  • Java application not starting in Tomcat, Plesk 9 server

    - by netagence
    Hi I have a Plesk 9.3 CentOS 5 server on which I installed the addon to have Tomcat functions. One application I have uploaded appears in the Plesk Tomcat user panel but with a yellow exclamation mark and the error "Actual status of the application does not correspond to the status retrieved from the database". The app therefore does not run, while other uploaded test .war applications do. The server runs Tomcat tomcat5.5.23-0jpp.7.el5_2.1 which matches the requirements for the required app according the the company that made it. While searching for the solution I could find all 3 uploaded .war applications in /usr/share/tomcat5/psa-wars/domainhere.com/ but they do not seem uncompressed there even though 2 of them run fine. Not enough Tomcat / Java knowlede to go on... Any idea to help me here ? Best regards.

  • Best SSD tweaks for Windows 7

    - by Nick Berardi
    I have seen many articles about tweaking an SSD, but many of them seem outdated, or too broad (read all Windows XP, Vista, and Windows 7 general tweaks). And I know that Windows 7 has been specifically tweaked for SSD by the Windows team, so I don't want to do something that was written for Windows XP in mind and end up circumventing something the Windows team has specifically designed in to Windows 7. So my question is what are the best SSD tweaks for Windows 7 that you have found to get the performance out of your drive? I hope to make a comprehensive list in the answers below so there won't be so much disinformation in the forums about what to do and what not to do. Here are a few that I see posted up on the forums alot, and some questions to get the discussion started: Disabling Superfetch. Yes or No Disabling Page File or limiting it to a really small size such as 500 MB. Disabling Indexing. Yes or No Disabling Defragmenting. Yes or No What are your thoughts do you have any that have worked for you? When providing an answer please do your best to back it up with a reason and possibly some documentation from MSDN, TechNet, or another credible source.

  • development and music recording machine suggestions?

    - by dean nolan
    I wasn't sure if this belongs on SuperUser so flag if so. I am looking to build, primarily, a windows development machine that is also good for recording using Cubase. I know I should use seperate machines but I'm on a budget this time of year. I also havn't kept up with hardware for quite a few years. Basically I know I want quad core, multiple monitor support (no gaming requirements). A lot of RAM, very quiet case and super fast HDD (SSD OR 10,000RPM)for compiling and latency. I will store libraries and other data on a USB drive. Sound card is not needed as I will be using an audio interface, all other music recording equipment is taken care of also. I could do with some decent monitor recomendations also. All suggestions welcome, thanks.

  • How do I record sound from my CD/DVD player without other system sounds in the mix?

    - by Software Monkey
    Using GoldWave I can record via the "Stereo Mix" channel, but I get no sound on the "CD" channel. Of course, using the stereo mix also mixes in all system sounds, including beeps, etc. I have the analog out on the DVD player connected to the CD-IN connector on the MoBo. I can hear CDs and DVDs playing just fine through my speakers - is this because the CD is also IDE data connection in to deliver the sound to the sound card, then? I specifically want to record a DVD; I can easily rip a CD using GoldWave's built-in ripper. Is there anything I have forgotten or have to enable? Or is it likely I have a damaged cable? My system is an MSI mobo and is running Windows XP SP3.

  • Can it be important to call remove() on an EJB 3 stateless session bean? Perhaps on weblogic?

    - by Michael Borgwardt
    I'm in the process of migrating an EJB 2 application to EJB 3 (and what a satisfying task it is to delete all those deployment descriptors!). It used to run on Weblogic and now runs on Glassfish. The task is going very smoothly, but one thing makes me wary: The current code takes great care to ensure that EJBObject.remove() is called on the bean when it's done its job, and other developers have (unfortunately very vague) memories of "bad things" happening when that was not done. However, with EJB3, the implementation class does not implement EJBObject, so there is no remove() method to be called. And my understanding is that there isn't really any point at all in calling it on stateless session beans, since they are, well, stateless. Could these "bad things" have been weblogic-specific? If not, what else? Should I avoid the full EJB3 lightweightness and keep a remote interface that extends EJBObject? Or just write it off as cargo-cult programming and delete all those try/finally clauses? I'm leaning towards the latter, but now feeling very comfortable with it.

  • Extract points within a shape from a raster

    - by user308827
    Hi, I have a raster file (basically 2D array) with close to a million points. I am trying to extract a circle from the raster (and all the points that lie within the circle. Using ArcGIS is exceedingly slow for this. Can anyone suggest any image processing library that is both easy to learn and powerful and quick enough for something like this? Thanks!

  • PHP static objects giving a fatal error

    - by Webbo
    I have the following PHP code; <?php component_customer_init(); component_customer_go(); function component_customer_init() { $customer = Customer::getInstance(); $customer->set(1); } function component_customer_go() { $customer = Customer::getInstance(); $customer->get(); } class Customer { public $id; static $class = false; static function getInstance() { if(self::$class == false) { self::$class = new Customer; } else { return self::$class; } } public function set($id) { $this->id = $id; } public function get() { print $this->id; } } ?> I get the following error; Fatal error: Call to a member function set() on a non-object in ....../classes/customer.php on line 9 Can anyone tell me why I get this error? I know this code might look strange, but it's based on a component system that I'm writing for a CMS. The aim is to be able to replace HTML tags in the template e.g.; <!-- component:customer-login --> with; <?php component_customer_login(); ?> I also need to call pre-render methods of the "Customer" class to validate forms before output is made etc. If anyone can think of a better way, please let me know but in the first instance, I'd like to know why I get the "Fatal error" mentioned above. Cheers

  • IIS 6 Private Key certificate access

    - by gaizkile
    Hi, We have a Web asp.net application running in the framework 2.0 and hosted in an IIS 6 server, and the OS is windows server 2003. The web application is suing a client certificate to be authenticated by a web service. We have impersonalized the application pool with de user “Network Service”. The problem is when we have to access to the private key of the certificate that is stored in the machine key/my storage. The user Network Service cannot access the key. We have given privileges to the Network Service user using the winhttpcertcfg.exe tool, however the result is the same. When we impersonalize the application pool with the local administrator the result is successfully. Therefore we think that the problem is the privileges of the user. If someone could give us some information about, we would be gratefully. Thanks in advance

  • Rules engine for Silverlight?

    - by frances1983
    At the moment I'm developing a web based application using Silverlight 3.0. For the business rules I'm looking for a rules engine that's both easy to use for me and my users, which will work with SL3. Is something like that available out of the box or will I need to roll my own? I've Googled and looked around the various code sites (Codeplex, Code Project etc), but didn't see anything that suits my needs. I did also have a good long look at NxBRE, but it's Rules syntax is too complex for 'dummy' users.

  • Yahoo Pipes: filter items in a feed based on words in a text file

    - by pufferfish
    I have a pipe that filters an RSS feed and removes any item that contains "stopwords" that I've chosen. Currently I've manually created a filter for each stopword in the pipe editor, but the more logical way is to read these from a file. I've figured out how to read the stopwords out of the text file, but how do I apply the filter operator to the feed, once for every stopword? The documentation states explicitly that operators can't be applied within the loop construct, but hopefully I'm missing something here.

    - by knappy
    I cannot get scroll to work, here is the complete stuff: http://zed.mit.edu/scroll2/buc.php I'm trying to refresh the page while maintaining the scroll position of the iframe inside. I'd like to have an alert when I actively scroll the iframe, these two both fail: $(top).frames['#iframe_bucinid'].scroll(function() .... $('#iframe_bucinid').scroll(function() ... The page's iframe is defined as: <iframe class="inframe" src="bucin.php" name="bucin" id="iframe_bucinid"> Notice that getting the scrollTop works with top.frames['bucin'].document.body.scrollTop

  • FLEX, Actionscript: how can I invoke a CustomEvent ?

    - by Patrick
    hi, I've created a custom MouseEvent in Flex: package { import flash.events.MouseEvent; public class CustomMouseEvent extends MouseEvent { public var tags:Array = new Array(); public function CustomMouseEvent(type:String, tags:Array) { super(type, true); this.tags = tags; } } } Now I would like to understand how to pass the parameter tags from both Actionscript and MXML: From actionscript I'm trying something like this, but it doesn't work: newTag.addEventListener(MouseEvent.MOUSE_UP, dispatchEvent(new CustomMouseEvent(MouseEvent.MOUSE_UP,[newTag.name]))); From MXML i'm doing this and it doesn't work as well: <mx:LinkButton click="dispatchEvent(new CustomMouseEvent(MouseEvent.MOUSE_UP, bookmarksRepeater.currentItem.tags))" /> thanks

  • asynchronous .js file loading syntax

    - by taber
    Hi, I noticed that there seems to be a couple of slightly different syntaxes for loading js files asynchronously, and I was wondering if there's any difference between the two, or if they both pretty much function the same. I'm guessing they work the same, but just wanted to make sure one method isn't better than the other for some reason. :) Method One (function() { var d=document, h=d.getElementsByTagName('head')[0], s=d.createElement('script'); s.type='text/javascript'; s.src='/js/myfile.js'; h.appendChild(s); })(); /* note ending parenthesis and curly brace */ Method Two (Saw this in Facebook's code) (function() { var d=document, h=d.getElementsByTagName('head')[0], s=d.createElement('script'); s.type='text/javascript'; s.async=true; s.src='/js/myfile.js'; h.appendChild(s); }()); /* note ending parenthesis and curly brace */

  • Android - Connectivity Questions

    - by Donal Rafferty
    I have a couple of questions about connectivity on Android, if anyone has any insight it would be great. What is the default when an application wants to wirelessly connect? Is it wlan? And if wlan is switched off or there is no access points around is it 3g or gprs? Is a device always ip connected? Or when its disabled from wlan or 3g does it lose its ip address? Is an application, for example the browser only ever connected to one ip address? Or can it be connected to multiple addresses for each radio such as gprs or wifi (wlan)? Can an application decide which connection to open a socket to? For example can I create an application and decide whether to connect the socket to the wlan or gprs? Or does the OS decide? Finally how do native applications handle connectivity? In the same manner?
