  • Setting Environment Variable for Tomcat 6 Servlet

    - by amaevis
    I'm using Ubuntu's default installation of Tomcat 6. I'm deploying a ROOT.war, and trying to set an environment variable specific to it, i.e. accessible from System.getenv() in the Servlet.init(config). According to the docs (http://tomcat.apache.org/tomcat-6.0-doc/config/context.html), I can specify this in a Context element in conf/Catalina/localhost/ROOT.xml. I've created that with these contents: <Context> <Environment name="FOO" value="bar" type="java.lang.String" override="false"/> </Context> And I've deployed the webapp as usual, i.e. to webapps/ROOT.war. Server.getenv("FOO") in the Servlet.init(config) still returns null. What am I missing?

  • How to free static member variable in C++?

    - by user299831
    Can anybody explain how to free memory of a static member Variable? In my understanding it can only be freed if all the instances of the class are destroyed. I am a little bit helpless at this point... Some Code to explain it: class ball { private: static SDL_Surface *ball_image; }; //FIXME: how to free static Variable? SDL_Surface* ball::ball_image = SDL_LoadBMP("ball.bmp");

  • Troubles with a PHP session variable after form submission

    - by Psyche
    Hello, I'm setting a PHP session variable with a success message for a HTML form that I'm submitting. If there are no form errors, I redirect to the same page (using header()) and display the message from the session variable. Everything is fine until here, but if I access that page again after submission, the message is still there. Is it possible to make it appear only when I redirect after a successful submit? Thank you.

  • Assign query results to MySQL variable

    - by 5un5
    I'm querying a big mysql database with only read privileges, and I'd like to set some slow query results to a variable, 'foo', so I can use them again in other queries. I get, ERROR 1193 (HY000): Unknown system variable '$foo' when I enter: set $foo := (select * from table1 join table2 where bar = 0 group by id); Is there a way to do this with variables, since I don't have privileges to create temporary tables?

  • MySQL using function IN with variable

    - by misanov
    I have problem querying table with variable in IN function. SELECT s.date, (SELECT GROUP_CONCAT(value) FROM value WHERE id_value IN(s.ref_values) ) AS vals FROM stats s ORDER BY s.date DESC LIMIT 1 Where s.ref_values is '12,22,54,15'. I get only one return for first number (12). When I insert that value directly in IN(12,22,54,15) it finds all 4. So, there must be problem with using variable in IN. What am I doing wrong?

    Hi, I'm new to the C# world and I can't find a method to declare read only variable in C# (something like declaring "const" variable in c++). Is there one? I'll give you an example: ... int f() { return x; } // x is not const member ... void g() { int readOnlyVar = f(); // is there a method to declare readOnlyVar as read only or const // Some code in which I want to restrict access to readOnlyVar to read only }

  • Pass a variable from postDispatch() to view instance in Zend Framework

    - by takeshin
    I have a controller plugin with postDispatch() hook, and there I have a $variable. How to pass this variable to the view instance? I tried Zend_Layout::getMvcInstance()->getView(), but this returns new view instance (not the application resource). The same with $bootstrap->getResource('view'). I don't want to pass it as a request param. Now, as a workaround I do it using Zend_Registry. But, is it the best way?

  • What does @@variable mean in Ruby?

    - by Andrew
    What are Ruby variables preceded with double at signs (@@)? My understanding of a variable preceded with an at sign is that it is an instance variable, like this in PHP: PHP version class Person { public $name; public function setName($name) { $this->name = $name; } public function getName() { return $this->name; } } Ruby equivalent class Person def set_name(name) @name = name end def get_name() @name end end What does the double at sign @@ mean, and how does it differ from a single at sign?
