  • Best practices for caching results of JSP pages?

    - by Spines
    My application has an MVC structure. How should I structure my application to allow for maximum caching? Is it sufficient to only cache the model objects that are passed to the JSP views? Or will there be a significant performance boost from caching the results of the rendering of the JSP views too?

  • navbar hover issue in ie8

    - by Joel
    I'm having a problem with a child list not hovering correctly in IE8. Other browsers and IE7 seem to work fine. Here is the site: http://rattletree.com/index_1.php If you hover over the nav bars you'll see the sub-list come into view. You can see that the arrow image is not below the navbar in IE8 only. html: <div id="navbar2"> <ul id="navbar"> <li id="index"><a href="index.php">About Rattletree</a></li> <li id="upcomingshows"><a href="upcomingshows.php">Calendar</a></li> <li id="booking"><a href="booking.php">Contact</a> <ul class="innerlist"> <li class="innerlist"><img class="arrowAdjust" src="images/curved_arrow.png"</img><a href="#">Booking Information</a></li> <li class="innerlist"><a href="#">Press</a></li> </ul> </li> <li id="instruments"><a href="instruments.php">The Band</a> <ul class="innerlist"> <li class="innerlist"><img class="arrowAdjust" src="images/curved_arrow.png"</img><a href="#">The Instruments</a></li> <li class="innerlist"><a href="#">The Players</a></li> </ul> </li> <li id="classes"><a href="classes.php">Sights &amp; Sounds</a> <ul class="innerlist"> <li class="innerlist"><img class="arrowAdjust" src="images/curved_arrow.png"</img><a href="#">Listen</a></li> <li class="innerlist"><a href="#">Photos</a></li> <li class="innerlist"><a href="#">Video</a></li> </ul> </li> <li id"classes"><a href="classes.php">Workshops &amp; Classes</a></li> </ul> </div> and css: /* OUTER LIST STYLING */ div#navbar2 { position:relative; width: 100%; border-top: solid #000 1px; border-bottom: solid #546F8B 1px; background-color: #546F8B; } div#navbar2 ul#navbar { padding: 0px; margin: 10px 0; font-family: Arial, Helvetica, sans-serif; font-size: 16px; letter-spacing:1px; color: #FFF; white-space: nowrap; display:block; } div#navbar2 ul#navbar li { position:relative; margin: 0px; padding:0px; list-style-type: none; display:inline; } div#navbar2 li a { text-decoration: none; color: #fff; margin:0; padding: 11px 12px; } div#navbar2 li a:link { color: #FFF: } div#navbar2 li a:visited { color: #ffffff; } div#navbar2 li a:hover { color: #000; background-color: #FDFFC9; } /* INNER LIST STYLING */ div#navbar2 ul#navbar li ul.innerlist{ display: none; color:#000; } div#navbar2 ul#navbar li ul.innerlist li{ color:#000; } div#navbar2 ul#navbar li:hover ul.innerlist { position: absolute; display: inline; left: 0; width: 100%; margin: 30px 0 0px 0px; padding: 0; color:#000; } div#navbar2 ul#navbar li.innerlist a { text-decoration: none; font-weight:bold; color: #000; padding: 10px 15px 20px 15px; margin:0; } div#navbar2 li.innerlist a:link { color: #000: } div#navbar2 li.innerlist a:visited { color: #000; } div#navbar2 ul#navbar li.innerlist a:hover { color: #e62d31; background-color:transparent; } img.arrowAdjust{ padding:0px 0 0 20px; margin:0; }

  • Web app that contains a check-list based task management UI?

    - by meder
    I'm looking to develop my own task application so I'm trying to study the UI of any possible in-browser apps that have some sort of functionality which has an ordered list where items can be tagged as "done" and they either get color-highlighted or move into a "DONE" column. By the way, the area would be a tinyMCE or similar editable area and not some primitive html rendering. Example:

  • Is there a good way of displaying required field indicators when using DataAnnotations in MVC 2?

    - by Jeremy Gruenwald
    I've got validation working with DataAnnotations on all my models, but I'd like to display an indicator for required fields on page load. Since I've got all my validation centralized, I'd rather not hard-code indicators in the View. Calling validation on load would show the validation summary. Has anyone found a good way of letting the model determine what's required, but checking it upon rendering the view, similar to Html.ValidationMessageFor?

  • PHP image resize using nearest-neighbor interpolation?

    - by shipshape
    I have a 16x16 sprite in PNG or GIF image format, and would like to display it on a website at 64 x 64 in all its pixelated glory. In Firefox 3.6+ and IE I can do this easily with CSS using image-rendering and -ms-interpolation-mode, but as this doesn't work in all browsers I'd like to resize the image on the fly using PHP instead. What's the best way to resize images using nearest-neighbor interpolation in PHP?

  • JSF inner datatable not respecting rendered condition of outer table.

    - by Marc
    <h:dataTable cellpadding="0" cellspacing="0" styleClass="list_table" id="OuterItems" value="#{valueList.values}" var="item" border="0"> <h:column rendered="#{item.typeA"> <h:dataTable cellpadding="0" cellspacing="0" styleClass="list_table" id="InnerItems" value="#{item.options}" var="option" border="0"> <h:column > <h:outputText value="Option: #{option.displayValue}"/> </h:column> </h:dataTable> </h:column> <h:column rendered="#{item.typeB"> <h:dataTable cellpadding="0" cellspacing="0" styleClass="list_table" id="InnerItems" value="#{item.demands}" var="demand" border="0"> <h:column > <h:outputText value="Demand: #{demand.displayValue}"/> </h:column> </h:dataTable> </h:column> </h:dataTable> public class Item{ ... public boolean isTypeA(){ return this instanceof TypeA; } public boolean isTypeB(){ return this instanceof TypeB; } ... } public class typeA extends Item(){ ... public List getOptions(){ .... } ... } public class typeB extends Item(){ ... public List getDemands(){ ... } .... } I'm having an issue with JSF. I've abstracted the problem out here, and I'm hoping someone can help me understand how what I'm doing fails. I'm looping over a list of Items. These Items are actually instances of the subclasses TypeA and TypeB. For Type A, I want to display the options, for Type B I want to display the demands. When rendering the page for the first time, this works fine. However, when I post back to the page for some action, I get an error: [3/26/10 12:52:32:781 EST] 0000008c SystemErr R javax.faces.FacesException: Error getting property 'options' from bean of type TypeB at com.sun.faces.lifecycle.ApplyRequestValuesPhase.execute(ApplyRequestValuesPhase.java:89) at com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java(Compiled Code)) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:91) at com.ibm.faces.portlet.FacesPortlet.processAction(FacesPortlet.java:193) My grasp on the JSF lifecyle is very rough. At this point, i understand there is an error in the ApplyRequestValues Phases which is very early and so the previous state is restored and nothing changes. What I don't understand is that in order to fufill the condition for rendering "item.typeA" that object has to be an instance of TypeA. But here, it looks like that object passed the condition even though it was an instance of TypeB. It is like it is evaluating the inner dataTable (InnerItems) before evaluating the outer (outerItems). My working assumption is that I just don't understand how/when the rendered attribute is actually evaluated.

  • HTML custom tags: pros & cons

    - by o_O Tync
    I'd like to use some semantic HTML tags instead of <div>s: <article>, <product>, <footer> etc. Some of them are already presented in the upcoming HTML5, however, it's not fully supported. Which are the possible cons I might face when Rendering? Using CSS, JS? The one I remember is: IE6 can't clone tags it doesn't know.

  • Fastest possible way to render 480 x 320 background as iPhone OpenGL ES textures

    - by unknownthreat
    I need to display 480 x 320 background image in OpenGL ES. The thing is I experienced a bit of a slow down in iPhone when I use 512 x 512 texture size. So I am finding an optimum case for rendering iPhone resolution size background in OpenGL ES. How should I slice the background in this case to obtain the best possible performance? My main concern is speed. Should I go for 256 x 256 or other texture sizes here?

  • embedded web browser

    - by Ilya
    Hi, I'm looking for Linux embedded web browser, or preferably just a rendering object (it will not be used for actual browsing, just for displaying web based gui). The requirements are: Written in C (small footprint) Support Dynamic HTML Support Java script Minimum dependencies on the libraries (although i understand that it can not be completely standalone) No Dependency on X11 (i.e working with direct frame qui libraries) So far i only found Embedded Konqueror. Any suggestions are welcomed, commercial solutions are OK, but open source is preferable.
