2, Use the registration code to crack MyEclipse, that is, this article.

3, Install SVN:

4, To configure Tomcat:

1, Start MyEclipse and set up the workspace

2, Create a new java project

Start with a first name and capitalize.

Create a new package, and copy the java file of the register.

Attached registration machine code:

3, After there are no errors, run the project

4, Enter any name and press enter

So you get the serial number.

5, Go to MyEcilpse to set the serial number

Done!
