Books on open-source software must provide software versions that match each other as much as possible

Failed to try the example of spring live. At the beginning, ant reported an error, but there was no way to change the method. I took out the project practice solution: SSH-based Java Development I bought a few days ago and followed the example in it. This book is not very good. It does not provide development tools and software on its own CD. You need to download it by yourself. Today's open-source software is changing every day, and it is very troublesome to match it yourself. There is no way to buy and use it. I can't purchase other books in the bookstore.

Myeclipse is still smooth and can be used after installation. The next step is to match tomcat. The book seems to be one step missing. Fortunately, I found a blog and finally matched it. Then it works with MySQL and driverProgramIt has changed to connector/J, and it is still smooth, and the database is connected. A new struts application has been created, so you can rest.

The advantage of this book is that many screen pictures are suitable for beginners. However, for different software versions, you can only make a reference. If there is no online search or good English, this book is basically useless and may be stuck in any place.

Come to an experience. Books on open-source software should try to provide a software version that matches well, so that readers can take medicine on their own.
