  • Ensure a new session every time the user connects to a Servlet

    - by Daziplqa
    Hi, I've a JSP/Servlet Web App that consist of more than one servlet (and some JSPs) I need to create an new HttpSession whenever the users access servlet A, knowing that, servlet A is the home page (i.e. he access it as the first servlet/page in the application) so far so good, I can write the following code at the start of the servlet A: HttpSession session = request.getSession(false); if (session == null) { logger.debug("starting new session..."); session = request.getSession(); // other staff here } But the problem is, if the user didn't close his browser (even if he closes the tab - in firefox for instance - the session will still be open), so when he try to open my site again, the last session will be re-used (in the rage of session timeout ofcourse), and this I don't need. I need whenever he access Servlet A, he got created a brand new HttpSession. but unfortunately, he may access this servlet twice per session based on some scenario!! Please help.

  • Can IIS admin change password of Windows Service account

    - by sweta Jha
    We have a service account defined for anonymous access which is used for several web sites hosted on the web server. This account has access to several network resources like report server, file servers and so on. While deploying a new web site, we used the same service account for anonymous access. IIS takes the username/password for the account and then a dialog opens for confirm password. Accidently, we gave a wrong password in both the text boxes, the new site with wrong password is working fine but all other previously hosted sites which were using the service account, started giving the unautorized access error. Is it possible that when we entered wrong password for the new web site, the password of the account got reset and all sites stopped functioning?

  • confusion about transactions and msdtc

    - by muhan
    I have some basic confusion about how transactions and msdtc work together. I have a basic server/client winforms app. The app uses transactionscope to encapsulate several sql commands that are executed on the sql server. The app seemed to work fine when I enabled msdtc network access on the server only. Then one day it stopped working saying network access was not enabled. Now it seems that I have to enable msdtc network access on both the client computer and server for transactionscope to work. Does the client or server msdtc service do the transaction work? Or maybe its both? Does anyone have guidance on whether msdtc network access is needed on both client and server or just server?

  • How to write mmap input memory to O_DIRECT output file?

    - by Friedrich
    why doesn't following pseudo-code work (O_DIRECT results in EFAULT) in_fd = open("/dev/mem"); in_mmap = mmap(in_fd); out_fd = open("/tmp/file", O_DIRECT); write(out_fd, in_mmap, PAGE_SIZE); while following does (no O_DIRECT) in_fd = open("/dev/mem"); in_mmap = mmap(in_fd); out_fd = open("/tmp/file"); write(out_fd, in_mmap, PAGE_SIZE); I guess it's something with virtual kernel pages to virtual user pages, which cannot be translated in the write call? Best regards, Friedrich

There is any real example to use IMAGE?

  • Isolated storage misunderstand

    - by Costa
    Hi this is a discussion between me and me to understand isolated storage issue. can you help me to convince me about isolated storage!! This is a code written in windows form app (reader) that read the isolated storage of another win form app (writer) which is signed. where is the security if the reader can read the writer's file, I thought only signed code can access the file! If all .Net applications born equal and have all permissions to access Isolated storage, where is the security then? If I can install and run Exe from isolated storage, why I don't install a virus and run it, I am trusted to access this area. but the virus or what ever will not be trusted to access the rest of file system, it only can access the memory, and this is dangerous enough. I cannot see any difference between using app data folder to save the state and using isolated storage except a long nasty path!! I want to try give low trust to Reader code and retest, but they said "Isolated storage is actually created for giving low trusted application the right to save its state". Reader code: private void button1_Click(object sender, EventArgs e) { String path = @"C:\Documents and Settings\All Users\Application Data\IsolatedStorage\efv5cmbz.ewt\2ehuny0c.qvv\StrongName.5v3airc2lkv0onfrhsm2h3uiio35oarw\AssemFiles\toto12\ABC.txt"; StreamReader reader = new StreamReader(path); var test = reader.ReadLine(); reader.Close(); } Writer: private void button1_Click(object sender, EventArgs e) { IsolatedStorageFile isolatedFile = IsolatedStorageFile.GetMachineStoreForAssembly(); isolatedFile.CreateDirectory("toto12"); IsolatedStorageFileStream isolatedStorage = new IsolatedStorageFileStream(@"toto12\ABC.txt", System.IO.FileMode.Create, isolatedFile); StreamWriter writer = new StreamWriter(isolatedStorage); writer.WriteLine("Ana 2akol we ashrab kai a3eesh wa akbora"); writer.Close(); writer.Dispose(); }

  • Selenium RC: how to capture/handle error?

    - by KenBurnsFan1
    Hi, My test uses Selenium to loop through a CSV list of URLs via an HTTP proxy (working script below). As I watch the script run I can see about 10% of the calls produce "Proxy error: 502" ("Bad_Gateway"); however, the errors are not captured by my catch-all "except Exception" clause -- ie: instead of writing 'error' in the appropriate row of the "output.csv", they get passed to the else clause and produce a short piece of html that starts: "Proxy error: 502 Read from server failed: Unknown error." Also, if I collect all the URLs which returned 502s and re-run the script, they all pass, which leads me to believe that this is a sporadic network path issue. Question: Can the script be made to recognize the the 502 errors, sleep a minute, and then retry the URL instead of moving on to the next URL in the list? The only alternative that I can think of is to apply re.search("Proxy error: 502") after "get_html_source" as a way to catch the bad calls. Then, if the RE matches, put the script to sleep for a minute and then retry 'sel.open(row[0]' on the URL which produced the 502. Any advice would be much appreciated. Thanks! #python 2.6 from selenium import selenium import unittest, time, re, csv, logging class Untitled(unittest.TestCase): def setUp(self): self.verificationErrors = [] self.selenium = selenium("localhost", 4444, "*firefox", "http://baseDomain.com") self.selenium.start() self.selenium.set_timeout("60000") def test_untitled(self): sel = self.selenium spamReader = csv.reader(open('ListOfSubDomains.csv', 'rb')) for row in spamReader: try: sel.open(row[0]) except Exception: ofile = open('output.csv', 'ab') ofile.write("error" + '\n') ofile.close() else: time.sleep(5) html = sel.get_html_source() ofile = open('output.csv', 'ab') ofile.write(html.encode('utf-8') + '\n') ofile.close() def tearDown(self): self.selenium.stop() self.assertEqual([], self.verificationErrors) if __name__ == "__main__": unittest.main()

  • Using Google AppEngine app as a OAuth provider

    - by Alistair
    Hi, I'm using the Google AppEngine 1.3.4 SDK which offers to allow your application to act as a OAuth service provider (http://code.google.com/appengine/docs/python/oauth/). Setting up a standard application on my localhost and using the following: Request URL /_ah/OAuthGetRequestToken Authorize URL /_ah/OAuthAuthorizeToken Access Token URL /_ah/OAuthGetAccessToken The client application just gets sent to a page requesting to grant OAuth access even though no user is logged in. Clicking 'Grant access' results in a message saying 'OAuth access granted' with no tokens or anything exchange. Can't see how this could work when it's not even prompting for a login. As this functionality is quite new I can't find much out there. I've created a OAuth provider before in Rails and know that you need a Consumer Key and Secret, something that seems to be lacking in GAE? Any ideas on how to get OAuth working in a sample GAE project are most welcome.

  • Broken pipe error in rails with memcached

    - by abronte
    I keep running into this error MemCacheError (Broken pipe): Broken pipe on my Rails app and I can't figure out why. When I access memcached via Rails.cache in my controller, the first 1 or 2 read/writes always seems to throw the broken pipe error. But when I access memcached by creating a new object, ActiveSupport::Cache::MemCacheStore.new, I don't seem to get this error. I also access memcached in another ruby process, and the first read always has this error regardless of the way I access memcached. I did implement a work around just by retrying the read but id rather have a better long term solution. Currently the only time I see this problem is after I restart memcached. I'm using Rails 2.3.5 and memcached 1.4.4 (I've also tried this with memcached 1.2.2).

  • Accessing SQL Server using an IP Address and Port Number ... Help!

    - by Mike
    I need to access an SQL Server that is on a machine behind a firewall and you access this machine using an ip address like 95.95.95.33:6930 (not the real ip address) ... But, you get my point that by accessing 95.95.95.33 on port 6930, the firewall routes the requests to that particular machine ... My question is ... How do you construct a connection string to access the machine at address 95.95.95.33:6930 and then further access the SQL Server on port 1433 or maybe a different port like 8484 ??? Thanks Mike

  • [JS] XMLHttpRequest problem

    - by mcco
    I am trying to do "POST" with XMLHttpRequest in a firefox extension, and after that I try to get the "Location" header and open it in a new tab. For some reason, the XMLHttpRequest doesn't contain a location header. My code function web(url,request) { var http = new XMLHttpRequest(); http.open('POST',url,true); http.setRequestHeader('Content-Type','application/x-www-form-urlencoded'); http.onreadystatechange=function() { if(http.readyState == 2) { alert(http.getResponseHeader("Location")); } } http.send(request); } Also, if I change the alert to getAllResponseHeaders() to see all headers, I just don't see the location header there. If I try to spy on the request of the original site with Firebug, it does show me the location header in the response. Please help me resolve my issues. Thanks :) P.S. I'm also unable to open a link in new tab using window.open(url, this.window.title);, but as that's not directly related to the rest of this I'll post a separate question to ask about it.

After input dthe calculating module should start and do its job. The result is again imported in Ms Access. However we work wit dBase files (.dbf) as datafiles.

It will start-up when called from the Access module, but then generates errors or at least does not write correct results to a datatable. We cannot find the reason for this beheavior.

  • accessing parsed JSON on the iPhone SDK

    - by itai alter
    Hello All! I've been following the great tutorial about (iPhone, json and Flickr API and I did manage to access the parsed json info just fine. Now I'm trying to do the same thing with the Twitter API, and I am able to get the json info and parse it, but I can't seem to access it like in Flickr. I noticed that the json info that is retrieved from Twitter is a little different from Flickr. The Flickr json info starts straight with a curly braces ({), while the Twitter json info starts with a square bracket and then a curly braces ([{). I understand that it means it's an array inside the json info, but I don't know how to access it. In the Flickr example, I access the objects like so (the second line takes the number of pages Flickr has reported): NSDictionary *results = [jsonString JSONValue]; pagesString = [[results objectForKey:@"photos"] objectForKey:@"pages"]; but I can't seem to access the Twitter response in the same way... Does anyone know of a solution? (here's an example of the Twitter JSON response: api.twitter.com/1/statuses/public_timeline.json ) Thanks a bunch!

  • Cookie won't unset

    - by Jordan Satok
    OK, I'm stumped, and have been staring at this for hours. I'm setting a cookie at /access/login.php with the following code: setcookie('username', $username, time() + 604800, '/'); When I try to logout, which is located at /access/logout.php (and rewritten to /access/logout), the cookie won't seem to unset. I've tried the following: setcookie('username', false, time()-3600, '/'); setcookie('username', '', time()-3600, '/'); setcookie('username', '', 1, '/'); I've also tried to directly hit /access/logout.php, but it's not working. Nothing shows up in the php logs. Any suggestions? I'm not sure if I'm missing something, or what's going on, but it's been hours of staring at this code and trying to debug.
