index.html ignored or default servlet got priority over index.jsp and index.html? Why?

Question

web.xml

<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">

  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>



<servlet>
    <servlet-name>ser1</servlet-name>
    <servlet-class>com.gaurav.test.Hello</servlet-class>    
</servlet>

<servlet-mapping>
    <servlet-name>ser1</servlet-name>
    <url-pattern>/</url-pattern>    
</servlet-mapping>

</web-app>

index.html

<body>
HelLoSTHTML
</body>

index.jsp

<body>
HelLoSTJSP
</body>

Hello.java,implementing javax.servlet.Servlet

service method

PrintWriter out=paramServletResponse.getWriter();
out.println("HelloTextStart");
out.println(config);
out.println("HelloTextEnd");
out.close();

deployed on jboss-5.1.0GA

now cases

**requesting

/TestFilter1/

** showing

"HelloTextStart org.apache.catalina.core.StandardWrapperFacade@1a878065 HelloTextEnd "

but not showing

"HelLoSTHTML"
**requesting

/TestFilter1/index.html

** then also showing

"HelloTextStart org.apache.catalina.core.StandardWrapperFacade@1a878065 HelloTextEnd "

but not showing

"HelLoSTHTML"
**requesting

/TestFilter1/index.jsp

** showing

"HelLoSTJSP"

So what is the order of processing/prioritizing this request? (html,jsp.Servlet ser1)

AFAIK it process from top to bottom if it dont find the file then goes for the next one — SparkOn, Jul 09 '14 at 13:52

Your application works as configured. You tell to your webapp : When you see request coming send them to the servlet class com.gaurav.test.Hello

Conf:

<servlet>
    <servlet-name>ser1</servlet-name>
    <servlet-class>com.gaurav.test.Hello</servlet-class>    
</servlet>

<servlet-mapping>
    <servlet-name>ser1</servlet-name>
    <url-pattern>/</url-pattern>    
</servlet-mapping>

So this servlet is responding to your request. I think want you need is to configure the servlet javax.servlet.Servlet

I hope this will help

how to configure the servlet javax.servlet.Servlet? – shrotriya Jul 09 '14 at 13:29
Replace com.gaurav.test.Hello by javax.servlet.Servlet – Pracede Jul 09 '14 at 14:13
javax.servlet.Servlet is an interface this can not instantiate. – shrotriya Jul 09 '14 at 16:25

we can configure the URL-patterns in 3 ways

1) Absolute/Exact Matching (Ex: <url-pattern>/test1</url-pattern>)
2) Extension Matching      (Ex: <url-pattern>*.do</url-pattern>)
3) Directory Matching      (Ex: <url-pattern>/abc/*</url-pattern>)

<url-pattern>/</url-pattern> means Every Request go to Hello.java

First it will check Exact matching then Extension there after Directory Matching.

Above code for every request is going to Hello.java.

go through this link you will get clarity which one will be given priority in Tomcat 6: index.html or index.jsp?
