• Load application context problem in Maven managed spring-test TestNg

  - by joejax

  I try to setup a project with spring-test using TestNg in Maven. The code is like: @ContextConfiguration(locations={"test-context.xml"}) public class AppTest extends AbstractTestNGSpringContextTests { @Test public void testApp() { assert true; } } A test-context.xml simply defined a bean: <bean id="app" class="org.sonatype.mavenbook.simple.App"/> I got error for Failed to load ApplicationContext when running mvn test from command line, seems it cannot find the test-context.xml file; however, I can get it run correctly inside Eclipse (with TestNg plugin). So, test-context.xml is under src/test/resources/, how do I indicate this in the pom.xml so that 'mvn test' command will work? Thanks, UPDATE: Thanks for the reply. Cannot load context file error was caused by I moved the file arround in different location since I though the classpath was the problem. Now I found the context file seems loaded from the Maven output, but the test is failed: Running TestSuite May 25, 2010 9:55:13 AM org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions INFO: Loading XML bean definitions from class path resource [test-context.xml] May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext prepareRefresh INFO: Refreshing org.springframework.context.support.GenericApplicationContext@171bbc9: display name [org.springframework.context.support.GenericApplicationContext@171bbc9]; startup date [Tue May 25 09:55:13 PDT 2010]; root of context hierarchy May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext obtainFreshBeanFactory INFO: Bean factory for application context [org.springframework.context.support.GenericApplicationContext@171bbc9]: org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99 May 25, 2010 9:55:13 AM org.springframework.beans.factory.support.DefaultListableBeanFactory preInstantiateSingletons INFO: Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99: defining beans [app,org.springframework.context.annotation.internalCommonAnnotationProcessor,org.springframework.context.annotation.internalAutowiredAnnotationProcessor,org.springframework.context.annotation.internalRequiredAnnotationProcessor]; root of factory hierarchy Tests run: 3, Failures: 2, Errors: 0, Skipped: 1, Time elapsed: 0.63 sec If I use spring-test version 3.0.2.RELEASE, the error becomes: org.springframework.test.context.testng.AbstractTestNGSpringContextTests.springTestContextPrepareTestInstance() is depending on nonexistent method null Here is the structure of the project: simple |-- pom.xml `-- src |-- main | `-- java `-- test |-- java `-- resources |-- test-context.xml `-- testng.xml testng.xml: <suite name="Suite" parallel="false"> <test name="Test"> <classes> <class name="org.sonatype.mavenbook.simple.AppTest"/> </classes> </test> </suite> test-context.xml: <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd" default-lazy-init="true"> <bean id="app" class="org.sonatype.mavenbook.simple.App"/> </beans> In the pom.xml, I add testng, spring, and spring-test artifacts, and plugin: <dependency> <groupId>org.testng</groupId> <artifactId>testng</artifactId> <version>5.1</version> <classifier>jdk15</classifier> <scope>test</scope> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring</artifactId> <version>2.5.6</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>2.5.6</version> <scope>test</scope> </dependency> <build> <finalName>simple</finalName> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <configuration> <suiteXmlFiles> <suiteXmlFile>src/test/resources/testng.xml</suiteXmlFile> </suiteXmlFiles> </configuration> </plugin> </plugins> Basically, I replaced 'A Simple Maven Project' Junit with TestNg, hope it works.

• Looking For a .NET Task Scheduling library

  - by Hounshell

  I'm looking for the following features: Scheduler uses SQL Server as the backing store Tasks can be scheduled by one application and executed by another I can have multiple applications, each of which handles a specific subset of tasks Tasks can be triggered at specific times, now, or based on the success or failure of other tasks Data can be attached to tasks There are a number of nice-to-have's, like a web management console, clustering/failover support, customizable logging, but they're not requirements. On the surface Quartz.NET has a nice interface and seems to fit the bill as it satisfies (1), (4 with some custom work) and (5), but I've been beating my head against (2) and (3) seems like I'd have to invest more effort than it's worth, especially given how convoluted the innards of it are. Any other libraries out there? Open source is preferred, with free as a close runner up. It's really hard to get management to pay for things like this when it's not their idea.

• Application development using google applications?

  - by Ali

  Hi guys I'm developing a collaboration system and our team has been at it for the past couple of years. However the boss suggested that we try and redevelop it using something robust. Basically our collaboration system incorporates a webmail client and a custom built contacts management system plus project management system. My boss likes the robustness of GMAIL and Google docs and really would like a solution that if possible could incorporate these two and other google applications - I'm not so sure how to get started on developing a custom application using google applications - especially consider the fact that in the long run we wish to host our collaboration system as a paid service - just like the services that 37signals basecamp and highrise have been.

• Crawling engine architecture - Java/ Perl integration

  - by Bigtwinz

  Hi all, I am looking to develop a management and administration solution around our webcrawling perl scripts. Basically, right now our scripts are saved in SVN and are manually kicked off by SysAdmin/devs etc. Everytime we need to retrieve data from new sources we have to create a ticket with business instructions and goals. As you can imagine, not an optimal solution. There are 3 consistent themes with this system: the retrieval of data has a "conceptual structure" for lack of a better phrase i.e. the retrieval of information follows a particular path we are only looking for very specific information so we dont have to really worry about extensive crawling for awhile (think thousands-tens of thousands of pages vs millions) crawls are url-based instead of site-based. As I enhance this alpha version to a more production-level beta I am looking to add automation and management of the retrieval of data. Additionally our other systems are Java (which I'm more proficient in) and I'd like to compartmentalize the perl aspects so we dont have to lean heavily on outside help. I've evaluated the usual suspects Nutch, Droid etc but the time spent on modifying those frameworks to suit our specific information retrieval cant be justified. So I'd like your thoughts regarding the following architecture. I want to create a solution which use Java as the interface for managing and execution of the perl scripts use Java for configuration and data access stick with perl for retrieval An example use case would be a data analyst delivers us a requirement for crawling perl developer creates the required script and uses this webapp to submit the script (which gets saved to the filesystem) the script gets kicked off from the webapp with specific parameters .... Webapp should be able to create multiple threads of the perl script to initiate multiple crawlers. So questions are what do you think how solid is integration between Java and Perl specifically from calling perl from java has someone used such a system which actually is part perl repository The goal really is to not have a whole bunch of unorganized perl scripts and put some management and organization on our information retrieval. Also, I know I can use perl do do the web part of what we want - but as I mentioned before - trying to keep perl focused. But it seems assbackwards I'm not adverse to making it an all perl solution. Open to any all suggestions and opinions. Thanks

• SSRS 2005 Copy reports, data model, etc.

  - by Jim

  Anyone know how I can copy the user reports (and model) someone has created to point at another database (same schema). I don't really want to recreate the data model becuase (a) it's really complicated and (b) the previous developer added lots of friendly column names. Thanks in advance, Jim

• MySQL Binary Storage using BLOB VS OS File System: large files, large quantities, large problems.

  - by Quantico773

  Hi Guys, Versions I am running (basically latest of everything): PHP: 5.3.1 MySQL: 5.1.41 Apache: 2.2.14 OS: CentOS (latest) Here is the situation. I have thousands of very important documents, ranging from customer contracts to voice signatures (recordings of customer authorisation for contracts), with file types including, but not limited to jpg, gif, png, tiff, doc, docx, xls, wav, mp3, pdf, etc. All of these documents are currently stored on several servers including Windows 32 bit, CentOS and Mac, among others. Some files are also stored on employees desktop computers and laptops, and some are still hard copies stored in hundreds of boxes and filing cabinets. Now because customers or lawyers could demand evidence of contracts at any time, my company has to be able to search and locate the correct document(s) effectively, for this reason ALL of these files have to be digitised (if not already) and correlated into some sort of order for searching and accessing. As the programmer, I have created a full Customer Relations Management tool that the whole company uses. This includes Customer Profiles management, Order and job Tracking tools, Job/sale creation and management modules, etc, and at the moment any file that is needed at a customer profile level (drivers licence, credit authority, etc) or at a job/sale level (contracts, voice signatures, etc) can be uploaded to the server and sits in a parent/child hierarchy structure, just like Windows Explorer or any other typical file managment model. The structure appears as such: drivers_license |- DL_123.jpg voice_signatures |- VS_123.wav |- VS_4567.wav contracts So the files are uplaoded using PHP and Apache, and are stored in the file system of the OS. At the time of uploading, certain information about the file(s) is stored in a MySQL database. Some of the information stored is: TABLE: FileUploads FileID CustomerID (the customer id that the file belongs to, they all have this.) JobID/SaleID (the id of the job/sale associated, if any.) FileSize FileType UploadedDateTime UploadedBy FilePath (the directory path the file is stored in.) FileName (current file name of uploaded file, combination of CustomerID and JobID/SaleID if applicable.) FileDescription OriginalFileName (original name of the source file when uploaded, including extension.) So as you can see, the file is linked to the database by the File Name. When I want to provide a customers' files for download to a user all I have to do is "SELECT * FROM FileUploads WHERE CustomerID = 123 OR JobID = 2345;" and this will output all the file details I require, and with the FilePath and FileName I can provide the link for download. http... server / FilePath / FileName There are a number of problems with this method: Storing files in this "database unconcious" environment means data integrity is not kept. If a record is deleted, the file may not be deleted also, or vice versa. Files are strewn all over the place, different servers, computers, etc. The file name is the ONLY thing matching the binary to the database and customer profile and customer records. etc, etc. There are so many reasons, some of which are described here: http://www.dreamwerx.net/site/article01 . Also there is an interesting article here too: sietch.net/ViewNewsItem.aspx?NewsItemID=124 . SO, after much research I have pretty much decided I am going to store ALL of these files in the database, as a BLOB or LONGBLOB, but there are still many considerations before I do this. I know that storing them in the database is a viable option, however there are a number of methods of storing them. I also know storing them is one thing; correlating and accessing them in a manageable way is another thing entirely. The article provided at this link: dreamwerx.net/site/article01 describes a way of splitting the uploaded binary files into 64kb chunks and storing each chunk with the FileID, and then streaming the actual binary file to the client using headers. This is a really cool idea since it alleviates preassure on the servers memory; instead of loading an entire 100mb file into the RAM and then sending it to the client, it is doing it 64kb at a time. I have tried this (and updated his scripts) and this is totally successful, in a very small frame of testing. So if you are in agreeance that this method is a viable, stable and robust long-term option to store moderately large files (1kb to couple hundred megs), and large quantities of these files, let me know what other considerations or ideas you have. Also, I am considering getting a current "File Management" PHP script that gives an interface for managing files stored in the File System and converting it to manage files stored in the database. If there is already any software out there that does this, please let me know. I guess there are many questions I could ask, and all the information is up there ^^ so please, discuss all aspects of this and we can pass ideas back and forth and teach each other. Cheers, Quantico773

• Images missing after moving Django to new server

  - by miszczu

  I'm moving Django project to new server. I'm newbie in Django, and I don't know where should be upload folder. There are all images which should be displayed on website. In config file I haven't seen upload folder I could specify, so I'm guessing it always should be the same location for django projects or I just can't find it. Locations are saved in database. When I've put uploaded files into media folder, so url was like domain.co.uk/media/upload/media/images/year/month/day/image_name.ext and the same is on the old website, images on website ware still missing. All images are visible if I put url by hand, but django doesn't seems to see files. Also I check django log file: 2012-05-30 09:13:33,393 ERROR render: Thumbnail tag failed: [in /usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py (line 49)] Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py", line 45, in render return self._render(context) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py", line 97, in _render file_, geometry, **options File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/base.py", line 50, in get_thumbnail cached = default.kvstore.get(thumbnail) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/base.py", line 25, in get return self._get(image_file.key) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/base.py", line 123, in _get value = self._get_raw(add_prefix(key, identity)) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/cached_db_kvstore.py", line 26, in _get_raw value = KVStoreModel.objects.get(key=key).value File "/usr/lib/python2.6/site-packages/django/db/models/manager.py", line 132, in get return self.get_query_set().get(*args, **kwargs) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 344, in get num = len(clone) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 82, in __len__ self._result_cache = list(self.iterator()) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 273, in iterator for row in compiler.results_iter(): File "/usr/lib/python2.6/site-packages/django/db/models/sql/compiler.py", line 680, in results_iter for rows in self.execute_sql(MULTI): File "/usr/lib/python2.6/site-packages/django/db/models/sql/compiler.py", line 735, in execute_sql cursor.execute(sql, params) File "/usr/lib/python2.6/site-packages/django/db/backends/util.py", line 34, in execute return self.cursor.execute(sql, params) File "/usr/lib/python2.6/site-packages/django/db/backends/mysql/base.py", line 86, in execute return self.cursor.execute(query, args) File "/usr/lib64/python2.6/site-packages/MySQLdb/cursors.py", line 174, in execute self.errorhandler(self, exc, value) File "/usr/lib64/python2.6/site-packages/MySQLdb/connections.py", line 36, in defaulterrorhandler raise errorclass, errorvalue DatabaseError: (1146, "Table 'thumbnail_kvstore' doesn't exist") 2012-05-30 09:13:33,396 DEBUG execute: (0.000) SELECT `freetext_freetext`.`id`, `freetext_freetext`.`key`, `freetext_freetext`.`content`, `freetext_freetext`.`active` FROM `freetext_freetext` WHERE (`freetext_freetext`.`active` = True AND `freetext_freetext`.`key` = office-closed-message ); args=(True, u'office-closed-message') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,399 DEBUG execute: (0.000) SELECT `menus_menu`.`id`, `menus_menu`.`name`, `menus_menu`.`slug`, `menus_menu`.`base_url`, `menus_menu`.`description`, `menus_menu`.`enabled` FROM `menus_menu` WHERE (`menus_menu`.`enabled` = True AND `menus_menu`.`slug` = about ); args=(True, u'about') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,401 DEBUG execute: (0.000) SELECT `menus_menuitem`.`id`, `menus_menuitem`.`menu_id`, `menus_menuitem`.`title`, `menus_menuitem`.`url`, `menus_menuitem`.`order` FROM `menus_menuitem` INNER JOIN `menus_menu` ON (`menus_menuitem`.`menu_id` = `menus_menu`.`id`) WHERE `menus_menu`.`slug` = about ORDER BY `menus_menuitem`.`order` ASC; args=(u'about',) [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,404 DEBUG execute: (0.000) SELECT `freetext_freetext`.`id`, `freetext_freetext`.`key`, `freetext_freetext`.`content`, `freetext_freetext`.`active` FROM `freetext_freetext` WHERE (`freetext_freetext`.`active` = True AND `freetext_freetext`.`key` = contactdetails-footer ); args=(True, u'contactdetails-footer') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] I checked database and there is no table calls thumbnail_kvstore, but I have database backup, and in backup files this table doesn't exist.

• Django: CharField with fixed length, how?

  - by Giovanni Di Milia

  Hi everybody, I wold like to have in my model a CharField with fixed length. In other words I want that only a specified length is valid. I tried to do something like volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) but it gives me an error (it seems that I can use both max_length and min_length at the same time). Is there another quick way? Thanks EDIT: Following the suggestions of some people I will be a bit more specific: My model is this: class Volume(models.Model): vid = models.AutoField(primary_key=True) jid = models.ForeignKey(Journals, db_column='jid', null=True, verbose_name = "Journal") volumenumber = models.CharField('Volume Number') date_publication = models.CharField('Date of Publication', max_length=6, blank=True) class Meta: db_table = u'volume' verbose_name = "Volume" ordering = ['jid', 'volumenumber'] unique_together = ('jid', 'volumenumber') def __unicode__(self): return (str(self.jid) + ' - ' + str(self.volumenumber)) What I want is that the volumenumber must be exactly 4 characters. I.E. if someone insert '4b' django gives an error because it expects a string of 4 characters. So I tried with volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) but it gives me this error: Validating models... Unhandled exception in thread started by <function inner_run at 0x70feb0> Traceback (most recent call last): File "/Library/Python/2.5/site-packages/django/core/management/commands/runserver.py", line 48, in inner_run self.validate(display_num_errors=True) File "/Library/Python/2.5/site-packages/django/core/management/base.py", line 249, in validate num_errors = get_validation_errors(s, app) File "/Library/Python/2.5/site-packages/django/core/management/validation.py", line 28, in get_validation_errors for (app_name, error) in get_app_errors().items(): File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 131, in get_app_errors self._populate() File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 58, in _populate self.load_app(app_name, True) File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 74, in load_app models = import_module('.models', app_name) File "/Library/Python/2.5/site-packages/django/utils/importlib.py", line 35, in import_module __import__(name) File "/Users/Giovanni/src/djangoTestSite/../djangoTestSite/journaldb/models.py", line 120, in <module> class Volume(models.Model): File "/Users/Giovanni/src/djangoTestSite/../djangoTestSite/journaldb/models.py", line 123, in Volume volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) TypeError: __init__() got an unexpected keyword argument 'min_length' That obviously doesn't appear if I use only "max_length" OR "min_length". I read the documentation on the django web site and it seems that I'm right (I cannot use both together) so I'm asking if there is another way to solve the problem. Thanks again

• Accessing Content from MDF after attached to SQL

  - by Fidelis

  Hello, I am using WSS 3.0 and trying to restore a mdf. I attached the database in SQL Management Studio, created a new web application, and associated the database to it. When I go into Central Administration- Application Management - Content Databases I see the WSS_Content and it says Sites: 2. One of the sites looks more similar to the other. I was able to log into the Sharepoint web app that has the db attached to it, and while it gives me the basic structure of the backed up site, the content of lists is blank, that was the data I was really after (Announcements, tasks, etc exist as lists but are empty). How do I get access to this?

• odd problem with jni interacting with dll's - not sure why a change to gc ergonomics fixes it

  - by jim hale

  We were having a problem with our Tomcat jvm blowing up and giving us an hs_* dump at random times but always in the same spot, that wasn't very informative other than saying we had an EXCEPTION_ACCESS_VIOLATION Commenting out various parts of the java that called particular jni functions just made it blow consistently in another spot. By changing our jvm options from: set PAF_OPTS=-Xms1024m -Xmx32000m -server -XX:+UseParallelGC -XX:+UseParallelOldGC -XX:+DisableExplicitGC -XX:+UseCompressedOops -Djava.library.path="%CATALINA_HOME%"\jni -Dcom.sun.management.jmxremote TO set PAF_OPTS=-Xms1024m -Xmx32000m -server -XX:+DisableExplicitGC -XX:+UseCompressedOops -Djava.library.path="%CATALINA_HOME%"\jni -Dcom.sun.management.jmxremote The problem went away. The solution does not give me a warm and fuzzy however and am wondering anyone might understand what's going on under the covers here. Environment: jdk1.6, 64 bit OS and Java, Tomcat, Windows

• what special issues are at play when loading a config file from the comand prompt with DTExec

  - by Ralph Shillington

  If I run a package from the Management Studio, and specify a configuration file, everything works as expected. However if I try and run the package from the command prompt with DTExec I get the error: Cannot load the XML configuration file. The XML configuration file may be malformed or not valid. The command I'm using to execute the package is: dtexec /conf ConfigurationDemo.dtsConfig /f Package.dtsx I am running the dtexec from the folder where these two files reside. Is there an addtional switch or something that must used to get dtexec to behave the same was at the management Stduio in launching a package?

• springTestContextBeforeTestMethod failed in Maven spring-test

  - by joejax

  I try to setup a project with spring-test using TestNg in Maven. The code is like: @ContextConfiguration(locations={"test-context.xml"}) public class AppTest extends AbstractTestNGSpringContextTests { @Test public void testApp() { assert true; } } A test-context.xml simply defined a bean: <bean id="app" class="org.sonatype.mavenbook.simple.App"/> I got error for Failed to load ApplicationContext when running mvn test from command line, seems it cannot find the test-context.xml file; however, I can get it run correctly inside Eclipse (with TestNg plugin). So, test-context.xml is under src/test/resources/, how do I indicate this in the pom.xml so that 'mvn test' command will work? Thanks, UPDATE: Thanks for the reply. Cannot load context file error was caused by I moved the file arround in different location since I though the classpath was the problem. Now I found the context file seems loaded from the Maven output, but the test is failed: Running TestSuite May 25, 2010 9:55:13 AM org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions INFO: Loading XML bean definitions from class path resource [test-context.xml] May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext prepareRefresh INFO: Refreshing org.springframework.context.support.GenericApplicationContext@171bbc9: display name [org.springframework.context.support.GenericApplicationContext@171bbc9]; startup date [Tue May 25 09:55:13 PDT 2010]; root of context hierarchy May 25, 2010 9:55:13 AM org.springframework.context.support.AbstractApplicationContext obtainFreshBeanFactory INFO: Bean factory for application context [org.springframework.context.support.GenericApplicationContext@171bbc9]: org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99 May 25, 2010 9:55:13 AM org.springframework.beans.factory.support.DefaultListableBeanFactory preInstantiateSingletons INFO: Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@1df8b99: defining beans [app,org.springframework.context.annotation.internalCommonAnnotationProcessor,org.springframework.context.annotation.internalAutowiredAnnotationProcessor,org.springframework.context.annotation.internalRequiredAnnotationProcessor]; root of factory hierarchy Tests run: 3, Failures: 2, Errors: 0, Skipped: 1, Time elapsed: 0.63 sec <<< FAILURE!

UPDATE: I think I got the problem (still don't know why) - Whenever I extends AbstractTestNGSpringContextTests or AbstractTransactionalTestNGSpringContextTests, the test will failed with this error: Failed tests: springTestContextBeforeTestMethod(org.sonatype.mavenbook.simple.AppTest) springTestContextAfterTestMethod(org.sonatype.mavenbook.simple.AppTest) So, eventually the error went away when I override the two methods. I don't think this is the right way, didn't find much info from spring-test doc. If you know spring test framework, please shred some light on this.

• Singleton again, but with multi-thread and Objective-C

  - by Tonny Xu

  I know Singleton pattern has been discussed so much. But because I'm not fully understand the memory management mechanism in Objective-C, so when I combined Singleton implementation with multithreading, I got a big error and cost me a whole day to resolve it. I had a singleton object, let's call it ObjectX. I declared an object inside ObjectX that will detach a new thread, let's call that object objectWillSpawnNewThread, when I called [[ObjectX sharedInstance].objectWillSpawnNewThread startNewThread]; The new thread could not be executed correctly, and finally I found out that I should not declare the object objectWillSpawnNewThread inside the singleton class. Here are my questions: How does Objective-C allocate static object in the memory? Where does Objective-C allocate them(Main thread stack or somewhere else)? Why would it be failed if we spawn a new thread inside the singleton object? I had searched the Objective-C language [ObjC.pdf] and Objective-C memory management document, maybe I missed something, but I currently I could not find any helpful information.

• Documenting user scenarios and measuring/testing

  - by Rimian

  Please forgive me as I don't quite remember the exact terms for what I am talking about... hence my question. Recently I worked on a large Agile team where I encountered a method of defining user scenarios (much like user stories). These scenarios were a few very basic short sentences with keywords and a structure that could be understood by humans (especially project managers) and could also be coded against using some Java Framework (for verifying tests). The exact structure of this mini language used keywords like "when" and "and" or "if" which was how the framework parsed and verified the result. The purpose of this framework was to interface between management and the acceptance testing framework. So essentially management could write the tests themselves using English. The scenario went something like this: "When a user visits URL and User clicks on X Something happens (that can be measured)" Can anyone help me remember exactly what I am talking about? Many thanks

• errors deploying an EAR with EJBs 2.1 into JBoss AS5

  - by Marina

  Hi, I'm porting an application with EJBs 2.1 from Weblogic9 to JBoss AS5. I have made some of the changes like adding jboss.xml descriptors to EJBs and fixing application.xml of the EAR, but there are still problems when deploying the EAR. Here is a summary of the the latest error I'm getting when the first EJB is being deployed by JBoss (I will add the full stack trace at the end of the message): 14:15:48,124 ERROR [AbstractKernelController] Error installing to Parse: name=vf sfile:/C:/Marina/Tools/jboss-5.1.0.GA/server/default/deploy/contracts.ear/ state =Not Installed mode=Manual requiredState=Parse org.jboss.deployers.spi.DeploymentException: Error creating managed object for v fsfile:/C:/Marina/Tools/jboss-5.1.0.GA/server/default/deploy/contracts.ear/admin -ejb.jar/ ....

• Life Cycle Tools Suite

  - by pearcewg

  I am looking to replace the life cycle tools currently used by my development teams. Tools that I'm looking for: Version Control Defect/Issue Tracking Requirements Tracking Test Case Management (potentially) Project Management: Project Status, hours entry I have a new beefy server (Windows 2008 Server) to run all tools on. I'm looking at COTS and Open Source options, but haven't decided so far. Other factors: Distributed team (different physical sites) Some Windows Development, some Linux Development Software, Firmware, Technical Writing need to be able to use it Recommendations on a good suite that will work together? If Open Source, best approach to run on the Windows 2008 Server?

• Mixing inheritance mapping strategies in NHibernate

  - by MylesRip

  I have a rather large inheritance hierarchy in which some of the subclasses add very little and others add quite a bit. I don't want to map the entire hierarchy using either "table per class hierarchy" or "table per subclass" due to the size and complexity of the hierarchy. Ideally I'd like to mix mapping strategies such that portions of the hierarchy where the subclasses add very little are combined into a common table a la "table per class hierarchy" and subclasses that add a lot are broken out into a separate table. Using this approach, I would expect to have 2 or 3 tables with very little wasted space instead of either 1 table with lots of fields that don't apply to most of the objects, or 20+ tables, several of which would have only a couple of columns. In the NHibernate Reference Documentation version 2.1.0, I found section 8.1.4 "Mixing table per class hierarchy with table per subclass". This approach switches strategies partway down the hierarchy by using: ... <subclass ...> <join ...> <property ...> ... </join> </subclass> ... This is great in theory. In practice, though, I found that the schema was too restrictive in what was allowed inside the "join" element for me to be able to accomplish what I needed. Here is the related part of the schema definition: <xs:element name="join"> <xs:complexType> <xs:sequence> <xs:element ref="subselect" minOccurs="0" /> <xs:element ref="comment" minOccurs="0" /> <xs:element ref="key" /> <xs:choice minOccurs="0" maxOccurs="unbounded"> <xs:element ref="property" /> <xs:element ref="many-to-one" /> <xs:element ref="component" /> <xs:element ref="dynamic-component" /> <xs:element ref="any" /> <xs:element ref="map" /> <xs:element ref="set" /> <xs:element ref="list" /> <xs:element ref="bag" /> <xs:element ref="idbag" /> <xs:element ref="array" /> <xs:element ref="primitive-array" /> </xs:choice> <xs:element ref="sql-insert" minOccurs="0" /> <xs:element ref="sql-update" minOccurs="0" /> <xs:element ref="sql-delete" minOccurs="0" /> </xs:sequence> <xs:attribute name="table" use="required" type="xs:string" /> <xs:attribute name="schema" type="xs:string" /> <xs:attribute name="catalog" type="xs:string" /> <xs:attribute name="subselect" type="xs:string" /> <xs:attribute name="fetch" default="join"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="join" /> <xs:enumeration value="select" /> </xs:restriction> </xs:simpleType> </xs:attribute> <xs:attribute name="inverse" default="false" type="xs:boolean"> </xs:attribute> <xs:attribute name="optional" default="false" type="xs:boolean"> </xs:attribute> </xs:complexType> </xs:element> As you can see, this allows the use of "property" child elements or "component" child elements, but not both. It also doesn't allow for "subclass" child elements to continue the hierarchy below the point at which the strategy was changed. Is there a way to accomplish this?

• Problem using SQLDMO/Vb6 against SQL Server 2008

  - by E.J. Brennan

  I have a client, that uses SQLDMO for a portion of a custom application that was written against SQL Server 2000, and they recently upgraded to SQL Server 2008. The majority of the app still runs fine (doesn't use SQLDMO), but the admin functions which rely on SQLDMO stopped working. I installed the SQL2005 backward compatibility pack, and now SQLDMO partially works, i.e. I can run "select" type queries, but any "Update" queries fail with the error message: to connect to the server you must use SQL Server management studio or sql server management objects (SMO) Any thoughts? Should the backward compatibility pack give me ALL the functionality back, or is this a known issue? BTW: I realize SQLDMO has been deprecated and will go away next release, none-the-less I need to do what I can to solve the problem at hand.

• AD-Integrated DNS failure: "Access was Denied"

  - by goldPseudo

  I have a single Windows 2008 R2 server configured as a domain controller with Active Directory Domain Services and DNS Server. The DNS Server was recently uninstalled and reinstalled in an attempt to fix a (possibly unrelated) problem; the event log was previously flooded with errors (#4000, "The DNS Server was unable to open Active Directory...") which reinstalling did not fix. However, while before it was at least showing and resolving names from the local network (slowly), now it's showing nothing at all. (The original error started with a #4015 error "The DNS server has encountered a critical error from the Active Directory," followed by a long string of #4000 and a few #4004. This may have been caused when a new DNS name was recently added, but I can't be sure of the timing.) Attempting to manage the DNS through Administrative Tools > DNS brings up an error: The server SERVERNAME could not be contacted. The error was: Access was denied. Would you like to add it anyway? Selecting yes just puts a SERVERNAME item on the list, but with all the configuration options grayed out. I attempted editing my hosts file as per this post but to no avail. Running dcdiag, it does identify the home server properly, but fails right away testing connectivity with: Starting test: Connectivity The host blahblahblahyaddayaddayadda could not be resolved to an IP address. Check the DNS server, DHCP, server name, etc. Got error while checking LDAP and RPC connectivity. Please check your firewall settings. ......................... SERVERNAME failed test Connectivity Adding the blahblahblahyaddayaddayadda address to hosts (pointing at 127.0.0.1), the connectivity test succeeded but it didn't seem to solve the fundamental problem (Access was denied) so I hashed it out again. Primary DNS server is properly pointing at 127.0.0.1 according to ipconfig /all. And the DNS server is forwarding requests to external addresses properly (if slowly), but the resolving of local network names is borked. The DNS database itself is small enough that I am (grudgingly) able to rebuild it if need be, but the DNS Server doesn't seem willing to let me work with (or around) it at all. (and yes before you ask there are no system backups available) Where do I go from here? As requested, my (slightly obfuscated) dcdiag output: Directory Server Diagnosis Performing initial setup: Trying to find home server... Home Server = bulgogi * Identified AD Forest. Done gathering initial info.

• Lock Free Queue -- Single Producer, Multiple Consumers

  - by Shirish

  Hello, I am looking for a method to implement lock-free queue data structure that supports single producer, and multiple consumers. I have looked at the classic method by Maged Michael and Michael Scott (1996) but their version uses linked lists. I would like an implementation that makes use of bounded circular buffer. Something that uses atomic variables? On a side note, I am not sure why these classic methods are designed for linked lists that require a lot of dynamic memory management. In a multi-threaded program, all memory management routines are serialized. Aren't we defeating the benefits of lock-free methods by using them in conjunction with dynamic data structures? I am trying to code this in C/C++ using pthread library on a Intel 64-bit architecture. Thank you, Shirish

• zend_form ViewScript decorator / passing arguments

  - by timpone

  I have a form that is extend from Zend_Form. I am placing the form into a ViewScript decorator like this: $this->setDecorators(array(array('ViewScript', array('viewScript' => 'game/forms/game-management.phtml')))); I'd like to pass in a variable to this ViewScript but am not sure how this could be done. Since the partial renders out as a Zend_View (allowing $this-app_store_icon for rendering), it seems like there should be a way to pass variables to be rendered. I tried the following but to no avail. $this->setDecorators(array(array('ViewScript', array('viewScript' => 'game/forms/game-management.phtml'),array('app_store_picon'=>$current_app_store_picon)))); Any help on how to get this done would be appreciated. thanks
