  • Convert XML attributes to a Dictionary in Linq to XML

    - by NateD
    I've got a program that needs to convert two attributes of a particular tag to the key and value of an Dictionary<int,string>. The XML looks like this: (fragment) <startingPoint coordinates="1,1" player="1" /> and so far my LINQ looks something like this: XNamespace ns = "http://the_namespace"; var startingpoints = from sp in xml.Elements(ns+"startingPoint") from el in sp.Attributes() select el.Value; Which gets me a nice IEnumerable full of things like "1,1" and "1", but there should be a way to adapt something like this answer to do attributes instead of elements. Little help please? Thank you!

  • .NET XML Serialization without <?xml> root node

    - by Graphain
    Hi, I'm trying to generate XML like this: <?xml version="1.0"?> <!DOCTYPE APIRequest SYSTEM "https://url"> <APIRequest> <Head> <Key>123</Key> </Head> <ObjectClass> <Field>Value</Field </ObjectClass> </APIRequest> I have a class (ObjectClass) decorated with XMLSerialization attributes like this: [XmlRoot("ObjectClass")] public class ObjectClass { [XmlElement("Field")] public string Field { get; set; } } And my really hacky intuitive thought to just get this working is to do this when I serialize: ObjectClass inst = new ObjectClass(); XmlSerializer serializer = new XmlSerializer(inst.GetType(), ""); StringWriter w = new StringWriter(); w.WriteLine(@"<?xml version=""1.0""?>"); w.WriteLine("<!DOCTYPE APIRequest SYSTEM"); w.WriteLine(@"""https://url"">"); w.WriteLine("<APIRequest>"); w.WriteLine("<Head>"); w.WriteLine(@"<Field>Value</Field>"); w.WriteLine(@"</Head>"); XmlSerializerNamespaces ns = new XmlSerializerNamespaces(); ns.Add("", ""); serializer.Serialize(w, inst, ns); w.WriteLine("</APIRequest>"); However, this generates XML like this: <?xml version="1.0"?> <!DOCTYPE APIRequest SYSTEM "https://url"> <APIRequest> <Head> <Key>123</Key> </Head> <?xml version="1.0" encoding="utf-16"?> <ObjectClass> <Field>Value</Field> </ObjectClass> </APIRequest> i.e. the serialize statement is automatically adding a <?xml root element. I know I'm attacking this wrong so can someone point me in the right direction? As a note, I don't think it will make practical sense to just make an APIRequest class with an ObjectClass in it (because there are say 20 different types of ObjectClass that each needs this boilerplate around them) but correct me if I'm wrong.

  • Could not locate compojure in classpath

    - by Xian
    I am trying the various Getting started examples and I can get a basic hello world example working with basic HTML in the route as such (ns hello-world (:use compojure.core ring.adapter.jetty) (:require [compojure.route :as route])) (defroutes example (GET "/" [] "<h1>Hello World Wide Web!</h1>")) (run-jetty example {:port 8080}) But when I attempt to use the html helpers like so (ns hello-world (:use compojure ring.adapter.jetty) (:require [compojure.route :as route])) (defroutes example (GET "/" (html [:h1 "Hello World"]))) (run-jetty example {:port 8080}) Then I get the following error [null] Exception in thread "main" java.io.FileNotFoundException: Could not locate compojure__init.class or compojure.clj on classpath: (core.clj:1)

  • EntityManagerFactory error on Websphere

    - by neverland
    I have a very weird problem. Have an application using Hibernate and spring.I have an entitymanger defined which uses a JNDI lookup .It looks something like this <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="persistenceUnitName" value="ConfigAPPPersist" /> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> <property name="showSql" value="true" /> <property name="generateDdl" value="false" /> <property name="databasePlatform" value="org.hibernate.dialect.Oracle9Dialect" /> </bean> </property> </bean> <bean id="dataSource" class="org.springframework.jdbc.datasource.WebSphereDataSourceAdapter"> <property name="targetDataSource"> <bean class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="jdbc/pmp" /> </bean> </property> </bean> This application runs fine in DEV. But when we move to higher envs the team that deploys this application does it successfully initially but after a few restarts of the application the entitymanager starts giving this problem Caused by: javax.persistence.PersistenceException: [PersistenceUnit: ConfigAPPPersist] Unable to build EntityManagerFactory at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:677) at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:132) at org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean.createNativeEntityManagerFactory(LocalContainerEntityManagerFactoryBean.java:224) at org.springframework.orm.jpa.AbstractEntityManagerFactoryBean.afterPropertiesSet(AbstractEntityManagerFactoryBean.java:291) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1368) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1334) ... 32 more Caused by: org.hibernate.MappingException: **property mapping has wrong number of columns**: com.***.***.jpa.marketing.entity.MarketBrands.$performasure_j2eeInfo type: object Now you would say this is pretty obvious the entity MarketBrands is incorrect. But its not it maps to the table just fine. And the same code works on DEV. Also the jndi cannot be incorrect since it deploys and works fine initially but throws uo this error after a restart. This is weird and not very logical. But if someone has faced this or has any idea on what might be causing this Please!! help The persistence.xml for the persitence unit has very little <?xml version="1.0" encoding="UTF-8"?> <persistence 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" version="1.0"> <persistence-unit name="ConfigAPPPersist"> <!-- commented code --> </persistence-unit> </persistence>

  • Cannot parse persistence unit from class path resource

  • Query an XmlDocument without getting a 'Namespace prefix is not defined' problem

    - by Dan Revell
    I've got an Xml document that both defines and references some namespaces. I load it into an XmlDocument object and to the best of my knowledge I create a XmlNamespaceManager object with which to query Xpath against. Problem is I'm getting XPath exceptions that the namespace "my" is not defined. How do I get the namespace manager to see that the namespaces I am referencing are already defined. Or rather how do I get the namespace definitions from the document to the namespace manager. Furthermore tt strikes me as strange that you have to provide a namespace manager to the document which you create from the documents nametable in the first place. Even if you need to hardcode manual namespaces why can't you add them directly to the document. Why do you always have to pass this namespace manager with every single query? What can't XmlDocument just know? The Code: XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(programFiles + @"Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\FEATURES\HfscBookingWorkflow\template.xml"); XmlNamespaceManager ns = new XmlNamespaceManager(xmlDoc.NameTable); XmlNode referenceNode = xmlDoc.SelectSingleNode("/my:myFields/my:ReferenceNumber", ns); referenceNode.InnerXml = this.bookingData.ReferenceNumber; XmlNode titleNode = xmlDoc.SelectSingleNode("/my:myFields/my:Title", ns); titleNode.InnerXml = this.bookingData.FamilyName; ... The Xml: <?xml version="1.0" encoding="UTF-8" ?> <?mso-infoPathSolution name="urn:schemas-microsoft-com:office:infopath:Inspection:-myXSD-2010-01-15T18-21-55" solutionVersion="1.0.0.104" productVersion="12.0.0" PIVersion="1.0.0.0" ?> <?mso-application progid="InfoPath.Document" versionProgid="InfoPath.Document.2"?> - <my:myFields xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xhtml="http://www.w3.org/1999/xhtml" xmlns:my="http://schemas.microsoft.com/office/infopath/2003/myXSD/2010-01-15T18:21:55" xmlns:xd="http://schemas.microsoft.com/office/infopath/2003"> <my:DateRequested xsi:nil="true" /> <my:DateVisited xsi:nil="true" /> <my:ReferenceNumber /> <my:FireCall>false</my:FireCall> ...

  • Connection error in java website. Tnsping shows that the service is running

    - by user1439090
    I have a java website application running in windows 7 which uses oracle database for its functionalities. The database has default SID name orcl.

  • Flex Spark DropDownList selectedItem didn't update after dataProvider changed

    - by Candy Chiu
    I have two dataProvider's for one DropDownList. The following code can be compiled and run. <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" creationComplete="flipLast()" minWidth="955" minHeight="600"> <fx:Script> <![CDATA[ import mx.collections.ArrayCollection; public function flipLast():void { if( last ) { list.dataProvider = dp1; list.selectedItem = "Flex"; } else { list.dataProvider = dp2; list.selectedItem = "Catalyst"; } last = !last; } public var last:Boolean = true; public var dp1:ArrayCollection = new ArrayCollection( [ "Flex", "Air" ] ); public var dp2:ArrayCollection = new ArrayCollection( [ "Catalyst", "FlashBuilder" ] ); ]]> </fx:Script> <s:VGroup> <s:DropDownList id="list" requireSelection="true" /> <s:Label id="listSelectedItem" text="{list.selectedItem}" /> <s:Label id="listSelectedIndex" text="{list.selectedIndex}" /> <s:Button label="Flip" click="flipLast()" /> </s:VGroup> </s:Application> Scenario 1: dataProvider updated, but selectedIndex is the same. At startup: [ listSelectedItem=Flex, listSelectedIndex=1 ]. Click Flip: dataProvider is updated, but still [ listSelectedItem=Flex, listSelectedIndex=1 ]. Scenario 2: dataProvider updated, selectedIndex is also updated. At startup: [ listSelectedItem=Flex, listSelectedIndex=1 ]. Select Air from list: [ listSelectedItem=Air, listSelectedIndex=2 ]. Click Flip: dataProvider is updated, but still [ listSelectedItem=Catalyst, listSelectedIndex=1 ]. Seems to me that selectedItem is driven by selectedIndex. selectedItem updates only when selectedIndex updates. Shouldn't selectedItem be updated when dataProvider is updated? Is binding to selectedItem flawed?

  • Starting ActiveMQ message listener in Tomcat?

    - by Nick Swarr
    I've created an ActiveMQ MessageListener and configured it using Spring. I'm hosting the listener in Tomcat. When I start up the web application (that features only the listener), should the listener automatically start? Or do I need additional configuration? Here's what I have. First, updated the web.xml to allow spring to configure itself on startup, <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/spring/applicationContext.xml</param-value> </context-param> </web-app> Then I created the applicationContext.xml to configure the ActiveMQ listener, <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:amq="http://activemq.apache.org/schema/core" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <context:annotation-config /> <context:component-scan base-package="com.somepackage"/> <context:property-placeholder location="classpath:env.properties"/> <bean id="jmsFactory" class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL" value="tcp://localhost:61616" /> </bean> <bean id="documentListener" class="com.somepackage.SomeListener" /> <bean id="container" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="cachingConnectionFactory"/> <property name="messageListener" ref="documentListener"/> <property name="destinationName" value="STOCKS.MSFT" /> </bean> <bean id="cachingConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory"> <property name="targetConnectionFactory" ref="jmsFactory" /> <property name="sessionCacheSize" value="1" /> </bean> </beans> And that's it. Based on what I've seen around the web, I can't tell if that's all I need? Maybe I need some other configuration in Tomcat to kick off the listener?

  • Empty namespace using Linq Xml

    - by porum
    I'm trying to create a sitemap using Linq to Xml, but am getting an empty namespace attribute, which I would like to get rid of. e.g. XNamespace ns = "http://www.sitemaps.org/schemas/sitemap/0.9"; XDocument xdoc = new XDocument(new XDeclaration("1.0", "utf-8", "true"), new XElement(ns + "urlset", new XElement("url", new XElement("loc", "http://www.example.com/page"), new XElement("lastmod", "2008-09-14")))); The result is ... <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <url xmlns=""> <loc>http://www.example.com/page</loc> <lastmod>2008-09-14</lastmod> </url> </urlset> I would rather not have the xmlns="" on the url element. I can strip it out using Replace on the final xdoc.ToString(), but is there a more correct way?

  • How do I apply a servlet filter when serving an HTML page directly?

    - by Philippe Beaudoin
    First off, I'm using Google AppEngine and Guice, but I suspect my problem is not related to these. When the user connect to my (GWT) webapp, the URL is a direct html page. For example, in development mode, it is: http://127.0.0.1:8888/Puzzlebazar.html?gwt.codesvr=127.0.0.1:9997. Now, I setup my web.xml in the following way: <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name>PuzzleBazar</display-name> <!-- Default page to serve --> <welcome-file-list> <welcome-file>Puzzlebazar.html</welcome-file> </welcome-file-list> <filter> <filter-name>guiceFilter</filter-name> <filter-class>com.google.inject.servlet.GuiceFilter</filter-class> </filter> <filter-mapping> <filter-name>guiceFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- This Guice listener hijacks all further filters and servlets.

I tried things like "*.html*" or <url-pattern>*</url-pattern> but to no avail. Any idea how I should do this?

  • How to deal with presence or not of xml namespaces using xslt.

    - by Mycol
    I have some XML/TEI documents, and i'm writing an XSLT 2.0 to extract their content. Almost all TEI documents has no namespace, but one has the default namespace (xmlns="http://www.tei-c.org/ns/1.0"). So all documents has the same aspect, with unqulified tags like <TEI> or <teiHeader>, but if I try to extract the content, all works with "non-namespaced-documents", but nothing (of course) is extracted from the namespaced-document. So i used the attribute xpath-default-namespace="http://www.tei-c.org/ns/1.0" and now (of course) the only document working is the namespaced one. I can't edit documents at all, so what I'm asking is if there's a way to change dynamically the xpath-default-namespace in order to make work xpaths like //teiHeader both with namespaced and non-namespaced documents

  • Difference between halo and mx namespace

    - by Andree
    Hi there ! As far as I know, the support for library://ns.adobe.com/flex/halo namespace has been dropped, and now we have to use library://ns.adobe.com/flex/mx instead (reference). Can someone provide if there's any difference between the two namespaces? I am just starting to learn Flex and this change make me confused. For example, if I have an <mx:Tree> tag in my mxml document, the compiler complains that <mx:Tree> could not be resolved to a component implementation. But if I change my mx namespace to use the old one instead (halo), it successfully compiled without error. Thanks. Andree Updated: By the way, I use Flex SDK command line compiler in Windows. mxmlc --version Version 4.0.0 build 10485

  • Hadoop in a RESTful Java Web Application - Conflicting URI templates

    - by user1231583
    I have a small Java Web Application in which I am using Jersey 1.12 and the Hadoop 1.0.0 JAR file (hadoop-core-1.0.0.jar). When I deploy my application to my JBoss 5.0 server, the log file records the following error: SEVERE: Conflicting URI templates. The URI template / for root resource class org.apache.hadoop.hdfs.server.namenode.web.resources.NamenodeWebHdfsMethods and the URI template / transform to the same regular expression (/.*)? To make sure my code is not the problem, I have created a fresh web application that contains nothing but the Jersey and Hadoop JAR files along with a small stub. My web.xml is as follows: <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet> <servlet-name>ServletAdaptor</servlet-name> <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet- class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>ServletAdaptor</servlet-name> <url-pattern>/mytest/*</url-pattern> </servlet-mapping> <session-config> <session-timeout> 30 </session-timeout> </session-config> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app> My simple RESTful stub is as follows: import javax.ws.rs.core.Context; import javax.ws.rs.core.UriInfo; import javax.ws.rs.Path; @Path("/mytest") public class MyRest { @Context private UriInfo context; public MyRest() { } } In my regular application, when I remove the Hadoop JAR files (and the code that is using Hadoop), everything works as I would expect. The deployment is successful and the remaining RESTful services work. I have also tried the Hadoop 1.0.1 JAR files and have had the same problems with the conflicting URL template in the NamenodeWebHdfsMethods class. Any suggestions or tips in solving this problem would be greatly appreciated.

  • flex strange problem with namespaces.

    - by pfunc
    I'm trying to understand what is going on with my namespaces since I upgraded to flash builder 4. xmlns:mx="http://www.adobe.com/2006/mxml" in the application and in the stylesheets: @namespace mx "library://ns.adobe.com/flex/mx"; Everything seems to be recognized correctly, however, I get a warning that says "borderThickness" is only supported by the halo theme (which I thought was in the mx theme). Now, when I try xmlns:s="library://ns.adobe.com/flex/mx" then it doesn;t recognize anything. Is there something I might be doing wrong here or confusing?

  • NullPointerException using datanucleus-json with S3

    - by Matt
    I'm using datanucleus 3.2.7 from Maven, trying to use the Amazon S3 JPA provider. I can successfully write data into S3, but querying either by using "SELECT u FROM User u" or "SELECT u FROM User u WHERE id = :id" causes a NullPointerException to be thrown. Using the RDBMS provider, everything works perfectly. Is there something I'm doing wrong?

  • Not able to pass multiple override parameters using nose-testconfig 0.6 plugin in nosetests

    - by Jaikit
    Hi, I am able to override multiple config parameters using nose-testconfig plugin only if i pass the overriding parameters on commandline. e.g. nosetests -c nose.cfg -s --tc=jack.env1:asl --tc=server2.env2:abc But when I define the same thing inside nose.cfg, than only the value for last parameter is modified. e.g. tc = server2.env2:abc tc = jack.env1:asl I checked the plugin code. It looks fine to me. I am pasting the part of plugin code below: parser.add_option( "--tc", action="append", dest="overrides", default = [], help="Option:Value specific overrides.") configure: if options.overrides: self.overrides = [] overrides = tolist(options.overrides) for override in overrides: keys, val = override.split(":") if options.exact: config[keys] = val else: ns = ''.join(['["%s"]' % i for i in keys.split(".") ]) # BUG: Breaks if the config value you're overriding is not # defined in the configuration file already. TBD exec('config%s = "%s"' % (ns, val)) Let me know if any one has any clue.

  • java System.nanoTime is really slow. Is it possible to implement a high performance java profiler?

    - by willpowerforever
    I did a test and found the overhead of a function call to System.nanoTime() is at least 500 ns on my machine. Seemed that it is very hard to have a high performance java profiler. For enterprise software, suppose a function takes about 350 seconds and has 12,500,000,000 times of method calls. Therefore, the number of calls to System.nanoTime() is: 12,500,000,000 * 2 = 25,000,000,000 (one for start timestamp, one for end timestamp) And the overhead of System.nanoTime in total is: 500 ns * 25,000,000,000 = 500 * 25000 s = 12500000s. Note: all data from real case. Any better way to acquire the timestamp?

  • Flex: convert VideoPlayer.currentTime to string "00:00:00:000"

    Hi there! what about this one: I want to format the currentTime displayed by a videoPlayer component inside flex, something like : 8230.999 to something like 01:59:59:999 which is "hours:minutes:seconds:milliseconds" I trie different sets of codes but they can't get it to work because currentTime is nor a correct miliseconds time as it adds a floating 3 digit point to seconds; so instead of : 2000ms it outputs 2.000 something people like me just can't understand! thanx for any help :) ### UPDATE I still have problem with milliseconds. here's the current MXML: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"> <fx:Script> <![CDATA[ protected function convert_clickHandler(event:MouseEvent):void { var val:Number = new Number(inPut.text); //inPut.text = 1000.001 //val = val * 1000; outPut.text = timeFormat(val); } public static function timeFormat(value:Number):String { var milliseconds:Number = value % 1000; var seconds:Number = Math.floor((value/1000) % 60); var minutes:Number = Math.floor((value/60000) % 60); var hours:Number = Math.floor((value/3600000) % 24); var s_miliseconds:String = (milliseconds<10 ?

  • What is the correct way to reference RDFa namespaces in HTML5?

    - by Eivind Eidheim Elseth
    I'm setting up a HTML5 webpage and want to include RDFa. I try checking the syntax with the w3 validator, and check the extracted RDF using the w3 RDFa distiller. When I declare namespaces using xmlns:<ns>="<uri>" the validator complains that the attribute is not allowed there, and the specs say that xmlns is deprecated, but if I try the other suggested prefix="<ns> <uri>" the distiller doesn't discover the RDFa embedded on my page. Which way should I stick to?
