Problem regarding DispatchAction

[mihir maniar]

i have a class UserAction which extends DispatchAction Class.This class has 2 methods "Add" and "Modify" to perform different actions on the database and i then implement them.i make the necessary changes in the struts-config.xml.
<action-mappings> <action path="/User" type="com.actions.login.UserAction" parameter="process" />
</action-mappings>

Now i want to implement some links on a jsp page with the parameter that decides which method is to be called inside this DispatchAction class of mine. So my question is how do i write the parameter "process" in the following scenario while creating the link on the jsp page.
<html:link action="User">Modify</html:link>
<html:link action="User">Add</html:link>

i hope i am descriptive enough to make situation clear.THx in advance,

Hi Mihir,

In your case, I hope the following would solve the problem :

<html:link action="User.do?process=modify">Modify</html:link>
<html:link action="User.do?process=add">Add</html:link>

when i implement this solution it still gives me the error "page cannot be found" but the websphere does not give any error.Is there any elementary mistake that i am doing? Please help. Thank you.

Hi again!
In the segment of the struts-config.xml, that you've attached I fing that there's no entry for even a single forward.
What does your com.actions.login.UserAction class's execute method return? Since there's no forward sub element in the "action" tag, there must be a global forward which is returned from the "UserAction" class. If its not the case, then I hope something is missing.
Can you paste the action class's execute method body? And also the corresponding "action-mapping" ?

Thanks & Regards,
Naresh

this is my struts-config file.

<action path="/User"
type="com.actions.login.UserAction"
parameter="process">
<forward name="success1" path="/jsp/success1.jsp"></forward>
<forward name="success2" path="/jsp/success2.jsp"></forward>
<forward name="success3" path="/jsp/success3.jsp"></forward>
</action>


this is my action class i.e. useraction.java

Hi!

new ActionForward("success1");

mapping.findForward("success1");

Hope this works.

if i call the link http://.../User.do?process=modify then it works but the way u suggested me earlier i.e. to put it in the html:link tag still doesn't work. ne other ideas. and yes could you plz ealborate what is the difference between the "mapping.findforward" and "new ActionForward" ways which made the difference in my case. Thx in advance.
