Java JNI: How to set String [ ] field Of Java class from native method of C++ -


i have class : processsolution 

public class processsolution {     private string processid;     private string processname;     private string processsolutionsteps [];     private string processremark;     private string processnote; }

and want set 1 of field processsolutionsteps native method ,

here step_name nothing processsolutionsteps 

jniexport jobjectarray jnicall java_nativeclass_jmain_getprocesssolutions   (jnienv *env, jobject jobject) {     clientlist *cl = new clientlist();     jmp_buf jmpb;     int i, j , k;     int listcount = 0, steps = 0;     jobjectarray arrps = null;     jobject clsobj;     struct process *list = null;     struct procdtl *pdtl;     char *remark, *note, *step_name;      list = (struct process *)calloc (sizeof(process)  , 1);     pdtl = (struct procdtl *)calloc (sizeof(procdtl)  , 1);     remark = (char*) calloc(201 ,1);     note = (char*) calloc(201 ,1);     step_name = (char*) calloc(201 ,1);      cl->get_proc_list ( &listcount, &list );      jclass clsps = env->findclass("pojo/processsolution");     if( clsps == null )         return null;     if( ( arrps = env->newobjectarray( listcount, clsps, null ) ) == null );         longjmp(jmpb,-1);     ( = 0; < listcount; ++i ) {             remark = get_proc_remark (list[i].proc_id);             note = get_proc_note (list[i].proc_id);             get_proc_list (list[i].proc_id ,  &steps, &pdtl);              (j = 0; j < steps; j++) {                 memset(step_name, ' ', 200);                 strcpy(step_name, pdtl[j].desc[0]);                 if (data_in(ps.desc[1]))                     sprintf(step_name+strlen(step_name), "%s", pdtl[j].desc[1]);                 if (data_in(ps.desc[2]))                     sprintf(step_name+strlen(step_name), "%s", pdtl[j].desc[2]);                 if (data_in(ps.desc[3]))                     sprintf(step_name+strlen(step_name), "%s",pdtl[j].desc[3]);                 if (data_in(ps.desc[4]))                     sprintf(step_name+strlen(step_name), "%s", pdtl[j].desc[4]);              }      }   }

my question how set processsolutionsteps [] above c++ method ?

thank you

jfieldid procsolstepsid = env->getfieldid(clsps, "processsolutionsteps", "[ljava/lang/string;"); jclass clsstr = env->findclass("java/lang/string"); (i = 0; < listcount; ++i) {     jobject procsolobj = env->newobject(clsps, env->getmethodid(clsps, "<init>", "()v"));     jobjectarray solsteps = env->newobjectarray(steps, clsstr, null);     (j = 0; j < steps; ++j) {         // prepare step_name         env->setobjectarrayelement(solsteps, j, env->newstringutf(step_name));     }     env->setobjectfield(procsolobj, procsolstepsid, solsteps);     env->setobjectarrayelement(arrps, i, procsolobj); }
