  • Spring Custom Filter Problem?

    - by mr.lost
    greetings all,iam using spring security 3 and i want to perform some logic(saving some data in the session) when the user is visiting the site and he's remembered so i extended the GenericFilterBean class and performed the logic in the doFilter method then complete the filter chain by calling the chain.doFilter method,and then inserted that filter after the remember me filter in the security.xml file? but there's a problem is the filter is executed on each page even if the user is remembered or not is there's something wrong with the filter implementation or the position of the filter? and i have a simple question,is the filter chain by default is executed on each page? and when making a custom filter should i add it to the web.xml too? the filter class: package projects.internal; import java.io.IOException; import javax.servlet.FilterChain; import javax.servlet.ServletException; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.security.core.Authentication; import org.springframework.security.core.context.SecurityContextHolder; import org.springframework.web.filter.GenericFilterBean; import projects.ProjectManager; public class rememberMeFilter extends GenericFilterBean { private ProjectManager projectManager; @Autowired public rememberMeFilter(ProjectManager projectManager) { this.projectManager = projectManager; } @Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { System.out.println("In The Filter"); Authentication auth = (Authentication) SecurityContextHolder .getContext().getAuthentication(); HttpServletResponse response = ((HttpServletResponse) res); HttpServletRequest request = ((HttpServletRequest) req); // if the user is not remembered,do nothing if (auth == null) { chain.doFilter(request, response); } else { // the user is remembered save some data in the session System.out.println("User Is Remembered"); chain.doFilter(request, response); } } } the security.xml file: <beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd"> <global-method-security pre-post-annotations="enabled"> </global-method-security> <http use-expressions="true" > <remember-me data-source-ref="dataSource"/> <intercept-url pattern="/" access="permitAll" /> <intercept-url pattern="/images/**" filters="none" /> <intercept-url pattern="/scripts/**" filters="none" /> <intercept-url pattern="/styles/**" filters="none" /> <intercept-url pattern="/p/login" filters="none" /> <intercept-url pattern="/p/register" filters="none" /> <intercept-url pattern="/p/forgot_password" filters="none" /> <intercept-url pattern="/p/**" access="isAuthenticated()" /> <custom-filter after="REMEMBER_ME_FILTER" ref="rememberMeFilter" /> <form-login login-processing-url="/j_spring_security_check" login-page="/p/login" authentication-failure-url="/p/login?login_error=1" default-target-url="/p/dashboard" authentication-success-handler-ref="myAuthenticationHandler" always-use-default-target="false" /> <logout/> </http> <beans:bean id="myAuthenticationHandler" class="projects.internal.myAuthenticationHandler" /> <beans:bean id="rememberMeFilter" class="projects.internal.rememberMeFilter" > </beans:bean> <authentication-manager alias="authenticationManager"> <authentication-provider> <password-encoder hash="md5" /> <jdbc-user-service data-source-ref="dataSource" /> </authentication-provider> </authentication-manager> </beans:beans> any help?

  • Overlay 2d weapon sprite over character sprite ?

    - by Mr.Gando
    Hello, I'm working on a game where my character needs to be able to have different weapons. For that I think that somehow overlaying the weapon over the moving sprite would be the correct choice, but I'm not sure about how could I do this. Assuming my Character spritesheet looks like this: And my preliminar weapon spritesheet ( haven't decided on a fixed square size for the weapon yet ), looks like this: How would you make the overlay to set the weapon correctly over the character hand for each of his frames? I know that one way would be just to have a weapon frame the same size as my character sprites, and overlay those too, but I think that if the game has way too much weapons (say 15 different kinds of one hand weaps) this could get pretty insane ( having one weapon sprite sheet the same size as the character sprite sheet for each type of weapon ) Do you guys have any advice on how to implement this? (supporting overlaying the weapon sprites over the character sprites) Thanks!

Anyone got a solution for me?

  • Finding out whether a DirectInput device supports XInput (with mingw/gcc)

    - by Mr. Wonko
    I'm working on an input system, wrapping DirectInput and XInput. Currently XInput devices are enumerated twice, once as XInput and once as DirectInput (since they support both). How can I find out if a given DirectInput device also supports XInput? There is this MSDN page on the topic, but it requires wbemidl.h and wmsstd.h which aren't available in mingw/gcc (and for some reason I want to avoid msvc - probably by habit). I don't think blacklisting device names/guids is a good solution, but is there a better one? Thanks.

  • What is the right approach to checksumming UDP packets

    - by mr.b
    I'm building UDP server application in C#. I've come across a packet checksum problem. As you probably know, each packet should carry some simple way of telling receiver if packet data is intact. Now, UDP already has 2-byte checksum as part of header, which is optional, at least in IPv4 world. Alternative method is to have custom checksum as part of data section in each packet, and to verify it on receiver. My question boils down to: is it better to rely on (optional) checksum in UDP packet header, or to make a custom checksum implementation as part of packet data section? Perhaps the right answer depends on circumstances (as usual), so one circumstance here is that, even though code is written and developed in .NET on Windows, it might have to run under platform-independent Mono.NET, so eventual solution should be compatible with other platforms. I believe that custom checksum algorithm would be easily portable, but I'm not so sure about the first one. Any thoughts? Also, shouts about packet checksumming in general are welcome.

  • Chipmunk Physics or Box2D for C++ 2D GameEngine ?

    - by Mr.Gando
    Hello, I'm developing what it's turning into a "cross-platform" 2D Game Engine, my initial platform target is iPhone OS, but could move on to Android or even some console like the PSP, or Nintendo DS, I want to keep my options open. My engine is developed in C++, and have been reading a lot about Box2D and Chipmunk but still I can't decide which one to use as my Physics Middleware. Chipmunk appears to have been made to be embedded easily, and Box2D seems to be widely used. Chipmunk is C , and Box2D is C++, but I've heard the API's of Box2D are much worse than chipmunk's API's. For now I will be using the engine shape creation and collision detection features for irregular polygons (not concave). I value: 1) Good API's 2) Easy to integrate. 3) Portability. And of course if you notice anything else, I would love to hear it. Which one do you think that would fit my needs better ?

  • Why are there so many Database Management Systems?

    - by mr.bio
    Why are there so many Database management systems? I am not an DB expert and I've never thought about using another Database other than mySQL. Programming languages offer different paradigms, so it makes sense to choose a specific language for your purpose. Question What are the factors in choosing a specific Database management system ?

  • Can iFrame Scrollbars be skinned in webkit?

    - by Mr. Bamboo
    It's pretty well known by now that you can style scrollbars using the webkit specific CSS tags (::-webkit-scrollbar-button:start:decrement, ::-webkit-scrollbar-button:end:increment, etc. ). However, I've noticed that I cannot style the scrollbars attached to iFrames. Question: Is there a way to access and style the scrollbars on the iFrame using webkit? (Yes, I've actually got a particular scenario where I'd like to be able to do this.) Thanks much in advance for any help!
