今天MyEclipse提示过期了,MyEclipse Trial Expired.

网上找到了一个注册类可以生成Myeclipse注册码.

146.   
147.                           BufferedReader reader = new BufferedReader(new InputStreamReader(      
148.   
149.                                   System.in));      
150.   
151.                           String userId = null;      
152.   
153.                           userId = reader.readLine();      
154.   
155.                           MyEclipseGen myeclipsegen = new MyEclipseGen();      
156.   
157.                           String res = myeclipsegen.getSerial(userId, "0");      
158.   
159.                           System.out.println("Serial:" + res);      
160.   
161.                           reader.readLine();      
162.   
163.                       } catch (IOException ex) {      
164.   
165.                       }      
166.   
167.                   }      
168.   
169.               }  

 

运行后效果如下:

 

修改String res = myeclipsegen.getSerial(userId, "20"); 中"20"为"0"可以变成Number of Licenses为Unlimited.

 

然后

然后将刚才生成的序列号输入

点击下面的Finish即可

代码测试过了，可行！

从Myeclipse--》subscription information 即可进入update subscription界面。

ok，现在可以了吧？恭喜你！
