  • How do I trust a self signed cert using https?

    - by dave
    Edit: I originally thought the server's certificate was self signed. Turns out it was signed by a self-signed CA certificate. I'm trying to write a Node.js application that accesses an HTTPS site that's protected using a self-signed certificate certificate signed by a private, self-signed CA certificate. I'd also like to not completely disable certificate checking. I tried putting the self signed certificate server's certificate in the request options, but that doesn't seem to be working. Anyone know how to do this? I expect the following code to print statusCode 200, but instead it prints [Error: SELF_SIGNED_CERT_IN_CHAIN]. I've tried similar code with request with the same results. var https = require('https'); var fs = require('fs'); var opts = { hostname: host, port: 443, path: '/', method: 'GET', ca: fs.readFileSync(serverCertificateFile, 'utf-8') }; var req = https.request(opts, function (res) { console.log('statusCode', res.statusCode); }); req.end(); req.on('error', function (err) { console.error(err); });

  • Translate Basic Config.groovy log4j DSL to external log4j.properties

    - by Stephen Swensen
    The following is a basic log4j configuration inside Config.groovy using the log4j DSL with Grails 1.2, it works as expected (log all errors to the given file): log4j = { appenders { file name:'file', file:"c:/error.log" } error 'grails.app' root { error 'file' } } How would one translate this into a properties style log4j configuration file? The following does not work: log4j.rootLogger=ERROR, FA log4j.appender.FA=org.apache.log4j.FileAppender log4j.appender.FA.File=C:/error.log log4j.logger.grails.app=ERROR, FA I suspect it has something to do with the translation of error 'grails.app' but I really don't know. If it makes any difference, the properties file is configured externally: grails.config.locations = ["file:${basedir}/extconf/log4j.properties"] All I really want is an external log4j properties file which logs all application exceptions to a file.

  • Unable to set cookie in response header (newcookie doesn't show in external browser) : Jersey jax-rs

    - by Pankhuri
    I am trying to set a session cookie from server side : import javax.ws.rs.core.NewCookie; import javax.ws.rs.core.Response; public class Login { @POST @Produces("application/json") @Consumes("application/json") public Response login (String RequestPacket){ NewCookie cookie=null; CacheControl cc=new CacheControl(); cookie = LoginBO.validUser(RequestPacket); cc.setNoCache(true); if(cookie.getValue()!=null) return Response.ok("welcome "+cookie.getValue()).cookie(cookie).cacheControl(cc).build(); else return Response.status(404).entity("Invalid User").build(); } } In eclipse browser: on the client side (using gxt for that) when I print header i get the Set-Cookie field. which is expected. But the browser is not storing the cookie. in external browser: the header doesn't have any set-cookie field. Should I use HTTPServletResponse? But shouldn't the javax.ws.rs.core.Response work as well?

  • Python Tkinter - Edit external object within event handler?

    - by M3RPHY
    Hey all, As the title says, I'm grabbing the cursor location within a motion triggered event handler in Tkinter. I'd like to update an existing label widget with the location, however I cannot for the life of me figure out how to edit the label's text field (or any external object for that matter) within the event handler. From what I understand, event is the only argument passed to the handler, which means I can't pass the label object. How do I access objects outside of the handler? Apologize for the noobish question as I'm a C programmer new to Python. Thanks!

  • Should External Routine Be Declared Always in Fortran?

    - by Ngu Soon Hui
    In my fortran code I made the following call to dnrm2 routine d = dnrm2(n, ax, 1) Just a simple call that would return me a double precision result. The problem is whether I should declare the function at the start of my script. I found that if I don't declare it, and when I compile the code in 32 bit Windows, then the result is correct. But if I compile the code in 64 bit Windows, then the result won't be correct. Why this is so? Is external routine must always be declared?

  • Why Won't the WebSocket.onmessage Event Fire?

    - by SumWon
    Hey guys, After toying around with this for hours, I simply cannot find a solution. I'm working on a WebSocket server using "node.js" for a canvas based online game I'm developing. My game can connect to the server just fine, it accepts the handshake and can even send messages to the server. However, when the server responds to the client, the client doesn't get the message. No errors, nothing, it just sits there peacefully. I've ripped apart my code, trying everything I could think of to fix this, but alas, nothing. Here's a stripped copy of my server code. As I said before, the handshake works fine, the server receives data fine, but sending data back to the client does not. var sys = require('sys'), net = require('net'); var server = net.createServer(function (stream) { stream.setEncoding('utf8'); var shaken = 0; stream.addListener('connect', function () { sys.puts("New connection from: "+stream.remoteAddress); }); stream.addListener('data', function (data) { if (!shaken) { sys.puts("Handshaking..."); //Send handshake: stream.write( "HTTP/1.1 101 Web Socket Protocol Handshake\r\n"+ "Upgrade: WebSocket\r\n"+ "Connection: Upgrade\r\n"+ "WebSocket-Origin: http://192.168.1.113\r\n"+ "WebSocket-Location: ws://192.168.1.71:7070/\r\n\r\n"); shaken=1; sys.puts("Handshaking complete."); } else { //Message received, respond with 'testMessage' var d = "testMessage"; var m = '\u0000' + d + '\uffff'; sys.puts("Sending '"+m+"' to client"); var result = stream.write(m, "utf8"); sys.puts(result); /* Result comes as true, meaning that it pushed the data out. Why isn't the client seeing it?!? */ } }); stream.addListener('end', function () { sys.puts("Connection closed!"); stream.end(); }); }); server.listen(7070); sys.puts("Server Started!");

  • External Reference to Richfaces modal

    - by John
    Hi, I need to get a <rich:modalPanel id="mod1" .../> component to load an external page on "show" action, defined as: <a4j:commandButton value="link" id="l1" reRender="mod1" oncomplete="Richfaces.showModalPanel('mod1')"> <f:setPropertyActionListener target="#{mybean.someParam}" value="#{myOtherbean.someOtherparam}" /> </a4j:commandButton> . My first try was with <rich:modalPanel id="mod1"> <ui:include src="#{mybean.generateURL()"/> </rich:modalPanel> but it just throws me a 404 page not found error, typing the generated URL directly into the address bar works perfectly fine. Does anyone know what's causing the problem , or what's the correct way to do this? The system is running on seam/richfaces. Thanks!

  • Subsume external library into source tree with Autotools.

    - by troutwine
    I am developing a new project, using Autotools for my build infrastructure. I would like to subsume external dependencies into my source tree. These dependencies are using Autotools, as well. How can I configure my project's build scripts to build and link against subsumed dependencies? Though Duret-Lutz's tutorial is excellent, this situation is only briefly addressed in a few slides. I found his explanation deeply confusing. By adding the directory name of subsumed dependencies to the toplevel Makefile.am's SUBDIRS the dependency is being configured and built. It is possible to manually set include paths through CFLAGS, but how do I link against libtool .la files?

  • Execution of "mvn sonar:sonar" with no external access

    - by romaintaz
    Hello, I try to execute the mvn sonar:sonar command on a machine where Maven is configured to have no access to external repositories (in reality, this is not exactly the case, but it helps me to explain my problem). So currently, if I run this command, I get the following error: [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] The plugin 'org.codehaus.mojo:sonar-maven-plugin' does not exist or no valid version could be found I think it means that I have some incorrect metadata in my local repository, as I have a [local repo]\org\codehaus\mojo\sonar-maven-plugin\1.0-beta-1 directory (with the JAR inside, of course). Have you any idea why my command is failing? tech infos: Maven 2.2.1, Java 1.6, Sonar 2.1.2

  • Best practices for TDD BDD with code that uses external services / api

    - by adam
    I'm using a twitter gem which basically accesses twitter and lets me grab tweets, timeline etc. Its really good but I have a lot of my code that uses the stuff it returns and I need to test it. The things the gem returns aren't exactly simple strings, there pretty complex objects (scary as well) so im left scratching my head. So basically I'm looking for an answer, book, blog, open-source project that can show me the rights and wrongs of testing around external services. answers that are either not language centric or ruby/rails centric would most greatly be appreciated.

  • How to prevent a globally overridden "new" operator from being linked in from external library

    - by mprudhom
    In our iPhone XCode 3.2.1 project, we're linking in 2 external static C++ libraries, libBlue.a and libGreen.a. libBlue.a globally overrides the "new" operator for it's own memory management. However, when we build our project, libGreen.a winds up using libBlue's new operator, which results in a crash (presumably because libBlue.a is making assumptions about the kinds of structures being allocated). Both libBlue.a and libGreen.a are provided by 3rd parties, so we can't change any of their source code or build options. When we remove libBlue.a from the project, libGreen.a doesn't have any issues. However, no amount of shuffling the linking order of the libraries seems to fix the problem, nor does any experimentation with the various linking flags. Is there some way to tell XCode to tell the linker to "have libGreen's use of the new operator use the standard C++ new operator rather than the one redefined by libBlue"?

  • Setting the colour scheme for a Silverlight app from an external resource

    - by Alex Angas
    I have a Silverlight 3 application containing six custom user controls. I'd like to load the colour scheme for these controls from an external resource. The code and XAML containing a default colour scheme would be built in the XAP. Then a parameter on the object tag would contain a URL from where alternate colours can be dynamically loaded. By the way, the Silverlight 3 application theme feature could be used if that's possible but is really overkill. Only colours need to be changed. Is this possible and how would you recommend to do it?

    - by Nikunj Chauhan
    I have a Java project in Eclipse with class MainClass having main method in package : com.nik.mypackage. The project also references two external libraries, which I copied in the lib folder in Eclipse and then added to build path using ADD JAR function. The libraries being one.jar and two.jar This library is in lib folder in eclipse and added to the build path. I want to create a executable JAR of the application using ant script. So that user can access my application using command: c:>java -jar MyProject-20111126.jar I know about the Eclipse plugin which directly exports a java application as runnable JAR. But I want to learn ant and the build process so manually want to create the build.xm.

  • Mac dashboard widgets not loading external images

    - by andrhamm
    I set out to make a quick Mac OS X dashboard widget. I read the documentation and was pleased to find out they use simple HTML, JS, and CSS. I created my widget and it works when I open the .html file in Firefox, but it does not work when I install the widget to the dashboard. The widget is simple: it displays the most recent image from a weather web cam stream. The image URLs look like this: http://webcam.com/stream.jpg?1274213999617. The timestamp is appended to the URL and the server automatically responds with the latest image for that time. I did not write the server script. The widget appears to be loading correctly, but the web cam image will not load. Notice the blue question mark in the upper left. The image should appear over the square background image. Is there any special procedure for loading external images into a widget?

  • include external jar when running java -jar

    - by prmatta
    From my readings, when you execute a command as follows: java -jar foo.jar Then the main classpath is ignored and the classpath is taken from the manifest file. Further, the classpath declared on the command line is also ignored. So in: java -classpath /usr/local/jar/foobar.jar -jar foo.jar /usr/local/jar/foobar.jar is ignored. Lastly, I have read that the manifest file can only only contain relative paths, within the jar file. So, how do you include absolute paths to external jars, that are present on the system, but not in the jar file being executed?

  • Javascript Close Browser or goto external site function

So far I've come up with this, any help is greatly appreciated. <script type="text/javascript"> window.onbeforeunload = confirmExit; function getAd() { var myAds = new Array(); myAds[0] = "http://localhost/link1"; myAds[1] = "http://localhost/link2"; var randomAd = Math.floor(Math.random() * myAds.length); return myAds[randomAd]; } function confirmExit(){ alert(getAd()); return false; } </script>

  • Open a PDF file in an external app on iPad

    - by Yuji
    I'd like to make my app to open a specified PDF by an external app of the user's choice on the iPad. How can I do that? Or, is there any open-source PDF reader framework available so that I can put it into my app? My situation in more detail: I'm thinking of porting to the iPad from OS X / rewriting from scratch for the iPad an app which manages lots of PDFs (journal articles, etc.), but I don't want to write the PDF reader part, because there are many good ones already out there; I don't want to reinvent the wheels. (You might say you shouldn't reinvent pdf management apps, but I'd like to make one as a front end to SPIRES, and there isn't one so far.) As the app would be a front end to a serious reading activity, UIWebView's pdf capability is not enough. Also, users of my app would have various preferences which app to use. That's the background behind my question. Thanks in advance!

  • External Javascript Timeout

    - by yummm
    I have a number of tracking scripts and web services installed on my website and I noticed when one of the services goes down, it still tries to call the external javascript file hosted on a different server. In Firefox, Chrome and other new browsers, there doesn't seem to be any issues when one of the services go down. However, in IE7 and IE8, my pages don't load all the way and time out before everything is displayed. Is there any way to add a time out on these javascript calls to prevent them from breaking my pages when they go down?
