• Internal and External Bug-Tracking Setup

  - by devdude

  Most of you certainly use some kind of bugtracker. Maybe internally only, once a customer files a bug via email or phone you add a new ticket by yourself. Sometimes weekly project meetings can be great source of new tickets coming preferably in flavors of excel sheets that the PM on the other side of the table loves to maintain and chase after you. The more advanced (and transparent) version: Allow the customer to file (and see the progress of) his bugs directly into you bugtracker. Systems like JIRA allow you to use profiles to have certain access rights, etc. But now the question: The bug raised by a user not necessary translates into 1 bug in a specific module/method/EJB/class. The version of the (your) web application he uses does not translate into the version of the class that is causing the error. How you maintain the internal part of the ticket with all the nasty techy details and the same time the make-the-user-feel-good ticket (need more info, accepted, in progress,..) ? Creating 2 tickets for internal and external ? Link them ? Any smart recipes to share ?

• Python sudoku programming

  I need your help on this. I have this program and I must finish it. It's missing 3 parts. Here is the program I'm working with: import copy def display(A): if A: for i in range(9): for j in range(9): if type(A[i][j]) == type([]): print A[i][j][0], else: print A[i][j], print print else: print A def has_conflict(A): for i in range(9): for j in range(9): for (x,y) in get_neighbors(i,j): if len(A[i][j])==1 and A[i][j]==A[x][y]: return True return False # HERE ARE THE PARTS THAT REQUIRE HELP!!!! def get_neighbors(x,y): return [] def update(A, i, j, value): return [] def solve(A): return [] # ENDS PARTS THAT REQUIRE HELP!!!!

• How to set "Run this program as an administrator" programatically.

  - by Patrick

  I'm having a problem with good ol' bdeadmin.exe in Vista. First, let's get the predictable responses out of the way: "You should not require your application to be elevated." This one does. C'est la vie. "You need to embed a manifest file." It is already compiled, it is many years old, the company that created it has no intention of doing it again, and it is installed from a Merge Module (MSM file). "BDE is obsolete, you should be using dbExpress" One and a half million lines of code. 'Nuff said. "Drop a manifest file next to the EXE." Tried that, did nothing. As a test, that same manifest file was able to make several other EXE files require elevation, just not the one I wanted. Something in there is preventing the external manifest from being read. "Create a shortcut and set SLDF_RUNAS_USER." Can't do that, it's a Control Panel applet. The only thing that worked was setting "Run this program as an administrator" under the Compatibility tab of its Properties window. I shouldn't have to tell users to do this. Bad for business. I need to have the installer do this. The MSM file uses a static path. Any ideas?

• Django Upload form to S3 img and form validation

  - by citadelgrad

  I'm fairly new to both Django and Python. This is my first time using forms and upload files with django. I can get the uploads and saves to the database to work fine but it fails to valid email or check if the users selected a file to upload.

• Resizing image algorithm in python

  - by hippocampus

  So, I'm learning my self python by this tutorial and I'm stuck with exercise number 13 which says: Write a function to uniformly shrink or enlarge an image. Your function should take an image along with a scaling factor. To shrink the image the scale factor should be between 0 and 1 to enlarge the image the scaling factor should be greater than 1. This is not meant as a question about PIL, but to ask which algorithm to use so I can code it myself. I've found some similar questions like this, but I dunno how to translate this into python. Any help would be appreciated. I've come to this: import image win = image.ImageWin() img = image.Image("cy.png") factor = 2 W = img.getWidth() H = img.getHeight() newW = int(W*factor) newH = int(H*factor) newImage = image.EmptyImage(newW, newH) for col in range(newW): for row in range(newH): p = img.getPixel(col,row) newImage.setPixel(col*factor,row*factor,p) newImage.draw(win) win.exitonclick() I should do this in a function, but this doesn't matter right now. Arguments for function would be (image, factor). You can try it on OP tutorial in ActiveCode. It makes a stretched image with empty columns :.

• Excel Range Format: Number is automatically formatted when Range::Value2 is set

  - by A9S6

  I have an Excel addin written in C# that imports a text file into Excel worksheet. Some of the fields in the file are text and some oare numbers. Problem Steps: Change the System's Regional Settings to Dutch (Belgium) Open Excel and import the file into Excel. Records contain values such as 78,1118 which gets converted to 781.118. Note that in Dutch(Belgium), COMMA is the decimal character and DOT is the thousand character. I do not require the number to be formatted automatically but just want to display whatver I get from the file (78,1118). If I set the cell's NumberFormat to "@" i.e. Text, then it displays an error (SmartTag) saying "Number stored as Text". I know I can change the settings by going to the "Options" box but I dont want to change any user options in Excel for this. I have tried setting the cell's Value2 with an "'" (apostrophe) but the same error is displayed. If I set the cell's format to something else after the value is set then the actual value changes and I loose the decimal. Is there a way in Excel to just display the value and NOT display the "Number Stored as Text" error in cell?

• MySQL Connector for .NET - Is it REALLY mature?

  - by effkay

  After spending a miserable month with MySQL/.NET/EntityFramework, my findings: Support for Entity Framework is VERY primitive, please use it for student-subjects type of database. Kindly do not consider it using for serious development as they ARE STILL unable to sort out VERY BASIC things like: it DOES NOT support unsigned stuff it DOES NOT support unsigned columns as FK; if you try, it gives you a beautiful exception; "The specified value is not an instance of a valid constant type\r\nParameter name: value" [http://bugs.mysql.com/bug.php?id=44801] blob cannot store more then few KB; cannot compare null object with a column with a LEGAL null value [http://bugs.mysql.com/bug.php?id=49936] they are unable to write VERY PRIMITIVE check to return date as null if value in column is 0000-00-00 00:00:00 if you use Visual Studio; sorry; mysql/sun guys hate Microsoft, they will NOT LET you import more then two or three tables (for Micky Mouse type of tables, they allow five; but thats it) - if you try, it will throw TIME OUT error on your face ... unless you are smart enough to change the connection time in connection string Anyone who would like to add in above list? WISH I would have seen a list like this before I selected MySQL :(

• Storing statistics of multple data types in SQL Server 2008

  - by Mike

  I am creating a statistics module in SQL Server 2008 that allows users to save data in any number of formats (date, int, decimal, percent, etc...). Currently I am using a single table to store these values as type varchar, with an extra field to denote the datatype that it should be. When I display the value, I use that datatype field to format it. I use sprocs to calculate the data for reporting; and the datatype field to convert to the appropriate datatype for the appropriate calculations. This approach works, but I don't like storing all kinds of data in a varchar field. The only alternative that I can see is to have separate tables for each datatype I want to store, and save the record information to the appropriate table based on datatype. To retreive, I run a case statement to join the appropriate table and get the data. This seems to solve. This however, seems like a lot of work for ... what gain? Wondering if I'm missing something here. Is there a better way to do this? Thanks in advance!

• How to connect to a queue manager with ssl enabled server connection channel when authentication is

  - by Dr. Xray

  I am trying to write a java application connecting to server connection channel with SSL enabled. So far, I have been successfully connected to the channel by setting authentication to 'optional'. However, when I set it to be 'required', the connection fails. Here is what I did: Create key db for queue manager and keystore for the java client user. Create key/self-signed certificates for the queue manager and the client user, with names prefixed ibmwebspheremq. Export, exchange and import certificates for the queue manager and the client. (I did answered 'yes' when being asked whether I trust the queue manager cert). The location and password to the truststore and keystore are set to point to the same keystore at the client side, where the orgininal created client user key and the imported queue manager key are. With other settings being the same, if I switch back to 'optional' authentication, the connection works. I think there is something I understand incorrectly about this ssl authenticaion but cannot figure out what. Could someone kindly help me?

• In need of help with setting up the open source library JFreeChart

  - by ssbellows

  I am having trouble with setting up the open source library JFreeChart for creating charts using Java. This is the process I have followed so far in trying to set it up: I downloaded the latest version from their download page http://sourceforge.net/projects/jfreechart/files/. I then unpacked the jfreechart-1.0.13.zip in the directory C:\JFreeChart\jfreechart-1.0.13\ on my system drive. In the unpacked directory there is a folder entitled "lib" which contains the packaged .jar files specified as necessary to use JFreeChart. I added the following directory to my classpath: C:\JFreeChart\jfreechart-1.0.13\lib\ I then created a simple program and added the line "import org.jfree.chart.*;" to see if it would compile with a package imported from JFreeChart. I navigated to the folder in which my sample program was contained and compiled with the following command: "javac -classpath C:\ Program.java" I was given the following error: "package org.jfree.chart does not exist" Could someone please give me some input as to what I have done incorrectly in this setup process? This is the first time I've tried using an open source library, so I don't have any prior experience to go on myself. Thank you very much in advance.

• Use Maven to trigger a wsgen & wsimport in a row, using wsdlLocation

  - by ben

  I have hard times using maven to generate my client. So Please refer to http://stackoverflow.com/questions/2131001/creating-a-web-service-client-directly-from-the-source for the first part of my question. To keep it simple and short, I want to go from here (a file in src/main/java) : package com.example.maven.jaxws.helloservice; import javax.jws.WebService; @WebService public class Hello { public String sayHello(String param) { ; return "Hello " + param; } } to there : /** * This class was generated by the JAX-WS RI. * JAX-WS RI 2.1.7-b01- * Generated source version: 2.1 * */ @WebServiceClient(name = "HelloService", targetNamespace = "http://helloservice.jaxws.maven.example.com/", wsdlLocation = "http://localhost:8080/test/") public class HelloService extends Service { private final static URL HELLOSERVICE_WSDL_LOCATION; private final static Logger logger = Logger.getLogger(com.example.wsimport.HelloService.class.getName()); ...etc using only 1 pom.xml file. Please note the wsdlLocation set on the end. The pom.xml file will probably use both maven-jaxws-plugin wsgen AND wsimport with some tricky configuration to achieve this.

• 'Must Override a Superclass Method' Errors after importing a project into Eclipse

  - by Tim H

  Anytime I have to re-import my projects into Eclipse (if I reinstalled Eclipse, or changed the location of the projects), almost all of my overridden methods are not formatted correctly, causing the error 'The method ?????????? must override a superclass method'. It may be noteworthy to mention this is with Android projects - for whatever reason, the method argument values are not always populated, so I have to manually populate them myself. For instance: list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() { public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { //These arguments have their correct names } }); will be initially populated like this: list.setOnCreateContextMenuListener(new OnCreateContextMenuListener() { public void onCreateContextMenu(ContextMenu arg1, View arg2, ContextMenuInfo arg3) { //This methods arguments were not automatically provided } }); The odd thing is, if I remove my code, and have Eclipse automatically recreate the method, it uses the same argument names I already had, so I don't really know where the problem is, other then it auto-formatting the method for me. This becomes quite a pain having to manually recreate ALL my overridden methods by hand. If anyone can explain why this happens or how to fix it .. I would be very happy. Maybe it is due to the way I am formatting the methods, which are inside an argument of another method?

• Setting System.Drawing.Color through .NET COM Interop

  - by Maxim

  I am trying to use Aspose.Words library through COM Interop. There is one critical problem: I cannot set color. It is supposed to work by assigning to DocumentBuilder.Font.Color, but when I try to do it I get OLE error 0x80131509. My problem is pretty much like this one: http://bit.ly/cuvWfc update: Code Sample: from win32com.client import Dispatch Doc = Dispatch("Aspose.Words.Document") Builder = Dispatch("Aspose.Words.DocumentBuilder") Builder.Document = Doc print Builder.Font.Size print Builder.Font.Color Result: 12.0 Traceback (most recent call last): File "aaa.py", line 6, in <module> print Builder.Font.Color File "D:\Python26\lib\site-packages\win32com\client\dynamic.py", line 501, in __getattr__ ret = self._oleobj_.Invoke(retEntry.dispid,0,invoke_type,1) pywintypes.com_error: (-2146233079, 'OLE error 0x80131509', None, None) Using something like Font.Color = 0xff0000 fails with same error message While this code works ok: using Aspose.Words; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Document doc = new Document(); DocumentBuilder builder = new DocumentBuilder(doc); builder.Font.Color = System.Drawing.Color.Blue; builder.Write("aaa"); doc.Save("c:\\1.doc"); } } } So it looks like COM Interop problem.

• Partial mapping in Entity Framework 4

  - by Dimi Toulakis

  Hi guys, I want to be able to do the following: I have a model and inside there I do have an entity. This entity has the following structure: public class Client { public int Id { get; set; } public string Name { get; set; } public string Description { get; set; } } What I want now, is to just get the client name based on the id. Therefore I wrote a stored procedure which is doing this. CREATE PROCEDURE [Client].[GetBasics] @Id INT AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; SELECT Name FROM Client.Client INNER JOIN Client.Validity ON ClientId = Client.Id WHERE Client.Id = @Id; END Now, going back to VS, I do update the model from the database with the stored procedure included. Next step is to map this stored procedure to the client entity as a function import. This also works fine. Trying now to load one client's name results into an error during runtime... "The data reader is incompatible with the specified 'CSTestModel.Client'. A member of the type, 'Id', does not have a corresponding column in the data reader with the same name." I am OK with the message. I know how to fix this (returning as resultset Id, Name, Description). My idea behind this question is the following: I just want to load parts of the entity, not the complete entity itself. Is there a solution to my problem (except creating complex types)? And if yes, can someone point me to the right direction? Many thanks, Dimi

• How to use 3rd party libraries in glassfish?

  - by Hank

  I need to connect to a MongoDB instance from my EJB3 application, running on glassfish 3.0.1. The Mongo project provides a set of drivers, and I'm able to use them in a standalone Java application. How would I use them in a JEE application? Or maybe better phrasing: how would I make a 3rd party library available to my application when it runs in an EJB container? At the moment, I'm getting a java.lang.NoClassDefFoundError when deploying a bean that tries to import from the library: [#|2010-03-24T11:42:15.164+0100|SEVERE|glassfishv3.0|global|_ThreadID=28;_ThreadName=Thread-1;|Class [ com/mongodb/DBObject ] not found.

Do I need to 'register' the library with the container? Reference it via Annotation? Extend the classpath of the container to include the library?

• E-commerce platform for custom application integration

  - by Zach Smith

  We are building an online subscription-based website and I'm looking for recommendations on which e-commerce platform to use for the checkout process. Requirements include: Only four products. The sign-up process of the site is heavily customized, and after checkout the user should automatically get logged into the subscriber area. Subscriptions will last one year and can be renewed manually. Support for coupons/discount codes at a later point. Since the entire application is custom, we've weighed building a custom checkout but are strongly leaning towards using existing software to avoid having to build lots of admin reporting as well as a coupon engine down the road. The two questions we're pondering are: Is it better to a) build our application custom and use whatever e-commerce software we select just for the payment piece, or b) use the e-commerce software as the basis and build our application around it/as a module/etc? Which e-commerce platform should we use? I've looked into a variety of off the shelf e-commerce software, but it's not clear to me which would be easiest to integrate with. I've researched on the Web and looked at many of the threads on SO to compiled a list of potential candidates: www.magentocommerce.com/ (seems difficult to integrate with) www.prestashop.com/ www.nopcommerce.com/ www.opencart.com/ www.cubecart.com/ www.spreecommerce.com/ www.interspire.com/ www.tradingeye.com/ We're most concerned with the level of effort required with ramping up on the software and then doing the integration with our custom functionality. We're most proficient with PHP, ASP.NET and some ROR and are only considering those technologies. We prefer open source, but would be open to commercial if there's a significant upside. Any experiences with similar projects and advice is greatly appreciated.

• Create Keyword Object Perl Microsoft::AdCenter

  - by toobsco42

  So I looked at the perldoc for the Microsoft::AdCenter module and it shows this as an example of how to create a keyword object: ~$ perldoc Microsoft::AdCenter #Create a Keyword object my $keyword = Microsoft::AdCenter::V7::CampaignManagementService::Keyword->new ->Text("some text") ->BroadMatchBid(Microsoft::AdCenter::V7::CampaignManagementService::Bid->new->Amount(0.1)) ->ExactMatchBid(Microsoft::AdCenter::V7::CampaignManagementService::Bid->new->Amount(0.1)); However, doesn't this violate the new policy of using only one match type per keyword? Campaign Management changes: "Previously, you would create a single Keyword object and specify a bid value for each match that you wanted to bid on (for example, exact match or phrase match). If you did not specify a bid value at the keyword-level, adCenter used the default bid value specified at the ad group level. Now, you must create a Keyword object for each match type that you want to bid on. For example, to bid on the keyword car by using exact match and phrase match, create a Keyword object and set the Text element to car and the ExactMatchBid element to a bid amount. Then, create a second Keyword object and set the Text element to car and PhraseMatchBid to a bid amount. When you add the keywords, you’ll get a unique keyword ID for each keyword and match-type combination."

• How to express inter project dependencies in Eclipse PDE

  - by Roland Tepp

  I am looking for the best practice of handling inter project dependencies between mixed project types where some of the projects are eclipse plug-in/OSGI bundle projects (an RCP application) and others are just plain old java projects (web services modules). Few of the eclipse plug-ins have dependencies on Java projects. My problem is that at least as far as I've looked, there is no way of cleanly expressing such a dependency in Eclipse PDE environment. I can have plug-in projects depend on other plug-in projects (via Import-Package or Require-Bundle manifest headers), but not of the plain java projects. I seem to be able to have project declare a dependency on a jar from another project in a workspace, but these jar files do not get picked up by neither export nor launch configuration (although, java code editing sees the libraries just fine). The "Java projects" are used for building services to be deployed on an J2EE container (JBoss 4.2.2 for the moment) and produce in some cases multiple jar's - one for deploying to the JBoss ear and another for use by client code (an RCP application). The way we've "solved" this problem for now is that we have 2 more external tools launcher configurations - one for building all the jar's and another for copying these jar's to the plug-in projects. This works (sort of), but the "whole build" and "copy jars" targets incur quite a large build step, bypassing the whole eclipse incremental build feature and by copying the jars instead of just referencing the projects I am decoupling the dependency information and requesting quite a massive workspace refresh that eats up the development time like it was candy. What I would like to have is a much more "natural" workspace setup that would manage dependencies between projects and request incremental rebuilds only as they are needed, be able to use client code from service libraries in an RCP application plug-ins and be able to launch the RCP application with all the necessary classes where they are needed. So can I have my cake and eat it too ;) NOTE To be clear, this is not so much about dependency management and module management at the moment as it is about Eclipse PDE configuration. I am well aware of products like [Maven], [Ivy] and [Buckminster] and they solve a quite different problem (once I've solved the workspace configuration issue, these products can actually come in handy for materializing the workspace and building the product)

• An SVN error (200 OK) when checking out from my online repo

  - by J. LaRosee

  I'm trying to setup my first repo on my host and am getting this error when I use Tortoise to checkout the project: Error: OPTIONS of 'http://mywebsite.com/svn/myproject': 200 OK (http://mywebsite.com) Here is what I did: 1) ssh into my host and head to /home/myaccnt and 'svnadmin create svn' 2) create my project repo: 'svn mkdir svn/myproject' 3) add files to the repo: cd /home/myaccnt/.../myproject (which has /tags, /branch, /trunk); 'svn import file:///home/myaccnt/svn/myproject' (the big ole list of files being added is seen at this point.) At this point I think that I've setup my repo and imported my project into the repo. So, I'm ready to checkout using TortoiseSVN on my Windows box. So: 4) In the folder I'd like to checkout to, I rightclick and 'SVN Checkout' and then make sure my URL is: http://mywebsite.com/svn/myproject Result?

I'm likely missing something fundemental w/ the structure of my repo or htaccess... or something. Many thanks in advance. -JL

• Oracle rownum in db2 - Java data archiving

  - by HonorGod

  I have a data archiving process in java that moves data between db2 and sybase. FYI - This is not done through any import/export process because there are several conditions on each table that are available on run-time and so this process is developed in java. Right now I have single DatabaseReader and DatabaseWriter defined for each source and destination combination so that data is moved in multiple threads. I guess I wanted to expand this further where I can have Multiple DatabaseReaders and Multiple DatabaseWriters defined for each source and destination combination. So, for example if the source data is about 100 rows and I defined 10 readers and 10 writer, each reader will read 10 rows and give them to the writer. I hope process will give me extreme performance depending on the resources available on the server [CPU, Memory etc]. But I guess the problem is these source tables do not have primary keys and it is extremely difficult to grab rows in multiple sets. Oracle provides rownum concept and i guess the life is much simpler there....but how about db2? How can I achieve this behavior with db2? Is there a way to say fetch first 10 records and then fetch next 10 records and so on? Any suggestions / ideas ? Db2 Version - DB2 v8.1.0.144 Fix Pack Num - 16 Linux

• Replacing a Namespace with XSLT

  - by er4z0r

  Hi I want to work around a 'bug' in certain RSS-feeds, which use an incorrect namespace for the mediaRSS module. I tried to do it by manipulating the DOM programmatically, but using XSLT seems more flexible to me. Example: <media:thumbnail xmlns:media="http://search.yahoo.com/mrss" url="http://www.suedkurier.de/storage/pic/dpa/infoline/brennpunkte/4311018_0_merkelxI_24280028_original.large-4-3-800-199-0-3131-2202.jpg" /> <media:thumbnail url="http://www.suedkurier.de/storage/pic/dpa/infoline/brennpunkte/4311018_0_merkelxI_24280028_original.large-4-3-800-199-0-3131-2202.jpg" /> Where the namespace must be http://search.yahoo.com/mrss/ (mind the slash). This is my stylesheet: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="//*[namespace-uri()='http://search.yahoo.com/mrss']"> <xsl:element name="{local-name()}" namespace="http://search.yahoo.com/mrss/" > <xsl:apply-templates select="@*|*|text()" /> </xsl:element> </xsl:template> </xsl:stylesheet> Unfortunately the result of the transformation is an invalid XML and my RSS-Parser (ROME Library) does not parse the feed anymore: java.lang.IllegalStateException: Root element not set at org.jdom.Document.getRootElement(Document.java:218) at com.sun.syndication.io.impl.RSS090Parser.isMyType(RSS090Parser.java:58) at com.sun.syndication.io.impl.FeedParsers.getParserFor(FeedParsers.java:72) at com.sun.syndication.io.WireFeedInput.build(WireFeedInput.java:273) at com.sun.syndication.io.WireFeedInput.build(WireFeedInput.java:251) ... 8 more What is wrong with my stylesheet?

Once we bring the application up and hit it, its opening 140 connections and not releasing it. Our DAO looks like this: import org.springframework.orm.hibernate3.support.HibernateDaoSupport; ... public class ActionDAO extends HibernateDaoSupport implements IActionDAO { public Action findById(ActionPK actionPK) { return (Action) getHibernateTemplate().get(Action.class, actionPK); } public void add(Action action) { getHibernateTemplate().save(action); } }
