  • File upload and Download in a web app using struts2

    - by lakshmanan
    Hi In struts2 upload methods, can I choose where the uploaded file must be saved. I mean, all the examples in web ask me to store in WEB-INF which surely is not a good idea. I want to be able to store the uploaded file in any place in my disk. How should i do it? Can i do it with help of ServletContextAware interceptor ?

  • FileSystemWatcher vs Polling to watch for changes

    - by Jon Tackabury
    I need to setup an application that watches for files being created in a folder (locally or on a network drive) and I was wondering if anyone has any thoughts on whether the FileSystemWatcher or polling on a timer would be the best option. I have used both methods in the past, but not extensively. Have you run into any issues (performance, reliability... etc) with either method? I know there isn't a "right way" to do this, I'm just looking opinions.

  • Symfony - admin - FormFilter - is empty - i18n

    - by Mailo
    Hi, we are in admin generator in filters in field. What is the most clearest way to translate is empty label under form fields? I've solve it by own setWidgets and setWidgets in BaseFormFilterDoctrine witch extend the parent methods by translating that is empty( empty_label ). setWidgets - translate all *empty_label*s in form filter( for base filter class ) setWidget - translate *empty_label* for one filter field( for the extending filter class ) It works, but i think it's nasty. I am looking for something more clean

    - by Ali
    Hi guys I'm using microtime() function of php to tell how long certain snippets of code take to run I do this by taking the time before and after the snippet and subtracting them using microtime function. I got the following results though for the different snippets: 1 - 0.022976 2 - 0.003656 3 - -0.196361 4- 0.006563 5- 7.2E-5 6- 0.847695 7- 0.005092 8- 7.6E-5 9- 0.08024 The first numbers represent the snippt and the following the time taken...

  • can ServiceLocator.Current.GetInstance return null?

    - by mauricio076
    I have this piece of code (or similar) in many of our views: private IEventAggregator eventAggregator; Constructor() { eventAggregator = ServiceLocator.Current.GetInstance<IEventAggregator>(); ... } I read from this post that ServiceLocator.Current can throw NullReferenceException (bad thing on a constructor) but I was wondering if the GetInstance<() method can return null (or some other inconsistent object) making eventAggregator dangerous to use later in other methods. NOTE: I'm quite new to MVVM and WPF

  • SqlCommandBuilder.DeriveParameters(command) and IsNullable

    - by Andrey
    I have written an O/R database wrapper that generates some wrapper methods for stored procs it reads from the database. Now I need to produce some custom wrapper code if an input parameter of a stored proc is defaulted to NULL. The problem is - I get stored proc parameters using: SqlCommandBuilder.DeriveParameters(command) and it doesn't bring parameter defaults. Is there any way to look up those defaults? Are they stored anywhere in the database? BTW, I'm using SQL Server 2008

  • How can I split a string in Java?

    - by Sergio Tapia
    Imagine I have this string: string thing = "sergio|tapia|gutierrez|21|Boston"; In C# I could go: string[] Words = thing.Split('|'); Is there something similar in Java? I could use Substring and indexOf methods but it is horribly convoluted. I don't want that.

  • Webservice returns java.lang.reflect.InvocationTargetException

    - by Damian
    Hi, I am receiving the above message when making a request to a java webservice. We originally created a Java Console application and manually submitted an xml file. When running this as a Java Application the response is successfully created and displayed by using System.out.println. We are creating the web service by selecting the java file that contains the methods and choosing "create webservice" specifying the dynamic project that the webservice is to be created in and the methods to be exposed. What the application is doing is taking an xml file and unmarshalling this to an object using: public static Object unmarshalToObject(Class classToBeBound, String xmlRequest) { Object obj = new Object(); try { JAXBContext jc = JAXBContext.newInstance(classToBeBound); Unmarshaller um = jc.createUnmarshaller(); obj = um.unmarshal(new StringReader(xmlRequest)); } catch (Exception e) { e.printStackTrace() } return obj; } Some processing is carried out on the file and then an object is marshalled to xml as follows: public static String marshalToXML(Object data) { StringWriter sw = new StringWriter(); try { logger.info("Create new Marshall"); JAXBContext jc = JAXBContext.newInstance("ContextPathName"); logger.info("Marshalled to xmlObjects"); Marshaller marshaller = jc.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true); marshaller.marshal(data, sw); } catch (Exception e) { logException(logger, e); } return sw.toString(); } The following is the line of code that seems to be causing an issue as the logger displays the message prior to this: JAXBContext jc = JAXBContext.newInstance("ContextPathName"); The webservice never gets to the next line - the following is the body of the SOAP message: <soapenv:Fault> <faultcode>soapenv:Server.userException</faultcode> <faultstring>java.lang.reflect.InvocationTargetException</faultstring> <detail> <ns1:hostname xmlns:ns1="http://xml.apache.org/axis/">servername</ns1:hostname> </detail> </soapenv:Fault> I have added Try/Catch around this section of code even as far as looking for JAXBExceptions but this does not seem to catch anything - nor does the general exception. This issue does not occur when running the console application. The build path for this includes the following contents of sun\jwsdp-2.0\jaxb\lib: jaxb-api.jar jsr173_1.0_api.jar jaxb-impl.jar I have added these to the lib folder in the WEB-INF file of the dynamic project. I am running the webservice in JBuilder 2008 R2 and using SOAPUI to submit the request - this points to the wsdl generated when creating the webservice. If anyone has any help or ideas on how to solve this could they please reply - thanks for taking the time to read this post!

  • Does Objective-C support Mixin like Ruby?

    - by hacksignal
    In Ruby, there's Modules and you can extend a class by "mixing-in" the module. Module myModule def printone print "one" end end Class myClass extend myModule end theOne = myClass.new theOne.printone >> one In Objective-C, I find that I have a set of common methods that I want a number of Class to "inherit". What other ways can I achieve this without creating a common class and deriving all from that common class?

  • Windows Scheduler OR SQL Server Job for sending out digest e-mails

    - by wgpubs
    Will be sending out e-mails from an application on a scheduled basis. I have an EmailController in my ASP.NET MVC application with action methods, one for each kind of notification/e-mail, that will need to be called at different times during the week. Question: Is Windows Scheduler (running on a Server 2008 box) any better or worse than scheduling this via a SQL Server job? And why? Thanks

  • Python Class which checks input before passing to console (C) program

    - by Joseph Melettukunnel
    Hello, We are asked to write a web-frontend (in python) for a very complex (and old) console application, written in C. Since we have no access to the C Source Code, and we assume that there might be some unsafe methods, we'd like to check the input which will the passed to the console application. WebClient - Python Module - Console Application Do you have any suggestions or tips what we should check for? Right now we are only limiting the string length and filtering some (program specific) unallowed keywords. Thanks, Joseph EDIT: Will remove strings like %s because of format string attacks
