Error opening jar on command line

Question

I have the following code and am using a library to list the citizen card fields.

When I try to run in the DOS it doesn’t work.

import java.io.*;
import pteidlib.*;
public class main {

        public String nome;
        public String data;
        public String pais;
        public String sexo;


        static
          {
            try
            {

                System.loadLibrary("pteidlibj");


            }
            catch (UnsatisfiedLinkError e)
            {
              System.err.println("Native code library failed to load.\n" + e);
              System.exit(1);
            }
          }


        public void PrintIDData(PTEID_ID idData) throws FileNotFoundException, UnsupportedEncodingException
          {
                nome = idData.firstname + " " + idData.name ;
                data =  idData.birthDate;
                pais = idData.country;
                sexo = idData.sex;
                    PrintWriter writer = new PrintWriter("the-file-name.txt", "UTF-8");

           writer.println(nome);   
            writer.println(data);
            writer.close();
                System.out.print(nome);
          }


    public static void main(String[] args) throws UnsupportedEncodingException, FileNotFoundException, PteidException{
              main  test = new main();

           pteid.Init("");
      //test.TestChangeAddress();
        // Don't check the integrity of the ID, address and photo (!)
      pteid.SetSODChecking(false);

      int cardtype = pteid.GetCardType();
      switch (cardtype)
      {
          case pteid.CARD_TYPE_IAS07:
              System.out.println("IAS 0.7 card\n");
              break;
          case pteid.CARD_TYPE_IAS101:
              System.out.println("IAS 1.0.1 card\n");
              break;
          case pteid.CARD_TYPE_ERR:
              System.out.println("Unable to get the card type\n");
              break;
          default:
              System.out.println("Unknown card type\n");
      }

      // Read ID Data
      PTEID_ID idData = pteid.GetID();
      if (null != idData)
      {
        test.PrintIDData(idData);
      }


}
}

I need to run this on the command line java -cp test.jar main and then being called on the command line gives me this error:

Answer 1

Adding to the @user2964140 response, and assuming the library is in c: as you said, the command to execute should be:

java -cp .;c:\suabiblioteca.jar -jar test.jar

This response assumes that your test.jar jar jar was done correctly (i.e., it includes a MANIFEST.MF with the header that speaks which class contains your method public static void main(String args[]).
If this is not the case, it is advisable to read the Oracle tutorials on how to create jars and manifest files.

One last suggestion is to include your library in the directory lib/ inside your jar, so that your application contains everything you need.
