Summary: Export error - Filter not working
Initial Comment:
I have problems exporting data with DisplayTag and
Tomcat 4.0.15, so I tried the new ResponseOverrideFilter
. But the filter it's not working. I look a little in the code
and i think that the problem is that:
- In ResponseOverrideFilter CONTENT_OVERRIDE_BODY
and CONTENT_OVERRIDE_TYPE are defined like that
ResponseOverrideFilter.class.getName() +
"CONTENT_OVERRIDE_BODY"; Note that there are not
point between the className and the string constant.
- And in the TableTag it search the request for the
parameter with point like that: StringBuffer bodyBuffer =
(StringBuffer) request.getAttribute("org.displaytag.filter.
ResponseOverrideFilter.CONTENT_OVERRIDE_BODY");
So the ResponseOverrideFilter is never used really.
I try the ResponseOverrideFilter with the right definition
of CONTENT_OVERRIDE_BODY and
CONTENT_OVERRIDE_TYPE and it's working althougth
Tomcat trace a lot of "java.lang.IllegalStateException:
Cannot call getWriter() after getOutputStream()".
