Ok here it goes. Instead of populating custom UserBean I populate
UserForm Bean in EditUserAction. The form is the same that is also
used in UpdateUserAction and InsertUserAction. I know that struts
guidelines say that reuse you action classes, but I like separating these
different actions in different action classes because I'm quite new to
this Java World and I'm not using EJBs. This works for me. If you
are planning bigger application then it is recommended to use EJBs,
but the timeframe in this project is so tight so I have no time to learn
all those fancy Java APIs and Patterns.
My Mappings looks like this:
<form-beans>
<form-bean name="UserForm"
type="com.projectcast.sfundm.UserForm"/>
</form-beans>
<action-mappings>
<action path="/userlist"
type="com.projectcast.sfundm.UserListAction"
name="UserForm"
scope="request"
validate="false">
<forward name="success"
path="/WEB-INF/web/userlist.jsp"/>
<!-- this is redundant as it forwards to same place
as success, but it is here so I can change it if
I want and Action class remains unchanged -->
<forward name="failure"
path="/WEB-INF/web/userlist.jsp"/>
</action>
<action path="/edituser"
type="com.projectcast.sfundm.UserSelectAction"
name="UserForm"
scope="request"
validate="false">
<forward name="success"
path="/WEB-INF/web/edituser.jsp"/>
</action>
<action path="/updateuser"
type="com.projectcast.sfundm.UserUpdateAction"
name="UserForm"
scope="request"
input="/edituser.do"
validate="true">
<forward name="success"
path="/userlist.do"
redirect="true"/>
<forward name="cancel"
path="/userlist.do"
redirect="true"/>
</action>
<action path="/insertuser"
type="com.projectcast.sfundm.UserInsertAction"
name="UserForm"
scope="request"
input="/userlist.do"
validate="true">
<forward name="success"
path="/userlist.do"
redirect="true"/>
</action>
<action path="/deleteuser"
type="com.projectcast.sfundm.UserDeleteAction"
scope="request"
input="/userlist.do"
validate="false">
<forward name="success"
path="/userlist.do"/>
</action>
</action-mappings>
Pretty weird, huh!
