Eclipse Web Development Project
I. Establishment of Development Environment1. Development Tools
JDK: jdk1.6.0 _ 17
Web server: APACHE-Tomcat-6.0.26
IDE: eclipse-jee-helios-SR1
2. Build a Development Environment
Because IDE is selected as the development tool, IDE can manually configure the required plug-in tool, so it is easy and quick to build a development environment.
(1) install JDK
Tip: After JDK is installed, You need to configure environment variables.
(2) install Tomcat
Tip: if the version is decompressed, decompress it directly. if the version is installed, complete the installation as prompted. Because IDE is used for development, you do not need to configure Tomcat environment variables. However, we recommend that you do not rely too much on IDE.
(3) decompress eclipse
Tip: If JDK is not installed, eclipse installation cannot be completed.
Now, the development environment is ready. Next, we will use a demo to demonstrate how to develop a web project in eclipse.
2. Develop a web project 1. Create a WEB Project
Eclips --> file --> New --> dynamic web project
Select New runtime under targetruntime to configure Web Server
Next>
Use browse to select the tomcat installation directory
Tip: note that the JRE version of Tomcat must be consistent with the JRE version of the project.
Finish>
After that, all the way to next until finish is OK.
The new web project structure is as follows:
2. Develop Servlet
Right-click the src in the projectexplorer view and choose new --> servlet.
Next> ......
Select the override service method to automatically generate code.
Of course, you can also manually compile the servlet, but do not forget to configure the servlet in Web. xml.
Then finish the servlet creation.
The source code of Hello. Java is as follows:
The Demo code is as simple as this.
3. Publish a WEB Project
After the WEB Project is created, the next task is to release the WEB Project on the Web server.
Window --> show views --> servers
Right-click the blank area of the servers view
New --> Server
After finishing, you can start Tomcat under servers.
After Tomcat is started, many Tomcat startup information is printed in the console.
If no exception occurs, the demo is successfully released.
It does not matter even if a warning message appears.
Access http: // localhost: 8080/demo/hello in the browser
If no exception information is displayed
Hello Servlet
Successfully tested servlet. ^_^
I just made a very simple demo and explained the problem.
Create a JSP file in the webcontent directory
Next> finish
The source code of index. jsp is as follows:
<% @ Page Language ="Java"Contenttype ="Text/html; charset = ISO-8859-1" Pageencoding =ISO-8859-1"%> <! Doctype HTML public "-// W3C // dtd html 4.01 transitional // en" "http://www.w3.org/TR/html4/loose.dtd"> <HTML> <Head> <Meta http-equiv ="Content-Type"Content ="Text/html; charset = ISO-8859-1"> <Title> insert title here </title> </Head> <Body> <H1 align ="Center"> Hello JSP </Body> </Html> |

Redeploy the demo project to see the effect.
