Tomcat 6 Default Buffer Size

Is there a way to set the default buffer size for JSP in Tomcat? I know that I can install them on every page, but I hope that somewhere there is a global option.

Short answer: None.

Long answer: Perhaps with some hacks ...

  • You will need to create Tomcat yourself after editing this class: Jasper constants
  • ... or you can make a Perl pie and edit all of your JSPs all at once. First back up, as this edits the line:

For directives without a set of buffers:

/usr/bin/perl -pi -e 's|<%@ page|<%@ page buffer="new" |g' `find . -type f -name '*.jsp'`

For buffers already configured:

/usr/bin/perl -pi -e 's|buffer="old"|buffer="new"|g' `find . -type f -name '*.jsp'`
