This seemed to do the trick along with creating my own
"custon_chain-config.xml"
<servlet>
....
<init-param>
<param-name>chainConfig</param-name>
<param-value>
org/apache/struts/chain/chain-config.xml,
/WEB-INF/custom-chain-config.xml
</param-value>
</init-param>
..
</servlet>
This works for defining an action via the catalog/command
<action path="/MyChainAction" catalog="mycat" command="mychain"
name="MyChainActionForm" validate="true" scope="request"
input="theinput.jsp">
<forward name="success"
path="thesuccess.jsp" />
</action>
I also had no problem getting things out of a form within a "command" eg:
public boolean execute(ActionContext context) throws Exception {
LazyValidatorForm theForm =
(LazyValidatorForm)context.getActionForm();
String somefield = (String)theForm.get("thefield");
...
context.getRequestScope().put("theresult", theresult);
return false;
}
