Build error when compiling java methods in C++ using jni.h -

-

i'm trying run few methods java class in visual studio c++ environment. got error related createjavavm.

would please me find solution?

i did following steps.

step 1: jdk 1.6 installed under following path: c:\program files\java following 2 sub directories there: jdk1.6.0_45, jre6

step 2: write simple java program.

public class sample2 {    public static int intmethod(int n)    {      return n*n;    }    public static boolean booleanmethod(boolean bool)     {     return !bool;     }  }

step 3: compile java code:

   javac sample2.java

step 4: create visual studio c++ program. visual c++ clr console application.

step 5: add additional dependencies. (jvm.lib , jvm.dll) a) choose project -> properties -> linker -> input -> additional dependencies: jvm.lib b) choose project -> properties -> linker -> input -> delay loaded dlls: jvm.dll

step 6: add include directories a) choose project -> properties -> configuration properties -> c/c++ -> general -> additional include directories: c:\program files\java\jdk1.6.0_45\lib; c:\program files\java\jdk1.6.0_45\include\win32; c:\program files\java\jdk1.6.0_45\include

step 7: write c++ code run java methods. 

  #include "stdafx.h"   #include "jni.h"   #include <jni_md.h>   using namespace system;    int main(array<system::string ^> ^args)   {      javavm *jvm;   /* denotes java vm */     jnienv *env;  /* pointer native method interface */     jint square;     jboolean not;      javavminitargs vm_args; /* jdk/jre 6 vm initialization arguments */      javavmoption *options = new javavmoption[1];      options[0].optionstring = "-djava.class.path=c:\\javacode";       vm_args.version = jni_version_1_6;    vm_args.options = options;    vm_args.noptions = 1;    vm_args.ignoreunrecognized = false;     int res = jni_createjavavm(&jvm, (void **)&env, &vm_args);     jclass cls = env->findclass("sample2");     jmethodid mid = env->getstaticmethodid(cls, "staticint", "(i)i");     env->callstaticvoidmethod(cls, mid,10);     if(cls !=0)    {         mid = env->getstaticmethodid(cls,"intmethod","(i)i");         if(mid !=0)    {       square = env->callstaticintmethod(cls, mid, 5);            printf("result of intmethod: %d\n", square);    }     mid = env->getstaticmethodid(cls, "booleanmethod", "(z)z");      if(mid !=0)     {       not = env->callstaticbooleanmethod(cls, mid, 1);      printf("result of booleanmethod: %d\n", not);     }  }   jvm->destroyjavavm();   console::read();  return 0; }

step 8: when build project got following error: 

1>------ build started: project: 1, configuration: debug win32 ------  1>link : warning lnk4199: /delayload:jvm.dll ignored; no imports found jvm.dll  1>1.obj : warning lnk4248: unresolved typeref token (0100000f) '_jmethodid'; image may not run  1>1.obj : error lnk2028: unresolved token (0a000016) "extern "c" long __stdcall jni_createjavavm(struct javavm_ * *,void * *,void *)" (?jni_createjavavm@@$$j212ygjpapaujavavm_@@papaxpax@z) referenced in function "int __clrcall main(cli::array<class system::string ^ >^)" (?main@@$$hymhp$01ap$aavstring@system@@@z)  1>1.obj : error lnk2019: unresolved external symbol "extern "c" long __stdcall jni_createjavavm(struct javavm_ * *,void * *,void *)" (?jni_createjavavm@@$$j212ygjpapaujavavm_@@papaxpax@z) referenced in function "int __clrcall main(cli::array<class system::string ^ >^)" (?main@@$$hymhp$01ap$aavstring@system@@@z)  1>c:\users\tveluppillai\desktop\test1\1\debug\1.exe : fatal error lnk1120: 2 unresolved externals  ========== build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

would me solve error please?

jni_createjavavm defined in jni.h, guess linker not finding jni.h. put file , jni_md.h in project directory source code.

note jni.h includes jni_md.h, having #include <jni_md.h> in source code redundant.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
