  • Define DataSource bean on code

    - by Ruben Trancoso
    I would like to make a "First Access Database Setup Process" in my spring application and the only thing I can imagine as a solution would be to initialize the DataSource bean programatically. My current bean is defined as: <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/catalog" /> <property name="username" value="condominium" /> <property name="password" value="password" /> <property name="validationQuery" value="SELECT 1" /> <property name="testOnBorrow" value="true" /> <property name="defaultAutoCommit" value="false" /> <property name="maxWait" value="5000" /> </bean> but the ideal thing was to load it by myself in whenever I need it and with the parameter I define. The scenario is that the user (administrator) comes to the application at the first time and I ask him the server, port and catalog to connect. I store it in a embeeded db and next time application start, a bean can check if the parameter are set on the embedded db and load it again. Is it possible?

  • Ant: project dependencies in a flat project layout with ivy

    - by MH
    Hello, I have two (Eclipse-) projects. Project A depends on project B, but the projects aren't nested i.e. project A is not a subproject of project B. Apache Ivy is responsible for the dependency management. When I run the compile task in Project A, is there any way to trigger the compile task (in project B) automatically (for example if the jar file of project B doesn't exist)? Thanks a million in advance.

  • What Java CMIS client library should I use?

    - by Nicolas Raoul
    I am starting a new project and must decide which CMIS client library we will use. Our Java project just needs to connect an a CMIS server (actually Alfresco but it should not matter), in order to perform some read/write/search operations. I am looking for a client library that: is already usable is not going to be abandoned soon has an active community of users is open source Which one would you recommend and why? Here are a few possibilities: Apache Chemistry's OpenCMIS chemistry-atompub-client chemistry-abdera Abdera Parse the XML manually

  • PNGs alpha transparancy in AS3 - Unknown file-type

    - by WiseDonkey
    Hello there! After whittling down of the options we've encountered a problem with PNG's and ActionScript 3 (AS3). When loading a PNG 8 or PNG 32 with alpha transparancy we're getting the following error reported in Flash:- "Error #2124: Loaded file is an unknown type" Now, we're dealing with some legacy images, and it appears as though this problem isn't universal - some images believed to be 32bit alpha PNG are loading. BUT, some conclusions:- converting one image that was 32 bit alpha (NOT WORKING IN AS3) to PNG 8 index transparency DID work. And converting that same image to PNG 8 alpha DID NOT work. These all worked in AS2 There is no difference between the headers Headers of a Failing Image [0] => HTTP/1.1 200 OK [1] => Date: Tue, 06 Apr 2010 14:17:28 GMT [2] => Server: Apache/2.2.3 (Red Hat) [3] => Last-Modified: Tue, 06 Apr 2010 13:44:05 GMT [4] => ETag: "3700054-11d6-a3983340" [5] => Accept-Ranges: bytes [6] => Content-Length: 4566 [7] => Connection: close [8] => Content-Type: image/png Headers of a Working Image [0] => HTTP/1.1 200 OK [1] => Date: Tue, 06 Apr 2010 14:19:02 GMT [2] => Server: Apache/2.2.3 (Red Hat) [3] => Last-Modified: Fri, 30 Oct 2009 18:38:08 GMT [4] => ETag: "ba8057-65f2-5445c400" [5] => Accept-Ranges: bytes [6] => Content-Length: 26098 [7] => Connection: close [8] => Content-Type: image/png Any thoughts of a direction of further investigation or thoughts on a bewildering problem with little to no documentation; very warmly welcomed. EDIT Now it would appear as though something in the PHP conversion of the images is shafting; I use the following PHP to add alpha layers:- imagealphablending($image_p, false); ImageSaveAlpha($image_p, true); ImageFill($image_p, 0, 0, IMG_COLOR_TRANSPARENT);

  • Easy to follow LaTeX tutorial on layout?

    - by lexu
    I want to layout a page using LaTeX and distribute text snippets/blocks in predefined locations. Something like this +--------------------------------------------------------+ | +-------------+ | | |bla bla bla| | | |bla bl ab lab| +-------------+ | | |bla bla bla| |bla bla bla| | | |bla bl ab lab| |bla bl ab lab| | | +-------------+ |bla bla bla| | | |bla bl ab lab| | | +-------------+ +----+ | | |more| | | Ich und Du |text| | | Müllers Kuh +----+ | | | +--------------------------------------------------------+ My guess is that I should go about this using a minipage or using boxes like \begin{minipage}[b][2cm]{8cm} \mbox{more} \newline \mbox{text} \newline \end{minipage} Is there a tutorial or a 'how to' page that you know, that shows me how to do this - not a list all LaTeX idioms, I have some books for that. But my books are more focused on command lists, scientific publishing and math ..

  • StringTokenizer split at "<br/>"

    - by AnAmuser
    Maybe I am stupid but I don't understand why the behaviour of StringTokenizer here: import static org.apache.commons.lang.StringEscapeUtils.escapeHtml; String object = (String) value; String escaped = escapeHtml(object); StringTokenizer tokenizer = new StringTokenizer(escaped, escapeHtml("<br/>")); If fx. value is Hej<br/>$user.get(0).name Har vundet<br/><table border='1'><tr><th>Name</th><th>Played</th><th>Brewed</th></tr>#foreach( $u in $user )<tr><td>$u.name</td> <td>$u.played</td> <td>$u.brewed</td></tr>#end</table><br/> Then the result is Hej $use . e (0).name Ha vunde a e o de ='1' h Name h h P ayed h h B ewed h #fo each( $u in $use ) d $u.name d d $u.p ayed d d $u. ewed d #end a e It makes no sense to me. How can I make it behave as I expect to.

  • Mathematica - Import CSV and process columns?

    - by Casey
    I have a CSV file that is formatted like: 0.0023709,8.5752e-007,4.847e-008 and I would like to import it into Mathematica and then have each column separated into a list so I can do some math on the selected column. I know I can import the data with: Import["data.csv"] then I can separate the columns with this: StringSplit[data[[1, 1]], ","] which gives: {"0.0023709", "8.5752e-007", "4.847e-008"} The problem now is that I don't know how to get the data into individual lists and also Mathematica does not accept scientific notation in the form 8.5e-007. Any help in how to break the data into columns and format the scientific notation would be great. Thanks in advance.

    - by Chmouel Boudjnah
    Hi, I want to make a apps that check what's the nearest place from where the user is. I can easily get the location of the user and I have a list of places with latitude and longitude. What would be the best way to know the nearest place of the list against the current position. I could not find anything in the google APIs. I am worried I need to resort to my calculate and have to do math to calculate it. What do you guys think ? Cheers and thanks for reading or replying.

  • Statistics: combinations in Python

    - by Morlock
    I need to compute combinatorials (nCr) in Python but cannot find the function to do that in 'math', 'numyp' or 'stat' libraries. Something like a function of the type: comb = calculate_combinations(n, r) I need the number of possible combinations, not the actual combinations, so itertools.combinations does not interest me. Finally, I want to avoid using factorials, as the numbers I'll be calculating the combinations for can get to big and the factorials are going to be monstruous. This seems like a REALLY easy to answer question, however I am being drowned in questions about generating all the actual combinations, which is not what I want. :) Many thanks

    I am using Apache FOP 0.95, and all I want to do is add 1 to the current page number. So, on page 12, I want to show 12 / 13. Then nothing on page 13, of course. Any ideas how I could do this, perhaps by manipulating <fo:page-number /> ? Thanks y'all!

  • Python Mersenne Twister implementation

    - by B Rivera
    I have Python 3.1.2 and I'm using Windows XP. Where can I see Python's implementation of the Mersenne Twister? In the Python docs it is stated that the Mersenne Twister was written in C and the Python History and License ( http://docs.python.org/py3k/license.html?highlight=mersenne%20twister ) states that "The _random module includes code based on a download from http://www.math.keio.ac.jp/matumoto/MT2002/emt19937ar.html." random.py imports _random which apparently has the Mersenne Twister implementation in it. I can't seem to locate _random. Any thoughts?

  • XSL-FO: is XSL-FO dead technology and only used by niche companies?

    - by MMAmail.com
    I wanted to convert some xml to a magazine like pdf document. A lot like what Latext allows you to do however i was not able to find any new books or online tutorials on the subject. Is it worth investing in using this technology or not? Also, I looked at the Apache XSL-FO project and their last release was in august 2008. p.s. commercial packages are not an option :(

  • multiple Thrift services on one transport

    - by kert
    Just seeking confirmation here : apache Thrift protocol does not seem to support running multiple services on one transport endpoint ? ( a socket, file, whatever ) I cant seem to figure out how to do something like this in Thrift: service otherService { void dosomething() } service rootService { otherService getOtherService() } There does not seem to be any concept of passing in and out service handles, ultimately limited by the protocol. Looks like you can not run two services on one transport pipe. Correct ?

  • Explaining training method for AdaBoost algorithm

    - by konzti8
    Hi, I'm trying to understand the Haar feature method used for the training step in the AdaBoost algorithm. I don't understand the math that well so I'd appreciate more of a conceptual answer (as much as possible, anyway). Basically, what does it do? How do you choose positive and negative sets for what you want to select? Can it be generalized? What I mean by that is, can you choose it to find any kind of feature that you want no matter what the background is? So, for example, if I want to find some kind of circular blob - can I do that? I've also read that it is used on small patches for the images around the possible feature - does that mean you have to manually select that image patch or can it be automated to process the entire image? Is there matlab code for the training step? Thanks for any help...

  • Scapy PcapReader and packets time

    - by auino
    I'm reading a PCAP file using Scapy using a script such as the (semplified) following one: #! /usr/bin/env python from scapy.all import * # ... myreader = PcapReader(myinputfile) for p in myreader: pkt = p.payload print pkt.time In this case the packets time is not relative to PCAP capture time, but starts from the instant I've launched my script. I'd like to start from 0.0 or to be relative to the PCAP capture. How can I fix it (possibly without "manually" retrieving the first packet time and repeatedly using math to fix the problem)?

  • How to calculate order (big O) for more complex algorithms (ie quicksort)

    - by bangoker
    I know there are quite a bunch of questions about big O notation, I have already checked Plain english explanation of Big O , Big O, how do you calculate/approximate it?, and Big O Notation Homework--Code Fragment Algorithm Analysis?, to name a few. I know by "intuition" how to calculate it for n, n^2, n! and so, however I am completely lost on how to calculate it for algorithms that are log n , n log n, n log log n and so. What I mean is, I know that Quick Sort is n log n (on average).. but, why? Same thing for merge/comb, etc. Could anybody explain me in a not to math-y way how do you calculate this? The main reason is that Im about to have a big interview and I'm pretty sure they'll ask for this kind of stuff. I have researched for a few days now, and everybody seem to have either an explanation of why bubble sort is n^2 or the (for me) unreadable explanation a la wikipedia Thanks!

  • Gradient a Parallelogram

    - by nuclearpenguin
    I'm working in JavaScript drawing on a canvas, and have four coordinates to draw a parallelogram, called A, B, C, and D starting from the top-left, top-right, bottom-left, and bottom right, respectively. An example of some coordinates might be: A: (3, 3) B: (4, 3) C: (1, 0) D: (2, 0) I can draw the parallelogram just fine, but I would like to fill it in with a gradient. I want the gradient to fill in from left to right, but matching the angle of the shape. The library I use (CAKE) requires a start and stop coordinate for the gradient. My stop and start would be somewhere half way between A and C, and end somewhere half way between B and D. Of course, it is not simply EXACTLY half way because the angles at A, B, C, and D are not right angles. So given this information (the coordinates), how to I find the point on the line A - C to start, and the point on the line B - D to stop? Remember, I'm doing this in JavaScript, so I have some good Math tools at my disposal for calculation.
