[Cactus v2 - VOTE] Extension to web.xml mechanism

[Vincent Massol]

In order to be able to define different init values for different test
cases, we need to expand the current Cactus web.xml mapping mechanism.
Currently, in web.xml we define a single servlet : the Redirector Servlet,
as in :

    <servlet>
        <servlet-name>ServletRedirector</servlet-name>

<servlet-class>org.apache.commons.cactus.server.ServletTestRedirector</servl
et-class>
        <init-param>
          <param-name>param1</param-name>
          <param-value>value1 used for testing</param-value>
        </init-param>
    </servlet>


This is not good enough, as I cannot have 2 test cases with 2 different
"param1" values for example.

* Proposition : several test mappings in web.xml

I propose to write instead :

    <servlet>
        <!-- Default for all test cases when no testcase specific entry is
defined -->
        <servlet-name>ServletRedirector</servlet-name>

<servlet-class>org.apache.commons.cactus.server.ServletTestRedirector</servl
et-class>
    </servlet>

    <servlet>
        <servlet-name>ServletRedirector_XXX1</servlet-name>

<servlet-class>org.apache.commons.cactus.server.ServletTestRedirector</servl
et-class>
        <init-param>
          <param-name>param1</param-name>
          <param-value>value1</param-value>
        </init-param>
    </servlet>

    [...]

    <servlet>
        <servlet-name>ServletRedirector_XXX2</servlet-name>

<servlet-class>org.apache.commons.cactus.server.ServletTestRedirector</servl
et-class>
        <init-param>
          <param-name>param1</param-name>
          <param-value>value2</param-value>
        </init-param>
    </servlet>


The redirector URL defined in cactus.properties will be the prefix and will
get the testcase name prefixed to it. Cactus will have to scan the web.xml
file so that if no mapping is done on the name ServletRedirector_XXX it will
then use the URL defined in cactus.properties as is (with no suffixing).

I have no other simple ideas ...
