  • getResourceAsStream not loading resource in webapp

    - by mangst
    I have a web application that uses a library which resides in TOMCAT_HOME/common/lib. This library looks for a properties file at the root of the classpath (in a class called ApplicationConfig): ApplicationConfig.class.getResourceAsStream("/hv-application.properties"); My Tomcat web application contains this properties file. It is in WEB-INF/classes, which is the root of the classpath right? However, at runtime, when it tries to load the properties file, it throws an exception because it can't find it (getResourceAsStream returns null). Everything works fine if my application is a simple, standalone Java application. Does Tomcat cause the getResourceAsStream method to act differently? I know there's a lot of similar questions out there, but none of them have helped unfortunately. Thanks.

  • are there any tree libraries/widgets for (n)curses

    - by phatmanace
    Hi - I wondered if there were any tree libraries available for (n)curses. I'm trying to write a component that shows a tree of folders & was curious if there was a prebuilt curses component that could do this. I've checked 'core' curses as well as libraries like CDK - and I can't seem to find anything. If none exists, I'm not averse to building my own - but I can't seem to locate any decent tutorials on doing this, so any help in this regard would also be much appreciated. Thanks, Ace

  • Visual Studio XSD Tool: Generate Collections Rather Than Arrays

    - by senfo
    I generated some C# classes from an XSD using the Visual Studio XSD utility and it generated arrays for storing a collection of elements, rather than one of the built-in generic Collection<T> (or related) classes. None of the command line parameters mentioned in xsd /? mention anything about generating collections rather than arrays, but I know that this can be done with web service proxy classes that Visual Studio generates, so I figured it must be possible. Does anybody know how to have the XSD utility generate collection classes rather than arrays?

  • LINQ to SQL -- Can't modify return type of stored procedure.

    - by Kyle Ryan
    When I drag a particular stored procedure into the VS 2008 dbml designer, it shows up with Return Type set to "none", and it's read only so I can't change it. The designer code shows it as returning an int, and if I change that manually, it just gets undone on the next build. But with another (nearly identical) stored procedure, I can change the return type just fine (from "Auto Generated Type" to what I want.) I've run into this problem on two separate machines. Any idea what's going on? Here's the stored procedure that works: USE [studio] GO /****** Object: StoredProcedure [dbo].[GetCourseAnnouncements] Script Date: 05/29/2009 09:44:51 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER OFF GO CREATE PROCEDURE [dbo].[GetCourseAnnouncements] @course int AS SELECT * FROM Announcements WHERE Announcements.course = @course RETURN And this one doesn't: USE [studio] GO /****** Object: StoredProcedure [dbo].[GetCourseAssignments] Script Date: 05/29/2009 09:45:32 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER OFF GO CREATE PROCEDURE [dbo].[GetCourseAssignments] @course int AS SELECT * FROM Assignments WHERE Assignments.course = @course ORDER BY date_due ASC RETURN

  • Need help with a conditional SELECT statement

    - by Ethan
    I've got a stored procedure with a select statement, like this: `SELECT author_ID, author_name, author_bio FROM Authors WHERE author_ID in (SELECT author_ID from Books) ` This limits results to authors who have book records. This is the Books table: Books book_ID INT author_ID INT book_title NVARCHAR featured_book BIT What I want to do is conditionally select the ID of the featured book by each author as part of the select statement above, and if none of the books for a given author are featured, select the ID of the first (top 1) book by the author from the books table. How do I approach this?

  • jQuery + Validation plugin: add/remove class to/from element's parent

    - by FreekOne
    Hi guys, I'm working with the jQuery Validation plugin and I wrote the following code which adds a class to the element's parent if not valid (as well as inserting the actual error message at a particular location within the parent): errorPlacement: function(error, element) { element.parent().addClass('error'); error.insertBefore(element.parent().children("br")); } This works, however, if a field's content is corrected and becomes valid, the class obviously doesn't get removed from its parent (actually, neither does the error element, instead it just gets a display: none; CSS property). How can I check if an element becomes valid and remove its parent class if so ? Any help would be much appreciated, thank you !

  • Setting Grouping in UITableView under UINavigationController

    - by climbon
    In my UINavigationController app, my first view is a UITableView. I can't seem to find a way to set the property of this UITableView to 'grouped'. Since UITableView is dynamically generated I don't have the luxury of Interface Builder. Searched forums here and googled other places and closest I saw was to override either initWithStyle or initWithCoder as follows. (id)initWithStyle:(UITableViewStyle)style { if (self = [super initWithStyle:UITableViewStyleGrouped]) { } return self; } However this above function never gets called. when I overrided initWithCoder I could see it worked and I was able to change UITableView contents to grouped. But then title automatically became 'Root View Controller' and none of the cells were active anymore although they got grouped fine. That is while they looked active but if you click on them, those cells won't do anything. But I have seen apps which have their very first view being UITableView is grouped. So there must be a way to do it but I don't know how.

  • Changing expiry on ASP.NET's Session State cookie

    - by Charlie Somerville
    I'm using ASP.NET Session State to keep track of logged in users on my site. However, one problem I'm running into is that by default ASP.NET session cookies are set to expire when the browser closes. I've tried setting my own ASP.NET_SessionId cookie and modifying the cookie's expiry using something similar to the following code: Response.Cookies["ASP.NET_SessionId"].Expires = DateTime.Now.AddMonths(1); None of these approaches work, they all set a second cookie with the same name. Is there a way of changing the session cookie's expiry?

  • Weird problem, with ghostscript and pdf files.

    - by kofucii
    Hello, am using ghostscript to create pdf file from postscript file. My PS file, doesn't have orientation instructions, so when I want to create landscape pdf file, I'm using ghostscript to rotate the page. The problem is, that ghostscript rotates only the first page, and when my pdf file is more than 1 page, the others, are not rotated correctly. Here is the command I'm using: cat $psinput | gs -sPAPERSIZE=a4 -sDEVICE=pdfwrite -sOuputFile="/tmp/pdf" \ -dAutoRotatePages="/None" -c "<< /Orientation 3 >> setpagedevice" \ 90 rotate 0 -595 translate -dNOPAUSE -dEPSCrop -f - -c -quit Does anybody have an idea how to correct this?

  • Tkinter Gui to read in csv file and generate buttons based on the entries in the first row

    - by Thomas Jensen
    I need to write a gui in Tkinter that can choose a csv file, read it in and generate a sequence of buttons based on the names in the first row of the csv file (later the data in the csv file should be used to run a number of simulations). So far I have managed to write a Tkinter gui that will read the csv file, but I am stomped as to how I should proceed: from Tkinter import * import tkFileDialog import csv class Application(Frame): def __init__(self, master = None): Frame.__init__(self,master) self.grid() self.createWidgets() def createWidgets(self): top = self.winfo_toplevel() self.menuBar = Menu(top) top["menu"] = self.menuBar self.subMenu = Menu(self.menuBar) self.menuBar.add_cascade(label = "File", menu = self.subMenu) self.subMenu.add_command( label = "Read Data",command = self.readCSV) def readCSV(self): self.filename = tkFileDialog.askopenfilename() f = open(self.filename,"rb") read = csv.reader(f, delimiter = ",") app = Application() app.master.title("test") app.mainloop() Any help is greatly appreciated!

  • how to pass arguments into function within a function in r

    - by jon
    I am writing function that involve other function from base R with alot of arguments. For example (real function is much longer): myfunction <- function (dataframe, Colv = NA) { matrix <- as.matrix (dataframe) out <- heatmap(matrix, Colv = Colv) return(out) } data(mtcars) myfunction (mtcars, Colv = NA) The heatmap has many arguments that can be passed to: heatmap(x, Rowv=NULL, Colv=if(symm)"Rowv" else NULL, distfun = dist, hclustfun = hclust, reorderfun = function(d,w) reorder(d,w), add.expr, symm = FALSE, revC = identical(Colv, "Rowv"), scale=c("row", "column", "none"), na.rm = TRUE, margins = c(5, 5), ColSideColors, RowSideColors, cexRow = 0.2 + 1/log10(nr), cexCol = 0.2 + 1/log10(nc), labRow = NULL, labCol = NULL, main = NULL, xlab = NULL, ylab = NULL, keep.dendro = FALSE, verbose = getOption("verbose"), ...) I want to use these arguments without listing them inside myfun. myfunction (mtcars, Colv = NA, col = topo.colors(16)) Error in myfunction(mtcars, Colv = NA, col = topo.colors(16)) : unused argument(s) (col = topo.colors(16)) I tried the following but do not work: myfunction <- function (dataframe, Colv = NA) { matrix <- as.matrix (dataframe) out <- heatmap(matrix, Colv = Colv, ....) return(out) } data(mtcars) myfunction (mtcars, Colv = NA, col = topo.colors(16))

  • Visual Studios Team System 2008 Code Coverage Window Closes

    - by ThoughtCrhyme
    Trying to run the code coverage tool in Visual Studios for a set of unit tests. Adam from Think First, Code Later has had the same problem: I wanted to get the code coverage metrics for the project. Naturally, I fire up the solution in Visual Studio 2008, go to the Test menu, click Edit Test Run Configurations, and click Local Test Run. I then click Code Coverage to turn on code coverage for a given assembly and POOF the Local Test Run Configraution window just disappears. He recommends installing this hotfix to fix the problem, however a) when I run that hotfix I get the message “None of the products that are addressed by this software update are installed on this computer. Click Cancel to exit setup.” and b) there is no Silverlight in our solution. Any other ideas for a fix?

  • Service Application too visible

    - by Tom
    Working on a service application in Delphi 5 that is intended to run on Windows XP - 7. Most of the application is coming together nicely, but I'm running into one issue. Part of this service application is a form that displays data occasionally (similar to the slider box Avast uses to let you know its updated). When the service shows the form, the form displays on the taskbar, but we don't want it to. Does anyone have any suggestions as to how to hide the form's button on the taksbar? None of the standard methods I've found for regular applications have worked so far. Thanks.

  • JavaScript Array Problem

I am trying to create a multi-dimensional array. var photos = new Array; var a = 0; $("#photos img").each(function(i) { photos[a]["url"] = this.src; photos[a]["caption"] = this.alt; photos[a]["background"] = this.css('background-color'); a++; }); Error message: photos[a] is undefined. How do I do this. Thanks.

  • How to make Universal Feed Parser only parse feeds?

    - by piquadrat
    I'm trying to get content from external feeds on my Django web site with Universal Feed Parser. I want to have some user error handling, e.g. if the user supplies a URL that is not a feed. When I tried how feedparser responds to faulty input, I was surprised to see that feedparser does not throw any Exceptions at all. E.g. on HTML content, it tries to parse some information from the HTML code, and on non-existing domains, it returns a mostly empty dictionary: {'bozo': 1, 'bozo_exception': URLError(gaierror(-2, 'Name or service not known'),), 'encoding': 'utf-8', 'entries': [], 'feed': {}, 'version': None} Other faulty input manifest themselves in the status_code or the namespaces values in the returned dictionary. So, what's the best approach to have sane error checking without resorting to an endless cascade of if .. elif .. elif ...?

  • .NET Thank you/confirmation page best practise

    - by sooty
    Hi, whats the best practise for implementing a confirmation page in .Net? I've used response.redirect("Thankyou.aspx") a lot in the past I've also used something like this for hiding form controls and outputting a message: outResult.Attributes.Remove("style") outResult.Attributes.Add("style", "display:block;") outEntry.Attributes.Remove("style") outEntry.Attributes.Add("style", "display:none;") For the above you have to consider post backs that may occur if the user click refresh though. Does anybody have a better option? thanks!
