Error Java Corba BAD_PARAM -


i trying establish connection huawei u2000 nbi corba alarms using .ior file connect. have idl files compiled java. below main code initializing orb

package com.be.u2k;  import java.io.bufferedreader; import java.io.file; import java.io.filereader;  import org.omg.corba.orb;  import alarmirpsystem.alarmirp; import alarmirpsystem.alarmirphelper;  public class main {      public static void main(string[] args) {          try {           string filename = system.getproperty ("user.home") + system.getproperty ("file.separator")+"u2k.ior";            file f = new file(filename);            if (!f.exists()) {             system.out.println("file " + filename + " not exist.");             system.exit(-1);           } else if (f.isdirectory()) {             system.out.println("file " + filename + " directory.");             system.exit(-1);           }            bufferedreader br = new bufferedreader(new filereader(f));           string iorcontents = br.readline();           br.close();            orb orbwithior = orb.init(args, null);           org.omg.corba.object obj = orbwithior.string_to_object(iorcontents);            alarmirp alarmirp = alarmirphelper.narrow(obj);           system.out.println("alarmirphelper.narrow success!") ;         } catch (exception e) {           system.out.println("error : " + e) ;           e.printstacktrace(system.out);         }     } }

why keep getting bad_param error when running with

java -jar serveru2kalarm.jar

admin@ip-10-44-0-10:~$ java -jar serveru2kalarm.jar error : org.omg.corba.bad_param:   vmcid: 0x0  minor code: 0  completed: no org.omg.corba.bad_param:   vmcid: 0x0  minor code: 0  completed: no     @ alarmirpsystem.alarmirphelper.narrow(alarmirphelper.java:60)     @ com.be.u2k.main.main(main.java:36)

did miss out orb object? thanks.

i'm dealing same issue now. first have epirp hw u2000. here example code alarmirp.code not yet completed. ior of service used, relevant irpid , irpclassname must given in get_irp_reference method.

for manageridentifier read explanation: manageridentifier value
