  - by Napalm

  I'm using Eclipse Juno to create jax-ws webservice on WebSphere® Application Server V8.5 Tools. The WebService sometimes are created but most often he fails to create wsdl. For exemplify, i try to create a simple webservice named Web: import javax.jws.WebMethod; import javax.jws.WebService; @WebService public class Web { @WebMethod public String getName() { return "myName"; } } After deploy this webservice and viewing WebSphere administration page not exists any service named WebService. I tried too access the generated WebSphere wsdl from the url localhost:9080/MyProject/WebService/WebService.wsdl but this not exists. My project have a configured MANIFEST file that contains: Manifest-Version: 1.0 UseWSFEP61ScanPolicy: true I'm actually using servlet 3.0 but tried with 2.3. Anyone can help me to do WebSphere approprieate scan annotations of ws-jax and create wsdl on server?

• Please suggest me the best way to design my database.

  - by Raymond Ho

  I have a table named "Pages" and a table named "Categories". Each entry of the table "Pages" is linked to the table "Categories". The "Categories" table have 5 entries, they are: "Car", "Websites", "Technology", "Mobile Phones", and "Interest". So each time I put an entry to the "Pages" table, I need to map it to the "Categories" table so are arranged properly. Here's my table: Pages ______ id [PK] name url Categories ______ id [PK] Categoryname Pages2Categories ______ Pages.id Categories.id So my question is, is this the most efficient way to create this kind of relationships between tables? It seems very amateur

  - by dana

  i have a class named cv,and a class named university, and each user that completes his cv, should choose a University he studyes at.

The data from the Cv class, and from the University class in the same form, and the user can add one or more universities, or no university. (in the same form) How should i do it? Should i use ModelForm? if i have a foreign key in the CV class, and the user is not a student (so he is at zero universities), i may get an referencial integrity error. thanks a lot

• Check if CSS Class exists in StyleSheet using javascript/jQuery

  - by Akhil Sekharan

  Is there a way to check if there is a class named 'some-class-name' in css? For example, I have: <style type="text/css"> .box { position: absolute; left: 150%; } </style> My intention is to randomly assign a class to a div on certain event: var classList = []; //Need to populate this array $('#updateClass').on('click', function() { $('#resultDiv').attr('class',classList[Math.floor((Math.random()*classList.length)+1)]); }); Is it possible to check by JS/jQuery whether a class named 'box' exists in the stylesheet? Thanks.

• What are the other new features of C# 4.0, after dynamic and optional parameters?

  - by Abel

  So, C# 4.0 came out yesterday. It introduced the much-debated dynamic keyword, named and optional parameters. Smaller improvements were the implicit ref and recognizing of indexed and default properties on COM methods, contra- and co-variance (really a .NET CLR feature, not C# only) and... Is that really it? Are dynamic and optional/named params the only real improvements to C#? Or did I miss something? Not that I'm complaining, but it seems a bit meager after C# 2.0 (generics) and C# 3.0 (lambda, LINQ). Maybe the language just reached actual maturity?

• How do I change my current directory from a python script?

  - by misterloogs

  I'm trying to implement my own version of the 'cd' command that presents the user with a list of hard-coded directories to choose from, and the user has to enter a number corresponding to an entry in the list. The program, named my_cd.py for now, should then effectively 'cd' the user to the chosen directory. Example of how this should work: /some/directory $ my_cd.py 1) ~ 2) /bin/ 3) /usr Enter menu selection, or q to quit: 2 /bin $ Currently, I'm trying to 'cd' using os.chdir('dir'). However, this doesn't work, probably because my_cd.py is kicked off in its own child process. I tried wrapping the call to my_cd.py in a sourced bash script named my_cd.sh: #! /bin/bash function my_cd() { /path/to/my_cd.py } /some/directory $ . my_cd.sh $ my_cd ... shows list of dirs, but doesn't 'cd' in the interactive shell Any ideas on how I can get this to work? Is it possible to change my interactive shell's current directory from a python script?

• Porting C++-code from Windows to Unix: systemcalls colliding with name of functions

  - by marvin2k

  Hi I'm porting some crufty C++ Windows-code to Linux, which uses functions called "open" and "close" inside every class... Very bad style, or? Luckily that wasn't a problem in windows, since their systemcalls are named different. When I try to call the systemcalls open() or close() I'm getting some compiler error about "no matching function for call for class:open()". I can't rename all our functions named "class::open" and "class::close" in the whole code, and I have to use open() and close() since I'm working with serial ports. So my question is: How can I tell the compiler, which open I mean? How can I escape or hide the namespace of a class in C++?

• Hierarchy of modules in guice

  - by Niko

  Hi, I'd like to run a unit test where a constant is slightly different than in the standard version. That is, in my default module, the following is bindConstant().annotatedWith(Names.named("number of players")).to(4); but in testing, I'd like to try this line instead: bindConstant().annotatedWith(Names.named("number of players")).to(2); Id like to achieve that without copying all of the rest of the module. What I really want is a "default" module that is "below" a more specialized module, such that in case of conflict, the specialized module wins (instead of throwing an exception, which is what guice does). In essence, my question is: how does anybody arrange for more than one module without lots of code duplication?

• Regarding Authlogic and page redirection.

  - by Paddy

  I am using authlogic for authentication in my Rails app. Have named routes for the frequent actions, viz: map.login "login", :controller = "user_sessions", :action = "new" map.logout "logout", :controller = "user_sessions", :action = "destroy" map.register "register", :controller = "users", :action = "new" map.edit 'user/edit/:id', :controller = "users", :action = "edit" But also in my routes.rb i have these automatically created REST routes too: map.resources :user_sessions map.resources :users The problem now is that a user can login from two different routes. Ex: From, http://localhost/login and also from http ://localhost/user_sessions/new. How do i restrict access only from the named route i have defined and not allow from user_sessions/new?

• Is c++ explicit conversion really that bad?

  - by LoudNPossiblyRight

  My knowledge in c++ at this point is more academic than anything else and in all my reading thus far, the use of explicit conversion with named casts (const_cast, static_cast, reinterpret_cast, dynamic_cast) has come with a big warning label (and it's easy to see why) that pretty much implies explicit conversion is symptomatic of bad design and should only be used as a last resort in desperate circumstances. So i have to ask: Is explicit conversion with named casts really just jury rigging code or is there a more graceful and positive application to this feature? Is there a good example of the latter? Thanks in advance.

• Don't understand multiple parameter declarations in objective-c

  - by Blankman

  can someone clarify this for me: When there’s more than one argument, the arguments are declared within the method name after the colons. Arguments break the name apart in the declaration, just as in a message. For example: - (void)setWidth:(float)width height:(float)height; So in the above: method is for instance variables returns void parameter#1 is a float, named width. parameter#2 is a float,named height. But why is it hieght:(float)height; and not just: - (void)setWidth: (float)width (float)height;

• C++: retrieve map values and insert into second map

  - by donalmg

  Hi, I have one map within one header file class: class One { // code typedef map<string, int> MapStrToInt inline MapStrToInt& GetDetails(unsigned long index) { return pData[index]; } // populate pData.... private: MapStrToInt *pData; }; And a second class which implements another map and wants to get the first 10 details from the class One's map. class Two { // code One::MapStrToInt pDataTen; int function1() { for (int i =0; i < 10; i ++) { One::MapStrToInt * pMap = &(One::GetDetails(i)); pDataTen.insert(pair<string, int>(pMap->first,pMap->second)); } } When I compile this, it states that pMap: has no member named 'first' has no member named 'second' Any suggestions?

• Problem with url_for in ActionMailer template

  - by macek

  I'm attempting to provide a confirmation link in my user welcome email and I'm getting the following Rails error: Need controller and action! It makes a fuss about this line: <p>Please take a moment to activate your account by going to: <%= link_to confirm_user_url(:id => @user.confirmation_code) %>.</p> In my development.rb environment, I have the following line: config.action_mailer.default_url_options = { :host => "localhost", :port => 3000 } There's no problem with the @user variable. I've tested the email with things like @user.username and @user.confirmation_code. I'm only getting trouble with url_for and named routes like confirm_user_url. When I check my routes with rake routes, confirm_user shows up, so it's not an issue with the named route not existing. I can't seem to figure it out. What gives?

• Reference table values in a war against magic numbers

  - by Alex N.

  This question bugged me for years now and can't seem to find good solution still. I working in PHP and Java but it sounds like this maybe language-agnostic :) Say we have a standard status reference table that holds status ids for some kind of entity. Further let's assume the table will have just 5 values, and will remain like this for a long time, maybe edited occasionally with addition of a new status. When you fetch a row and need to see what status it is you have 2 options(as I see it at least) - put it straight ID values(magic numbers that is) or use a named constant. Latter seem much cleaner, the question though is where those named constants should leave? In a model class? In a class that uses this particular constant? Somewhere else?

• Syncronizing indices of function pointer table to table contents

  - by Thomas Matthews

  In the embedded system I'm working on, we are using a table of function pointers to support proprietary Dynamic Libraries. We have a header file that uses named constants (#define) for the function pointer indices. These values are used in calculating the location in the table of the function's address. Example: *(export_table.c)* // Assume each function in the table has an associated declaration typedef void (*Function_Ptr)(void); Function_Ptr Export_Function_Table[] = { 0, Print, Read, Write, Process, }; Here is the header file: *export_table.h* #define ID_PRINT_FUNCTION 1 #define ID_READ_FUNCTION 2 #define ID_WRITE_FUNCTION 3 #define ID_PROCESS_FUNCTION 4 I'm looking for a scheme to define the named constants in terms of their location in the array so that when the order of the functions changes, the constants will also change. (Also, I would like the compiler or preprocessor to calculate the indices to avoid human mistakes like typeo's.)

• Fetching a result twice with deferend name

  - by user1799842

  I have 1 table with tasks named opentask:columns: id,title,description,expires,creator_id,creator_name, executer_id, executer_name, priority_id, status_id1 table with users named user: with columns: user_id, username What I want is to create a query where there will be all columns from opentask table where the executer_id will be equal to the user_id of user table AND the creator_id will be equal to the user_id again. This creates a confusion because the first equality excludes the second.So I need somehow to create a query where I will include the usernames for the executer with something like where "opentask.executer_id=user_user_id" and at the same time I will include the username again (as a differend name?) for the creator with something like "where opentask.executer_id=user_user_id"So I try this, which of course I know that is missing something, can you help? SELECT DISTINCT id, title, description, expires, creator_id, executer_id, oc_opentask.priority_id, oc_opentask.status_id, priority_name, status_name, user_id, username, (SELECT username FROM oc_opentask, oc_user WHERE oc_opentask.creator_id=oc_user.user_id) AS username2 FROM oc_opentask, oc_opentask_priority, oc_user, oc_opentask_status WHERE oc_opentask.priority_id=oc_opentask_priority.priority_id AND oc_opentask.executer_id=oc_user.user_id AND oc_opentask.status_id=oc_opentask_status.status_id ORDER BY oc_opentask.expires DESC

• mysql twitter/facebook like status feed

  - by barjonah

  Hi, I have two tables. One named status like this... user_id | status --------+----------- 1 | random status from user 1 2 | random status from user 2 3 | random message from user 3 4 | staus from user 4 1 | second status for user1 etc... and another named users_following like this... user_id | is_following --------+----------- 1 | 2 1 | 3 2 | 1 3 | 2 meaning that user 1 is following both users 2 and 3 etc... So, let's say I chose user 1. What is the best query (performance wise) to show the status updates of users that user 1 is following, in this case users 2 and 3 currently I have something like SELECT * from status WHERE user_id IN(SELECT is_following FROM users_following WHERE user_id='1') LIMIT 0,5 but I don't think this is good for performance if a user was following thousands+ of users
