• Save application preferences... registry/file?

  - by spender

  Where is the best place to store application preferences? In particular, I'd like to save preferences for a media player such as volume levels and the like. Two candidates spring to mind... file and registry. Which would be more appropriate? As a follow up to this, I'm also wondering if there are any APIs that aid in creating application specific settings. Unless someone advises me that this is wrong, I'd like to save stuff either in HKCU... or HKLM/Software/MyCompanyName/MyAppName/Key for the registry, or in %APPDATA\MyCompanyName\MyAppName\someTypeOfSettingsFile. As these seem to be commonly used for such settings, I'd assume that .Net makes it easy to store settings in these locations. Is there a simple high level API that can .Net offer me to read and write settings to these common locations?

• Is the offical Sun Java EE tutorial the best way to learn how to make Java web apps?

  - by Nick

  I've been a web developer for almost a decade. I've mostly used classic ASP/JavaScript and I'd like to move into Java based apps. I have a decent understanding of Java itself (enough to know how to lookup what I don't know) and I spent some time doing minor work on a JSF/Spring/Hibernate app, but from what a trusted coworker told me, this application is the example of what not to do. I want to learn the really hardcore stuff (EJBs, HA Clustering, etc), but I know I have to walk before I can run. Is the Sun Tutorial the best place to start? Or is there an definitive book (like K&R for C or Gang of Four for design patterns) that I should buy?

• FileNotFound exception

  - by Pratik

  I am trying to read a file in a servlet. I am using eclipse IDE. I get a FileNotFoundException if I provide relative file name. List<String> ls=new ArrayList<String>(); Scanner input = new Scanner(new File("Input.txt")); while(input.hasNextLine()) { ls.add(input.nextLine()); } The same code works if I put the absolute path like this: Scanner input = new Scanner(new File("F:/Spring and other stuff/AjaxDemo/src/com/pdd/ajax/Input.txt")); The Java file and text file are there in the same folder. Does it searches text file in some other folder ?

• deleting a large number of rows from a table

  - by Azeem

  We have a requirement to delete rows in the order of millions from multiple tables as a batch job (note that we are not deleting all the rows, we are deleting based on a timestamp stored in an indexed column). Obviously a normal DELETE takes forever (because of logging, referential constraint checking etc.). I know in the LUW world, we have ALTER TABLE NOT LOGGED INITIALLY but I can't seem to find the an equivalent SQL statement for DB2 v8 z/OS. Any one has any ideas on how to do this really fast? Also, any ideas on how to avoid the referential checks when deleting the rows? Please let me know.

• Large number of tables and Hibernate memory consumption

  - by Vedran

  I'm working on a large ERP project which has database model with about 2100 tables. With "only" 500 tables mapped with Hibernate, application deployed on the web server takes about 3GB of working memory. Is there any way to reduce Hibernate's metamodel memory footprint when using that many tables in one persistence unit? Or should I just give up on ORMs and go with plain old JDBC (or even jOOQ)? Right now I'm using Hibernate 4.1.8, Spring 3.1.3, JBoss AS 7.1 and working with MSSQL database. Edit: JavaMelody memory histogram output - with 2000 generated test tables that are a bit smaller in scope from the original db model (hence 'only' 1.3GB of spent memory)

• Java training for .NET developers?

  - by C Keene

  We are working with a large retail bank on training 40-50 .Net developers to use Java. They are familiar with C# and .Net framework and have built dozens of "run the business" style apps in .Net. We need advice on how to provide basic Java familiarity, with a focus on back end logic, security and transaction management. Back end is Spring/Hibernate, front end is Ajax (Dojo). Are there any online, self-paced, Java courses that would be good for C#/.Net developers to get up to speed quickly?

• How do I get the Bake console for CakePHP?

  - by ggfan

  I am having trouble getting the Bake console. I am on windows running xampp. I'm doing the IBM cakphp tutorial. Here is my directory: C:\\ xampp htdocs ibm2(a test project--orginally called cakephp) app cake vendors (etc) It says to To use Bake, cd into the /webroot/app directory and launch the Cake Console: ../cake/console/cake bake. You should be presented with a screen that looks like Figure 2. So I write in my command prompt till I am at: C:\xampp\htdocs\ibm2\app Then I type ../cake/console/cake bake but I get this error: '..' is not recognized as an internal or external command, operable program or batch file. What am I doing wrong? I use the window's command prompt

• In a pre-commit hook - how to access/compare current and previous versions of files

  - by EthanML

  I'm trying to add to our existing pre-commit SVN hook so that it will check for and block an increase in file size for files in specific directory/s. I've written a python script to compare two file sizes, which takes two files as arguments and uses sys.exit(0) or (1) to return the result, this part seems to work fine. My problem is in calling the python script from the batch file, how to reference the newly committed and previous versions of each file? The existing code is new to me and a mess of %REPOS%, %TXN%s etc and I'm not sure how to go about using them. Is there a simple, standard way of doing this? It also already contains code to loop through the changed files using svnlook changed, so that part shouldn't be an issue. Thanks very much

• php convert images and upload to amazon s3

  - by faraklit

  I am looking for a best practice while uploading images to amazon s3 server and serving from there. We need four different sizes of an image. So just after image upload we convert the image and scale in 4 different widths and heights. And then we send them to the amazon s3 using official php api. // ... // image conversions, bucket setting, s3 initialization etc. $sizes= array("", "48", "64", "128"); foreach($sizes as $size) { $filename = $upload_path.$dest_file.$size.$ext; $s3->batch()->create_object($bucket, , array( 'fileUpload' => $filename, 'acl' => AmazonS3::ACL_PUBLIC, )); } But for a 1M image the client sometimes wait up to 30 seconds which is a very long time. Instead of sending images immediately to S3, it may be better to add them to a job queue. But the user should see the uploaded image immediately.

• OS monitoring using JAVA

  - by Puneri

  I'm planning to implement a framework for monitoring OS level resources: process network stats cpu info etc using JAVA. I see there is SIGAR API by Spring, which is implemented in native language and JAVA API being provided on top. But I will prefer not to have native stuff in my framework, rather for each OS will write a Java Class which will fetch required OS info by running system commands via JAVA Runtime. So I would like to have inputs/suggestions that one may have seen of not doing this in JAVA and use native app/api/jni. Any example will help for sure. I agree each OS has different commands to get these stats, but will prefer to have a Java Class per OS than have/load native code.

• Server-side Audio Editor

  - by Kristen

  I am looking for an audio editor that we can use server side (ASP + IIS) We want users to be able to upload an audio file, and then offer a 10 second teaser clip to other users for download. Ideally I would like our application to be able to specify Input and Output Filename, Start and End time (or Duration), and be able to fade-in and fade-out, and equalise the volume. Maybe some audio editors have a batch edit facility, and it would just be a question of installing on the server? All the keywords I have tried putting into Google have led me on a wild goose chase, hopefully someone can help me with suggestions. Thanks.

• Rails- MiniMagick commands not working

  - by digitalWestie

  I'm running windows xp and I've got MiniMagick and ImageMagick installed (latest versions). I'm now using the console to test out that everything works. Using the ms command prompt image magick works no problem. I'm testing this by using the identify command. Now, when I try to use MiniMagick from the console by entering image = MiniMagick::Image.new('image.jpg') It returns MiniMagickError, "ImageMagick command ("identify \"input.jpg\"") failed: {:status_code = #"'identify' is not recognized as an internal or external command,\noperable program or batch file.\n"} Can anybody help?

• How to identify deadlock conditions in a third-party application?

  - by Imhotep is Invisible

  I am using a third-party application to handle batch CD audio extraction via multiple FireWire attached devices, but the application frequently (though non-deterministically) hangs during the extraction. I suspect that the multithreaded application is deadlocking over some shared resource. The developer, however, suspects the problem lies elsewhere but is not addressing the problem at this time. I would like to be able to do some legwork on my end to a) prove the condition exists and b) ideally point him in the right direction. The problems: while I used to be a programmer, it's been awhile and I need to shake off the dust (last work I did was back in '99 and it was under Solaris, while the application runs under XP). Rather than there being a dearth of information online, there's almost too much to digest. Are there any suggested guides or tutorials that might help me get back up to speed sufficient enough to help identify and/or diagnose the deadlock, or are there tools or approaches that I should study up on to aid me in my task? Many thanks for all suggestions!

• Hudson's FindBugs plugin reports line number "-1" for bugs. Ideas?

  - by John B.

  Greetings, I have a simple test project set up in Hudson and the project's build process (a batch file) generates a findbugs.xml file. This is processed by Hudson's FindBugs plugin but it shows the line number of the bugs as "-1" instead of their actual line number. A coworker suggested I enable debug info for the compiler. I used the -g "Generate all debugging info" option for javac but nothing seemed to change. My build command is: javac -g -classpath C:\testWebApp1\src -d C:\testWebApp1\build C:\testWebApp1\src\*.java The only other thing in the build.bat file is a call to the FindBug tool (text UI). Here is what the FindBugs Plugin says about the first bug: File: GenerateHellos.java, Line: -1, Type: UUF_UNUSED_FIELD, Priority: Normal, Category: PERFORMANCE Any ideas? Thanks a ton!

• What web application is recommended when programming in Java for beginners?

  - by user1710260

  I am a beginner (almost no knowledge) to web applications. I have been programming in Java for about a year now. I have being doing some research on the different frameworks that are available and I want to find which one is right for me. From what I found: Play, Stripes, and Spring are good choices for beginners, but how can I compare these frameworks together. What is it that I need to look for when comparing them? My project that I am starting to work on is similar to an App Store. Basically an info site on different apps. Any advise will be appreciated.

• Is there any way to perform pre-/post-switch commands using TortoiseSVN?

  - by Steve

  We need to perform some tasks when switching from one Subversion branch to another using TortoiseSVN. Is there any way to, say, call a batch file before and after the switch? The only thing I can find are pre-/post-update and commit hooks, but none of those get executed when switching between branches. EDIT: I am looking for client-side hooks. TortoiseSVN has client-side hook scripts for pre-/post-update and commit, but nothing (that I can find) for pre-/post-switch. Initially, I thought adding hooks for client-side pre-/post-update would be executed when switching between branches, but this does not seem to be the case.

• Recordset Update errors when updating sql_variant field

  - by Stephen Nutt

  I'm using C++ and ADO to add data to a SQL Server 2005 database. When calling the Recordset Update method for a sql_variant column I'm getting the error DB_E_ERRORSOCCURRED and the error message Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done. If the value I'm adding is NULL all works fine and all values going to the fields that are not sql_variant types work. Does anyone know what I might be doing wrong? Thanks [Edit] I have some more information. The value we are storing is the empty string - ADO appears to want to store this in the sql_variant as a nchar(0), which of course is not a valid SQL data type. Is there a way to get an empty string in a sql_variant using the ADO batch commands?

• Azure Service Bus Scalability

  - by phebbar

  I am trying to understand how can I make Azure Service Bus Topic to be scaleable to handle 10,000 requests/second from more than 50 different clients. I found this article at Microsoft - http://msdn.microsoft.com/en-us/library/windowsazure/hh528527.aspx. This provides lot of good input to scale azure service bus like creating multiple message factories, sending and receiving asynchronously, doing batch send/receive. But all these input are from the publisher and subscriber client perspective. What if the node running the Topic can not handle the huge number of transactions? How do I monitor that? How do I have the Topic running on multiple nodes? Any input on that would be helpful. Also wondering if any one has done any capacity testing with Topic/Queue and I am eager to see those results... Thanks, Prasanna

• How to set up a different context to point to an external directory outside webapps Tomcat/Java

  - by pinkb

  Hi Folks, I am successful to map an external directory by creating an xml file like : <Context path="/uploads" docBase="C:\uploads\photos" crossContext="true"/> And I named this xml file as uploads.xml and saved under "#Tomcat\conf\Catalina\localhost" here # = Directory where Tomcat has been installed. And when I start Tomcat(5) from cammand line (batch file) i.e. startup.bat The images can be accessed normally like "http://localhost:8080/uploads/user1.png" It works. Actually I am using IntelliJ Idea 8 for devevelopment. When I start Tomcat from IntelliJ Idea, I am not able to access the context i.e. the images. "http://localhost:8080/uploads/user1.png" It shows "HTTP 400 Bad Request" The context path for my project is "http://localhost:8080/spark/" Any help or suggestion is needed at the earliest time. Looking forward to as many appreciative responses as possible. Thanx Pink

• Documentation for installing and running hadoop 2.2 on Windows

  - by user2325154

  With the latest release of Hadoop 2.2 I see that the release notes mentions that this version has significant improvements for running Hadoop on Windows. I downloaded Hadoop 2.2 yesterday and I saw lot of .cmd file alon with .sh files which ensures that this version has scripts and batch files for running Hadoop on Windows environment. However while looking at the Apache Hadoop documentation I couldn't find any step-by-step instructions on how to install and run this newer version on Windows. Besides this it looks like that the newer version has YARN architecture embedded in it and the old configurations provided on some of the tutorials online may be outdated and not applicable anymore. Is there any good documentation for Hadoop 2.2 available online ? I want it specifically for running Hadoop under Windows.

• JSF 2 Content Controller (pull in content based on URI)

  - by gerges

  Hey All, I'm new to JSF and am trying to make a content controller. Basically whenever someone makes a request to www.myapp.com/external/** I'd like to forward to a controller that pulls external content into a page template and spits it out to the user. I was able to achive this pretty easily in Spring 3, but I'm a little confused on where to start with JSF. I feel like I'd need to create a custom servlet to handle /external/**? But what would the class of this servlet be? What would it consist of? Any help is appreciated!

• Good ACL implementation in Java

  - by yonconf

  Hi All. I'm implementing a web based document management system and I'd like to implement ACLs in my system. My formal requirements are hierarchal permissions (documents inherit permissions from their folders) user groups (users can dynamically create groups and associate users with groups). Such groups can have permissions on objects in the system. My code will query permission on objects in two cases: 1. Manipulating a single document 2. Listing all documents where a manipulation is possible The latter requirement seems the achilles heel for Spring Security ACLs (their method seems likely to incur multiple DB hits for each document I manage) Anyone know of another ACL implementation? Thanks!

• SQL compare entire rows

  - by zmaster

  In SQL server 2008 I have some huge tables (200-300+ cols). Every day we run a batch job generating a new table with timestamp appended to the name of the table. The the tables have no PK. I would like a generic way to compare 2 rows from two tables. Showing which cols having different values is sufficient, but showing the values would be perfect. Thanks a lot Thanks for the answers. I ended up writing my own C# tool to do the job - as Im not allowed to install 3rd party software in my company.

• What do I use for a J2ee website?

  - by johnny

  Not sure if I asked this correctly. I am trying to see what I need to create an website that uses MVC and that connects to legacy multiple databases, brining back those database info into one page. I wanted the site to be MVC but am not sure where to begin. Do I use Spring? What do I use for an server? Jboss and apache? Hibernate? I'm just kind of lost on how to proceed. It's not a straight forward a asp.net mvc or a php framwork. A major concern is the collection of data from multiple legacy databases and bringing that data back into one page. Thanks.
