• Annotation based view mapping

  - by Eqbal

  I am trying to get my head around annotation based mappings and I am having some trouble mapping requests directly to jsp. Do all request have to go through a controller? Is it possible to make it just go to a jsp without declaring a RequestMapping for GET? I am using a InternalResourceViewResolver. Below is my app-servlet.xml <context:annotation-config/> <context:component-scan base-package="com.pioneer.b2broe.web" /> <mvc:annotation-driven /> <mvc:view-controller path="/" view-name="home"/> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp/" p:viewClass="org.springframework.web.servlet.view.JstlView" p:suffix=".jsp" p:order="2"/>

• WCF - (Custom) binary serialisation.

  - by Barguast

  I want to be able to query my database over the web, and I am wanting to use a WCF service to handle the requests and results. The problem is that due to the amount of data that can potentially be returned from these queries, I'm worried about how these results will be serialised over the network. For example, I can imagine the XML serialisation looking like: <Results> <Person Name="Adam" DateOfBirth="01/02/1985" /> <Person Name="Bob" DateOfBirth="04/07/1986" /> </Results> And the binary serialisation containing types names and other (unnecessary) metadata. Perhaps even the type name for each element in a collection? o_o Ideally, I'd like to perform the serialisation of certain 'DataContract'-s myself so I can make it super-compact. Does anyone know if this is possible, or of any articles which explain how to do custom serialisation with WCF? Thanks in advance

• Play 2.0 RESTful request post-processing

  - by virtualeyes

  In regard to this question I am curious how one can do post-request REST processing a la (crude): def postProcessor[T](content: T) = { request match { case Accepts.Json() => asJson(content) case Accepts.Xml() => asXml(content) case _ => content } } overriding onRouteRequest in Global config does not appear to provide access to body of the response, so it would seem that Action composition is the way to go to intercept the response and do post-processing task(s). Question: is this a good idea, or is it better to do content-type casting directly within a controller (or other class) method where the type to cast is known? Currently I'm doing this kind of thing everywhere: toJson( i18n("account not found") ) toJson( Map('orderNum-> orderNum) ) while I'd like the toJson/toXml conversion to happen based on accepts header post-request.

• Android Template Application?

  - by stormin986

  I have built an application that I want to use as the foundation for a few other variants. The variants will come from assets / resource files and a unique AndroidManifest.xml. However, I want to be able to leave all the application code alone (modifying the package of all my classes, etc). I'm having a hard time figuring out how to do so. My first thought was to simply have my main application in its own package, and then specify the specific application package in the manifest. However, this gives me issues with the generated R.java class, since it is generated to be in the main application's package. Anyone have any thoughts on how to accomplish this? To have a code baseline, and the application variants happen in resources/assets and the manifest?

• jquery ajax vs browser url

  - by danwoods

  Hello all, I'm trying to use youtube's api to bring back a listing of a user's videos. The request url looks something like: http://gdata.youtube.com/feeds/api/users/username/uploads with 'username' being the correct username. This bring back the appropriate url in the browser. However when I try to access that url via jQuery's $.ajax or $.get functions, using something like: $.ajax({ //set parameters url: "http://gdata.youtube.com/feeds/api/users/username/uploads", type: "GET", //on success success: function (data) { alert("xml successfully captured\n\n" + data); }, //on error error:function (XMLHttpRequest, textStatus, errorThrown, data){ alert(" We're sorry, there seem to be a problem with our connection to youtube.\nYou can access all our videos here: http://www.youtube.com/user/username"); alert(data); } }); $.get("http://gdata.youtube.com/feeds/api/users/username/uploads", function(data){ alert("Data Loaded: " + data); }); I get an empty document returned. Any ideas why this is?

• NHibernate 'IdentifierGenerationException' on an Update trigger

  - by Jan Jongboom

  In my database I have an id column defined as [autonumber] [int] IDENTITY(1,1) NOT NULL which is mapped in my .hbm.xml like: <id name="Id" column="autonumber" type="int"> <generator class="identity" /> </id> When calling session.Save() updates are successful committed to the database. When adding a versioning trigger I however get the error this id generator generates Int64, Int32, Int16 of type IdentifierGenerationException. The trigger is defined as: ALTER TRIGGER [dbo].[CatchUpdates_NVM_FDK_Kenmerken] ON [dbo].[NVM_FDK_Kenmerken] INSTEAD OF UPDATE AS BEGIN SET NOCOUNT ON UPDATE NVM_FDK_Kenmerken SET idIsActive = 0 WHERE internalId IN (SELECT internalId FROM INSERTED) INSERT INTO dbo.NVM_FDK_Kenmerken ( vestigingNummer , internalId , someOtherColumns, dateInserted, idIsActive ) SELECT vestigingNummer, internalId, someOtherColumns, GETDATE(), 1 FROM INSERTED END What am I doing wrong here? When doing manual updates everything works just fine and as expected.

• How to change object positions in an android layout?

  - by Pedro Santos

  Hi, I'm currently working on a very simple aplication, and I intended to make it change the visual aspect depending on the screen size. The application just has 6 buttons like this: http://www.freeimagehosting.net/uploads/e1efb4c4d0.jpg I'm using the AbsoluteLayout, and changing the x and y of the buttons with the methods offsetLeftAndRight and offsetTopAndBottom. I'm not changing the layout of the buttons in the xml file, so the all start in the same place. However, if I use this methods inside the onClickMethod they sometimes appear where I want them, sometimes don't (can't figure out why), but if i use them in the onCreate method, nothing happens. Can someone point me in the right direction? Thanks

• How do I guarante node order for an Xpath 'OR' query

  - by Tom Carter

  I have a snippet of XML that looks like <body> Some text.... <nodeA>....</nodeA> more text <someOtherNode> <nodeA>.......</nodeA> </someOtherNode> <nodeB>.......</nodeB> etc..... </body> I'm selecting all nodeA and NodeB nodes inside <body> using an XPATH query similar to "//nodeA|//nodeB" As I understand it, .NET supports XPATH 1.0 which does not guarantee node order. How can I guarantee selected nodes are returned in document order in my OR query : that's to say : nodeA, nodeA, nodeB

• Microsoft SQL Server 2008 - 99% fragmentation on non-clustered, non-unique index

  - by user550441

  I have a table with several indexes (defined below). One of the indexes (IX_external_guid_3) has 99% fragmentation regardless of rebuilding/reorganizing the index. Anyone have any idea as to what might cause this, or the best way to fix it? We are using Entity Framework 4.0 to query this, the EF queries on the other indexed fields about 10x faster on average then the external_guid_3 field, however an ADO.Net query is roughly the same speed on both (though 2x slower than the EF Query to indexed fields). Table id(PK, int, not null) guid(uniqueidentifier, null, rowguid) external_guid_1(uniqueidentifier, not null) external_guid_2(uniqueidentifier, null) state(varchar(32), null) value(varchar(max), null) infoset(XML(.), null) -- usually 2-4K created_time(datetime, null) updated_time(datetime, null) external_guid_3(uniqueidentifier, not null) FK_id(FK, int, null) locking_guid(uniqueidentifer, null) locked_time(datetime, null) external_guid_4(uniqueidentifier, null) corrected_time(datetime, null) is_add(bit, not null) score(int, null) row_version(timestamp, null) Indexes PK_table(Clustered) IX_created_time(Non-Unique, Non-Clustered) IX_external_guid_1(Non-Unique, Non-Clustered) IX_guid(Non-Unique, Non-Clustered) IX_external_guid_3(Non-Unique, Non-Clustered) IX_state(Non-Unique, Non-Clustered)

• Using Gradle with an existing Android project

  - by Tom Reznik

  I have an existing Android project with the following structure: - ProjectName -- AndroidManifest.xml -- local.properties -- project.properties -- assets -- libs (containing all jars) -- modules (containing all library projects my project depends on) -- res -- src ---- com/namespace/projectname (all my classes including main activity are here) I haven't been using any specific build system to build my project other than the one provided by default with the Android Studio IDE (though the project was originally created with IntelliJ CE. I would like to use Gradle with the android plugin and do some work on my build process. I have tried several configurations in order to achieve this and have failed to complete a successful build every time. What's the recommended approach in this scenario? should I change my project structure? or is it possible to configure gradle using the existing structure? Any help would be greatly appreciated. Thanks!

• What format do I use to store a relatively small amount of user data

  - by wcm

  I am writing a small program for our local high school (pro bono). The program has an interface allows the user to enter school holidays. This is a simple stand alone Windows app. What format should I use to store the data? A big relational data is obviously overkill. My initial plan was to store the data in an XML file. Co-workers have been suggesting that I use JSON files, Access Databases, SQL Lite, and SQL Server Express. There was even a suggestion of old school INI files.

• Unable to view GWT 2.0.1 application in IE8.

  - by shyam.m

  Hi, I'm creating an application using GWT 2.0.1; it complies 6 computations and runs well in all browsers except IE8, it shows a blank page( but can be viewed in IE8 compatibility mode) . When I add the line in my gwt.xml <set-property name="user.agent" value="ie8" / > it compiles just 1 permutation and the application displays fine in IE8. However if I add the line lt;set-property name="user.agent" value="ie8,gecko,gecko1_8,safari,opera" /gt; it compiles all permutations, but the application still cannot be viewed in IE8 but runs properly in all other browsers. Is there any other method to ensure my application will run in all browsers ?

• problem in interceptor executing before action in struts2

  - by vivmal

  Hi All, I am working on struts2. I have an interceptor that executes before my action claas. Now when I submit on a jsp page control goes to interceptor and after some processing there the control goes to action class. This complete flow is running well. But I found two things – 1) Control does not go to action-validation.xml before going to action class. 2) Its not getting the values of textfield or etc that uses has entered into jsp page before submitting. Can anyone tell me how to find solution for these two points. Thanks in advance.

• Solr date field tdate vs date?

  - by user550178

  So I have a question about Solr's field date types which is pretty straight forward: what's the difference between a 'date' field and a 'tdate' one? The schema .xml claims that 'For faster range queries, consider the tdate type' and 'A Trie based date field for faster date range queries and date faceting. ' Fair enough... but what's the precisionStep="6" all about? should i change this? does it change the way i would create the query in case I use the tdate? What's the real advantage or what does Solr do that makes it better? P.S went through google, Solr manual, solr wiki and the java docs without any luck so I'd appreciate a kind and explanatory answer :)... Also checked: http://www.lucidimagination.com/blog/2009/05/13/exploring-lucene-and-solrs-trierange-capabilities/ http://web.archiveorange.com/archive/v/AAfXfqRYyLnDFtskmLRi

• Are entities cached in jpa by default ?

  - by Nitesh Panchal

  Hello, I add entity to my database and it works fine. But when i retrieve the List, i get the old entity, the new entities i add are not shown until i undeploy the application and redeploy it again. This means are my entities cached by default? But, I haven't made any settings for caching entities in my persistence.xml or any such file. I have even tried calling flush(), refresh() and merge(). But still it shows the old entities only. Am i missing something? Please help me.

• GWT and a jaxb objects

  I am trying to use GWT to build objects on the client side that would be sent to a web service elsewhere. These objects are generate through JAX-WS which I am pretty sure uses jaxb to build objects from the xsds that are in the wsdl. Anyhow, GWT was supposed to be able to support this by ignoring annotations or whatever, but it isn't working for me. Here is one of the errors that I am getting: Line 4: The import javax.xml.bind cannot be resolve I am using GWT 2 and the Google plugin for Eclipse.

• Inspecting a Word mail merge data source programmatically

  - by Guy Marom

  I want to iterate over all rows of a MS-Word mail merge data source and extract the relevant data into an XML. I'm currently using this code: Imports Microsoft.Office.Interop Do objXW.WriteStartElement("Recipient") Dim objDataFields As Word.MailMergeDataFields = DataSource.DataFields For Each FieldIndex As Integer In mdictMergeFields.Keys strValue = objDataFields.Item(FieldIndex).Value If Not String.IsNullOrEmpty(strValue) Then strName = mdictMergeFields(FieldIndex) objXW.WriteElementString(strName, strValue) End If Next objXW.WriteEndElement() If DataSource.ActiveRecord = LastRecord Then Exit Do Else DataSource.ActiveRecord = Word.WdMailMergeActiveRecord.wdNextDataSourceRecord End If Loop And it turns out to be a little sluggish (About 1 second for each row). Is there any way to do it faster? My fantasy is finding a function like MailMergeDataSource.ToDatatable and then inspecting the datatable.

• NHibernate and hbm2dll update attribute

  - by michael lucas

  Hi, i'm using NHibernate with Sdf database. In my hibernate.cfg.xml file i've set: <property name="hbm2ddl.auto" value="update"/> But this does not seem to work at all. "Update" attribute should make NHibernate generate missing tables and columns during application launch, but it does not happen. If i want missing tables geenrated I have to set hbm2dll.auto property to "create" which is not an option for me since it drops existing db content beforehand. I experienced the same problem with PostgreSql problem. Am I missing something?

• How do you handle passwords or credentials for standalone applications?

  - by Abel Morelos

  Let's say that you have a standalone application (a Java application in my case) and that this application has a configuration file (a XML file in my case) where you store the credentials (user and password) for a bunch of databases you need to connect. Everything works great, but now you discover (or your are given a new requirement like me) that you have to put this application in a different server and that you can't have these credentials in the configuration files because of security and/or compliance considerations. I'm considering to use data sources hosted in the application server (a WAS server), but I think this could have poor performance and maybe it's not the best approach since I'm connecting from a standalone application. I was also considering to use some sort of encryption, but I would like to keep things as simple as possible. How would you handle this case? Where would you put these credentials or protect them from being compromised? Or how would you connect to your databases in this scenario?

• long processes php

  hi, i need to run a really long php script (four and half, five hours). the script sometimes runs successfully, but sometimes gets killed inexplicably (poss something to do with the shared hosting??). i think that the solution maybe to run the script is smaller chunks. in order to do this i have written a script that stores it's status & position in an xml file, and executes one chunk of the script, before moving the position on. i am having problems hooking up the last bit of the script, which should end the current process & re-execute the script. or maybe i am barking up the wrong tree completely! i have read through what i can find on SO and elsewhere but i'm still none the wiser :( please help!!! dan

• how to import other schema jars when using the scomp tool

  - by MikeJiang

  there is a huge amount of xml schemas for the business, some of them are common types like Money.xsd, Address.xsd, etc, while others are business specific like Customer.xsd, ShippingOrder.xsd, etc. So I decide to compile these schemas into 2 jars, one is commonbeans.jar, the other is businessbeans.jar. I've separated them into different folders. to build the commonbeans.jar is simple, just run "scomp -out commonbeans.jar ....\common*.xsd"; while run "scomp -out businessbeans.jar ....\business*.xsd" is a different story, there are errors say can't find those common types, and run "scomp -out businessbeans.jar ....\business*.xsd ....\business*.xsd" will blindly duplicate all the common types into the businessbeans.jar. so is there any way to link the commonbeans.jar when compile those busimess schemas, maybe something like "scomp -out businessbeans.jar ....\business*.xsd commonbeans.jar". I hope my poor english has expressed my issue!
