• Appropriate response when client empowered with CMS destroys content to his own will

  - by dukeofgaming

  So, I just recently closed a website project that pretty much was The Oatmeals' Design Hell, but with content. The client loved the site at the beginning but started getting other people involved and mercilessly bombarding us with their opinions. We served a carefully thought content strategy (which the client approved) and extremely curated copywriting that took us four months after at least 5 requirement changes (new content, new objectives for the business, changed offerings, new mindfaps, etc.) that required us to rewrite the content about 3 times. The client never gave timely feedback even though we kept the process open for him and his people to see (content being developed transparently in Google Docs). Near the end of the project he still wanted to make changes but wanted us to finish already (there are not enough words in the world to even try to make sense of this). So I explained to him the obvious implications of the never-ending requirement changes and advised him to take the time to gather his thoughts with his own team and see the new content introduced as a new content maintenance project. He happily accepted, but on the day of training/delivery things went very wrong and we have no idea why. The client didn't even allow the site to be out for a week with the content we developed for him and quickly replaced us with a Joomla savvy intern so that he completely destroy the content with shallow, unstructured, tasteless and plain wordsmithing (and I'm not even being visceral). Worst insult of all, he revoked our access from his server and the deployed CMS not even having passed 10 minutes of being given his administrator account (we realized the day after that he did it in our own office, the nerve!). Everybody involved in the team is enraged and insulted. I never want to see this happen again. So, to try to make sense of this situation and avoid it in the future with new clients I have two concrete questions: Is there even an appropriate course of action with a client like this?, or is he just not worth the trouble of analyzing (blindly hoping this never repeats again). In the exercise to try and blame ourselves instead of the client and take this as a lesson of... something, how should we set expectations for new clients about the working terms, process and final product so that they are discouraged from mauling the content to their own contempt once they get the codes to the nukes (access to the CMS)?

• ldap client cannot contact ldap server

  - by Van

  I have followed these instructions: https://help.ubuntu.com/12.04/serverguide/openldap-server.html#openldap-auth-config The ldap server works fine. I can log into it using an ldap account. However, I configured another Ubuntu 12.04 server as a ldap client for authentication but I cannot contact the server. Here is the error: On the client: # ldapsearch -Q -LLL -Y EXTERNAL -H ldapi://ldap01.domain.local -b cn=config dn ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1) The server can receive requests: On the client: # telnet ldap01.domain.local 389 Trying 10.3.17.10...

• BPM ADF Task forms. Checking whether the current user is in a BPM Swimlane

  - by Christopher Karl Chan

  @page { margin: 0.79in } P { margin-bottom: 0.08in } --Focus So this blog entry will focus on BPM Swimlane roles and users from a ADF context. So we have an ADF Task Details Form and we are in the process of making it richer and dynamic in functionality. A common requirement could be to dynamically show different areas based on the user logged into the workspace. Perhaps even we want to know even what swim-lane role the user belongs to. It is is a little bit harder to achieve then one thinks unless you know the trick. The Challenge The tricky part here is that the ADF Task Details Form is in fact part of a separate J2EE application to the main workspace. So if you try to use Java or Expression Language to get the logged in user you will only find anonymous and none of the BPM Roles you will be expecting. So what to do? The Magic First add the BC4J Security library to your view project. Then Restart JDeveloper. Now find the web.xml file in the view project of your ADF Task Details Application and look for the JpsFilter section. Then add in the following section. <init-param> <param-name>application.name</param-name> <param-value>OracleBPMProcessRolesApp</param-value></init-param> This will link your application to that of the BPM workspace. Then in your dynamic part of your ADF form you can now check whether the user logged into the BPM Workspace belongs in a BPM swim-lane in any BPM process. The best way to do this is by using expression language in the JSF page itself. Here I am simply changing the rendered flag to either true or false and thereby hiding or showing a section. Perhaps you are re-using the same form for a task in an approver swim-lane and ordinary user swimlane. So we only want the approver to see this field. So call the built in function to check if the user is a member of the BPM swim-lane role. The name of the role must be of the syntax BPMProject.RoleName <af:outputText value="This will only be rendered when the user is part of the BPM Swimlane Role rendered="#{securityContext.userInRole['BPMProjectName.Rolename']}"/> Now you must redeploy your ADF Task Form project Now (in the image above) the text will ONLY get rendered in the Task Details Form only if the user logged into the workspace is a member of the swimlane Unsecure of the BPM project SimpleTask

• Writing an ASP.Net Web based TFS Client

  - by Glav

  So one of the things I needed to do was write an ASP.Net MVC based application for our senior execs to manage a set of arbitrary attributes against stories, bugs etc to be able to attribute whether the item was related to Research and Development, and if so, what kind. We are using TFS Azure and don’t have the option of custom templates. I have decided on using a string based field within the template that is not very visible and which we don’t use to write a small set of custom which will determine the research and development association. However, this string munging on the field is not very user friendly so we need a simple tool that can display attributes against items in a simple dropdown list or something similar. Enter a custom web app that accesses our TFS items in Azure (Note: We are also using Visual Studio 2012) Now TFS Azure uses your Live ID and it is not really possible to easily do this in a server based app where no interaction is available. Even if you capture the Live ID credentials yourself and try to submit them to TFS Azure, it wont work. Bottom line is that it is not straightforward nor obvious what you have to do. In fact, it is a real pain to find and there are some answers out there which don’t appear to be answers at all given they didn’t work in my scenario. So for anyone else who wants to do this, here is a simple breakdown on what you have to do: Go here and get the “TFS Service Credential Viewer”. Install it, run it and connect to your TFS instance in azure and create a service account. Note the username and password exactly as it presents it to you. This is the magic identity that will allow unattended, programmatic access. Without this step, don’t bother trying to do anything else. In your MVC app, reference the following assemblies from “C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ReferenceAssemblies\v2.0”: Microsoft.TeamFoundation.Client.dll Microsoft.TeamFoundation.Common.dll Microsoft.TeamFoundation.VersionControl.Client.dll Microsoft.TeamFoundation.VersionControl.Common.dll Microsoft.TeamFoundation.WorkItemTracking.Client.DataStoreLoader.dll Microsoft.TeamFoundation.WorkItemTracking.Client.dll Microsoft.TeamFoundation.WorkItemTracking.Common.dll If hosting this in Internet Information Server, for the application pool this app runs under, you will need to enable 32 Bit support. You also have to allow the TFS client assemblies to store a cache of files on your system. If you don’t do this, you will authenticate fine, but then get an exception saying that it is unable to access the cache at some directory path when you query work items. You can set this up by adding the following to your web.config, in the <appSettings> element as shown below: <appSettings> <!-- Add reference to TFS Client Cache --> <add key="WorkItemTrackingCacheRoot" value="C:\windows\temp" /> </appSettings> With all that in place, you can write the following code: var token = new Microsoft.TeamFoundation.Client.SimpleWebTokenCredential("{you-service-account-name", "{your-service-acct-password}"); var clientCreds = new Microsoft.TeamFoundation.Client.TfsClientCredentials(token); var currentCollection = new TfsTeamProjectCollection(new Uri(“https://{yourdomain}.visualstudio.com/defaultcollection”), clientCreds); TfsConfigurationServercurrentCollection.EnsureAuthenticated(); In the above code, not the URL contains the “defaultcollection” at the end of the URL. Obviously replace {yourdomain} with whatever is defined for your TFS in Azure instance. In addition, make sure the service user account and password that was generated in the first step is substituted in here. Note: If something is not right, the “EnsureAuthenticated()” call will throw an exception with the message being you are not authorised. If you forget the “defaultcollection” on the URL, it will still fail but with a message saying you are not authorised. That is, a similar but different exception message. And that is it. You can then query the collection using something like: var service = currentCollection.GetService<WorkItemStore>(); var proj = service.Projects[0]; var allQueries = proj.StoredQueries; for (int qcnt = 0; qcnt < allQueries.Count; qcnt++) {     var query = allQueries[qcnt];     var queryDesc = string.format(“Query found named: {0}”,query.Name); } You get the idea. If you search around, you will find references to the ServiceIdentityCredentialProvider which is referenced in this article. I had no luck with this method and it all looked too hard since it required an extra KB article and other magic sauce. So I hope that helps. This article certainly would have helped me save a boat load of time and frustration.

• SP1 of RadControls for WinForms Q1 2010 released, featuring VS2010 and Client Profile support

  As always, Telerik's plans were closely aligned with Microsoft's release schedule, and we were dedicated to provide VS2010 support even before Visual Studio 2010 was officially launched. Now that the first VS2010 launch event is over, here comes the first of many Telerik Service Packs to support VS2010. This RadControls for WinForms release is the first to provide support for the Client Profile, introduced with .NET3.5, and now default when starting new windows forms projects with VS2010. The Client Profile is a smaller version of the.NET Framework that includes only the assemblies needed for deploying client-based applications, which in turn reduces the size of the application. Basically, the Design time classes are excluded from the Client Profile (CP), because they are only needed for designing and not for running an application. In Q1 2010 SP1 we have moved the designer classes from the run-time assemblies to a new dedicated assembly (Telerik.WinControls.UI.Design.dll), ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  Hi all , I urgently need your help . I am new to consuming a web service using SOAP protocol. I have been given a demo webservice URL which ends in .WSDL and NOT .asml?WSDL. The problem is I cannot add a web reference using Visual studio OR Disco.exe or Wsdl.exe - This webservice has been created on a java platform and for security reasons the only way to make a invoke the webservice is at runtime using SOAP protocol IN asp.net (VB). I I have created some code but cannot seem to send the soap object to the receiving web service. If I could get a solution with step by step instructions on how I can send a SOAP REQUEST. Below is my code and all am trying to do is send a SOAP REQUEST and receive a SOAP RESPONSE which I will display in my browser. <%@ page language="vb" %> <%@ Import Namespace="System.Data"%> <%@ Import Namespace="System.Xml"%> <%@ Import Namespace="System.Net"%> <%@ Import Namespace="System.IO"%> <%@ Import Namespace="System.Text"%> <script runat=server> Private Sub Page_Load() Dim objHTTPReq As HttpWebRequest Dim WebserviceUrl As String = "http://xx.xx.xx:8084/asy/wsdl/asy.wsdl" objHTTPReq = CType(WebRequest.Create(WebserviceUrl), HttpWebRequest) Dim soapXML As String soapXML = "<?xml version='1.0' encoding='utf-8'?>" & _ " <soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'" & _ " xmlns:xsd='http://www.w3.org/2001/XMLSchema'"& _ " xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/' >"& _ " <soap:Body> "& _ " <validatePaymentData xmlns='http://asybanks.webservices.asycuda.org'> " & _ " <bankCode>"& bankCode &"</bankCode> " & _ " <PaymentDataType>" & _ " <paymentType>"& payment_type &"</paymentType> " & _ " <amount>"& ass_amount &"</amount> " & _ " <ReferenceType>" & _ " <year>"& year &"</year> " & _ " <customsOfficeCode>"& station &"</customsOfficeCode> " & _ " </ReferenceType>" & _ " <accountNumber>"& zra_account &"</accountNumber> " & _ " </PaymentDataType> " & _ " </validatePaymentData> " & _ " </soap:Body> " & _ " </soap:Envelope> " objHTTPReq.Headers.Add("SOAPAction", "http://asybanks.webservices.asycuda.org") objHTTPReq.ContentType = "text/xml; charset=utf-8" objHTTPReq.ContentLength = soapXML.Length objHTTPReq.Accept = "text/xml" objHTTPReq.Method = "POST" Dim objHTTPRes As HttpWebResponse = CType(objHTTPReq.GetResponse(), HttpWebResponse) Dim dataStream As Stream = objHTTPRes.GetResponseStream() Dim reader As StreamReader = new StreamReader(dataStream) Dim responseFromServer As String = reader.ReadToEnd() OurXml.text = responseFromServer End Sub </script> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title> XML TRANSACTION SIMULATION - N@W@ TJ </title> </head> <body> <form id="form1" runat="server"> <div> <p>ZRA test Feedback:</p> <asp:label id="OurXml" runat="server"/> </div> </form> </body> </html> the demo webservice looks like this: <?xml version="1.0" encoding="UTF-8" ?> - <!-- WEB SERVICE JAVA DEMO --> - <definitions targetNamespace="http://asybanks.webservices.asycuda.org" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:y="http://asybanks.webservices.asycuda.org"> - <types> - <xs:schema elementFormDefault="qualified" targetNamespace="http://asybanks.webservices.asycuda.org" xmlns="http://www.w3.org/2001/XMLSchema"> SOME OTHER INFORMATION AT THE BOTTOM <soap:address location="http://xx.xx.xx:8084/asy/services/asy" /> </port> </service> </definitions> From the above excerpt of the wsdl url webservice, I am not sure which namespace to use for soapACTION - please advise....

• PASS Summit 2012: keynote and Mobile BI announcements #sqlpass

  - by Marco Russo (SQLBI)

  Today at PASS Summit 2012 there have been several announcements during the keynote. Moreover, other news have not been highlighted in the keynote but are equally if not more important for the BI community. Let’s start from the big news in the keynote (other details on SQL Server Blog): Hekaton: this is the codename for in-memory OLTP technology that will appear (I suppose) in the next release of the SQL Server relational engine. The improvement in performance and scalability is impressive and it enables new scenarios. I’m curious to see whether it can be used also to improve ETL performance and how it differs from using SSD technology. Updates on Columnstore: In the next major release of SQL Server the columnstore indexes will be updatable and it will be possible to create a clustered index with Columnstore index. This is really a great news for near real-time reporting needs! Polybase: in 2013 it will debut SQL Server 2012 Parallel Data Warehouse (PDW), which will include the Polybase technology. By using Polybase a single T-SQL query will run queries across relational data and Hadoop data. A single query language for both. Sounds really interesting for using BigData in a more integrated way with existing relational databases. And, of course, to load a data warehouse using BigData, which is the ultimate goal that we all BI Pro have, right? SQL Server 2012 SP1: the Service Pack 1 for SQL Server 2012 is available now and it enable the use of PowerPivot for SharePoint and Power View on a SharePoint 2013 installation with Excel 2013. Power View works with Multidimensional cube: the long-awaited feature of being able to use PowerPivot with Multidimensional cubes has been shown by Amir Netz in an amazing demonstration during the keynote. The interesting thing is that the data model behind was based on a many-to-many relationship (something that is not fully supported by Power View with Tabular models). Another interesting aspect is that it is Analysis Services 2012 that supports DAX queries run on a Multidimensional model, enabling the use of any future tool generating DAX queries on top of a Multidimensional model. There are still no info about availability by now, but this is *not* included in SQL Server 2012 SP1. So what about Mobile BI? Well, even if not announced during the keynote, there is a dedicated session on this topic and there are very important news in this area: iOS, Android and Microsoft mobile platforms: the commitment is to get data exploration and visualization capabilities working within June 2013. This should impact at least Power View and SharePoint/Excel Services. This is the type of UI experience we are all waiting for, in order to satisfy the requests coming from users and customers. The important news here is that native applications will be available for both iOS and Windows 8 so it seems that Android will be supported initially only through the web. Unfortunately we haven’t seen any demo, so it’s not clear what will be the offline navigation experience (and whether there will be one). But at least we know that Microsoft is working on native applications in this area. I’m not too surprised that HTML5 is not the magic bullet for all the platforms. The next PASS Business Analytics conference in 2013 seems a good place to see this in action, even if I hope we don’t have to wait other six months before seeing some demo of native BI applications on mobile platforms! Viewing Reporting Services reports on iPad is supported starting with SQL Server 2012 SP1, which has been released today. This is another good reason to install SP1 on SQL Server 2012. If you are at PASS Summit 2012, come and join me, Alberto Ferrari and Chris Webb at our book signing event tomorrow, Thursday 8 2012, at the bookstore between 12:00pm and 12:30pm, or follow one of our sessions!

• Moving all UI logic to Client Side?

  - by Mag20

  Our team originally consisted of mostly server side developers with minimum expertise in Javascript. In ASP.NET we used to write a lot of UI logic in code-behind or more recently through controllers in MVC. A little while ago 2 high level client side developers joined our team. They can do in HTMl/CSS/Javascript pretty much anything that we could previously do with server-side code and server-side web controls: Show/hide controls Do validation Control AJAX refreshing So I started to think that maybe it would be more efficient to just create a high level API around our business logic, kinda like Amazon Fulfillment API: http://docs.amazonwebservices.com/fws/latest/APIReference/, so that client side developers would fully take over the UI, while server side developers would only concentrate on business logic. So for ordering system you would have a high level API like: OrderService.asmx CreateOrderResponse CreateOrder(CreateOrderRequest) AddOrderItem AddPayment - SubmitPayment - GetOrderByID FindOrdersByCriteria ... There would be JSON/REST access to API, so it would be easy to consume from client-side UI. We could use this API for both internal UI development and also for 3-rd parties to create their own applications. With advances in Javascript and availability of good client side developers, is it a good time to get rid of code-behind/controllers and just concentrate on developing high level APIs (ala Amazon) that client side developers can consume?

• How should I setup billing for AdWords when managing a client's campaign in My Client Center? [closed]

  - by Dustin

  I have worked with Google AdWords before and will now be managing an AdWords account for a client. I have a My Client Center account, but I'm wondering what the best practices are for billing. Should I link billing to my own credit card and then have the client pay me (they have to pay me to manage the account anyway), or should I have the client pay Google directly? How is this usually done? If it is the later, what is the best way to have them input their payment info?

• How should I capture clickstream data?

  - by editor

  I'd like to start using clickstream analysis to improve a dynamic site's user experience. I'd like to rule out two options: parameterizing URLs (index.php?src=http://www.example.com) and immediate database logging. The former makes pretty ugly URLs and isn't great for SEO and the latter might slow down page render when there are lots of concurrent users. Assuming these aren't viable options, I think I'm left with doing an asynchronous POST to a server side script that runs a database query and returns a 204 (no data) response. Is this the best option for capturing clickstream data?

• Client and Server game update speed

  - by user20686

  I am working on a simple two player networked asteroids game using XNA and the Lidgren networking library. For this set up I have a Lidgren server maintaining what I want to be the true state of the game, and the XNA game is the Lidgren client. The client sends key inputs to the server, and the server process the key inputs against game logic, sending back updates. (This seemed like a better idea then sending local positions to the server.) The client also processes the key inputs on its own, so as to not have any visible lag, and then interpolates between the local position and remote position. Based on what I have been reading this is the correct way to smooth out a networked game. The only thing I don’t get is what value to use as the time deltas. Currently every message the server sends it also sends a delta-time update with it, which is time between the last update. The client then saves this delta time to use for its local position updates, so they can be using roughly the same time deltas to calculate position updates. I know the XNA game update gets called 60 times a second, so I set my server to update the game state at the same speed. This will probably only work as long as the game is working on a fixed time step and will probably cause problems if I want to change that in the future. The server sends updates to clients on another thread, which runs at 10 updates per second to cut down on bandwidth. I do not see noticeable lag in movement and over time if no user input is received the local and remote positions converge on each other as they should. I am also not currently calculating for any latency as I am trying to go one step at a time. So my question is should the XNA client be using its current game time to update the local game state and not being using time deltas sent by the server? If I should be using the clients time delta between updates how do I keep it in-line with how fast the server is updating its game state?

• Java RMI cannot connect to host from external client.

  I've been using RMI in this project for a while. I've gotten the client program to connect (amongst other things) to the server when running it over my LAN, however when running it over the internet I'm running into the following exception: java.rmi.ConnectException: Connection refused to host: (private IP of host machine); nested exception is: java.net.ConnectException: Connection timed out: connect at sun.rmi.transport.tcp.TCPEndpoint.newSocket(Unknown Source) at sun.rmi.transport.tcp.TCPChannel.createConnection(Unknown Source) at sun.rmi.transport.tcp.TCPChannel.newConnection(Unknown Source) at sun.rmi.server.UnicastRef.invoke(Unknown Source) at java.rmi.server.RemoteObjectInvocationHandler.invokeRemoteMethod(Unknown Source) at java.rmi.server.RemoteObjectInvocationHandler.invoke(Unknown Source) at $Proxy1.ping(Unknown Source) at client.Launcher$PingLabel.runPing(Launcher.java:366) at client.Launcher$PingLabel.<init>(Launcher.java:353) at client.Launcher.setupContentPane(Launcher.java:112) at client.Launcher.<init>(Launcher.java:99) at client.Launcher.main(Launcher.java:59) Caused by: java.net.ConnectException: Connection timed out: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(Unknown Source) at java.net.PlainSocketImpl.connectToAddress(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.SocksSocketImpl.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.<init>(Unknown Source) at java.net.Socket.<init>(Unknown Source) at sun.rmi.transport.proxy.RMIDirectSocketFactory.createSocket(Unknown Source) at sun.rmi.transport.proxy.RMIMasterSocketFactory.createSocket(Unknown Source) ... 12 more This error is remeniscent of my early implementation of RMI and I can obtain the error verbatum if I run the client locally without the server program running as well.

Here's the server initiation: public static void main(String args[]) { try { GameServer gobj = new GameServer(); Information gstub = (Information) UnicastRemoteObject.exportObject( gobj, 1099); Registry registry = LocateRegistry.createRegistry(1099); registry.bind("Game Server", gstub); LoginServer lobj = new LoginServer(gobj); Login lstub = (Login) UnicastRemoteObject.exportObject(lobj, 7099); // Bind the remote object's stub in the registry registry.bind("Login Server", lstub); System.out.println("Server ready"); } catch (Exception e) { System.err.println("Server exception: " + e.toString()); e.printStackTrace(); } } Bad practice with the catch(Exception e) I know but bear with me. Up to this stage I know it works fine over the LAN, here's where the exception occurs over the WAN and is the first place a method in the server is called: private class PingLabel extends JLabel { private static final long serialVersionUID = 1L; public PingLabel() { super(""); runPing(); } public void setText(String text) { super.setText("Ping: " + text + "ms"); } public void runPing() { try { PingThread pt = new PingThread(); gameServer.ping(); pt.setRecieved(true); setText("" + pt.getTime()); } catch (RemoteException e) { e.printStackTrace(); } } } That's a label placed on the launcher as a ping test. the method ping(), in gameserver does nothing, as in is a null method. It's worth noting also that ports 1099 and 7099 are forwarded to the server machine (which should be obvious from the stack trace). Can anyone see anyting I'm missing/doing wrong? If you need any more information just ask. EDIT: I'm practically certain the problem has nothing to do with my router settings. When disabling my port forwarding settings I get a slightly different error: Client exception: java.rmi.ConnectException: Connection refused to host: (-WAN IP NOT LOCAL IP-); but it appears both on the machine locally connected to the server and on the remote machine. In addition, I got it to work seamlessly when connecting the server straight tho the modem (cutting out the router. I can only conclude the problem is in my router's settings but can't see where (I've checked and double checked the port forwarding page). That's the only answer i can come up with.

• Deployment Options for AutoVue 20.0 Users

  - by celine.beck

  AutoVue release 20.0 boasts a brand new architecture. As part of this product rearchitecture, AutoVue can now be deployed either as a desktop deployment to serve the needs of individual users in their personal productivity; or in a Client / Server deployment for those that require connections to enterprise applications / back-end systems. The most common question that we hear from our customers about this new architecture is the following: "Is AutoVue Desktop Version still part of release 20.0 and if so, what is the difference between AutoVue Desktop Version and the Desktop deployment of AutoVue release 20.0?" A detailed answer to these questions is provided in a very complete article entitled Understanding Deployment Options for AutoVue 19.3 Desktop Version users upgrading to AutoVue 20.0 (note 1058254.1) which was posted on My Oracle Support. Is AutoVue Desktop Version still part of AutoVue 20.0? Yes, AutoVue Desktop Version 20.0 is still available to customers and partners, as a maintenance release of AutoVue 19.3. As such, it will not contain any of the new capabilities featured in AutoVue release 20.0. All format enhancements and new format support have been added to release 20.0 Desktop Version though. What is the different between AutoVue Desktop Version 20.0 and the Desktop Deployment of AutoVue release 20.0? AutoVue 20.0 Desktop deployment works like the AutoVue Desktop version. It is installed as a standalone product on each user's machine and runs a local instance of AutoVue. The AutoVue 20.0 Desktop deployment includes all new features, formats and performance enhancements included in release 20.0 (walkthrough capability, improved compare, ...) What deployment options are available to AutoVue 19.3 Desktop Version customers? AutoVue Desktop Version users can evolve at their own pace to the new AutoVue platform. With release 20.0, customers can opt to: Option 1: Stay on AutoVue Desktop Version 20.0 Option 2: Migrate to AutoVue and select the desktop deployment method Option 3: Migrate to AutoVue and select the Client/Server deployment method What is the Client / Server deployment of AutoVue 20.0? The Client/Server deployment has AutoVue installed on a server, to which local client machines connect to access and view documents. AutoVue 20.0 Client Server Deployment allows users to leverage the new online/offline capabilities in release 20.0 and easily switch between online and offline modes of operation. With the Client/Server deployment, customers also get a complete, open and standards-based set of integration tools that allows them to tie AutoVue to any enterprise applications to provide users with a consistent view of data and business objects and expand workflow automation to document-based processes.

• Suggestions for connecting .NET WPF GUI with Java SE Server

  - by Sam Goldberg

  BACKGROUND We are building a Java (SE) trading application which will be monitoring market data and sending trade messages based on the market data, and also on user defined configuration parameters. We are planning to provide the user with a thin client, built in .NET (WPF) for managing the parameters, controlling the server behavior, and viewing the current state of the trading. The client doesn't need real-time updates; it will instead update the view once every few seconds (or whatever interval is configured by the user). The client has about 6 different operations it needs to perform with the server, for example: CRUD with configuration parameters query subset of the data receive updates of current positions from server It is possible that most of the different operations (except for receiving data) are just different flavors of managing the configuration parameters, but it's too early in our analysis for us to be sure. To connect the client with the server, we have been considering using: SOAP Web Service RESTful service building a custom TCP/IP based API (text or xml) (least preferred - but we use this approach with other applications we have) As best as I understand, pros and cons of the different web service flavors are: SOAP pro: totally automated in .NET (and Java), modifying server side interface require no code changes in communication layer, just running refresh on Web Service reference to regenerate the classes. con: more overhead in the communication layer sending more text, etc. We're not using J2EE container so maybe doesn't work so well with J2SE REST pro: lighter weight, less data. Has good .NET and Java support. (I don't have any real experience with this, so don't know what other benefits it has.) con: client will not be automatically aware if there are any new operations or properties added (?), so communication layer needs to be updated by developer if server interface changes. con: (both approaches) Server cannot really push updates to the client at regular intervals (?) (However, we won't mind if client polls the server to get updates.) QUESTION What are your opinions on the above options or suggestions for other ways to connect the 2 parts? (Ideally, we don't want to put much work into the communication layer, because it's not the significant part of the application so the more off-the-shelf and automated the better.)

• curl FTPS with client certificate to a vsftpd

  - by weeheavy

  I'd like to authenticate FTP clients either via username+password or a client certificate. Only FTPS is allowed. User/password works, but while testing with curl (I don't have another option) and a client certificate, I need to pass a user. Isn't it technically possible to authenticate only by providing a certificate? vsftpd.conf passwd_chroot_enable=YES chroot_local_user=YES ssl_enable=YES rsa_cert_file=usrlocal/ssl/certs/vsftpd.pem force_local_data_ssl=YES force_local_logins_ssl=YES Tested with curl -v -k -E client-crt.pem --ftp-ssl-reqd ftp://server:21/testfile the output is: * SSLv3, TLS handshake, Client hello (1): * SSLv3, TLS handshake, Server hello (2): * SSLv3, TLS handshake, CERT (11): * SSLv3, TLS handshake, Request CERT (13): * SSLv3, TLS handshake, Server finished (14): * SSLv3, TLS handshake, CERT (11): * SSLv3, TLS handshake, Client key exchange (16): * SSLv3, TLS handshake, CERT verify (15): * SSLv3, TLS change cipher, Client hello (1): * SSLv3, TLS handshake, Finished (20): * SSLv3, TLS change cipher, Client hello (1): * SSLv3, TLS handshake, Finished (20): * SSL connection using DES-CBC3-SHA * Server certificate: * SSL certificate verify result: self signed certificate (18), continuing anyway. > USER anonymous < 530 Anonymous sessions may not use encryption. * Access denied: 530 * Closing connection #0 * SSLv3, TLS alert, Client hello (1): curl: (67) Access denied: 530 This is theoretically ok, as i forbid anonymous access. If I specify a user with -u username:pass it works, but it would without a certificate too. The client certificate seems to be ok, it looks like this: client-crt.pem -----BEGIN RSA PRIVATE KEY----- content -----END RSA PRIVATE KEY----- -----BEGIN CERTIFICATE----- content -----END CERTIFICATE----- What am I missing? Thanks in advance. (The OS is Solaris 10 SPARC).
