  • IP packet proxy solutions? Riverbed alternative

    - by Ruvan
    I have stumbled upon Riverbed.com's products which basically has the capability to hash chunks of IP data and subsequently store them to disk. I'm looking for an open source / cheaper alternative. WANProxy is the exact equivalent except that it only keeps data in-memory and can't store the data to disk which is a requirement for our solution. I'm basically looking for a proxy which not only looks at the files (filenames) but the data itself being transmitted at the packet level. Anyone? Thanks!

  • Deploy to web container, bundle web container or embed web container...

    - by Jason
    I am developing an application that needs to be as simple as possible to install for the end user. While the end users will likely be experience Linux users (or sales engineers), they don't really know anything about Tomcat, Jetty, etc, nor do I think they should. So I see 3 ways to deploy our applications. I should also state that this is the first app that I have had to deploy that had a web interface, so I haven't really faced this question before. First is to deploy the application into an existing web container. Since we only deploy to Suse or RedHat this seems easy enough to do. However, we're not big on the idea of multiple apps running in one web container. It makes it harder to take down just one app. The next option is to just bundle Tomcat or Jetty and have the startup/shutdown scripts launch our bundled web container. Or 3rd, embed.. This will probably provide the same user experience as the second option. I'm curious what others do when faced with this problem to make it as fool proof as possible on the end user. I've almost ruled out deploying into an existing web container as we often like to set per application resource limits and CPU affinity, which I believe would affect all apps deployed into a web container/app server and not just a specific application. Thank you.

  • Weird exception in linkbutton in a datalist

    - by user308806
    Dear all, I have written this datalist : <div class="story" runat="server"> <asp:DataList ID="DataList2" runat="server" Height="16px" Width="412px"> <SeparatorTemplate> <hr /> </SeparatorTemplate> <ItemTemplate> <asp:LinkButton ID="LinkButton1" runat ="server" Text='<%# Eval("Name") %>' PostBackUrl='<%#Eval("Url")%>' /> <br /> Description: <asp:Label ID="new" Text='<%#Eval("Description") %>' runat="server" /> </ItemTemplate> </asp:DataList> </div> It raises an exception saying that the linkbutton has to be placed in a tag that contains runat="server" although it exists.

  • Delphi native Web Service applications not working. IIS 7 seems to be stripping the pathinfo

    - by Cary Jensen
    I've run into an interesting problem that I never encountered with XP or IIS 6. Basically, I can't get a native Delphi (WebBroker) Web service server to work with a native Web service client in Windows 7 64-bit. Here's the most basic breakdown. If I create a new Web service application in Delphi 2010 (or any version, back to Delphi 7), and access it using IE 8, I can see the HTML that the WSDLHTMLPublish component creates, but I can never get to the SOAP. In the same way, the WSDL Importer cannot get to the SOAP either. (I have IIS 7 configured to use a 32-bit application pool, and I have created a working Script Map to the Handler Mappings. In short, the 32-bit ISAPI Web service is running). For example, I have a simple Web service server named TestService (created using the default sample interface generated when you create a new Web service server). I installed it in a virtual directory named scripts. If I enter http://localhost/scripts/TestService.dll/wsdl, IIS 7 displays the page http://localhost/scripts/TestService.dll. If I put my mouse over the WSDL link for the ITestService, I see http://localhost/scripts/TestService.dll/wsdl/ITestService in the status bar. However, when I click this link, the address bar shows http://localhost/scripts/TestService.dll/wsdl/ITestService, but I see only the HTML from http://localhost/scripts/TestService.dll. There seems no way to get to the SOAP definition. IIS 7 seems to be ignoring everything after the script name (it is ignoring the pathinfo). Additional evidence that IIS7 is stripping off the pathinfo is that if I pause my mouse over the ITestService link, the statusbar shows http://localhost/scripts/TestService.dll?intf=ITestService. Clicking that link takes me to another HTML page, the one associated with http://localhost/scripts/TestService.dll?intf=ITestService. However, any link that includes a pathinfo following the script name, takes me simply to http://localhost/scripts/TestService.dll. I have tested this in Delphi 7, Delphi 2010, and Delphi XE, with the same results. I am guessing that IIS7 is stripping off the pathinfo, since even the WSDL Importer cannot get to the SOAP definition. Tried creating a new Web service using the CGI option, and got the same result. Have any idea what is going on? Added: Bob Swart reports he has had no problems under Windows 7 32-bit. Downloading the 32-bit OS and will try that (in a new VM).

  • Consuming Web Services requiring Authentication from behind Proxy server

    - by Jan Petersen
    Hi All, I've seen a number of post about Proxy Authentication, but none that seams to address this problem. I'm building a SharePoint Web Service consuming desktop application, using Java, JAX-WS in NetBeans. I have a working prototype, that can query the server for authentication mode, successfully authenticate and retrieve a list of web site. However, if I run the same app from a network that is behind a proxy server (the proxy does not require authentication), then I'm running into trouble. The normal -dhttp.proxyHost ... settings does not seam to help any. But I have found that by creating a ProxySelector class and setting it as default, I can regain access to the authentication web service, but I still can't retrieve the list of web sites from the SharePoint server. It's almost as if the authentication I provide is going to the proxy rather than the SharePoint server. Anyone have any experience on how to make this work? I have put the source text java class files of a demo app up, showing the issue at the following urls (it's a bit to long even in the short demo form to post here). link text When running the code from a network behind a proxy server, I successfully retrieve the Authentication mode from the server, but the request for the Web Site list generates an exception originating at: com.sun.xml.internal.ws.transport.http.client .HttpClientTransport.readResponseCodeAndMessage(HttpClientTransport.java:201) The output from the source when no proxy is on the network is listed below: Successfully retrieved the SharePoint WebService response for Authentication SharePoint authentication method is: WINDOWS Calling Web Service to retrieve list of web site.

  • boost::spirit::karma using the alternatives operator (|) with conditions

    - by Ingemar
    I'm trying to generate a string from my own class called Value using boost::spirit::karma, but i got stuck with this. I've tried to extract my problem into a simple example. I want to generate a String with karma from instances of the following class: class Value { public: enum ValueType { BoolType, NumericType }; Value(bool b) : type_(BoolType), value_(b) {} Value(const double d) : type_(NumericType), value_(d) {}; ValueType type() { return type_; } operator bool() { return boost::get<bool>(value_); } operator double() { return boost::get<double>(value_); } private: ValueType type_; boost::variant<bool, double> value_; }; Here you can see what I'm tying to do: int main() { using karma::bool_; using karma::double_; using karma::rule; using karma::eps; std::string generated; std::back_insert_iterator<std::string> sink(generated); rule<std::back_insert_iterator<std::string>, Value()> value_rule = bool_ | double_; Value bool_value = Value(true); Value double_value = Value(5.0); karma::generate(sink, value_rule, bool_value); std::cout << generated << "\n"; generated.clear(); karma::generate(sink, value_rule, double_value); std::cout << generated << "\n"; return 0; } The first call to karma::generate() works fine because the value is a bool and the first generator in my rule also "consumes" a bool. But the second karma::generate() fails with boost::bad_get because karma tries to eat a bool and calls therefore Value::operator bool(). My next thought was to modify my generator rule and use the eps() generator together with a condition but here i got stuck: value_rule = (eps( ... ) << bool_) | (eps( ... ) << double_); I'm unable to fill the brackets of the eps generator with sth. like this (of course not working): eps(value.type() == BoolType) I've tried to get into boost::phoenix, but my brain seems not to be ready for things like this. Please help me! here is my full example (compiling but not working): main.cpp

  • Project Reference added to one of the projects in the same solution appears broken in another solution

    - by CSharpLearner
    I have couple of solutions. In the first solution I have many projects. One of the project named 'A' has a project reference of another project 'B' of the same solution. In second solution, the project 'A' is added but not the project 'B'. Both the solutions build successfully. However, in second solution, reference of B added in the project A, appears broken. Why? Now, in first solution, instead of adding Project reference of B into A, i simply add a 'file reference' of B's DLL (which is copied at the common output directory created for all the projects) into A. Now the reference appears broken in both the solution even though both the solutions are built successfully. May I know what should I do when I have such a scenario?

  • Are the old httpHandlers and httpModules elements needed in IIS7?

    - by James Newton-King
    I'd like to clean up the web.config and remove unneeded XML. A default ASP.NET 3.5 web application has the follow elements in the web.config: <httpHandlers> <remove verb="*" path="*.asmx"/> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false"/> </httpHandlers> <httpModules> <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web.Routing, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </httpModules> When running under IIS7, which has modules and handlers being registered under the system.webServer element, is the configuration above still needed?

  • Eclipse / Aptana File Sync Solutions

    - by Brad
    Our development team uses Eclipse + Aptana to do their web development work. Currently, most of them are mapping their Eclipse projects directly to the web server. I'd rather them create a local project and use that to sync to the web server project directory they are working on. The issue is that there aren't any good solutions which is just appalling given the popularity of the two. The FileSync plugin for Eclipse is only one-way. Meaning if another developer makes a change to the file on the server, another dev isn't even notified and could overwrite the change. The File Transfer option in Aptana 2.0 doesn't support any sort of Sync, just manually uploading/downloading files. The Sync option in Aptana 1.5.1 doesn't allow you to merge files when they are different. You can only update one or the other. It does however allow you to view a diff (but only if you right click and select) and in that diff you can't make any changes. I did find a way to allow files to be uploaded to their Sync repositories in Aptana using Eclipse Monkey. However it doesn't work if a user saves multiple files at once, 'Save All', again it doesn't work. And additionally, there is no notification if a user opens a local file that has an updated copy on the server. I tried to add one using Eclipse Monkey but I couldn't find any sort of listener in the Eclipse API to do it and any Eclipse Monkey documentation is far and few between. My only solution at this point is just to let them continue to map directly to the server or ask them to do a manual download before they do any work (but again what if someone uploads a change right after they do that). Anyone have any ideas?

  • Awk filtering values between two files when regions intersect (any solutions welcome)

    - by user964689
    This is building upon an earlier question Awk conditional filter one file based on another (or other solutions) I have an awk program that outputs a column from rows in a text file 'refGene.txt if values in that row match 2 out of 3 values in another text file. I need to include an additional criteria for finding a match between the two files. The criteria is inclusion if the range of the 2 numberical values specified in each row in file 1 overlap with the range of the two values in a row in refGene.txt. An example of a line in File 1: chr1 10 20 chr2 10 20 and an example line in file 2(refGene.txt) of the matching columns ($3, $5, $ 6): chr1 5 30 Currently the awk program does not treat this as a match because although the first column matches neither the 2nd or 3rd columns do no. But I would like a way to treat this as a match because the region 10-20 in file 1 is WITHIN the range of 5-30 in refGene.txt. However the second line in file 1 should NOT match because the first column does not match, which is necessary. If there is a way to include cases when any of the range in file 1 overlaps with any of the range in refGene.txt that would be really helpful. It should also replace the below conditional statements as it would also find all the cases currently described below. Please let me know if my question is unclear. Any help is really appreciated, thanks it advance! (solutions do not have to be in awk) Rubal FILES=/files/*txt for f in $FILES ; do awk ' BEGIN { FS = "\t"; } FILENAME == ARGV[1] { pair[ $1, $2, $3 ] = 1; next; } { if ( pair[ $3, $5, $6 ] == 1 ) { print $13; } } ' $(basename $f) /files/refGene.txt > /files/results/$(basename $f) ; done
