As shown in figure:

Note: The variable value of the Classpath item is preceded by a bit, and the path's variable value is generally added to the front of the original value, if added to the back to be separated by a semicolon

4, verify the installation success or not: "Start"->; " Run ", type" cmd ", type the command" Java-version "," Java "," Javac "several commands, appear the screen, indicating the success of environment variable configuration;

Second, the installation of Tomcat

1, download Apache-tomcat-6.0.35.exe, about 7M, I this is the installation package (compression package directly decompression can), double-click Run all the way next can be installed, which can also configure the installation path, I keep the default path, the port is also the default 8080.

3, copy the com.sysdeo.eclipse.tomcat_3.3.0 folder to the Eclipse directory in the Plugins plugins folder, I am here C:\eclipse\plugins, the following figure:

4, run Eclipse, set workspace, I set up in C:\workspace, run Eclipse after the toolbar will appear Tomcat toolbar, if not check the previous steps, as shown:

5, then the Eclipse configuration, first JRE, generally this is already configured, the following figure:

6, then the Web application server configuration, the following steps:

5, a new table, you can use the interface to create, or you can use SQL statements, the following figure:

6, double-click the corresponding table, you can open the table for data add Modify Delete, the following figure:

Summary: The Java Web Development environment has been basically built up, if time runs, the next article to write an example program and share!
