• JavaEE in netbeans giving BUILD FAILED error upon deployment

  - by user312402

  When I try to run my Java EE program in Netbeans consisting of servlets (java pages), JSP's, beans(java pages) and HTML pages I get this error in the output: In-place deployment at C:\Users\Derek\Documents\NetBeansProjects\EJBProject\EJBProject-war\build\web Initializing... deploy?path=C:\Users\Derek\Documents\NetBeansProjects\EJBProject\EJBProject-war\build\web&name=EJBProject-war&force=true failed on Personal GlassFish v3 Domain C:\Users\Derek\Documents\NetBeansProjects\EJBProject\EJBProject-war\nbproject\build-impl.xml:611: The module has not been deployed. BUILD FAILED (total time: 1 second) And then in the command prompt when I run asant run in the appropriate directory, I get: C:\Users\Derek\Documents\NetBeansProjects\EJBProject\nbproject\build-impl.xml:19: Class org.apache.tools.ant.taskdefs.condition.Not doesn't support the nested "antversion" element. Do you know why this would be? Why won't netbeans deploy my application so I can run and test it?

• How to compress CSS/JS in VS2010 Web Deployment Build Template?

  - by RPM1984

  Hi all, We've recently upgraded from VS2008 - VS2010 (and hence upgrading from Web Deployment Project to proper deployment project). Obviously what's new in VS2010 web deployments is the introduction of Workflow as the build process template. Previously, we used a MSBuild task in the WDP to execute the Yahoo YUI Javascript/CSS compression module to minify/compress javascript and css files. Has anyone managed to accomplish this task with Visual Studio 2010? I have seen the new "SquishIt" compressor created by Justin Etheridge, but its not ideal as it "squishes" on the fly (e.g on Application_Start - Global.ascx) - which means you still have to push out all the uncompressed files to your web server before squishing. In the Workflow designer - i can see a toolbox item called "MSBuild" - just dont know how to use it to accomplish what i want. Been searching high and wide, no-one seems to know how. Surely someone out there has done this.

• High CPU from httpd process

  - by KHWeb

  I am currently getting high CPU on a server that is just running a couple of sites with very low traffic. One of the sites is in still development going live soon. However, this site is very very slow...When browsing through its pages I can see that the CPU goes from 30% to 100% for httpd (see top output below). I have tuned httpd & MySQL, Apache Solr, Tomcat for high performance, and I am using APC. Not sure what to do from here or how to find the culprit as I have a bunch of messages on the httpd log and have been chasing dead ends for some time...any help is greatly appreciated.

• How do I share a WiX fragment in two WiX projects?

  - by Randy Eppinger

  We have a WiX fragment in a file SomeDialog.wxs that prompts the user for some information. It's referenced in another fragment in InstallerUI.wxs file that controls the dialog order. Of course, Product.wxs is our main file. Works great. Now I have a second Visual Studio 2008 Wix 3.0 Project for the .MSI of another application and it needs to ask the user for the same information. I can't seem to figure out the best way to share the file so that changing the information requested will result in both .MSIs getting the new behavior. I honestly can't tell if a merge module, an .wsi (include) or a .wixlib is the right solution. I would have hoped to find a simple example of someone doing this but I have failed thus far. Edit: Based on Rob Mensching's wixlib blog entry, a wixlib may be the answer, but I am still searching for an example of how to do this.

• Python Image Library: How to combine 4 images into a 2 x 2 grid?

  - by Casey

  I have 4 directories with images for an animation. I would like to take the set of images and generate a single image with the 4 images arranged into a 2x2 grid for each frame of the animation. My code so far is: import Image fluid64 = "Fluid64_half_size/00" fluid128 = "Fluid128_half_size/00" fluid512 = "Fluid512_half_size/00" fluid1024 = "Fluid1024_half_size/00" out_image = "Fluid_all/00" for pic in range(1, 26): blank_image = Image.open("blank.jpg") if pic < 10: image_num = "0"+str(pic) else: image_num = str(pic) image64 = Image.open(fluid64+image_num+".jpg") image128 = Image.open(fluid128+image_num+".jpg") image512 = Image.open(fluid512+image_num+".jpg") image1024 = Image.open(fluid1024+image_num+".jpg") out = out_image + image_num + ".jpg" blank_image.paste(image64, (0,0)).paste(fluid128, (400,0)).paste(fluid512, (0,300)).paste(fluid1024, (400,300)).save(out) Not sure why it's not working.

• do-while loop in Python?

  - by Eye of Hell

  I need to emulate a do-while loop in a python. But, unfortunately, following straightforward code does not work: l = [ 1, 2, 3 ] i = l.__iter__() s = None while True : if s : print s try : s = i.next() except StopIteration : break print "done" Instead of "1,2,3,done" I have the following output: [stdout:]1 [stdout:]2 [stdout:]3 None['Traceback (most recent call last): ', ' File "test_python.py", line 8, in <module> s = i.next() ', 'StopIteration '] What can I do in order to catch 'stop iteration' excepton and break a while loop properly? Example why such thing may be needed. State machine: s = "" while True : if state is STATE_CODE : if "//" in s : tokens.add( TOKEN_COMMENT, s.split( "//" )[1] ) state = STATE_COMMENT else : tokens.add( TOKEN_CODE, s ) if state is STATE_COMMENT : if "//" in s : tokens.append( TOKEN_COMMENT, s.split( "//" )[1] ) else state = STATE_CODE # re-evaluate same line continue try : s = i.next() except StopIteration : break

• Installing Recaptcha in Joomla 1.5 user registration

  - by Samuel

  I am trying to install ReCaptcha into the user registration of Joomla 1.5. This may just be an issue with Joomla but when i hit register nothing happens. I think it's doing some JavaScript form validation but there is nothing telling the user what went wrong. if, God forbid, they do fill out the form correctly Joomla will redirect the user to the homepage and give no notice of success. Is this a Joomla issue or is there something wrong with my install? Does anyone know of a plug-in or module for Joomla that would make this easier? Thanks in advance, Samuel UPDATE: Joomla does a lot of "stuff"/"something" to the $_POST and $_GET variables which was causing the reCaptcha to not function. This was for work which is past so I am not spending anymore time on it. Shameless Plug: use wordpress instead. this can be closed as I don't have time to verify which answer works

• "Randomly" occurring errors...

  - by ClarkeyBoy

  Hi, My website has a setup whereby when the application starts a module called SiteContent is "created". This runs a clearup function which basically deletes any irrelevant data from the database, in case any has been left in there from previously run functions. The module has instances of Manager classes - namely RangeManager, CollectionManager, DesignManager. There are others but I will just use these as an example. Each Manager class contains an array of items - items may be of type Range, Collection or Design, whichever one is relevant. Data for each range is then read into an instance of Range, Collection or Design. I know this is basically duplicating data - not very efficient but its my final year project at the moment so I can always change it to use Linq or something similar later, when I am not pressured by the one month deadline. I have a form which, on clicking the Save button, saves data by calling SiteContent.RangeManager.Create(vars) or SiteContent.RangeManager.Update(Range As Range, vars) (or the equivalent for other manager classes, whichever one happens to be relevant). These functions call a stored procedure to insert or update in the relevant table. Classes Range, Collection and Design all have attributes such as Name, Description, Display and several others. When the Create or Update function is called, the Manager loops through all the other items to check if an item with the same name already exists. The Update function ensures that it does not compare the item being updated to itself. A custom exception (ItemAlreadyExistsException) is thrown if another item with the same name is found. For some weird reason, if I go into a Range, Collection or Design in edit mode, change something and try to update it, it occasionally doesnt update the item. When I say occasionally I mean every 3 - 4 page loads, sometimes more. I see absolutely no pattern in when or why it occurs. I have a try-catch statement which catches ItemAlreadyExistsException, and outputs "An item with this name already exists" when caught. Occasionally it will output this; other times it will not. Does anyone have any idea why this could happen? Maybe a mistake which someone has made and solved before? I used to have regular expressions in place that the names were compared to - I believe it was [a-zA-Z]{1, 100} (between 1 and 100 lower- or upper-case characters). For some reason the customer who I am developing the site for used to get errors saying its not in the correct format. Yet he could try the same text 5 minutes later and it would work fine. I am thinking this could well be the same problem, since both problems occur at random. Many thanks in advance. Regards, Richard Clarke Edit: After much time spent narrowing down the code, I have decided to wait till my brother, who has been a programmer for at least 8 years more than I have, to come down over Easter and get him to have a look at it. If he cant solve it then I will zip the files up and put them somewhere for people to access and have a go at. I narrowed it down literally to the minimum number of files possible, and it still occurs. It seems to be about every 10th time. Having said that, I force the manager classes to refresh every 10 page loads or 5 minutes (whichever one is sooner). I may look into this - this could be causing a problem. Basically each Manager contains an array of an object. This array is populated using data from the database. The Update function takes an instance of the item and the new values to be set for the object. If it happens to be a page load where the array is reset (ie the data is loaded freshly from the database) then the object instance with the same ID wont be the same instance as the one being passed in. This explains the fact that it throws an ItemAlreadyExistsException now and then. It all makes sense now the more I think about it. If I were to pass in the ID of the object to be altered, rather than the object itself, then it should work perfectly. I will answer the question if I solve it..

• Using the Ninject NLogModule Logger in global.asax

  - by Ciaran

  I'm using Ninject for DI in my asp.net application, so my Global class inherits from NinjectHttpApplication. In my CreateKernel(), I'm creating my custom modules and DI is working fine for me. However, I notice that there is a Logger property in the NinjectHttpApplication class, so I'm trying to use this in Application_Error whenever an exception is not caught. I think I'm creating the nlog module correctly for Ninject, but my logger is always null. Here's my CreateKernel: protected override Ninject.Core.IKernel CreateKernel() { IKernel kernel = new StandardKernel(new NLogModule(), new NinjectRepositoryModule()); return kernel; } But in the following method, Logger is always null. protected void Application_Error(object sender, EventArgs e) { Exception lastException = Server.GetLastError().GetBaseException(); Logger.Error(lastException, "An exception was caught in Global.asax"); } To clarify, Logger is a property on NinjectHttpApplication of type ILogger and has the [Inject] attribute Any idea how to inject correctly into Logger?

  Hello everyone, I am developing module where-in i pick the image from photo library and put into a Sprite. I want to implement Zoom-in, Zoom-out kind of effect for a Sprite image, same like camera album images zoom in/out effect. Could someone please guide me how do i implement it? I see somewhere is that, i have to detect two touch events in TouchBegan and then Adjust the Sprite Scale size to up or down based on the distance of two fingers touch event values. Could someone please tell me, How do i detect two fingers touch values in TouchBegan? How to allow to touch and Zoom-in/out of Sprite image by user? Please give me samples. I tried already some stuff (http://groups.google.com/group/cocos2d-iphone-discuss/browse_thread/thread/61808fd6b578e5e1?hide_quotes=no&utoken=9AdrAzkAAABFNHPPibbeOSHIuKOkxTWQ066onEraO3W2r08xbUjNmAwT6_SsyC2n0d69MF_vYn77vPb7MuI5eIWgjrXT32Kd) but doesn't work for my requirement.

• Unknown runtime error number: -2146827687

  - by Simone Vellei

  I have an error in my GXT code on Internet Explorer (both Development Mode and not) when i try to attach a label to a panel. The error is "Unknown runtime error number: -2146827687" but this error in a GWT module is throws always, in other gwt modules with a label attached to the panel the error there isn't. The layout of panel is a GridFormLayout developed by me. The error is thrown when the renderComponentInCell is called (the method is called on doLayout) and the component is not rendered (else condition). private void renderComponentInCell(Component component, Element cell) { if (component.isRendered()) { cell.appendChild(component.getElement()); } else { component.render(cell); } } What can I do?

• python blocking sockets, send returns immediately

  - by Mark

  Hi, I am writing a multithreaded socket application in Python using the socket module. the server listens for connections and when it gets one it spawns a thread for that socket. the server thread sends some data to the client. but the client is not yet ready to receive it. I thought this would have caused the server to wait until the client starts recv but instead returns immediately the client then calls recv which is blocking and no data is ever received. client socket constructor self.__clientSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) self.__clientSocket.connect((server, port)) server socket constructor self.servSock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) self.servSock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) #self.servSock.settimeout(None) self.servSock.setblocking(1) self.servSock.bind((self.addr,self.port)) self.servSock.listen(5) listening accept thread try: (cs, address) = self.servSock.accept() except socket.timeout: return threadName = '\r\nClient %s:%s\r\n' % (cs, address) print threadName clientSocketHandler = ClientSocket() clientSocketHandler.setClientSocket(cs) self.clients.newThread(self.clientFunc, {clientSocketHandler : "1"}, threadName).start() server and clients send/rec methods from inside ClientSocket receivedData = self.__clientSocket.recv(1024*1024) self.__clientSocket.send(s) any ideas why send() is returning straight away?

• SWIG: Python list to uint32_t *?

  - by Lee Crabtree

  I'm trying to work with a Python module that was generated by SWIG. There's a C++ class defined that works like this (simplified): namespace Foo { class Thing { public: Thing(); ~Thing(); bool DoSomething(uint32_t x, uint32_t y, uint32_t z, uint32_t *buffer); }; }; When I try to call it from Python, I get an error about the last argument needing to be of type 'uint32_t*'. Normal Python integers work just fine for the other arguments, so I can't understand why a list of ints wouldn't work for the buffer. Any suggestions?

• Google Appengine and Python exceptions

  - by Jim

  In my Google Appengine application I have defined a custom exception InvalidUrlException(Exception) in the module 'gvu'. Somewhere in my code I do: try: results = gvu.article_parser.parse(source_url) except gvu.InvalidUrlException as e: self.redirect('/home?message='+str(e)) ... which works fine in the local GAE development server, but raises <type 'exceptions.SyntaxError'>: invalid syntax (translator.py, line 18) when I upload it. (line 18 is the line starting with 'except') The problem seems to come from the 'as e' part: if I remove it I don't get this exception anymore. However I would like to be able to access the raised exception. Have you ever encountered this issue? Is there an alternative syntax?

• pdb show different variable values than print statements

  - by martin

  Hi, everyone. I am debugging a python module with homemade c extensions. The output seems correct when I print it with 'p' in pdb. But if I use a normal print statement or pickle it, the output is wrong. What could be causing pdb to show different values than normal execution? I can even step to the print statement in debug mode, and pdb will show the correct value but the program will print the wrong one. The problem seems to happen only when I have called a certain c extension earlier. Glad to post code if that helps. Thank you.

• MVVM framework AND Prism 4?

  - by Karsten

  I just read this question. It has some nice answers, but they are over 1 year old, and a lot have changed in this space over the last year. Some of the most popular frameworks have come out in a new mayor release such as Prism and MVVM Light Toolkit. My question is somehow the same, but with one twist, I'm already using Prism 4.0 because of the region and module features. Prism 4.0 embraces MVVM, but I feel there are something which are "not lightweight", for instance interaction requests. So I'm thinking would it better to use another MVVM framework either as a substitute or a supplement for Prism 4.0?

I want to do something very very similar for a site I'm building. ShareThis offers a widget that does the same thing but it's branded and external. I'm looking for a pure Ruby solution. A gem containing a module that could be included in a Rails ApplicationHelper class would be perfect. Suggestions appreciated before I go reinventing the wheel!
