• getting expat to use .dtd for entity replacement in python

  - by nicolas78

  I'm trying to read in an xml file which looks like this <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE dblp SYSTEM "dblp.dtd"> <dblp> <incollection> <author>Jos&eacute; A. Blakeley</author> </incollection> </dblp> The point that creates the problem looks is the Jos&eacute; A. Blakeley part: The parser calls its character handler twice, once with "Jos", once with " A. Blakeley". Now I understand this may be the correct behaviour if it doesn't know the eacute entity. However, this is defined in the dblp.dtd, which I have. I don't seem to be able to convince expat to use this file, though. All I can say is p = xml.parsers.expat.ParserCreate() # tried with and without following line p.SetParamEntityParsing(xml.parsers.expat.XML_PARAM_ENTITY_PARSING_ALWAYS) p.UseForeignDTD(True) f = open(dblp_file, "r") p.ParseFile(f) but expat still doesn't recognize my entity. Why is there no way to tell expat which DTD to use? I've tried putting the file into the same directory as the XML putting the file into the program's working directory replacing the reference in the xml file by an absolute path What am I missing? Thx.

• Why Illegal cookies are send by Browser and received by web servers (rfc 2109, 2965)?

  - by Artyom

  Hello, According to RFC 2109, 2965 cookie's value can be either HTTP token or quoted string, and token can't include non-ASCII characters. Cookie's RFC 2109 and RFC2965 HTTP's RFC 2068 token definition: http://tools.ietf.org/html/rfc2068#page-16 However I had found that Firefox browser (3.0.6) sends cookies with utf-8 string as-is and three web servers I tested (apache2, lighttpd, nginx) pass this string as-is to the application. For example, raw request from browser: $ nc -l -p 8080 GET /hello HTTP/1.1 Host: localhost:8080 User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.9) Gecko/2009050519 Firefox/2.0.0.13 (Debian-3.0.6-1) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: windows-1255,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Cookie: wikipp=1234; wikipp_username=?????? Cache-Control: max-age=0 And raw response of apache, nginx and lighttpd HTTP_COOKIE CGI variable: wikipp=1234; wikipp_username=?????? What do I miss? Can somebody explain me?

• How do I add and remove an event listener using a function with parameters?

  - by Bungle

  Sorry if this is a common question, but I couldn't find any answers that seemed pertinent through searching. If I attach an event listener like this: window.addEventListener('scroll', function() { check_pos(box); }, false); it doesn't seem to work to try to remove it later, like this: window.removeEventListener('scroll', function() { check_pos(box); }, false); I assume this is because the addEventListener and removeEventListener methods want a reference to the same function, while I've provided them with anonymous functions, which, while identical in code, are not literally the same. How can I change my code to get the call to removeEventListener to work? The "box" argument refers to the name of an <iframe> that I'm tracking on the screen; that is, I want to be able to subscribe to the scroll event once for each <iframe> that I have (the quantity varies), and once the check_pos() function measures a certain position, it will call another function and also remove the event listener to free up system resources. My hunch is that the solution will involve a closure and/or naming the anonymous function, but I'm not sure exactly what that looks like, and would appreciate a concrete example. Hope that makes sense. Thanks for any help!

• PayPal integration woes: PDT hangs on return to site

  - by Tom

  Hi, I'm implementing PayPal IPN & PDT. After some headache & time at the sandbox, IPN is working well and PDT returns the correct $_GET data. The implementation is as follows: Pass user ID in form to PayPal User buys product and triggers IPN which updates database for given user ID PDT returns transaction ID when user returns to site The return page says "please wait" and repeat-Ajax-checks for the transaction status User is redirected to success/failure page Everything works well, EXCEPT that when using the PayPal ready PHP code for PDT to do a return POST, the page hangs. PayPal waits for a response and the user never gets back to my site. I'm not getting a fail status, just nothing. The funny thing is that once the unknown error occurs, my test domain becomes unresponsive for a short period. The code (PHP): https://www.paypal.com/us/cgi-bin/webscr?cmd=p/xcl/rec/pdt-code-outside If I comment out the POST back, it all works fine. I'm able to pin down the problem to once the code enters the while{} loop. Unfortunately, I'm not experienced enough to write a replacement from scratch for the PayPal code, so would really appreciate any ideas on what might be wrong. The POST back goes to ssl://www.sandbox.paypal.com, and I'm using button code and an authorisation token that have all been created via a sandbox test account. Thanks in advance.

• Weird .net 4.0 exception when running unit tests

  - by vdh_ant

  Hi guys I am receiving the following exception when trying to run my unit tests using .net 4.0 under VS2010 with moq 3.1. Attempt by security transparent method 'SPPD.Backend.DataAccess.Test.Specs_for_Core.When_using_base.Can_create_mapper()' to access security critical method 'Microsoft.VisualStudio.TestTools.UnitTesting.Assert.IsNotNull(System.Object)' failed. Assembly 'SPPD.Backend.DataAccess.Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is marked with the AllowPartiallyTrustedCallersAttribute, and uses the level 2 security transparency model. Level 2 transparency causes all methods in AllowPartiallyTrustedCallers assemblies to become security transparent by default, which may be the cause of this exception. The test I am running is really straight forward and looks something like the following: [TestMethod] public void Can_create_mapper() { this.SetupTest(); var mockMapper = new Moq.Mock<IMapper>().Object; this._Resolver.Setup(x => x.Resolve<IMapper>()).Returns(mockMapper).Verifiable(); var testBaseDa = new TestBaseDa(); var result = testBaseDa.TestCreateMapper<IMapper>(); Assert.IsNotNull(result); //<<< THROWS EXCEPTION HERE Assert.AreSame(mockMapper, result); this._Resolver.Verify(); } I have no idea what this means and I have been looking around and have found very little on the topic. The closest reference I have found is this http://dotnetzip.codeplex.com/Thread/View.aspx?ThreadId=80274 but its not very clear on what they did to fix it... Anyone got any ideas?

• Capistrano fails for multiple host deployments

  - by morris082

  I be at a loss here, and after scouring the seas (read: internet) for solutions I am left with none other than to hit up the stack. any help appreciated. I have capistrano running locally for deployments onto several different environments. (I'm on windows 7, fwiw). All was well until I needed to deploy to multiple :app servers during a single deployment. Usually I'm prompted for my ssh passphrase once when I call 'cap deploy'. I have ssh-agent running (git never pesters for my pass) but despite this Capistrano has always bugged me once each deployment. Regardless, it always worked when deploying to ONE host. Now, when I attempt to deploy to multiple servers at once, it asks for my passphrase what appears to be multiple times: (ips removed by ME) servers: ["redacted", "redacted"]<br /> Enter passphrase for ~/.ssh/id_rsa: Enter passphrase for ~/.ssh/id_rsa: So with the above I enter my passphrase but this doesn't work. It waits as little while, then spits out this error: connection failed for: <one of the server ips> (NoMethodError: undefined method `overwrite' for nil:NilClass) And that's the end of that. I can "passwordless" ssh into the servers I'm deploying on just fine. I'm pretty certain the ssh-agent is running since I can hit Git w/out entering my passphrase every time Using 'forward_agent' setting in cap deploy did not work. This is my role: role :app, "ip 1 removed", "ip 2 removed" If i set default_run_options[:max_hosts] = 1, it works OK but it asks for my passphrase for every single connection to each host I'm deploying to.. which ends up being a lot. Essentially I'm looking for any of the below (but not limited to): - "You're never going to fix that on windows" - "This is how you get REAL passwordless deployment in capistrano" - "Have you overlooked this setting/feature?" - "I have a rock that can fix anything, you may borrow it" Thanks!

• Book recommendation for Silverlight

  - by Mathias Weyel

  Hi there, yet another question for recommendations for a book on Silverlight. I look for a book that covers the UI and styling and, if possible, custom drawing and graphics. Very important for me is the style of the book - it should focus on the actual programming and not on where to click in Visual Studio to get things done. Let's take a fictional example for proper usage of the DataGrid control: Bad: To use the data grid, drag it from the toolbox onto the control. You can change the background color by clicking on “Background” in the properties. To define custom columns, click on columns and edit them in the configuration window that opens. Good: To use the DataGrid, you need a reference to the blah dll and declare the namespace in the XAML like this (blah), the data model should be like blah and if you want to define how the columns look like, you need to define them like this (more blah). And if you want to do this in C# because you for whatever reason aren’t able or willing to use XAML, this would look like blah. Bonus points for coverage of topics like how to manage resources (images/fonts) and internationalization. There are quite some snippets on how to do that on the internet but somehow each of them looks like they work but are not a proper way of doing it. cheers Mathias

• database schema eligible for delta synchronization

  - by WilliamLou

  it's a question for discussion only. Right now, I need to re-design a mysql database table. Basically, this table contains all the contract records I synchronized from another database. The contract record can be modified, deleted or users can add new contract records via GUI interface. At this stage, the table structure is exactly the same as the Contract info (column: serial number, expiry date etc.). In that case, I can only synchronize the whole table (delete all old records, replace with new ones). If I want to delta(only synchronize with modified, new, deleted records) synchronize the table, how should I change the database schema? here is the method I come up with, but I need your suggestions because I think it's a common scenario in database applications. 1)introduce a sequence number concept/column: for each sequence, mark the new added records, modified records, deleted records with this sequence number. By recording the last synchronized sequence number, only pass those records with higher sequence number; 2) because deleted contracts can be added back, and the original table has primary key constraints, should I create another table for those deleted records? or add a flag column to indicate if this contract has been deleted? I hope I explain my question clearly. Anyway, if you know any articles or your own suggestions about this, please let me know. Thanks!

• MySQL Query That Can Pull the Data I am Seeking?

  - by Amy

  On the project I am working on, I am stuck with the table structure from Hades. Two things to keep in mind: I can't change the table structure right now. I'm stuck with it for the time being. The queries are dynamically generated and not hard coded. So, while I am asking for a query that can pull this data, what I am really working toward is an algorithm that will generate the query I need. Hopefully, I can explain the problem without making your eyes glaze over and your brain implode. We have an instance table that looks (simplified) along these lines: Instances InstanceID active 1 Y 2 Y 3 Y 4 N 5 Y 6 Y Then, there are multiple data tables along these lines: Table1 InstanceID field1 reference_field2 1 John 5 2 Sally NULL 3 Fred 6 4 Joe NULL Table2 InstanceID field3 5 1 6 1 Table3 InstanceID fieldID field4 5 1 Howard 5 2 James 6 2 Betty Please note that reference_field2 in Table1 contains a reference to another instance. Field3 in Table2 is a bit more complicated. It contains a fieldID for Table 3. What I need is a query that will get me a list as follows: InstanceID field1 field4 1 John Howard 2 Sally 3 Fred The problem is, in the query I currently have, I do not get Fred because there is no entry in Table3 for fieldID 1 and InstanceID 6. So, the very best list I have been able to get thus far is InstanceID field1 field4 1 John Howard 2 Sally In essence, if there is an entry in Table1 for Field 2, and there is not an entry in Table 3 that has the instanceID contained in field2 and the field ID contained in field3, I don't get the data from field1. I have looked at joins till I'm blue in the face, and I can't see a way to handle the case when table3 has no entry.

• Really simple JSON serialization in .NET

  - by Evgeny

  I have some simple .NET objects I'd like to serialize to JSON and back again. The set of objects to be serialized is quite small and I control the implementation, so I don't need a generic solution that will work for everything. Since my assembly will be distributed as a library I'd really like to avoid a dependency on some third-party DLL: I just want to give users one assembly that they can reference. I've read the other questions I could find on converting to and from JSON in .NET. The recommended solution of JSON.NET does work, of course, but it requires distributing an extra DLL. I don't need any of the fancy features of JSON.NET. I just need to handle a simple object (or even dictionary) that contains strings, integers, DateTimes and arrays of strings and bytes. On deserializing I'm happy to get back a dictionary - it doesn't need to create the object again. Is there some really simple code out there that I could compile into my assembly to do this simple job? I've also tried System.Web.Script.Serialization.JavaScriptSerializer, but where it falls down is the byte array: I want to base64-encode it and even registering a converter doesn't let me easily accomplish that due to the way that API works (it doesn't pass in the name of the field).

• Access reading error when using class member variable

  - by bsg

  Hi, I have a class with private member variables declared in a header file. In my constructor, I pass in some filenames and create other objects using those names. This works fine. When I try to add another member variable, however, and initialize it in the constructor, I get an access reading violation. I sent the code to someone else and it works fine on his computer. Any idea what could be wrong? Here is the offending code: The .h file: class QUERYMANAGER { INDEXCACHE *cache; URLTABLE *table; SNIPPET *snip; int* iquery[MAX_QUERY_LENGTH]; int* metapointers[MAX_QUERY_LENGTH]; int blockpointers[MAX_QUERY_LENGTH]; int docpositions[MAX_QUERY_LENGTH]; int numberdocs[MAX_QUERY_LENGTH]; int frequencies[MAX_QUERY_LENGTH]; int docarrays[MAX_QUERY_LENGTH][256]; int qsize; public: QUERYMANAGER(); QUERYMANAGER(char *indexfname, char *btfname, char *urltablefname, char *snippetfname, char *snippetbtfname); ~QUERYMANAGER(); This is the .cpp file: #include "querymanagernew.h" #include "snippet.h" using namespace std; QUERYMANAGER::QUERYMANAGER(char *indexfname, char *btfname, char *urltablefname, char *snippetfname, char *snippetbtfname){ cache = new INDEXCACHE(indexfname, btfname); table = new URLTABLE(urltablefname); snip = new SNIPPET(snippetfname, snippetbtfname); //this is where the error occurs qsize = 0; } I am totally at a loss as to what is causing this - any ideas? Thanks, bsg

• C# How to perform a live xslt transformation on an in memory object?

  - by JL

  I have a function that takes 2 parameters : 1 = XML file, 2 = XSLT file, then performs a transformation and returns the resulting HTML. Here is the function: /// <summary> /// Will apply an XSLT style to any XML file and return the rendered HTML. /// </summary> /// <param name="xmlFileName"> /// The file name of the XML document. /// </param> /// <param name="xslFileName"> /// The file name of the XSL document. /// </param> /// <returns> /// The rendered HTML. /// </returns> public string TransformXml(string xmlFileName, string xslFileName) { var xtr = new XmlTextReader(xmlFileName) { WhitespaceHandling = WhitespaceHandling.None }; var xd = new XmlDocument(); xd.Load(xtr); var xslt = new System.Xml.Xsl.XslCompiledTransform(); xslt.Load(xslFileName); var stm = new MemoryStream(); xslt.Transform(xd, null, stm); stm.Position = 1; var sr = new StreamReader(stm); xtr.Close(); return sr.ReadToEnd(); } I want to change the function not to accept a file for the XML, but instead just an object. The object is exactly compatible with the xslt, if it was serialized to file. But I don't want to have to serialize it to a file first. So to recap : keep the xslt coming from a file, but the xml input should an object I pass and would like to generate the xml from without any file system interaction.

• JDO difficulties in retrieving persistent vector

  - by Michael Omer

  I know there are already some posts regarding this subject, but although I tried using them as a reference, I am still stuck. I have a persistent class as follows: @PersistenceCapable(identityType = IdentityType.APPLICATION) public class GameObject implements IMySerializable{ @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) protected Key m_databaseKey; @NotPersistent private final static int END_GAME_VAR = -1000; @Persistent(defaultFetchGroup = "true") protected GameObjectSet m_set; @Persistent protected int m_databaseType = IDatabaseAccess.TYPE_NONE; where GameObjectSet is: @PersistenceCapable(identityType = IdentityType.APPLICATION) @FetchGroup(name = "mySet", members = {@Persistent(name = "m_set")}) public class GameObjectSet { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key id; @Persistent private Vector<GameObjectSetPair> m_set; and GameObjectSetPair is: @PersistenceCapable(identityType = IdentityType.APPLICATION) public class GameObjectSetPair { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key id; @Persistent private String key; @Persistent(defaultFetchGroup = "true") private GameObjectVar value; When I try to fetch the entire structure by fetching the GameObject, the set doesn't have any elements (they are all null) I tried adding the fetching group to the PM, but to no avail. This is my fetching code Vector<GameObject> ret = new Vector<GameObject>(); PersistenceManager pm = PMF.get().getPersistenceManager(); pm.getFetchPlan().setMaxFetchDepth(-1); pm.getFetchPlan().addGroup("mySet"); Query myQuery = pm.newQuery(GameObject.class); myQuery.setFilter("m_databaseType == objectType"); myQuery.declareParameters("int objectType"); try { List<GameObject> res = (List<GameObject>)myQuery.execute(objectType); ret = new Vector<GameObject>(res); for (int i = 0; i < ret.size(); i++) { ret.elementAt(i).getSet(); ret.elementAt(i).getSet().touchSet(); } } catch (Exception e) { } finally { pm.close(); } Does anyone have any idea? Thanks Mike

• Adding Control to Container Control that is in User Control - How to properly initialize?

  - by DougJones

  Let's say I have a user control MyUserControl, which has a container control (it's a server control, but it could just be a Panel) and a dropdownlist. The dropdownlist is not in the container control initially. In it's code-behind, I am overriding OnInit and creating the user control, which includes populating a dropdownlist and adding that dropdownlist to my container control. I have a public property Year, which is an int. Based on the value of Year, I want to populate the dropdownlist. The problem is that in OnInit, year is always 0. On the page Init, I am setting year, but that doesn't run until AFTER the control's Init runs. If I try to set the value on PreInit on the page, the page hasn't initialized the control and I get invalid null reference when setting a value to the control. My question is: How can I properly initialize the control? How can I set the value on the page, before the control actually gets initialized? If I move the control's code to OnLoad, it'll work until I have to do a postback. In this case I need to, though!

• Issues Deploying ROOT Context in Tomcat6

  - by Josh K

  I'm working on getting an application deployed to the ROOT ("/") context in my Tomcat 6 instance. Here's what has been done: Defined another virtual host (domain.com) Created the respective folder (/etc/tomcat6/Catalina/domain.com) Set it to auto deploy WAR's Set appBase to CATALINA_BASE/domainapps and created respective folder Copied manager.xml from localhost to domain.com. Now I'm trying to deploy into the ROOT context by uploading a ROOT.war to CATALINA_BASE/domainapps. This isn't working. I don't get any exceptions thrown, but the stock ROOT page ("It works !") stays up. I have successfully deployed it into another context (by uploading domainapp.war and viewing at /domainapp), but not ROOT. Re-reading the Virtual Host setup it makes reference to CATALINA_HOME and CATALINA_BASE. My CATALINA_HOME is at /usr/share/tomcat6/domainapp while CATALINA_BASE is /var/lib/tomcat6. Which should I be using for what? Currently haven't touched CATALINA_HOME but will try messing with a few things there. A better question might be what is the generally accepted flow taken to setup a new Tomcat instance and deploy an application to the root context.

• Why does Hibernate ignore the JPA2 standardized properties in my persistence.xml?

  - by Ophidian

  I have an extremely simple web application running in Tomcat using Spring 3.0.1, Hibernate 3.5.1, JPA 2, and Derby. I am defining all of my database connectivity in persistence.xml and merely using Spring for dependency injection. I am using embedded Derby as my database. Everything works correctly when I define the driver and url properties in persistence.xml in the classic Hibernate manner as thus: <property name="hibernate.connection.driver_class" value="org.apache.derby.jdbc.EmbeddedDriver"/> <property name="hibernate.connection.url" value="jdbc:derby:webdb;create=true"/> The problems occur when I switch my configuration to the JPA2 standardized properties as thus: <property name="javax.persistence.jdbc.driver" value="org.apache.derby.jdbc.EmbeddedDriver"/> <property name="javax.persistence.jdbc.url" value="jdbc:derby:webdb;create=true"/> When using the JPA2 property keys, the application bails hard with the following exception: java.lang.UnsupportedOperationException: The user must supply a JDBC connection Does anyone know why this is failing? NOTE: I have copied the javax... property strings straight from the Hibernate reference documentation, so a typo is extremely unlikely.

• Index Tuning for SSIS tasks

  - by Raj More

  I am loading tables in my warehouse using SSIS. Since my SSIS is slow, it seemed like a great idea to build indexes on the tables. There are no primary keys (and therefore, foreign keys), indexes (clustered or otherwise), constraints, on this warehouse. In other words, it is 100% efficiency free. We are going to put indexes based on usage - by analyzing new queries and current query performance. So, instead of doing it our old fashioned sweat and grunt way of actually reading the SQL statements and execution plans, I thought I'd put the shiny new Database Engine Tuning Advisor to use. I turned SQL logging off in my SSIS package and ran a "Tuning" trace, saved it to a table and analyzed the output in the Tuning Advisor. Most of the lookups are done as: exec sp_executesql N'SELECT [Active], [CompanyID], [CompanyName], [CompanyShortName], [CompanyTypeID], [HierarchyNodeID] FROM [dbo].[Company] WHERE ([CompanyID]=@P1) AND ([StartDateTime] IS NOT NULL AND [EndDateTime] IS NULL)',N'@P1 int',1 exec sp_executesql N'SELECT [Active], [CompanyID], [CompanyName], [CompanyShortName], [CompanyTypeID], [HierarchyNodeID] FROM [dbo].[Company] WHERE ([CompanyID]=@P1) AND ([StartDateTime] IS NOT NULL AND [EndDateTime] IS NULL)',N'@P1 int',2 exec sp_executesql N'SELECT [Active], [CompanyID], [CompanyName], [CompanyShortName], [CompanyTypeID], [HierarchyNodeID] FROM [dbo].[Company] WHERE ([CompanyID]=@P1) AND ([StartDateTime] IS NOT NULL AND [EndDateTime] IS NULL)',N'@P1 int',3 exec sp_executesql N'SELECT [Active], [CompanyID], [CompanyName], [CompanyShortName], [CompanyTypeID], [HierarchyNodeID] FROM [dbo].[Company] WHERE ([CompanyID]=@P1) AND ([StartDateTime] IS NOT NULL AND [EndDateTime] IS NULL)',N'@P1 int',4 and when analyzed, these statements have the reason "Event does not reference any tables". Huh? Does it not see the FROM dbo.Company??!! What is going on here? So, I have multiple questions: How do I get it to capture the actual statement executing in my trace, not what was submitted in a batch? Are there any best practices to follow for tuning performance related to SSIS packages running against SQL Server 2008?

• Help understanding .NET delegates, events, and eventhandlers

  - by Seth Spearman

  Hello, In the last couple of days I asked a couple of questions about delegates HERE and HERE. I confess...I don't really understand delegates. And I REALLY REALLY REALLY want to understand and master them. (I can define them--type safe function pointers--but since I have little experience with C type languages it is not really helpful.) Can anyone recommend some online resource(s) that will explain delegates in a way that presumes nothing? This is one of those moments where I suspect that VB actually handicaps me because it does some wiring for me behind the scenes. The ideal resource would just explain what delegates are, without reference to anything else like (events and eventhandlers), would show me how all everything is wired up, explain (as I just learned) that delegates are types and what makes them unique as a type (perhaps using a little ildasm magic)). That foundation would then expand to explain how delegates are related to events and eventhandlers which would need a pretty good explanation in there own right. Finally this resource could tie it all together using real examples and explain what wiring DOES happen automatically by the compiler, how to use them, etc. And, oh yeah, when you should and should not use delegates, in other words, downsides and alternatives to using delegates. What say ye? Can any of you point me to resource(s) that can help me begin my journey to mastery? EDIT One last thing. The ideal resource will explain how you can and cannot use delegates in an interface declaration. That is something that really tripped me up. Thanks for your help. Seth

• Improving field get and set performance with ASM or Javassist

  - by ng

  I would like to avoid reflection in an open source project I am developing. Here I have classes like the following. public class PurchaseOrder { @Property private Customer customer; @Property private String name; } I scan for the @Property annotation to determine what I can set and get from the PurchaseOrder reflectively. There are many such classes all using java.lang.reflect.Field.get() and java.lang.reflect.Field.set(). Ideally I would like to generate for each property an invoker like the following. public interface PropertyAccessor<S, V> { public void set(S source, V value); public V get(S source); } Now when I scan the class I can create a static inner class of PurchaseOrder like so. static class customer_Field implements PropertyAccessor<PurchaseOrder, Customer> { public void set(PurchaseOrder order, Customer customer) { order.customer = customer; } public Customer get(PurchaseOrder order) { return order.customer; } } With these I totally avoid the cost of reflection. I can now set and get from my instances with native performance. Can anyone tell me how I would do this. A code example would be great. I have searched the net for a good example but can find nothing like this. The ASM and Javasist examples are pretty poor also. The key here is that I have an interface that I can pass around. So I can have various implementations, perhaps one with Java Reflection as a default, one with ASM, and one with Javassist? Any help would be greatly appreciated.

• Strange Problem with Webservice and IIS

  - by Rene

  Hello there, I have a Problem which confuses me a little bit, resp. where I don't have any Idea about what it could be. The System I'm using is Windows Vista, IIS 7.0, VS2008, Windows Software Factory, Entity Framework, WCF. The Binding for all Webservices is wshttpbinding. I'm using a Webservice hosted in IIS. This Webservice uses/calls another Webservice (also installed in the IIS). If I use a client calling the first Webservice (which calls the second Webservice) it works fine for about 4-10 Times. And then (it is repeatable to get this Problem, but sometimes it happens after 4, sometimes after 10 Time, but it always will happen), the Service and the IIS gets stuck. Stuck means, that this Webservice isn't callable anymore and generates an timeout after 1 minute. Even increasing Timeout doesn't change anything. If i try to restart the IIS I get an timeout error. So the IIS is also "stuck" (it is not really stuck, but I can't restart it). Only if I kill the w3wp.exe IIS is restartable and the Webservice will work again (until i again call this service several times). The logfiles (i'm no expert in things like logging or where to find/enable such logs, so to say : i'm a newbie) like http-logging, Event Viewer or WCF-Message Logging don't show any hints upon the source of the problem. I don't have this problem when I'm using a Webservice which doesn't call another Service. Calling a Webservice is done by Service Reference (I'm using no Proxy-Classes), but I think this should be no Problem. I have no idea of what is happening, nor how to solve this Problem.

• Cookie add in the Global.asax warning in application log

  In my Global.ASAX file i have the following: System.Web.HttpCookie isAccess = new System.Web.HttpCookie("IsAccess"); isAccess.Expires = DateTime.Now.AddDays(-1); isAccess.Value = ""; System.Web.HttpContext.Current.Response.Cookies.Add(isAccess); So every time this method this is logged in the application events as a warning: Event code: 3005 Event message: An unhandled exception has occurred.

• oracle sequence init

  - by gospodin

  I wanted to export 3 tables from db1 into db2. Before the export starts, I will create the sequences for those 3 tables. CREATE SEQUENCE TEST_SEQ START WITH 1 INCREMENT BY 1; After the export, I will reinitialize sequnce values to match the max(id) + 1 from the table. CREATE OR REPLACE PROCEDURE "TEST_SEQUENCE" AUTHID CURRENT_USER is v_num number; begin select max(ID) into v_num from TABLE_1; EXECUTE IMMEDIATE 'ALTER SEQUENCE TEST_SEQ INCREMENT BY ' || v_num; EXECUTE IMMEDIATE 'ALTER SEQUENCE 1TEST_SEQ INCREMENT BY 1'; end; / show errors; execute TEST_SEQ; This procedure compiles and executes without problems. But when I want to check t he last value of the sequence, like select TEST_SEQ.nextval from dual; I still get the "1". Can someone tell me why my procedure did not impact my sequence? ps. I am using oracle sql developper to pass sql. Thanks

• C# udp can not receive any data

  - by StoneHeart

  here is my code Socket sck = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); sck.Bind(new IPEndPoint(IPAddress.Any, 0)); // Broadcast to find server string msg = "Imlookingforaserver:" + udp_listen_port; byte[] sendBytes4 = Encoding.ASCII.GetBytes(msg); IPEndPoint groupEP = new IPEndPoint(IPAddress.Parse("255.255.255.255"), server_port); sck.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Broadcast, 1); sck.SendTo(sendBytes4, groupEP); //Wait response from server Socket sck2 = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); sck2.Bind(new IPEndPoint(IPAddress.Any, udp_listen_port)); byte[] buffer = new byte[128]; EndPoint remoteEndPoint = new IPEndPoint(IPAddress.Any, udp_listen_port); sck2.ReceiveFrom(buffer, ref remoteEndPoint); //<<< I never pass this line I use above code to try find a server. First i broadcast a message and then i wait response from server. A test i made with the server written in c++ and running in windows vista, client written in C# and run on the same machine with server. Problem is: The server can receive message which client broadcast. But client can not receive anything from server. I try to write a client with c++ and it work like a charm, i think my problem is in C# client.

• JS: capture a static snapshot of an object at a point in time with a method

  - by Barney

  I have a JS object I use to store DOM info for easy reference in an elaborate GUI. It starts like this: var dom = { m:{ old:{}, page:{x:0,y:0}, view:{x:0,y:0}, update:function(){ this.old = this; this.page.x = $(window).width(); this.page.y = $(window).height(); this.view.x = $(document).width(); this.view.y = window.innerHeight || $(window).height(); } I call the function on window resize: $(window).resize(function(){dom.m.update()}); The problem is with dom.m.old. I would have thought that by calling it in the dom.m.update() method before the new values for the other properties are assigned, at any point in time dom.m.old would contain a snapshot of the dom.m object as of the last update – but instead, it's always identical to dom.m. I've just got a pointless recursion method. Why isn't this working? How can I get a static snapshot of the object that won't update without being specifically told to? Comments explaining how I shouldn't even want to be doing anything remotely like this in the first place are very welcome :)

• Using MEF with exporting project that uses resources (xml) contained in the xap.

  - by JSmyth

  I'm doing a proof of concept app in SL4 using MEF and as part of the app I am importing another xap from an existing Silverlight Project and displaying it in my host project. The problem is that the existing app uses some .xml files (as content) and it uses linq2xml to load these files which are (assumed to be) bundled in the xap. When I compose the application the initalization fails because the host app doesn't contain the xml files. If I copy these xml files into the host project and run it the composition works fine. However, I need to keep the xml files in the original project. Is there a way that I can download a xap and look at it's contents for xml files and then load them into the host xap at runtime so that after the compostion takes place the xml resources that are required can be found? Or should I work out some kind of contract with an import/export to pass the xml files to the host xap? As the people developing the imported xaps (should the project go ahead) are from a different company, I would like to keep changes to the way they develop their apps to a minimum.
