Hi,
here is the solution I found for my issue :
I have this form-bean and action definitions in the struts-config.xml :
----
<form-bean name="formXXX" class="default.formClassXXX" (...)>
(...)
</form-bean>
(...)
<action path="processFormXXX"
name="formXXX"
(...)>
(...)
</action >
----
In some identified cases (determined during run-time), I want the
java class "custom.formClassXXX" to be used for the implementation
of the form-bean "formXXX" instead of "default.formClassXXX".
My solution uses multiple module configuration (since struts 1.1) :
I create a new module configuration, let's say struts-custom.xml
in which I only declare the following :
----
<form-bean name="formXXX" class="custom.formClassXXX" (...)>
(...)
</form-bean>
(...)
<!-- The action have the same definition as in the struts-config.xml,
- except that local forward definition (if any) may have the attribute
- contextRelative set to "true"
-->
<action path="processFormXXX"
name="formXXX"
(...)>
(...)
</action >
----
I declare this new module in web.xml as follow :
----
(...)
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>(...)</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/conf/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>config/custom</param-name>
<param-value>/WEB-INF/conf/struts-custom.xml</param-value>
</init-param>
(...)
</servlet>
(...)
----
and, in the jsp page that contains the form, I make the following :
----
<[EMAIL PROTECTED] (...)
import="org.apache.struts.util.ModuleUtils"
(...) %>
(...)
<%
// determine wether the customClass needs to be used (true) or not (false)
boolean needsCustom= (...) ;
java.lang.String modulePrefix= "" ;
if (needsCustom) {
modulePrefix= "/custom" ;
}
ModuleUtils.getInstance().selectModule(modulePrefix,request,application) ;
%>
(...)
<html:form action="processFormXXX" (...) >
(...)
</html:form>
(...)
----
And this works fine !
