Using multiple Struts configuration files

Multiple profiles (single module)

<servlet>
　<servlet-name>action</servlet-name>
　<servlet-class>
　　org.apache.struts.action.ActionServlet
　</servlet-class>
　<init-param>
　　<param-name>config</param-name>
　　<param-value>
　　　/WEB-INF/struts-config.xml,
　　　/WEB-INF/struts-config-2.xml
　　</param-value>
　</init-param>
　<load-on-startup>1</load-on-startup>
</servlet>

When Actionservlet is loaded, Struts merges multiple files into a single file in memory.

Struts 1.1 introduces support for multiple configuration files. Each configuration file must be a valid XML file and must conform to the Struts-config XML DTD. The value of the initialization parameter Config in which these files can be declared as Actionservlet in Web.xml. You can specify these files as a comma-delimited list of paths. At run time, these files are merged into one file in memory. If duplicate elements occur, such as two different form bean declarations with the same name attribute, the last read-in configuration takes precedence.

Multi-configuration file (multiple modules)

<servlet>
<servlet-name>action</servlet-name>
<servlet-class>
Org.apache.struts.action.ActionServlet
</servlet-class>
<init-param>
<param-name> Config</param-name>
<param-value>
/web-inf/struts-default-config.xml,
/WEB-INF/struts-def Ault-config-2.xml
</param-value>
</init-param>
<init-param>
<param-name> Config/module1</param-name>
<param-value>
/web-inf/struts-module1-config.xml
</ Param-value>
</init-param>
<init-param>
<param-name>config/module2</ Param-name>
<param-value>
/web-inf/struts-module2-config.xml,
/web-inf/struts-module2-config -2.xml,
/web-inf/struts-module2-config-3.xml
</param-value>
</init-param>
<load-on- Startup>1</load-on-startup>
</servlet>

Each module is defined by its own configuration file. Each struts application implicitly has a default module. The default module has no name. Additional modules are defined by specifying a module prefix. The prefix is the value immediately following the config/in the Actionservlet initialization parameter of struts.
