• Location of Java dump heap file?

  - by Jim Ferrans

  Well this is embarrassing ... I'm starting to play with the Eclipse Memory Analyzer to look for Java memory leaks on a Windows box. Step 1 is to obtain a heap dump file. To do this< I start my Java (javaw.exe) process from within Eclipse and connect to it with jconsole. Then on the jconsole MBeans tab I click the dumpHeap button. The first time I did this, I saw a pop-up saying it had created the heap dump file, but not giving its name or location. Now whenever I do a dumpHeap again while connected to a different javaw.exe process, jconsole says: Problem invoking dumpHeap : java.io.IOException: File exists and of course doesn't give its name or path. Where could it be? I've searched my C: drive (using cygwin command line tools) for files containing "hprof" or "java_pid" or "heapdump" and didn't find anything plausible. I've even used the Windows search to look for all files in my Eclipse workspace that have changed in the last day. I'm using the Sun Java 1.6 JVM, and don't have -XX:HeapDumpPath set.

• FileSystemWatcher.Changed fires immediately when Excel 2007 opens XLS file in compatibility mode

  - by Rick Mogstad

  We use a FileSystemWatcher to monitor documents opened from our Document Management system, and if the user saves the document, we ask if they would also like them updated in our system. We have a problem with XLS files in Excel 2007 (have not verified that the problem does not exist in 2003, but it only seems to be files that open in compatibility mode in 2007) where the Changed event fires immediately upon opening the file, and then once more upon closing the file, even if nothing has changed or the user chooses not to save upon closing. This same behavior does not exist when opening XLSX files. I wrote a test app to verify the behavior, which you can find at (http://www.just2guys.net/SOFiles/FSWExcel.zip). In the app, there is one FileSystemWatcher for each NotifyFilter type, so that it is apparent why the Changed event was fired. Any way you can think of to only prompt the user when the document is actually saved in some way by the user? I can start monitoring the file after Process.Start is called, which allows me to skip the message upon opening the document, but I still get one upon closing the document, even when nothing was changed.

• Calculating File size before download - Downloading NSURLConnection Slider timing

  - by sagar

  Ok ! Coming to the point directly. What I want to do is explained as follows. I have an url of MP3 file. ( for example Sound File ) Now, When user starts application. Download should start & for that I have implemented following methods. -(void)viewDidLoad { [super viewDidLoad]; NSURL *url=[NSURL URLWithString:@"http://xyz.pqr.com/abc.mp3"]; NSURLRequest *req=[NSURLRequest requestWithURL:url cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:120]; NSURLConnection *con=[[NSURLConnection alloc] initWithRequest:req delegate:self startImmediately:YES]; if(con){ myWebData=[[NSMutableData data] retain]; } else { // [MainHandler performSelector:@selector(targetSelector:) withObject:nil]; } } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { NSLog(@"%@",@"connection established"); [myWebData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSLog(@"%@",@"connection receiving data"); [myWebData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"%@",@"connection failed"); [connection release]; // [AlertViewHandler showAlertWithErrorMessage:@"Sorry, there is no network connection. Please check your network and try again."]; // [self parserDidEndDocument:nil]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; } Now, Above methods work perfectly for downloading. But missing points are as follows. I can not get the exact size which is going to be downloaded. ( means I want to know what is the size of file - which is going to be download )

  - by Daniil Harik

  Hello, At moment I want to implement picture upload without using any plug-ins. My upload form looks like this <form action="/Member/UploadPicture" enctype="multipart/form-data" id="uploadform" method="post"> <span style="display: none;"> <div class="upload" id="imgUpl"> <h3>Upload profile picture</h3> <div class="clear5"></div> <input type="file" name="file" id="file" /> <button class="btn-bl" id="upComplete"><span>Upload</span></button> </div> </span> </form> And my jQuery code is: $('#upComplete').click(function () { $('#up').hide(); $('#upRes').show(); var form = $("#uploadform"); $.ajax({ type: "POST", url: "/Member/UploadPicture", data: form.serialize(), success: function (data) { alert(data); } }); $.fancybox.close(); return false; }); If I open firebug, I can see that ajax() method does simple form post (not multi-part) and POST content is empty Is it possible to do files upload using jQuery ajax() method or should I do this in any other way? Thank You very much

• iCal file that will update the attendee list?

  - by Peyton Manning

  So I want to add an iCal file to a web page, so that people can add an event to their calendars. But when I view the event in my calendar (Outlook 2007) I want to see everyone who will be attending. How can I do that? I just started experimenting with this, I used Outlook's Save As to create an iCal file for a single event. That works, I can link to that file and other people can add the event to their calendars. But it doesn't tell me who has added it. Here is the (Outlook-generated) code: BEGIN:VCALENDAR PRODID:-//Microsoft Corporation//Outlook 12.0 MIMEDIR//EN VERSION:2.0 METHOD:PUBLISH X-MS-OLK-FORCEINSPECTOROPEN:TRUE BEGIN:VEVENT CLASS:PUBLIC CREATED:20100413T175736Z DESCRIPTION:I want to see if the attendee list is updated when someone adds this event.\n DTEND:20100421T153000Z DTSTAMP:20100413T175736Z DTSTART:20100421T150000Z LAST-MODIFIED:20100413T175736Z LOCATION:Wherever PRIORITY:5 SEQUENCE:0 SUMMARY;LANGUAGE=en-us:Totally fake event TRANSP:OPAQUE UID:040000008200E00074C5B7101A82E00800000000604A0119F8DACA01000000000000000 0100000004D19467F69BF6041A0B0FAFFECA1864B X-ALT-DESC;FMTTYPE=text/html:\n\n\n\n\n\n\n\n\nI want to see if the attendee list is updated when someone adds this e vent.\n\n\n X-MICROSOFT-CDO-BUSYSTATUS:BUSY X-MICROSOFT-CDO-IMPORTANCE:1 X-MICROSOFT-DISALLOW-COUNTER:FALSE X-MS-OLK-ALLOWEXTERNCHECK:TRUE X-MS-OLK-AUTOFILLLOCATION:FALSE X-MS-OLK-CONFTYPE:0 BEGIN:VALARM TRIGGER:-PT15M ACTION:DISPLAY DESCRIPTION:Reminder END:VALARM END:VEVENT END:VCALENDAR

• How to provide a fileDownloadName only if the user requests to save the file in ASP.NET MVC?

  - by davekaro

  I've got a controller action that returns a FileResult like this return this.File("file.pdf", "application/pdf"); for the URL "/Download/322" - where 322 is the id of the file. This works great, so that if a user clicks on a link to the PDF - it will open in their web browser as long as they have a PDF plugin installed. But, what if they right-click the link and choose "Save as..."? The browser pops up with the filename as "322." I'd like to have a better filename at this point, by doing something like this: return this.File("file.pdf", "application/pdf", "file.pdf"); But if I change the controller to return like that, then it will always pop up the download box, since MVC is setting the Content-Disposition header to attachment (so I can't embed the file). In summary, can I somehow detect that the user is trying to download the file vs. the file is just being embedded in something on the page?

• Loading xap file on demand

  - by synergetic

  I have Silverlight application called MyApp. During startup MyApp loads MyApp.Main.xap module using the following code: WebClient wc = new WebClient(); wc.OpenReadCompleted += new OpenReadCompletedEventHandler(onMainModuleLoaded); Uri uri = new Uri("MyApp.Main.xap", UriKind.Relative); wc.OpenReadAsync(uri); It works. Within MyApp.Main I would like to load another xap file MyApp.Billing.xap, so I wrote like the same as above WebClient wc = new WebClient(); wc.OpenReadCompleted += new OpenReadCompletedEventHandler(onBillingModuleLoaded); Uri uri = new Uri("MyApp.Billing.xap", UriKind.Relative); wc.OpenReadAsync(uri); but it throws an error saying the file not found. MyApp.Billing.xap file is inside ClientBin folder and I can download it directly via absolute path in a browser. If I try to download MyApp.Billing.xap not from inside MyApp.Main, but from inside MyApp (instead of MyAPp.Main.xap) it also works fine. What might be the problem?

  Hi everyone... i am trying to create a internet radio....

Now when i run the webpage to connect to the radio with the flash player, i get the error in firebug as "xx.xx.xxx.xxx:8000/crossdomain.xml 404 NOT FOUND" But i have created a crossdomain.xml file in the root of the xx.xx.xxx.xxx server... Still it doesn't recognize the file... Can anyone tell me where exactly i should create the file for my setting...??? Thanks a lot in advance.....

• Updating CoreData xcdatamodel file troubles - attribute type change

  - by San

  I noticed several questions related to this topic go unanswered. Is this such a gray area that nobody really understands it? Here is my problem: I am a midway in the development of my app and the app has never been used ouside of my iphone simulator.One of the attributes in my core data structure requires a type change.Since my app has never been used outside of my iPhone Simulator, I first deleted the sqlite file. Doubling the effort of this step, I also went into iPhone Simulator menu and selected "Reset Content and Settings...". Than, I edited the xcdatamodel file and changed the type of my attribute. I saved the file and exited. Without any other changes, I compiled. I expected it to fail because of my type change. It did not! After this, I assigned a value with new type to my attribute and it fails to compile?! Is there something else that I need to do for the change to take an effect? I would really, really appreciate an answer to my question. Thank you!

• Declaring struct in header file

  - by wrongusername

  I've been trying to include a structure called "student" in a student.h file, but I'm not quite sure how to do it. My student.h file code consists of entirely: #include<string> using namespace std; struct Student; while the student.cpp file consists of entirely: #include<string> using namespace std; struct Student { string lastName, firstName; //long list of other strings... just strings though }; Unfortunately, files that use #include "student.h" come up with numerous errors like error C2027: use of undefined type 'Student', error C2079: 'newStudent' uses undefined struct 'Student' (where newStudent is a function with a Student parameter), and error C2228: left of '.lastName' must have class/struct/union. It appears the compiler (VC++) does not recognize struct Student from "student.h" or something? I have tried declaring the whole struct in "student.h", but it didn't help either. How can I declare struct Student in "student.h" so that I can just #include "student.h" and start using the struct? BTW, it seems there are no compiler errors in student.h...

• Executable war file that starts jetty without maven

  - by twilbrand

  I'm trying to make an "executable" war file (java -jar myWarFile.war) that will start up a jetty webserver that hosts the webapp contained in the war file I executed. I found a page that described how to make what I'm looking for: http://eclipsesource.com/blogs/2009/10/02/executable-wars-with-jetty/ however, following that advice along with how I think I'm supposed to make an executable jar (war) isn't working. I have an ant task creating a war with a manifest that looks like: Manifest-Version: 1.0 Ant-Version: Apache Ant 1.7.1 Created-By: 1.5.0_18-b02 (Sun Microsystems Inc.) Main-Class: Start The contents of the war look like: > Start.class > jsp > build.jsp > META-INF > MANIFEST.MF > WEB-INF > lib > jetty-6.1.22.jar > jetty-util.6.1.22.jar When I try to execute the .war file, the error is: Exception in thread "main" java.lang.NoClassDefFoundError: org/mortbay/jetty/Handler Caused by: java.lang.ClassNotFoundException: org.mortbay.jetty.Handler at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) Could not find the main class: Start. Program will exit. There appears to be two errors here, one where it seems the jar files can't be found and one where the Start.class can't be found. To fix the first one, I put the jetty .jar files in the base of the war and tried again, same error. I also tried adding the WEB-INF/lib/ to the Class-path attribute of the manifest. That did not work either. Does anyone have any insight as to what I'm doing right/wrong and how I can get this executable war up and running?

• How to get a file path from c drive in android

  - by Thomas Mathew

  I was trying to extract the content of a pdf file and display its content in android. I tired the code in java and it worked.But when i am coding it in android, its not displaying anything. I think, its not getting the file path. Is there any way by which i could get a file stored in c drive and store its path in a string? The code is given below: public class hello extends Activity { /** Called when the activity is first created. */ private static String INPUTFILE = "FirstPdf.pdf"; String str; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); try { Document document = new Document(); document.open(); PdfReader reader = new PdfReader(INPUTFILE); int n = reader.getNumberOfPages(); str=PdfTextExtractor.getTextFromPage(reader, 2); } catch (IOException e) { //e.printStackTrace(); } catch (InterruptedException e) { e.printStackTrace(); } TextView tv = new TextView(this); tv.setText(str); setContentView(tv); } } I would be very grateful if the problem is solved.

• Problem connecting to Apache Derby using Hibernate configuration file in Netbeans (ERROR XSDB6)

  - by me_here

  I've created a local Apache Derby database in Netbeans, but am having problems when I try and autogenerate the POJO files, using the "Hibernate Reverse Engineering Wizard". My Hibernate configuration (generated by Netbeans from the database connection, then I added a few bits): <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- Default Netbeans generated parameters --> <property name="hibernate.connection.driver_class">org.apache.derby.jdbc.EmbeddedDriver</property> <property name="hibernate.connection.url">jdbc:derby:C:/CerealDatabase</property> <property name="hibernate.connection.username">cerealuser</property> <property name="hibernate.connection.password">cerealpass</property> <!-- Additional parameters --> <property name="hibernate.dialect">org.hibernate.dialect.DerbyDialect</property> <property name="hibernate.show_sql">true</property> <property name="hibernate.default_schema">CEREALUSER</property> </session-factory> </hibernate-configuration> When I try and generate the POJOs using this configuration file, I get the message to check my configuration file, and the derby.log gives the errors: java.sql.SQLException: Failed to start database 'C:/CerealDatabase', see the next exception for details.

I've closed any other connections to the database before trying this, and there is no "db.lck" lock file at the time, which indicates there are no connections to the database as I understand it. Does anyone have any ideas? Help gratefully received.

• Embedding a File Explorer instance in a WinForms app form

  - by Unsliced

  My (C#, .NET 3.5) app generates files and, in addition to raising events that can be caught and reacted to, I want to display the target folder to the user in a form. The file-list is being shown within the same form as other information. I'm using an instance of the WebBrowser control (System.Windows.Forms.WebBrowser), then navigating to the folder. This shows some default view of the explorer window, with the file summary panel on the left and the files in the 'Tiles' (large icon and text) view. e.g. wb.Navigate(@"c:\path\to\folder\"); I'd like to suppress the panel and to view the file list in the Details view. The user can get to this via a right-click, context menu, but I'd like it to come up automatically. I'd rather not have to build my own TreeView, DataGridView or whatever; the WebBrowser control does all the updating and re-sorting and whatnot 'for free'. Does anybody have a better suggestion? A different control to use or some additional arguments to pass to the control? And if I could trap events (e.g. files being selected/renamed/double-clicked, etc.) then all the better!

• Java equivalent to VS solution file

  - by Chris

  I'm a C# guy trying to learn Java. I understand the syntax and the basic architecture of the Java platform, and have no problem doing smaller projects myself, but I'd really like to be able to download some open source projects to learn from the work of others. However, I'm running into a stumbling block that I can't seem to find any information on. When I download an open source .NET project, I can open the .sln file with visual studio and everything just loads. Sure, there's occasionally a missing reference or something, but there's really very little configuration required to get things going. I'm not sensing the same ease of use with Java. I'm using eclipse at the moment, and it feels like for every project I have to create a brand new Eclipse project using "create from existing source", and almost nothing compiles properly without significant reconfiguration. In the case of web projects, it's even worse, because Eclipse doesn't appear to support creating a web project from existing source. I have to create a standard Java project from source, then then apparently modify the project file to include the bindings for the web toolkit stuff to work properly. Assuming I want to be able to contribute to a project later on, I shouldn't have to be making such drastic changes to the file structure to get my IDE to a workable state. What am I missing?

• Having Uploadify e-mail a link to download the file

  - by kwek-kwek

  Uploadify is a jQuery plugin that allows the easy integration of a multiple (or single) file uploads on your website. It requires Flash and any backend development language. An array of options allow for full customization for advanced users, but basic implementation is so easy that even coding novices can do it. I wanted to ask if It is possible to sends out a link of a file that has just been uploaded wioth the e-mail notification of Uploadify.

• Cannot delete an image file that is shown in a listview

  - by Enrico

  Hello all, In my listview I show thumbnails of small images in a certain folder. I setup the listview as follows: var imageList = new ImageList(); foreach (var fileInfo in dir.GetFiles()) { try { var image = Image.FromFile(fileInfo.FullName); imageList.Images.Add(image); } catch { Console.WriteLine("error"); } } listView.View = View.LargeIcon; imageList.ImageSize = new Size(64, 64); listView.LargeImageList = imageList; for (int j = 0; j < imageList.Images.Count; j++) { var item = new ListViewItem {ImageIndex = j, Text = "blabla"}; listView.Items.Add(item); } The user can rightclick on an image in the listview to remove it. I remove it from the listview and then I want to delete this image from the folder. Now I get the error that the file is in use. Of course this is logical since the imagelist is using the file. I tried to first remove the image from the imagelist, but I keep on having the file lock. Can somebody tell me what I am doing wrong? Thanks!

• Render a Form from an XSLT file

  - by Russ Clark

  I've generated the following XSLT file, and have created a Form that will post to an ASP.Net MVC action called Home/ProcessRequest: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl" > <xsl:output method="html" indent="yes"/> <xsl:template match="/"> <html> <body> <xsl:value-of select="Employee/Name"/> <br /> <xsl:value-of select="Employee/ID"/> <form method="post" action="/Home/ProcessRequest?id=42"> <input id="Action" name="Action" type="radio" value="Approved"></input> Approved <br /> <input id="Action" name="Action" type="radio" value="Rejected"></input> Rejected <br /> <input type="submit" value="Submit"></input> </form> </body> </html> Here is my XML File: <Employee xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Name>Russ</Name> <ID>42</ID> </Employee> This works fine the way it is, but I need to change the id parameter in my from from a hard coded integer, to use the ID element from my XML file. Does anyone know how to do this?

• Perf4j Not Logging to Separate File

  - by Jehud

  I setup some stop watch calls in my code to measure some code blocks and all the messages are going into my primary log and not into the timing log. The perfStats.log file gets created just fine but all the messages go to the root log which I didn't think was supposed to happen according to the docs I've read. Is there something obvious I'm missing here? Example log4j.xml <!-- This file appender is used to output aggregated performance statistics --> <appender name="fileAppender" class="org.apache.log4j.FileAppender"> <param name="File" value="perfStats.log"/> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%m%n"/> </layout> </appender> <!-- Loggers --> <!-- The Perf4J logger. Note that org.perf4j.TimingLogger is the value of the org.perf4j.StopWatch.DEFAULT_LOGGER_NAME constant. Also, note that additivity is set to false, which is usually what is desired - this means that timing statements will only be sent to this logger and NOT to upstream loggers. --> <logger name="org.perf4j.TimingLogger" additivity="false"> <level value="INFO"/> <appender-ref ref="CoalescingStatistics"/> </logger> <root> <priority value="info"/> <appender-ref ref="STDOUT-DEBUG"/> </root>
