Parameter in Action mapping in Struts config xml problem

[mark watson]

Hi,

<action path="/sample" type="SampleAction" parameter="sampleParam" name="SampleForm" scope="session">
			<forward name="sampleForward" path="/SampleJSP.jsp"></forward>
</action>

1. /sample.do?sampleParam=search
2. /sample.do
3. /sample.do?sampleParam=

1 is working fine.
2 is handled using unspecified method
3 is throwing unhandled exception

is there any better way to handle the 3rd case? In 3rd case I want to forward them to specified error page instead of common error page.

Any suggestions appreciated, Thanks.

Mark.

Mark, provide more info regarding the 3 case (when, where and how it is happening).

Just to add, we can use global exceptions in struts-config with "type" attribute where we can define forward based on custom exception as well, but i didnt get the exact scenario of yours
