  • Unable to use JConsole with Tomcat running as windows service

    - by Kees de Kooter
    I am running tomcat 6.0.18 as a windows service. In the service applet the jvm is configured default, i.e. it is using jvm.dll of the JRE. I am trying to monitor this application with JConsole but cannot connect to it locally. I added the parameter -Dcom.sun.management.jmxremote (which works when starting tomcat with the start.bat script). But the jvm does not seem to pick up the parameter.

  • Python + QT + Gstreamer

    - by Ptterb
    Hi everyone, I'm working with PyQt and trying to get video from a webcam to play within a QT widget. I've found tutorials for C and Qt, and for python and gtk, but NOTHING for this combo of pyQt and gstreamer. Anybody get this working? This plays the video fine, but in a separate window: self.gcam = gst.parse_launch('v4l2src device=/dev/video0 ! autovideosink') self.gcam.set_state(gst.STATE_PLAYING) what I need is to get the overlay working so it's displayed within a widget on my GUI. Thanks, Gurus of the internet! ok, so I've gotten a lot farther, but still in need of some help. I'm actually writing this for Maemo, but the following code works fine on my linux laptop: class Vid: def __init__(self, windowId): self.player = gst.Pipeline("player") self.source = gst.element_factory_make("v4l2src", "vsource") self.sink = gst.element_factory_make("autovideosink", "outsink") self.source.set_property("device", "/dev/video0") self.scaler = gst.element_factory_make("videoscale", "vscale") self.window_id = None self.windowId = windowId self.player.add(self.source, self.scaler, self.sink) gst.element_link_many(self.source,self.scaler, self.sink) bus = self.player.get_bus() bus.add_signal_watch() bus.enable_sync_message_emission() bus.connect("message", self.on_message) bus.connect("sync-message::element", self.on_sync_message) def on_message(self, bus, message): t = message.type if t == gst.MESSAGE_EOS: self.player.set_state(gst.STATE_NULL) elif t == gst.MESSAGE_ERROR: err, debug = message.parse_error() print "Error: %s" % err, debug self.player.set_state(gst.STATE_NULL) def on_sync_message(self, bus, message): if message.structure is None: return message_name = message.structure.get_name() if message_name == "prepare-xwindow-id": win_id = self.windowId assert win_id imagesink = message.src imagesink.set_property("force-aspect-ratio", True) imagesink.set_xwindow_id(win_id) def startPrev(self): self.player.set_state(gst.STATE_PLAYING) print "should be playing" vidStream = Vid(wId) vidStream.startPrev() where wId is the window id of the widget im trying to get to display the output in. When I run this on the N900, the screen goes black and blinks. Any ideas? I'm dying here!

  • IE7 issue - cannot download streamed file when Automatic prompting for file downloads is disabled

    - by Jai ganesh K
    Hi, My application is J2EE (JSP/Servlet) based. I encounter an issue when i try to open a new window (pop-up) from JSP and call a Servlet action (e.g. Streamer.do) which streams a PDF file inside that pop-up. Problem: While IE 7 - Tools - Internet Options - Security - Custom Level - Downloads - Automatic prompting for file downloads is Disabled and while pop-up window get opened, I am unable to download the file (Save/Open prompt is not comming up). In contrast, when I enable this option, I am able to download. But this option sometimes would be disabled in some environments. While testing this in Mozilla Firefox 3.0/3/5/IE6 it is working fine without any settings change. When i check it to enable i then get the Save/Open prompt to work correctly. This should be problem with IE7. Can anybody help us with Javascript or any working settings which doesnt care whether the "Automatic prompting for downloads" option in IE7 is enabled. Any help in this would be much appreciated. Regards! Jai

  • jQuery Flow Control (if then from URL params)

    - by Ryan Max
    Strangely enough I am more familiar with jQuery than I am with javascript. I need to be able to add a class to the body tag of a document depending on what specific forum page i'm on in a phpbb forum. Due to the nature of phpbb I can't actually do this flow control in php, so I am using jquery. Here's my code (the first part is an extend that gets the url parameters like so http://www.mysite.com/viewforum.php?f=3 var forum = $.getUrlVar('f'); will make forum == 3 because of the nature of phpbb i can't really do any flow control with php. So I am using jquery. This is my code: $(document).ready(function(){ $.extend({ getUrlVars: function(){ var vars = [], hash; var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&'); for(var i = 0; i < hashes.length; i++) { hash = hashes[i].split('='); vars.push(hash[0]); vars[hash[0]] = hash[1]; } return vars; }, getUrlVar: function(name){ return $.getUrlVars()[name]; } }); }); $(document).ready(function(){ var forum = $.getUrlVar('f'); if (forum == 3){ $('body').toggleClass('black'); } }); Yet this isn't working. Any idea why not?

  • Animate UserControl in WPF?

    - by sanjeev40084
    I have two xaml file one is MainWindow.xaml and other is userControl EditTaskView.xaml. In MainWindow.xaml it consists of listbox and when double clicked any item of listbox, it displays other window (edit window) from EditView userControl. I am trying to animate this userControl everytime whenever any item from the listbox is double clicked. I added some animation in userControl however the animation only gets run once. How can i make my animation run everytime whenever any item from the listbox is clicked? <ListBox x:Name="lstBxTask" Style="{StaticResource ListBoxItems}" MouseDoubleClick="lstBxTask_MouseDoubleClick"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <Rectangle Style="{StaticResource LineBetweenListBox}"/> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Taskname}" Style="{StaticResource TextInListBox}"/> <Button Name="btnDelete" Style="{StaticResource DeleteButton}" Click="btnDelete_Click"/> </StackPanel> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> <ToDoTask:EditTaskView x:Name="EditTask" Grid.Row="1" Grid.RowSpan="2" Grid.ColumnSpan="2" Visibility="Collapsed"/> In the MainWindow code, there is mouse double click event, which changes the visibility of EditTaskView to Visible. Suggestions?

  • How does heap compaction work quickly?

    - by Mason Wheeler
    They say that compacting garbage collectors are faster than traditional memory management because they only have to collect live objects, and by rearranging them in memory so everything's in one contiguous block, you end up with no heap fragmentation. But how can that be done quickly? It seems to me that that's equivalent to the bin-packing problem, which is NP-hard and can't be completed in a reasonable amount of time on a large dataset within the current limits of our knowledge about computation. What am I missing?

  • Multiple undo managers for a text view

    - by Rui Pacheco
    Hi, I've a text view that gets its content from an attributed string stored in a model object. I list several of these model objects in a drawer and when the user clicks on one the text view swaps its content. I now need to also swap the undo manager for the text view. I initialise an undo manager on my model object and use undoManagerForTextView to return it to the text view, but something's not quite right. Strategically placed logging statements show me that everything's working as planned: on startup a new model object is initialised correctly and a non-null undo manager is always pulled by the text view. But when it comes to actually doing undo, I just can't get the behaviour I want. I open a window, type something and press cmd+z, and undo works. I open a window, type something, select a new model on the table, type something, go back to the first model and try to undo and all I get is a beep. Something on the documentation made me raise an eyebrow, as it would mean that I can't have undo with several model objects: The default undo and redo behavior applies to text fields and text in cells as long as the field or cell is the first responder (that is, the focus of keyboard actions). Once the insertion point leaves the field or cell, prior operations cannot be undone.

  • R: dev.copy2pdf, multiple graphic devices to a single file, how to append to file?

    - by Timtico
    Hi everybody, I have a script that makes barplots, and opens a new window when 6 barplots have been written to the screen and keeps opening new graphic devices whenever necessary. Depending on the input, this leaves me with a potential large number of openened windows (graphic devices) which I would like to write to a single PDF file. Considering my Perl background, I decided to iterate over the different graphics devices, printing them out one by one. I would like to keep appending to a single PDF file, but I do not know how to do this, or if this is even possible. I would like to avoid looping in R. :) The code I use: for (i in 1:length(dev.list()) { dev.set(which = dev.list()[i] dev.copy2pdf(device = quartz, file = "/Users/Tim/Desktop/R/Filename.pdf") } However, this is not working as it will overwrite the file each time. Now is there an append function in R, like there is in Perl. Which allows me to keep adding pages to the existing pdf file? Or is there a way to contain the information in a graphic window to a object, and keep adding new graphic devices to this object and finally print the whole thing to a file? Other possible solutions I thought about: writing different pdf files, combining them after creation (perhaps even possible in R, with the right libraries installed?) copying the information in all different windows to one big graphic device and then print this to a pdf file.

  • IE9 selectAllChildren on an out-of-view element

    - by MrSlayer
    I am trying to replicate a service that is provided by Tynt.com that appends some text to a user's selection when copying. I understand that users don't particularly like this, but it is a client's request to append the URL and copyright notice whenever a user copies something from their website. In current browsers, I am able to do this by creating a DOM element, adding the selected text, appending the copyright text and then selecting the new node: var newSelection = document.createElement( 'div' ); newSelection.style.cssText = "height: 1px; width: 1px; overflow: hidden;"; if( window.getSelection ) { var selection = window.getSelection( ); if( selection.getRangeAt ) { var range = selection.getRangeAt( 0 ); newSelection.appendChild( range.cloneContents( ) ); appendCopyright( ); document.body.appendChild( newSelection ); selection.selectAllChildren( newSelection ); // ... remove element, return selection } } In IE9, this errors out on the selection.selectAllChildren( newSelection ) statement and I was able to figure out that this is because newSelection was effectively "hidden" from the viewport due to the styles applied in the second line above. Commenting that out works, but obviously the new node is shown to the end user. It appears that this was resolved in later versions of IE, but I am having trouble coming up with a workaround that is sufficient for IE9, a browser that I need to support. I've tried a variety of alternatives, like setting visibility: hidden;, positioning it off-screen, and trying some alternative selection functions, but they each present different problems. The error thrown by IE is: SCRIPT16389: Unspecified error.

  • How to use visibilitychange event on Firefox Extensions

    - by Tom S.
    I'm trying to learn how to make a firefox extension. I want to create a toolbar that only shows up on a specific page. I can make the toolbar appear, but then it should become hidden when I open or switch to a new tab, or close the tab with that specific page. I don't understand how to make the visibilitychange event work though, no matter what I try nothing happens. window.addEventListener("load", function load(event){ window.removeEventListener("load", load, false); myExtension.init(); },false); var myExtension = { init: function (aEvent) { gBrowser.addEventListener("DOMContentLoaded", this.showToolbar, false); }, showToolbar: function(aEvent) { var doc = aEvent.originalTarget; if(doc.location.href=="http://www.google.ca/"){ eToolbar=document.getElementById("nav-toolbar"); eToolbar.hidden=false; //no matter how I change this line below it never does anything gBrowser.addEventListener("mozvisibilitychange", this.toggleToolbar, false); } }, toggleToolbar: function(aEvent) { eToolbar=document.getElementById("nav-toolbar"); if(document["mozVisibilityState"]=="mozHidden"){ eToolbar.hidden=true; } else { eToolbar.hidden=false; } } }

  • Can we use JCR API over MySQL?

    - by n_mysql
    Apache Jackrabbit (or the JCR API) helps you separate the data store from the data management system. This would mean that every data store provider would have to implement the JCR API for his own data store. The question is JCR implemented for MySQL? Can we use the JCR API over MySQL? I want to truly abstract out where i store my content, so that tomorrow if i don't want to use a relational DB i can swap it out with the file system with ease.
