  • Difference between spring setter and interface injection?

    - by Satish Pandey
    I know how constructor and setter injection works in spring. Normally I use interfaces instead of classes to inject beans using setter and I consider it as interface injection, but in case of constructor we also use interfaces (I am confused). In following example I use JobProcessor interface instead of JobProcessorImpl class. public class JobScheduler { // JobProcessor interface private JobProcessor jobProcessor; // Dependecy injection public void setJobProcessor(JobProcessor jobProcessor){ this.jobProcessor = jobProcessor; } } I tried to find a solution by googling but there are different opinions by writers. Even some people says that spring doesn't support interface injection in their blogs/statements. Can someone help me by example?

  • Japanese text garbled while passing to a http restlet service

    - by satish-gunuputi
    Hi , I have a perl client which is calling a http restlet service (put method). Some of the parameters in this call contain japanese text. when I printed the contents of these request parameters in the restlet service I found these chars garbled ! This is my PERL client code: my %request_headers = ( 'DocumentName' => $document_name, --> This name is a JAPANESE String 'DocumentDescription' => 'Test Japanese Chars', 'content-length' => 200, 'Content-Type' => 'application/octet-stream; charset=utf-8', 'User-Agent' => "JPCharTester", ); $s-write_request('PUT', '/test-document/TEST/TEST_DOCUMENT' , %request_headers, $content); in this call both the values of $context and $document_name are JAPANESE Strings. But ONLY the document_name is received as garbled in my backend service. Here goes the Service code: String URL_ENCODING = "UTF-8"; String documentName = requestHeaders.getFirstValue("DocumentName"); System.out.println("Encoded Document Name : "+documentName+" <<<"); --> documentName is garbled here try { documentName = URLDecoder.decode(documentName, URL_ENCODING); System.out.println(>>> Decoded Document Name : "+documentName+" <<<"); --> documentName is garbled here } catch (java.io.UnsupportedEncodingException ex) { throwException(ex.getMessage(), Status.SERVER_ERROR_INTERNAL, ex); } both the above log statements printed GARBLED TEXT !! Can someone tell me what is the mistake I am doing and how to fix this ? Thanks in advance for your help. Regards, Satish.

  • Designing a software based load balancer

    - by Kishore pandey
    Hello to all Server fault users, I am new to this website but have constantly been using the mother website, stackover flow. Well to begin with, i would like to design a load balancer for the organization i am working for. As i am very new to this whole, idea about load balancing and networks. I am finding it very difficult to start my project. I did a lot of research on already existing load balancer and found some(HAPROXY,NGINX) that could solve my problems, but the point is, I am still in a dilemma if they could answer the following requirements of mine: The client and server in my architecture are distributed. The load balancer should take care of the firewall. LB server should balance the load among all servers present in WWW cloud. The LB server should have some sort of configuration file, with the help of which it is possible to configure the servers. Heart beat: With the help of which it would be possible to check if any server is down, if any server is down the request should be passed to some other server. Various load balancing algorithms of the incoming requests. Easy error handling. It should be fairly possible to prioritize the incoming requests. Is there any already available load balncer solution on the market that could satisfy these requirements? If not is there any base code available with the help of which i could develop my own load balncer. If not where should i start from scratch? I am practically new to everything. Any help from a load balancer expert is very much appreciated. Thanx a ton in advance. Cheers and regards. Kishore

  • using iphone to control mac

    - by Ajay Pandey
    i want to use iPhone touch screen as the touchPad for my mac while both devices are connected via bluetooth. So far i hv gone for two approaches what i want is an application which when launched turns the bluetooth on and get connected to mac.Further ...screen of iPhone becomes the touch pad for mac. i dont want to install anything at the mac like any server........ I have already tried the vnc and remotePad approach. the one with vnc looks more promising for me..but even in that case i have to install a vnc server on mac ,i guess and then we'll have to actually call vnc client while my application is still running,which does not look real in 3.2 verson as it does not support multi tasking. Is there any other way of doing it? or is there anything wrong in my above interpretation? please let me know if there is anyother approach of doing the same or if i can do any thing different with my current approach. hoping for quick response Thanks

  • Hosting multiple sites on a single webapp in tomcat

    - by satish
    Scenario: I have a website - www.mydomain.com. Registered users will be given the choice of getting a permanent url to their account on mydomain.com as a subdomain like (username.mydomain.com) or they can opt to have their own domain like www.userdomain.com. So the user can access his/her account through the subdomain URL or their own hostname and the request should be forwarded to a specific url on mydomain.com. For example: xyz.mydomain.com or www.xyz.com should give the user account from www.mydomain.com/webapp/account?id=xyz. The user should be completely unaware about where the content is coming from. Setup: My website is running as a webapp in tomcat 5.5.28 with apache as the web server. I am using a VPS which means I have control over all the configuration files (apache, tomcat and dns server). Can you tell me what are the configurations needed to achieve the above scenario??

  • How to Setup Sharepoint Extranet to authenticate against a dmz AD

    - by Satish
    I have a web app which is extended to extranet for our clients to access. We have setup a different AD server and domain for dmz and clients have to be authenticated against that domain. I'm little confused about the setup especially what all web.config files I have to update. Do I have to update the web.config file for Central admin site and the extended web app. According to this blog I need to do update both, but as soon as I make the changes in the web.config for central admin, central admin site stops working. Here is what I added to the central admin web.config file between /Sharepoint and system.web I have this <connectionStrings> <add name="DMZConnectionString" connectionString= "LDAP://dmz.xxx.com:389/OU=Clients,DC=dmz,DC=xxx,DC=com "/> Between system.web and securityPolicy <membership defaultProvider=”DMZADProvider“> <providers> <add name="DMZADProvider" connectionStringName="DMZConnectionString" connectionUsername="DMZ\ldapUser" connectionPassword="Password" enableSearchMethods="true" attributeMapUsername="userPrincipalName" type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> </providers> </membership> I know the connectionusername and password works becuase I use the same in SSP for importing profiles. Any idea what might be causing the error?

  • how to convert string to double with proper cultureinfo

    - by Vinay Pandey
    Hi All, I have two nvarchar fields in database to store the DataType and DefaultValue, I have a DataType Double and value as 65.89875 in english format. Now I want the user to see the value as per the selected browser language format (65.89875 in English should be displayed as 65,89875 in german). Now if the user edits from german format to 65,89875 which is 65.89875 equivalent in english, and the other user views from english browser it comes as 6589875. This happens because in DB it was stored as 65,89875 and when converted using english culture it becomes 6589875 since it considers , as seperator. Any Idea how I get this working for all the browsers?
