  • Eclipse: How to convert a web project into an AspectJ project and weave and run it using the AJDT pl

    - by Kent
    What I want to do: I want to use the @Configured annotation with Spring. It requires AspectJ to be enabled. I thought that using the AJDT plugin for compile time weaving would solve this problem. Before installing the plug in the dependencies which were supposed to be injected into my @Configured object remained null. What I have done: Installed the AJDT: AspectJ Development Tools plug in for Eclipse 3.4. Right clicked on my web project and converted it into a AspectJ project. Enabled compile time weaving. What doesn't work: When I start the Tomcat 6 server now, I get an exception*. Other information: I haven't configured anything in the AspectJ Build and AspectJ Compiler parts of the project properties. JDT Weaving under Preferences says weaving is enabled. I still have Java build path and Java Compiler under project properties. And they look like I previously configured them (while the above two new entries are not configured). The icon of my @Configured object file looks like any other file (i.e. no indication of any aspect or such, which I think there should be). The file name is MailNotification.java (and not .aj), but I guess it should still work as I'm using a Spring annotation for AspectJ? I haven't found any tutorial or similar which teaches: How to turn a Spring web application project into an AspectJ project and weave aspects into the files using the AJDT plugin, all within Eclipse 3.4. If there is anything like that out there I would be very interested in knowing about it. What I would like to know: Where to go from here? I just want to use the @Configured annotation of Spring. I'm also using @Transactional which I think also needs AspectJ. If it is possible I would like to study AspectJ as little as possible as long as my needs are met. The subject seems interesting, but huge, all I want to do is use the above two mentioned Spring annotations. *** Exception when Tomcat 6 is started: Caused by: java.lang.IllegalStateException: ClassLoader [org.apache.catalina.loader.WebappClassLoader] does NOT provide an 'addTransformer(ClassFileTransformer)' method. Specify a custom LoadTimeWeaver or start your Java virtual machine with Spring's agent: -javaagent:spring-agent.jar at org.springframework.context.weaving.DefaultContextLoadTimeWeaver.setBeanClassLoader(DefaultContextLoadTimeWeaver.java:82) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1322) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:473) ... 41 more

  • iPhone backup & restore does not restore our app's data on rare occasions

    - by Michael Waterfall
    We have an iPhone app with several thousand users, and we've had one or two users saying that after a full backup & restore procedure within iTunes, the data for our app was lost. All the data (photos & SQLite DB) are stored in the documents area of the app. I've tested this thoroughly with our devices and it works absolutely fine. Can anyone think of a reason for this, or has anyone experienced this before?

  • STUN, TURN, ICE library for Java.

    - by Hemeroc
    I need to establish a P2P UDP and TCP Connection between two Users. Both of them are behind a NAT. A little research leads me to STUN, TURN and ICE. Is there any Java solution (library) except jSTUN which seems to work only on UDP. And TURN, ICE is much better for the symmetric NAT Problem.

  • jQuery tabs using radio buttons instead of list navigation

    - by caleb
    I'm following a tutorial to create a simple jquery tabs show/hide content. Wondering if there's a way to re-engineer it to use a list of radio buttons instead of a list? Tutorial here: http://www.sohtanaka.com/web-design/simple-tabs-w-css-jquery/ My js: $(".tab_content").hide(); //Hide all content $("ul.tabs li:first").addClass("active").show(); //Activate first tab $(".tab_content:first").show(); //Show first tab content //On Click Event $("ul.tabs li").click(function() { $("ul.tabs li").removeClass("active"); //Remove any "active" class $(this).addClass("active").children("input[@type=radio]").click(); //Add "active" class to selected tab $(".tab_content").hide(); //Hide all tab content var activeTab = "#" + $(this).children("input").attr("value"); //Find the href attribute value to identify the active tab + content $(activeTab).fadeIn(); //Fade in the active ID content return false; }); My HTML: <ul class="tabs"> <li><input type="radio" name="card" id="one" value="gallery" /> <label for="one">gallery</label></li> <li><input type="radio" name="card" id="two" value="submit" /> <label for="two">submit</label></li> <li><input type="radio" name="card" id="three" value="resources" /> <label for="three">resources</label></li> <li><input type="radio" name="card" id="four" value="contact" /> <label for="four">contact</label></li> </ul> <div class="tab_container"> <div id="gallery" class="tab_content"> <h2>Gallery</h2> </div> <div id="submit" class="tab_content"> <h2>Submit</h2> </div> <div id="resources" class="tab_content"> <h2>Resources</h2> </div> <div id="contact" class="tab_content"> <h2>Contact</h2> </div> </div> I'm able to actively select the radio button within the list, but not activate the actual div.

  • Nh.Burrow with WCF

    - by Jochen
    Hello, After implementing Nh.Burrow in an asp.net application, I was wondering how to do it for a WCF-service. My first idea was to put a the BurrowFramework().InitWorkSpace(); in each method and set the InstanceContextMode to per Call on these methods. Now I have two questions: Are there better methods to combine Nh.Burrow with WCF? Is there a way to create and use a Long Burrow Conversation with WCF? Regards, Jochen

  • Writing preprocessor directives to get string

    - by Dave18
    Can you write preprocessor directives to return you a std::string or char*? For example: In case of integers: #define square(x) (x*x) int main() { int x = square(5); } I'm looking to do the same but with strings like a switch-case pattern. if pass 1 it should return "One" and 2 for "Two" so on..

  • Do any JS implementations currently support (or have support on the roadmap for) fast, vectorized op

    - by agnoster
    I'd like to do a bit of matrix/vector arithmetic in JavaScript, and was wondering if any browsers or other JS implementations actually have support for vectorized operations, for instance for quickly summing the entries of two Arrays (or summing, or whatever). Even if that currently doesn't mean it compiles down to vectorized operations, at least some language support would be nice for when it does get implemented - I'd take the existence of functions or syntax to support it as a step in the right direction. (Understandably, "vectorization javascript" searches are pretty much all about graphics and SVG.)

  • I want to better organize my website files, but I can access the .php files using the folder heirarc

    - by Sergio Tapia
    For example, to access a page in my search folder, I have to write: mywebsite.tld/search/searchJob.php I don't want users to have to write down folder structure and whatnot. What can I do to change this? OR, is there a better way to organize my files? Because I'm only two pages in and I decided to move some files and got lost in the heirarchy (that's why I moved them like in the picture).

    How in SQL could you "zip" together records in separate tables (à la the UNIX paste(1) utility)? For example, assuming two tables, A and B, like so: A B ======== ==== Harkness unu Costello du Sato tri Harper Jones How could you produce a single result set NAME | NUM =============== Harkness | unu Costello | du Sato | tri Harper | NULL Jones | NULL ?

  • Question about PE/COFF file formats - ECOFF, ANON, and BIGOBJ

    - by Zain
    Hi, I've peen looking at the PE/COFF format and it seems to be missing a few things about extensions to the format. Specifically, I'm trying to learn about ECOFF and ANON objects. from what I can tell, those're just two names for the same thing, which is also known as a BIGOBJ. The BIGOBJ allows you to create, surprise surprise, larger object files than the format otherwise allows. Can anyone confirm or correct this? Thanks

  • How can I resolve circular dependencies in Funq IoC?

    - by Rickard
    I have two classes which I need to reference each other. class Foo { public Foo(IBar bar) {} } class Bar { public Bar(IFoo foo) {} } When I do: container.RegisterAutoWiredAs<Foo, IFoo>(); container.RegisterAutoWiredAs<Bar, IBar>(); and when I try to resolve either interface I get a circular dependency graph which results in an eternal loop. Is there an easy way to solve this in Funq or do you know of a workaround?

  • error C2784: Could not deduce template argument

    - by atch
    Hi guys, Still fighting with templates. In this example, despite the fact that is copied straight from a book I'm getting the following error message: Error 2 error C2784: 'IsClassT<T>::One IsClassT<T>::test(int C::* )' : could not deduce template argument for 'int C::* ' from 'int'. This is an example from a book Templates - The Complete Guide. (I work with Visual Studio 2010 RC). template<typename T> class IsClassT { private: typedef char One; typedef struct { char a[2]; } Two; template<typename C> static One test(int C::*); template<typename C> static Two test(…); public: enum { Yes = sizeof(IsClassT<T>::test<T>(0)) == 1 }; enum { No = !Yes }; }; class MyClass { }; struct MyStruct { }; union MyUnion { }; void myfunc() { } enum E {e1} e; // check by passing type as template argument template <typename T> void check() { if (IsClassT<T>::Yes) { std::cout << " IsClassT " << std::endl; } else { std::cout << " !IsClassT " << std::endl; } } // check by passing type as function call argument template <typename T> void checkT (T) { check<T>(); } int main() { /*std::cout << "int: "; check<int>(); */ std::cout << "MyClass: "; check<MyClass>(); } And although I know roughly what's going on in this example I cannot fix this error. Thanks for help.

  • MS Access group development

    - by Hubidubi
    We are planning to redesign quite a huge MS Access application. Is there any way to work concurently on the same application or is it possible to merge two seperate instance of the same file (not the data, but the forms and code). Now Access contains the data, but in the future version MySQL will host the data and Access will be only the frontend (via ODBC)
