• Jboss Seam: Enabling Debug page on WebLogic 10.3.2 (11g)

  - by Markos Fragkakis

  Hi all, SKIP TO UPDATE 3 I want to enable the Seam debug page on Weblogic 10.3.2 (11g). So, I have done the following: I have the jboss-seam and jboss-seam-debug jars as dependency in both my ejb and web maven projects (both are modules of my superproject) I put this context parameter in my web.xml: <context-param> <param-name>org.jboss.seam.core.init.debug</param-name> <param-value>true</param-value> </context-param> Now, when I hit the URL of my application, I get the debug page with this exception (full stacktrace at the end of the post): Caused by java.lang.IllegalStateException with message: "No phase id bound to current thread (make sure you do not have two SeamPhaseListener instances installed)" From posts I read it seems that this is somehow related to two jars of jboss-seam or jboss-seam-debug being in the classpath. I opened my ear file and only one of each is present (in the ear) whereas the war itself has no libraries in the WEB-INF/lib. I have also read of another way to initialize debug page using the components.xml. I also tried to include the following components.xml in the WEB-INF, but it didn't work either: <?xml version="1.0" encoding="UTF-8"?> <components xmlns="http://jboss.com/products/seam/components" xmlns:core="http://jboss.com/products/seam/core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://jboss.com/products/seam/core http://jboss.com/products/seam/core-2.2.xsd http://jboss.com/products/seam/components http://jboss.com/products/seam/components-2.2.xsd"> <core:init debug="true"/> </components> Any suggestions on what to do to enable the debug page correctly? Cheers!

They have an outer EAR project containing the inner WAR project. They discuss that this may be related to how jars end up in the projects. I use Maven, and I had set it to create "Skinny Wars", that is excluding all jar dependencies from the inner WAR project, so that it remains small in size. All its dependencies are contained in the EAR and are used by all other modules. I changed the settings of the maven-war-plugin to leave inside the war the web-specific jars (the ones mentioned in the link, like RichFaces, jboss-seam-debug, Facelets etc). However, the problem has reverted to its previous form. I now get the debug page, whatever link I press, with the initial exception. Caused by java.lang.IllegalStateException with message: "No phase id bound to current thread (make sure you do not have two SeamPhaseListener instances installed)" UPDATE 3: The structure of the application .ear is the following: application.ear |--> APP-INF | |--> classes |--> lib (all jar dependencies go here, including the WAR dependencies, EJB module dependencies) |-->META_INF | |--> application.xml | |--> data-sources.xml | |--> MANIFEST.MF | |--> weblogic.xml | |--> weblogic-application.xml |--> jboss-seam-2.2.0.GA.jar |--> myEjbModule1.jar |--> myEjbModule2.jar |--> myEjbModule3.jar |--> myEjbModule4.jar |--> myWar.war (NO libraries in WEB-INF/lib, finds everything in EAR/lib) When deploying .ear application WITHOUT debug enabled (not including the jboss-seam-debug.jar in the ear), the application is loaded correctly. When deploying WITH jboss-seam-debug.jar in the EAR (EAR/lib directory), the application does not appear, but ONLY the debug page with the following exception (stacktrace at the end): Exception during request processing: Caused by java.lang.IllegalStateException with message: "No phase id bound to current thread (make sure you do not have two SeamPhaseListener instances installed)" When "JBoss-izing" the same EAR (remove hibernate jars, which are provided by JBoss, and move all libraries from EAR/lib to EAR root), the application loads correctly. BOTH the application AND the debug page appear correctly.

  Following the spring-security documentation: http://static.springsource.org/spring-security/site/docs/3.0.x/reference/ldap.html I am trying to set up ldap authentication (very simple - just need to know if a user is authenticated or not, no authorities mapping needed) and have put this in my applicationContext-security.xml file <beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd"> ... <ldap-server url="ldap://adapps.company.com:389/dc=company,dc=com" /> <ldap-authentication-provider user-search-filter="(samaccountname={0})" user-search-base="dc=company,dc=com"/> The problem I run into is that it doesnt seem like ldap-authentication-provider; I fell like i may be missing some configuration isn the beans definition.

• How can I best share Ant targets between projects?

  - by Rob Hruska

  Is there a well-established way to share Ant targets between projects? I have a solution currently, but it's a bit inelegant. Here's what I'm doing so far. I've got a file called ivy-tasks.xml hosted on a server on our network. This file contains, among other targets, boilerplate tasks for managing project dependencies with Ivy. For example: <project name="ant-ivy-tasks" default="init-ivy" xmlns:ivy="antlib:org.apache.ivy.ant"> ... <target name="ivy-download" unless="skip.ivy.download"> <mkdir dir="${ivy.jar.dir}"/> <echo message="Installing ivy..."/> <get src="http://repo1.maven.org/maven2/org/apache/ivy/ivy/${ivy.install.version}/ivy-${ivy.install.version}.jar" dest="${ivy.jar.file}" usetimestamp="true"/> </target> <target name="ivy-init" depends="ivy-download" description="-> Defines ivy tasks and loads global settings"> <path id="ivy.lib.path"> <fileset dir="${ivy.jar.dir}" includes="*.jar"/> </path> <taskdef resource="org/apache/ivy/ant/antlib.xml" uri="antlib:org.apache.ivy.ant" classpathref="ivy.lib.path"/> <ivy:settings url="http://myserver/ivy/settings/ivysettings-user.xml"/> </target> ... </project> The reason this file is hosted is because I don't want to: Check the file into every project that needs it - this will result in duplication, making maintaining the targets harder. Have my build.xml depend on checking out a project from source control - this will make the build have more XML at the top-level just to access the file. What I do with this file in my projects' build.xmls is along the lines of: <property name="download.dir" location="download"/> <mkdir dir="${download.dir}"/> <echo message="Downloading import files to ${download.dir}"/> <get src="http://myserver/ivy/ivy-tasks.xml" dest="${download.dir}/ivy-tasks.xml" usetimestamp="true"/> <import file="${download.dir}/ivy-tasks.xml"/> The "dirty" part about this is that I have to do the above steps outside of a target, because the import task must be at the top-level. Plus, I still have to include this XML in all of the build.xml files that need it (i.e. there's still some amount of duplication). On top of that, there might be additional situations where I might have common (non-Ivy) tasks that I'd like imported. If I were to provide these tasks using Ivy's dependency management I'd still have problems, since by the time I'd have resolved the dependencies I would have to be inside of a target in my build.xml, and unable to import (due to the constraint mentioned above). Is there a better solution for what I'm trying to accomplish?

• how do I access XHR responseBody from Javascript?

  - by Cheeso

  I've got a web page that uses XMLHttpRequest to download a binary resource. Because it's binary I'm trying to use xhr.responseBody to access the bytes. I've seen a few posts suggesting that it's impossible to access the bytes directly from Javascript. This sounds crazy to me. Weirdly, xhr.responseBody is accessible from VBScript, so the suggestion is that I must define a method in VBScript in the webpage, and then call that method from Javascript. See jsdap for one example. var IE_HACK = (/msie/i.test(navigator.userAgent) && !/opera/i.test(navigator.userAgent)); if (IE_HACK) document.write('<script type="text/vbscript">\n\ Function BinaryToArray(Binary)\n\ Dim i\n\ ReDim byteArray(LenB(Binary))\n\ For i = 1 To LenB(Binary)\n\ byteArray(i-1) = AscB(MidB(Binary, i, 1))\n\ Next\n\ BinaryToArray = byteArray\n\ End Function\n\ </script>'); var xml = (window.XMLHttpRequest) ? new XMLHttpRequest() // Mozilla/Safari/IE7+ : (window.ActiveXObject) ? new ActiveXObject("MSXML2.XMLHTTP") // IE6 : null; // Commodore 64? xml.open("GET", url, true); if (xml.overrideMimeType) { xml.overrideMimeType('text/plain; charset=x-user-defined'); } else { xml.setRequestHeader('Accept-Charset', 'x-user-defined'); } xml.onreadystatechange = function() { if (xml.readyState == 4) { if (!binary) { callback(xml.responseText); } else if (IE_HACK) { // call a VBScript method to copy every single byte callback(BinaryToArray(xml.responseBody).toArray()); } else { callback(getBuffer(xml.responseText)); } } }; xml.send(''); Is this really true? The best way? copying every byte? For a large binary stream that's not gonna be very efficient. There is also a possible technique using ADODB.Stream, which is a COM equivalent of a MemoryStream. See here for an example. It does not require VBScript but does require a separate COM object. if (typeof (ActiveXObject) != "undefined" && typeof (httpRequest.responseBody) != "undefined") { // Convert httpRequest.responseBody byte stream to shift_jis encoded string var stream = new ActiveXObject("ADODB.Stream"); stream.Type = 1; // adTypeBinary stream.Open (); stream.Write (httpRequest.responseBody); stream.Position = 0; stream.Type = 1; // adTypeBinary; stream.Read.... /// ???? what here } I don't think that's gonna work - ADODB.Stream is disabled on most machines these days. In The IE8 developer tools - the IE equivalent of Firebug - I can see the responseBody is an array of bytes and I can even see the bytes themselves. The data is right there. I don't understand why I can't get to it. Is it possible for me to read it with responseText? hints? (other than defining a VBScript method)

• rails: "unknown action" message when action is clearly specified

  - by john

  hi, I had hard time to figure out why I've been getting "unknown action" error message when I was do some editing: Unknown action No action responded to 11. Actions: bin, create, destroy, edit, index, new, observe_new, show, tag, update, and vote you can see that Rails did mention each action in the above list - update. And in my form, I did specify action = "update". I wonder if some friends could kindly help me with the missing links... here is the code: edit.rhtml <h1>Editing tip</h1> <% form_tag :action => 'update', :id => @tip do %> <%= render :partial => 'form' %> <p> <%= submit_tag_or_cancel 'Save Changes' %> </p> <% end %> _form.rhtml <%= error_messages_for :tip %> <p><label>Title<br/> <%= text_field :tip, :title %></label></p> <p><label>Categories<br/> <%= select_tag('categories[]', options_for_select(Category.find(:all).collect {|c| [c.name, c.id] }, @tip.category_ids), :multiple => true ) %></label></p> <p><label>Abstract:<br/> <%= text_field_with_auto_complete :tip, :abstract %></label></p> <p><label>Name: <br/> <%= text_field :tip, :name %></label></p> <p><label>Link: <br/> <%= text_field :tip, :link %></label></p> <p><label>Content<br/> <%= text_area :tip, :content, :rows => 5 %></label></p> <p><label>Tags <span>(space separated)</span><br/> <%= text_field_tag 'tags', @tip.tag_list, :size => 40 %></label></p> class TipsController < ApplicationController before_filter :authenticate, :except => %w(index show) # GET /tips # GET /tips.xml def index @tips = Tip.all respond_to do |format| format.html # index.html.erb format.xml { render :xml => @tips } end end # GET /tips/1 # GET /tips/1.xml def show @tip = Tip.find_by_permalink(params[:permalink]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @tip } end end # GET /tips/new # GET /tips/new.xml def new @tip = session[:tip_draft] || current_user.tips.build end def create #tip = current_user.tips.build(params[:tip]) #tipMail=params[:email] #if tipMail # TipMailer.deliver_email_friend(params[:email], params[:name], tip) # flash[:notice] = 'Your friend has been notified about this tip' #end @tip = current_user.tips.build(params[:tip]) @tip.categories << Category.find(params[:categories]) unless params[:categories].blank? @tip.tag_with(params[:tags]) if params[:tags] if @tip.save flash[:notice] = 'Tip was successfully created.' session[:tip_draft] = nil redirect_to :action => 'index' else render :action => 'new' end end def edit @tip = Tip.find(params[:id]) end def update @tip = Tip.find(params[:id]) respond_to do |format| if @tip.update_attributes(params[:tip]) flash[:notice] = 'Tip was successfully updated.' format.html { redirect_to(@tip) } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @tip.errors, :status => :unprocessable_entity } end end end def destroy @tip = Tip.find(params[:id]) @tip.destroy respond_to do |format| format.html { redirect_to(tips_url) } format.xml { head :ok } end end def observe_new session[:tip_draft] = current_user.tips.build(params[:tip]) render :nothing => true end end

• xsl:include template with no default namespace causes xmlns=""

  - by CraftyFella

  Hi, I've got a problem with xsl:include and default namespaces which is causing the final xml document contain nodes with the xmlns="" In this synario I have 1 source document which is Plain Old XML and doesn't have a namespace: <?xml version="1.0" encoding="UTF-8"?> <SourceDoc> <Description>Hello I'm the source description</Description> <Description>Hello I'm the source description 2</Description> <Description/> <Title>Hello I'm the title</Title> </SourceDoc> This document is transformed into 2 different xml documents each with their own default namespace. First Document: <?xml version="1.0" encoding="utf-8"?> <OutputDocType1 xmlns="http://MadeupNS1"> <Description >Hello I'm the source description</Description> <Description>Hello I'm the source description 2</Description> <Title>Hello I'm the title</Title> </OutputDocType1> Second Document: <?xml version="1.0" encoding="utf-8"?> <OutputDocType2 xmlns="http://MadeupNS2"> <Description>Hello I'm the source description</Description> <Description>Hello I'm the source description 2</Description> <DocTitle>Hello I'm the title</DocTitle> </OutputDocType2> I want to be able to re-use the template for descriptions in both of the transforms. As it's the same logic for both types of document. To do this I created a template file which was *xsl:include*d in the other 2 transformations: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output indent="yes" method="xml"/> <xsl:template match="Description[. != '']"> <Description> <xsl:value-of select="."/> </Description> </xsl:template> </xsl:stylesheet> Now the problem here is that this shared transformation can't have a default Namespace as it will be different depending on which of the calling transformations calls it. E.g. for First Document Transformation: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output indent="yes" method="xml"/> <xsl:template match="SourceDoc"> <OutputDocType1 xmlns="http://MadeupNS1"> <xsl:apply-templates select="Description"/> <xsl:if test="Title"> <Title> <xsl:value-of select="Title"/> </Title> </xsl:if> </OutputDocType1> </xsl:template> <xsl:include href="Template.xsl"/> </xsl:stylesheet> This actually outputs it as follows: <?xml version="1.0" encoding="utf-8"?> <OutputDocType1 xmlns="http://MadeupNS1"> <Description xmlns="">Hello I'm the source description</Description> <Description xmlns="">Hello I'm the source description 2</Description> <Title>Hello I'm the title</Title> </OutputDocType1> Here is the problem. On the description Lines I get an xmlns="" Does anyone know how to solve this issue? Thanks Dave

• Create and Share a File (Also a mysterious error)

  - by Kirk

  My goal is to create a XML file and then send it through the share Intent. I'm able to create a XML file using this code FileOutputStream outputStream = context.openFileOutput(fileName, Context.MODE_WORLD_READABLE); PrintStream printStream = new PrintStream(outputStream); String xml = this.writeXml(); // get XML here printStream.println(xml); printStream.close(); I'm stuck trying to retrieve a Uri to the output file in order to share it. I first tried to access the file by converting the file to a Uri File outFile = context.getFileStreamPath(fileName); return Uri.fromFile(outFile); This returns file:///data/data/com.my.package/files/myfile.xml but I cannot appear to attach this to an email, upload, etc. If I manually check the file length, it's proper and shows there is a reasonable file size. Next I created a content provider and tried to reference the file and it isn't a valid handle to the file. The ContentProvider doesn't ever seem to be called a any point. Uri uri = Uri.parse("content://" + CachedFileProvider.AUTHORITY + "/" + fileName); return uri; This returns content://com.my.package.provider/myfile.xml but I check the file and it's zero length. How do I access files properly? Do I need to create the file with the content provider? If so, how? Update Here is the code I'm using to share. If I select Gmail, it does show as an attachment but when I send it gives an error Couldn't show attachment and the email that arrives has no attachment. public void onClick(View view) { Log.d(TAG, "onClick " + view.getId()); switch (view.getId()) { case R.id.share_cancel: setResult(RESULT_CANCELED, getIntent()); finish(); break; case R.id.share_share: MyXml xml = new MyXml(); Uri uri; try { uri = xml.writeXmlToFile(getApplicationContext(), "myfile.xml"); //uri is "file:///data/data/com.my.package/files/myfile.xml" Log.d(TAG, "Share URI: " + uri.toString() + " path: " + uri.getPath()); File f = new File(uri.getPath()); Log.d(TAG, "File length: " + f.length()); // shows a valid file size Intent shareIntent = new Intent(); shareIntent.setAction(Intent.ACTION_SEND); shareIntent.putExtra(Intent.EXTRA_STREAM, uri); shareIntent.setType("text/plain"); startActivity(Intent.createChooser(shareIntent, "Share")); } catch (FileNotFoundException e) { e.printStackTrace(); } break; } } I noticed that there is an Exception thrown here from inside createChooser(...), but I can't figure out why it's thrown. E/ActivityThread(572): Activity com.android.internal.app.ChooserActivity has leaked IntentReceiver com.android.internal.app.ResolverActivity$1@4148d658 that was originally registered here. Are you missing a call to unregisterReceiver()? I've researched this error and can't find anything obvious. Both of these links suggest that I need to unregister a receiver. Chooser Activity Leak - Android Why does Intent.createChooser() need a BroadcastReceiver and how to implement? I have a receiver setup, but it's for an AlarmManager that is set elsewhere and doesn't require the app to register / unregister. Code for openFile(...) In case it's needed, here is the content provider I've created. public ParcelFileDescriptor openFile(Uri uri, String mode) throws FileNotFoundException { String fileLocation = getContext().getCacheDir() + "/" + uri.getLastPathSegment(); ParcelFileDescriptor pfd = ParcelFileDescriptor.open(new File(fileLocation), ParcelFileDescriptor.MODE_READ_ONLY); return pfd; }

• Bogus InvalidOperationException (in a DataServiceRequestException)

  - by Andrei Rinea

  I am having a hard time with ADO.NET Data Services (formerly code-named Astoria) as it gives me a bogus exception when I try to insert a new entity from the silverlight client and trying in a clean project (the same code) doesn't. In both cases, however, data is correctly inserted into the database. Using Fiddler (an HTTP debugger I could see that there is no problem in the HTTP communication as I will show later in this question. The code : var ctx = new MyProject123Entities(new Uri("http://andreiri/MyProject.Data/Data.svc")); var i = new Zone() { Data = DateTime.Now, IdElement = 1 }; ctx.AddToZone(i); i.StareZone = new StareZone() { IdStareZone = 1 }; ctx.AttachTo("StareZone", i.StareZone); ctx.SetLink(i, "StareZone", i.StareZone); i.TipZone = new TipZone() { IdTipZone = 1 }; ctx.AttachTo("TipZone", i.TipZone); ctx.SetLink(i, "TipZone", i.TipZone); i.User = new User() { IdUser = 2 }; ctx.AttachTo("User", i.User); ctx.SetLink(i, "User", i.User); ctx.BeginSaveChanges(r =] ctx.EndSaveChanges(r), null); when run the last line (ctx.EndSaveChanges(r)) will throw the following exception : System.Data.Services.Client.DataServiceRequestException was unhandled by user code Message="An error occurred while processing this request."

• How to open new view (call an activity) from options menu defined in XML? (android)

  - by Portablejim

  I cant seem to open a new view from an options menu item. The program keeps crashing as it applies the intent and listener to the item. I am just beginning, so please be nice.

• Node.js Adventure - Host Node.js on Windows Azure Worker Role

  - by Shaun

  In my previous post I demonstrated about how to develop and deploy a Node.js application on Windows Azure Web Site (a.k.a. WAWS). WAWS is a new feature in Windows Azure platform. Since it’s low-cost, and it provides IIS and IISNode components so that we can host our Node.js application though Git, FTP and WebMatrix without any configuration and component installation. But sometimes we need to use the Windows Azure Cloud Service (a.k.a. WACS) and host our Node.js on worker role. Below are some benefits of using worker role. - WAWS leverages IIS and IISNode to host Node.js application, which runs in x86 WOW mode. It reduces the performance comparing with x64 in some cases. - WACS worker role does not need IIS, hence there’s no restriction of IIS, such as 8000 concurrent requests limitation. - WACS provides more flexibility and controls to the developers. For example, we can RDP to the virtual machines of our worker role instances. - WACS provides the service configuration features which can be changed when the role is running. - WACS provides more scaling capability than WAWS. In WAWS we can have at most 3 reserved instances per web site while in WACS we can have up to 20 instances in a subscription. - Since when using WACS worker role we starts the node by ourselves in a process, we can control the input, output and error stream. We can also control the version of Node.js.   Run Node.js in Worker Role Node.js can be started by just having its execution file. This means in Windows Azure, we can have a worker role with the “node.exe” and the Node.js source files, then start it in Run method of the worker role entry class. Let’s create a new windows azure project in Visual Studio and add a new worker role. Since we need our worker role execute the “node.exe” with our application code we need to add the “node.exe” into our project. Right click on the worker role project and add an existing item. By default the Node.js will be installed in the “Program Files\nodejs” folder so we can navigate there and add the “node.exe”. Then we need to create the entry code of Node.js. In WAWS the entry file must be named “server.js”, which is because it’s hosted by IIS and IISNode and IISNode only accept “server.js”. But here as we control everything we can choose any files as the entry code. For example, I created a new JavaScript file named “index.js” in project root. Since we created a C# Windows Azure project we cannot create a JavaScript file from the context menu “Add new item”. We have to create a text file, and then rename it to JavaScript extension. After we added these two files we should set their “Copy to Output Directory” property to “Copy Always”, or “Copy if Newer”. Otherwise they will not be involved in the package when deployed. Let’s paste a very simple Node.js code in the “index.js” as below. As you can see I created a web server listening at port 12345. 1: var http = require("http"); 2: var port = 12345; 3:  4: http.createServer(function (req, res) { 5: res.writeHead(200, { "Content-Type": "text/plain" }); 6: res.end("Hello World\n"); 7: }).listen(port); 8:  9: console.log("Server running at port %d", port); Then we need to start “node.exe” with this file when our worker role was started. This can be done in its Run method. I found the Node.js and entry JavaScript file name, and then create a new process to run it. Our worker role will wait for the process to be exited. If everything is OK once our web server was opened the process will be there listening for incoming requests, and should not be terminated. The code in worker role would be like this. 1: public override void Run() 2: { 3: // This is a sample worker implementation. Replace with your logic. 4: Trace.WriteLine("NodejsHost entry point called", "Information"); 5:  6: // retrieve the node.exe and entry node.js source code file name. 7: var node = Environment.ExpandEnvironmentVariables(@"%RoleRoot%\approot\node.exe"); 8: var js = "index.js"; 9:  10: // prepare the process starting of node.exe 11: var info = new ProcessStartInfo(node, js) 12: { 13: CreateNoWindow = false, 14: ErrorDialog = true, 15: WindowStyle = ProcessWindowStyle.Normal, 16: UseShellExecute = false, 17: WorkingDirectory = Environment.ExpandEnvironmentVariables(@"%RoleRoot%\approot") 18: }; 19: Trace.WriteLine(string.Format("{0} {1}", node, js), "Information"); 20:  21: // start the node.exe with entry code and wait for exit 22: var process = Process.Start(info); 23: process.WaitForExit(); 24: } Then we can run it locally. In the computer emulator UI the worker role started and it executed the Node.js, then Node.js windows appeared. Open the browser to verify the website hosted by our worker role. Next let’s deploy it to azure. But we need some additional steps. First, we need to create an input endpoint. By default there’s no endpoint defined in a worker role. So we will open the role property window in Visual Studio, create a new input TCP endpoint to the port we want our website to use. In this case I will use 80. Even though we created a web server we should add a TCP endpoint of the worker role, since Node.js always listen on TCP instead of HTTP. And then changed the “index.js”, let our web server listen on 80. 1: var http = require("http"); 2: var port = 80; 3:  4: http.createServer(function (req, res) { 5: res.writeHead(200, { "Content-Type": "text/plain" }); 6: res.end("Hello World\n"); 7: }).listen(port); 8:  9: console.log("Server running at port %d", port); Then publish it to Windows Azure. And then in browser we can see our Node.js website was running on WACS worker role. We may encounter an error if we tried to run our Node.js website on 80 port at local emulator. This is because the compute emulator registered 80 and map the 80 endpoint to 81. But our Node.js cannot detect this operation. So when it tried to listen on 80 it will failed since 80 have been used.   Use NPM Modules When we are using WAWS to host Node.js, we can simply install modules we need, and then just publish or upload all files to WAWS. But if we are using WACS worker role, we have to do some extra steps to make the modules work. Assuming that we plan to use “express” in our application. Firstly of all we should download and install this module through NPM command. But after the install finished, they are just in the disk but not included in the worker role project. If we deploy the worker role right now the module will not be packaged and uploaded to azure. Hence we need to add them to the project. On solution explorer window click the “Show all files” button, select the “node_modules” folder and in the context menu select “Include In Project”. But that not enough. We also need to make all files in this module to “Copy always” or “Copy if newer”, so that they can be uploaded to azure with the “node.exe” and “index.js”. This is painful step since there might be many files in a module. So I created a small tool which can update a C# project file, make its all items as “Copy always”. The code is very simple. 1: static void Main(string[] args) 2: { 3: if (args.Length < 1) 4: { 5: Console.WriteLine("Usage: copyallalways [project file]"); 6: return; 7: } 8:  9: var proj = args[0]; 10: File.Copy(proj, string.Format("{0}.bak", proj)); 11:  12: var xml = new XmlDocument(); 13: xml.Load(proj); 14: var nsManager = new XmlNamespaceManager(xml.NameTable); 15: nsManager.AddNamespace("pf", "http://schemas.microsoft.com/developer/msbuild/2003"); 16:  17: // add the output setting to copy always 18: var contentNodes = xml.SelectNodes("//pf:Project/pf:ItemGroup/pf:Content", nsManager); 19: UpdateNodes(contentNodes, xml, nsManager); 20: var noneNodes = xml.SelectNodes("//pf:Project/pf:ItemGroup/pf:None", nsManager); 21: UpdateNodes(noneNodes, xml, nsManager); 22: xml.Save(proj); 23:  24: // remove the namespace attributes 25: var content = xml.InnerXml.Replace("<CopyToOutputDirectory xmlns=\"\">", "<CopyToOutputDirectory>"); 26: xml.LoadXml(content); 27: xml.Save(proj); 28: } 29:  30: static void UpdateNodes(XmlNodeList nodes, XmlDocument xml, XmlNamespaceManager nsManager) 31: { 32: foreach (XmlNode node in nodes) 33: { 34: var copyToOutputDirectoryNode = node.SelectSingleNode("pf:CopyToOutputDirectory", nsManager); 35: if (copyToOutputDirectoryNode == null) 36: { 37: var n = xml.CreateNode(XmlNodeType.Element, "CopyToOutputDirectory", null); 38: n.InnerText = "Always"; 39: node.AppendChild(n); 40: } 41: else 42: { 43: if (string.Compare(copyToOutputDirectoryNode.InnerText, "Always", true) != 0) 44: { 45: copyToOutputDirectoryNode.InnerText = "Always"; 46: } 47: } 48: } 49: } Please be careful when use this tool. I created only for demo so do not use it directly in a production environment. Unload the worker role project, execute this tool with the worker role project file name as the command line argument, it will set all items as “Copy always”. Then reload this worker role project. Now let’s change the “index.js” to use express. 1: var express = require("express"); 2: var app = express(); 3:  4: var port = 80; 5:  6: app.configure(function () { 7: }); 8:  9: app.get("/", function (req, res) { 10: res.send("Hello Node.js!"); 11: }); 12:  13: app.get("/User/:id", function (req, res) { 14: var id = req.params.id; 15: res.json({ 16: "id": id, 17: "name": "user " + id, 18: "company": "IGT" 19: }); 20: }); 21:  22: app.listen(port); Finally let’s publish it and have a look in browser.   Use Windows Azure SQL Database We can use Windows Azure SQL Database (a.k.a. WACD) from Node.js as well on worker role hosting. Since we can control the version of Node.js, here we can use x64 version of “node-sqlserver” now. This is better than if we host Node.js on WAWS since it only support x86. Just install the “node-sqlserver” module from NPM, copy the “sqlserver.node” from “Build\Release” folder to “Lib” folder. Include them in worker role project and run my tool to make them to “Copy always”. Finally update the “index.js” to use WASD. 1: var express = require("express"); 2: var sql = require("node-sqlserver"); 3:  4: var connectionString = "Driver={SQL Server Native Client 10.0};Server=tcp:{SERVER NAME}.database.windows.net,1433;Database={DATABASE NAME};Uid={LOGIN}@{SERVER NAME};Pwd={PASSWORD};Encrypt=yes;Connection Timeout=30;"; 5: var port = 80; 6:  7: var app = express(); 8:  9: app.configure(function () { 10: app.use(express.bodyParser()); 11: }); 12:  13: app.get("/", function (req, res) { 14: sql.open(connectionString, function (err, conn) { 15: if (err) { 16: console.log(err); 17: res.send(500, "Cannot open connection."); 18: } 19: else { 20: conn.queryRaw("SELECT * FROM [Resource]", function (err, results) { 21: if (err) { 22: console.log(err); 23: res.send(500, "Cannot retrieve records."); 24: } 25: else { 26: res.json(results); 27: } 28: }); 29: } 30: }); 31: }); 32:  33: app.get("/text/:key/:culture", function (req, res) { 34: sql.open(connectionString, function (err, conn) { 35: if (err) { 36: console.log(err); 37: res.send(500, "Cannot open connection."); 38: } 39: else { 40: var key = req.params.key; 41: var culture = req.params.culture; 42: var command = "SELECT * FROM [Resource] WHERE [Key] = '" + key + "' AND [Culture] = '" + culture + "'"; 43: conn.queryRaw(command, function (err, results) { 44: if (err) { 45: console.log(err); 46: res.send(500, "Cannot retrieve records."); 47: } 48: else { 49: res.json(results); 50: } 51: }); 52: } 53: }); 54: }); 55:  56: app.get("/sproc/:key/:culture", function (req, res) { 57: sql.open(connectionString, function (err, conn) { 58: if (err) { 59: console.log(err); 60: res.send(500, "Cannot open connection."); 61: } 62: else { 63: var key = req.params.key; 64: var culture = req.params.culture; 65: var command = "EXEC GetItem '" + key + "', '" + culture + "'"; 66: conn.queryRaw(command, function (err, results) { 67: if (err) { 68: console.log(err); 69: res.send(500, "Cannot retrieve records."); 70: } 71: else { 72: res.json(results); 73: } 74: }); 75: } 76: }); 77: }); 78:  79: app.post("/new", function (req, res) { 80: var key = req.body.key; 81: var culture = req.body.culture; 82: var val = req.body.val; 83:  84: sql.open(connectionString, function (err, conn) { 85: if (err) { 86: console.log(err); 87: res.send(500, "Cannot open connection."); 88: } 89: else { 90: var command = "INSERT INTO [Resource] VALUES ('" + key + "', '" + culture + "', N'" + val + "')"; 91: conn.queryRaw(command, function (err, results) { 92: if (err) { 93: console.log(err); 94: res.send(500, "Cannot retrieve records."); 95: } 96: else { 97: res.send(200, "Inserted Successful"); 98: } 99: }); 100: } 101: }); 102: }); 103:  104: app.listen(port); Publish to azure and now we can see our Node.js is working with WASD through x64 version “node-sqlserver”.   Summary In this post I demonstrated how to host our Node.js in Windows Azure Cloud Service worker role. By using worker role we can control the version of Node.js, as well as the entry code. And it’s possible to do some pre jobs before the Node.js application started. It also removed the IIS and IISNode limitation. I personally recommended to use worker role as our Node.js hosting. But there are some problem if you use the approach I mentioned here. The first one is, we need to set all JavaScript files and module files as “Copy always” or “Copy if newer” manually. The second one is, in this way we cannot retrieve the cloud service configuration information. For example, we defined the endpoint in worker role property but we also specified the listening port in Node.js hardcoded. It should be changed that our Node.js can retrieve the endpoint. But I can tell you it won’t be working here. In the next post I will describe another way to execute the “node.exe” and Node.js application, so that we can get the cloud service configuration in Node.js. I will also demonstrate how to use Windows Azure Storage from Node.js by using the Windows Azure Node.js SDK.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

• Using MAC Authentication for simple Web API’s consumption

  - by cibrax

  For simple scenarios of Web API consumption where identity delegation is not required, traditional http authentication schemas such as basic, certificates or digest are the most used nowadays. All these schemas rely on sending the caller credentials or some representation of it in every request message as part of the Authorization header, so they are prone to suffer phishing attacks if they are not correctly secured at transport level with https. In addition, most client applications typically authenticate two different things, the caller application and the user consuming the API on behalf of that application. For most cases, the schema is simplified by using a single set of username and password for authenticating both, making necessary to store those credentials temporally somewhere in memory. The true is that you can use two different identities, one for the user running the application, which you might authenticate just once during the first call when the application is initialized, and another identity for the application itself that you use on every call. Some cloud vendors like Windows Azure or Amazon Web Services have adopted an schema to authenticate the caller application based on a Message Authentication Code (MAC) generated with a symmetric algorithm using a key known by the two parties, the caller and the Web API. The caller must include a MAC as part of the Authorization header created from different pieces of information in the request message such as the address, the host, and some other headers. The Web API can authenticate the caller by using the key associated to it and validating the attached MAC in the request message. In that way, no credentials are sent as part of the request message, so there is no way an attacker to intercept the message and get access to those credentials. Anyways, this schema also suffers from some deficiencies that can generate attacks. For example, brute force can be still used to infer the key used for generating the MAC, and impersonate the original caller. This can be mitigated by renewing keys in a relative short period of time. This schema as any other can be complemented with transport security. Eran Rammer, one of the brains behind OAuth, has recently published an specification of a protocol based on MAC for Http authentication called Hawk. The initial version of the spec is available here. A curious fact is that the specification per se does not exist, and the specification itself is the code that Eran initially wrote using node.js. In that implementation, you can associate a key to an user, so once the MAC has been verified on the Web API, the user can be inferred from that key. Also a timestamp is used to avoid replay attacks. As a pet project, I decided to port that code to .NET using ASP.NET Web API, which is available also in github under https://github.com/pcibraro/hawknet Enjoy!.

• Should I choose Doctrine 2 or Propel 1.5/1.6, and why?

  - by Billy ONeal

  I'd like to hear from those who have used Doctrine 2 (or later) and Propel 1.5 (or later). Most comparisons between these two object relational mappers are based on old versions -- Doctrine 1 versus Propel 1.3/1.4, and both ORMs went through significant redesigns in their recent revisions. For example, most of the criticism of Propel seems to center around the "ModelName Peer" classes, which are deprecated in 1.5 in any case. Here's what I've accumulated so far (And I've tried to make this list as balanced as possible...): Propel Pros Extremely IDE friendly, because actual code is generated, instead of relying on PHP magic methods. This means IDE features like code completion are actually helpful. Fast (In terms of database usage -- no runtime introspection is done on the database) Clean migration between schema versions (at least in the 1.6 beta) Can generate PHP 5.3 models (i.e. namespaces) Easy to chain a lot of things into a single database query with things like useXxx methods. (See the "code completion" video above) Cons Requires an extra build step, namely building the model classes. Generated code needs rebuilt whenever Propel version is changed, a setting is changed, or the schema changes. This might be unintuitive to some and custom methods applied to the model are lost. (I think?) Some useful features (i.e. version behavior, schema migrations) are in beta status. Doctrine Pros More popular Doctrine Query Language can express potentially more complicated relationships between data than easily possible with Propel's ActiveRecord strategy. Easier to add reusable behaviors when compared with Propel. DocBlock based commenting for building the schema is embedded in the actual PHP instead of a separate XML file. Uses PHP 5.3 Namespaces everywhere Cons Requires learning an entirely new programming language (Doctrine Query Language) Implemented in terms of "magic methods" in several places, making IDE autocomplete worthless. Requires database introspection and thus is slightly slower than Propel by default; caching can remove this but the caching adds considerable complexity. Fewer behaviors are included in the core codebase. Several features Propel provides out of the box (such as Nested Set) are available only through extensions. Freakin' HUGE :) This I have gleaned though only through reading the documentation available for both tools -- I've not actually built anything yet. I'd like to hear from those who have used both tools though, to share their experience on pros/cons of each library, and what their recommendation is at this point :)

• The Database as Intellectual Property

  - by Jonathan Kehayias

  Every so often, a question shows up on the forums in the form of, “How do I prevent anyone from accessing my database schema, including local administrators and sysadmins in SQL Server?”  I usually laugh a little shake my head when I read a question like this because it demonstrates an complete lack of understanding of the power an administrator has over SQL Server.  The simple answer is this: If you don’t want your database schema to ever be accessed or known, don’t distribute your database....(read more)

• Reading/Writing Promoted Properties from BRE

  - by Sean Feldman

  ESB Toolkit Extensions is an open-source library giving you an extended BRE/BRI provider to read and write promoted properties of a message within business rules engine. I’ve used it to achieve automated process for mapping to canonical schema and then back to destination schema based on receiver ID as a promoted property (will blog on this later). A very useful library!

• Online SQL course [closed]

  - by Sualeh Fatehi

  Does anyone know of a free online SQL source that allows you to practice SQL online without installing a database? Sort of like Code Academy? I am looking to start teaching SQL to a remote audience, and I want to be able to set up a schema and some data, and have the students run SQL against my schema, and practice. I also want a way to set up some exercises for them. In short, a Code Academy kind of environment for SQL.

• some clarification on accept field in http request

  - by Salvador Dali

  Can anyone enlighten me on the following question: What do different fields in accept field in HTTP request mean? I can understand the basics that through accept the client is telling the server what type of information it is waiting to receive, so for example: Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 This way the client will tell the server that it can understand three following formats: text/html application/xhtml+xml application/xml But can someone tell me what this q values mean and that / Also if I have any flaws in my understanding - please tell me.

• Lync server 2010 Active Directory Preparation with a Windows Server 2003 DC

  - by juFo

  I'm trying to install Lync server 2010 but i'm stuck for a while now with the "Active Directory Preparation" part of the Lync server 2010 installation. The "Prepare Schema" fails with the following error: "Step 1: Prepare Schema Run once per deployment. Extends the schema for Lync Server. Not Available: Failure occurred while attempting to check the schema state. Please ensure Active Directory is reachable." screenshot: https://skydrive.live.com/#cid=CB15F1A932B364BE&id=CB15F1A932B364BE%211742 The situation: 1 server with Windows Server 2003 (x86), which is the only Domain Controller (DC) 1 server with Windows Server 2008 R2 (x64) where Lync should be installed. First I have found that the DFL/FFL were not correct: On the DC (server2003) I have changed the Domain Functional Level to Windows Server 2003 and also the Forest Functional Level to Windows Server 2003. If I check these settings on the Server2008 with Active Directory Domains and Trusts, I see indeed that the DFL and FFL are being set to Windows Server 2003. (Windows Server 2003 is the minimum required for Lync server 2010) I tried the Lync AD Preparation again but still got the same message: https://skydrive.live.com/#cid=CB15F1A932B364BE&id=CB15F1A932B364BE%211742 I'm logged in on the Server2008 and Server2003 with the domain administrator account. If I check "Active Directory Users and Computers" and go to the directory Users and watch the properties from the Administrator User then it is also a Member of: Domain Admins Domain Users Enterprise Admins Schema Admins Group Policy Creator Owners The firewall on the server2008 is turned off, still nog working So now my question is: what should I do to make the Lync setup (Active Directory Preparation) work? (I would appreciate clear step-by-step suggestions to check.) Thanks in advance. Update 1: Now I've extended AD successfully on the 2003 DC, using this link: http://blogs.pointbridge.com/Blogs/sloan_jason/Pages/Post.aspx?_ID=2 but when I check the Active Directory Preparation again on the Lync install, it still gives me the same error as in the screenshot I've provided. Update 2: I found out that there is a log on "C:\Users\\AppData\Local\Temp\ with this: Get-CSDomainState Get Domain State Error: An error occurred: "Microsoft.Rtc.Management.ADConnect.NoSuitableServerFoundException" "No suitable domain controller was found in domain "OurDomain.LOCAL". Errors:\r\n"OurDCserver.OurDomain.LOCAL5.2 (3790)5.2 (3790) Service Pack1OurDCserver.OurDomain.LOCAL5.2 (3790)5.2 (3790)Service Pack 1"" I thought Lync could be installed with a Windows Server 2003 (according to the documentation on technet) and it doesn't require a SP. :s

• What's the difference between one-dash and two-dashes for command prompt parameters?

  - by Pacerier

  I was wondering why is it that some programs requires their command prompt parameters to have two dashes in front whereas some (most) only require one dash in front? For example most programs look like this: relaxer -dtd toc.xml toc_gr.xml toc_jp.xml Whereas some programs look like this: xmllint --valid toc.xml --noout What's the reason that some requires two dashes instead of one? Doesn't it make sense for everyone to stick to one standard (i.e. a single dash will do).

• How can I tell Notepad++ to always use a particular language with a particular file extension.

  - by MatrixFrog

  I've associated .xul with Notepad++ so if I double-click on a .xul file, it will open in Notepad++. But Notepad++ doesn't know that XUL is just a particular type of XML, so I then have to manually click on "Language XML" to get XML syntax highlighting. Is there a way that I can tell it: "every time you open a file with the extension .xul, automatically switch to the XML language"?

• Including configuration files while compiling a Flex application with MXMLC

  - by Daniel

  Hello there, I'm using: - Flex SDK 3.5.0 - Parsley 2.2.2. - Flash Builder 4 Down in my src folder (which is configured as part of the source path in the Flash Builder), I have a logging.xml which I configure via Parsley: FlexLoggingXmlSupport.initialize(); XmlContextBuilder.build("com/company/product/util/log/logging.xml"); When I run my application through Flash Builder, the XmlContentBuilder seems to locate the logging.xml (the implementation is a regular URLLoader one). When I compile my application using MXMLC (whether in Ant or command-line), and then run the swf, I get the following error: Cause(0): Error loading com/company/product/util/log/logging.xml: Error in URLLoader - cause: Error #2032: Stream Error. URL: file:///C|/workspace/folder01/product/target/com/company/product/util/log/logging.xml - cause: Error #2032: Stream Error. URL: file:///C|/workspace/folder01/product/target/com/company/product/util/log/logging.xml Here is the MXMLC tag in Ant: <mxmlc file="${product.src.dir}/com/company/product/view/Main.mxml" output="${product.target.dir}/${product.release.filename}" keep-generated-actionscript="false"> <load-config filename="${FLEX_HOME}/frameworks/flex-config.xml" /> <!-- source paths --> <source-path path-element="${FLEX_HOME}/frameworks" /> <compiler.source-path path-element="${product.src.dir}" /> <compiler.source-path path-element="${product.locale.dir}/{locale}" /> <compiler.library-path dir="${product.basedir}" append="true"> <include name="libs" /> </compiler.library-path> <warnings>false</warnings> <debug>false</debug> </mxmlc> And here is the command line: \mxmlc.exe -output "C:\temp\Rap.swf" -load-config "C:\Program Files\Adobe\Adobe Flash Builder 4 Plug-in\sdks\3.5.0\frameworks\flex-config.xml" -source-path "C:\Program Files\Adobe\Adobe Flash Builder 4 Plug-in\sdks\3.5.0\frameworks" C:\workspace\folder01\product\src C:\workspace\folder01\product\locale\en_US -library-path+=C:\workspace\folder01\product\libs -file-specs C:\workspace\folder01\product\src\com\company\product\view\main.mxml Now perhaps I don't get this correctly, but as far as I understand the SWF should be compiled with all of the resources in the paths I give MXMLC as source-paths. For some reason it seems that the XML file is not compiled into the SWF, hence the relative path of the XmlContentBuilder isn't located successfully. I could not find any argument to provide the MXMLC with that might solve this. I tried using the -dump-config option with the Flash Builder's compiler, then giving that configuration to MXMLC, but it didn't work either. I tried providing the XmlContentBuilder with an absolute path. That worked fine when I compiled with MXMLC via Ant, but still didn't work when I used MXMLC in the command-line... I'd be happy to be enlightened here, regarding all subjects - using MXMLC, accessing resources with relative paths, configuring logging in Parsley, etc. Many thanks in advance, Daniel
