  • Htaccess Rewrite Rule

    - by Marcx
    Hi, I'm getting crazy with htaccess and rewrite rule.. I'd like to understand how it works, I hate it, anyway here's my problem (really simple for most of you) My site has one main page index.php. This is the only page, all the others are handled by this one. I did a simple RewriteRule RewriteRule ^([a-zA-Z0-9_-]+)$ index.php?page=$1 to do this: http://www.me.ext/index.php?page=VAL - http://www.me.ext/VAL but I don't know how create a rule for this http://www.me.ext/index.php?page=VAL&var1=VAL2&var2=VAL3 etc. I'd like a final url like: http://www.me.ext/VAL/VAL2/VAL3 etc. Thanks

  • How does real world login process happen in web application in Java?

    - by Nitesh Panchal
    Hello, I am very much confused regarding login process that happen in Java web application. I read many tutorials regarding jdbcRealm and JAAS. But, one thing that i don't understand is that why should i use them ? Can't i simply check directly against my database of users? and once they successfully login to the site, i store some variable in session as a flag. And probably check that session variable on all restricted pages (I mean keep a filter for restricted resources url pattern).If the flag doesn't exist simply redirect the user to login page. Is this approach correct?Does this approch sound correct? If yes, then why did all this JAAS and jdbcRealm came into existence? Secondly, I am trying to completely implement SAS(Software as service) in my web application, meaning everything is done through web services.If i use webservices, is it possible to use jdbcRealm? If not, then is it possible to use JAAS? If yes, then please show me some example which uses mySql as a database and then authenticates and authorizes. I even heard about Spring Security. But, i am confused about that too in the sense that how do i use webservice with Spring Security. Please help me. I am really very confused. I read sun's tutorials but they only keep talking about theories. For programmers to understand a simple concept, they show a 100 page theory first before they finally come to one example.

  • Lua class instance with nested tables

    - by Anonnobody
    Hello, Simple lua game with simple class like so: creature = class({ name = "MONSTER BADDY!", stats = { power = 10, agility = 10, endurance = 10, filters = {} }, other_things = ... }) creatureA = creature.new() creatureB = creature.new() creatureA.name = "Frank" creatureB.name = "Zappa" creatureA.stats.agility = 20 creatureB.stats.power = 12 -- blah blah blah Non table values are individual to each instance, but table values are shared among all instances and if I modify a stats.X value in one instance, all other instances see the same stats table. Q1: Is my OO implementation flawed? I tried LOOP and the same result occured, is there a fundamental flaw in my logic? Q2: How would you have each instance of creature have it's own stats table (and sub tables)? PS. I cannot flatten my class table as it's a bit more complicated than the example and other parts of the code are simplified with this nested table implementation. Thanks a bunch.

  • Python: using a regular expression to match one line of HTML

    - by skylarking
    This simple Python method I put together just checks to see if Tomcat is running on one of our servers. import urllib2 import re import sys def tomcat_check(): tomcat_status = urllib2.urlopen('http://10.1.1.20:7880') results = tomcat_status.read() pattern = re.compile('<body>Tomcat is running...</body>',re.M|re.DOTALL) q = pattern.search(results) if q == []: notify_us() else: print ("Tomcat appears to be running") sys.exit() If this line is not found : <body>Tomcat is running...</body> It calls : notify_us() Which uses SMTP to send an email message to myself and another admin that Tomcat is no longer runnning on the server... I have not used the re module in Python before...so I am assuming there is a better way to do this... I am also open to a more graceful solution with Beautiful Soup ... but haven't used that either.. Just trying to keep this as simple as possible...

  • Javascript: replacing newlines with <br/> working in FF and SAFARI and not working in IE

    - by Daniel
    I was thinking that replacing \n with with javascript was quite a simple task, but it seems not to be so. Posts in Ask Ben or StackOverflow suggest that something as simple as: dst= dst.replace (/\n/g, "<br/>"); $("div.descr").html(dst); will get the job done. Indeed, this work in FF and Safari but not in IE. Text has been created in a textarea and then stored in a database, then retrieved without further processing. It works using FF on windows and Safari on Mac. IE on windows, nada. Is it a major bug in my head? Is it a JQuery issue? Have some idea about how to solve this? And possible reason for? Many thanks

  • Caching Authentication Data

    - by PartlyCloudy
    Hi, I'm currently implementing a REST web service using CouchDB and RESTlet. The RESTlet layer is mainly for authentication and some minor filtering of the JSON data served by CouchDB: Clients <= HTTP = [ RESTlet <= HTTP = CouchDB ] I'm using CouchDB also to store user login data, because I don't want to add an additional database server for that purpose. Thus, each request to my service causes two CouchDB requests conducted by RESTlet (auth data + "real" request). In order to keep the service as efficent as possible, I want to reduce the number of requests, in this case redundant requests for login data. My idea now is to provide a cache (i.e.LRU-Cache via LinkedHashMap) within my RESTlet application that caches login data, because HTTP caching will probabily not be enough. But how do I invalidate the cache data, once a user changes the password, for instance. Thanks to REST, the application might run on several servers in parallel, and I don't want to create a central instance just to cache login data. Currently, I save requested auth data in the cache and try to auth new requests by using them. If a authentication fails or there is now entry available, I'll dispatch a GET request to my CouchDB storage in order to obtain the actual auth data. So in a worst case, users that have changed their data will perhaps still be able to login with their old credentials. How can I deal with that? Or what is a good strategy to keep the cache(s) up-to-date in general? Thanks in advance.

  • Set property on usercontrol that can be used in custom panel in control... Silverlight

    - by Dimestore Cowboy
    I have a simple usercontrol that uses a simple custom panel where I just overrode the Orientation and Measure functions. What I want to do is to have a property in the usercontol to control the orientation So I basicaly have UserControl -- Listbox -- MyPanel And I want a property for the usercontrol that can be set in xaml (of type System.Windows.Controls.Orientation ) that I can bind to from my custom panel (or a different approach if binding isnt the right way to do it) It would be a bonus if that property could show up in the properties window and you could select vertical or horizontal. And a super bonus if I could change the property at design time and have the listbox/

  • a4j:support within a rich:modalPanel

    - by Andy Deighton
    Hi all, I've hit a wall. I know the a4j and rich tags pretty well (I use Seam 2.2.0 and Richfaces 3.3.1). However, I'm trying to do something quite simple, but in a rich:modalPanel. It seems that rich:modalPanels do not allow Ajax events to be fired. Here's a simple breakdown: I have a h:selectOneMenu with some items in it and whose value is attached to a backing bean. Attached to that h:selectOneMenu is a a4j:support tag so that whenever the change event is fired, the backing bean should get updated. Truly simple stuff eh? However, when this h:selectOneMenu is in a rich:modalPanel the onchange event doesn't update the backing bean until the rich:modalPanel closes. I can confirm this because I'm running it in Eclipse debug mode and I have a breakpoint on the setter of the property that's hooked up to the h:selectOneMenu. This is driving me mad! This is vanilla stuff for Ajax, but rich:modalPanels don't seem to allow it. So, the question is: can I do Ajax stuff within a rich:modalPanel? I'm basically trying to use the rich:modalPanel as a form (I've tried a4j:form and h:form to no avail) that reacts to changes to the drop down (e.g. when the user changes the drop down, a certain part of the form should get reRendered). Am I trying to do something that's not possible? Here's a simplified version of the modalPanel: <rich:modalPanel id="quickAddPanel"> <div> <a4j:form id="quickAddPaymentForm" ajaxSubmit="true"> <s:decorate id="paymentTypeDecorator"> <a4j:region> <h:selectOneMenu id="paymentType" required="true" value="#{backingBean.paymentType}" tabindex="1"> <s:selectItems label="#{type.description}" noSelectionLabel="Please select..." value="#{incomingPaymentTypes}" var="type"/> <s:convertEnum/> <a4j:support ajaxSingle="true" event="onchange" eventsQueue="paymentQueue" immediate="true" limitToList="true" reRender="paymentTypeDecorator, paymentDetailsOutputPanel, quickAddPaymentForm"/> </h:selectOneMenu> </a4j:region> </s:decorate> </fieldset> <fieldset class="standard-form"> <div class="form-title">Payment details</div> <a4j:outputPanel id="paymentDetailsOutputPanel"> <h:outputText value="This should change whenever dropdown changes: #{backingBean.paymentType}"/> </a4j:outputPanel> </fieldset> </a4j:form> </div> </rich:modalPanel> Regards, Andy

  • How to make Web Storage persistent in Cordova using JS?

    - by ett
    I have a small quiz app, which is a cross-platform mobile app, that I plan for it to run on Android, iOS, and WP8. I want to store a local highscore, where it will keep track how many points the user had, and if he/she does better than the already stored highscore, update the current highscore. Though, I want the highscore to be persistent, what I mean is, every time the user opens the app I want the last highscore to be present and it to be compared with the new quiz score. Meaning, I don't want the highscore to be deleted after each time the app is closed. I also want for the first time when the app is ran, the highscore to be set to 0, so obviously the first time the user finishes the quiz gets a new highscore. I have those codes so far: scoredb.js // Wait for device API libraries to load document.addEventListener("deviceready", initScoreDB, false); // Device APIs are available function initScoreDB() { window.localStorage.setItem("score", 0); highscore = window.localStorage.getItem("score"); } main.js var correct = 0; var highscore; // In between I have some code that keeps incrementing // correct variable for each correct answer. if (correct > highscore) { window.localStorage.setItem("score", correct); highscore = correct; } It does seem to work okay once the app is started. I did the quiz three times, in the simulator, and it keeps the score as it should. Though, each time I open the app, highscore is reseted to 0. I guess it is due to the fact that I call initScoreDB when the device is ready, and I initialize the score to 0 there and give that value to highscore. Can someone help me to initialize the score to 0 only when the app is ran for the first time, and all the other times to keep the latest highscore as the current highscore and compare it each time with the score that is achieved when the quiz is finished. If someone can help me, I would be glad.

  • accessing a value of a nested hash

    Hello! I am new to perl and I have a problem that's very simple but I cannot find the answer when consulting my perl book. When printing the result of Dumper($request); I get the following result: $VAR1 = bless( { '_protocol' => 'HTTP/1.1', '_content' => '', '_uri' => bless( do{\(my $o = 'http://myawesomeserver.org:8081/counter/')}, 'URI::http' ), '_headers' => bless( { 'user-agent' => 'Mozilla/5.0 (X11; U; Linux i686; en; rv:1.9.0.4) Gecko/20080528 Epiphany/2.22 Firefox/3.0', 'connection' => 'keep-alive', 'cache-control' => 'max-age=0', 'keep-alive' => '300', 'accept' => 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8', 'accept-language' => 'en-us,en;q=0.5', 'accept-encoding' => 'gzip,deflate', 'host' => 'localhost:8081', 'accept-charset' => 'ISO-8859-1,utf-8;q=0.7,*;q=0.7' }, 'HTTP::Headers' ), '_method' => 'GET', '_handle' => bless( \*Symbol::GEN0, 'FileHandle' ) }, 'HTTP::Server::Simple::Dispatched::Request' ); How can I access the values of '_method' ('GET') or of 'host' ('localhost:8081'). I know that's an easy question, but perl is somewhat cryptic at the beginning. Thank you, St.

  • Should a Unit-test replicate functionality or Test output?

    - by Daniel Beardsley
    I've run into this dilemma several times. Should my unit-tests duplicate the functionality of the method they are testing to verify it's integrity? OR Should unit tests strive to test the method with numerous manually created instances of inputs and expected outputs? I'm mainly asking the question for situations where the method you are testing is reasonably simple and it's proper operation can be verified by glancing at the code for a minute. Simplified example (in ruby): def concat_strings(str1, str2) return str1 + " AND " + str2 end Simplified functionality-replicating test for the above method: def test_concat_strings 10.times do str1 = random_string_generator str2 = random_string_generator assert_equal (str1 + " AND " + str2), concat_strings(str1, str2) end end I understand that most times the method you are testing won't be simple enough to justify doing it this way. But my question remains; is this a valid methodology in some circumstances (why or why not)?

  • LNK2001: What have I forgotton to set?

    - by graham.reeds
    Following on from my previous question regarding debugging of native code, I decided to create a simple test from a console app as I wasn't getting anywhere with debugging the service directly. So I created a vc6 console app, added the dll project to the workspace and ran it. Instead of executing as expected it spat out the following linker errors: main.obj : error LNK2001: unresolved external symbol "int __stdcall hmDocumentLAdd(char *,char *,long,char *,char *,long,long,long,long *)" (?hmDocumentLAdd@@YGHPAD0J00JJJPAJ@Z) main.obj : error LNK2001: unresolved external symbol "int __stdcall hmGetDocBasePath(char *,long)" (?hmGetDocBasePath@@YGHPADJ@Z) Debug/HazManTest.exe : fatal error LNK1120: 2 unresolved externals This seems to be a simple case of forgetting something in the linker options: However everything seems to be normal, and the lib file, dll and source is available. If I change the lib file to load to nonsense it kicks up the fatal error LNK1104: cannot open file "asdf.lib", so that isn't a problem. I have previously linked to dll and they have just worked, so what I have forgotton to do?

  • Should the PHP community start using more discriptive Exceptions?

    - by fireeyedboy
    I work with Zend Framework a lot and I just took a peek at Kohana, and it strikes me as odd that this is a typical scenario in these frameworks: throw Some_Componenents_Exception( 'invalid argument' ); Where I believe this wouldn't be mouch more useful: throw Some_Components_InvalidArgumentException( 'whatever discription' ); Because it is easier to catch. I suspect, but immediately admit it's prejudiced, that the former practice is common in the PHP community. Should we, the PHP community, start using these descriptive types of expections more?

  • Why always fires OnFailure when return View() to Ajax Form ?

    - by Wahid Bitar
    I'm trying to make a log-in log-off with Ajax supported. I made some logic in my controller to sign the user in and then return simple partial containing welcome message and log-Off ActionLink my Action method looks like this : public ActionResult LogOn(LogOnModel model, string returnUrl) { if (ModelState.IsValid) { if (MembershipService.ValidateUser(model.UserName, model.Password)) { FormsService.SignIn(model.UserName, model.RememberMe); if (Request.IsAjaxRequest()) { //HERE IS THE PROBLEM :( return View("LogedInForm"); } else { if (!String.IsNullOrEmpty(returnUrl)) return Redirect(returnUrl); else return RedirectToAction("Index", "Home"); } } else { ModelState.AddModelError("", "The user name or password provided is incorrect."); if (Request.IsAjaxRequest()) { return Content("There were an error !"); } } } return View(model); } and I'm trying to return this simple partial : Welcome <b><%= Html.Encode(Model.UserName)%></b>! <%= Html.ActionLink("Log Off", "LogOff", "Account") %> and of-course the two partial are strongly-typed to LogOnModel. But if i returned View("PartialName") i always get OnFailure with status code 500. While if i returned Content("My Message") everything is going right. so please tell me why i always get this "StatusCode = 500" ??. where is the big mistake ??. By the way in my Site MasterPage i rendered partial to show long-on simple form this partial looks like this : <script type="text/javascript"> function ShowErrorMessage(ajaxContext) { var response = ajaxContext.get_response(); var statusCode = response.get_statusCode(); alert("Sorry, the request failed with status code " + statusCode); } function ShowSuccessMessage() { alert("Hey everything is OK!"); } </script> <div id="logedInDiv"> </div> <% using (Ajax.BeginForm("LogOn", "Account", new AjaxOptions { UpdateTargetId = "logedInDiv", InsertionMode = InsertionMode.Replace, OnSuccess = "ShowSuccessMessage", OnFailure = "ShowErrorMessage" })) { %> <%= Html.TextBoxFor(m => m.UserName)%> <%= Html.PasswordFor(m => m.Password)%> <%= Html.CheckBoxFor(m => m.RememberMe)%> <input type="submit" value="Log On" /> < <% } %>

  • SQLAlchemy - how to map against a read-only (or calculated) property

    - by Jeff Peck
    I'm trying to figure out how to map against a simple read-only property and have that property fire when I save to the database. A contrived example should make this more clear. First, a simple table: meta = MetaData() foo_table = Table('foo', meta, Column('id', String(3), primary_key=True), Column('description', String(64), nullable=False), Column('calculated_value', Integer, nullable=False), ) What I want to do is set up a class with a read-only property that will insert into the calculated_value column for me when I call session.commit()... import datetime def Foo(object): def __init__(self, id, description): self.id = id self.description = description @property def calculated_value(self): self._calculated_value = datetime.datetime.now().second + 10 return self._calculated_value According to the sqlalchemy docs, I think I am supposed to map this like so: mapper(Foo, foo_table, properties = { 'calculated_value' : synonym('_calculated_value', map_column=True) }) The problem with this is that _calculated_value is None until you access the calculated_value property. It appears that SQLAlchemy is not calling the property on insertion into the database, so I'm getting a None value instead. What is the correct way to map this so that the result of the "calculated_value" property is inserted into the foo table's "calculated_value" column?

  • Send Keyboard Events from one Form to another Form

    - by thalm
    Hello, my question is quite simple: Our C# application has one MainForm with a menu and several keyboard shortcuts associated with the menu entries. Now we need to trigger the menu entries from some child forms too. But since the MainForm is inactive when one of the child forms is active, the shortcuts do not work. Is there a simple way to propagate all keyboard events from the child form to the 'Owner' form? Or just to another form in general? Ah, and we cannot use some low level windows stuff, because we need to run the application on Mono/Linux too.
