在myeclipse或者eclipse中新建一个class 命名为 MyEclipseGen ，拷贝下面的代码替换到MyEclipseGen.java 中，执行该类，获得subscritption code

import Java.io.*; public class MyEclipseGen {  private static String LL="Decompiling this copyrighted software is a violation of both your license agreement and the Digital Millenium Copyright Act of 1998(http://www.loc.gov/copyright/legislation/dmca.pdf).Under section 1204 of the DMCA,penalities range up to a $500,000 fine or up to five years imprisonment for a first offense.Think about it;pay for a license,avoid prosecution,and feel better about yourself.";  public String getSerial(String userId,String licenseNum){  java.util.Calendar cal =java.util.Calendar.getInstance();  cal.add(1,3);  cal.add(6,-1);  java.text.NumberFormat nf=new java.text.DecimalFormat("000");  licenseNum=nf.format(Integer.valueOf(licenseNum));  String verTime=new StringBuilder("-").append(new java.text.SimpleDateFormat("yymmdd").format(cal.getTime()))  .append("0").toString();  String type="YE3MP-";  String need = new StringBuilder(userId.substring(0,1)).append(type).append("300").append(licenseNum).append(verTime).toString();  String dx= new StringBuilder(need).append(LL).append(userId).toString();  int suf =this.decode(dx);  String code=new StringBuilder(need).append(String.valueOf(suf)).toString();  return this.change(code);  }  private int decode(String s){  int i;  char[] ac;  int j;  int k;  i=0;  ac=s.toCharArray();  j=0;  k=ac.length;  while(j<k){  i=(31 * i) + ac[j];  j++;  }  return Math.abs(i);  }  private String change(String s){  byte[] abyte0;  char[] ac;  int i;  int k;  int j;  abyte0=s.getBytes();  ac=new char[s.length()];  i=0;  k=abyte0.length;  while(i<k){  j=abyte0[i];  if((j >= 48) && (j<=57)){  j=(((j-48) + 5) % 10) + 48;  }else if((j >=65)&& (j <=90)){  j=(((j - 65) + 13) % 26) + 65;  } else if((j >=97) && (j <=122)){  j=(((j-97) + 13) % 26) + 97;  }  ac[i] =(char) j;  i++;  }  return String.valueOf(ac);  }  public MyEclipseGen(){  super();  }  public static void main(String[] args){  try{  System.out.println(" please input register name:");  BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));  String userId= null;  userId=reader.readLine();  MyEclipseGen myeclipsegen = new MyEclipseGen();  String res= myeclipsegen.getSerial(userId,"20");  System.out.println("Serial:" + res);  reader.readLine();  }catch(IOException ex){  }  }  }

MyEclipse –> Subscription Information 中输入生成的编码即可解决过期问题
