• Mapping to a JSON method with url-pattern

  - by Brian

  I'm creating a Spring MVC application that will have a controller with 'RequestMapping'-annotated methods, including a JSON method. It currently has static content that resides in webapps/static, and the app itself resides in webapps/myapp. I assume that Catalina's default servlet is handling the static content, and my *.htm url-pattern in web.xml is returning the request for my JSP page, but I haven't been able to get the JSON method to be called. How do I write the url-pattern in the servlet mapping to do so? Using /* has not worked; it prevents the app from being accessed at all. Is there anything else to be aware of? EDIT: The url-pattern '/' appears to allow the JSON request through, because a 406 error is returned. What then would need to be modified to allow JSON to be returned?

• Nginx is sending proxy saved conent in gzip format

  - by Sandeep Manne

  Hi I used config given in this http://www.webtatic.com/blog/2008/04/page-level-caching-with-nginx/ for page level caching of php content the problem is that the cached page is saving in gzip format and it returning same gzip content to browser. I need the o/p like this "12:15:37 12:15:47" (Its coming for 1st time when the page is not cached) after that if request is resend it is returning ‹??????34²26±24à23Œ¸¸?`Î9”???

• Needs some help with an apache mod-rewrite issue

  - by mike

  I've modified my .htaccess file to have the following statement RewriteCond $1 !^index.php$ RewriteRule ^/?([^/]+)$ index.php?c=home&m=details&seo=$1 [L,NS] This allows me to use product URL's like this: http://domain.com/product_name However, when trying to access a file at the same level as index.php, it always calls the RewriteRule above and errors out. I need to be able to access files like below, but each URL currently attempts to load index.php. http://domain.com/about.htm http://domain.com/terms.htm http://domain.com/robots.txt etc Any suggestions on how I can modify my htaccess file to get this to work correctly?

• Exception when programmatically copying content type

  - by BeraCim

  Hi all: I'm getting exceptions when copying content type from one web to another: foreach (SPContentType destinationWebCt in destinationWeb.ContentTypes) { destinationWeb.ContentTypes.Add(existingWebCt); destinationWeb.Update(); } existingWebCt is the content type from another web e.g. /Site/Web. destinationWeb is the web that I wish to copy the content type to e.g. /Site/DestinationWeb. I got the SPException that says something like could not copy content type to scope. Then I decided to replace all "ContentTypes" to "AvailableContentTypes", but then I got the SPException saying this collcetion could not be modified. So how can I copy a content type to another web? Thanks.

• MySQL slow query

  - by andrhamm

  SELECT items.item_id, items.category_id, items.title, items.description, items.quality, items.type, items.status, items.price, items.posted, items.modified, zip_code.state_prefix, zip_code.city, books.isbn13, books.isbn10, books.authors, books.publisher FROM ( ( items LEFT JOIN bookitems ON items.item_id = bookitems.item_id ) LEFT JOIN books ON books.isbn13 = bookitems.isbn13 ) LEFT JOIN zip_code ON zip_code.zip_code = items.item_zip WHERE items.rid = $rid` I am running this query to get the list of a user's items and their location. The zip_code table has over 40k records and this might be the issue. It currently takes up to 15 seconds to return a list of about 20 items! What can I do to make this query more efficient?

• SQL: select random row from table where the ID of the row isn't in another table?

  - by johnrl

  I've been looking at fast ways to select a random row from a table and have found the following site: http://74.125.77.132/search?q=cache:http://jan.kneschke.de/projects/mysql/order-by-rand/&hl=en&strip=1 What I want to do is to select a random url from my table 'urls' that I DON'T have in my other table 'urlinfo'.The query I am using now selects a random url from 'urls' but I need it modified to only return a random url that is NOT in the 'urlinfo' table. Heres the query: SELECT url FROM urls JOIN (SELECT CEIL(RAND() * (SELECT MAX(urlid) FROM urls ) ) AS urlid ) AS r2 USING(urlid); And the two tables: CREATE TABLE urls ( urlid INT NOT NULL AUTO_INCREMENT PRIMARY KEY, url VARCHAR(255) NOT NULL, ) ENGINE=INNODB; CREATE TABLE urlinfo ( urlid INT NOT NULL PRIMARY KEY, urlinfo VARCHAR(10000), FOREIGN KEY (urlid) REFERENCES urls (urlid) ) ENGINE=INNODB;

• Django save, column specified twice

  - by realshadow

  Hey, I would like to save a modified model, but I get Programming error - that a field is specified twice. class ProductInfo(models.Model): product_info_id = models.AutoField(primary_key=True) language_id = models.IntegerField() product_id = models.IntegerField() description = models.TextField(blank=True) status = models.IntegerField() model = models.CharField(max_length=255, blank=True) label = models.ForeignKey(Category_info, verbose_name = 'Category_info', db_column = 'language_id', to_field = 'node_id', null = True) I get this error because the foreign key uses as db_column language_id. If I will delete it, my object will be saved properly. I dont quite understand whats going on and since I have defined almost all of my models this way, I fear its totally wrong or maybe I just missunderstood it... Any ideas? Regards

• MSI File/Registry failures to Windows Server 2008/Windows 7

  - by Luca

  I'm trying to deploy an application on Windows Server 2008 (SP2 x64) and Windows 7 (x64), using VS2005 Installer Project. The MSI version (I think) it the 2.0. Everything works fine, except that some registry keys and some files are not copied on the install machine. The MSI system doesn't notify about nothing (and I don't know whether MSI logs its operations). Are there incompatibilities between my MSI installer project and these new OSes? It seems to me that the OS protect itself for being modified in some part. For example, I'm trying to set the registry keys: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\WinLogon\SpecialAccounts\UserList\User but it is not created. In the same installer there are many other keys, which are created like expected (as they always did before on Windows XP and Windows Server 2003). What's going on?

• IIS Browser caching not working

  - by Karthik

  Hi, I have enabled caching in IIS 6 for all our static images and CSS(by right clicking on those folders in IIS and enabled Content Expiration after 30 days under HTTP Headers). When I run Google PageSpeed, and look at the resources tab, the status of those images and css shows up as 200, but I was expecting a 304(not modified). When I checked Yahoo.com in Pagespeed, all its images have a 304 status. So my caching is not working? or is this how IIS content expiration works. Any help would be appreciated.

• Designer throwing up an error!

  - by Luke

  I have a dropdown list that I want to show only certain options when a bool is true of false. if (mainForm.boolEdit == true) { this.cmbStatusBox.Items.AddRange(new object[] { "Cooking", "In-transit", "Delivered"}); } else { this.cmbStatusBox.Items.AddRange(new object[] { "Ordered"}); } I put this code into the saveForm.Designer.cs and got the following error: The designer cannot process the code at line 205: if (mainForm.boolEdit == true) { this.cmbStatusBox.Items.AddRange(new object[] { "Cooking", "In-transit", "Delivered"}); } else { this.cmbStatusBox.Items.AddRange(new object[] { "Ordered"}); } The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified. Please remove any changes and try opening the designer again. What are my alternatives?

• RedDot with Lotus Notes support

  - by fredde

  Hi, First post here in SO. I have a question within the area of CMS (RedDot) and possible integration of some Lotus Notes functionality. I'm very fresh in both areas. From my short research (did not find very much material regarding RedDot) I got the following: Contents in RedDot CMS can be accessed (and modified?) via the RQL API. (basicly xml messages) There exists a API developed for Java (jRQL). Lotus Notes has a developer kit called Lotus Expeditor Toolkit. My vague question is something like this: Is it possible to integrate a some kind of "content approver/manager" or any other useful CMS functionality from Lotus Notes into the RedDot CMS system? In that case I was thinking of using the jRQL and Lotus Expediton Toolkit so that the back end is fully using Java. Or is there any better solution? Regards Fredrik

• View a git diff-tree in a reasonable format

  - by Josh

  Howdy, I'm about to do a git svn dcommit to our svn repo -- and as is recommended in a number of places, I wanted to figure out exactly what I was going to be committing with a dry run. As such I ran: git svn dcommit -n This produced output: Committing to http://somerepo/svn/branches/somebranch diff-tree 1b937dacb302908602caedf1798171fb1b7afc81~1 1b937dacb302908602caedf1798171fb1b7afc81 How do I view this in a format that I can consume as a human? A list of modified files comes to mind. This is probably easy, but running git diff-tree on those hashes gives me a reference to a directory and a some other hashes, as well as some numbers. Not quite sure what to make of it. Thanks very much, Josh

• How do I catch generic fault exceptions in Fitnesse?

  - by Dan Ryan

  Previously within my Fitnesse fixture I was specifying an expected WCF exception using: exception[FaultException] Since then I have converted the WCF service to return a strongly typed FaultContract. I am now getting the following failure message: exception[FaultException`1: "A file with the name DMS Documents/testFileWord.doc already exists. It was last modified by SHAREPOINT\system on 09 Mar 2010 15:36:14 -0000."] This is not unexpected but how do I check for strongly typed fault exceptions? Please note I cannot include the fault message as part of the check as it contains a date which changes (I check this separately).

• CakePHP Bake association problem

  - by Apu

  I have only two tables in my database with a one-to-many relationship between them (user hasMany messages) and am trying to get basic CRUD functionality going. Bake detects the associations correctly and specifies them correctly inside the model classes, but in controllers and views it looks like Cake doesn't know anything about those associations -- I don't even get a select tag for user_id when I go add a new message. Has anyone come across this problem before? What can I be doing wrong? Table structure appears to be fine: CREATE TABLE users ( id int(11) NOT NULL AUTO_INCREMENT, username varchar(255) NOT NULL, `password` varchar(255) NOT NULL, email varchar(255) NOT NULL, created datetime NOT NULL, modified datetime NOT NULL, PRIMARY KEY (id) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; CREATE TABLE IF NOT EXISTS `messages` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_id` int(11) NOT NULL, `content` varchar(255) NOT NULL, `created` datetime NOT NULL, `modified` datetime NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

• Quick / Built-in method for detecting table change in SQL Server?

  - by the-locster

  Is there a quick and easy way of telling if a table has changed in SQL Server? (I'm using SQL Server 2005). Something like an incrementing ID somewhere that updates on each INSERT, DELETE or UPDATE that I can keep track of. I noticed there is a sys.objects.modify_date column for each table, but I don't think it's quite what I want because the docs say: Date the object was last modified by using an ALTER statement. If the object is a table or a view, modify_date also changes when a clustered index on the table or view is created or altered.

• Skinning WinAPI Controls

  - by Brad

  If you've ever seen an application in the Adobe Creative Suite 5 (CS5), you may have noticed that it doesn't look like the native Windows GUI.. They have modified it to have a different look to it. Where would someone begin to make an application that has a custom skin? CS5 uses the Adobe Source library for it's widget/control management, so I tried downloading and compiling the Adobe Source Library to see if I could make a nice skinned app like Photoshop CS5, but after finally getting it to compile and tested it, I realized the library was only for managing widgets and not skinning the GUI, like CS5 has. Where would I begin to make a nice skinned program like Adobe Cs5 applications? Can anyone point me in the right direction? Do I simply use the WM_PAINT Message from WinAPI and render my own widgets using openGL or something?

• keeping xmphp bot always online

  - by Gunjan

  I created a simple xmpp bot in PHP which connects to google talk server. I basically modified the cli_longrun example. When I run the script in browser the bot comes online and stays online for a while even after I close the tab on which the script was running (as it is just an infinite loop listening for events on the stream). But after a while the bot becomes offline. The question is how do I keep the bot always online. One way I can think of is to run a cron that would disconnect the earlier one and start a new session. But is there a better approch?

• aspnet_reqsql not working at all

  - by user252160

  I would like to create the ASP.NET User database template on a database of my own, because I'd like to fully untegrate the user system with the rest of my DB. As I've read, i needed to use the aspnet_regsql tool. I put all the options (because my database is running on SQLEXPRESS and is in an mdf file in my project's folder). the program starts and seemingly runs without any errors, however, when I open the database after that, not tables or stored procedures have been added. One more thing: I did one more test. I intentionally gave the -d option a wrong mdf file address, and surprisingly, the program "finished" correctly, yet no file was crated or modified whatsoever.

• DB2 load partitioned data in parallel

  - by Erik Paulson

  I have a 10-node DB2 9.5 database, with raw data on each machine (ie node1:/scratch/data/dataset.1 node2:/scratch/data/dataset.2 ... node10:/scratch/data/dataset.10 There is no shared NFS mount - none of my machines could handle all of the datasets combined. each line of a dataset file is a long string of text, column delimited. The first column is the key. I don't know the hash function that DB2 will use, so dataset is not pre-partitioned. Short of renaming all of my files, is there any way to get DB2 to load them all in parallel? I'm trying to do something like load from '/scratch/data/dataset' of del modified by coldel| fastparse messages /dev/null replace into TESTDB.data_table part_file_location '/scratch/data'; but I have no idea how to suggest to db2 that it should look for dataset.1 on the first node, etc.

• flex/actionscript client entity state refresh on JPA update using Pimento EntityManager

  - by Chris

  My Flex application uses a client-side pimento EntityManager which fetches quite a few objects and associations. It does this by forcing eager fetching of particular association ends in the form of fetch plans. I would like to update the client whenever a change has been made to an entity existing in the EntityManager's cache. Is it possible to update the state of the changed entity ONLY, including updating which entities are associated, without resetting the state of these associated entities? I have setup an EntityListener with a JPA post-update method that notifies clients when a persisted entity has been updated. I want this to trigger a refresh for the modified client-side entity, but calling EntityManager.refresh(entity) resets all lazy associations to proxies. Initializing these proxies resets the associated entities, even if they were loaded previously. I'm looking for an efficient way to keep the client's state in synch with the server's state, at least with respect to the entities that have already been retrieved by the initial load.

• Why can XSLT not parse this XML?

  - by Matt W

  Taking the XSLT and XML from this page as an example: http://www.w3schools.com/xsl/xsl_transformation.asp I have an xml file which contains (above example modified): <?xml version="1.0" encoding="ISO-8859-1"?> <?xml-stylesheet type="text/xsl" href="cdcatalog.xsl"?> <catalog xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/"> <cd> In my case, the output contains nothing when the XSLT/XML is processed by the browser. The moment I remove the attributes from the element, it works. Problem is, I don't really have the option of pre-processing those attributes out of the file. Can anyone explain how to force the XSLT to work with the XML as is, please? After all, those attributes seem fairly standard. Many thanks, Matt.

• REST: Should I redirect to the version URL of an entity?

  - by sfussenegger

  I am currently working on a REST service. This service has an entity which has different versions, similar to Wikipedia articles. Now I'm wondering what I should return if for GET /article/4711 Should I use a (temporary) redirect to the current version, e.g. GET /article/4711/version/7 Or should I return the current version directly? Using redirects would considerably simplify HTTP caching (using Last-Modified) but has the disadvantages a redirect has (extra request, 'harder' to implement). Therefore I'm not sure whether this is good practice though. Any suggestions, advise, or experiences to share? (btw: ever tried search for "REST Version"? Everything you get is about the version of the API rather than entities. So please bear with me if this is a duplicate.)

• Using a single visual studio 2005 solution with multiple source control applications

  - by Bas Bossink

  In my recent SO question I was helped tremendously in using git as a front-end to ClearCase. However actually trying the suggested answer(s) led to further complications. Visual Studio keeps a reference to the used source control provider in both the .sln as well as the .csproj files. I tried resolving this issue by keeping a modified copy of the .sln with the source control provider paragraph removed but this did not help since each project also has some source control provider information. I don't want to keep private copies of all the projects since this would be a maintenance nightmare. Do any of you have suggestions on how to resolve this issue?

• Inserting nil Values into Sqlite Database?

  - by Chris

  I am working on an iPhone App where I am pulling data from an XML file and inserting it into a sqlite database located in the App. I am able to successfully do this process, but it appears that if I try to sqlite3_bind_text with a NSString that has a value of "nil", the App quickly dies. This is an example of code that fails: (modified for this example) // idvar = 1 // valuevar = nil const char *sqlStatement = "insert into mytable (id, value) VALUES(?, ?)"; sqlite3_stmt *compiledStatement = nil; sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL); sqlite3_bind_int(compiledStatement, 1, [idvar intValue]);; sqlite3_bind_text(compiledStatement, 2, [valuevar UTF8String], -1, SQLITE_TRANSIENT);

• VSTO: Attach meta-data to a cell in Excel?

  - by Gustav

  Hi! I'm using VSTO to create an Excel Add-on. This add-on retrieves and display alot of data from a sql-server. This works great, but later on I plan to access some of the data inside excel and modify it in some ways. My problem is that I need a way of classify cells that I want to modify. Is there any way to add meta-data to a cell to know if it is a cell that should be modified? E.g. add a attribute to the cell, e.g. "editable_cell", and do something like Excel.FindCellsWithAttribute("editable_cell") to find the sought after cells? Thanks! /Gustav
