    - by Massimo Zampieri
    Hi i have a problem with the curl. I watched an old post Remote Login not Working With Curl, but it not work. I followed baba's advice but the code enter in the if statement. Sorry for my bad english. Can anyone help me? This is the code: $url="http://hipfile.com/"; $urllog="http://hipfile.com/login.html"; $postdata = "login=bnnoor&password=########&op=login"; $ch = curl_init(); curl_setopt ($ch, CURLOPT_URL, $url); curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); curl_setopt ($ch, CURLOPT_TIMEOUT, 60); curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_REFERER, $urllog); curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata); curl_setopt ($ch, CURLOPT_POST, 1); $result = curl_exec ($ch); if (!$result) { $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); curl_close($ch); // make sure we closeany current curl sessions die($http_code.'

  • Python's asyncore to periodically send data using a variable timeout. Is there a better way?

    - by Nick Sonneveld
    I wanted to write a server that a client could connect to and receive periodic updates without having to poll. The problem I have experienced with asyncore is that if you do not return true when dispatcher.writable() is called, you have to wait until after the asyncore.loop has timed out (default is 30s). The two ways I have tried to work around this is 1) reduce timeout to a low value or 2) query connections for when they will next update and generate an adequate timeout value. However if you refer to 'Select Law' in 'man 2 select_tut', it states, "You should always try to use select() without a timeout." Is there a better way to do this? Twisted maybe? I wanted to try and avoid extra threads. I'll include the variable timeout example here: #!/usr/bin/python import time import socket import asyncore # in seconds UPDATE_PERIOD = 4.0 class Channel(asyncore.dispatcher): def __init__(self, sock, sck_map): asyncore.dispatcher.__init__(self, sock=sock, map=sck_map) self.last_update = 0.0 # should update immediately self.send_buf = '' self.recv_buf = '' def writable(self): return len(self.send_buf) > 0 def handle_write(self): nbytes = self.send(self.send_buf) self.send_buf = self.send_buf[nbytes:] def handle_read(self): print 'read' print 'recv:', self.recv(4096) def handle_close(self): print 'close' self.close() # added for variable timeout def update(self): if time.time() >= self.next_update(): self.send_buf += 'hello %f\n'%(time.time()) self.last_update = time.time() def next_update(self): return self.last_update + UPDATE_PERIOD class Server(asyncore.dispatcher): def __init__(self, port, sck_map): asyncore.dispatcher.__init__(self, map=sck_map) self.port = port self.sck_map = sck_map self.create_socket(socket.AF_INET, socket.SOCK_STREAM) self.bind( ("", port)) self.listen(16) print "listening on port", self.port def handle_accept(self): (conn, addr) = self.accept() Channel(sock=conn, sck_map=self.sck_map) # added for variable timeout def update(self): pass def next_update(self): return None sck_map = {} server = Server(9090, sck_map) while True: next_update = time.time() + 30.0 for c in sck_map.values(): c.update() # <-- fill write buffers n = c.next_update() #print 'n:',n if n is not None: next_update = min(next_update, n) _timeout = max(0.1, next_update - time.time()) asyncore.loop(timeout=_timeout, count=1, map=sck_map)

  • JAXB, how to marshal without a namespace

    - by Alvin
    I have a fairly large repetitive XML to create using JAXB. Storing the whole object in the memory then do the marshaling takes too much memory. Essentially, my XML looks like this: <Store> <item /> <item /> <item /> ..... </Store> Currently my solution to the problem is to "hard code" the root tag to an output stream, and marshal each of the repetitive element one by one: aOutputStream.write("<?xml version="1.0"?>") aOutputStream.write("<Store>") foreach items as item aMarshaller.marshall(item, aOutputStream) end aOutputStream.write("</Store>") aOutputStream.close() Somehow the JAXB generate the XML like this <Store xmlns="http://stackoverflow.com"> <item xmlns="http://stackoverflow.com"/> <item xmlns="http://stackoverflow.com"/> <item xmlns="http://stackoverflow.com"/> ..... </Store> Although this is a valid XML, but it just look ugly, so I'm wonder is there any way to tell the marshaller not to put namespace for the item elements? Or is there better way to use JAXB to serialize to XML chunk by chunk?

  • Offline Mapping API

    - by Aaron M
    Are there any services available that allow me to manipulate maps in an offline setting? I am working on a project that requires me to take a map and based on features on the map, generate a game world. I have looked at a few of the API's for different providers: Google, ms, etc. The API's I looked seem to be strictly showing a user a map. I am looking for something that allows me to create a derivative of a map (the Gameworld), that will never be seen by the public, and is only used by the game engine. However one caveat is that I would like to be able to link the derivative created for use by the game engine, with something I can show the user. As an example. Think of a cross country racing sim. Users cannot control the vehicles directly in this game, they can only control the cars setup, driver, etc. I create a gameworld from a map. The gameworld data (driver position, etc) is overlayed onto a real map. A race might last several days. The only interaction users have with the real map is viewing their position on the map, and where they are in relation to the others. I don't want to violate the terms of the API here. I read Googles API TOS, and it seems to me that creating the gameworld would violdate their TOS. The features I really need are the following The ability to locate a specific place on the map by lat/long The ability/rights to grab those maps and save them as an image file temporarily for processing The ability/rights to store a gameworld that is based on the real map The ability to show a user a map with an overlay (this is optional. I can use googles API, or any other one that supports lat/long.)

  • For loop in Javascript runs only once

    - by user592748
    Here is my code. I do not quite understand why the for loop runs only once, both inner and outer. nodeList.length and innerNodeList.length show appropriate values when I generate alert messages. I see that both i and j do not increment beyond 0. Kindly point out anything wrong with the code. function getCategoryElements() { var newCategoryDiv = document.getElementById("category"); var nodeList = newCategoryDiv.childNodes; for (var i = 0; i < nodeList.length; ++i) { var innerNodeList = nodeList[i].childNodes; alert("innerNodeList Length" + innerNodeList.length.toString()); for (var j = 0; j < innerNodeList.length; ++j) { if (innerNodeList[j].nodeName == "SELECT") { alert("inside select Node value " + innerNodeList[j].nodeValue.toString()); document.getElementById("newCategories").value = document.getElementById("newCategories").value + '<%=delimiter%>' + innerNodeList[j].nodeValue; } else if (innerNodeList[j].nodeName == "TEXTAREA") { document.getElementById("newCategoriesData").value = document.getElementById("newCategoriesData").value + '<%=delimiter%>' + innerNodeList[j].nodeValue; } } } }

  • Reflecting over classes in .NET produces methods only differing by a modifier

    - by mrjoltcola
    I'm a bit boggled by something, I hope the CLR gearheads can help. Apparently my gears aren't big enough. I have a reflector utility that generates assembly stubs for Cola for .NET, and I find classes have methods that only differ by a modifier, such as virtual. Example below, from Oracle.DataAccess.dll, method GetType(): class OracleTypeException : System.SystemException { virtual string ToString (); virtual System.Exception GetBaseException (); virtual void set_Source (string value); virtual void GetObjectData (System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context); virtual System.Type GetType (); // here virtual bool Equals (object obj); virtual int32 GetHashCode (); System.Type GetType (); // and here } What is this? I have not been able to reproduce this with C# and it causes trouble for Cola as it thinks GetType() is a redefinition, since the signature is identical. My method reflector starts like this: static void DisplayMethod(MethodInfo m) { if ( // Filter out things Cola cannot yet import, like generics, pointers, etc. m.IsGenericMethodDefinition || m.ContainsGenericParameters || m.ReturnType.IsGenericType || !m.ReturnType.IsPublic || m.ReturnType.IsArray || m.ReturnType.IsPointer || m.ReturnType.IsByRef || m.ReturnType.IsPointer || m.ReturnType.IsMarshalByRef || m.ReturnType.IsImport ) return; // generate stub signature // [snipped] }

  • What is the form_for syntax for nested resources?

    - by Kris
    I am trying to create a form for a nested resource. Here is my route: map.resources :websites do |website| website.resources :domains end Here are my attempts and the errors: <% form_for(@domain, :url => website_domains_path(@website)) do | form | %> <%= form.text_field :name %> # ArgumentError: wrong number of arguments (1 for 0) # form_helper.rb:290:in 'respond_to?' # form_helper.rb:290:in 'apply_form_for_options!' # form_helper.rb:277:in 'form_for' <% form_for([@website, @domain]) do | form | %> <%= form.text_field :name %> # ArgumentError: wrong number of arguments (1 for 0) # form_helper.rb:290:in 'respond_to?' # form_helper.rb:290:in 'apply_form_for_options!' # form_helper.rb:277:in 'form_for' <% form_for(:domain, @domain, :url => website_domains_path(@website)) do | form | %> <%= form.text_field :name %> # ArgumentError: wrong number of arguments (1 for 0) # wrapper.rb:14:in 'respond_to?' # wrapper.rb:14:in 'wrap' # active_record_helper.rb:174:in 'error_messages_for' <% form_for(:domain, [@website, @domain]) do | form | %> <%= form.text_field :name %> # UndefinedMethodError 'name' for #<Array:0x40fa498> I have confirmed both @website and @domain contain instances of the correct class.

  • Some clarification needed about synchronous versus asynchronous asio operations

    - by Old newbie
    As far as I know, the main difference between synchronous and asynchronous operations. I.e. write() or read() vs async_write() and async_read() is that the former, don't return until the operation finish -or error-, and the last ones, returns inmediately. Due the fact that the asynchronous operations are controlled by an io_service.run() that does not finish until the controlled operations has finalized. It seems to me that in sequencial operations as those involved in TCP/IP connections with protocols such as POP3, in which the operaton is a sequence such as: C: <connect> S: Ok. C: User... S: Ok. C: Password S: Ok. C: Command S: answer C: Command S: answer ... C: bye S: <close> The difference between synchronous/asynchronous opperatons does not make much sense. Of course, in both operations there is allways the risk that the program flow stops indefinitely by some circunstance -there the use of timers-, but I would like know some more authorized opinions in this matter. I must admit that the question is rather ill-defined, but I like hear some advices about when use one or other, because I've problems in debugging with MS Visual Studio, asynchronous SSL operations in a POP3 client in wich I'm working now -about some of who surely I would write here soon-, and sometimes think that perhaps is a bad idea use asynchronous in this. Not to say that I'm an absolute newbie with this librarys, that additionally to the difficult with the idioma, and some obscure concepts in the STL, must suffer the brevity of the asio documentation.

  • Possible to capture all events in a web browser?

    - by David
    I am working on a pet project and am at the research stage. Quick summary I am trying to intercept all form submits, onclick, and every single keydown. My library of choice is either jquery, or jquery + prototypejs. I figure I can batch up the events into a queue/stack and send it back to the server in time interval batches to keep performance relatively stable. Concerns Form submits and change's would be relatively simple.. Something like $("form :inputs").bind("change", function() { ... record event... }); But how to ensure I get precedence over the applications handlers as I have a habit of putting return false on a lot of my form handlers when there is a validation issue. As I understand it, that effectively stops the event in its tracks. My project For my smaller remote clients I will put their products onto a VPS or run it in my home data center. Currently I use a basic authentication system, given a username/password they see the website and then hopefully send me somewhat sane notes on what is broken or should be tweaked. As a better solution, I've written a simple proxy web server that does the above but allows me to have one DNS entry and then depending on credentials it makes an internal request relaying headers and re-writing URLS as needed. Every single html/text or application/* request is compressed and shoved into a sqlite table so I can partially replay what they've done. Now I am shifting to the frontend and would like to capture clicks, keydown's, and submits on everything on the page.

  • CKEditor doesn't apply inline styles to links

    - by jomanlk
    I'm using ckeditor version 3 as a text editor to create markup to be sent through email. This means that I have to have all the styles inline and anything that needs to be styled will definitely need the style applied. I'm currently using addStylesSet to generate custom styles that can be applied to elements. The problem I have is that although this works on most elements, styles don't seem to be applied to <a> <ol> <ul> and <li> I really need to be able to apply inline styles to these elements as well. I've been looking at the examples on the ckeditor site, but even they just seem to be wrapping a <span> around the link. Is there anyway I can apply inline styles to <a> tags or failing that, can I just give ckeditor a bunch of classes that can be applied to any tag (Like TinyMCE does with it's link to an external css file)? so that I can at least do a textreplace on them to get the styles inline? I haven't pasted any code here because it's exactly the same as what's been done on the ckeditor site.

  • Advanced All In One .NET Framework

    - by alfredo dobrekk
    Hi, i m starting a new project that would basically take input from user and save them to database among about 30 screens, and i would like to find a framework that will allow the maximum number of these features out of the box : .net c#. windows form. unit testing continuous integration screens with lists, combo boxes, text boxes, add, delete, save, cancel that are easy to update when you add a property to your classes or a field to your database. auto completion on controls to help user find its way use of an orm like nhibernate easy multithreading and display of wait screens for user easy undo redo tabbed child windows search forms ability to grant access to some functionnalities according to user profiles mvp/mvvm or whatever design patterns either some code generation from database to c# classe or generation of database schema from c# classes some kind of database versioning / upgrade to easily update database when i release patches to application once in production automatic control resizing code metrics analysis some code generator i can use against my entities that would generate some rough form i can rearrange after code documentation generator ... Any ideas ? I know its lot but i really would like to use existing code to build upon so i can focus on business rules. Could splitting the requirements on 3 or 4 existing open source framework be possible ? Do u have any suggestion to add to the list before starting ? What open source tools would u use to achieve these ?

  • Using twig variable to dynamically call an imported macro sub-function

    - by Chausser
    I am attempting if use a variable to call a specific macro name. I have a macros file that is being imported {% import 'form-elements.html.twig' as forms %} Now in that file there are all the form element macros: text, textarea, select, radio etc. I have an array variable that gets passed in that has an elements in it: $elements = array( array( 'type'=>'text, 'value'=>'some value', 'atts'=>null, ), array( 'type'=>'text, 'value'=>'some other value', 'atts'=>null, ), ); {{ elements }} what im trying to do is generate those elements from the macros. they work just fine when called by name: {{ forms.text(element.0.name,element.0.value,element.0.atts) }} However what i want to do is something like this: {% for element in elements %} {{ forms[element.type](element.name,element.value,element.atts) }} {% endfor %} I have tried the following all resulting in the same error: {{ forms["'"..element.type.."'"](element.name,element.value,element.atts) }} {{ forms.(element.type)(element.name,element.value,element.atts) }} {{ forms.{element.type}(element.name,element.value,element.atts) }} This unfortunately throws the following error: Fatal error: Uncaught exception 'LogicException' with message 'Attribute "value" does not exist for Node "Twig_Node_Expression_GetAttr".' in Twig\Environment.php on line 541 Any help or advice on a solution or a better schema to use would be very helpful.

  • symfony doctrine build-sql error

    - by user313571
    I have some big problems with symfony and doctrine at the beginning of a new project. I have created database diagram with mysql workbench, inserted the sql into phpmyadmin and then I've tried symfony doctrine:build-schema to generate the YAML schema. It generates a wrong schema (relations don't have on delete/on update) and after this I've tried symfony doctrine:build --sql and symfony doctrine:insert-sql The insert-sql statement generates error (can't create table ... failing query alter table add constraint ....), so I've decided to take a look over the generated sql and I've found out some differences between the sql generated from mysql workbench (which works perfect, including relations) and the sql generated by doctrine. I'll be short from now: I have to tables, EVENT and FORM and a 1 to n relation (each event may have multiple forms) so the correct constraint (generated with workbench) is ALTER TABLE `form` ADD CONSTRAINT `fk_form_event1` FOREIGN KEY (`event_id`) REFERENCES `event` (`id`) ON DELETE CASCADE ON UPDATE CASCADE; doctrine generated statement is: ALTER TABLE event ADD CONSTRAINT event_id_form_event_id FOREIGN KEY (id) REFERENCES form(event_id); It's totally reversed and I am sure here is the error. What should I do? It's also correct like this?

  • ASP.NET MVC 2 - How do I use DropDownListFor ?

    - by SLC
    I have a simple model / view with things like Username, Password etc. and use helpers fine to hook it up. I now have a field called "NumberOfChildren". I want to store a number in it (int) and I want it render a dropdown box containing "None", "1", "2" etc. My thoughts would be that the model would have a list or a method that returns a list, so I can specify the values such as NumberOfChildren_List that I put the data into, and then DropDownListFor pulls that list and renders it, matching the value to the value of the item in the dropdown. However after spending about 30 minutes on trying to figure out how on earth it works, I gave up and decided to ask here. Any ideas? Edit: Here's some code... <%: Html.DropDownListFor(m => m.NumberOfChildren, new SelectList(Model.NumberOfChildrenListValues))%> and in the model [Required] [DisplayName("How many children do you have?")] public string NumberOfChildren { get; set; } public IEnumerable<string> NumberOfChildrenListValues { get { List<string> list = new List<string>() { "None", "1", "2" }; return list; } set { } } I get an object not set to instance of object error though. Ideas?

  • Display a ranking grid for game : optimization of left outer join and find a player

    - by Jerome C.
    Hello, I want to do a ranking grid. I have a table with different values indexed by a key: Table SimpleValue : key varchar, value int, playerId int I have a player which have several SimpleValue. Table Player: id int, nickname varchar Now imagine these records: SimpleValue: Key value playerId for 1 1 int 2 1 agi 2 1 lvl 5 1 for 6 2 int 3 2 agi 1 2 lvl 4 2 Player: id nickname 1 Bob 2 John I want to display a rank of these players on various SimpleValue. Something like: nickname for lvl Bob 1 5 John 6 4 For the moment I generate an sql query based on which SimpleValue key you want to display and on which SimpleValue key you want to order players. eg: I want to display 'lvl' and 'for' of each player and order them on the 'lvl' The generated query is: SELECT p.nickname as nickname, v1.value as lvl, v2.value as for FROM Player p LEFT OUTER JOIN SimpleValue v1 ON p.id=v1.playerId and v1.key = 'lvl' LEFT OUTER JOIN SimpleValue v2 ON p.id=v2.playerId and v2.key = 'for' ORDER BY v1.value This query runs perfectly. BUT if I want to display 10 different values, it generates 10 'left outer join'. Is there a way to simplify this query ? I've got a second question: Is there a way to display a portion of this ranking. Imagine I've 1000 players and I want to display TOP 10, I use the LIMIT keyword. Now I want to display the rank of the player Bob which is 326/1000 and I want to display 5 rank player above and below (so from 321 to 331 position). How can I achieve it ? thanks.

  • Find the Algorithm that generates the checksum

    - by knivmannen
    I have a sensing device that transmits a 6-byte message along with an 1-byte counter and supposely a checksum. The data looks something like this: ------DATA----------- -Counter- --Checksum?-- 55 FF 00 00 EC FF ---- 60---------- 1F The last four bits in the counter are always set 0, i.e those bits are probably not used. The last byte is assumed to be the checksum since it has a quite peculiar nature. It tends to randomly change as data changes. Now what i need is to find the algorithm to compute this checksum based on --DATA--. what i have tried is all possible CRC-8 polynomials, for each polynomial i have tried to reflect data, toggle it, initiate it with non-zeroes etc etc. Ive come to the conclusion that i am not dealing with a normal crc-algorithm. I have also tried some flether and adler methods without succes, xor stuff back and forth but still i have no clue how to generate the checksum. My biggest concern is, how is the counter used??? Same data but with different countervalue generates different checksums. I have tried to include the counter in my computations but without any luck. Here are some other datasamples: 55 FF 00 00 F0 FF A0 38 66 0B EA FF BF FF C0 CA 5E 18 EA FF B7 FF 60 BD F6 30 16 00 FC FE 10 81 One more thing that might be worth mentioning is that the last byte in the data only takes on the values FF or FE Plz if u have any tips or tricks that i may try post them here, I am truly desperate. Thx

  • Using a string inside the DocumentBuilder parse method (need it for parsing XML using XPath)

    - by dierre
    Hi guys! I'm trying to create a RESTful webservice using a Java Servlet. The problem is I have to pass via POST method to a webserver a request. The content of this request is not a parameter but the body itself. So I basically send from ruby something like this: url = URI.parse(@host) req = Net::HTTP::Post.new('/WebService/WebServiceServlet') req['Content-Type'] = "text/xml" # req.basic_auth 'account', 'password' req.body = data response = Net::HTTP.start(url.host, url.port){ |http| puts http.request(req).body } Then I have to retrieve the body of this request in my servlet. I use the classic readline, so I have a string. The problem is when I have to parse it as XML: private void useXML( final String soft, final PrintWriter out) throws ParserConfigurationException, SAXException, IOException, XPathExpressionException, FileNotFoundException { DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance(); domFactory.setNamespaceAware(true); // never forget this! DocumentBuilder builder = domFactory.newDocumentBuilder(); Document doc = builder.parse(soft); XPathFactory factory = XPathFactory.newInstance(); XPath xpath = factory.newXPath(); XPathExpression expr = xpath.compile("//software/text()"); Object result = expr.evaluate(doc, XPathConstants.NODESET); NodeList nodes = (NodeList) result; for (int i = 0; i < nodes.getLength(); i++) { out.println(nodes.item(i).getNodeValue()); } } The problem is that builder.parse() accepts: parse(File f), parse(InputSource is), parse(InputStream is). Is there any way I can transform my xml string in an InputSource or something like that? I know it could be a dummy question but Java is not my thing, I'm forced to use it and I'm not very skilled.

  • Project management: Implementing custom errors in VS compilation process

    - by David Lively
    Like many architects, I've developed coding standards through years of experience to which I expect my developers to adhere. This is especially a problem with the crowd that believes that three or four years of experience makes you a senior-level developer.Approaching this as a training and code review issue has generated limited success. So, I was thinking that it would be great to be able to add custom compile-time errors to the build process to more strictly enforce this and other guidelines. For instance, we use stored procedures for ALL database access, which provides procedure-level security, db encapsulation (table structure is hidden from the app), and other benefits. (Note: I am not interested in starting a debate about this.) Some developers prefer inline SQL or parametrized queries, and that's fine - on their own time and own projects. I'd like a way to add a compilation check that finds, say, anything that looks like string sql = "insert into some_table (col1,col2) values (@col1, @col2);" and generates an error or, in certain circumstances, a warning, with a message like Inline SQL and parametrized queries are not permitted. Or, if they use the var keyword var x = new MyClass(); Variable definitions must be explicitly typed. Do Visual Studio and MSBuild provide a way to add this functionality? I'm thinking that I could use a regular expression to find unacceptable code and generate the correct error, but I'm not sure what, from a performance standpoint, is the best way to to integrate this into the build process. We could add a pre- or post-build step to run a custom EXE, but how can I return line- and file-specifc errors? Also, I'd like this to run after compilation of each file, rather than post-link. Is a regex the best way to perform this type of pattern matching, or should I go crazy and run the code through a C# parser, which would allow node-level validation via the parse tree? I'd appreciate suggestions and tales of prior experience.

  • javax.xml.ws.soap.SOAPFaultException: Could not send Message - at JaxWsClientProxy.invoke - caused by HTTP response code: 401 for URL

    - by Mikkis
    I moved a working code from dev to test and encountered the following error(s) in test: javax.xml.ws.soap.SOAPFaultException: Could not send Message. at org.apache.cxf.jaxws.JaxWsClientProxy.invoke(JaxWsClientProxy.java:143) ...... at org.apache.cxf.interceptor.MessageSenderInterceptor$MessageSenderEndingInterceptor.handleMessage(MessageSenderInterceptor.java:64) at org.apache.cxf.phase.PhaseInterceptorChain.doIntercept(PhaseInterceptorChain.java:236) at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:472) at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:302) at org.apache.cxf.endpoint.ClientImpl.invoke(ClientImpl.java:254) at org.apache.cxf.frontend.ClientProxy.invokeSync(ClientProxy.java:73) at org.apache.cxf.jaxws.JaxWsClientProxy.invoke(JaxWsClientProxy.java:123) at $Proxy739.copyIntoItems(Unknown Source) Caused by: java.io.IOException: Server returned HTTP response code: 401 for URL: http:///_vti_bin/Copy.asmx at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1436) at java.net.HttpURLConnection.getResponseCode(HttpURLConnection.java:379) at org.apache.cxf.transport.http.HTTPConduit$WrappedOutputStream.handleResponseInternal(HTTPConduit.java:2046) Environment specs: Java 1.6 Tomcat 6 Eclipse Helios Maven2 CXF 2.2.3 As a background work, tried to explore about the error in similar category bad URL (ruled out as i am using same URL in dev and test. and the url, userid, password are all accessible from both the machines), connection timeout( error is not 404 or it doesnt specify connection timed out... it says 401 response code for url) Checked if all the jars and same versions are included in the test environment. Can someone shed some light to understand and resolve the error? please let me know if any more details are to be included.

  • What's with bad function call in view generated via scaffold?

    - by meta
    I've scaffolded Things element: script/generate scaffold wip/thing name:string and got some invalid function call in views, like: <td><%= link_to 'Edit', edit_thing_path(thing) %></td> Which raise this error: ActionView::TemplateError (undefined method `edit_thing_path' for #<ActionView::Base:0xb5c00944>) on line #11 of app/views/wip/things/index.html.erb: 8: <tr> 9: <td><%=h thing.name %></td> 10: <td><%= link_to 'Show', thing %></td> 11: <td><%= link_to 'Edit', edit_thing_path(thing) %></td> 12: <td><%= link_to 'Destroy', thing, :confirm => 'Are you sure?', :method => :delete %></td> 13: </tr> 14: <% end %> What's with that function? Where is it? Is it some kind of automagic stuff or do I need to implement it (if so - where should it go?) I have resource defined in routes with namespace: map.namespace :wip do |wip| wip.resources :things end rake routes gives me this: wip_things GET /wip/things(.:format) {:action=>"index", :controller=>"wip/things"} POST /wip/things(.:format) {:action=>"create", :controller=>"wip/things"} new_wip_thing GET /wip/things/new(.:format) {:action=>"new", :controller=>"wip/things"} edit_wip_thing GET /wip/things/:id/edit(.:format) {:action=>"edit", :controller=>"wip/things"} wip_thing GET /wip/things/:id(.:format) I assumed that those names (wip_thing, new_wip_thing) are the correct names, but it's still gives me that error Thanks.

  • 3D Sphereical Terrain with an 8 mesh sphere. The edges of the mesh are obvioulsy seen and I'm not su

    - by Justin808
    Hi :) I'm working in Unity3D, but my issue is with 3D meshes. I'm hoping someone here can help or point me in the right direction. I have 2 version of code, http://www.pasteit4me.com/695002 (old) and http://www.pasteit4me.com/690003 (new). The old code, makes a single mesh sphere and creates a terrain on it. The new code makes an 8 mesh sphere and creates a terrain on it. On the new version the edges of the meshes are obviously seen and I'm not sure why. It looks like the edges are adjusted no much, almost 2-3 times more than they should have been. GenerateB() in the old code and Generate() in the new code creates the sphere. MakeTerrain() in both create the terrain. If I dont run the MakeTerrain() function the new sphere looks like a solid mesh. I'm not sure where to start looking in the MakeTerrain() function in the new code to solve the issue :-/ Any ideas? An image of the issue is at http://img28.imageshack.us/img28/3784/screenshot20100611at850.png.

  • 2D Histogram in R: Converting from Count to Frequency within a Column

    - by Jac
    Would appreciate help with generating a 2D histogram of frequencies, where frequencies are calculated within a column. My main issue: converting from counts to column based frequency. Here's my starting code: # expected packages library(ggplot2) library(plyr) # generate example data corresponding to expected data input x_data = sample(101:200,10000, replace = TRUE) y_data = sample(1:100,10000, replace = TRUE) my_set = data.frame(x_data,y_data) # define x and y interval cut points x_seq = seq(100,200,10) y_seq = seq(0,100,10) # label samples as belonging within x and y intervals my_set$x_interval = cut(my_set$x_data,x_seq) my_set$y_interval = cut(my_set$y_data,y_seq) # determine count for each x,y block xy_df = ddply(my_set, c("x_interval","y_interval"),"nrow") # still need to convert for use with dplyr # convert from count to frequency based on formula: freq = count/sum(count in given x interval) ################ TRYING TO FIGURE OUT ################# # plot results fig_count <- ggplot(xy_df, aes(x = x_interval, y = y_interval)) + geom_tile(aes(fill = nrow)) # count fig_freq <- ggplot(xy_df, aes(x = x_interval, y = y_interval)) + geom_tile(aes(fill = freq)) # frequency I would appreciate any help in how to calculate the frequency within a column. Thanks! jac EDIT: I think the solution will require the following steps 1) Calculate and store overall counts for each x-interval factor 2) Divide the individual bin count by its corresponding x-interval factor count to obtain frequency. Not sure how to carry this out though. .

  • Ruby on Rails Mongrel web server stuck when MySQL service is running

    - by Marcos Buarque
    Hi, I am a Ruby on Rails newbie and already have a problem. I have started the Mongrel web server and it works fine when MySQL service isn't running. But when MySQL is on, Mongrel stucks. It ceases from serving the pages. So far, I have tested the localhost:3000 URL. When MySQL is off, it serves the page. When I click "about application's environment", I get the messasge (of course) "Can't connect to MySQL server on 'localhost' (10061)". After starting the MySQL service and refreshing, I get no more answer and Mongrel does not serve the webpage. It gets stuck with no answer to the browser. Then I have to stop the webserver and restart it. I have installed mysql2 gem with the command gem install mysql2. I was able to create the _test and _development databases with the command line rake db:create. I have tested with MySQL root user and blank password and also tried with a superuser user I have created. No success. Here is the server log: ======================== Started GET "/rails/info/properties" for 127.0.0.1 at Fri Dec 24 17:41:25 -0200 2010 Mysql2::Error (Can't connect to MySQL server on 'localhost' (10061)): Rendered C:/Ruby187/lib/ruby/gems/1.8/gems/actionpack-3.0.3/lib/action_dispatch/middleware/templates/rescues/_trace.erb (1.0ms) Rendered C:/Ruby187/lib/ruby/gems/1.8/gems/actionpack-3.0.3/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (5.0ms) Rendered C:/Ruby187/lib/ruby/gems/1.8/gems/actionpack-3.0.3/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (35.0ms) ================= I am running on a Windows 7 environment with firewall down.
