MyEclipse提示MyEclipse Trial Expired(试用期过),破解方法

1、建立Java Project，随便命名，只要符合规则就行。 

2、在刚刚建好的Project右击src，新建一个类，命名为MyEclipseGen，再把下面的代码复制到文件中。

运行，按照提示输入一串字符，建议取名字的首字母，然后回车，会出现一串注册码，然后复制注册码。

import java.io.*;  
  
public class MyEclipseGen {  
private static final 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).

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;

int i;  
int k;  
int j;  
abyte0 = s.getBytes();  
ac = new char[s.length()];

} 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) {  
}  
}  
}  

　　

3、根据提示在console输入register name

4、然后MyEclipse –> Subscription Information，按提示第一行输入你刚刚输入的字符串，第二行粘贴注册码，点击Finish即可.
