  • multiple FileSystemWatchers to monitor files on local system?

    - by Jason Crowes
    We're writing a text editor like tool for our internal accounting package system that has actions that can be done by our own Xml language specs. These macro commands are specified in Xml files and we need the ability to monitor if files openned have bean modified externally. The only problem is that there maybe 20-30 files with different paths openned at any one time. Would it be good to use multiple FileSystemWatchers for this scenario? Or would it be better to monitor the root drive and catch specific events that match an open file in the editor (though lots of events could be raised). Some are local drives (C,D,E) others are their network drives (U,X,G,H). Files are quite chunky too about 300-400Kb.

  • Drill down rss reader iphone

    - by bing
    Hi everyone, I have made a simple rss reader. The app loads an xml atom file in an array. Now I have added categories to my atom feed, which are first loaded in the array What is the best way to add drill down functionality programmatically. Now only the categories are loaded into the array and displayed. This is the implementation code ..... loading xml file <snip> ..... - (void)parserDidStartDocument:(NSXMLParser *)parser { NSLog(@"found file and started parsing"); } - (void)parser:(NSXMLParser *)parser parseErrorOccurred:(NSError *)parseError { NSString * errorString = [NSString stringWithFormat:@"Unable to download story feed from web site (Error code %i )", [parseError code]]; NSLog(@"error parsing XML: %@", errorString); UIAlertView * errorAlert = [[UIAlertView alloc] initWithTitle:@"Error loading content" message:errorString delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; [errorAlert show]; } - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{ //NSLog(@"found this element: %@", elementName); currentElement = [elementName copy]; if ([elementName isEqualToString:@"entry"]) { // clear out our story item caches...

  • having trouble with jpa, looks to be reading from cache when told to ignore

    - by jeff
    i'm using jpa and eclipselink. it says version 2.0.2.v20100323-r6872 for eclipselink. it's an SE application, small. local persistence unit. i am using a postgres database. i have some code the wakes up once per second and does a jpa query on a table. it's polling to see whether some fields on a given record change. but when i update a field in sql, it keeps showing the same value each time i query it. and this is after waiting, creating a new entitymanager, and giving a query hint. when i query the table from sql or python, i can see the changed field. but from within my jpa query, once i've read the value, it never changes in later executions of the query -- even though the entity manager has been recreated. i've tried telling it to not look in the cache. but it seems to ignore that. very puzzling, can you help please? here is the method. i call this once every 3 seconds. the tgt.getTrlDlrs() println shows me i get the same value for this field on every call of the method ("value won't change"). even if i change the field in the database. when i query the record from outside java, i see the change right away. also, if i stop the java program and restart it, i see the new value printed out immediately: public void exitChk(EntityManagerFactory emf, Main_1 mn){ // this will be a list of the trade close targets that are active List<Pairs01Tradeclosetgt> mn_res = new ArrayList<Pairs01Tradeclosetgt>(); //this is a list of the place number in the array list above //of positions to close ArrayList<Integer> idxsToCl = new ArrayList<Integer>(); EntityManager em = emf.createEntityManager(); em.getTransaction().begin(); em.clear(); String qryTxt = "SELECT p FROM Pairs01Tradeclosetgt p WHERE p.isClosed = :isClosed AND p.isFilled = :isFilled"; Query qMn = em.createQuery(qryTxt); qMn.setHint(QueryHints.CACHE_USAGE, CacheUsage.DoNotCheckCache); qMn.setParameter("isClosed", false); qMn.setParameter("isFilled", true); mn_res = (List<Pairs01Tradeclosetgt>) qMn.getResultList(); // are there any trade close targets we need to check for closing? if (mn_res!=null){ //if yes, see whether they've hit their target for (int i=0;i<mn_res.size();i++){ Pairs01Tradeclosetgt tgt = new Pairs01Tradeclosetgt(); tgt = mn_res.get(i); System.out.println("value won't change:" + tgt.getTrlDlrs()); here is my entity class (partial): @Entity @Table(name = "pairs01_tradeclosetgt", catalog = "blah", schema = "public") @NamedQueries({ @NamedQuery(name = "Pairs01Tradeclosetgt.findAll", query = "SELECT p FROM Pairs01Tradeclosetgt p"), @NamedQuery(name = "Pairs01Tradeclosetgt.findByClseRatio", query = "SELECT p FROM Pairs01Tradeclosetgt p WHERE p.clseRatio = :clseRatio")}) public class Pairs01Tradeclosetgt implements Serializable { private static final long serialVersionUID = 1L; @Id @Basic(optional = false) @Column(name = "id") @SequenceGenerator(name="pairs01_tradeclosetgt_id_seq", allocationSize=1) @GeneratedValue(strategy=GenerationType.SEQUENCE, generator = "pairs01_tradeclosetgt_id_seq") private Integer id; and my persitence unit: <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> <persistence-unit name="testpu" transaction-type="RESOURCE_LOCAL"> <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> <class>mourv02.Pairs01Quotes</class> <class>mourv02.Pairs01Pair</class> <class>mourv02.Pairs01Trderrs</class> <class>mourv02.Pairs01Tradereq</class> <class>mourv02.Pairs01Tradeclosetgt</class> <class>mourv02.Pairs01Orderstatus</class> <properties> <property name="javax.persistence.jdbc.url" value="jdbc:postgresql://192.168.1.80:5432/blah"/> <property name="javax.persistence.jdbc.password" value="secret"/> <property name="javax.persistence.jdbc.driver" value="org.postgresql.Driver"/> <property name="javax.persistence.jdbc.user" value="noone"/> </properties> </persistence-unit> </persistence>

  • Intro to Sessions in ASP.Net

    Sessions are used to pass the value from one page to another with no effort from the user. With a session, if the user inputs values on the original page and you need to access them on another page, you can retrieve the values stored in the session without making the user submit those values again. Sessions are important to any user-related authentication (if you're using the https protocol), user-related validation and customization of visitor experiences in your website. This tutorial will use Visual Basic to illustrate ASP.NET sessions, though the code can be converted to equivalent C# code...

  • Catching an error for a child resource in Ruby on Rails

    - by randombits
    What is the best way to add errors to render if a child resource is really what's having issues and not the parent resource? In english what I mean is the following.. imagine the following code: @foo = Foo.new foochild = Foochild.new // break foochild somehow @foo << foochild @foo.save now when I do: format.xml { render :xml => @foo.errors } I don't get anything about how foochild broke, meaning the error message is useless to the user. How does one go about fixing this?

  • How do I set up Scala plugin for NetBeans to copy the Scala runtime library?

    - by Alexey Romanov
    Versions: NetBeans 6.8, Scala Kit 0.16.1 When I compile my project, I get the following output: init: deps-jar: Compiling 2 source files to F:\MyProgramming\NorvigSpellChecker\build\classes compile: Created dir: F:\MyProgramming\NorvigSpellChecker\dist Building jar: F:\MyProgramming\NorvigSpellChecker\dist\NorvigSpellChecker.jar Not copying the libraries. To run this application from the command line without Ant, try: java -jar "F:\MyProgramming\NorvigSpellChecker\dist\NorvigSpellChecker.jar" jar: BUILD SUCCESSFUL (total time: 3 seconds) Of course, the libraries should be copied, so I can't actually run it by using this command line. I don't see any options to copy the library in the project configuration. The plugin uses Ant for building, but I don't have any experience with it; presumably it should be easy enough to tell Ant to copy the libraries. Here is build-impl.xml, what should I do in build.xml?

  • php: simplexml exception retry

    - by exceptionhandlingnoob
    I am querying an API using SimpleXML which will occasionally fail for reasons unknown. I would like to have the script retry up to 5 times. How can I do this? I assume it has something to do with wrapping the object in a try/catch, but I'm not very experienced with this -- have tried to read the manual on exception handling but am still at a loss. Thanks for any help :) // set up xml handler $xmlstr = file_get_contents($request); $xml = new SimpleXMLElement($xmlstr); Here is the error message I am receiving: [function.file-get-contents]: failed to open stream: HTTP request failed!

  • Nokogiri Not Parsing File

    - by Jesse J
    I'm using Nokogiri to parse pepXML files from different peptide search engines. I have two pepXML files, both of which appear, inasmuch as I can tell, to be of correct format, and puts Nokogiri::XML(IO.read(file)) will output the whole XML file for both files. The problem is, doc.xpath("any valid xpath") will parse the tag from one of the files, but not the other. No errors are given, so I have no idea why it won't parse. Anyone know of any reasons why Nokogiri wouldn't parse something out?

    In C# ASP.NET, if we have the characters < or in a string. Do we need to escape it like: string a = "\<test\>abcdef\</test\>" because this string will be send to an external method via webservices. And in that method, it will be converted to a some kind of xml file. contentHtml = "<?xml version=\"1.0\" encoding=\"utf-16\"?>" + contentHtml; content_ws.AddContent(contentHtml); //AddContent() method is a external method (via webservices) Thx for help

  • Hibernate bug using Oracle?

    - by Lothar
    Hello, I've got the problem, that I use a property in the persistence.xml which forces Hibernate to look only for tables in the given schema. <property name="hibernate.default_schema" value="FOO"/> Because we are using now 4 different schemas the actual solution is to generate 4 war files with a modified persistence.xml. That not very elegant. Does anybody know, how I can configure the schema with a property or by manipulation the JDBC connection string? I'm using Oracle 10g, 10_2_3 Patch. Thanks a lot.

  • REST - why we need million urls and different HTTP request?

    - by Andre
    I asked this question. But I still don't understand why we need to utilize different HTTP requests: DELETE/PUT/POST/GET in order to build nice API Wouldn't it be a lot simpler to pass all information in request parameters and have a SINGLE ENTRY-POINT for your api?: GET www.example.com/api?id=1&method=delete&returnformat=JSON GET www.example.com/api?id=1&method=delete&returnformat=XML or POST www.example.com/api {post data: id=1&method=delete&returnformat=JSON} POST www.example.com/api {post data: id=1&method=delete&returnformat=XML} and then - we can handle all methods and data internally without the need for hundreds of urls... how would you call this type of API - It's not REST apparently, it's not SOAP. then - what is it? UPDATE I'm not proposing any new standards here. I merely asking a question in order to better understand why web services work the way they work.

  • Export Multiple Sheets to Excel Through Browser

    - by ProfK
    I need to export multiple data tables to Excel on the clients machine, each to their own sheet. If it was just one sheet, I'd use the Excel/csv content type, but I've heard something about an XML format that can represent an entire workbook. I don't want to go down the Packaging and .xlsx route, so I need standard .xls. Our bug tracker, Gemini, used to have an export function that produced an XML file that Excel automatically opened as a multi-sheet workbook, but I can't find it. Is there still such a mechanism, and where can I find that schema?

  • Manage duplicate jar files using ant and ivy.

    - by lawardy
    HI, I am using ant build script to build my java app and utilizing Ivy to manage its dependency. As my application is dependent/subset of other application(Main App), when running it, I set the classpath to point to lib jars of the Main App. As I tried to build the kit using ant and ivy, it includes/retrieve all the jars that is required as specified in ivy.xml The problem is, some of the jar files are duplicated with with jars file in the main app folders. Is there a way to set the classpath in build.xml to ignore retrieving jar files that already exist in the main app's lib folder. Thanks

  • Petstore using Java EE 6 ? Almost!

    - by arungupta
    Antonio Goncalves, a Java Champion, JUG leader, and a well-known author, has started building a Petstore-like application using Java EE 6. The complete end-to-end sample application will build a eCommerce website and follows the Java EE 6 design principles of simple and easy-to-use to its core. Its using several technologies from the platform such as JPA 2.0, CDI 1.0, Bean Validation 1.0, EJB Lite 3.1, JSF 2.0, and JAX-RS 1.1. The two goals of the project are: • use Java EE 6 and just Java EE 6 : no external framework or dependency • make it simple : no complex business algorithm The application works with GlassFish and JBoss today and there are plans to add support for TomEE. Download the source code from github.com/agoncal/agoncal-application-petstore-ee6. And feel free to fork if you want to use a fancy toolkit as the front-end or show some nicer back-end integration. Some other sources of similar end-to-end applications are: • Java EE 6 Tutorial • Java EE 6 Galleria • Java EE 6 Hands-on Lab

  • How do I construct a request for a WCF http post call?

    - by James Hay
    I have a really simple service that I'm messing about with defined by: [OperationContract] [WebInvoke(UriTemplate = "Review/{val}", RequestFormat = WebMessageFormat.Xml, Method = "POST", BodyStyle=WebMessageBodyStyle.Bare)] void SubmitReview(string val, UserReview review); UserReview is, at the moment, a class with no properties. All very basic. When I try and test this in Fiddler I get a bad request status (400) message. I'm trying to call the service using the details: POST http://127.0.0.1:85/Service.svc/Review/hello Headers User-Agent: Fiddler Content-Type: application/xml Host: 127.0.0.1:85 Content-Length: 25 Body <UserReview></UserReview> I would think i'm missing something fairly obvious.

  • Define keyref selector based on element type in XPath

    - by Robert Sirre
    Let's say I have an XML file that will look like this: <a> <b d="value1"/> <c d="value2"/> </a> In the XSD file that defines the structure of this XML file I defined the elements by name 'b' and 'c' to be of the same type (and the type requires attribute 'd'). Let's say that I want to make a keyReference of all elements of the type that both 'b' and 'c' are, is there any way in XPath to do this? At the definition of the type of 'a' I would expect something like this: <xs:keyref name="myReferenceName" refer="keyToReferTo"> <xs:selector xpath="[@type='typenameof elements b and c?']"/> <xs:field xpath="@d"/> </xs:keyref> Is something like this possible, or is XPath, even in the XSD, schema-unaware?
