• Libraries for developing NCPDP SCRIPT based systems (a standard for e-prescribing)

  - by Kaveh Shahbazian

  What are (based on experiences) best (commercial or open source) libraries for developing NCPDP-based systems? Background: NCPDP (National Council for Prescription Drug Programs) is a not-for-profit, ANSI-accredited, standards development organization. One of it's standards is the SCRIPT Standard for Electronic Prescribing, which allows PHARMACY, PRESCRIBER (i.e. Physician) and PAYERS (patient or more often insurer) communicate. So the SCRIPT standard is about data transmission. Problem: One step in implementing such systems is to develop models for data based on SCRIPT standard. These models should have utilities for serializing/deserializing to/from SCRIPT binary format and SCRIPT XML format (there are two distinct formats here; both must be supported). Here rises the problem (for me at least). To develop this subsystem for handling the model, implementing serializing and deserializing facilities and keep it uptodate with the SCRIPT standard specifications is a lot of work; it needs it's own team and team management issues (to support a standard implementation). So I am looking for a solution to this problem; to keep standard implementation out of the way and focusing on main problems. Thanks to all (Thankyou Freiheit for your hints!) Edit 2: Thanks to all for help! NCPDP (National Council for Prescription Drug Programs) is an standard for e-prescribing. It defines two formats for message transmission: binary and XML. Implementing XML is somehow easier because it is a standard format which in turn gives us more tooling options. The binary format has a very big specification and time-consuming to implement. I did not find an open source solution to work with. So I am looking for commercial alternatives. Edit 1: Please guide me; what's wrong with this question?

• How to: Searchlogic and Tags

  - by bob

  I have installed searchlogic and added will_paginate etc. I currently have a product model that has tagging enabled using the acts_as_taggable_on plugin. I want to search the tags using searchlogic. Here is the taggable plugin page: http://github.com/mbleigh/acts-as-taggable-on Each product has a "tag_list" that i can access using Product.tag_list or i can access a specific tag using Product.tags[0] I can't find the scope to use for searching however with search logic. Here is my part of my working form. <p> <%= f.label :name_or_description_like, "Name" %><br /> <%= f.text_field :name_or_description_like %> </p> I have tried :name_or_description_or_tagged_with_like and :name_or_description_or_tags_like and also :name_or_description_or_tags_list_like to try and get it to work but I keep have an error that says the options i have tried are not found (named scopes not found). I am wondering how I can get this working or how to create my own named_scope that would allow me to search the tags added to each product by the taggable plugin. Thanks!

• protobuf-net v2 alpha - problems with Dictionary<string,string>?

  - by Steve

  I was using a version of v2 of protobuf-net from a few weeks ago quite successfully. (I want to use V2 due to the speed of the pre-compiled serializer running on the Compact Framework.) Everything worked great until I tried to serialize an object with a property of type Dictionary. I received the following error: {"No serializer defined for type: System.Collections.Generic.KeyValuePair`2[[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]"} It looked like there were recent changes made to improve Dictionary support, so I grabbed the latest code from today. After building the CF3.5 and FF3.5 dlls, I tried again. Now I get a different error "The model cannot be changed once frozen." If I remove the ProtoMember attribute from the Dictionary property all seems to work well. Has anyone succcessfully used a Dictionary in v2 of protobuf-net? Is this still too early of a release to be using? My speed tests showed v2 being twice as fast, does that seem accurate (validating my desire to use the less stable v2 pre-alpha bits.)

• ETL , Esper or Drools?

  - by geoaxis

  Hello, The question environment relates to JavaEE, Spring I am developing a system which can start and stop arbitrary TCP (or other) listeners for incoming messages. There could be a need to authenticate these messages. These messages need to be parsed and stored in some other entities. These entities model which fields they store. So for example if I have property1 that can have two text fields FillLevel1 and FillLevel2, I could receive messages on TCP which have both fill levels specified in text as F1=100;F2=90 Later I could add another filed say FillLevel3 when I start receiving messages F1=xx;F2=xx;F3=xx. But this is a conscious decision on the part of system modeler. My question is what do you think is better to use for parsing and storing the message. ETL (using Pantaho, which is used in other system) where you store the raw message and use task executor to consume them one by one and store the transformed messages as per your rules. One could use Espr or Drools to do the same thing , storing rules and executing them with timer, but I am not sure how dynamic you could get with making rules (they have to be made by end user in a running system and preferably in most user friendly way, ie no scripts or code, only GUI) The end user should be capable of changing the parse rules. It is also possible that end user might want to change the archived data as well (for example in the above example if a new value of FillLevel is added, one would like to put a FillLevel=-99 in the previous values to make the data consistent). Please ask for explanations, I have the feeling that I need to revise this question a bit. Thanks

• DDD: Persisting aggregates

  - by Mosh

  Hello, Let's consider the typical Order and OrderItem example. Assuming that OrderItem is part of the Order Aggregate, it an only be added via Order. So, to add a new OrderItem to an Order, we have to load the entire Aggregate via Repository, add a new item to the Order object and persist the entire Aggregate again. This seems to have a lot of overhead. What if our Order has 10 OrderItems? This way, just to add a new OrderItem, not only do we have to read 10 OrderItems, but we should also re-insert all these 10 OrderItems again. (This is the approach that Jimmy Nillson has taken in his DDD book. Everytime he wants to persists an Aggregate, he clears all the child objects, and then re-inserts them again. This can cause other issues as the ID of the children are changed everytime because of the IDENTITY column in database.) I know some people may suggest to apply Unit of Work pattern at the Aggregate Root so it keeps track of what has been changed and only commit those changes. But this violates Persistence Ignorance (PI) principle because persistence logic is leaking into the Domain Model. Has anyone thought about this before? Mosh

• Are there any ASP.NET MVC subscription-based starter kits or examples?

  - by Wayne M

  Basically something that handles the low-level "plumbing" code for a subscription-based service. I see a lot of things dealing with basic membership, but nothing that handles the subscription aspect (recurring billing, automated jobs for setting up billing, notification for billing, etc). This might be the one thing that keeps me from using ASP.NET MVC for my SaaS idea, since it would take a fair amount of development time to write my own; if I go with my other option, Ruby on Rails, I can buy a kit that does all of this for $250. I haven't found anything even remotely close to this for .NET - all of the SaaS sample apps I've seen are more like StackOverflow et all where you have one site that multiple people log on to, not the web application model where you have subscribers who are billed monthly, each of whom has users and other entities (e.g. Customers, Tasks, etc) for their own site. Is there anything similar for ASP.NET, or some kind of guidelines for writing my own if I have to, so I don't waste too much time? As a startup that means that I'm doing all the coding myself. I've found this, but it seems to only be for billing and didn't seem to have much (any?) documentation on exactly how to set it up.

• Jquery datatable Hidden column showing after calling another script .how can i hide the column specified permanently?

  - by Sreenath Plakkat

  My table is <table id="EmployeesTable" style="width: 100%;" class="grid-table06 border-one"> <thead> <tr> <th width="80%" align="left" valign="middle">Name</th> <th width="20%" align="left" valign="middle">Department</th> <th>Id</th> </tr> </thead> </table> My script as follows $(function () { $(".switchDate").click(function () { var id = $(this).attr("rel"); fetchEmployeedetails(id); }); fetchEmployeedetails(@model.Id); //on load function fetchEmployeedetails(id) { $("#EmployeesTable").dataTable({ "bProcessing": true, "bServerSide": true, "sAjaxSource": "/Employees/FetchDetails?Deptid=" + id + "&thresholdLow=4&threshold=100", "sPaginationType": "full_numbers", "bDestroy": true, "aaSorting": [[1, 'desc']], "asStripClasses": ['color01', 'color03'], "aoColumnDefs": [{ "aTargets": [2], "bVisible": false }, { "aTargets": [1], "fnRender": function (oObj) { return "<a href='#showemployees' rel='" + oObj.aData[2] + "'></a>"; } }] }); } }); On load it works fine not showing the hidden "Id" column but in case when I choose the id by switchDate on click function it causes the hidden column to be visible for second. How can I hide the column permanently?

• Programatic re-evalutation of MVVM command's "can execute" state

  - by dzs

  Hello! I'm writing a WPF application using the MVVM pattern, based on the following article: WPF Apps With The Model-View-ViewModel Design Pattern I have two buttons on my View with the buttons' "Command" property bound (with data binding) to a given instance of the RelayCommand class (see "Figure 3 The RelayCommand Class" from the article above). The RelayCommand class has support for checking whether the given command can be executed. WPF automatically disables buttons whose command cannot be executed. Each of my commands (in the ViewModel class) start a background operation, and the command cannot be executed again until the background operation is finished. The RelayCommand instances have information whether the background operation is still working or it is finished. My problem is the following: after pressing the any of the buttons, the buttons automaticaly go disabled (which is OK) because the background operation started and the command cannot be executed until it is finished, but after the operation had finished, the buttons don't go enabled automatically because their command's "can be executed" predicate is not automatically reevaluated. The reevaluation can be manually triggered by having the application loose and regain focus (by pressing ALT+TAB). After doing this trick, the buttons get enabled once again. How can I programatically reevaluate the buttons' command's "can execute" state?

• TFS and Forms Authentication

  - by George

  I don't know squat about TFS, other than as a user who has performed simple check in/outs. I just installed it locally and would like to do joint development with a friend. I was having trouble making my TFS web site on port 8080 visible (the whole scoop is here if your interested) and I wonder if it could be related to the fact that TFS is probably using Windows Authentication to identify the user. Can TFS be set up to use forms authentication? We probably need to set up a VPN, though that's a learning curve too. To use TFS, do our machines have to belong to a domain? We're not admin types, though he is better than me, though I would be interested in any feedback or advice on which path is likely to pan out the best. I already got AxoSoft OneTime working in this type of an environment and it suits us well, but I am tempted at all the bells & whistles with TFS and the ability to tie tracked bug items to code changes. As far as finding a good way to share code, do sites like SourceForge allow one to keep code secure among members only?

• How can i ignore map property in NHibernate with setter

  i need ignore map property with setter in NHibernate, because the relationship between entities is required. this is my simple model public class Person { public virtual Guid PersonId { get; set; } public virtual string FirstName { get; set; } public virtual string SecondName { get; set; } //this is the property that do not want to map public Credential Credential { get; set; } } public class Credential { public string CodeAccess { get; set; } public bool EsPremium { get; set; } } public sealed class PersonMap : ClassMapping<Person> { public PersonMap() { Table("Person"); Cache(x => x.Usage(CacheUsage.ReadWrite)); Id(x => x.Id, m => { m.Generator(Generators.GuidComb); m.Column("PersonId"); }); Property(x => x.FirstName, map => { map.NotNullable(true); map.Length(255); }); Property(x => x.SecondName, map => { map.NotNullable(true); map.Length(255); }); } } I know that if I leave the property Credential {get;} I was not going to take the map of NHibernate, but I need to set the value.

• Calling function using 'new' is less expensive than without it?

  - by Matthew Taylor

  Given this very familiar model of prototypal construction: function Rectangle(w,h) { this.width = w; this.height = h; } Rectangle.prototype.area = function() { return this.width * this.height; }; Can anyone explain why calling "new Rectangle(2,3)" is consistently 10x FASTER than calling "Rectangle(2,3)" without the 'new' keyword? I would have assumed that because new adds more complexity to the execution of a function by getting prototypes involved, it would be slower. Example: var myTime; function startTrack() { myTime = new Date(); } function stopTrack(str) { var diff = new Date().getTime() - myTime.getTime(); println(str + ' time in ms: ' + diff); } function trackFunction(desc, func, times) { var i; if (!times) times = 1; startTrack(); for (i=0; i<times; i++) { func(); } stopTrack('(' + times + ' times) ' + desc); } var TIMES = 1000000; trackFunction('new rect classic', function() { new Rectangle(2,3); }, TIMES); trackFunction('rect classic (without new)', function() { Rectangle(2,3); }, TIMES); Yields (in Chrome): (1000000 times) new rect classic time in ms: 33 (1000000 times) rect classic (without new) time in ms: 368 (1000000 times) new rect classic time in ms: 35 (1000000 times) rect classic (without new) time in ms: 374 (1000000 times) new rect classic time in ms: 31 (1000000 times) rect classic (without new) time in ms: 368

• Why not lump all service classes into a Factory method (instead of injecting interfaces)?

  - by Andrew

  We are building an ASP.NET project, and encapsulating all of our business logic in service classes. Some is in the domain objects, but generally those are rather anemic (due to the ORM we are using, that won't change). To better enable unit testing, we define interfaces for each service and utilize D.I.. E.g. here are a couple of the interfaces: IEmployeeService IDepartmentService IOrderService ... All of the methods in these services are basically groups of tasks, and the classes contain no private member variables (other than references to the dependent services). Before we worried about Unit Testing, we'd just declare all these classes as static and have them call each other directly. Now we'll set up the class like this if the service depends on other services: public EmployeeService : IEmployeeService { private readonly IOrderService _orderSvc; private readonly IDepartmentService _deptSvc; private readonly IEmployeeRepository _empRep; public EmployeeService(IOrderService orderSvc , IDepartmentService deptSvc , IEmployeeRepository empRep) { _orderSvc = orderSvc; _deptSvc = deptSvc; _empRep = empRep; } //methods down here } This really isn't usually a problem, but I wonder why not set up a factory class that we pass around instead? i.e. public ServiceFactory { virtual IEmployeeService GetEmployeeService(); virtual IDepartmentService GetDepartmentService(); virtual IOrderService GetOrderService(); } Then instead of calling: _orderSvc.CalcOrderTotal(orderId) we'd call _svcFactory.GetOrderService.CalcOrderTotal(orderid) What's the downfall of this method? It's still testable, it still allows us to use D.I. (and handle external dependencies like database contexts and e-mail senders via D.I. within and outside the factory), and it eliminates a lot of D.I. setup and consolidates dependencies more. Thanks for your thoughts!

• click event launched only once problem

  - by user281180

  I have a form in which I have many checkboxes. I need to post the data to the controller upon any checkbox checked or unchecked, i.e a click on a checbox must post to the controller, and there is no submit button. What will be the bet method in this case? I have though of Ajax.BeginForm and have the codes below. The problem im having is that the checkbox click event is being detected only once and after that the click event isnt being launched. Why is that so? How can I correct that? <% using (Ajax.BeginForm("Edit", new AjaxOptions { UpdateTargetId = "tests"})) {%> <div id="tests"> <%Html.RenderPartial("Details", Model); %> </div> <input type="submit" value="Save" style="Viibility:hidden" id="myForm"/> <%} %> $(function() { $('input:checkbox').click(function() { $('#myForm').click(); }); });

• Grails - Recursive computing call "StackOverflowError" and don't update on show

  - by Kedare

  Hello, I have a little problem, I have made a Category domain on Grails, but I want to "cache" the string representation on the database by generating it when the representation field is empty or NULL (to avoid recursive queries at each toString), here is the code : package devkedare class Category { String title; String description; String representation; Date dateCreated; Date lastUpdate; Category parent; static constraints = { title(blank:false, nullable:false, size:2..100); description(blank:true, nullable:false); dateCreated(nullable:true); lastUpdate(nullable:true); autoTimestamp: true; } static hasMany = [childs:Category] @Override String toString() { if((!this.representation) || (this.representation == "")) { this.computeRepresentation(true) } return this.representation; } String computeRepresentation(boolean updateChilds) { if(updateChilds) { for(child in this.childs) { child.representation = child.computeRepresentation(true); } } if(this.parent) { this.representation = "${this.parent.computeRepresentation(false)}/${this.title}"; } else { this.representation = this.title } return this.representation; } void beforeUpdate() { this.computeRepresentation(true); } } There is 2 problems : It don't update the representation when the representation if NULL or empty and toString id called, it only update it on save, how to fix that ? On some category, updating it throw a StackOverflowError, here is an example of my actual category table as CSV : Uploaded the csv file here, pasting csv looks buggy: http://kedare.free.fr/Dist/01.csv Updating the representation works everywhere except on "IT" that throw a StackOverlowError (this is the only category that has many childs). Any idea of how can I fix those 2 problems ? Thank you !

• Sending email through a Google Apps account is working locally, but not on my web server...

  - by Janis Baldwin

  Related: Send Email via C# through Google Apps account My question is the same so I implemented Koistya's solution as follows. The heartbreak is that it works beautifully on my dev laptop but when ported to web server it times out with no explanation. My SMTP config is in my web.config file. I made mods based on Koistya's answer: <mailSettings> **Changed** <smtp from="[email protected]"> <network host="smtp.gmail.com" password="[password]" port="587" userName="[email protected]"/> </smtp> **Original** <!--<smtp from="[email protected]"> <network host="mail.domain.com" password="[password]" port="25" userName="[email protected]"/> </smtp>--> </mailSettings> My .Net C# code (before & after removed): SmtpClient mSmtpClient = new SmtpClient(); mSmtpClient.EnableSsl = true; mSmtpClient.Send(message); As I said this works great on my dev environment but not on web. Can anyone help? Thanks.

• Date formats in ActiveRecord / Rails 3

  - by cbmeeks

  In my model, I have a departure_date and a return_date. I am using a text_field instead of the date_select so that I can use the JQuery datepicker. My app is based in the US for now but I do hope to get international members. So basically this is what is happening. The user (US) types in a date such as 04/01/2010 (April 1st). Of course, MySQL stores it as a datetime such as 2010-04-01... Anyway, when the user goes to edit the date later on, it shows "01/04/2010" because I am using a strftime("%m/%d/%Y) which doesn't make sense....so it thinks it is January 4th instead of the original April 1st. It's like the only way to accurately store the data is for the user to type in: 2010-04-01 I hope all of this makes sense. What I am really after is a way for the user to type in (or use the datepicker) a date in their native format. So someone in Europe could type in 01/04/2010 for April 1st but someone in the US would type in 04/01/2010. Is there an easy, elegant solution to this? Thanks for any suggestions.

• MVC design question for forms

  - by kenny99

  Hi, I'm developing an app which has a large amount of related form data to be handled. I'm using a MVC structure and all of the related data is represented in my models, along with the handling of data validation from form submissions. I'm looking for some advice on a good way to approach laying out my controllers - basically I will have a huge form which will be broken down into manageable categories (similar to a credit card app) where the user progresses through each stage/category filling out the answers. All of these form categories are related to the main relation/object, but not to each other. Does it make more sense to have each subform/category as a method in the main controller class (which will make that one controller fairly massive), or would it be better to break each category into a subclass of the main controller? It may be just for neatness that the second approach is better, but I'm struggling to see much of a difference between either creating a new method for each category (which communicates with the model and outputs errors/success) or creating a new controller to handle the same functionality. Thanks in advance for any guidance!

  Hi, I use EF4 and C#. I have a Table in my DataBase (MS SQL 2008) with a default value for a column SYSUTCDATETIME (). The Idea is to automatically add Date and Time as soon as a new record is Created. I create my Conceptual Model using EF4, and I have created an ASP.PAGE with a DetailsView Control in INSERT MODE. My problems: When I create a new Record. EF is not able to insert the actual Date and Time value but it inserts instead this value 0001-01-01 00:00:00.00. I suppose the EF is not able to use SYSUTCDATETIME () defined in my DataBase Any idea how to solve it?

• How do I create and use a junction table in Rails?

  - by Thierry Lam

  I have the following data: A post called Hello has categories greet Another post called Hola has categories greet, international My schema is: create_table "posts", :force => true do |t| t.string "name" t.datetime "created_at" t.datetime "updated_at" end create_table "categories", :force => true do |t| t.string "name" t.datetime "created_at" t.datetime "updated_at" end create_table "posts_categories", :force => true do |t| t.integer "post_id" t.integer "category_id" t.datetime "created_at" t.datetime "updated_at" end After reading the Rails guide, the most suitable relationship for the above seems to be: class Post < ActiveRecord::Base has_and_belongs_to_many :categories end class Category < ActiveRecord::Base has_and_belongs_to_many :posts end My junction table also seems to have a primary key. I think I need to get rid of it. What's the initial migration command to generate a junction table in Rails? What's the best course of action, should I drop posts_categories and re-create it or just drop the primary key column? Does the junction table have a corresponding model? I have used scaffold to generate the junction table code, should I get rid of the extra code? Assuming all the above has been fixed and is working properly, how do I query all posts and display them along with their named categories in the view. For example: Post #1 - hello, categories: greet Post #2 - hola, categories: greet, international

• Problem with JMX query of Coherence node MBeans visible in JConsole

  - by Quinn Taylor

  I'm using JMX to build a custom tool for monitoring remote Coherence clusters at work. I'm able to connect just fine and query MBeans directly, and I've acquired nearly all the information I need. However, I've run into a snag when trying to query MBeans for specific caches within a cluster, which is where I can find stats about total number of gets/puts, average time for each, etc. The MBeans I'm trying to access programatically are visible when I connect to the remote process using JConsole, and have names like this: Coherence:type=Cache,service=SequenceQueue,name=SEQ%GENERATOR,nodeId=1,tier=back It would make it more flexible if I can dynamically grab all type=Cache MBeans for a particular node ID without specifying all the caches. I'm trying to query them like this: QueryExp specifiedNodeId = Query.eq(Query.attr("nodeId"), Query.value(nodeId)); QueryExp typeIsCache = Query.eq(Query.attr("type"), Query.value("Cache")); QueryExp cacheNodes = Query.and(specifiedNodeId, typeIsCache); ObjectName coherence = new ObjectName("Coherence:*"); Set<ObjectName> cacheMBeans = mBeanServer.queryMBeans(coherence, cacheNodes); However, regardless of whether I use queryMBeans() or queryNames(), the query returns a Set containing... ...0 objects if I pass the arguments shown above ...0 objects if I pass null for the first argument ...all MBeans in the Coherence:* domain (112) if I pass null for the second argument ...every single MBean (128) if I pass null for both arguments The first two results are the unexpected ones, and suggest a problem in the QueryExp I'm passing, but I can't figure out what the problem is. I even tried just passing typeIsCache or specifiedNodeId for the second parameter (with either coherence or null as the first parameter) and I always get 0 results. I'm pretty green with JMX — any insight on what the problem is? (FYI, the monitoring tool will be run on Java 5, so things like JMX 2.0 won't help me at this point.)

• Eclipselink update existing tables

  I created a java program for connect the HSQLDB , the first one works well, public final static String DRIVER = "org.hsqldb.jdbcDriver"; public final static String URL = "jdbc:hsqldb:file:F:/hsqlTest/data/db"; public final static String DBNAME = "SA"; but these are not public final static String DRIVER = "org.hsqldb.jdbcDriver"; public final static String URL = "jdbc:hsqldb:file:C:/Program Files/tich Tools/mos tech/app/data/db/t1/t2/01/db"; public final static String DBNAME = "SA"; the error shows like this: java.sql.SQLException: error in script file line: 1 unexpected token: ? at org.hsqldb.jdbc.Util.sqlException(Unknown Source) at org.hsqldb.jdbc.Util.sqlException(Unknown Source) at org.hsqldb.jdbc.JDBCConnection.<init>(Unknown Source) at org.hsqldb.jdbc.JDBCDriver.getConnection(Unknown Source) at org.hsqldb.jdbc.JDBCDriver.connect(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at HSQLDBManagerImp.getconn(HSQLDBManagerImp.java:48) at TESTHSQLDB.main(TESTHSQLDB.java:15) Caused by: org.hsqldb.HsqlException: error in script file line: 1 unexpected token: ? at org.hsqldb.error.Error.error(Unknown Source) at org.hsqldb.scriptio.ScriptReaderText.readDDL(Unknown Source) at org.hsqldb.scriptio.ScriptReaderBase.readAll(Unknown Source) at org.hsqldb.persist.Log.processScript(Unknown Source) at org.hsqldb.persist.Log.open(Unknown Source) at org.hsqldb.persist.Logger.openPersistence(Unknown Source) at org.hsqldb.Database.reopen(Unknown Source) at org.hsqldb.Database.open(Unknown Source) at org.hsqldb.DatabaseManager.getDatabase(Unknown Source) at org.hsqldb.DatabaseManager.newSession(Unknown Source) ... 7 more Caused by: org.hsqldb.HsqlException: unexpected token: ? at org.hsqldb.error.Error.parseError(Unknown Source) at org.hsqldb.ParserBase.unexpectedToken(Unknown Source) at org.hsqldb.ParserCommand.compilePart(Unknown Source) at org.hsqldb.ParserCommand.compileStatement(Unknown Source) at org.hsqldb.Session.compileStatement(Unknown Source) ... 16 more I googled this connection question , but most of them not help much, someone says that may be the HSQLDB version problem. The dbase shut down in "SHUT COMPRESS" model. Anyone give some advice?

• NHibernate.MappingException - Troubles Shooting Checklist (no persister for)

  - by Berryl

  Here's a starter list: 1) if hbm is hand generated, is it an embedded resource? 2) if using FNH, does it pass a PerssistenceSpecification test? 3) if not using FNH, can you save and then load the persisted class? 4) more? I'm sure many of you have gotten this one at one point or another. But have you ever gotten it when you knew your mapping was set up correctly? I started getting this exception after I started using a new repository design, but only in one scenario! PersistenceSpecification tests pass, as do all repository methods (using SQLite). The scenario that leads to the exception is when legacy projects from a different db are converted to green field system. The legacy system is from a different database and has it's own session factory, which should be irrelevant because the error comes after previously unconverted Projects are retrieved and in memory. As the routine tries to save these unconverted Projects into the new database, the exception is thrown, full stack trace below. Any ideas on how to build up the trouble shooting check list and solves this problem? Cheers, Berryl === the Exception trace ===== failed: NHibernate.MappingException : No persister for: Smack.ConstructionAdmin.Domain.Model.Projects.Project at NHibernate.Impl.SessionFactoryImpl.GetEntityPersister(String entityName) at NHibernate.Impl.SessionImpl.GetEntityPersister(String entityName, Object obj) at NHibernate.Engine.ForeignKeys.IsTransient(String entityName, Object entity, Nullable`1 assumed, ISessionImplementor session) at NHibernate.Event.Default.AbstractSaveEventListener.GetEntityState(Object entity, String entityName, EntityEntry entry, ISessionImplementor source) at NHibernate.Event.Default.DefaultSaveOrUpdateEventListener.PerformSaveOrUpdate(SaveOrUpdateEvent event) at NHibernate.Event.Default.DefaultSaveOrUpdateEventListener.OnSaveOrUpdate(SaveOrUpdateEvent event) at NHibernate.Impl.SessionImpl.FireSaveOrUpdate(SaveOrUpdateEvent event) at NHibernate.Impl.SessionImpl.SaveOrUpdate(Object obj) NHibernate\Repository\FabioNHibRepository.cs(46,0): at Smack.Core.Data.NHibernate.Repository.FabioNHibRepository`1.Add(T item) LegacyConversion\LegacyBatchUpdater.cs(20,0): at Smack.ConstructionAdmin.Data.LegacyConversion.LegacyBatchUpdater.ConvertOpenLegacyProjects(ILegacyProjectDao legacyProjectDao, IProjectRepository greenProjectRepository) Data\Brownfield\ProjectBatchUpdate_SQLiteTests.cs(19,0): at Smack.ConstructionAdmin.Tests.Data.Brownfield.ProjectBatchUpdate_SQLiteTests.Test()

• Java Applet not caching

  - by John Fogerty

  Hello world, I'm having a problem with a Java applet I've deployed that is refusing to be cached in the jvm's "sticky" cache (or by the browser). For some reason every time a user loads the page this applet is on, the jvm re-downloads the jar file from the server which causes a long delay. The webpage containing the applet is being accessed via the internet, so according to Sun's Java applet documentation I'm using an <applet> tag rather than an <object> or <embed> tag. Any help debugging or identifying the problem would be much appreciated. Below is the full applet tag I'm using: <applet alt="Scanning Applet failed to load" archive="scanning.jar" code="scanning.scanlet.class" codebase="/java/" codetype="application/java" height="30" mayscript="True" name="scanlet" width="200"> <param name="domain" value="192.168.12.23" /> <param name="publishName" value="scan_attachment" /> <param name="publishURL" value="http://192.168.12.23/draft/update/52" /> <param name="curURL" value="http://192.168.12.23/draft/edit/52" /> Your browser is unable to process the Java &lt;APPLET&gt; tag needed to display this applet <br /> One solution would be to download a better web browser like <a href="http://www.mozilla.com/firefox">Mozilla's Firefox</a> </applet>
