  • Strage character encoding problem with Eclipse / Spring / Tomcat 6

    - by Czar
    Hi, I have been trying things all da but can't get a proper solution. My problem is: I am developing a Spring MVC based app in my local Tomcat. My MYSQl database has UTF-8 encoding set, all content in there displays properly when using phpMyAdmin. Also the output in LOG files using log4j in catalina.out works fine. My JSP pages are configured by <!-- encoding --> <%@ page contentType="text/html; charset=UTF-8" %> <%@ page pageEncoding="UTF-8" %> Also showing data on my JSP works fine. I can also send data from my Controller without any DB intereference using special chars, e.g. String str = "UTF-8 Test: Ä Ö Ü ß è é â"; logger.debug(str); mav.addObject("utftest", str); That displays correctly in log and on jsp page in browser. BUT: When having special chars directly in my JSP file, e.g. for text in headers, this does not work. FF and Google Chrome display strange chars but report the page to be UTF-8. When switching to Latin, the chars just get more and more strange. Same problem when showing text tokens from my messages.properties file, although Eclipse says when right-clicking that UTF-8 will be used. I am a little it lost and don't know where to check now. Summary: DB storage is fine DB output on JSP is fine Output on JSP directly form controller is fine even reading in form forms is fine .properties files and JSP text is not fine !!! Any ideas? I really appreciate and tips.

  • Math on Django Templates

    - by Leandro Abilio
    Here's another question about Django. I have this code: views.py cursor = connections['cdr'].cursor() calls = cursor.execute("SELECT * FROM cdr where calldate > '%s'" %(start_date)) result = [SQLRow(cursor, r) for r in cursor.fetchall()] return render_to_response("cdr_user.html", {'calls':result }, context_instance=RequestContext(request)) I use a MySQL query like that because the database is not part of a django project. My cdr table has a field called duration, I need to divide that by 60 and multiply the result by a float number like 0.16. Is there a way to multiply this values using the template tags? If not, is there a good way to do it in my views? My template is like this: {% for call in calls %} <tr class="{% cycle 'odd' 'even' %}"><h3> <td valign="middle" align="center"><h3>{{ call.calldate }}</h3></td> <td valign="middle" align="center"><h3>{{ call.disposition }}</h3></td> <td valign="middle" align="center"><h3>{{ call.dst }}</h3></td> <td valign="middle" align="center"><h3>{{ call.billsec }}</h3></td> <td valign="middle" align="center">{{ (call.billsec/60)*0.16 }}</td></h3> </tr> {% endfor %} The last is where I need to show the value, I know the "(call.billsec/60)*0.16" is impossible to be done there. I wrote it just to represent what I need to show.

  • Alternatives to storing Moose object using Apache::Session with CODE references

    - by Hartmut Behrens
    I have a Moose class that i would like to store using Apache::Session::File. However, Apache::Session::File by default will not store it and instead i get the error message: (in cleanup) Can't store CODE items at blib\lib\Storable.pm (autosplit into blib\lib\auto\Storable\_freeze.al)... This problem can be circumvented by setting $Storable::Deparse = 1; $Storable::Eval = 1; in order to allow CODE references to be serialized. The offending method in the Moose class is listed below, which retrieves a column from a mysql database: sub _build_cell_generic { my ($self,$col) = @_; my $sth = $self->call_dbh('prepare','select '.$col.' from '.$self->TABLE.' where CI = ? and LAC = ? and IMPORTDATE = ?'); $sth->execute($self->CI,$self->LAC,$self->IMPORTDATE); my $val = $sth->fetchrow_array; $sth->finish; return defined $val ? $val : undef; } So presumably the dbh object (isa DBIx::Connector) contains CODE references. Is there a better alternative in order to allow serialization of this Moose class than setting $Storable::Deparse and $Storable::Eval ?

  • DataGridView in VB.net will not allow me to update

    - by Marc
    I have a datagridview with a dataTable as the dataSource. The user can add new rows to the datadridview, but I dont display the primary key column (for obvious reasons) and set it to .visible = false. When I need to update the information in the datagridview to the database, I use the sqlClient.SqlCommandBuilder to then update the underlying datasource (the dataTable mentioned above). Now, because the hidden column is the primary key, I loop through the datagridview and programically add the required primary key field to each new row that does not already contain a primary key (user added rows). This works great 95% of the time... The problem is when the user somehow gives focus at some point (any point) to that bottom row on the datagridview, below their added rows, that is used to add new rows. The update command gives me an error stating that it cannot insert null into the primary key field, even though when checking all the values in every row, it is definitely NOT null for any of them. I have tried to trap for row.isNewRow (as the field never shows null) and deleting that row, but I get an error stating I can not delete an uncommitted row. If the focus is never given to that empty row beneath the existing rows and user added rows, the update works fine. What is going on?!

  • ASP.NET: aggregating validators in a user control

    - by orsogufo
    I am developing a web application where I would like to perform a set of validations on a certain field (an account name in the specific case). I need to check that the value is not empty, matches a certain pattern and is not already used. I tried to create a UserControl that aggregates a RequiredFieldValidator, a RegexValidator and a CustomValidator, then I created a ControlToValidate property like this: public partial class AccountNameValidator : System.Web.UI.UserControl { public string ControlToValidate { get { return ViewState["ControlToValidate"] as string; } set { ViewState["ControlToValidate"] = value; AccountNameRequiredFieldValidator.ControlToValidate = value; AccountNameRegexValidator.ControlToValidate = value; AccountNameUniqueValidator.ControlToValidate = value; } } } However, if I insert the control on a page and set ControlToValidate to some control ID, when the page loads I get an error that says Unable to find control id 'AccountName' referenced by the 'ControlToValidate' property of 'AccountNameRequiredFieldValidator', which makes me think that the controls inside my UserControl cannot resolve correctly the controls in the parent page. So, I have two questions: 1) Is it possible to have validator controls inside a UserControl validate a control in the parent page? 2) Is it correct and good practice to "aggregate" multiple validator controls in a UserControl? If not, what is the standard way to proceed?

  • Find first item inside angular brackets after occurrence of other item, using RegEx, in C#

    - by Mihaela
    I have an xml-like text, in which I would like to find the item that occurs in the first occurrence of a certain pattern: typically: ... <PropertyGroup><name>true</name></PropertyGroup><PropertyGroup>.... .... Could also be ... <PropertyGroup> <name> true</name> </PropertyGroup> ... <PropertyGroup> ... In the above, I need to extract the "name". My initial assumption was that all occurrences were to be in one line, and I wrote my code using string properties, but it is very difficult o take in consideration every possibility, and only RegEx can save me. I just don't know how to write it... I Have started with something like this: Regex regex = new Regex("(?<=<PropertyGroup>#)<+"); Match matches = regex.Matches(Text)[0]; MessageBox.Show(matches.ToString()); I think this finds the first item after a <PropertyGroup>, but I don't know how to make it get the item within the angular brackets... (which may be after one or more newlines, and/or spaces). I know that there are utilities for parsing xml, but I am looking for something simple to insert in a c# program Can someone please help me ? Thank you very much.

  • Table Design For SystemSettings, Best Model

    - by Chris L
    Someone suggested moving a table full of settings, where each column is a setting name(or type) and the rows are the customers & their respective settings for each setting. ID | IsAdmin | ImagePath ------------------------------ 12 | 1          | \path\to\images 34 | 0          | \path\to\images The downside to this is every time we want a new setting name(or type) we alter the table(via sql) and add the new (column)setting name/type. Then update the rows(so that each customer now has a value for that setting). The new table design proposal. The proposal is to have a column for setting name and another column for setting. ID | SettingName | SettingValue ---------------------------- 12 | IsAdmin        | 1 12 | ImagePath   | \path\to\images 34 | IsAdmin        | 0 34 | ImagePath   | \path\to\images The point they made was that adding a new setting was as easy as a simple insert statement to the row, no added column. But something doesn't feel right about the second design, it looks bad, but I can't come up with any arguments against it. Am I wrong?

  • How upload files to azure in background with Delphi and OmniThread?

    - by mamcx
    I have tried to upload +100 files to azure with Delphi. However, the calls block the main thread, so I want to do this with a async call or with a background thread. This is what I do now (like explained here): procedure TCloudManager.UploadTask(const input: TOmniValue; var output: TOmniValue); var FileTask:TFileTask; begin FileTask := input.AsRecord<TFileTask>; Upload(FileTask.BaseFolder, FileTask.LocalFile, FileTask.CloudFile); end; function TCloudManager.MassiveUpload(const BaseFolder: String; Files: TDictionary<String, String>): TStringList; var pipeline: IOmniPipeline; FileInfo : TPair<String,String>; FileTask:TFileTask; begin // set up pipeline pipeline := Parallel.Pipeline .Stage(UploadTask) .NumTasks(Environment.Process.Affinity.Count * 2) .Run; // insert URLs to be retrieved for FileInfo in Files do begin FileTask.LocalFile := FileInfo.Key; FileTask.CloudFile := FileInfo.Value; FileTask.BaseFolder := BaseFolder; pipeline.Input.Add(TOmniValue.FromRecord(FileTask)); end;//for pipeline.Input.CompleteAdding; // wait for pipeline to complete pipeline.WaitFor(INFINITE); end; However this block too (why? I don't understand).

  • How to localize an app on Google App Engine?

    - by Petri Pennanen
    What options are there for localizing an app on Google App Engine? How do you do it using Webapp, Django, web2py or [insert framework here]. 1. Readable URLs and entity key names Readable URLs are good for usability and search engine optimization (Stack Overflow is a good example on how to do it). On Google App Engine, key based queries are recommended for performance reasons. It follows that it is good practice to use the entity key name in the URL, so that the entity can be fetched from the datastore as quickly as possible. Currently I use the function below to create key names: import re import unicodedata def urlify(unicode_string): """Translates latin1 unicode strings to url friendly ASCII. Converts accented latin1 characters to their non-accented ASCII counterparts, converts to lowercase, converts spaces to hyphens and removes all characters that are not alphanumeric ASCII. Arguments unicode_string: Unicode encoded string. Returns String consisting of alphanumeric (ASCII) characters and hyphens. """ str = unicodedata.normalize('NFKD', unicode_string).encode('ASCII', 'ignore') str = re.sub('[^\w\s-]', '', str).strip().lower() return re.sub('[-\s]+', '-', str) This works fine for English and Swedish, however it will fail for non-western scripts and remove letters from some western ones (like Norwegian and Danish with their œ and ø). Can anyone suggest a method that works with more languages? 2. Translating templates Does Django internationalization and localization work on Google App Engine? Are there any extra steps that must be performed? Is it possible to use Django i18n and l10n for Django templates while using Webapp? The Jinja2 template language provides integration with Babel. How well does this work, in your experience? What options are avilable for your chosen template language? 3. Translated datastore content When serving content from (or storing it to) the datastore: Is there a better way than getting the *accept_language* parameter from the HTTP request and matching this with a language property that you have set with each entity?

  • LINQ-To-SQL and Mapping Table Deletions

    - by Jake
    I have a many-to-many relationship between two tables, let's say Friends and Foods. If a friend likes a food I stick a row into the FriendsFoods table, like this: ID Friend Food 1 'Tom' 'Pizza' FriendsFoods has a Primary Key 'ID', and two non-null foreign keys 'Friend' and 'Food' to the 'Friends' and 'Foods' tables, respectively. Now suppose I have a Friend tom .NET object corresponding to 'Tom', and Tom no longer likes pizza (what is wrong with him?) FriendsFoods ff = tblFriendsFoods.Where(x => x.Friend.Name == 'Tom' && x.Food.Name == 'Pizza').Single(); tom.FriendsFoods.Remove(ff); pizza.FriendsFoods.Remove(ff); If I try to SubmitChanges() on the DataContext, I get an exception because it attempts to insert a null into the Friend and Food columns in the FriendsFoods table. I'm sure I can put together some kind of convoluted logic to track changes to the FriendsFoods table, intercept SubmitChanges() calls, etc to try and get this to work the way I want, but is there a nice, clean way to remove a Many-To-Many relationship with LINQ-To-SQL?

  • Doctrine unsigned validation error storing created_at

    - by Alex Dean
    Hi, I'm having problems with the Timestampable functionality in Doctrine 1.2.2. The error I get on trying to save() my Record is: Uncaught exception 'Doctrine_Validator_Exception' with message 'Validation failed in class XXX 1 field had validation error: * 1 validator failed on created_at (unsigned) ' in ... I've created the relevant field in the MySQL table as: created_at DATETIME NOT NULL, Then in setTableDefinition() I have: $this->hasColumn('created_at', 'timestamp', null, array( 'type' => 'timestamp', 'fixed' => false, 'unsigned' => false, 'primary' => false, 'notnull' => true, 'autoincrement' => false, )); Which is taken straight from the output of generateModelsFromDb(). And finally my setUp() looks like: public function setUp() { parent::setUp(); $this->actAs('Timestampable', array( 'created' => array( 'name' => 'created_at', 'type' => 'timestamp', 'format' => 'Y-m-d H:i:s', 'disabled' => false, 'options' => array() ), 'updated' => array( 'disabled' => true ))); } (I've tried not defining all of those fields for 'created', but I get the same problem.) I'm a bit stumped as to what I'm doing wrong - for one thing I can't see why Doctrine would be running any unsigned checks against a 'timestamp' datatype... Any help gratefully received! Alex

  • How to integrate a Ipython console in a PyQT application

    - by user1800689
    I am developing PyQt software for my lab. In this software, I am loading different kind of RAW and analyzed data from a mySQL database (usually in arrays). I would like to integrate an Iython console in a Widget, so that I could interact easily with these data. I had some difficulties with Ipython 0.13 to do this. Here is what I already have (The whole code is very long, so I just show the part containing the widget, the Ipython console and the corresponding import line, if you need more, just tell me): ##I load everything useful to my application, including the following line from IPython.frontend.qt.console.qtconsoleapp import IPythonQtConsoleApp ##then is my whole software ##here is a class containing the Graphical User Interface elements. A button call the following function. self.Shell_Widget is the widget containing the Ipython console, self.MainWindow is the application mainwindow def EmbeddedIpython(self): """ This function should launch an Ipython console """ self.Shell_Widget = QtGui.QDockWidget(self.MainWindow) #Widget creation self.MainWindow.addDockWidget(4,self.Shell_Widget) self.Shell_Widget.setMinimumSize(400,420) console = IPythonQtConsoleApp() #Console Creation console.initialize() console.start() self.Shell_Widget.show() So, as wanted, an Ipython console is launched, and seems to work, but I can not access the whole application variables ,arrays etc... I think the Ipython console is launched independently from my software, but here is my limit in programming... Does someone know how to launch Ipython within my application? Maybe a missing parameter, or a different way to integrate Ipython. for information, this doesn't work: Embedding IPython Qt console in a PyQt application Thank you for your help!!

  • Good way to handle inline-edit form using Rails and jQuery

    - by Tim Sullivan
    I have a list of items, being displayed in a series of DIVs. When someone clicks on an "edit" link, I want to replace the div with a form that will let them edit the contents of that item in a nice way. I'm trying to think of the ideal way to handle this. Do I create a hidden edit form for every item in the list, and hook the edit link to reveal it, like this: <div> <a href="#">edit</a> Item One <div id="edit_1202" class="editform">Edit form goes here</div> </div> <div> <a href="#">edit</a> Item Two <div id="edit_2318" class="editform">Edit form goes here</div> </div> Or is there a better way to fetch the data and insert the form's HTML into the right spot? Remember, I'm using jQuery, so I can't use the prototype helpers. Thanks!

  • How can I get the Hibernate Configuration object from Spring?

    - by Wayne Russell
    Hi, I am trying to obtain Spring-defined Hibernate Configuration and SessionFactory objects in my non-Spring code. The following is the definition in my applicationContext.xml file: Code: <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.cglib.use_reflection_optimizer">true</prop> <prop key="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</prop> </props> </property> <property name="dataSource"> <ref bean="dataSource"/> </property> </bean> If I now call getBean("sessionFactory"), I am returned a $Proxy0 object which appears to be a proxy for the Hibernate SessionFactory object. But that isn't what I want - I need the LocalSessionFactoryBean itself because I need access to the Configuration as well as the SessionFactory. The reason I need the Configuration object is that our framework is able to use Hibernate's dynamic model to automatically insert mappings at runtime; this requires that we change the Configuration and rebuild the SessionFactory. Really, all we're trying to do is obtain the Hibernate config that already exists in Spring so that those of our customers that already have that information in Spring don't need to duplicate it into a hibernate.cfg.xml file in order to use our Hibernate features.

  • TinyMCE Image Alignment

    - by will.earp.co.uk
    TinyMCE has always been a little difficult to align images. Either the align tag, or adding style="float: left;" has been it solution. Ideally I would just like to add class="left" or class="right" so that I can set the border and margins of the image. Up until now the only way to do this without using the advimage plugin was to insert the image, then select it, the select a style from the style menu. Ideally I should be able to use the align control in the image dialogue to set the alignment class or use the alignment controls on the toolbar when in the main editing window. I have just again started looking at a solution to this, now that IE6 is finally starting to die, I can use CSS attributes in selectors, so IMG[style="float: left;"] {} Works, but I would rather use a class incase there are any other style attributes which will cause the selector to fail. And it doesn't work in IE6, and you know some corporate clients will still be running the bloody thing! So I looked through the TinyMCE documentation and found the formats configuration option, that seems to allow you to specify how tinyMCE applies code for various operations. Here I can add the IMG tag as a selector, and have classes: "left" for the alignleft function. This applies the class correctly when the alignment is selected from the toolbar, but it still writes an inline style when the alignment is selected through the image dialogue. Am I doing something wrong or is there a better way of doing this that will allow my clients to select image alignment from both the image dialogue and the toolbar, whilst applying a class to the image?

  • Storing URLs while Spidering

    - by itemio
    I created a little web spider in python which I'm using to collect URLs. I'm not interested in the content. Right now I'm keeping all the visited URLs in a set in memory, because I don't want my spider to visit URLs twice. Of course that's a very limited way of accomplishing this. So what's the best way to keep track of my visited URLs? Should I use a database? * which one? MySQL, sqlite, postgre? * how should I save the URLs? As a primary key trying to insert every URL before visiting it? Or should I write them to a file? * one file? * multiple files? how should I design the file-structure? I'm sure there are books and a lot of papers on this or similar topics. Can you give me some advice what I should read?

The UpdateCommand is utter madness. Thanks & Best Regards: Matti

  • Ideal Multi-Developer Lamp Stack?

    - by devians
    I would like to build an 'ideal' lamp development stack. Dual Server (Virtualised, ESX) Apache / PHP on one, Databases (MySQL, PgSQL, etc) on the other. User (Developer) Manageable mini environments, or instance. Each developer instance shares the top level config (available modules and default config etc) A developer should have control over their apache and php version for each project. A developer might be able to change minor settings, ie magicquotes on for legacy code. Each project would determine its database provider in its code The idea is that it is one administrate-able server that I can control, and provide globally configured things like APC, Memcached, XDebug etc. Then by moving into subsets for each project, i can allow my users to quickly control their environments for various projects. Essentially I'm proposing the typical system of a developer running their own stack on their own machine, but centralised. In this way I'd hope to avoid problems like Cross OS code problems, database inconsistencies, slightly different installs producing bugs etc. I'm happy to manage this in custom builds from source, but if at all possible it would be great to have a large portion of it managed with some sort of package management. We typically use CentOS, so yum? Has anyone ever built anything like this before? Is there something turnkey that is similar to what I have described? Are there any useful guides I should be reading in order to build something like this?

  • Force full garbage collection when memory occupation goes beyond a certain threshold

    - by Silvio Donnini
    I have a server application that, in rare occasions, can allocate large chunks of memory. It's not a memory leak, as these chunks can be claimed back by the garbage collector by executing a full garbage collection. Normal garbage collection frees amounts of memory that are too small: it is not adequate in this context. The garbage collector executes these full GCs when it deems appropriate, namely when the memory footprint of the application nears the allotted maximum specified with -Xmx. That would be ok, if it wasn't for the fact that these problematic memory allocations come in bursts, and can cause OutOfMemoryErrors due to the fact that the jvm is not able to perform a GC quickly enough to free the required memory. If I manually call System.gc() beforehand, I can prevent this situation. Anyway, I'd prefer not having to monitor my jvm's memory allocation myself (or insert memory management into my application's logic); it would be nice if there was a way to run the virtual machine with a memory threshold, over which full GCs would be executed automatically, in order to release very early the memory I'm going to need. Long story short: I need a way (a command line option?) to configure the jvm in order to release early a good amount of memory (i.e. perform a full GC) when memory occupation reaches a certain threshold, I don't care if this slows my application down every once in a while. All I've found till now are ways to modify the size of the generations, but that's not what I need (at least not directly). I'd appreciate your suggestions, Silvio P.S. I'm working on a way to avoid large allocations, but it could require a long time and meanwhile my app needs a little stability

  • rails test.log is always empty

    - by Raiden
    All the log entries generated when running tests with 'rake' are written to my development.log instead of test.log file Do I have to explicitly enable logging for test in enviornments/test.config?? (I'm using 'turn' gem to format test output, Can that cause an issue?) I'm running rails 2.3.5, ruby 1.8.7 I've all these gems installed for RAILS_ENV=test.

  • Can I write this regex in one step?

    - by Marin Doric
    This is the input string "23x +y-34 x + y+21x - 3y2-3x-y+2". I want to surround every '+' and '-' character with whitespaces but only if they are not allready sourrounded from left or right side. So my input string would look like this "23x + y - 34 x + y + 21x - 3y2 - 3x - y + 2". I wrote this code that does the job: Regex reg1 = new Regex(@"\+(?! )|\-(?! )"); input = reg1.Replace(input, delegate(Match m) { return m.Value + " "; }); Regex reg2 = new Regex(@"(?<! )\+|(?<! )\-"); input = reg2.Replace(input, delegate(Match m) { return " " + m.Value; }); explanation: reg1 // Match '+' followed by any character not ' ' (whitespace) or same thing for '-' reg2 // Same thing only that I match '+' or '-' not preceding by ' '(whitespace) delegate 1 and 2 just insert " " before and after m.Value ( match value ) Question is, is there a way to create just one regex and just one delegate? i.e. do this job in one step? I am a new to regex and I want to learn efficient way.
