commons-chain: missing context parameter

Hello to all,

  On the cookbook, section "Load a Catalog From a Web Application", it is
missing this piece on the given web.xml.

    <context-param>
        <param-name>org.apache.commons.chain.CONFIG_ATTR</param-name>
        <param-value>catalog</param-value>
    </context-param>
    <context-param>


  I checked 
org.apache.commons.chain.web.ChainListener.contextInitialized(...) source
and it says CONFIG_ATTR is deprecated. I think this is also wrong. If so,
why do I need to declare it on the web.xml? It could also be a bug on the
method implementation.

  Regards,

Pedro

  Still not working :( The catalog is null.
  If I specify org.apache.commons.chain.CONFIG_ATTR on my web.xml the
catalog is no longer null but it does not contain any commands.

  I have looked at the source code severall times and I don't know where is
the problem. Help?





I have appended a logger to commons-chain and commons-digester... here are
the results :

** commons-chain log

15:46:17,970 - INFO org.apache.commons.chain.web.ChainListener -
Initializing chain listener
15:46:18,050 - DEBUG org.apache.commons.chain.web.ChainResources - Loading
chain config resource 'chain-config.xml'


** commons-digester log

does not provide any information about commons-chain parse operation (?)


My configuration :

** chain-config.xml (that is being copied to the WEB-INF/classes)

<?xml version="1.0" encoding="UTF-8" ?>
<catalogs>

    <catalog name="risks">


        <command
            name="viewRiskTypes"
            className="package.commands.ViewRiskTypes"/>

    </catalog>

</catalogs>

** web.xml (Tomcat-5.0.27)

 <context-param>
    <param-name>org.apache.commons.chain.CONFIG_CLASS_RESOURCE</param-name>
    <param-value>chain-config.xml</param-value>
 </context-param>

 <listener>
   <listener-class>
     org.apache.commons.chain.web.ChainListener
   </listener-class>
 </listener>

Setting a context init parameter to define the catalog name was the
original configuration mechanism.  However, configuration was later
enhanced so you can specify the catalog name on a <catalog> element
directly in your config file, and therefore even load different
catalogs from the same document:

    <catalogs>
        <catalog name="foo">
            ... commands for catalog "foo" ...
        </catalog>
        <catalog name="bar">
            ... commands for catalog "bar" ...
        </catalog>
    </catalogs>
