  • Do I need to use C3P0 pooling library in my (grails) web application?

    - by fabien7474
    Hi, I am not familiar at all with connection pooling library. I've just discovered it through this blog article) and I am not sure that I should use one in my web application based on grails/hibernate/mysql. So my question is simple : in which situations would you suggest to integrate a connection pooling library into a grails application? Always, Never or only over some connections threshold? P.S. : If you have ever used successfully C3P0 in your web application, I will greatly appreciate to hear your feedback (in terms of visible positive effects).

  • Can't set up IIS Web Server on Server 2008 x64 correctly (what have I missed?)

    - by balexandre
    Using a VM I installed Windows 2008 Server x64 and as the image below shows, added the IIS Role full image and assigned all role features of IIS full image But if I have an ASP.NET (aspx) page that does (C#) Session["test-session"] = "A"; and read in other page I always get nothing! NOTE: I do have an entire ASP.NET web application, the example above is to be succinct and explicit on what is the problem I'm facing. Can anyone know what do I have to do to the Server, so I can use the Session variables? All help is greatly appreciated, Thank you

  • 403 Forbidden error on Mac OSX - Apache and nginx

    - by tlianza
    Hi All, There are a million questions like this on Google, but I haven't found a solution to my problem. The default Apache install on my Mac is giving 403 Forbidden errors for everything (default directory, user home directory, virtual server, etc). After sifting through the config files, I figured I'd give nginx a try. Nginx serves files fine from it's home directory, but it won't serve files from a subfolder of my user directory. I've configured a simple virtual host, and requesting index.html returns a 403-forbidden. The error message in nginx's log file is pretty clear - it can't read the file: 2011/01/04 16:13:54 [error] 96440#0: *11 open() "/Users/me/Documents/workspace/mobile/index.html" failed (13: Permission denied), client: 127.0.0.1, server: local.test.com, request: "GET /index.html HTTP/1.1", host: "local.test.com" I've opened up this directory to everyone: drwxrwxrwx 6 me admin 204B Dec 31 20:49 mobile And all the files in it: $ ls -lah mobile/ total 24 drwxrwxrwx 6 me admin 204B Dec 31 20:49 . drwxr-xr-x 71 me me 2.4K Dec 31 20:41 .. -rw-r--r--@ 1 me me 6.0K Jan 2 18:58 .DS_Store -rwxrwxrwx 1 me admin 2.1K Jan 4 14:22 index.html drwxrwxrwx 5 me admin 170B Dec 31 20:45 nbproject drwxrwxrwx 5 me admin 170B Jan 2 18:58 script And yet, I cannot figure out why the nginx process cannot read index.html. It's running as the "nobody" user, but the permissions are set such that anyone can read them.

  • Web App Server hardware question. Which configuration?

    - by JBeckton
    I am pricing some new servers and I am not sure which configuration to get. The server will be running some web applications for our company. Some of them are ASP.Net sites and some are ColdFusion. The OS will be Win Server 2008 Web or Standard Edition. Do I need 2 processors or will a single quad core handle it? Xeon multi core Hyperthreading or non Hyperthreading? I am going 64bit so I can go higher than 4 Gigs of Ram. I am shopping at Dell and there are so many options, i do not want to get too much hardware and not use half of it because that would be a waste of money and I do not want to get too little and have to ask for more money to upgrade it later.

  • UAC prompt won't allow non-administrator to access IIS 7 Manager.

    - by Triynko
    The IIS 7 Manager seems to throw up a UAC prompt requiring administrative elevation as soon as the shortcut is clicked. This makes it impossible for a non-admin to use it. When I first created the user account, I could open IIS 7 Manager, but could not connect. I temporarily made the user account an Admin, then opened IIS 7 Manager again. Now that I've removed user from Admin, every time I open IIS 7 Manager it throws up the UAC prompt, making it impossible to do anything with it as a non-Admin. Is this a bug? Is there a way to reset the settings for this user so that IIS 7 Manager is back in some kind of first-run state?

  • What's the easiest/fast way to get my website up and running on the web?

    - by ggfan
    This is probably a really really beginner's question, but I would like to know what's the fastest way to get my site on the web so that people can start using it. I'm learning everything about programming out of books and at home so I don't have much experience. --Before I go to like godaddy.com or such site to get a domain name, is there any free sites that would allow me to upload my site so users can use it? I have html,css,php,mysql,javascipt in my scripts so I don't think many sites allow free uploads with such languages. --If I can't find a free site, is there any good places to get a domain name and web hosting that supports most languages at a low price? (doesn't have to be professional hosting because I am still a beginner) --If I go to say godaddy.com and get their webhosting and domain name, would I be allowed to run php,mysql,python,java on it? (I looked at some hosting sites and most only allow php/mysql)

  • ASP.NET - I am generating an .XLS file with a DLL, how do I grant permissions for writing to file? (

    - by hamlin11
    I'm generating an .XLS file with a DLL (Excel Library http://code.google.com/p/excellibrary/) I've added this DLL as a reference to my project. The code to save the .XLS to disk is running, but it's encountering a permissions issue. I've attempted to set full access for IUSRS, Network Service, and Everyone just to see if I could get it working, and none of these seems to make a difference.

  • It is possible to use the Exchange 2010 web client with an Exchange 2007 mail server?

    - by michielvoo
    We are evaluating our options to upgrade our Windows SBS 2003 server. We are considering Windows SBS 2008, which comes with Exchange 2007 and an extra Windows Server 2008 Standard license. If we also bought Exchange 2010, could we install it on the Windows Server 2008 Standard machine and use the web client in combination with the Exchange 2007 server (that would be hosting the mailboxes)? Is that a supported server role for Exchange 2010? I remember reading about so called front-end server configurations, but I have no experience with that. Thanks!

  • Which web Tier Framework for a public commercial website with heavy load ?

    - by Maxime ARNSTAMM
    Hello everyone, As a part of an enterprise architecture exercise, i need to find a java-based framework filling these constraints : heavy (i think) load : 5000 concurrent connections widely known : can't be too exotic, the contractors would be too high priced. relatively easy to use : developpement time must be reasonnable must be as compliant as possible with the css/html layout produced by a designer Must look like "web 2.0" from the marketing point of view. What i learned from my limited experience is : jsf : 1, don't know. 2, 3 ok. 4 not ok (at least not without huge effort) wicket : 1, not really. 2, 3 and 4 ok. gwt : 1, don't know. 2, 3 ok. 4 not ok (but more ok than jsf) others : not really "web 2.0" or not really known I'm really junior, so my ideas about those frameworks are probably wrong, that's why i come to you, stackoverflowees. Thanks for helping :)

  • Encrypt connection between apache web server and mysql server.

    - by microchasm
    I'm setting up a local webapp. I have a CentOS-5 box that will be the webserver (Apache 2.2). I have another box (RHEL5) that will be used only for MySQL. The data will be encrypted on the webserver via PHP before being sent to the MySQL box and inserted into the db. All web-based connections to the webserver will be encrypted via SSL. From the research I've done, it's not totally clear on whether or not there is a need to encrypt the connection to the db from webserver (NB paranoia level: Orange). If it is not overkill, or even if it is (unless it is a really bad idea for some reason), any advice or pointers on the direction to take to get this done would be appreciated.

  • How to do call function after client finishes download from tornado web server?

    - by Shabbyrobe
    I would like to be able to run some cleanup functions if and only if the client successfully completes the download of a file I'm serving using Tornado. I installed the firefox throttle tool and had it slow the connection down to dialup speed and installed this handler to generate a bunch of rubbish random text: class CrapHandler(BaseHandler): def get(self, token): crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000)) self.write(crap) print "done" I get the following output from tornado immediately after making the request: done I 100524 19:45:45 web:772] 200 GET /123 (192.168.45.108) 195.10ms The client then plods along downloading for about 20 seconds. I expected that it would print "done" after the client was done. Also, if I do the following I get pretty much the same result: class CrapHandler(BaseHandler): @tornado.web.asynchronous def get(self, token): crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000)) self.write(crap) self.finish() print "done" Am I missing something fundamental here? Can tornado even support what I'm trying to do? If not, is there an alternative that does?

  • How to let mod_wsgi only handle certain URLs under Apache?

    - by Frederik
    I have a Django app that handles "/admin/" and "/myapp/". All the other requests should be handled by Apache. I've tried using LocationMatch but then I'd have to write a negative regex. I've tried WSGIScriptAlias with the /admin/ prefix but then the wsgi_handler receives the request with the /admin/ part cut off. Is there a cleaner way to make mod_wsgi only handle certain requests?

  • Web and email host migration - Limitations and suggestions to make the process as easy as possible.

    - by Jack Hickerson
    I developed a website for a friend of mine to replace his current 'all inclusive' provider (website creation, updating, web hosting, email hosting). I've already paid for a hosting service which currently houses the website which I have created. I need to cancel the previous service provider to get the domain migrated to the new host, however I will still need to transfer or recreate all of the email addresses that everyone in his company had previously. Is there an easy way migrate email accounts (still linked to the same domain) while migrating to a different host? Will any methods allow all users to retain their archived emails and folder structures? What is the process to do so. Because the current provider is a rather large website development and hosting company, I will have limited access to the data they have stored. As you can probably tell, my knowledge in this area is very limited - any/all suggestions you may have would be greatly appreciated. Thanks in advance. -Jack

  • Will client JVM for a web service(https) throw an SSL Exception when the server is having a valid ce

    - by ring bearer
    I have a web service deployed on tomcat hosted on a remote server. I have set it up such that it can be accessed only via HTTPS. For this, I generated a Certificate Signing Request (CSR) and used it to get a temporary certificate from VeriSign. My web service client is on my local machine. If I try to access the service it will throw a javax.net.ssl.SSLHandshakeException:unable to find valid certification path to requested target If I install the certificate in to local Java's keystore, the issue will be resolved. My question is if I install a valid SSL certificate from a CA in to my tomcat server, will I get this client-side error even if I do not import the certificate to local key store?

  • browser cookie issue

    - by George2
    Hello everyone, In my previous understanding, for a web site, only login user of a web site (no matter what login/authentication approach is used) could have cookie as persistent identifier, so that if the user close the browser, open browser again to go to the same web site, the web site could remember the user. But I learned recently that it seems for non-login user, there could still be a cookie associated with the user (after the user close browser, and then open the browser again to go to the same web site, the web site could remember the user), and it is called browser cookie? Is that true? If it is true, who is responsible to set the browser cookie? i.e. need some coding/config at web server side, client browser configuration (without coding from server side), or both? How could web server access such cookie? Appreciate if any code samples. thanks in advance, George

  • Basic clarification about Limited FTP/sFTP users

    - by mattewre
    I would like to get some clarification about the correct way to create limited users to access to my VPS user as WEBSERVER with Nginix. I'm used to NOT install FTP and access via SFTP only. It is ok for every set up? this is what I usually do from to create a limited user called "admin" that should be able to have access via SFTP to the folder with the website data mkdir -p /var/www/mysite.com/ adduser admin adduser admin www-data chown -R root:root /var/www chmod -R 755 /var/www chmod -R 755 /var/www/mysite.com chown -R admin:www-data /var/www/mysite.com/ It seems not to be the correct way, I always have problems with permission when I upload some files (for example with Wordpress in general). I would like to create an user that does work exactly as the one that the "provides" give to their client when they buy an Hosting service (that is a FTP, I would prefer SFTP access). It is for personal user, but I think that a limited user is a lot safer to use then the "root" via SFTP.

  • What is a good platform for building a game framework targetting both web and native languages?

    - by fuzzyTew
    I would like to develop (or find, if one is already in development) a framework with support for accelerated graphics and sound built on a system flexible enough to compile to the following: native ppc/x86/x86_64/arm binaries or a language which compiles to them javascript actionscript bytecode or a language which compiles to it (actionscript 3, haxe) optionally java I imagine, for example, creating an API where I can open windows and make OpenGL-like calls and the framework maps this in a relatively efficient manner to either WebGL with a canvas object, 3d graphics in Flash, OpenGL ES 2 with EGL, or desktop OpenGL in an X11, Windows, or Cocoa window. I have so far looked into these avenues: Building the game library in haXe Pros: Targets exist for php, javascript, actionscript bytecode, c++ High level, object oriented language Cons: No support for finally{} blocks or destructors, making resource cleanup difficult C++ target does not allow room for producing highly optimized libraries -- the foreign function interface requires all primitive types be boxed in a wrapper object, as if writing bindings for a scripting language; these feel unideal for real-time graphics and audio, especially exporting low-level functions. Doesn't seem quite yet mature Using the C preprocessor to create a translator, writing programs entirely with macros Pros: CPP is widespread and simple to use Cons: This is an arduous task and probably the wrong tool for the job CPP implementations differ widely in support for features (e.g. xcode cpp has no variadic macros despite claiming C99 compliance) There is little-to-no room for optimization in this route Using llvm's support for multiple backends to target c/c++ to web languages Pros: Can code in c/c++ LLVM is a very mature highly optimizing compiler performing e.g. global inlining Targets exist for actionscript (alchemy) and javascript (emscripten) Cons: Actionscript target is closed source, unmaintained, and buggy. Javascript targets do not use features of HTML5 for appropriate optimization (e.g. linear memory with typed arrays) and are immature An LLVM target must convert from low-level bytecode, so high-level constructs are lost and bloated unreadable code is created from translating individual instructions, which may be more difficult for an unprepared JIT to optimize. "jump" instructions cause problems for languages with no "goto" statements. Using libclang to write a translator from C/C++ to web languages Pros: A beautiful parsing library providing easy access to the code structure Can code in C/C++ Has sponsored developer effort from Apple Cons: Incomplete; current feature set targets IDEs. Basic operators are unexposed and must be manually parsed from the returned AST element to be identified. Translating code prior to compilation may forgo optimizations assumed in c/c++ such as inlining. Creating new code generators for clang to translate into web languages Pros: Can code in C/C++ as libclang Cons: There is no API; code structure is unstable A much larger job than using libclang; the innards of clang are complex Building the game library in Common Lisp Pros: Flexible, ancient, well-developed language Extensive introspection should ease writing translators Translators exist for at least javascript Cons: Unfamiliar language No standardized library functions, widely varying implementations Which of these avenues should I pursue? Do you know of any others, or any systems that might be useful? Does a general project like this exist somewhere already? Thank you for any input.
