just like that ,I read the source for short , it seems like that it needs a
file called jspwiki.properties which i think will be created by jspwiki itself,
but anyway ,I copy one from the source ,and put it in the place ,and restart
the tomcat ,no accident , exception occers again ,though it is a different one
,but i think the two may be caused by the same problem.Here follows the
exception:exceptionorg.apache.jasper.JasperException:
java.lang.NullPointerException
