Hi Shinya
I created a test file called test.jsp and placed in
/usr/local/tomcat/jakarta-tomcat-4.1.31/webapps/examples/jsp/
and accessed http://localhost:8080/examples/jsp/test.jsp
The test.jsp contains
<%= request.getParameter() %>
<%= request.getParameterNames() %>
I am getting
*type* Exception report
*message* **
*description* *The server encountered an internal error () that prevented it
from fulfilling this request.*
*exception*
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 0 in the jsp file: /jsp/test.jsp
