[jboss-user] JBoss 5 SSI recursive?

Hello List, does anybody know if recursive SSI includes are generally possible in Jboss AS 5 ? I have a main.jsp with includes header.shtml. header.shtml includes another page headerContent.html. If I request header.shtml directly, headerContent.html is includes as expected. But requesting main.jsp includes only the header.shtml. The content of headerContent.html ist missing then. Kind regards Sascha
