please help ... I have removed whitespaces by adding
<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<trim-directive-whitespaces>true</trim-directive-whitespaces>
</jsp-property-group>
</jsp-config>
but still i am facing same error. I tried to increase the buffer size also
as,
<%@ page buffer="800kb" autoFlush="false" %>
but still same error....
stuck on this issue for more than 2 weeks now and need to close it ASAP
please help.
Any help/ pointer would be highly appreciated.
one more things, we are using struts version 1 and tiles 2.2. as struts1
doesn't work with tiles2, we have used struts-tiles2-1.4.0-SNAPSHOT.jar,
can this create any problem, but this combination work with tomcat version
below 7.0.37 and giving issues from version 7.0.39.
Can anybody please tell me what are the changes in between these two
versions which can produce this errror ??
Thanks
