Hi All,
I need to set <html:link> as a post method, caz I need to avoid the parameter values to be
catched in the histories in case of the GET method request.
can anyone send me some suggestions.
Thanks,
Thanigai M.

They are passed anyway, but if there is an ActionForm, the parameters
are got and put into the corresponding property, not the opposite.

Good luck!

Hi Antonio,
Thanks for your response.
1. I am not using any filter and if i am not wrong,
then tomcat 3.3.2 does support filters since it
implements servlet 2.2 specs.
Other thing is that I am not using any ActionForm for
this Action. My Action is below:
<action
path="/print"
type="com.abc.myap.Actions.PrintableAction"
scope="request">
</action>
Since I am just passing couple of parameters on the
html:link to action and I am able to get those using
getQueryString(). Then I just split them from there
and use them. Atleast it keeps me going. I am not sure
if paramters from html:link are passed only if the
corresponding action has a ActionForm.
I will check this with latest version of tomcat later
on.
Thanks

Mmm... Did you try to use the latest Tomcat? It really could be the
container.

No, I mean, since Struts' ActionForm is populated using "getParameter",
as it returns null, the parameter is not passed to the corresponding
property too!
Now you should check if you are using a filter and:
1) if yes, debug your application to see what's the name of the class of
the instance of HttpServletRequest: if it is not a Tomcat's one, I would
suspect there's a bug in the filter;
2) if no, it could be a container problem, check it using the latest
Tomcat version.
Please let me know.
Ciao
Antonio

Hi Antonio,
When I Printed getQueryString in the action class
using the below stmt
System.out.println("request.getQueryString() =
"+request.getQueryString());
Result was
request.getQueryString() = print=1
So it means, Query string has print parameter but
request.getParameter("print") is returning null in the
action class.
I am using tomcat 3.3.2 and struts 1.2.9
Is there any other way to retrive this parameter other
than using getParameter?
Thanks
