  java javassist
  With Javassist, is there any way to inject code into a native method? In this case, I’m trying to make the OpenGL calls in my game print out their names and values when called, but all my attempts have hit errors when I assume the openGL dll code is added.The method would look something like:public static native void glEnable(int paramInt);Since the methods initially have no body, the only way I’ve found to actually add the code is with something like:CtBehavior method = cl.getDeclaredBehaviors(

  java eclipse leap-motion
  I have a project that uses leap motion sdk. I wrote this project in Eclipse. When I run my program I don’t have any problem because I set my native libraries as it is suggested from configuration. However, when I export my application I can not run my program because Eclipse does not include my native libraries and I am having this error.

  java android upnp
  From Android 4.1 (under Wi-Fi Direct service discovery) it is suppose to support native UPnP service discovery.I presume it was developed for Wi-Fi Direct, but the methods available seem to be generic. Even the JavaDoc for methods mention that it searches for all UPnP services on the network and not only WiFi Direct slaves/masters.However, I am failing to implement it so that it works… I manage to set up all requirements and I get positive onSuccess callbacks, but I receive no onUpnpServiceAva

  java dll linker jni
  I’ve got a bit of an odd problem. I have a project in C++ that’s basically a wrapper for a third party DLL like this:MyLibrary –loads DLL_A —-loads DLL_BI load DLL_A with LoadLibrary(), wrap several of its functions and generate my own DLL. I’ve tested this in a C++ project and a C# project. Both do everything they’re supposed to do: load DLL_A, make a couple of function calls, and indirectly load DLL_B. The problem is when I build a DLL for java and make the calls through JNI. Everything run

  java java-web-start java-native-interface
  I am using Java Web Start to launch a Java application that depends on some third party native libraries. These native libraries then subsequently load another native library (commonLib) as their dependency using LoadLibrary/dlopen.When not using Web Start, everything works as expected when the native libraries are located in the same directory.Web Start, however, requires the native libraries to be packed in a jar file and referenced in the jnlp file, which I did:<!– Windows OS –><re

  I am having issues while running job with large data (~15G) on hadoop cluster using SimString Native library. However job runs fine on medium/small dataset(~200M).

  I have been on this for a couple of days, no solution. I pray somebody gives an adequate answer to get this resolved. It’ll really be an accomplishment. What I want to achieve There are only three (3) controls on the interface – a dropdown, an input, and a submit button. The dropdown gets its values from a column (ownerName) in a table in the database. To perform a transaction from the interface, a value is selected from the dropdown, a value is inputted into the input box (textbox) which is t

  javascript ajax jsp dojo dojo.data
  Using a form in a dialog box I am using Dojo in jsp to save the form in my database. After that request is completed using dojo.xhrPost() I am sending in another request to update a dropdown box that should include the added form object that was just saved, but for some reason the request to update the dropdown is executed before saving the form in the database even though the form save is called first. Using Firebug I can see that the getLocations() request is completed before the sendForm() re
