• ASP.NET MVC - Find Absolute Path to the App_Data folder from Controller

  - by tyndall

  What is the correct way to find the absolute path to the App_Data folder from a Controller in an ASP.NET MVC project? I'd like to be able to temporarily work with an .xml file and I don't want to hardcode the path. This does not work: [HandleError] public class HomeController : Controller { public ActionResult Index() { string path = VirtualPathUtility.ToAbsolute("~/App_Data/somedata.xml"); //.... do whatever return View(); } } I think outside of the web context VirtualPathUtility.ToAbsolute() doesn't work. string path comes back as "C:\App_Data\somedata.xml" Where should I determine the path of the .xml file in an MVC app? global.asax and stick it an application-level variable?

• Writing a docx file to a BLOB using Java 1.4 inside Oracle 10g

  - by Jon Renaut

  I'm trying to generate a blank docx file using Java, add some text, then write it to a BLOB that I can return to our document processing engine (a custom mess of PL/SQL and Java). I have to use the 1.4 JVM inside Oracle 10g, so no Java 1.5 stuff. I don't have a problem writing the docx to a file on my local machine, but when I try to write to BLOB, I'm getting garbage. Am I doing something dumb? Any help is appreciated. Note in the code below, all the get[name]Xml() methods return an org.w3c.dom.Document. public void save(String fileName) throws Exception { ZipOutputStream zos = new ZipOutputStream(new FileOutputStream(fileName)); addEntry(zos, getDocumentXml(), "word/document.xml"); addEntry(zos, getContentTypesXml(), "[Content_Types].xml"); addEntry(zos, getRelsXml(), "_rels/.rels"); zos.flush(); zos.close(); } public java.sql.BLOB save() throws Exception { java.sql.Connection conn = DbUtilities.openConnection(); BLOB outBlob = BLOB.createTemporary(conn, true, BLOB.DURATION_SESSION); outBlob.open(BLOB.MODE_READWRITE); ZipOutputStream zos = new ZipOutputStream(outBlob.setBinaryStream(0L)); addEntry(zos, getDocumentXml(), "word/document.xml"); addEntry(zos, getContentTypesXml(), "[Content_Types].xml"); addEntry(zos, getRelsXml(), "_rels/.rels"); zos.flush(); zos.close(); return outBlob; } private void addEntry(ZipOutputStream zos, Document doc, String fileName) throws Exception { Transformer t = TransformerFactory.newInstance().newTransformer(); ByteArrayOutputStream baos = new ByteArrayOutputStream(); t.transform(new DOMSource(doc), new StreamResult(baos)); ZipEntry ze = new ZipEntry(fileName); byte[] data = baos.toByteArray(); ze.setSize(data.length); zos.putNextEntry(ze); zos.write(data); zos.flush(); zos.closeEntry(); }

• Use DataSource in DataFormWebPart

  - by Bryan Shen

  I'm writing a custom web part that extends DataFormWebPart. public class MyCustomWebPart : DataFormWebPart{ // other methods public override void DataBind() { XmlDataSource source = new XmlDataSource() { Data = @" <Person> <name cap='true'>Bryan</name> <occupation>student</occupation> </Person> " }; DataSources.Add(source); base.DataBind(); } } The only noticeable thing I do is overriding the DataBind() method, where I use xml as the data source. After I deploy the web part, I set the following XSL to it: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/> <xsl:template match="/"> <xmp> <xsl:copy-of select="*"/> </xmp> </xsl:template> </xsl:stylesheet> This xsl will surround the input xml with a tag . So I expected the web part to display the original xml data as I wrote in C# code behind. But what shows up in the web part is this: <Person> <name cap="true" /> <occupation /> </Person> All the values within the inner-most tags disappear. What's going on? Can anybody help me? Thanks.

• Preserving case in HTTP headers with Ruby's Net:HTTP

  - by emh

  Although the HTTP spec says that headers are case insensitive; Paypal, with their new adaptive payments API require their headers to be case-sensitive. Using the paypal adaptive payments extension for ActiveMerchant (http://github.com/lamp/paypal_adaptive_gateway) it seems that although the headers are set in all caps, they are sent in mixed case. Here is the code that sends the HTTP request: headers = { "X-PAYPAL-REQUEST-DATA-FORMAT" => "XML", "X-PAYPAL-RESPONSE-DATA-FORMAT" => "JSON", "X-PAYPAL-SECURITY-USERID" => @config[:login], "X-PAYPAL-SECURITY-PASSWORD" => @config[:password], "X-PAYPAL-SECURITY-SIGNATURE" => @config[:signature], "X-PAYPAL-APPLICATION-ID" => @config[:appid] } build_url action request = Net::HTTP::Post.new(@url.path) request.body = @xml headers.each_pair { |k,v| request[k] = v } request.content_type = 'text/xml' proxy = Net::HTTP::Proxy("127.0.0.1", "60723") server = proxy.new(@url.host, 443) server.use_ssl = true server.start { |http| http.request(request) }.body (i added the proxy line so i could see what was going on with Charles - http://www.charlesproxy.com/) When I look at the request headers in charles, this is what i see: X-Paypal-Application-Id ... X-Paypal-Security-Password... X-Paypal-Security-Signature ... X-Paypal-Security-Userid ... X-Paypal-Request-Data-Format XML X-Paypal-Response-Data-Format JSON Accept */* Content-Type text/xml Content-Length 522 Host svcs.sandbox.paypal.com I verified that it is not Charles doing the case conversion by running a similar request using curl. In that test the case was preserved.

• Wix XmlFile is keeping SqlDatabase from creating databases

  - by Grandpappy

  I've got a Wix project made up of several fragments. One of those fragments has the database components, another has a component that manipulates xml files. When I include the XmlFile element to manipulate a file, the databases defined by the SqlDatabase do not get created. If I comment out the XmlFile, then the databases do get created. Here are the two wix files with fragments that are being used: Database: <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:sql="http://schemas.microsoft.com/wix/SqlExtension"> <Fragment> <DirectoryRef Id="TARGETDIR"> <Component Id="Database1Creation" Guid="GUID_HERE"> <sql:SqlDatabase Id="Database1" Server="[DATABASE_SERVER]" Database="[DATABASE_NAME]" CreateOnInstall="yes" ConfirmOverwrite="no" DropOnUninstall="yes"> </sql:SqlDatabase> </Component> </DirectoryRef> </Fragment> </Wix> Xml Manipulation: <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi" xmlns:sql="http://schemas.microsoft.com/wix/SqlExtension" xmlns:util="http://schemas.microsoft.com/wix/UtilExtension"> <Fragment> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="ProgramFilesFolder"> <Directory Id="INSTALLDIR" Name="MyDirectory"> <Component Id="ServiceExecutables" Guid="GUID_HERE"> <File Id="File1" Name="File1.xml" Source="Source/File1.xml" /> <util:XmlFile Id="UpdateFile1" File="[INSTALLDIR]File1.xml" Action="setValue" ElementPath="//SomeContainer/SomeElement" Value="[SOME_VALUE]" /> </Component> </Directory> </Directory> </Directory> </Fragment> </Wix> There are other things that are also installed, but they don't appear to have any influence on the issue (I've removed everything else and tested the install). When looking at the install logs when using XmlFile and when not, they are almost exact copies of each other, except that the SqlDatabase calls would be completely missing, and the XmlFile calls would be in their place. Is there a known bug here? Or am I doing something I shouldn't be? This isn't a killer for our app, since I can move the things I'm putting in the xml file into the registry, but I'd rather not do that. I am using Wix 3.5.

  I get an empty response back from this local WebService call via jquery / ajax. I have verified the URL and XML input string by invoking the call in a browser. I DO get XML code back as expected.

• FullCalendar and events: function

  - by Ernest

  I am trying to display my events from a MySQL database. I'm using the events function. My XML file being returned is pretty basic. I've looked at all of the FullCalendar questions and most of them talk about JSON and point to the documentation for JSON. I can't use JSON. I have to go XML. Can you tell me where I'm off. Here is a sample of what my xml looks like: Grow Your Business on the Web 2010-06-05T9:30 2010-06-05T12:30 O The whole file is prefaced with a tag and closed with a tag. My jquery is as follows: $(document).ready(function() { $('#calendar').fullCalendar({ height: 550, theme: true, header: { left: 'prev,next today', center: 'title', right: 'month,agendaWeek,agendaDay' }, editable: true, events: function(start, end, callback) { $.ajax({ url: 'ncludeFiles/sbdp-cal-xml.php', dataType: 'xml', data: { // our hypothetical feed requires UNIX timestamps start: Math.round(start.getTime() / 1000), end: Math.round(end.getTime() / 1000) }, success: function(doc) { var events = []; $(doc).find('event').each(function() { events.push({ title: $(this).attr('title'), start: $(this).attr('start'), end: $(this).attr('end'), className: $(this).attr('className'), url: $(this).attr('url') }); }); callback(events); } }); } }); }); I'd appreciate any help you could give me. Thanks!

• Improving long-polling Ajax performance

  - by Bears will eat you

  I'm writing a webapp (Firefox-compatible only) which uses long polling (via jQuery's ajax abilities) to send more-or-less constant updates from the server to the client. I'm concerned about the effects of leaving this running for long periods of time, say, all day or overnight. The basic code skeleton is this: function processResults(xml) { // do stuff with the xml from the server } function fetch() { setTimeout(function () { $.ajax({ type: 'GET', url: 'foo/bar/baz', dataType: 'xml', success: function (xml) { processResults(xml); fetch(); }, error: function (xhr, type, exception) { if (xhr.status === 0) { console.log('XMLHttpRequest cancelled'); } else { console.debug(xhr); fetch(); } } }); }, 500); } (The half-second "sleep" is so that the client doesn't hammer the server if the updates are coming back to the client quickly - which they usually are.) After leaving this running overnight, it tends to make Firefox crawl. I'd been thinking that this could be partially caused by a large stack depth since I've basically written an infinitely recursive function. However, if I use Firebug and throw a breakpoint into fetch, it looks like this is not the case. The stack that Firebug shows me is only about 4 or 5 frames deep, even after an hour. One of the solutions I'm considering is changing my recursive function to an iterative one, but I can't figure out how I would insert the delay in between Ajax requests without spinning. I've looked at the JS 1.7 "yield" keyword but I can't quite wrap my head around it, to figure out if it's what I need here. Is the best solution just to do a hard refresh on the page periodically, say, once every hour? Is there a better/leaner long-polling design pattern that won't put a hurt on the browser even after running for 8 or 12 hours? Or should I just skip the long polling altogether and use a different "constant update" pattern since I usually know how frequently the server will have a response for me?

• Android: SharedPreference: Defaults not set at startup...

  - by Allan

  I have Listpreferences in my app. They don't appear to be setting to their defaults right after installation - they appear to be null. I'm trying to figure out why my default preferences are not being set right after installation. In my main code I have: SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this); InUnits = sp.getString("List1", "defValue"); InAngs = sp.getString("List2", "defValue"); OutUnits = sp.getString("List3", "defValue"); OutAngs = sp.getString("List4", "defValue"); Right after the above code executes, each variable contains "defValue" instead of the actual values I have assigned in my ListPreference below. My preference xml file is called, "settings.xml". Here's what one of the ListPreferences there looks like: <ListPreference android:key="List1" android:title="Input: Alph" android:summary="Choose Alph or Ralph" android:entries="@array/inputAlph" android:entryValues="@array/input_Alph_codes" android:dialogTitle="Input Alph" android:defaultValue="ININ"/> Here's what some of my strings.xml file looks like: <string-array name="inputUnits"> <item>Alph</item> <item>Ralph</item> </string-array> <string-array name="input_Alph_codes"> <item>ININ</item> <item>INMM</item> </string-array> When I go to menu, and then settings, I can see my defaults checked (radiobuttoned). Then when I go back from the settings menu to my main screen - all is well - for life! ...then each var above is assigned the proper default value. This only happens when I first install my app on the phone. After I go to the settings screen once and then right out of it, the app is fine and accepts any setting changes. By the way, as you can see, "List1" is the android:key within a file called settings.xml in my res/xml folder.

• On REST: WADL or not IDL, is the following approach right ?

  - by redben

  This question is a bit long, please bear with me. In REST, i think we should not need WADL or any IDL. But rather something that would implicitly cover its concept. The way I think about it is when we (humans) surf the Web, when we go to a web site for the first time, we don't know what services it provides. You discover those on the html home page (or a sitemap page in a help section) or maybe just the main menu on the home page. If you make an analogy, the homepage or site map to us humans is what WSDL is to WS-* or what WADL could be to a REST service. Only that its just like any other html content. I think that in REST the following is a good way to do things, respecting the HATEOS paradigm. Have a top level (or default) resource that lists links to your other resources. For a library example, say RestLibrary.com/ it could be something like: <root xmlns:lib="http://librarystandards.com/libraryml"> <resource class="lib:book"> <link type="application/vnd.libraryml+xml" template="mylib.com/book/{isbn}" /> <link type="application/vnd.libraryml+xml" rel="add" href="mylib.com/book" method="POST" /> <link type="application/vnd.libraryml+xml" rel="update" template="mylib.com/book/{isbn}" method="PUT" /> </resource> <resource class="lib:bookList"> <link template="mylib.com/book?keywords={keywords}" type="application/vnd.openlibrary+xml" rel="search" /> </resource> </root> Note that it is assumed that the media type "application/vnd.libraryml+xml" is a defined standard or (may be just proprietary vocabulary) named libraryml. Also, the client should be able to understand this "homepage" resource (elements root, resource and link). This is the part that could be used instead of WADL : an Abstract vocabulary that should be understandable by any client. You could use an existing standard like Atom for example. But the main idea is to have an abstract vocabulary understandable by any client. Why not WADL then ? well wadl is only for service discovery. The idea here is to have an light abstract vocabulary that would serve as a base for hypermedia. A "root" vocabulary. Like in owl we have owl:thing...etc Now if the client knows the "libraryml" standard it can follow the links to the things it understands (after parsing the media type properties and xmlns). If not, it just won't. When i can't understand how to deal with something in REST architecture i tend to see how we Humans do it in the Web. In the Web, we have the Generic language that is HTML that enables site builders to deliver any specific content, regardless of its meaning to the client (the user), Browsers understand HTML but not the "meaning" of its content. It is the user that understands the (domain specific) content. If i go to say QuantumPhysics.org, my browser can render the home page (it is just html after all) and i can read the home page. If i understand quantum then fine i can continue browsing. If i don't i just get out (unless i want to learn the hardway :) ) In the RetsLibrary.com example the client app is just like me+my browser on QuantumPhysics.org. the media type "application/vnd.libraryml+xml" is quantum physics (knowledge). http is http in both examples. Now HTML of QuantumPhysics.org is in RestLibrary.com is XML + that tiny little abstract vocabulary (root resource and link, that you could replace with something like Atom). So does this approach have any value ? don't we need a root tiny hyper-vocabulary so we can succeed with hypermedia and the "initial URI" concept ? edit Yeah why not RDF as the root vocabulary !

• Ruby on Rails: having two xmlbuilder templates per action , one for errors one for regular output

  What's the best way to handle having two templates (or should it be one, DRY?) for xml builder templates? I'm building a web api with Rails and wanted to see an example of how to have a view that does regular output vs one that does error output. I've been using @obj.to_xml for a while, but my requirements have changed and require me building my own error templates. do you typically have both views in one with a condition above for errors such as app/views/myresource/create.xml.builder unless @myobj.errors.empty? // xml for errors here? end // regular xml view

In the XML file I do not see theh xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" attribute with the root tag. My xsd Below is the code : public class JAXBConstructor { public void generateXMLDocument(File xmlDocument){ try { JAXBContext jaxbContext = JAXBContext.newInstance("com"); Marshaller marshaller = jaxbContext.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); com.ObjectFactory factory = new com.ObjectFactory(); USERTASKSImpl userTasks =(USERTASKSImpl)(factory.createUSERTASKS()); USERTASKTypeImpl userTaskType = (USERTASKTypeImpl)(factory.createUSERTASKSTypeUSERTASKType()); userTaskType.setName("zmannan"); userTaskType.setCode("G5023920"); java.util.List userTaskList=userTasks.getUSERTASK(); userTaskList.add(userTaskType); marshaller.marshal(userTasks, new FileOutputStream("User_Task.xml")); } Output of the code : This does not contain the XMLSchema value - < ?xml version="1.0" encoding="UTF-8" standalone="yes"? < USER_TASKS xmlns="http://schemas.jpmchase.net/Recertification" < CodeG5023920< /Code < Namezmannan< /Name < /USER_TASK < /USER_TASKS Please help how can I add the schema-instance value in the rrot tag.

• Android: Make application background behave like homescreen background

  - by Mannaz

  Hi, I have a big background image for my views's background, which also can be tiled (it's repeadable). When switching from one Activity to another i want the background to behave like on the homescreen (the background moves only a bit, but the foreground moves one screen with). Is this possible and how? Here is my current background definition: Manifest.xml: <application android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@style/MyAppStyle"> styles.xml: <style name="MyAppStyle" parent="@android:style/Theme.NoTitleBar"> <item name="android:windowBackground">@drawable/window_background_descriptor</item> window_background_descriptor.xml: <?xml version="1.0" encoding="utf-8"?> <bitmap xmlns:android="http://schemas.android.com/apk/res/android" android:src="@drawable/window_background" android:tileMode="repeat" />

• How to configure properly IntelliJ IDEA for deployment of JBoss Seam project?

  - by Piotr Kochanski

  I would like to use IntelliJ IDEA for development of JBoss Seam project. seam-gen is creating the project stub, however the stub is not complete. In particular it is not clear how to deploy such project. First of all I had to define manually web project facelet and add libraries to its deployment definition. The other problem was persistence.xml file. In the Seam generated project it does not exists, since Ant is using one of the persistence-dev.xml, persistence-prod.xml, persistence-test.xml files, changing its name, depending on deployment type (which is ok). Obviously I can create persistence.xml by hand, but it goes againts Seam way of development. Finally I decided to use directly ant, which is not partucularly comfortable. All these tweaks made me think that I am doing something wrong from the IntelliJ IDEA point of view. What is the efficient way of configuring IntelliJ for usage with JBoss Seam (deployment, in particular)? I am using JBoss Seam 2.1.1, Intellij 8.1.4, JBoss 4.3.3

• How can I validate the output of XmlSerializer?

  - by Tim Jansen

  In C# / .NET 2.0, when I serialize an object using XmlSerializer, what's the easiest way to validate the output against an XML schema? The problem is that it is all too easy to write invalid XML with the XmlSerializer, and I can't find a way to validate the XML that does not look cumbersome. Ideally I would expect to set the schema in the XmlSerializer or to have a XmlWriter that validates.

• Problem: adding feature in MOSS 2007

  - by Anoop

  Hi All, I have added a menu item in 'Actions' menu of a document library as follows(Using features: explained in MSDN How to: Add Actions to the User Interface: http://msdn.microsoft.com/en-us/library/ms473643.aspx): feature.xml as follows: <?xml version="1.0" encoding="utf-8" ?> <Feature Id="51DEF381-F853-4991-B8DC-EBFB485BACDA" Title="Import From REP" Description="This example shows how you can customize various areas inside Windows SharePoint Services." Version="1.0.0.0" Scope="Site" xmlns="http://schemas.microsoft.com/sharepoint/"> <ElementManifests> <ElementManifest Location="ImportFromREP.xml" /> </ElementManifests> </Feature> ImportFromREP.xml is as follows: <?xml version="1.0" encoding="utf-8"?> <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> <!-- Document Library Toolbar Actions Menu Dropdown --> <CustomAction Id="ImportFromREP" RegistrationType="List" RegistrationId = "101" GroupId="ActionsMenu" Rights="AddListItems" Location="Microsoft.SharePoint.StandardMenu" Sequence="1000" Title="Import From REP"> <UrlAction Url="/_layouts/ImportFromREP.aspx?ActionsMenu"/> </CustomAction> </Elements> I have successfully installed and activated the feature. Normal case: Now if i login with the user having atleast 'Contribute' permission on the document library, i am able to see the menu item 'Import From REP' (in 'Actions' menu)in root folder as well as in all subfolders. Problem case: If user is having view rights on the document library but add/delete rights on a perticular subfolder(say 'subfolder') inside the document library: Menu item 'Import From REP' is not visible on root folder level as well as 'Upload' menu is also not visible. which is o.k. because user does not have AddListItems right on root folder but it is also not visible in 'subfolder' while 'Upload' menu is visible as user has add/delete rights on the 'subfolder'. did i mention a wrong value of attribute Rights(Rights="AddListItems") in the xml file?? If so, what should be the correct value? What should i do to simulate the behaviour of 'Upload' menu??(i.e. when 'Upload' menu is visible, 'Import From REP' menu is visible and when 'Upload' menu is not visible 'Import From REP' menu is also not visible. ) Thanks in advance Anoop
