• ValidatorResources not found in application

  - by jojolapin

  I had been told to deploy a *.war file within tomcat and this application should be working fine. But for an unknown reason all I get is: System Exception: javax.servlet.jsp.JspException: ValidatorResources not found in application scope under key "org.apache.commons.validator.VALIDATOR_RESOURCES" I know that this application has been developed with STRUTS and I can obtain the source. But as I am not a specialist in this field, I come to ask for some help. Could you tell me what file could generate this exception please?

• Why does C# not allow const and static on the same line?

  - by Cuga

  Why does C# not allow const and static on the same line? In Java, you must declare a field as 'static' and 'final' to act as a constant. Why does C# not let you declare const's as final? I make the further distinction that in Java, every interface is public and abstract, whether this is explicitly declared or not. Aren't const's effectively static in nature? WHy does C# balk at this?

• How to detect when an attribute is modified by calling reflection methods

  - by Oleg Pavliv

  I have the following class public class MyClass { private int myAttr; public void setAttr(int a) { myAttr = a; Thread.dumpStack(); } } That way I can detect any attempt to modify myAttr. Well, almost any. It does not work when someone modifies myAttr using Field.set() method. How can I trap Java reflection usage?

• Change date format (in DB or output) to dd/mm/yyyy - PHP MySQL

  - by Jess

  MySQL stores the date in my database (by default) as 'YYYY-MM-DD' The field type for my date is 'DATE' (I do not need any time storage).. Is there a simple way to change it by default to DD/MM/YYYY ? I call up different dates in 2 different tables, and no where in any of my code do I have anything resembling a date variable or anything! Hopefully this is a straight forward change?

• ASP.Net / MySQL : Translating content into several languages

  - by philwilks

  I have an ASP.Net website which uses a MySQL database for the back end. The website is an English e-commerce system, and we are looking at the possibility of translating it into about five other languages (French, Spanish etc). We will be getting human translators to perform the translation - we've looked at automated services but these aren't good enough. The static text on the site (e.g. headings, buttons etc) can easily be served up in multiple languages via .Net's built in localization features (resx files etc). The thing that I'm not so sure about it how best to store and retrieve the multi-language content in the database. For example, there is a products table that includes these fields... productId (int) categoryId (int) title (varchar) summary (varchar) description (text) features (text) The title, summary, description and features text would need to be available in all the different languages. Here are the two options that I've come up with... Create additional field for each language For example we could have titleEn, titleFr, titleEs etc for all the languages, and repeat this for all text columns. We would then adapt our code to use the appropriate field depending on the language selected. This feels a bit hacky, and also would lead to some very large tables. Also, if we wanted to add additional languages in the future it would be time consuming to add even more columns. Use a lookup table We could create a new table with the following format... textId | languageId | content ------------------------------- 10 | EN | Car 10 | FR | Voiture 10 | ES | Coche 11 | EN | Bike 11 | FR | Vélo We'd then adapt our products table to reference the appropriate textId for the title, summary, description and features instead of having the text stored in the product table. This seems much more elegant, but I can't think of a simple way of getting this data out of the database and onto the page without using complex SQL statements. Of course adding new languages in the future would be very simple compared to the previous option. I'd be very grateful for any suggestions about the best way to achieve this! Is there any "best practice" guidance out there? Has anyone done this before?

• Drupal show / hide fields in view

  - by SteD

  I would like to show / hide certain fields in my Drupal view accordingly to the user role. Provided I can only have this view to work with, how can I achieve this programmatically or there's some settings that I am not aware of in Drupal. P/S: I am aware of the access settings under basic settings in View but that would restrict access to the whole view, not field level.

• Quering computed fields in GORM

  - by Tihom

  I am trying to query the following HQL using GORM: MailMessage.executeQuery("toId, count(toId) from (SELECT toId, threadId FROM MailMessage as m WHERE receiveStatus = '$u' GROUP BY threadId, toId) as x group by x.toId") The problem is that count(toId) is a computed field doesn't exist in MailMessage and that I am using a subquery. I get the following error: java.lang.IllegalArgumentException: node to traverse cannot be null! Ideally, I would like to use a generic executeQuery which will return data of anytype. Is there such a thing?

• How would you structure your entity model for storing arbitrary key/value data with different data t

  - by Nathan Ridley

  I keep coming across scenarios where it will be useful to store a set of arbitrary data in a table using a per-row key/value model, rather than a rigid column/field model. The problem is, I want to store the values with their correct data type rather than converting everything to a string. This means I have to choose either a single table with multiple nullable columns, one for each data type, or a set of value tables, one for each data type. I'm also unsure as to whether I should use full third normal form and separate the keys into a separate table, referencing them via a foreign key from the value table(s), or if it would be better to keep things simple and store the string keys in the value table(s) and accept the duplication of strings. Old/bad: This solution makes adding additional values a pain in a fluid environment because the table needs to be modified regularly. MyTable ============================ ID Key1 Key2 Key3 int int string date ---------------------------- 1 Value1 Value2 Value3 2 Value4 Value5 Value6 Single Table Solution This solution allows simplicity via a single table. The querying code still needs to check for nulls to determine which data type the field is storing. A check constraint is probably also required to ensure only one of the value fields contains non-nulll data. DataValues ============================================================= ID RecordID Key IntValue StringValue DateValue int int string int string date ------------------------------------------------------------- 1 1 Key1 Value1 NULL NULL 2 1 Key2 NULL Value2 NULL 3 1 Key3 NULL NULL Value3 4 2 Key1 Value4 NULL NULL 5 2 Key2 NULL Value5 NULL 6 2 Key3 NULL NULL Value6 Multiple-Table Solution This solution allows for more concise purposing of each table, though the code needs to know the data type in advance as it needs to query a different table for each data type. Indexing is probably simpler and more efficient because there are less columns that need indexing. IntegerValues =============================== ID RecordID Key Value int int string int ------------------------------- 1 1 Key1 Value1 2 2 Key1 Value4 StringValues =============================== ID RecordID Key Value int int string string ------------------------------- 1 1 Key2 Value2 2 2 Key2 Value5 DateValues =============================== ID RecordID Key Value int int string date ------------------------------- 1 1 Key3 Value3 2 2 Key3 Value6 How do you approach this problem? Which solution is better? Also, should the key column be separated into a separate table and referenced via a foreign key or be should it be kept in the value table and bulk updated if for some reason the key name changes?

• How to profile object creation in Java?

  - by gooli

  The system I work with is creating a whole lot of objects and garbage collecting them all the time which results in a very steeply jagged graph of heap consumption. I would like to know which objects are being generated to tune the code, but I can't figure out a way to dump the heap at the moment the garbage collection starts. When I tried to initiate dumpHeap via JConsole manually at random times, I always got results after GC finished its run, and didn't get any useful data. Any notes on how to track down excessive temporary object creation are welcome.

• ASP.NET ObjectDataSource Sorting Twice

  Hello, I'm working with some existing code uses an objectDataSource and that calls a sort method inside a DLL that I don't have access to. I'm trying to add a custom field to sort and I basically want to re-sort after the initial sort. I don't know if this can be done but before the GridView is displayed, I need to intercept the code and sort the way I want to sort. Any ideas? I'm lost.

• Django form and User data

  - by Dean

  I have a model that looks like this: class Client(models.Model): name = models.CharField(max_length=100, primary_key=True) user = models.ForeignKey(User) class Contract(models.Model): title = models.CharField(max_length=100, primary_key=True) start_date = models.DateField() end_date = models.DateField() description = models.TextField() client = models.ForeignKey(Client) user = models.ForeignKey(User) How can i configure a django form so that only clients associated with that user show in the field in the form? My initial thought was this in my forms.py: client = forms.ModelChoiceField(queryset=Client.objects.filter(user__username = User.username)) But it didn't work. So how else would I go about it?
