I use Struts 2.3.16.3. I want an action from webapp 1 to pass parameters to an action in webapp 2. In the struts.xml of webapp 1 I define the following result:
<result name="success" type="redirect">
<param name="location">http://localhost:8080/Webapp2/index.action</param>
<param name="testParam">testValue</param>
</result>
I expect my browser to redirect me to this webpage (a page in webapp2) when the result equals 'success':
http://localhost:8080/Webapp2/index.action?testParam=testValue
However, my browser takes me to:
http://localhost:8080/Webapp2/index.action
completely ignoring the parameter.
If I change my result to have everything inside the location param then it works, but you can see this gets very clunky with multiple params:
<result name="success" type="redirect">
<param name="location">http://localhost:8080/Webapp2/index.action?testParam=${testValue}</param>
</result>
This correctly redirects my browser to the url:
http://localhost:8080/Webapp2/index.action?testParam=testValue
Why does the first method not work?
If the
location
starts withhttp:
,https:
,mailto:
,file:
,ftp:
then it's used as a final location to redirect usingresponse.sendRedirect()
. Parameters in the result using<param>
tag in this case are ignored.
