Use the log file generated in the % atat_home % \ logs directory

4. Now, you can use shutdown. BAT to release the port.

2. Test Tomcat

Enter http: // localhost: 8080 or http: // 127.0.0.1: 8080 in the address bar. If the following interface is displayed, the operation is successful.

3. Configure the Tomcat port number

In the % atat_home % \ conf directory, open servlet. XML in the text editor and find

 

<Connector Port = "8080" protocol = "HTTP/1.1" Connectiontimeout = "20000" Redirectport = "8443" type = "regxph" text = "yourobjectname"/>

Just change port = "8080" to the port you want.

Suggestion:Use a number larger than 1024.

4. Deploy the application

Two methods:

1. Manually deploy to webapps

Copy the web application to webapps under the Tomcat directory

2. virtual directory

In the % atat_home % \ conf directory, use a text editor to open servlet. xml and configure it in the host tab:

 

<Context Path = "/myweb" docbase = "H: \ 2t100 \ jspservlet \ myweb" reloadable = "true"/>

A context represents a web application,

Path: Virtual Path

Docbase: physical path of the web program

Reloadable: automatically reload page changes

Ii. directory structure of web programs

 

Directory	Description
/	The root directory of the Web application. Client Access, including JSP, HTML, and jpg And other resources.
WEB-INF	Stores various resources used by applications. Directory is not accessible to the client, including Web. XML (deployment descriptor)
/WEB-INF/classes	Store all the class files of the WEB Project
/Web-INF/lib	Store Jar files used by Web Applications

3. Manage Web applications in Tomcat

Click tomcatmanager.

Enter user name and password

Configure the user and password

Click "cancel" in, and the following message is displayed:

Then modify CONF/tomcat-users.xml

Add users in the format

 

<User Username = "Tomcat" Password = "123" roles = "Admin, Manager"/>

Enter the user name and password
