Use eclipse 3.1 WST to compile struts File Upload

You can download the WST with eclipse3.1 file on eclipse.org. This file includes eclipse3.1 and WST and all the plug-ins it requires. Basically, no other plug-ins are required.

After unpacking the downloaded file, create a new project: Dynamic Web project, which is the Web server for configuration and debugging. In Tomcat 5.5, enter the installation directory of Tomcat 5.5.

Copy the lib and TLD files required by struts to the WEB-INF directory

Write the WEB-INF in the struts-config.xml/config directory as follows

<? XML version = "1.0" encoding = "ISO-8859-1"?>

<! Doctype Struts-config public
"-// Apache Software Foundation // DTD struts configuration 1.2 // en"
Http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd>

Debug welcome. jsp. Eclipse will start Tomcat and print the startup log in the console, where: Web. xml cannot be found appears.

This error can be ignored.

Select a file and click Submit of index. jsp. The program jumps to functionimportaction. If you set a breakpoint in functionimportaction, you can stop at the break point. Very convenient.
