"Permission denied" & 500 Internal Server error serving PHP in Mac OS X

- by Abhic

I just set up Web Sharing in Mac OS X 10.6.2 Snow Leopard. My httpd.conf allows for ExecCGI and all the folders and files are readable by everybody and even writable by me. I put a simple Hello World in index.php in my base site and yet my apache error log shows this: [Thu Mar 18 00:17:18 2010] [error] [client 192.168.11.135] (13)Permission denied: exec of '/Users/abhic/Sites/index.php' failed [Thu Mar 18 00:17:18 2010] [error] [client 192.168.11.135] Premature end of script headers: index.php <html> <head> <title> Hello </title> </head> <body> <?php echo "Hello"; ?> </body> </html> is what my index.php looks like placed in /Users/abhic/Sites My browser shows a 500 Internal Server Error Any help would do me good in the middle of the night. I have been trying to solve this for way too long. Thank you.

Very, very simple asp.net page takes forever to load

- by John Hoge

I've got a page that couldn't be more simple: <%@ Page Trace="true" %> <html> <head></head> <body> <h1>Hello World</h1> <a href="/OtherPage.aspx"/>Other Page</a> <p><%=DateTime.Now.ToString()%> </body> </html> ... but it takes forever to load. There is no database or web service call to slow it down. The trace command reveals that the time from Begin PreInot to End Render is .000049 seconds, but the page itself takes several seconds to load. It is a new web site I just created for this test, and just has a web.config & two test files. The only thing in the web.config is access control: <authorization><allow users="domain\me" /><deny users = "*"/></authorization> What else could IIS be doing with all of that time?

Memory leak involving jQuery Ajax requests

- by Eli Courtwright

I have a webpage that's leaking memory in both IE8 and Firefox; the memory usage displayed in the Windows Process Explorer just keeps growing over time. The following page requests the "unplanned.json" url, which is a static file that never changes (though I do set my Cache-control HTTP header to no-cache to make sure that the Ajax request always goes through). When it gets the results, it clears out an HTML table, loops over the json array it got back from the server, and dynamically adds a row to an HTML table for each entry in the array. Then it waits 2 seconds and repeats this process. Here's the entire webpage: <html> <head> <title>Test Page</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script> </head> <body> <script type="text/javascript"> function kickoff() { $.getJSON("unplanned.json", resetTable); } function resetTable(rows) { $("#content tbody").empty(); for(var i=0; i<rows.length; i++) { $("<tr>" + "<td>" + rows[i].mpe_name + "</td>" + "<td>" + rows[i].bin + "</td>" + "<td>" + rows[i].request_time + "</td>" + "<td>" + rows[i].filtered_delta + "</td>" + "<td>" + rows[i].failed_delta + "</td>" + "</tr>").appendTo("#content tbody"); } setTimeout(kickoff, 2000); } $(kickoff); </script> <table id="content" border="1" style="width:100% ; text-align:center"> <thead><tr> <th>MPE</th> <th>Bin</th> <th>When</th> <th>Filtered</th> <th>Failed</th> </tr></thead> <tbody></tbody> </table> </body> </html> If it helps, here's an example of the json I'm sending back (it's this exact array wuith thousands of entries instead of just one): [ { mpe_name: "DBOSS-995", request_time: "09/18/2009 11:51:06", bin: 4, filtered_delta: 1, failed_delta: 1 } ] EDIT: I've accepted Toran's extremely helpful answer, but I feel I should post some additional code, since his removefromdom jQuery plugin has some limitations: It only removes individual elements. So you can't give it a query like `$("#content tbody tr")` and expect it to remove all of the elements you've specified. Any element that you remove with it must have an `id` attribute. So if I want to remove my `tbody`, then I must assign an `id` to my `tbody` tag or else it will give an error. It removes the element itself and all of its descendants, so if you simply want to empty that element then you'll have to re-create it afterwards (or modify the plugin to empty instead of remove). So here's my page above modified to use Toran's plugin. For the sake of simplicity I didn't apply any of the general performance advice offered by Peter. Here's the page which now no longer memory leaks: <html> <head> <title>Test Page</title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script> </head> <body> <script type="text/javascript">  </script> <div id="message" style="color:red"></div> <table id="content" border="1" style="width:100% ; text-align:center"> <thead><tr> <th>MPE</th> <th>Bin</th> <th>When</th> <th>Filtered</th> <th>Failed</th> </tr></thead> <tbody id="id_field_required"></tbody> </table> </body> </html> FURTHER EDIT: I'll leave my question unchanged, though it's worth noting that this memory leak has nothing to do with Ajax. In fact, the following code would memory leak just the same and be just as easily solved with Toran's removefromdom jQuery plugin: function resetTable() { $("#content tbody").empty(); for(var i=0; i<1000; i++) { $("#content tbody").append("<tr><td>" + "DBOSS-095" + "</td>" + "<td>" + 4 + "</td>" + "<td>" + "09/18/2009 11:51:06" + "</td>" + "<td>" + 1 + "</td>" + "<td>" + 1 + "</td></tr>"); } setTimeout(resetTable, 2000); } $(resetTable);

How to implement Survey page using ASP.NET MVC?

- by Aleks

I need to implement the survey page using ASP.NET MVC (v.4) That functionality has already been implemented in our project using ASP.NET WebForms. (I really searched a lot for real examples of similar functionality implemented via MVC, but failed) Goal: staying on the same page (in webforms -'Survey.aspx') each time user clicks 'Next Page', load next bunch of questions (controls) which user is going to answer. Type of controls in questions are defined only in run-time (retrieved from Data Base). To explain better the question I manually created (rather simple) mark-up below of 'two' pages (two loads of controls): <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Survey.aspx.cs" Inherits="WebSite.Survey" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div><h2>Internal Survey</h2></div> <div><h3>Page 1</h3></div> <div style="padding-bottom: 10px"><div><b>Did you have internet disconnections during last week?</b></div> <asp:RadioButtonList ID="RadioButtonList1" runat="server"> <asp:ListItem>Yes</asp:ListItem> <asp:ListItem>No</asp:ListItem> </asp:RadioButtonList> </div> <div style="padding-bottom: 10px"><div><b>Which days of the week suit you best for meeting up ?</b></div> <asp:CheckBoxList ID="CheckBoxList1" runat="server"> <asp:ListItem>Monday</asp:ListItem> <asp:ListItem>Tuesday</asp:ListItem> <asp:ListItem>Wednesday</asp:ListItem> <asp:ListItem>Thursday</asp:ListItem> <asp:ListItem>Friday</asp:ListItem> </asp:CheckBoxList> </div> <div style="padding-bottom: 10px"> <div><b>How satisfied are you with your job? </b></div> <asp:RadioButtonList ID="RadioButtonList2" runat="server"> <asp:ListItem>Very Good</asp:ListItem> <asp:ListItem>Good</asp:ListItem> <asp:ListItem>Bad</asp:ListItem> <asp:ListItem>Very Bad</asp:ListItem> </asp:RadioButtonList> </div> <div style="padding-bottom: 10px"> <div><b>How satisfied are you with your direct supervisor ? </b></div> <asp:RadioButtonList ID="RadioButtonList3" runat="server"> <asp:ListItem>Not Satisfied</asp:ListItem> <asp:ListItem>Somewhat Satisfied</asp:ListItem> <asp:ListItem>Neutral</asp:ListItem> <asp:ListItem>Satisfied</asp:ListItem> <asp:ListItem>Very Satisfied</asp:ListItem> </asp:RadioButtonList> </div> <div style="padding-bottom: 10px"> <asp:Button ID="Button1" runat="server" Text="Next Page" onclick="Button1_Click" /> </div> </form> </body> </html> PAGE 2 <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Survey.aspx.cs" Inherits="WebSite.Survey" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div><h2>Internal Survey</h2></div> <div><h3>Page 2</h3></div> <div style="padding-bottom: 10px"><div><b>Did admininstators fix your internet connection in time ?</b></div> <asp:RadioButtonList ID="RadioButtonList1" runat="server"> <asp:ListItem>Yes</asp:ListItem> <asp:ListItem>No</asp:ListItem> </asp:RadioButtonList> </div> <div style="padding-bottom: 10px"><div><b>What's your overal impression about the job ?</b></div> <asp:TextBox ID="TextBox1" runat="server" Height="88px" Width="322px"></asp:TextBox> </div> <div style="padding-bottom: 10px"> <div><b>Select day which best suits you for admin support ? </b></div> <asp:DropDownList ID="DropDownList1" runat="server"> <asp:ListItem>Select day</asp:ListItem> <asp:ListItem>Monday</asp:ListItem> <asp:ListItem>Wednesday</asp:ListItem> <asp:ListItem>Friday</asp:ListItem> </asp:DropDownList> </div> <div style="padding-bottom: 10px"> <asp:Button ID="Button1" runat="server" Text="Next Page" onclick="Button1_Click" /> </div> </form> </body> </html>

problem with tinymce textarea in dynamically added jquery tabs

- by kranthi

I have an aspx page(Default1.aspx),in which i have a static jquery tab and anchor tag upon clicking the anchor tag(Add Tab) I am adding new tab dynamically,which gets its contents loaded from another aspx page(Default2.aspx).This second page contains some text inside a tag,a textarea with 'tinymce' class which is placed inside a div with 'style="display:none" ' and this textarea gets displayed only upon clicking the edit button on that page. The HTML of Default1.aspx page looks like this. <head runat="server"> <title>Untitled Page</title> <script src="js/jquery-1.3.2.min.js" type="text/javascript"></script> <script src="js/jquery-ui-1.7.2.custom.min.js" type="text/javascript"></script> <link href="css/custom-theme/jquery-ui-1.7.2.custom.css" rel="stylesheet" type="text/css" /> <link href="css/widgets.css" rel="stylesheet" type="text/css" /> <link href="css/print.css" rel="stylesheet" type="text/css" /> <link href="css/reset.css" rel="stylesheet" type="text/css" /> <script type="text/javascript" src="js/tiny_mce/jquery.tinymce.js"></script> <script type="text/javascript"> $(function() { //DECLARE FUNCTION: removetab var removetab = function(tabselector, index) { $(".removetab").click(function(){ $(tabselector).tabs('remove',index); }); }; //create tabs $("#tabs").tabs({ add: function(event, ui) { //select newely opened tab $(this).tabs('select',ui.index); //load function to close tab removetab($(this), ui.index); }, show: function(event, ui) { if($.fn.tinymce) { $('textarea.tinymce').tinymce({ // Location of TinyMCE script script_url : 'js/tiny_mce/tiny_mce.js', // General options theme : "advanced", plugins : "safari,style,layer,table,advhr,advimage,advlink,inlinepopups,insertdatetime,preview,media,searchreplace,print,contextmenu,paste,directionality,fullscreen,noneditable,visualchars,nonbreaking,xhtmlxtras,template", // Theme options theme_advanced_buttons1 : "bold,italic,underline,strikethrough,|,bullist,numlist,|,justifyleft,justifycenter,justifyright,justifyfull,styleselect,formatselect,fontselect,fontsizeselect", theme_advanced_buttons2 : "outdent,indent,blockquote,|,undo,redo,|,link,unlink,anchor,image,cleanup,help,code,|,insertdate,inserttime,preview,|,forecolor,backcolor", theme_advanced_buttons3 : "sub,sup,|,ltr,rtl,|,fullscreen", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left" /*theme_advanced_statusbar_location : "bottom",*/ /*theme_advanced_resizing : true,*/ }); } //load function to close selected tabs removetab($(this), ui.index); } }); //load new tab $(".addtab").click(function(){ var href=$(this).attr("href"); var title=$(this).attr("title"); $("#tabs").tabs( 'add' , href , title+' <span class="removetab ui-icon ui-icon-circle-close" style="float:right; margin: -2px -10px 0px 3px; cursor:pointer;"></span>'); return false; }); }); function showEditFields(){ $('.edit').css('display','inline'); } </script> </head> <body> <form id="form1" runat="server"> <div> <a class="addtab" title="Tab Label" href="HTMLPage.htm">Add Tab</a> <div id="tabs"> <ul> <li><a href="#tabs-1">Default Tab</a></li> </ul> <div id="tabs-1"> <p>Etiam aliquet massa et lorem.

Could someone please help me with this? Thanks.

calling and killing a parent function with onmouseover and onmouseout events

I want to call the function upon the onmouseover="ParentFunction();" then kill it onmouseout="killParent();".

MediaElement.js setSrc() Loading The File But Not Changing pluginType

- by doubleJ

I'm working on a page that uses mediaelement.js to play mp3/mp4/wmv (yes, we have a lot of wmv). I have a list of links and those links should change the player. My effort is to make the changes to the player through javascript so that the page doesn't refresh. This code is working, but it refreshes every time. See a live demo of the non-ajax version. <?php $file = null; $file = $_GET["file"]; $format = null; if (preg_match("/mp4/i", $file)) $format = "mp4"; if (preg_match("/webm/i", $file)) $format = "webm"; if (preg_match("/wmv/i", $file)) $format = "wmv"; if (preg_match("/mp3/i", $file)) $format = "mp3"; if (preg_match("/ogg/i", $file)) $format = "ogg"; $mime = null; if ($format == "mp4") $mime = "video/mp4"; if ($format == "webm") $mime = "video/webm"; if ($format == "wmv") $mime = "video/wmv"; if ($format == "mp3") $mime = "audio/mp3"; if ($format == "ogg") $mime = "audio/ogg"; $element = "video"; if ($format == "mp3" || $format == "ogg") $element = "audio"; // you have to escape (\) the escape (\) character (hehehe...) $poster = "media\\120701Video.jpg"; $height = "360"; if ($format == "mp3") $height = "30"; ?> <!doctype html> <html> <head> <meta charset="utf-8"> <title>Embed</title> <link rel="stylesheet" href="include/johndyer-mediaelement-b090320/build/mediaelementplayer.min.css"> <style> audio {width:640px; height:30px;} video {width:640px; height:360px;} </style> <script src="include/johndyer-mediaelement-b090320/build/jquery.js"></script> <script src="include/johndyer-mediaelement-b090320/build/mediaelement-and-player.js"></script> </head> <body> <ul> <li><a href="embed.php">Reset</a></li> <li><a href="?file=media/120701Video-AnyVideoConverter.mp4">Alternative (mp4)</a></li> <li><a href="?file=media/120701Video-Ffmpeg-Defaults.webm">Alternative (webm)</a></li> <li><a href="?file=media/AreYouHurting-Death.wmv">Alternative (wmv)</a><li> <li><a href="?file=media/AreYouHurting-Death.mp3">Alternative (mp3)</a></li> </ul> <?php if ($file) { ?> <video src="<?php echo $file; ?>" controls poster="<?php echo $poster; ?>" width="640" height="360"></video> <div id="type"></div> <script> var video = document.getElementsByTagName("video")[0]; var player = new MediaElementPlayer(video, { success: function(player) { $('#type').html(player.pluginType); } }); <?php } ?> </script> </body> </html> This code requires <video> to be loaded, initially and with a file, so that the player mode (pluginType) is set. It will, then, only play formats that the pre-established mode supports (firefox in native mode won't play mp4). See a live demo of the ajax version. <!doctype html> <html> <head> <meta charset="utf-8"> <title>Embed</title> <link rel="stylesheet" href="http://www.mediaelementjs.com/js/mejs-2.9.2/mediaelementplayer.min.css"> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> <script src="http://www.mediaelementjs.com/js/mejs-2.9.2/mediaelement-and-player.js"></script> </head> <body> <ul> <li><a href="javascript:player.pause(); player.setSrc('media/120701Video-AnyVideoConverter.mp4'); player.load(); player.play();">Alternative (mp4)</a></li> <li><a href="javascript:player.pause(); player.setSrc('media/120701Video-Ffmpeg-Defaults.webm'); player.load(); player.play();">Alternative (webm)</a></li> <li><a href="javascript:player.pause(); player.setSrc('media/AreYouHurting-Death.wmv'); player.load(); player.play();">Alternative (wmv)</a></li> <li><a href="javascript:player.pause(); player.setSrc('media/AreYouHurting-Death.mp3'); player.load(); player.play();">Alternative (mp3)</a></li> </ul> <video controls src="media/WordProductionCenter.mp4"></video> <div id="type"></div> <script> var video = document.getElementsByTagName("video")[0]; var player = new MediaElementPlayer(video, { success: function(player) { $('#type').html(player.pluginType); } }); </script> </body> </html> It seems like I need something like setType(), but I see no such option. I've read a couple pages that referenced refreshing the DOM after the javascript runs, but I haven't been able to successfully do it (I know enough about javascript to hack things around and get stuff working, but not enough to create whole new things). It is worth noting that Silverlight doesn't work with Internet Explorer 8 or Safari (not sure if it's my code, mejs, or the browsers). Also, neither Silverlight nor Flash play mp3 or webm (again, not sure where the problem lies). Is there a way to dynamically load different types of files into mediaelement?

jQueryUI Tabs: how to keep them on a single line?

- by Andi

Hi all, Maybe my question is wired: is there a way to prevent jQueryUI tabs from floating if browser window is too small? Explanation: I have a simple horizontal tab using CSS only. The content is floating but not the tabs. Important: there is no width set manually, the current width is taken automatically. Here is the code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <style type="text/css"> #tabs ul { white-space: nowrap; } #tabs ul li { display: inline; white-space: nowrap; } </style> <title>Tabs-CSS</title> </head> <body> <div class="demo"> <div id="tabs"> <ul> <li><a href="#tabs-1">Preloaded</a></li> <li><a href="ajax/content1.html">Tab 1</a></li> <li><a href="ajax/content2.html">Tab 2</a></li> <li><a href="ajax/content3-slow.php">Tab 3 (slow)</a></li> <li><a href="ajax/content4-broken.php">Tab 4 (broken)</a></li> <li><a href="ajax/content4-broken.php">Tab 4 (broken)</a></li> <li><a href="ajax/content4-broken.php">Tab 4 (broken)</a></li> <li><a href="ajax/content4-broken.php">Tab 4 (broken)</a></li> <li><a href="ajax/content4-broken.php">Tab 4 (broken)</a></li> </ul> <div id="tabs-1"> <p>Proin elit arcu, rutrum commodo, vehicula tempus, commodo a, risus.

Adding <span> tags to all text nodes between custom self closing tags.

- by Rachel

I have a pair of custom self closing tags s1 and s2 defined in namespace x in my xhtml. For each tag pair s1, s2 having the same id, I want to add span tags to all the text nodes between them. Each s1, s2 tag pair have a unique id. The s1 tag has an attribute 'styleName' which needs to be copied as the class name for the span tags populated for the s1,s2 pair. Within a s1, s2 tag pair, other s1, s2 tags can occur. It is the id attribute of the tags s1 and s2 that help us to find the postion from where we need to start populating the span(for text nodes alone) and the end where we need to stop. In case of common text nodes that is part of the multiple s1, s2 pairs then the span tags needs to be opened and closed appropirately as shown in the sample below. I am not specific with the format of the id populated for the span tag. As long as it is unique it is fine. Can we achieve this kind of a solution using XSL. I am looking for a XSL based solution for the same. I am using Saxon java processor for XSL. I am trying to achieve this using XSL 2.0. Please share your ideas on this.

Adding <span> tags to all text nodes between custom self closing tags.

- by Rachel

I have a pair of custom self closing tags s1 and s2 defined in namespace x in my xhtml. For each tag pair s1, s2 having the same id, I want to add span tags to all the text nodes between them. Each s1, s2 tag pair have a unique id. The s1 tag has an attribute 'styleName' which needs to be copied as the class name for the span tags populated for the s1,s2 pair. Within a s1, s2 tag pair, other s1, s2 tags can occur. It is the id attribute of the tags s1 and s2 that help us to find the postion from where we need to start populating the span(for text nodes alone) and the end where we need to stop. In case of common text nodes that is part of the multiple s1, s2 pairs then the span tags needs to be opened and closed appropirately as shown in the sample below. I am not specific with the format of the id populated for the span tag. Along as it is unique it is fine. Can we achive this kind of a solution using XSL. I am using Saxon processor. Sample input: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:x="http://sample.org"> <head> <title>This is my title</title> </head> <body> <h1 align="center">This <x:s1 id="1" styleName="name_1"/>is my <x:s2 id="1" />heading</h1> <p> Sample content <x:s1 id="2" styleName="name_2"/> Some text here. </p> <p> Here you <x:s2 id="2" />go. </p> <p> <x:s1 id="3" styleName="name_3"/>This <x:s1 id="4" styleName="name_4"/>is just a simple text <x:s2 id="4" />Some text here.<x:s2 id="3" /> Some content here. </p> <p> Use this <x:s1 id="5" styleName="name_5"/>space. </p> <p> Indroducing <x:s1 id="6" styleName="name_6"/> more information. </p> <p> Can add some <x:s2 id="6" />more content here. </p> <p> Sample content <x:s2 id="5" />Some text here.

Referencing CDI producer method result in h:selectOneMenu

- by user953217

I have a named session scoped bean CustomerRegistration which has a named producer method getNewCustomer which returns a Customer object. There is also CustomerListProducer class which produces all customers as list from the database. On the selectCustomer.xhtml page the user is then able to select one of the customers and submit the selection to the application which then simply prints out the last name of the selected customer. Now this only works when I reference the selected customer on the facelets page via #{customerRegistration.newCustomer}. When I simply use #{newCustomer} then the output for the last name is null whenever I submit the form. What's going on here? Is this the expected behavior as according to chapter 7.1 Restriction upon bean instantion of JSR-299 spec? It says: ... However, if the application directly instantiates a bean class, instead of letting the container perform instantiation, the resulting instance is not managed by the container and is not a contextual instance as defined by Section 6.5.2, “Contextual instance of a bean”. Furthermore, the capabilities listed in Section 2.1, “Functionality provided by the container to the bean” will not be available to that particular instance. In a deployed application, it is the container that is responsible for instantiating beans and initializing their dependencies. ... Here's the code: Customer.java: @javax.persistence.Entity @Veto public class Customer implements Serializable, Entity { private static final long serialVersionUID = 122193054725297662L; @Column(name = "first_name") private String firstName; @Column(name = "last_name") private String lastName; @Id @GeneratedValue() private Long id; public String getFirstName() { return firstName; } public void setFirstName(String firstName) { this.firstName = firstName; } public String getLastName() { return lastName; } public void setLastName(String lastName) { this.lastName = lastName; } @Override public String toString() { return firstName + ", " + lastName; } @Override public Long getId() { return this.id; } } CustomerListProducer.java: @SessionScoped public class CustomerListProducer implements Serializable { @Inject private EntityManager em; private List<Customer> customers; @Inject @Category("helloworld_as7") Logger log; // @Named provides access the return value via the EL variable name // "members" in the UI (e.g., // Facelets or JSP view) @Produces @Named public List<Customer> getCustomers() { return customers; } public void onCustomerListChanged( @Observes(notifyObserver = Reception.IF_EXISTS) final Customer customer) { // retrieveAllCustomersOrderedByName(); log.info(customer.toString()); } @PostConstruct public void retrieveAllCustomersOrderedByName() { CriteriaBuilder cb = em.getCriteriaBuilder(); CriteriaQuery<Customer> criteria = cb.createQuery(Customer.class); Root<Customer> customer = criteria.from(Customer.class); // Swap criteria statements if you would like to try out type-safe // criteria queries, a new // feature in JPA 2.0 // criteria.select(member).orderBy(cb.asc(member.get(Member_.name))); criteria.select(customer).orderBy(cb.asc(customer.get("lastName"))); customers = em.createQuery(criteria).getResultList(); } } CustomerRegistration.java: @Named @SessionScoped public class CustomerRegistration implements Serializable { @Inject @Category("helloworld_as7") private Logger log; private Customer newCustomer; @Produces @Named public Customer getNewCustomer() { return newCustomer; } public void selected() { log.info("Customer " + newCustomer.getLastName() + " ausgewählt."); } @PostConstruct public void initNewCustomer() { newCustomer = new Customer(); } public void setNewCustomer(Customer newCustomer) { this.newCustomer = newCustomer; } } not working selectCustomer.xhtml: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets"> <h:head> <title>Auswahl</title> </h:head> <h:body> <h:form> <h:selectOneMenu value="#{newCustomer}" converter="customerConverter"> <f:selectItems value="#{customers}" var="current" itemLabel="#{current.firstName}, #{current.lastName}" /> </h:selectOneMenu> <h:panelGroup id="auswahl"> <h:outputText value="#{newCustomer.lastName}" /> </h:panelGroup> <h:commandButton value="Klick" action="#{customerRegistration.selected}" /> </h:form> </h:body> </html> working selectCustomer.xhtml: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets"> <h:head> <title>Auswahl</title> </h:head> <h:body> <h:form> <h:selectOneMenu value="#{customerRegistration.newCustomer}" converter="customerConverter"> <f:selectItems value="#{customers}" var="current" itemLabel="#{current.firstName}, #{current.lastName}" /> </h:selectOneMenu> <h:panelGroup id="auswahl"> <h:outputText value="#{newCustomer.lastName}" /> </h:panelGroup> <h:commandButton value="Klick" action="#{customerRegistration.selected}" /> </h:form> </h:body> </html> CustomerConverter.java: @SessionScoped @FacesConverter("customerConverter") public class CustomerConverter implements Converter, Serializable { private static final long serialVersionUID = -6093400626095413322L; @Inject EntityManager entityManager; @Override public Object getAsObject(FacesContext context, UIComponent component, String value) { Long id = Long.valueOf(value); return entityManager.find(Customer.class, id); } @Override public String getAsString(FacesContext context, UIComponent component, Object value) { return ((Customer) value).getId().toString(); } }

Why won't my AJAX controls work? (and ajax for .net 4 not working?)

- by Nicklamort

I'm totally new to ajax. I'm using VS2005. I just downloaded .NET framework 4 and so then I downloaded ajaxcontroltoolkit.binary.net4 via [http://ajaxcontroltoolkit.codeplex.com/releases/view/43475] (as opposed to ajaxcontroltoolkit.binary.net35 for .NET 3.5), but when I try to load the ajaxcontroltoolkit.dll into my toolbox (as said in the tutorials), I get the following error msg: "'C:......\ajaxcontroltoolkit.dll' is not a microsoft .NET module." First question: Why is this happening? So I tried downloading the "Recommended" ajaxcontroltoolkit.binary.net35, and it accepted the .dll file and loaded all my controls. So, I started a new website and tried to check out a combobox, and it displays, but IE is giving the follow error msg: 'Sys.Extended.UI.PositioningMode.BottomLeft' is null or not an object.' 2nd question: Why is this happening?

Integrating PayMill: The token filled input field is not created, error "field_invalid_amount"

- by automatix

I'm implementing the Credit Card Payment form of PayMill according to the Payment Form docu. So I copied the JS from the Bridge docu page and the form from the Payment Form docu page. But no token is created. When I try to debug the JS and add console.info(error.apierror); into the paymillResponseHandler(...) function, I get the error code: field_invalid_amount. According to the support page There are three possible reasons for this error message: no amount value was provided numbers were rounded wrong delimiter symbol But the amuont is provided and I've already tried different delimiter symbols. What "numbers were rounded" means, is not clear. What can be the problem and how to fix this issue?

PHP Multiple User Login Form - Navigation to Different Pages Based on Login Credentials

- by Zulu Irminger

I am trying to create a login page that will send the user to a different index.php page based on their login credentials. For example, should a user with the "IT Technician" role log in, they will be sent to "index.php", and if a user with the "Student" role log in, they will be sent to the "student/index.php" page. I can't see what's wrong with my code, but it's not working... I'm getting the "wrong login credentials" message every time I press the login button. My code for the user login page is here: <?php session_start(); if (isset($_SESSION["manager"])) { header("location: http://www.zuluirminger.com/SchoolAdmin/index.php"); exit(); } ?> <?php if (isset($_POST["username"]) && isset($_POST["password"]) && isset($_POST["role"])) { $manager = preg_replace('#[^A-Za-z0-9]#i', '', $_POST["username"]); $password = preg_replace('#[^A-Za-z0-9]#i', '', $_POST["password"]); $role = preg_replace('#[^A-Za-z0-9]#i', '', $_POST["role"]); include "adminscripts/connect_to_mysql.php"; $sql = mysql_query("SELECT id FROM Users WHERE username='$manager' AND password='$password' AND role='$role' LIMIT 1"); $existCount = mysql_num_rows($sql); if (($existCount == 1) && ($role == 'IT Technician')) { while ($row = mysql_fetch_array($sql)) { $id = $row["id"]; } $_SESSION["id"] = $id; $_SESSION["manager"] = $manager; $_SESSION["password"] = $password; $_SESSION["role"] = $role; header("location: http://www.zuluirminger.com/SchoolAdmin/index.php"); } else { echo 'Your login details were incorrect. Please try again <a href="http://www.zuluirminger.com/SchoolAdmin/index.php">here</a>'; exit(); } } ?> <?php if (isset($_POST["username"]) && isset($_POST["password"]) && isset($_POST["role"])) { $manager = preg_replace('#[^A-Za-z0-9]#i', '', $_POST["username"]); $password = preg_replace('#[^A-Za-z0-9]#i', '', $_POST["password"]); $role = preg_replace('#[^A-Za-z0-9]#i', '', $_POST["role"]); include "adminscripts/connect_to_mysql.php"; $sql = mysql_query("SELECT id FROM Users WHERE username='$manager' AND password='$password' AND role='$role' LIMIT 1"); $existCount = mysql_num_rows($sql); if (($existCount == 1) && ($role == 'Student')) { while ($row = mysql_fetch_array($sql)) { $id = $row["id"]; } $_SESSION["id"] = $id; $_SESSION["manager"] = $manager; $_SESSION["password"] = $password; $_SESSION["role"] = $role; header("location: http://www.zuluirminger.com/SchoolAdmin/student/index.php"); } else { echo 'Your login details were incorrect.

Any help would be greatly appreciated! Many thanks, Zulu

android webview returns blank page when load dynamic html page

- by user2962555

I am trying to click one button to load a page into a div block dynamically. To test it, I try to append a list item with text "abc" into the loaded page. However, I always get a blank page. load function works fine because if I try to load a static page, it works. Following is my main html page code. <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>LoadPageTest</title> <link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Open+Sans:300,400,700"> <link rel="stylesheet" href="./css/customizedstyle.css"> <link rel="stylesheet" href="./css/themes/default/jquery.mobile-1.4.3.min.css"> <link rel="stylesheet" href="./css/jqm-demos.css"> <script src="./js/jquery.js"></script> <script scr="./js/customizedjs.js"></script> <script src="./js/jquery.mobile-1.4.3.min.js"></script> <script> $( document ).on( "pagecreate", "#demo-page", function() { $( document ).on( "swipeleft swiperight", "#demo-page", function( e ) { if ( $( ".ui-page-active" ).jqmData( "panel" ) !== "open" ) { if ( e.type === "swipeleft" ) { $( "#right-panel" ).panel( "open" ); } } }); }); </script> <style type="text/css"> body { overflow:hidden; } </style> </head> <body style= "overflow:hidden" scrolling="no"> <style type="text/css"> body { overflow:hidden; } </style> <div data-role="page" id="main-page" style= "overflow:hidden" scrolling="no"> <div role="main" class="ui-content" id ="maindiv" style= "overflow: auto"> Will load diff pages here. </div> <div data-role="panel" id="left-panel" data-theme="b"> <ul data-role="listview" data-icon="false" id="menu"> <li> <a href="#" id = "btnA" data-rel="close">Go Page A <img src="./images/icona.png" class="ui-li-thumb"/> </li> <li> <a href="#" id = "btnB" data-rel="close">Go Page B <img src="./images/iconb.png" class="ui-li-thumb"/> </li> </ul> </div> <script type="text/javascript"> $("#btnA").on("click", function(){ $("#maindiv").empty(); $("#maindiv").load("pageA.html"); }); $("#btnB").on("click", function(){ $("#maindiv").empty(); $("#maindiv").load("pageB.html"); }); </script> </div> </body> </html> Next is code for the page I try to load dynamically. <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Page should be loaded</title> <link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Open+Sans:300,400,700"> <link rel="stylesheet" href="./css/customizedstyle.css"> <link rel="stylesheet" href="./css/themes/default/jquery.mobile-1.4.3.min.css"> <link rel="stylesheet" href="./css/jqm-demos.css"> <script src="./js/jquery.js"></script> <script scr="./js/customizedjs.js"></script> <script src="./js/jquery.mobile-1.4.3.min.js"></script> <script> $(document).on('pagebeforeshow', function () { $('#postlist').append('<li> abc </li>'); $('#postlist').listview('refresh'); }); </script> </head> <body > <div data-role="page" id="posthome"> <div data-role = "content"> <ul data-role='listview' id = "postlist"> </ul> </div> </div> </body> </html> I doubt if it is because my javascript in the page doesn't work, cause the swipe js code in the main page seems not work either. Is that possible? I have enabled javascript in the onCreate() function of the activity file as below. protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_message); new LongRunningGetIO().execute(); mWebView = (WebView) findViewById(R.id.webview); mWebView.setWebViewClient(new AppClient()); mWebView.setVerticalScrollBarEnabled(false); mWebView.getSettings().setJavaScriptEnabled(true); mWebView.getSettings().setDomStorageEnabled(true); mWebView.loadUrl("file:///android_asset/index.html"); } I noticed there is a warning for statement to enable javascript "Using setJavaScriptEnabled can introduce XSS vulnerabilities into you application, review carefully". Will that maybe the reason? Then, I added @SuppressLint("SetJavaScriptEnabled") on top of the activity. The warning is gone, but the js code in pages seem still not work.

Implementing a wheeled character controller

- by Lazlo

I'm trying to implement Boxycraft's character controller in XNA (with Farseer), as Bryan Dysmas did (minus the jumping part, yet). My current implementation seems to sometimes glitch in between two parallel planes, and fails to climb 45 degree slopes. (YouTube videos in links, plane glitch is subtle). How can I fix it? From the textual description, I seem to be doing it right. Here is my implementation (it seems like a huge wall of text, but it's easy to read. I wish I could simplify and isolate the problem more, but I can't): public Body TorsoBody { get; private set; } public PolygonShape TorsoShape { get; private set; } public Body LegsBody { get; private set; } public Shape LegsShape { get; private set; } public RevoluteJoint Hips { get; private set; } public FixedAngleJoint FixedAngleJoint { get; private set; } public AngleJoint AngleJoint { get; private set; } ... this.TorsoBody = BodyFactory.CreateRectangle(this.World, 1, 1.5f, 1); this.TorsoShape = new PolygonShape(1); this.TorsoShape.SetAsBox(0.5f, 0.75f); this.TorsoBody.CreateFixture(this.TorsoShape); this.TorsoBody.IsStatic = false; this.LegsBody = BodyFactory.CreateCircle(this.World, 0.5f, 1); this.LegsShape = new CircleShape(0.5f, 1); this.LegsBody.CreateFixture(this.LegsShape); this.LegsBody.Position -= 0.75f * Vector2.UnitY; this.LegsBody.IsStatic = false; this.Hips = JointFactory.CreateRevoluteJoint(this.TorsoBody, this.LegsBody, Vector2.Zero); this.Hips.MotorEnabled = true; this.AngleJoint = new AngleJoint(this.TorsoBody, this.LegsBody); this.FixedAngleJoint = new FixedAngleJoint(this.TorsoBody); this.Hips.MaxMotorTorque = float.PositiveInfinity; this.World.AddJoint(this.Hips); this.World.AddJoint(this.AngleJoint); this.World.AddJoint(this.FixedAngleJoint); ... public void Move(float m) // -1, 0, +1 { this.Hips.MotorSpeed = 0.5f * m; }

ASP.NET 3.5/C# Menu Control in Master Page fails to use CSS styles

- by Shaun

I'm working on a web application that uses ASP.NET 3.5 and C#. Structurally, I have a master page with a menu control on it. The control serves as my navigation, and it gets its items from a SiteMapDataSource control and a corresponding Web.sitemap file. The problem is that some styles do not render properly when you specify the CssClass property. More specifically, the selected and hover styles don't respond to css styles. Consider the code below: <%@ Master Language="C#" AutoEventWireup="true" CodeFile="Site.master.cs" Inherits="Site" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.or/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title>A webpage</title> </head> <body> <form id="form1" runat="server"> <div id="page"> <asp:Menu ID="navMenu" Orientation="Horizontal" StaticMenuStyle-CssClass="staticMenu" StaticMenuItemStyle-CssClass="staticMenuItem" StaticSelectedStyle-CssClass="staticSelectedItem" StaticHoverStyle-CssClass="staticHoverItem" runat="server"> </asp:Menu> <asp:SiteMapDataSource ID="srcSiteMap" runat="server" ShowStartingNode="false" /> <br /> <asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder> </div> </form> </body> </html> Suppose I had a corresponding .css file with the following: .staticMenuItem { background-color:Red; } .staticSelectedItem { background-color:Green; } .staticHoverItem { background-color:Blue; } What will happen is that my item backgrounds will properly be red, but my selected item will not be green and the item I'm hovering my mouse over will not be blue. This seems true regardless of whether or not I include the style in the head of the master page or in an external file in default theme as specified in the web.config file. If I specify the styles in the asp.net xml like so: <asp:Menu ID="navMenu" Orientation="Horizontal" runat="server"> <StaticSelectedStyle BackColor="Green" Font-Underline="True" Font-Bold="True" /> <StaticHoverStyle BackColor="Gray" /> </asp:Menu> It appears to work properly in Firefox, but the style is never embedded in the html in Internet Explorer. Odd. Does anybody have any insight into what is causing this problem and how to neatly work around it? I'm aware I might be able to programmically determine the current page and select the corresponding menu item manually so it receives the proper style class, but before I resort to hacking C# and Javascript together to fix this functionality, I'm open to ideas. Thanks!

git local master branch stopped tracking remotes/origin/master, can't push

- by Paul Smith

Just when I thought I'd got the hang of the git checkout -b newbranch - commit/commit/commit - git checkout master - git merge newbranch - git rebase -i master - git push workflow in git, something blew up, and I can't see any reason for it. Here's the general workflow, which has worked for me in the past: # make sure I'm up to date on master: $ git checkout master $ git pull # k, no conflicts # start my new feature $ git checkout -b FEATURE9 # master @ 2f93e34 Switched to a new branch 'FEATURE9' ... work, commit, work, commit, work, commit... $ git commit -a $ git checkout master $ git merge FEATURE9 $ git rebase -i master # squash some of the FEATURE9 ugliness Ok so far; now what I expect to see -- and normally do see -- is this: $ git status # On branch master # Your branch is ahead of 'origin/master' by 1 commit. # nothing to commit (working directory clean) But instead, I only see "nothing to commit (working directory clean)", no "Your branch is ahead of 'origin/master' by 1 commit.", and git pull shows this weirdness: $ git pull From . # unexpected * branch master -> FETCH_HEAD # unexpected Already up-to-date. # expected And git branch -a -v shows this: $ git branch -a -v FEATURE9 3eaf059 started feature 9 * master 3eaf059 started feature 9 remotes/origin/HEAD -> origin/master remotes/origin/master 2f93e34 some boring previous commit # should=3eaf059 git branch clearly shows that I'm currently on * master, and git log clearly shows that master (local) is at 3eaf059, while remotes/origin/HEAD - remotes/origin/master is stuck back at the fork. Ideally I'd like to know the semantics of how I might have gotten into this, but I would settle for a way to get my working copy tracking the remote master again & get the two back in sync without losing history. Thanks! (Note: I re-cloned the repo in a new directory and manually re-applied the changes, and everything worked fine, but I don't want that to be the standard workaround.) Addendum: The title says "can't push", but there's no error message. I just get the "already up to date" response even though git branch -a -v shows that local master is ahead of /remotes/origin/master. Here's the output from git pull and git remote -v, respectively: $ git pull From . * branch master -> FETCH_HEAD Already up-to-date. $ git remote -v origin [email protected]:proj.git (fetch) origin [email protected]:proj.git (push) Addendum 2: It looks as if my local master is configured to push to the remote, but not to pull from it. After doing for remote in 'git branch -r | grep -v master '; do git checkout --track $remote ; done, here's what I have. It seems I just need to get master pulling from remotes/origin/master again, no? $ git remote show origin * remote origin Fetch URL: [email protected]:proj.git Push URL: [email protected]:proj.git HEAD branch: master Remote branches: experiment_f tracked master tracked Local branches configured for 'git pull': experiment_f merges with remote experiment_f Local refs configured for 'git push': experiment_f pushes to experiment_f (up to date) master pushes to master (local out of date)

calculater by using reverse polish notation and using a stack
