  • Tomcat 6 is really UNSTABLE when redeploying web apps

    - by EugeneP
    Do you know how to make it more stable, maybe properties to set, memory to allocate? It always hangs up when redeploying web apps, thru manager (wars), web interface or maven plugin. every second time it gives PermGenSpace, no memory errors etc. on my local machine 3gb ram. It looks like it should be manually set up to work in a stable way. How to fix such a problem?

  • Can a dropdown box using PHP / MySQL automatically select what was last saved in the database with it?

    - by wertz8090
    I am currently working on trying to get a dropdown box to display the most recently saved field each time I open a page for editing an item in an inventory. For example, let's say that my dropdown box selections are Iron, Copper, Gold, Silver, Titanium. The first time the dropdown box loads, I would like it to load in that order (the default order that I set it to). However, once a user submits a form that specifies a selection, I would like that selection to appear as the new default for the dropdown box (for example, if the user picks Gold, Gold will now display as the default). However - the new default that is selected and submitted can only appear for those fields which it is saved under (for example, since the user selected Gold, their preference is now saved as Gold and will appear as such under the field Necklace - however, Gold should not be the default for the fields Ring, Bracelet, and Earring when I open a page to view them). Basically, I need a dropdown box that can save the option of the latest selection on a page after the form is submitted, while at the same time making sure not to affect the default order of the dropdown box across other pages. Your help is much appreciated.

  • Is there a way to add detailed remote crash reporting to a Flex Air application?

    - by keyboardsamurai
    I will be releasing my Air/Flex application soon, but I am pretty sure there are a couple of bugs that may pop up on the various platforms that Air is available for. So I was wondering if there is a way to implement a mechanism, that would send an error report, logging where the error happened, to a remote server each time an app crashes? This way I might catch errors that otherwise would go unnoticed.

  • Python sort strings started with digits

    - by vlad
    I have the next list: a = ['1th Word', 'Another Word', '10th Word'] print a.sort() >>> ['10th Word', '1th Word', 'Another Word'] But I need: ['1th Word', '10th Word','Another Word'] Is there an easy way to do this? I tried: r = re.compile(r'(\d+)') def sort_by_number(s): m = r.match(s) return m.group(0) x.sort(key=sort_by_number) But some strings do not have numbers and this leads to an errors. Thanks.

  • Displaying data from linked tables in netbeans JTable

    - by Darc
    I have been writing in java for a few months now and have just started using netbeans. I have spent all day today trying to work out how to connect to an SQL database and display data from 2 tables (ie display the data from from a select statement with an inner join) in a JTable. I have tried using JPQL with the following statment SELECT j, cust.name FROM Job j JOIN j.jobnumber cust where the job table has a field called customer that references id in the customer table. This throws the exception: Caused by: Exception [TOPLINK-8029] (Oracle TopLink Essentials - 2.0.1 (Build b09d-fcs (12/06/2007))): oracle.toplink.essentials.exceptions.EJBQLException Exception Description: Error compiling the query [SELECT j, cust.name FROM Job j JOIN j.jobnumber cust], line 1, column 11: invalid navigation expression [cust.name], cannot navigate expression [cust] of type [java.lang.Integer] inside a query. at oracle.toplink.essentials.exceptions.EJBQLException.invalidNavigation(EJBQLException.java:430) What am i doing wrong? Can anyone point me to some examples of how to make a linked table java application? I am still in the very early stages of development so a complete change is not out of the question if using a mysql database isnt the best way to go about things thanks

  • Fade in an HTML element with raw javascript over 500 miliseconds.

    - by Juan C. Rois
    Hello everybody, Once again I find myself stuck by something that I just don't understand. Any help would be appreciated. I'm working on a modal window, you click something and the background is masked and a modal window shows some content. I have a div with "display:none" and "opacity:0", and when the user triggers the modal, this div will overlay everything and have certain transparency to it. In my mind, what I need to do is: Set the opacity Perform a "for" loop that will check if the opacity is less than the desired value. Inside this loop, perform a "setInterval" to gradually increment the value of the opacity until it reaches the desired value. When the desired value has been reached, perform an "if" statement to "clearInterval". My code so far is as follows: var showMask = document.getElementById('mask'); function fireModal(){ showMask.style.opacity = 0; showMask.style.display = 'block'; var getCurrentOpacity = showMask.style.opacity; var increaseOpacity = 0.02; var finalOpacity = 0.7; var intervalIncrement = 20; var timeLapse = 500; function fadeIn(){ for(var i = getCurrentOpacity; i < finalOpacity; i++){ setInterval(function(){ showMask.style.opacity = i; }, intervalIncrement) } if(getCurrentOpacity == finalOpacity){ clearInterval(); } } fadeIn(); } As you all can guess, this is not working, all it does is set the opacity to "1" without gradually fade it in. Thanks in advance for your help.

  • Calling Multiple functions simultaneously

    - by Noob
    I'm trying to call two different functions for two different HTML elements at the same time, but the second function isn't being read at all. I'm also trying to use the id to specify which corresponding elements to grab data from.

  • Looking for a Python IDE with good support for libraries (Twisted).

    - by Omega
    I'm looking for a Python IDE that can help me easily locate and manage and use the libraries on my system (Ubuntu). Specifically Twisted. Code completion is important including the symbols I import. (I've so far had a look at PyDev as well as OpenKomodo, but while both offer code completion for default Python concepts, I wasn't able to get either to import Twisted into my project and was thus getting reference errors.) Usual disclaimer: I don't like EMACS or vi, please, nothing regarding those.

  • How can I make this jQuery plugin chainable after all image load events have completed?

    - by BumbleB2na
    [UPDATE] Solution I decided on: Decided that passing in a callback to the plugin will take care of firing an event once all images have completed loading. Chaining is also still possible. Updated Fiddle I am building a chainable jQuery plugin that can load images dynamically. (View the following code as a JSFiddle) Html: <img data-img-src="http://www.lubasf.com/blog/wp-content/uploads/2009/03/gnome.jpg" style="display: none" /> <img data-img-src="http://buffered.io/uploads/2008/10/gnome.jpg" style="display: none" /> Instead of adding in a src attribute, I give these images a data-img-src attribute. My plugin uses the value of that to fill the src. Also, these images are hidden to begin with. jQuery plugin: (function(jQuery) { jQuery.fn.loadImages = function() { var numToLoad = jQuery(this).length; var numLoaded = 0; jQuery(this).each(function() { if(jQuery(this).attr('src') == undefined) { return jQuery(this).load(function() { numLoaded++; if(numToLoad == numLoaded) return this; // attempt at making this plugin // chainable, after all .load() // events have completed. }).attr('src', jQuery(this).attr('data-img-src')); } else { numLoaded++; if(numToLoad == numLoaded) return this; // attempt at making this plugin // chainable, after all .load() // events have completed. } }); // this works if uncommented, but returns before all .load() events have completed //return this; }; })(jQuery); // I want to chain a .fadeIn() after all images have completed loading $('img[data-img-src]').loadImages().fadeIn(); Is there a way to make this plugin chainable, and have my fadeIn() happen after all images have loaded?

  • Can a Java HashMap's size() be out of sync with its actual entries' size ?

    - by trix
    I have a Java HashMap called statusCountMap. Calling size() results in 30. But if I count the entries manually, it's 31 This is in one of my TestNG unit tests. These results below are from Eclipse's Display window (type code - highlight - hit Display Result of Evaluating Selected Text). statusCountMap.size() (int) 30 statusCountMap.keySet().size() (int) 30 statusCountMap.values().size() (int) 30 statusCountMap (java.util.HashMap) {40534-INACTIVE=2, 40526-INACTIVE=1, 40528-INACTIVE=1, 40492-INACTIVE=3, 40492-TOTAL=4, 40513-TOTAL=6, 40532-DRAFT=4, 40524-TOTAL=7, 40526-DRAFT=2, 40528-ACTIVE=1, 40524-DRAFT=2, 40515-ACTIVE=1, 40513-DRAFT=4, 40534-DRAFT=1, 40514-TOTAL=3, 40529-DRAFT=4, 40515-TOTAL=3, 40492-ACTIVE=1, 40528-TOTAL=4, 40514-DRAFT=2, 40526-TOTAL=3, 40524-INACTIVE=2, 40515-DRAFT=2, 40514-ACTIVE=1, 40534-TOTAL=3, 40513-ACTIVE=2, 40528-DRAFT=2, 40532-TOTAL=4, 40524-ACTIVE=3, 40529-ACTIVE=1, 40529-TOTAL=5} statusCountMap.entrySet().size() (int) 30 What gives ? Anyone has experienced this ? I'm pretty sure statusCountMap is not being modified at this point. There are 2 methods (lets call them methodA and methodB) that modify statusCountMap concurrently, by repeatedly calling incrementCountInMap. private void incrementCountInMap(Map map, Long id, String qualifier) { String key = id + "-" + qualifier; if (map.get(key) == null) { map.put(key, 0); } synchronized (map) { map.put(key, map.get(key).intValue() + 1); } } methodD is where I'm getting the issue. methodD has a TestNG @dependsOnMethods = { "methodA", "methodB" } so when methodD is executing, statusCountMap is pretty much static already. I'm mentioning this because it might be a bug in TestNG. I'm using Sun JDK 1.6.0_24. TestNG is testng-5.9-jdk15.jar Hmmm ... after rereading my post, could it be because of concurrent execution of outside-of-synchronized-block map.get(key) == null & map.put(key,0) that's causing this issue ?

  • What's the best CDN for image hosting on a high-volume web site?

    - by Mike
    Akamai is way too expensive. Photobucket is not reliable. Is there a great content delivery network that I can use just to host my images? We deploy images programmatically via FTP, so there is some programming behind the scenes. Having some sort of reporting about the reliability of the service, whether it's raw logs files or a web-based admin screen that shows http errors, would also be important. Has anyone worked with edgecast?

  • How to set up WebLogic 10.3.3. security for JAX_WS web services?

I set the web.xml (see code fragment below) but I have tough time configuring WebLogic. I added IdentityAssertionAuthenticator Authentication Provider, set it as Required, modified DefaultAuthenticator as Optional and I went to deployed application's security and set the role to "thisIsUser" and at some point it worked, but not anymore (I redeployed war file and set web service security the same way but no avail.)
