  • how to upload a audio file using REST webservice in Google App Engine for Java

    - by sathya
    Am using google app engine with eclipse IDE and trying to upload a audio file. I used the File Upload in Google App Engine For Java and can able to upload the file successfully. Now am planning to use REST web service for it. I had analyzed in developers.google but i failed. Can anyone suggest me how to implement REST Web services in google app engine using Eclipse. The code google provided is shown below, // file Upload.java public class Upload extends HttpServlet { private BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException { Map<String, BlobKey> blobs = blobstoreService.getUploadedBlobs(req); BlobKey blobKey = blobs.get("myFile"); if (blobKey == null) { res.sendRedirect("/"); } else { res.sendRedirect("/serve?blob-key=" + blobKey.getKeyString()); }}} // file Serve.java public class Serve extends HttpServlet { private BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); public void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException { BlobKey blobKey = new BlobKey(req.getParameter("blob-key")); blobstoreService.serve(blobKey, res); }} // file index.jsp <%@ page import="com.google.appengine.api.blobstore.BlobstoreServiceFactory" %> <%@ page import="com.google.appengine.api.blobstore.BlobstoreService" %> <% BlobstoreService blobstoreService = BlobstoreServiceFactory.getBlobstoreService(); %> <form action="<%= blobstoreService.createUploadUrl("/upload") %>" method="post" enctype="multipart/form-data"> <input type="file" name="myFile"> <input type="submit" value="Submit"> </form> // web.xml <servlet> <servlet-name>Upload</servlet-name> <servlet-class>Upload</servlet-class> </servlet> <servlet> <servlet-name>Serve</servlet-name> <servlet-class>Serve</servlet-class> </servlet> <servlet-mapping> <servlet-name>Upload</servlet-name> <url-pattern>/upload</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>Serve</servlet-name> <url-pattern>/serve</url-pattern> </servlet-mapping> Now how to provide a rest web service for the above code. Kindly suggest me an idea.

  • Online Game programming in Google App Engine: AI

    - by Hortinstein
    I am currently in the planning stages of a game for google app engine, but cannot wrap my head around how I am going to handle AI. I intend to have persistant NPCs that will move about the map, but short of writing a program that generates the same XML requests I use to control player actions, than run it on another server I am stuck on how to do it. I have looked at the Task Queue feature, but due to long running processes not being an option on the App engine, I am a little stuck. I intend to run multiple server instances with 200+ persistant NPC entities that I will need to update. Most action is slowly roaming around based on player movements/concentrations, and attacking close range players(you can probably guess the type of game im developing)

  • Using VB6 to search for existence of DataFile in Outlook

    - by Graeme
    Hi, I am wanting to write an Add-In for Outlook 2003 which, when Outlook is opened, search for the existence of a datafile called DMSDataStore and if it doesn't exist will install the datafile. I have managed to create the Add-In using VB6 and it runs when I open Outlook. However I haven't found the best/easiest way to search for the existence of the datafile. If the datafile exists it is visible within Outlook under the user's mailbox, much the same as an archive folder is. I would like to be able to search for it by name which is DMSDataFile. I did try - Set tmpInbox = parentFolder.Folders("DMSDataFile") This works OK if the datafile exists but will throw an error if it doesn't. I can create an error handler which will then install the datafile but this doesn't seem like a very tidy way of doing things. I guess I might have to recursively search for the datafile. Can someone let me know what is the best / easiest way to search for the datafile using the name of the datafile and give me some code with which to do it. Thanks G

  • What alternatives are there to Google App Engine?

    - by Chris Marasti-Georg
    What alternatives are there to GAE, given that I already have a good bit of code working that I would like to keep. In other words, I'm digging python. However, my use case is more of a low number of requests, higher CPU usage type use case, and I'm worried that I may not be able to stay with App Engine forever. I have heard a lot of people talking about Amazon Web Services and other sorts of cloud providers, but I am having a hard time seeing where most of these other offerings provide the range of services (data querying, user authentication, automatic scaling) that App Engine provides. What are my options here?

  • google search rankings and trends api

    - by Drakkhen
    I'm looking to find an api or program or interface to get the following information. I would like to see the amount of times a particular search term was used and its /weekly/monthly/yearly breakdown along with its rank in a particular page. I've found googlesearchpositionfinder.com and google.com/trends but i have 5000 terms to search for by hand is not happening. I've also found www.juiceanalytics.com/openjuice/programmatic-google-trends-api but it doesn't allow me to do a break down for a period of 2 years. Basically i'm trying to create a ranking of search phrases, the weeks(period) they were more popular and how a particular site(e.g urban dictionary) showed up in googles search rankings for the terms.

  • Google app engine sessions now supported???

    - by user246114
    Hi, I thought google app engine did not support sessions (last time I checked was a few months ago). Now I was searching again for it and saw this: http://code.google.com/appengine/docs/java/config/appconfig.html#Enabling_Sessions says it supports: javax.servlet.http.HttpSession does this mean we have servlet session support now? If so, does anyone have an example of using this? I wanted to create my own User class and support user login and session management (I know app engine already supports this for google users, but wanted my own users for various requirements) Thanks!

  • Android Full Text Search

    - by Eduardo
    Does Android come with a way to do Full Text Search? I know is it not even possible to search contacts by the notes field, being Google the search company, but I would be disappointed if there is no API for that.

  • How can I search for the dot character using the search command?

    - by lk
    I'm trying to use the Search command in Vim: :Rs/F/T/X R = range F = text to find T = text to replace with X = options But, when I want to search for the "." (dot character) I'm getting some problems. The task: Replace all occurences of " ." (space dot) for "" (greater-than) So, first I tried this: :%s/ ./>/g But this changed me all the " ." (space ANY-CHARACTER) to the "" character. Then I remembered that the dot character is a special one, so I tried this: :%s/ \./>/g But vim threw me an error: E486 Can't find pattern " \." And finally I tried this crazy thing: :%s/" ."/>/g and this :%s/" \."/>/g But I got the same result: E486 Can't find pattern... So, how can I search for the dot character using the search command? PS: Sorry for my poor Enlish.

  • Fake Template Engine php

    - by user1464822
    i got an idea for making php template engine fast and user friendly but i'm not sure if it's good or bad. the idea is to create a fake template engine: creating a template editor in control panel that let user see something like this: <html> <head> <title>{title}</title> </head> <body> {content} </body> </html> what the editor actually does is to replace all php code like <?php echo $this->title; ?> to user friendly {title} but it's not really replacing it just in the view when the user save the template the template actually saved as fast pure php template. the question is this a good idea or bad ? your answers is highly appreciated.

  • Android game engine for 2d and 3d games?

    - by javame_android
    Hi, There is a library called cocos-2d for iphone. There are number of games developed with that nowadays. Also, there is cocos-2d library available for Android too. I just wanted to know if that is also as stable as iphone one or its still not stable to be used in development. Also, is there any other game engine available for Android? The ones that I know is AndEngine. Which one is better for development? If not both then will it better to develop using core Android API rather than using any game engine.

  • Indexing File Contents

    - by Rafid K. Abdullah
    People seem to have already asked about indexing file system: What options are there for indexing my filesystem? Alternatives to OS X's Spotlight? but I want to actually just index a certain working directory and be able to do that manually (so that I make sure my search is correct). Basically, I am on working a project and I need be able to search in contents quickly. I already use 'locate' and 'updatedb' commands, but those search for file names only. I am looking for similar commands but file contents. Just in case you are wondering why I don't use tracker also like answered in the two posts, tracker have a set of prespecified folders to search in them, and whenever you make a search, you search in all of them. What I want is to be able to search in every project separately.

  • Portlet container like pluto or jetspeed on google app engine?

    - by Patrick Cornelissen
    I am trying to build something "portlet server"-ish on the google app engine. (as open source) I'd like to use the JSR168/286 standards, but I think that the restrictions of the app engine will make it somewhere between tricky and impossible. Has anyone tried to run jetspeed or an application that uses pluto internally on the google app engine? Based on my current knowledge of portlets and the google app engine I'm anticipating these problems: A war file with portlets is from the deployment standpoint more or less a complete webapp (yes, I know that it doesn't really work without a portal server). The war file may contain it's own web.xml etc. This makes deployment on the app engine rather difficult, because the apps are not visible to each other, so all portlet containing archives need to be included in the war file of the deployed "app engine based portal server". The "portlets" are (at least in liferay) started as permanent servlet processes, based on their portlet.xmls and web.xmls which is located in the same spot for every portlet archive that is loaded. I think this may be problematic in the app engine, because everything is in one big "web app", so it may be tricky to access the portlet.xmls from each archive. This prevents a 100% compatibility in my opinion. Is here anyone who has any experience with the combination of portlets and the app engine? Do you think it's feasible to modify jetspeed, pluto or any other portlet container to be able to run it on the app engine?

  • How do I control how often search engines visit my site?

    - by Nick
    I've been using the following line in the <head> of my sites for years: <meta name="revisit-after" content="3 days" /> I recently discovered that it's not one of the meta tags that Google understands, which I take to mean that there's no point in including it, and that it's been doing no good at all for years. How often do search engines crawl a website by default, and what reliable ways are there to increase or decrease that frequency?

  • Is it possible (and practical) to search a string for arbitrary-length repeating patterns?

    - by blz
    I've recently developed a huge interest in cryptography, and I'm exploring some of the weaknesses of ECB-mode block ciphers. A common attack scenario involves encrypted cookies, whose fields can be represented as (relatively) short hex strings. Up until now, I've relied on my eyes to pick out repeating blocks, but this is rather tedious. I'm wondering what kind of algorithms (if any) could help me automate my search for repeating patterns within a string. Can anybody point me in the right direction?

  • which file search utilities also include a preview of found lines?

    - by jcollum
    I've searched for this and haven't found it, maybe I'm not using the right terms. I'm looking for a file search utility in Windows 7 that will: search for files in specific directories search for file contents preview found lines (preferably with a couple of lines around the found line) save search terms as presets (like *.aspx.cs or *.cs or a combination of the two) search in office documents Notepad++ will do this but I'm looking for something that also adds indexing so it's faster. Locate32 does most of it, but doesn't have a preview. Seems that all of the file search utilities that I've found don't do what I want.

  • All About Search Engine Position Optimization

    Search engine optimization or SEO is a method increasing the amount of traffic or hits to your website, which results in making your website rank high in search engine results. These results are produced whenever an individual types in a keyword or a set of keywords in a search query in search engines like Yahoo!, Google and the like. Being high on the list of search results matters a lot because it makes you more visible to the general public, especially to your target market. This differentiates you from your competitors who may rank low in the search results, or may not even appear in the results lists at all.
