I am using strust2 for my web application development. My struts.xml file will be like:
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<package name="default" extends="struts-default" namespace ="/">
<action name="signup">
<result>/check.jsp</result>
</action>
</package>
</struts>
and my web.xml file will be something like:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<servlet>
<servlet-name>My WS</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.dr1.dr2</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>My WS</servlet-name>
<url-pattern>/checking</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
and now, if i access like: http://localhost:8080/appName/ its going to my signup action perfectly. But when i tried to access like http://localhost:8080/appName/checking (for webservices), Its even looking in struts.xml and getting an error message like:
HTTP Status 404 - There is no Action mapped for namespace / and action name checking... even after defining this in web.xml..
Is there any way to exclude a pattern in struts2, so that when I hit http://localhost:8080/appName/checking, it must not look struts action, it must call my default page path defined in web.xml file.
Thanks..
you can probably add exclude pattern in your struts.xml, something like
<struts>
<constant name="struts.action.excludePattern" value="appName/checking"/>
</struts>
read here and find excludePattern for more information.
this could works:
<!-- exclude pattern -->
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/struts/*</url-pattern>
</filter-mapping>
an action exampe:
<constant name="struts.action.excludePattern" value="appName/checking"/>
the constant excludePattern explicit exclusions (since 2.1.7)
