  • Need some help on tomcat URL mod_rewrite or mod_jk

    - by Redbull Fan
    I am trying to remove the context name from the url of my server. Current URL - http://www.domainname.com/MyApp/ What I need to make is to make it avaialble at - www.domainname.com/ So it is only going to host one main app and that needs to be displayed when we open www.domainname.com/ on browser. I have already tried couple of things like below - RewriteEngine On RewriteCond %{REQUEST_URI} !^/(Context/.*)$ RewriteRule ^/(.*)$ /Context/$1 [P,L] OR redirect permanent /MyApp/ abcd://domainname.com OR Using JKMount - JkMount /MyApp/* ajp13 JkMount /MyApp* ajp13 OR Deploy war file to ROOT of tomcat and make relevant chagnes in web and server.xml All of these aren't working and I keep getting a intenal error. I need a way to basically trim the tomcat URL to make short. Thanks, Andy

  • How to disable drag and drop of text within the textarea? [migrated]

    - by Manoj Agarwal
    I am working on UI Design, where I need to use Html textarea object. The sample code is: <textarea rows="5" cols="60" spellcheck="false" style="font-size:12px; font-family: Verdana;"> Abc Xyz Mnp Pqr </textarea> I don't want to disable the textarea, since there are some cross-browser issues. If I point on 'y' in 'xyz' and drag it after text 'Mnp', it will be shifted as 'Mnpyz'. I want to avoid this drag and drop feature of text within the text area.

  • Hidden Launch Bar wouldn't slide-out when moused over, now it won't hide away.

    - by Dave Keller
    When the launch bar is hidden, I have trouble getting it to slide out when I move the mouse pointer to the left side. After adjusting the settings under Settings--Appearance--Behavior, the bar no longer hides when a browser is open. Is there a fix for this. This all happened when I was looking for a way to change the icon sizes in the launch bar. Documentation from Linux.com told me to do it under Settings--Appearance, but there was no way to do it. Any help is appreciated! Thanks.

  • Why does Ubuntu's webkit inspector look just like Safari?

    - by NoBugs
    In older Ubuntu, the python-webkit inspector looked like Chrome, as you can see in these screenshots: http://stackoverflow.com/questions/13132459 (It had some annoying bugs, too.) I see Midori's inspector also looks just like Safari, and still has some bugs. In the latest 14.04's python-webkit embedded browser, the inspector actually looks just like Safari - and also seems to still have bugs (icons missing, problems selecting). Is there a reason for this drastic change, or is it just a default configuration? Is there a recommended way to get the webkit-inspector fully working?

  • Azure Florida Association: Modern Architecture for Elastic Azure Applications

    - by Herve Roggero
    Join us on November 28th at 7PM, US Eastern Time, to hear Zachary Gramana talk about elastic scale on Windows Azure. REGISTER HERE: https://www3.gotomeeting.com/register/657038102 Description: Building horizontally scalable applications can be challenging. If you face the need to rapidly scale or adjust to high load variations, then you are left with little choice. Azure provides a fantastic platform for building elastic applications. Combined with recent advances in browser capabilities, some older architectural patterns have become relevant again. We will dust off one of them, the client-server architecture, and show how we can use its modern incarnation to bypass a class of problems normally encountered with distributed ASP.NET applications.

  • Should HTTP Verbs Be Used Semantically?

    - by Xophmeister
    If I'm making a web application which integrates with a server-side backend, would it be considered best practice to use HTTP methods semantically? That is, for example, if I'm fetching data (e.g., to populate a menu, etc.), I would use GET, but to update data (e.g., save a record), I would use POST. (I realise there are other methods that may be even more appropriate, but we need to consider browser support.) I can see the benefits of this in the sense that it's effectively a RESTful API, but at a slightly increased development cost. In my previous projects, I've POST'd everything: Is it worth switching to a RESTful mindset simply for the sake of best practice?

  • error: no device connected

    - by Prabath Swarna
    I did a fresh install of 12.04 and it went fine, worked on it for several days, but one day the browser crashed and i reset the machine, after that I get this error when i boot; error: no device connected error: no device connected error: no device connected error: no device connected This comes after the BIOS confirmation, and it stays for about 30 seconds, then the grub menu comes and when I selected the default the screen becomes purple and stays like that for a whole Minuit. I thought maybe that is because I have 500GB HDD so i ran the boot-repair, It did nothing at all. I'm sure I did the boot-repair thing right, sorry I forgot the paste URL. If i reinstalled will this error persist.

  • Mouse click firing twice

    - by Luke
    I have recently switched to XUbuntu (14.04) and I have noticed that sometimes a mouse click is fired twice. E.g. I CTRL click a link and two tabs with the same content are opened in my browser. It's not behaviour I can reproduce consistently and seems to be random (to me). I also don't know of a good way to inspect the behaviour properly for debugging purposes. I have checked the double click time setting but this doesn't seem to have any impact on this. I also run XUbuntu (13.10) in a VM on my MacBook Air and this behaviour seems to absent there. At this point in time I can't really tell if this is related to the distribution or the fact that it runs in a VM. Any insights greatly appreciated.

  • How to enable Start Button in Windows 8?

    - by Gopinath
    Microsoft taken a bold move in removing Start button in Windows 8 operating system and replacing it with Metro styled Start screen. Since the early days of Microsoft Windows, all the PC users are used to Start button and missing it all of sudden in Windows 8 may disappointed many. If you are one among the users who is disappointed with missing Windows 8 button, here is a quick way to enable it back To restore Start menu in Windows 8 all you have to do is to download and install ViStart application. This freeware application magically brings back the missing Start orbit and also when you press Windows Key, it opens up the Start menu instead of switching to Windows 8 Start Screen. Note: While installation the application may ask you to install toolbars and third party application, I suggest you to uncheck them as they may change your search settings and default browser.  They may not be harmful but effects your browsing experience.

  • How can I solve display glitches and poor performance with ATI fglrx driver on my ThinkPad X100e?

    - by rewbs
    Hi all, I noticed that video performance on my Thinkpad X100e was very poor compared to Windows 7, so I installed the ATI fglrx proprietary drivers by using the "Additional Drivers" dialogue box. The system has an ATI Radeon Mobility HD 3200 chip. The result of installing the drivers is pretty devastatingly negative, with symptoms such as skewed content in windows, browser tabs and text boxes failing to refresh when their content changes. In fact, please excuse typos in this post, because I can't really see what I am typing. :) I also notice that HD video playback performance is no better - perhaps even worse - than prior to installing the drivers. Example of what I see: Here's the output of fglrxinfo: display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: ATI Radeon HD 3200 Graphics OpenGL version string: 3.3.10237 Compatibility Profile Context Output of lspci | grep -i vga: 01:05.0 VGA compatible controller: ATI Technologies Inc RS780M/RS780MN [Radeon HD 3200 Graphics] I'm on Ubuntu 10.10 with kernel 2.6.35-22-generic-pae. What can I try? Many thanks, -R

  • Is it easier to develop from scratch or not? [closed]

    - by Gnijuohz
    I am currently reading the book computer science: an overview by J. Glenn Brookshear.And In chapter 7,there is one passage as follows: In fact, it is often within this phase(modification) that a piece of software is discarded under the pretense (too often true) that it is easier to develop a new system from scratch than to modify the existing package successfully. When I read this,an article by Joel occurred to me which mentions how Mozilla shouldn't have written its browser from scratch.(The article is here) So,Is it mostly true that it's easier to develop a new system from scratch than to modify the existing one?Or it's closely related to the complexity of the system?

  • CSS hover behavior inconsistent on desktop/mobile devices [migrated]

    - by tbart
    I have a strange problem: This page looks good on desktop browsers, but the hovering effect does not seem to work correctly on at least my CM7 Android 2.3.7 device. I know hovering is not supposed to work on touch displays as it does with a mouse, but I'd like to have touch feedback, i.e. the highlight color should show once the user has tapped a menu item. This does work when the link is just a href="#" but it does not when it is a real link. I tried all sorts of stuff as you can see, to no avail. If you go back in the browser history after having tapped a real link, the item is highlighted, so the browser understands the CSS I am throwing at it. However, the javascript alert makes it clear that it only seems to interpret the link opening action and does not care about the color changing stuff. Weird that is. Workarounds welcome, preferable without javascript, but if it has to be JS, then go ahead! either go here: http://orpheus.co.at/hoverprob and Use the source, Luke! or see it here in all its glory: <html> <head> <meta name="viewport" content="width=320"> <style> #nav, #nav ul { width: 100%; float: left; list-style: none; line-height: 1; background: #fff; font-weight: bold; padding: 0; margin: 0 0 5px 0; } #nav a { display: block; color: #001834; text-decoration: none; padding: 5px 7px; } #nav li { float: left; padding: 0; width: 33%; } #nav li ul { position: absolute; left: -9999px; height: auto; margin: 0; opacity: .95; width: 100%; } #nav li a { text-align: center; height: 20px; line-height: 20px; } #nav li ul li a { text-align: left; } #nav li ul li { float: none; /* width: 316px; */ width: 100%; } #nav li:hover ul ul, #nav li:hover ul ul ul, #nav li.sfhover ul ul, #nav li.sfhover ul ul ul { left: -9999px; } #nav li:hover ul, #nav li li:hover ul, #nav li li li:hover ul, #nav li.sfhover ul, #nav li li.sfhover ul, #nav li li li.sfhover ul { left: 0; } #nav li.educate { background: #FFF0B8; /* background: #FF0000; */ /* border-radius: 5px; */ border: 5px; } #nav li.educate:hover { background: #FFCE00; /* border-radius: 5px; */ } </style> </head> <body> <div id="mobMenu"> <ul id="nav" class="nav"> <li class="educate"><a href="#">menu</a> <ul class="educate"> <li class="educate"><a href="#">href=&quot#&quot;, works</a></li> <!--(+emtpy onmouseover for iPose devices)--> <li class="educate"><a onmouseover="" href="index.html">does not work, real link</a></li> <li class="educate" id="bla"><a onmousedown="document.getElementById('bla').style.backgroundColor='Blue'; alert('Done');document.location='index.html';" href="#">JS, not interpreted in corr order</a></li> </ul> </li> </div> </body>

  • 3d js map rendering

    - by gotha
    In the past I've done a 2D tile map using HTML, CSS and Javascript. Now I have the task of creating a 3D version using the same technologies - think of it like a space map where all planets have x/y/z positions. Currently, I have no idea to do this. Is there an existing library or something I can modify to do my job? If not, what method of rendering the map should I use? It needs to be as browser independent as possible, so I can't use webgl, flash or canvas. I'm considering plain JS & HTML or SVG (using Raphael for compatibility).

    - by user93019

Why does this happens? how can i fix it? please help. Just to let you know i have my system up to date on 12.04 32 bits version, working on an Acer aspire AOD257, 1 Gb RAM, Intel® Atom™ CPU N570 @ 1.66GHz × 4 .

  • Alternative Web model

    - by Above The Gods
    One of the problems web apps have against native apps, especially on the mobile front, is the constant need to re-download each web page on request. Ultimately, this leads to slower performance. Why if web apps only download new pages if they're actually needed, not because they're simply requested. For example: perhaps the server can store a web page version in a cookie. Every slight change to the page on the server-side changes the version number. Now instead of the browser requesting a new page each time, why not just check the version number and have the server send the page if they're different? If the page similar, the user can just use a cached page. I'm sure browsers doesn't necessarily have to change to accommodate changes to this, correct?

  • Firefox installed on my ubuntu 12.04 machine but I am unable to connect to the internet(Nobody know???)

    - by Chella
    every other browser installed is working fine..! except this Firefox. what are the things that I need to check, to make firefox work on my computer. I am a newbie for ubuntu. I tried googling not got enough and clear information. Please help me. Thanks in advance..! This is the error that I am getting just before launching of the application..! Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features.

  • How difficult it is to develope Apps for Android and iOS? [on hold]

    - by netsetter
    I'm an experienced web developer in PHP, HTML, Javascript, MySQL, CSS and I'm running communities where people can register to be able to login and do some stuff. Now more and more people are requestion an App, I told them that I have no time and experience to develope Apps with many functions for such complex communities I am running, but then the users told me what would be enough for them and this sounds already simpler to me: An app to install on Android / iOS just to be able to login (+ autologin), so they appear always online in the community when they have internet connection. Then only 1 function like a counter of new activities regarding their user account (new messages, new replies, etc..), and if they click on the app then a browser window will open to read the info at the main website. So, what you think, it will be a big thing to develope such an app for the members? Is there a big diffrence between developing for Android and iOS? How to test the App if you don't have an Android or iOS phone in example?

  • Gnome-classic, new windows remain buried behind other window

    - by Naten Baptista
    This is my first question on this forum. I have recently moved from ARCH Linux to Ubuntu 11.10. I switched to using Gnome-Classic and noticed strange behaviors with the windows whenever I open them. I have setup Launchers on the Panel to launch Dolphin, Terminal and Chrome Browser. Whenever I launch any of these I notice that they open behind the current window that is in-focus instead of coming up in front. According to me any sane windows manager would by default bring up the new window in front and focus, I mean why would you want to open a window hidden behind all other window??? Is there any thing or configuration that I need to check as this problem is driving me nutts . Thanks in advance
