[OT] problem with displaytag column sorting in struts 1.2 web project
Hi All,
In my Struts 1.2.x webapp, I am getting some Patient records from
backend using my PatientManager businessObject (which uses Hibernate)
to send back a populated Patients List in the request scope. (Patient is
my bean).
I am feeding this patientsList to Displaytag table,
to show the data in a table.
Here's the code snippet for my jsp containing displaytag table.
http://rafb.net/p/artIJr98.html
Now, I want to sort this table based on the PatientID
when I click on the PatientID column.
I read in the Displaytag docs
http://displaytag.homeip.net/displaytag-examples-1.1/example-sorting.jsp
where it mentions the following :
If you want to allow the user to sort the data as it is coming back,
then you need to just do two things, make sure that the data returned
from your property implements the Comparable interface (if it doesn't
natively - use the decorator pattern as shown a couple of examples ago),
and then set the attribute sortable="true" on the columns that you want
to be able to sort by.
Following the above suggestion, I changed my Patient class to implement
Comparable interface and implemented the following compareTo method (as
following)
http://rafb.net/p/t0CR4Q98.html
Then I re-build my app and restart it on the server, the displaytag
table shows up fine. But when I click on the first column PtId, it
doesn't sort the table. I just get the Http404 error page.
Am I missing something ?
Please help,
thanks in advance,
robin.

Just put requestURI="/mypage.do" (where mypage.do==the page that
displays the table).

Try setting the requestURI attribute of the table itself?
