  • Confusion about maven-war-plugin and jetty-maven-plugin

    - by waxwing
    I am trying to get the run-exploded goal of the jetty-maven-plugin to work correctly. I find the documentation somewhat lacking on what I need to do to set this up. I believe I have a standard WAR-file setup. (The reason I wrote "believe" is that I find the maven-war-plugin documentation lacking as well.) When I build my webapp using maven package, I get the following in my target folder: classes maven-archiver surefire-reports test-classes tmp mywebapp-version mywebapp-version.war where mywebapp-version is the exploded war and mywebapp-version.war is the packaged one. So far so good (I think?). Now, running mvn jetty:run-exploded, it seems the default deploy folder is target/tmp/webapp/mywebapp-version.war/. This folder exists, but contains no files except for a webapp-cache.xml. This seems wrong to me. I also tried to actively set the webApp configuration element to ${project.build.directory}/mywebapp-version/, but run-exploded seems to ignore it (despite the documentation stating otherwise). What am I doing wrong? It looks as if I am missing something simple since no one else appears to be running into the same problem.

  • Simulate network failure on Android

    - by twk
    I've noticed when I switch from wifi to 3g on my Android phone that HTTP connections get killed. I'd like to simulate this error in an emulator for testing. Changing network speeds doesn't work, nor does turning on airplane mode (I've tried this on a 1.5 and a 2.1 AVD). Any ideas? I'm currently doing this by running my conns through Fiddler and manually killing them, but it would be nice to use something built into the Android dev system. Thanks

  • OCUnit & NSBundle

    - by kpower
    I created OCUnit test in concordance with "iPhone Development Guide". Here is the class I want to test: // myClass.h #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> @interface myClass : NSObject { UIImage *image; } @property (readonly) UIImage *image; - (id)initWithIndex:(NSUInteger)aIndex; @end // myClass.m #import "myClass.m" @implementation myClass @synthesize image; - (id)init { return [self initWithIndex:0]; } - (id)initWithIndex:(NSUInteger)aIndex { if ((self = [super init])) { NSString *name = [[NSString alloc] initWithFormat:@"image_%i", aIndex]; NSString *path = [[NSBundle mainBundle] pathForResource:name ofType:@"png"]; image = [[UIImage alloc] initWithContentsOfFile:path]; if (nil == image) { @throw [NSException exceptionWithName:@"imageNotFound" reason:[NSString stringWithFormat:@"Image (%@) with path \"%@\" for current index (%i) wasn't found.", [name autorelease], path, aIndex] userInfo:nil]; } [path release]; } return self; } - (void)dealloc { [image release]; [super dealloc]; } @end And my unit-test (LogicTests target): // myLogic.m #import <SenTestingKit/SenTestingKit.h> #import <UIKit/UIKit.h> #import "myClass.h" @interface myLogic : SenTestCase { } - (void)testTemp; @end @implementation myLogic - (void)testTemp { STAssertNoThrow([[myClass alloc] initWithIndex:0], "myClass initialization error"); } @end All necessary frameworks, "myClass.m" and images added to target. But on build I have an error: [[myClass alloc] initWithIndex:0] raised Image (image_0) with path \"(null)\" for current index (0) wasn't found.. myClass initialization error This code (initialization) works fine in application itself (main target) and later displays correct image. I've also checked my project folder (build/Debug-iphonesimulator/LogicTests.octest/) - there are LogicTests, Info.plist and necessary image files (image_0.png is one of them). What's wrong?

    I am using ant for my project and I have been trying to generate JUnit report using ant target. The problem I run in to is that at the end of the execution my TESTS-TestSuites.xml is empty.

  • DynamicJasper font encoding problem

    - by user266956
    Hello All, I'm new to DynamicJasper, I think it's a great project but for a few days I cannot run simple example which will display polish fonts properly. Details sections is generated without any problems automatically displaying polish letters like 'c z z a' etc. where title and column headers contain strange letters instead. I was trying to do the following, but it doesn't work: FastReportBuilder drb = new FastReportBuilder(); Font font = new Font(25, "SansSerif", "Helvetica", Font.PDF_ENCODING_CP1257_Baltic, true); Style titleStyle = new StyleBuilder(false).setFont(font).build(); DynamicReport dr = drb.addColumn("State", "state", String.class.getName(),30) .addColumn("Branch", "branch", String.class.getName(),30) .addColumn("Product Line", "productLine", String.class.getName(),50) .addGroups(2) .setTitle("November 2008 Zrebie aczc!") .setTitleStyle(titleStyle) .setSubtitle("This report was generated at " + new Date()) .setPrintBackgroundOnOddRows(true) .setUseFullPageWidth(true) .build(); JRDataSource ds = new JRBeanCollectionDataSource(this.simples); JasperPrint jp = DynamicJasperHelper.generateJasperPrint(dr, new ClassicLayoutManager(), ds); JasperViewer.viewReport(jp); //finally display the report report Any help would be highly appreciated as dynamicjasper forums seems to be dead and constantly spammed. Thanks in advance! Kris

  • problem with addressfilter in WCF

    - by Zé Carlos
    I've build my own WCF channel with all necessary stuff (like encoders, bindings, etc) to use it with ServiceHost. I just want to build the "channel stack" making no custumizations at "Service Model". To acomplish this, my encoder returns perfect ServiceModel.Messages with a XML infoset just like other channel does. Lets assume the following service implementation: [ServiceContract(Namespace = "http://MyNS")] public interface IService1 { [OperationContract(IsOneWay = true)] void dummy(); } public class Service1 : IService1 { public void dummy() { Console.WriteLine("In Service1:dummy()"); } } I used this service through other bindings and traced the following ServiceModel.Message contents (SOAP format): <s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing"> <s:Header> <a:Action s:mustUnderstand="1">http://MyNS/IService1/dummy</a:Action> <a:To s:mustUnderstand="1">amqp://localhost</a:To> </s:Header> <s:Body> <dummy xmlns="http://MyNS"></dummy> </s:Body> </s:Envelope> Then (just to debug) i changed my encoder to allways return this message. When i use my custom channel the WCF's runtime replay with an faul message telling: "The message with To '' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree." I read that the default EndPointDispatcher.AddressFilter simply looks to the "TO" header and delivery the message to corresponding service. This is happening with other bindings, why not happens with my custom channel too? Is there any way to i check what default AddressFilter is doing? Thanks

  • Understanding WordProcessingML tags and avoid unnecessary tags

    - by rithanyalaxmi
    Hi, I am using MS Word API to generate .docx which contains the data fetched from DB, in which i am applying the respective styles, fonts, symbols, etc. If the data fetched from the DB is quite huge, then there is a problem in displaying those data in the .docx file. I found that internally MS Word 2007 will write some content through tags which may not be needed to display the data. Hence i am figuring out what are the necessary MS Word tags needed when converting into a .xml file. So that i can avoid unnecessary tags and build only the respective tags which are needed to display the data. Hence i am planning to write my own .xml with the MS Word tags which are needed, than generating a .XML from .docx file My queries are:- 1) Whether it is right that the MS Word will generate some tags which may not be needed during the conversion of .docx to document.xml? That makes it heavy? If so what are the tags , so that i can avoid them when write by own .xml file. 2) Please send links to understand about the MS Word tags and its advantages, which tags are needed and which are not ? 3) Whether my approach to write a new .xml similar to document.xml (.docx conversion) is worthy one to go forward so that i can build the .xml with the tags i needed , so that i can improve the performance of the data display? Please shed some light into it and thanks in advance.. Thanks, Rithu

  • Xcode Link Frameworks "Relative to Current SDK" Doesn't Work When Mixing Mac Framework and iPhone St

    - by bl4th3rsk1t3
    I have a framework of code I maintain. It's got mac and iphone objective-c code. And some of it is shared. I'm not having any problems with code. It's a problem with Xcode. Let's just call my framework "AwesomeKit" for this problem. The first thing I did was create an xcode Framework project called "AwesomeKit". Add source files to it, link against the common mac frameworks: foundation, cocoa, carbon, etc. It compiles fine. Then, add a new "static library" target, let's call it "AwesomeKit-iPhone" and set the base SDK in the build settings to iphone device 3.1.3. The problem comes when I try to add "Existing Frameworks" to the AweseomKit-iPhone target. -First change the current build target to AwesomeKit-iPhone. -Right click on any group and select "Add Existing Frameworks..." -Choose UIKit.framework UIKit will immediately be highlighted red, as if it's missing. It is indeed missing because Xcode uses the "Relative SDK" setting from the "Mac OS 10.6" SDK. When it should be using it relative to the current target's base sdk iphone device 3.1.3. What the heck? Has anyone experienced this? This is really annoying.

  • Nhibernate: Don't fetch when accessing a child objects primary key

    - by thermal7
    Hi, Is there a way in NHibernate to get the foreign key of a child object, without fetching the child object? EG. I have User and UserRole. Can I access User.UserRole.UserRoleId without causing another hit on the database to retrieve UserRole? I realize I can set fetch mode to eager and this will stop it from hitting the database again, but theoretically this shouldn't be needed, as the User table has UserRoldId in it. Thanks in advance.

  • Determine whether .NET assemblies were built from the same source

    - by Clayton
    Does anyone know of a way to compare two .NET assemblies to determine whether they were built from the "same" source files? I am aware that there are some differencing utilities available, such as the plugin for Reflector, but I am not interested in viewing differences in a GUI, I just want an automated way to compare a collection of binaries to see whether they were built from the same (or equivalent) source files. I understand that multiple different source files could produce the same IL, and realise that the process would only be sensitive to differences in the IL, not the original source. The main obstacle to just comparing the byte streams for the two assemblies is that .NET includes a field called "MVID" (Module Version Identifier) the assembly. This appears to have a different value for every compilation, so if you build the same code twice the assembly will be different. A related question is, does anyone know how to force the MVID to be the same for each compilation? This would avoid us needing to have a comparison process that is insensitive to differences in the value of the MVID. A consistent MVID would be preferable, as this means that standard checksums could be used. The background behind this is that a third-party company is responsible for independently reviewing and signing off our releases, prior to us being permitted to release to Production. This includes reviewing the source code. They want to independently confirm that the source code we give them matches the binaries that we earlier built, tested and currently plan to deploy. We are looking for a process that allows them to independently build the system from the source we supply them with, and the compare the checksums against the checksums for the binaries we have tested. thanks

  • Forms Authentication logs out very quickly , locally works fine !!!

    - by user319075
    Hello to all, There's a problem that i am facing with my hosting company, I use a project that uses FormsAuthentication and the problem is that though it successfully logs in, it logs out VERY QUICKLY, and i don't know what could be the cause of that, so in my web.config file i added those lines: <authentication mode="Forms" > <forms name="Nadim" loginUrl="Login.aspx" defaultUrl="Default.aspx" protection="All" path="/" requireSSL="false"/> </authentication> <authorization> <deny users ="?" /> </authorization> <sessionState mode="StateServer" stateConnectionString="tcpip=localhost:42424" cookieless="false" timeout="1440"> </sessionState> and this is the code i use in my custom login page : protected void PasswordCustomValidator_ServerValidate(object source, ServerValidateEventArgs args) { try { UsersSqlDataSource.SelectParameters.Clear(); UsersSqlDataSource.SelectCommand = "Select * From Admins Where AdminID='" + IDTextBox.Text + "' and Password='" + PassTextBox.Text + "'"; UsersSqlDataSource.SelectCommandType = SqlDataSourceCommandType.Text; UsersSqlDataSource.DataSourceMode = SqlDataSourceMode.DataReader; reader = (SqlDataReader)UsersSqlDataSource.Select(DataSourceSelectArguments.Empty); if (reader.HasRows) { reader.Read(); if (RememberCheckBox.Checked == true) Page.Response.Cookies["Admin"].Expires = DateTime.Now.AddDays(5); args.IsValid = true; string userData = "ApplicationSpecific data for this user."; FormsAuthenticationTicket ticket1 = new FormsAuthenticationTicket(1, IDTextBox.Text, System.DateTime.Now, System.DateTime.Now.AddMinutes(30), true, userData, FormsAuthentication.FormsCookiePath); string encTicket = FormsAuthentication.Encrypt(ticket1); Response.Cookies.Add(new HttpCookie(FormsAuthentication.FormsCookieName, encTicket)); Response.Redirect(FormsAuthentication.GetRedirectUrl(IDTextBox.Text, RememberCheckBox.Checked)); //FormsAuthentication.RedirectFromLoginPage(IDTextBox.Text, RememberCheckBox.Checked); } else args.IsValid = false; } catch (SqlException ex) { ErrorLabel.Text = ex.Message; } catch (InvalidOperationException) { args.IsValid = false; } catch (Exception ex) { ErrorLabel.Text = ex.Message; } Also you will find that line of code: FormsAuthentication.RedirectFromLoginPage(IDTextBox.Text, RememberCheckBox.Checked); is commented because i thought there might be something wrong with the ticket when i log in , so i created it manually , every thing i know i tried but nothing worked, so does anyone have any idea what is the problem ? Thanks in advance, Baher.

  • How to get Autocomplete functionality without a control

    - by rahulchandran
    If you supply a list of strings to an edit control and set the autocomplete mode and source then you automatically get autocomplete functionality. My question is can I get the same functionality in .NET somewhere without a control. In other words I want something like: string[] ProgressivePartialMatch( string[] Strings, string MatchText ) and so I want the strings back that would have showed up in the autocomplete, so to speak.

  • java.lang.NoClassDefFoundError in command line

    - by Graham
    Hi, I'm developing an application in Eclipse and it runs fine from within Eclipse. The problem I'm having is that when I export it to a jar file and run it from the command line I get a NoClassDefFound error for javax.mail.internet. In both my project build path and class path I have included the activation.jar and mail.jar libraries required for me to use javax.mail.internet, and like I said it works fine from within Eclipse but not when I export it to a jar. If my build path has those files and so does my class path why would this not be working?

  • How do I get google protocol buffer messages over a socket connection without disconnecting the clie

    - by Dan
    Hi there, I'm attempting to send a .proto message from an iPhone application to a Java server via a socket connection. However so far I'm running into an issue when it comes to the server receiving the data; it only seems to process it after the client connection has been terminated. This points to me that the data is getting sent, but the server is keeping its inputstream open and waiting for more data. Would anyone know how I might go about solving this? The current code (or at least the relevant parts) is as follows: iPhone: Person *person = [[[[Person builder] setId:1] setName:@"Bob"] build]; RequestWrapper *request = [[[RequestWrapper builder] setPerson:person] build]; NSData *data = [request data]; AsyncSocket *socket = [[AsyncSocket alloc] initWithDelegate:self]; if (![socket connectToHost:@"192.168.0.6" onPort:6666 error:nil]){ [self updateLabel:@"Problem connecting to socket!"]; } else { [self updateLabel:@"Sending data to server..."]; [socket writeData:data withTimeout:-1 tag:0]; [self updateLabel:@"Data sent, disconnecting"]; //[socket disconnect]; } Java: try { RequestWrapper wrapper = RequestWrapper.parseFrom(socket.getInputStream()); Person person = wrapper.getPerson(); if (person != null) { System.out.println("Persons name is " + person.getName()); socket.close(); } On running this, it seems to hang on the line where the RequestWrapper is processing the inputStream. I did try replacing the socket writedata method with [request writeToOutputStream:[socket getCFWriteStream]]; Which I thought might work, however I get an error claiming that the "Protocol message contained an invalid tag (zero)". I'm fairly certain that it doesn't contain an invalid tag as the message works when sending it via the writedata method. Any help on the matter would be greatly appreciated! Cheers! Dan (EDIT: I should mention, I am using the metasyntactic gpb code; and the cocoaasyncsocket implementation)

  • Why does the the Java VM not recover after "Too many open files" errors?

    - by Michael
    In certain well-understood circumstances, our application will open too many sockets (database connections) and reach the maximum open files that the OS allows. We understand this; we are fixing the issue and also bumping up the limit. What we can't explain is why parts of our application don't recover even after the number of connections abates and we're well within the limit. In this case, it's an application running under Tomcat. When this happens, we first start seeing "Too many open files" errors: SEVERE: Socket accept failed java.net.SocketException: Too many open files at java.net.PlainSocketImpl.socketAccept(Native Method) at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:390) at java.net.ServerSocket.implAccept(ServerSocket.java:453) at java.net.ServerSocket.accept(ServerSocket.java:421) at org.apache.tomcat.util.net.DefaultServerSocketFactory.acceptSocket(DefaultServerSocketFactory.java:61) at org.apache.tomcat.util.net.JIoEndpoint$Acceptor.run(JIoEndpoint.java:310) at java.lang.Thread.run(Thread.java:619) Eventually, we start seeing NoClassDefFoundErrors inside an application thread that's trying to open HTTP connections: java.lang.NoClassDefFoundError: org/apache/commons/httpclient/protocol/ControllerThreadSocketFactory at org.apache.commons.httpclient.protocol.DefaultProtocolSocketFactory.createSocket(DefaultProtocolSocketFactory.java:128) at org.apache.commons.httpclient.HttpConnection.open(HttpConnection.java:707) at org.apache.commons.httpclient.MultiThreadedHttpConnectionManager$HttpConnectionAdapter.open(MultiThreadedHttpConnectionManager.java:1349) [...] Caused by: java.lang.ClassNotFoundException: org.apache.commons.httpclient.protocol.ControllerThreadSocketFactory at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1387) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1233) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) ... 8 more When the errant connections go away, the server starts accepting connections again, and everything seems ok, but we're left with the latter error constantly being spewed to stderr. Although the application typically logs unloaded classes to stdout, I don't see any such logs just before, during or after the "Too many open files" errors. My initial theory was that the Hotspot JVM would unload seemingly unused classes when it encounters "Too many open files," but if so, it doesn't log the fact. I'd also expect it to recover if that were the case. Platform details: Java(TM) SE Runtime Environment (build 1.6.0_14-b08) Java HotSpot(TM) 64-Bit Server VM (build 14.0-b16, mixed mode) Apache Tomcat Version 6.0.18

However, as far as I can tell, I have the latest version of Java: ~/apache-cassandra-incubating-0.4.1-src > java -version java version "1.6.0_13" Java(TM) SE Runtime Environment (build 1.6.0_13-b03-211) Java HotSpot(TM) 64-Bit Server VM (build 11.3-b02-83, mixed mode) ~/apache-cassandra-incubating-0.4.1-src > javac -version javac 1.6.0_13 ~/Downloads/apache-cassandra-incubating-0.4.1-src > echo $JAVA_HOME /System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home Any ideas on what I'm doing wrong?

  • How do I create midi data to trigger an Ultrabeat pattern in Logic?

    - by user289581
    I've made some Ultrabeat patterns but I can't figure out how to trigger them. I make the pattern on C-1, then I go back to the arrange window and hit record and then hit C1 on my keyboard, and it doesn't play the pattern, it just plays a single note. I have Pattern Mode enabled on Ultrabeat and I'm using a one-shot trigger but I can't seem to trigger my pattern to play at all. What am I doing wrong?

  • Enable iPhone accelerometer while screen is locked..

    - by kamziro
    So apparently it is possible to keep the processor going processing stuff while the screen is locked, as indicated here: http://stackoverflow.com/questions/1551712/running-iphone-apps-while-in-sleep-mode However, after testing with the example code, UIAccelerometer will just stop giving value as soon as the device is locked pronto. Is there a way to force otherwise?

  • HTML APIs for touch devices?

    - by askvictor
    What HTML APIs are available for touch screen devices (e.g. tablet PCs)? I notice that GMail's iPad interface (and other mobile interfaces) doesn't scroll down in a normal web browser (pretending to be an iPad via a user-agent hack). How can one access this API on a PC? I have a school full of tablet PCs that aren't wonderful in tablet mode due to lack of application support, but there looks to be an increasing number of web-based apps that will fill this gap.

  • How to setup Erlang + Emacs with erlang.el?

    - by Jonas
    I have downloaded and installed Erlang and EmacsW32. But how do I use erlang.el in Emacs? Where do I place it or install it? I have read Erlang/OTP R13B04 documentation and Erlang mode for Emacs documentation but I haven't found any information about how to set up it.

  • practical security ramifications of increasing WCF clock skew to more than an hour

    - by Andrew Patterson
    I have written a WCF service that returns 'semi-private' data concerning peoples name, addresses and phone numbers. By semi-private, I mean that there is a username and password to access the data, and the data is meant to be secured in transit. However, IMHO noone is going to expend any energy trying to obtain the data, as it is mostly available in the public phone book anyway etc. At some level, the security is a bit of security 'theatre' to tick some boxes imposed on us by government entities. The client end of the service is an application which is given out to registered 'users' to run within their own IT setups. We have no control over the IT of the users - and in fact they often tell us to 'go jump' if we put too many requirements on their systems. One problem we have been encountering is numerous users that have system clocks that are not accurate. This can either be caused by a genuine slow/fast clocks, or more than likely a timezone or daylight savings zone error (putting their machine an hour off the 'real' time). A feature of the WCF bindings we are using is that they rely on the notion of time to detect replay attacks etc. <wsHttpBinding> <binding name="normalWsBinding" maxBufferPoolSize="524288" maxReceivedMessageSize="655360"> <reliableSession enabled="false" /> <security mode="Message"> <message clientCredentialType="UserName" negotiateServiceCredential="false" algorithmSuite="Default" establishSecurityContext="false" /> </security> </binding> </wsHttpBinding> The inaccurate client clocks cause security exceptions to be thrown and unhappy users. Other than suggesting users correct their clocks, we know that we can increase the clock skew of the security bindings. http://www.danrigsby.com/blog/index.php/2008/08/26/changing-the-default-clock-skew-in-wcf/ My question is, what are the real practical security ramifications of increasing the skew to say 2 hours? If an attacker can perform some sort of replay attack, why would a clock skew window of 5 minutes be necessarily safer than 2 hours? I presume performing any attack with security mode of 'message' requires more than just capturing some data at a proxy and sending the data back in again to 'replay' the call? In a situation like mine where data is only 'read' by the users, are there indeed any security ramifications at all to allowing 'replay' attacks?
