  • Did the OS X java update to 1.5u7 whack my 1.6.0 laf.jar?

    - by Brian Deacon
    This is the update that just came out this week (2010-05-18) Somebody moved my cheese. It appears that laf.jar is Look And Feel, so probably not a big deal for my java development. Eclipse got mad about the missing jar, and furthermore thinks the 1.6.0 VM disappeared, which it didn't. Had to redefine the VM library within eclipse and everything appears kosher, but was hoping somebody with more hit points than me could say so definitively. Am I all good? Was it really the OSX update for 1.5 that went and hunted down a file in my 1.6 VM? Haven't been able to google anything about this... if somebody could post a link to some info about this, that'd be appreciated too.

  • I get "stack level too deep" error when using a named scope

    - by Brian Roisentul
    I'm using ruby on rails 2.3.8 and when I write the syntax shown below I get the "stack level too deep" error message. The model is called Announcement and the line of the error looks like this: Tag.find(category_id).announcements.published Where published is named_scope :published, :conditions => "announcements.state = 'published'" I use this named scope in many other places and it works fine. What am I doing wrong? (the relationship between Tag and Announcement model is ok because if I remove the ".published" method from that line it works just fine).

  • Scanner's Read Line returning NoSuchElementException

    - by Brian
    This is my first time using StackOverflow. I am trying to read a text file which consists of a single number one the first line. try { Scanner s = new Scanner(new File("HighScores.txt")); int temp =Integer.parseInt(s.nextLine()); s.close(); return temp; } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } However, I get an error: java.util.NoSuchElementException: No line found at java.util.Scanner.nextLine(Unknown Source) at GameStart.getHighScore(GameStart.java:334) at GameStart.init(GameStart.java:82) at sun.applet.AppletPanel.run(Unknown Source) at java.lang.Thread.run(Unknown Source) I know that HighScores.txt is not empty, so why is this problem occuring? I tried using BufferedReader, and BufferReader.readLine() return null.

  • JSP Iterating over a map of a list when the value might be null

    - by Brian Hoover
    How do I clear the value from the stack of a s:iterator? I'm trying to iterator over a TreeMultimap with a structure like: TreeMultimap<person, lineItems> persons; Using something like: <s:iterator value="attendeesForParticipantTypeEvents.asMap()"> <div> <s:property value="key.name" /><br /> <s:iterator id="currentSku" value="value"> <s:property value="currentSku.name" /><br /> </s:iterator> </div> </s:iterator> This works fine, except when the treeMultimap has null for lineItems, then it's taking the value from the previous iteration. So, a structure like: persons = {{"Person1",["Line1","line2"]}, {"Person2",["Line3","line4"]}, {"Person2",null}} Renders as: <div> Person1<br /> Line1<br /> Line2<br /> </div> <div> Person2<br /> Line3<br /> Line4<br /> </div> <div> Person3<br /> Line3<br /> Line4<br /> </div> Which seems to indicate that the value isn't being cleared on each iterator. What do I need to do to handle the case where value might be null? Thanks for your help

  • iphone threading speed up startup of app

    - by BahaiResearch.com
    I have an app that must get data from the Sqlite database in order to display the first element to the User. I have created a domain object which wraps the DB access and is a thread safe singleton. Is this following strategy optimal to ensure the fastest load given the iPhone's file access and memory management capabilities in threaded apps: 1) In the AppDelegate's FinishedLaunching event the very first thing I do is create the domain singleton within a new thread. This will cause the domain object to go to Sqlite and get the data it needs without locking the UI thread. 2) I then call the standard Window methods to add the View and MakeKeyAndVisible etc. Is there an earlier stage in the AppDelegate where I should fire off the thread that creates the Domain Object and accesses Sqlite?

  • Mysql Master Slave Replication on Large Database table (how to sync initial data)

    - by Brian Lovett
    We have a production server and a dev server. We have found that backups are nearly impossible on the production server because of the query volume we experience. So, we're looking at setting up replication with our dev server being the slave. This is ideal because we can afford to lock the tables on that server and additionally it will be nice to have up to date data for the developers. Now, the issues. The production server can't really be taken down or locked at this point, at least not easily. We have a high query volume and fairly large 30+ GB innodb tables. Both servers are running all innodb and are also both on mysql 5.1. What can we do to sync the data initially to get replication started? I've tried a few options, but so far, none have worked.

  • Proper thread termination in multi-threaded C# application

    - by Brian
    I have what I think is a rather complex problem. I have a C# application that utilizes a plug-in architecture using reflection. The application loads plug-in dlls and the user is able to enable/disable them. When a plug-in is enabled, the main app starts a thread to run the plug-in in. In many cases the plug-in may have multiple threads of its own. When I want to disable a plug-in I am calling Thread.Abort(). This seems to kill the initial thread that was created for the plug-in, but any additional threads that the plug-in created continue running. Is there a better way to stop all of the associated plug-in's threads along with the main thread? Thanks.

  • jpa join query on a subclass

    - by Brian
    I have the following relationships in JPA (hibernate). Object X has two subclasses, Y and Z. Object A has a manyToOne relationship to object X. (Note, this is a one-sided relationship so object X cannot see object A). Now, I want to get the max value of a column in object A, but only where the relationship is of a specific subtype, ie...Y. So, that equates to...get the max value of column1 in object A, across all instances of A where they have a relationship with Y. Is this possible? I'm a bit lost as how to query it. I was thinking of something like: String query = "SELECT MAX(a.columnName) FROM A a join a.x; Query query = super.entityManager.createQuery(query); query.execute(); However that doesn't take account of the subclass of X...so I'm a bit lost. Any help would be much appreciated.

  • Any recommended VC++ settings for better PDB analysis on release builds

    - by Brian R. Bondy
    Are there any VC++ settings I should know about to generate better PDB files that contain more information? I have a crash dump analysis system in place based on the project crashrpt. Also, my production build server has the source code installed on the D:\, but my development machine has the source code on the C:\. I entered the source path in the VC++ settings, but when looking through the call stack of a crash, it doesn't automatically jump to my source code. I believe if I had my dev machine's source code on the D:\ it would work.

  • Modifying the Codec List Object in an ASF file

    - by scompt.com
    Is it possible to modify the Codec List Object in an ASF file? In particular, I would like to edit the codec name and description. I realize that this won't actually change the content of the video, but it's necessary for the video to be verified by an external tool. Does anyone know of a tool that will allow me to do this? If not, does anyone have any suggestions about how I might go about doing it using the Windows Media Format 11 SDK?

  • Tortoisesvn using svn:mergeinfo, is there a way to turn it off?

    - by Brian R. Bondy
    When I'm doing a tortoise svn merge, it includes a bunch of directories, and some files into the modified files, even know there are no actual changes. It changes the property svn:mergeinfo Is there any reason why these properties set on the directory/files are needed? Is there any way to get around not doing these changes to svn:mergeinfo? I usually just revert the items then commit, but this wastes extra time

  • What time/date do you stamp your deployed data/exe files when they appear on the target system?

    - by Brian Frost
    It seems a good and clean thing to ensure that your deployed files appear on the target system with a consistent time/date. Many Applications seem to do this but other than for care of overwriting Users' existing data I guess it has no real significance. I'm having a purge on my installer packaging and I'd like to know if there any good reasons for specific date/time handling.

  • Python breaks for a certain amount

    - by Brian Cox
    All, I am not very good at explaining so i will let my comments do it! #this script is to calculate some of the times table up to 24X24 and also miss some out #Range of numbers to be calculated numbers=range(1,25) for i in numbers: for w in numbers: print(str(i)+"X"+str(w)+"="+str(i*w)) #here i want to break randomly (skip some out) e.g. i could be doing the 12X1,12X2 and then 12X5 i have no limit of skips. Update Sorry if this is not clear i want it to break from the inner loop for a random amount of times

  • Write/read count to txt file

    - by Brian
    Hi, I need a batch file that writes the count number to a txt file. Next time the batch file is run, it should read the current count number from the txt file and add 1 to count and save this new value in the txt file. (nothing else is in the txt file) When count is 5 it should start from 1 again Example: Count.bat runs 1 time: count.txt has no count so Count.bat saves the value 1 in count.txt Count.bat is run 2 time: Count.bat reads 1 from count.txt and saves the new value 2 to count.txt When count.bat is run for the 6 time it should start over by saving the value 1 in count.txt I think this just be easy to do, but I'am not use to batch commands So hopefully someone here could help me.

  • Prevent browser form submission when Wicket AjaxFormValidatingBehaviour validation fails

    - by Brian Laframboise
    I have a Page with a Wizard component. The user can navigate the panels of the wizard by using the next and previous buttons which I have performing full (non-ajax) form submissions so that the app is back-button friendly. When the next button is clicked, I would like to attempt ajax form validation (if javascript is enabled). I tried doing: nextButton.add( new AjaxFormValidatingBehavior( form, "onsubmit") ); to add such validation. The behaviour works - however, when validation errors occur the browser still submits the entire form. What is the Wicket way to prevent the browser from submitting the form in this case?

  • How to update attributes without valitation

    - by Brian Roisentul
    I've got a model with its validations, and I found out that I can't update an attribute without validating the object before. I already tried to add on => :create syntax at the end of each validation line, but I got the same results. My announcement model have the following validations: validates_presence_of :title validates_presence_of :description validates_presence_of :announcement_type_id validate :validates_publication_date validate :validates_start_date validate :validates_start_end_dates validate :validates_category validate :validates_province validates_length_of :title, :in => 6..255, :on => :save validates_length_of :subtitle, :in => 0..255, :on => :save validates_length_of :subtitle, :in => 0..255, :on => :save validates_length_of :place, :in => 0..50, :on => :save validates_numericality_of :vacants, :greater_than_or_equal_to => 0, :only_integer => true validates_numericality_of :price, :greater_than_or_equal_to => 0, :only_integer => true My rake task does the following: task :announcements_expiration => :environment do announcements = Announcement.expired announcements.each do |a| #Gets the user that owns the announcement user = User.find(a.user_id) puts a.title + '...' a.state = 'deactivated' if a.update_attributes(:state => a.state) puts 'state changed to deactivated' else a.errors.each do |e| puts e end end end This throws all the validation exceptions for that model, in the output. Does anybody how to update an attribute without validating the model?

  • How can I force a subscriber to be synchronized from a local snapshot?

    - by Brian
    Hello, I have a SQL 2005 server replicating(merge\push) to SQL 2005 and SQL 2000 servers. I have multiple subscribers spread througout the United states. I have set , @snapshot_in_defaultfolder = N'false', @alt_snapshot_folder = N'c:\snapshots\Merge\' (sample location). I take the snapshot from the publisher that is in the same location, 'c:\snapshots\Merge\', and copy it to the subscribers. I wanted to avoid applying the snapshot over the WAN but from the performance I am getting the synchronization is going over the WAN. Does anybody have any ideas how to make sure that I am using the local copy of the snapshot and not the copy at the publisher? Thanks
