  - by GigaPr

  Hi, i have been using the spring mvc frameworks lately for a university project. Could you tell me why this work <FORM METHOD=POST ACTION="SaveName.jsp"> <input type="image" class="floatR marginTMinus10" src="images/delete.png" name="image" value="${rssItem.id}" alt="Delete"/> </FORM> while this not <input type="image" class="floatR marginTMinus10" src="images/delete.png" name="image" value="${rssItem.id}" alt="Delete"/> does it mean a button has to be in a form to work? Can i use a button? if yes how do i handle the event in the controller? thanks

• mounting ext4 fs with block size of 65536

  - by seaquest

  I am doing some benchmarking on EXT4 performance on Compact Flash media. I have created an ext4 fs with block size of 65536. however I can not mount it on ubuntu-10.10-netbook-i386. (it is already mounting ext4 fs with 4096 bytes of block sizes) According to my readings on ext4 it should allow such big block sized fs.

• Classic ASP Site Throwing Date Conversion Error After Moving Servers?

  - by leen3o

  I am moving an old store from a Win2003 IIS6 server to a Win2008 IIS7 server, moved everything across including database. The front end seems to work just fine, but when I login it has to do pull in data based on date ranges and now from no where I am getting this error? The conversion of a varchar data type to a datetime data type resulted in an out-of-range value Any ideas why this would do this on the new server and NOT on the old one? No code has changed and the DB is a backup of the one from the old server??

• Is do-notation specific to "base:GHC.Base.Monad"?

  - by yairchu

  The idea that the standard Monad class is flawed and that it should actually extend Functor or Pointed is floating around. I'm not necessarily claiming that it is the right thing to do, but suppose that one was trying to do it: import Prelude hiding (Monad(..)) class Functor m => Monad m where return :: a -> m a join :: m (m a) -> m a join = (>>= id) (>>=) :: m a -> (a -> m b) -> m b a >>= t = join (fmap t a) (>>) :: m a -> m b -> m b a >> b = a >>= const b So far so good, but then when trying to use do-notation: whileM :: Monad m => m Bool -> m () whileM iteration = do done <- iteration if done then return () else whileM iteration The compiler complains: Could not deduce (base:GHC.Base.Monad m) from the context (Monad m) Question: Does do-notation work only for base:GHC.Base.Monad? Is there a way to make it work with an alternative Monad class? Extra context: What I really want to do is replace base:Control.Arrow.Arrow with a "generalized" Arrow class: {-# LANGUAGE TypeFamilies #-} class Category a => Arrow a where type Pair a :: * -> * -> * arr :: (b -> c) -> a b c first :: a b c -> a (Pair a b d) (Pair a c d) second :: a b c -> a (Pair a d b) (Pair a d c) (***) :: a b c -> a b' c' -> a (Pair a b b') (Pair a c c') (&&&) :: a b c -> a b c' -> a b (Pair a c c') And then use the Arrow's proc-notation with my Arrow class, but that fails like in the example above of do-notation and Monad. I'll use mostly Either as my pair type constructor and not the (,) type constructor as with the current Arrow class. This might allow to make the code of my toy RTS game (cabal install DefendTheKind) much prettier.

• C# Lists, Foreach, and Types

  - by user406470

  I was wondering if there is a version of foreach that checks only for a specific type and returns it. For example consider this class tree: org.clixel.ClxBasic - org.clixel.ClxObject - org.clixel.ClxSprite - WindowsGame1.test Then consider this code public List<ClxBasic> objects = new List<ClxBasic>(); foreach(GroupTester tester in objects) { tester.GroupTesterOnlyProperty = true; } tester.GroupTesterOnlyProperty is a property created in GroupTester. Is there some way to make something like this work, like an overload of foreach, or another snippet that might help me? I want to make it easy for a programmer to sort through the lists grabbing only what type they need.

• Use a stylesheet when NOT IE

  - by Sam Gregory

  When i use this code <!--[if IE 6]> <link rel="stylesheet" href="ie6.css" type="text/css" /> <![endif]--> <!--[if !IE]> <link rel="stylesheet" href="not_ie.css" type="text/css" /> <![endif]--> IE 6 does correctly use the specified stylesheet but all other browsers ignore both when they should be using the one that basically states, use this stylesheet if you are not IE. Any ideas?

• Applying a function to an arbitrarily long list of arguments

  - by alphomega

  I want to create a function apply that takes a function with an arbitrary amount of arguments as well as a list of integers, and returns the result of the function (Where each integer in the list is an argument in order. I was thinking something like: apply :: ([Int] -> Int) -> [Int] -> Int apply f x:xs = apply (f x) xs apply f [] = f But I know this won't work because the type signature is wrong - the function doesn't take a list of ints, it just takes some amount of int arguments. Additionally, when I get to the base case the f argument to apply should actually be an integer, violating the type signature anyway. Does anyone know how to deal with this sort of problem?

• Mapping one to one foreign key relationships in Entity Framework 4.0?

  - by John K.

  Hello all, I'm sure I'm missing something very simple, but let's say I have two entities, Employee and EmployeeType. Employee type would contain values like 'Full time', 'Contractor', 'Intern', etc. An Employee entity would contain one, and only one EmployeeType value. So I am designing a new .edmx model using the Model-First approach and generating my actual sql server data schema from the model. I want to add an integer type foreign key id into my Employee entity, EmployeeTypeId, which will map to the primary key of the EmployeeType entity. So I've gone ahead and done that in my Employee entity. Where I'm stuck is how, though the Entity Framework designer, to enforce the 1:1 referential constraint on that EmployeeTypeId property? Or does the EF handle that automatically behind the scenes? thanks in advance, John

• Can't add domain users to Reporting Services 2008

  - by Jeremy

  I have SSRS 2008 setup on the database server. The server is part of the domain. Reporting Services is running under NetworkService. When I try to add a domain user using the web interface (Site Settings -- Security -- New Role Assignment), the page posts back but the user is not in the list. The server's log file contains the following Unhandled Exception: ui!ReportManager_0-1!954!01/12/2009-10:14:52:: Unhandled exception: System.Security.Principal.IdentityNotMappedException: Some or all identity references could not be translated. at System.Security.Principal.SecurityIdentifier.Translate(IdentityReferenceCollection sourceSids, Type targetType, Boolean forceSuccess) at System.Security.Principal.SecurityIdentifier.Translate(Type targetType) at System.Security.Principal.WindowsIdentity.GetName() at System.Security.Principal.WindowsIdentity.get_Name() at ReportingServicesHttpRuntime.RsWorkerRequest.GetServerVariable(String name) at System.Web.Security.WindowsAuthenticationModule.OnEnter(Object source, EventArgs eventArgs) at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) Any one have an idea on how to fix this?

• JSF inner datatable not respecting rendered condition of outer table.

  - by Marc

  <h:dataTable cellpadding="0" cellspacing="0" styleClass="list_table" id="OuterItems" value="#{valueList.values}" var="item" border="0"> <h:column rendered="#{item.typeA"> <h:dataTable cellpadding="0" cellspacing="0" styleClass="list_table" id="InnerItems" value="#{item.options}" var="option" border="0"> <h:column > <h:outputText value="Option: #{option.displayValue}"/> </h:column> </h:dataTable> </h:column> <h:column rendered="#{item.typeB"> <h:dataTable cellpadding="0" cellspacing="0" styleClass="list_table" id="InnerItems" value="#{item.demands}" var="demand" border="0"> <h:column > <h:outputText value="Demand: #{demand.displayValue}"/> </h:column> </h:dataTable> </h:column> </h:dataTable> public class Item{ ... public boolean isTypeA(){ return this instanceof TypeA; } public boolean isTypeB(){ return this instanceof TypeB; } ... } public class typeA extends Item(){ ... public List getOptions(){ .... } ... } public class typeB extends Item(){ ... public List getDemands(){ ... } .... } I'm having an issue with JSF. I've abstracted the problem out here, and I'm hoping someone can help me understand how what I'm doing fails. I'm looping over a list of Items. These Items are actually instances of the subclasses TypeA and TypeB. For Type A, I want to display the options, for Type B I want to display the demands. When rendering the page for the first time, this works fine. However, when I post back to the page for some action, I get an error: [3/26/10 12:52:32:781 EST] 0000008c SystemErr R javax.faces.FacesException: Error getting property 'options' from bean of type TypeB at com.sun.faces.lifecycle.ApplyRequestValuesPhase.execute(ApplyRequestValuesPhase.java:89) at com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java(Compiled Code)) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:91) at com.ibm.faces.portlet.FacesPortlet.processAction(FacesPortlet.java:193) My grasp on the JSF lifecyle is very rough. At this point, i understand there is an error in the ApplyRequestValues Phases which is very early and so the previous state is restored and nothing changes. What I don't understand is that in order to fufill the condition for rendering "item.typeA" that object has to be an instance of TypeA. But here, it looks like that object passed the condition even though it was an instance of TypeB. It is like it is evaluating the inner dataTable (InnerItems) before evaluating the outer (outerItems). My working assumption is that I just don't understand how/when the rendered attribute is actually evaluated.

• Stuck on conditionally enable or disable input with JQuery

• JAVA-how to manually compose a MIME multipart message

  - by Augusto Picciani

  I need to compose manually a MIME multipart message. I don't need to use any library to doing it. I'm trying this without success: out.println("From:myemail@mydomain"); out.flush(); out.println("To:myemail@mydomain"); out.flush(); out.println("Date:Thu, 25 Nov 2011 01:00:50 +0100"); out.flush(); out.println("Subject:manual test 269"); out.flush(); out.println("MIME-version:1.0"); out.flush(); out.print("Content-Type: multipart/mixed; boundary=\"1234567\"\n\n"); out.println("--1234567"); out.flush(); out.println("Content-Type: text/plain; charset:utf-8"); out.flush(); out.print("Content-Transfer-Encoding: 7bit\n\n"); out.flush(); out.print("test message\n\n"); out.flush(); out.println("--1234567"); out.flush(); out.println("Content-Type: text/html; charset:utf-8"); out.flush(); out.print("Content-Transfer-Encoding: 7bit\n\n"); out.flush(); out.print("<p><strong>test message in html</strong></p>\n\n"); out.flush(); out.println("--1234567--"); out.flush(); out.print("\r\n.\r\n"); out.flush(); Problem is that my mail client see the headers (from,subject,date,ecc.) but it doesn't see the message body. If i try without multipart it works fine. Maybe problem is in whitespaces character.

• SQL conditional Pivot

  - by Coov

  Yes, this is another Pivot question... I've read through nearly all the previous questions and I can't seem to hack together a query that does what I need. Here is what my table looks like: FirmName Account Balance Pmt Revolving Installment Mortgage Amex 12345 10000 2000 1 0 0 Discover 54321 20000 4000 1 0 0 Chase 13579 100000 1500 0 0 1 Wells Fargo 2468 40000 900 0 1 0 The last three bit columns (Revolving, Installment, & Mortgage) dictate how the columns should be rolled up into a type. Each result requires three columns based on the type and its row count. The outcome should be one row with many columns. Here is what the result should look like: Revolving1_Firm Revolving1_Balance Revolving1_Pmt Revolving2_Firm Revolving2_Balance Revolving2_Pmt Realestate1_Firm Realestate1_Balance Realestate1_Pmt Vehicle1_Firm Vehicle1_Balance Vehicle1_Pmt Amex 10000 2000 Discover 20000 4000 Chase 100000 1500 Wells Fargo 40000 900 How do you pivot based on the bit fields (Revolving, Installment, & Mortgage) and retain the proper count so that that each column gets count # appended to it?

• java.util.Date.toString() is printing out wrong format

  - by pacoverflow

  The following code prints out "vmtDataOrig.creationdate=2012-11-03" VmtData vmtDataOrig = VmtDataDao.getInstance().loadVmt(1); System.out.println("vmtDataOrig.creationdate=" + vmtDataOrig.getCreationDate().toString()); Here is the definition of the creationDate field in the VmtData class: private Date creationDate = null; Here is the hibernate mapping of the creationDate field to the database table column: <property name="creationDate" column="CREATIONDATE" type="date"/> The CREATIONDATE column in the MySQL database table is of type "date", and for the record retrieved it has the value "2012-11-03". The Javadoc for the java.util.Date.toString() method says it is supposed to print the Date object in the form "dow mon dd hh:mm:ss zzz yyyy". Anyone know why it is printing it out in the form "yyyy-MM-dd"?

• Mixing table per subclass and per hierarchy in hibernate

  - by Xelluloid

  In my database there are two three tables. The first one, table ABSTRACT, holds three columns id, type, someText This table contains all abstract information for the abstract class abstract. Now the two tables CONCRETEONE and CONCRETETWO contain all information for the concrete classes concreteOne and concreteTwo. Now I know I could use the table per subclass strategy from hibernate to create a mapping with inheritance. But as I have a column that marks the type of the concrete implementation could it be possible to create some mixed behaviour like a table per subclass strategy with an discriminator?

• How to remove the explicit dependencies to other projects' libraries in Eclipse launch configuration

  - by euluis

  In Eclipse it is possible to create launch configurations in a project, specifying the runtime dependencies from another project. A problem I found was that if you have a multiple project workspace, being possible that each project has its own libraries, it is easy to add explicit dependencies in a secondary project to libraries that are of another project and therefore subject to change. An example of this problem follows: proj1 +-- src +-- lib +-- jar1-v1.0.jar +-- jar2-v1.0.jar proj2 +-- src +-- proj2-tests.launch I don't have a dependency from the code in proj2/src to the libraries in proj1/lib. Nevertheless, I do have a dependency from proj2/src to proj1/src, although since there is an internal dependency in the code in proj1/src to its libraries jar1-v1.0.jar and jar2.v1.0.jar, I have to add a dependency in proj2-tests.launch to the libraries in proj1/lib. This translates to the following ugly lines in proj2-tests.launch: <listEntry value="<?xml version="1.0" encoding="UTF-8" standalone="no"?> <runtimeClasspathEntry path="3" projectName="proj1" type="1"/> "/> <listEntry value="<?xml version="1.0" encoding="UTF-8" standalone="no"?> <runtimeClasspathEntry internalArchive="/proj1/lib/jar1-v1.0.jar" path="3" type="2"/> "/> <listEntry value="<?xml version="1.0" encoding="UTF-8" standalone="no"?> <runtimeClasspathEntry internalArchive="/proj1/lib/jar2-v1.0.jar" path="3" type="2"/> "/> This wouldn't be a big problem if there wasn't the need from time to time to evolve the software, upgrade the libraries and etc. Consider the common need to upgrade the libraries jar1-v1.0.jar and jar2-v1.0.jar to their versions v1.1. Consider that you have about 10 projects in one workspace, having about 5 libraries each and about 4 launch configurations. You get a maintenance overhead in doing a simple upgrade of a library, which normally must imply changes in files for which there wasn't the need for. Or maybe I'm doing something wrong... What I would like to state is proj2 depends on proj1 and on its libraries and having this translated to simply that in the *.launch files. Is that possible?

• IGrouping and Casting in Linq

  - by FiveTools

  I have the following query: var groupCats = from g in groups group g by g.Value into grouped select new { GroupCategory = grouped.Key, Categories = GetCategories(grouped.Key, child) }; This works fine. In the anonymous type returned GroupCategory is a string, and Categories are an Enumerable - what is the proper way to declare this instead of using 'var'? I tried: IGrouping<string,string> groupCats = from g in groups group g by g.Value into grouped select new { GroupCategory = grouped.Key, Categories = GetCategories(grouped.Key, child) }; and IGrouping<string,Enumerable<string>> groupCats = from g in groups group g by g.Value into grouped select new { GroupCategory = grouped.Key, Categories = GetCategories(grouped.Key, child) }; In both instances I get: Cannot implicity convert type....An explicit conversion exists (are you missing a cast) How do I cast this?

• Generics and Exposing .Net Types For COM Consumers?

  - by IbrarMumtaz

  I remember seeing a question on my official MS 70-536 exam that talked about a simple class that was designed to be exposed for COM calling clients and etc. of all the members defined in the classes I chose the answer D. The one that used a generic. My question to you guys is this: If you were designing a .net custom type that was to be eventually consumed by a com caller or a com type .... of all the guidelines I have read on this subject. Generics is the one .Net topic I would not include in a class for this purpose I would omit such a data member or use something else? Am I right in thinking this. As soon as I saw this question I knew it was generics but I can't seem to prove it. Surely I did not make this up ... generics is a .net feature right?
