Subject RE: Accessing a servlet
Date Wed, 12 Jul 2006 14:43:42 GMT
If the url-pattern should be /firstpack/JustALittleTest then should the
form on the JSP refer to action="firstpack.JustALittleTest" or
action="firstpack/JustALittleTest" ?

Subject: RE: Accessing a servlet

When I use this entry I get a request resource not found error.

    <servlet>
       <servlet-name>JustALittleTest</servlet-name>
       <servlet-class>firstpack.JustALittleTest</servlet-class>
    </servlet>

    <servlet-mapping>
       <servlet-name>JustALittleTest</servlet-name>
       <url-pattern>/firstpack/JustALittleTest</url-pattern>
    </servlet-mapping>

Under the previous error to this one I was using an entry of:

    <servlet>
       <servlet-name>JustALittleTest</servlet-name>
       <servlet-class>JustALittleTest</servlet-class>
    </servlet>

    <servlet-mapping>
       <servlet-name>JustALittleTest</servlet-name>
       <url-pattern>/firstpack.JustALittleTest</url-pattern>
    </servlet-mapping>

With the following entry:

    <servlet>
       <servlet-name>JustALittleTest</servlet-name>
       <servlet-class>firstpack.JustALittleTest</servlet-class>
    </servlet>

    <servlet-mapping>
       <servlet-name>JustALittleTest</servlet-name>
       <url-pattern>/firstpack.JustALittleTest</url-pattern>
    </servlet-mapping>

I get an error of 'Error allocating a servlet instance'

<servlet>
   <servlet-name>TheServletName</servlet-name>
   <servlet-class>package.ThisIsTheClassName</servlet-class>
</servlet>
<servlet-mapping>
   <servlet-name>TheServletName</servlet-name>
   <url-pattern>/a/path/to/theservlet</url-pattern>
</servlet-mapping>

"servlet-name" is used to link the definition to the mapping.
defs are grouped together in web.xml, as are mappings.

"url-pattern" refers to the path by which you'll access the servlet.
it can any unique url on your system, and does not have to reflect the
class name.
