  • How to use SLF4J Log4jLoggerAdapter

    - by David Wong
    I'm deploying an enterprise application on Weblogic 8.1 which has log4j 1.2.8 on it's classpath. I'm getting the following error with SLF4J 1.6.1: SLF4J versions 1.4.0 and later requires log4j 1.2.12 or later http://www.slf4j.org/codes.html#log4j_version Above link recommends using Log4jLoggerAdapter. I've changed Logger logger = LoggerFactory.getLogger(HelloWorld.class); logger.info("Hello World"); to Log4jLoggerAdapter logger = (Log4jLoggerAdapter) LoggerFactory.getLogger(HelloWorld.class); logger.info("Hello World"); However, I'm still encountering the error. Any advice on how to correctly implement this? Thanks

  • Loop over DOMDocument

    - by Zoredache
    I am following the suggestion from this question Robust, Mature HTML Parser for PHP, about parsing html that may be malformed with DOMDocument. Is there any easy way to loop over the parsed document? So I would like to loop over html like this. $html='<ul> <li>value1</li> <li>value1</li> <li>value3</li> </ul> <p>hello world</p>'; $doc = new DOMDocument(); $doc->loadHTML($html); ??? foreach (??? as $node) { print $node->nodeName.':'.$node->nodeValue; } And get results somewhat like this. ul: li:value1 li:value2 li:value3 p:hello world

  • weird behavior with acts_as_taggable_on

    - by macek
    For some reason, tags aren't showing up on a taggable object when an tagger is specified. testing the post class Post < ActiveRecord::Base acts_as_taggable_on :tags belongs_to :user end >> p = Post.first => #<Post id: 1, ...> >> p.is_taggable? => true >> p.tag_list = "foo, bar" => "foo, bar" >> p.save => true >> p.tags => [#<Tag id: 1, name: "foo">, #<Tag id: 2, name: "bar">] testing the user class User < ActiveRecord::Base acts_as_tagger has_many :posts end >> u = User.first => #<User id: 1, ...> >> u.is_tagger? => true >> u.tag(p, :with => "hello, world", :on => :tags) => true >> u.owned_tags => [#<Tag id: 3, name: "hello">, #<Tag id: 4, name: "world">] refresh the post >> p = Post.first => #<Post id: 1 ...> >> p.tags => [#<Tag id: 2, name: "bar">, #<Tag id: 1, name: "foo">] Where's the hello and world tags? Miraculously, if I modify the database directly to set tagger_id and tagger_type to NULL, the two missing tags will show up. I suspect there's something wrong with my User model? What gives?

  • how to work with strings and integers as bit strings in python?

    - by Manuel
    Hello! I'm developing a Genetic Algorithm in python were chromosomes are composed of strings and integers. To apply the genetic operations, I want to convert these groups of integers and strings into bit strings. For example, if one chromosome is: ["Hello", 4, "anotherString"] I'd like it to become something like: 0100100100101001010011110011 (this is not actual translation). So... How can I do this? Chromosomes will contain the same amount of strings and integers, but this numbers can vary from one algorithm run to another. To be clear, what I want to obtain is the bit representation of each element in the chromosome concatenated. If you think this would not be the best way to apply genetic operators (such as mutation and simple crossover) just tell me! I'm open to new ideas. Thanks a lot! Manuel

  • How to have a function with a nullable string parameter in Go?

    - by yuku
    I'm used to Java's String where we can pass null rather than "" for special meanings, such as use a default value. In Go, string is a primitive type, so I cannot pass nil (null) to a parameter that requires a string. I could write the function using pointer type, like this: func f(s *string) so caller can call that function either as f(nil) or // not so elegant temp := "hello"; f(&temp) but the following is unfortunately not allowed: // elegant but disallowed f(&"hello"); What is the best way to have a parameter that receives either a string or nil?

    - by john
    Hi, I got the following example: require 'erb' names = [] names.push( { 'first' => "Jack", 'last' => "Herrington" } ) names.push( { 'first' => "LoriLi", 'last' => "Herrington" } ) names.push( { 'first' => "Megan", 'last' => "Herrington" } ) myname = "John Smith" File.open( ARGV[0] ) { |fh| erb = ERB.new( fh.read ) print erb.result( binding ) accompanied by text.txt <% name = "Jack" %> Hello <%= name %> <% names.each { |name| %> Hello <%= name[ 'first' ] %> <%= name[ 'last' ] %> <% } %> hi, my name is <%= myname %> } it prints nicely to screen. what is the simplest way to output another file: "text2.txt"? thank you!!!

  • How to add custom hooks to controllers in ASP.NET MVC2

    - by Adrian
    Hi, I've just started a new project in ASP.net 4.0 with MVC 2. What I need to be able to do is have a custom hook at the start and end of each action of the controller. e.g. public void Index() { *** call to the start custom hook to externalfile.cs (is empty so does nothing) ViewData["welcomeMessage"] = "Hello World"; *** call to the end custom hook to externalfile.cs (changes "Hello World!" to "Hi World") return View(); } The View then see welcomeMessage as "Hi World" after being changed in the custom hook. The custom hook would need to be in an external file and not change the "core" compiled code. This causes a problem as with my limited knowledge ASP.net MVC has to be compiled. Does anyone have any advice on how this can be achieved? Thanks

  • Problem with istringstream in C++

    - by helixed
    Hello, I'm sure I'm just doing something stupid here, but I can't quite figure out what it is. When I try to run this code: #include <iostream> #include <string> #include <sstream> using namespace std; int main(int argc, char *argv[]) { string s("hello"); istringstream input(s, istringstream::in); string s2; input >> s2; cout << s; } I get this error: malloc: *** error for object 0x100016200: pointer being freed was not allocated *** set a breakpoint in malloc_error_break to debug The only thing I can think of is that I allocated s2 on the stack, but I thought strings manage their own content on the heap. Any help here would be appreciated. Thanks, helixed

  • IFrame causing javascript code to not execute

    - by Claudio Redi
    Does anyone know why this code doesn't work. This means, the alert is NOT fired <iframe/> <script type="text/javascript">alert('hello');</script> While this code with the alert BEFORE the Iframe works perfeclty. This means the alert is fired <script type="text/javascript">alert('hello');</script> <iframe/> Seems that no javascript placed after the iframe is executed, I don't find any logic to this.
