Hello, I am trying to use Java methods into LV. I am doing so by creating Java Invocation Interface, usind which I can call Java methods into C++ and then create a shared library that can be called into LV. When I am importing my shared library into Labview, I am getting the following error messages: "The shared library contains 3 function(s). But no function is found and recognized in the header file. The following function(s) cannot be wrapped. If you want to import these functions, please review the warning messages next to the functions below. You will need to fix the problems before you can continue with the wizard. jclass invokeJavaClass(JNIEnv* jenv, string className);The following symbols are not defined:jclass; Undefined symbols can prevent the wizard from recognizing functions and parameters. To correct this problem, check the header file to determine if you must add preprocessor definitions. Click the Back button to return to the previous page of the wizard to add a preprocessor definitionsl (for example, "NIAPI_stdcall = __stdcall" or "NIAPIDefined = 1").The following header file was not found in the specified header file or one of the referenced header files:- string- iostream- cstring- jni.hTo fix, click the Back button to go to the previous page and add the header file path to the Include Paths list. " Please advise. Regards,H

Hi siadajpan,

Are you able to get a simple DLL to import correctly? Have you taken a look at either of these?
