every time you open the app. How does one accomplish this? Just simply by encrypting and storing the credentials on the device and sending them every time the app starts? 2) Do I need to authenticate the user for each (transactional) request made to the REST API or use a token based approach? Please feel free to suggest other ways for authentication. Thanks!

• Google Currency Convertor JSON API

  - by Gopinath

  There are many live currency conversion services available on the web and the popular one’s among them are – Google, Yahoo, MSN & XE. Among all these four Google is the developer’s darling and it provides a simple JSON API that can be integrated in your applications.  http://www.google.com/ig/calculator?hl=en&q=1USD=?INR Using the API is very simple and it takes two parameters as input. The first parameter “hl” is the language code in which you want output. The second parameter “q” is the conversion query in the format <number><from currency code>=?<to currency code>. In the URL give above the query requests for conversion of 1 USD in INR. JSON output for the above query would be  similar to {lhs: "1 U.S. dollar",rhs: "54.4602984 Indian rupees",error: "",icc: true} Examples: 100 USD in INR  http://www.google.com/ig/calculator?hl=en&q=100USD=?INR Example 2: 1 GBP in INR http://www.google.com/ig/calculator?hl=en&q=1GBP=?INR Example 3: 1 USD in INR, output the data in French language http://www.google.com/ig/calculator?hl=fr&q=1USD=?INR   This is an undocumented service and expect changes at any time. But as long as it works, you got a programmatic way to convert currencies.
