Exception: [.TableTag] Unable to reset response before returning exported data.
September 3, 2008
Problem :
Exception: [.TableTag] Unable to reset response before returning exported data. You are not using an export filter. Be sure that no other jsp tags are used before display:table or refer to the displaytag documentation on how to configure the export filter (requires j2ee 1.3).
Context :
When displaytag exports data in any non-html format, it needs to change the content type returned to the browser and reset any other content generated by the surrounding page.
Sometimes this can’t be done: if content has already been sent back to the user, the response can’t be reset and you get an error. This could happen because too many chars have been already written to the response, so that the response buffer was full and response has been automatically flushed.
Solution :
Add the following to the page…
<%@ page buffer = "16kb" %>
Reference :
… Wa Allahu A’lam

I’ve found a different solution after talking to a collegue…
in the web.xml add..
ResponseOverrideFilter
org.displaytag.filter.ResponseOverrideFilter
and map the filter around the requestURI you are using on the display tag:
ResponseOverrideFilter
/my_report.action
I’m guessing this is an export filter

(last post striped out my xml)
I’ve found a different solution after talking to a collegue…
in the web.xml add..
<filter>
<filter-name>ResponseOverrideFilter</filter-name>
<filter-class>org.displaytag.filter.ResponseOverrideFilter</filter-class>
</filter>
and map the filter around the requestURI you are using on the display tag:
<filter-mapping>
<filter-name>ResponseOverrideFilter</filter-name>
<url-pattern>/my_report.action</url-pattern>
</filter-mapping>
I’m guessing this is an export filter
