I am a new Tomcat user.
I installed Tomcat 5.5 for use within IBM RAD/Eclipse runtime environment.
My goal is to find out how J2EE container managed (form based) security
works in Tomcat.
I started off by creating a JSF page, PH001, in the WebContect. No
security entry is specified in the web.xml file yet. I was able to run
and display the page.
Then I tried to check the Server Security Enable box and restart Tomcat to
run the same JSF page. I got the following exception:
Caused by: java.security.AccessControlException: Access denied
(java.util.PropertyPermission
org.apache.jasper.runtime.BodyContentImpl.LIMIT_BUFFER read)
at java.security.AccessController.checkPermission(
AccessController.java:104)

... 64 more
The default catalalina.policy file in the server is appended below : What
update do I need in the file to bypass the exception ? Thank you in
advance for any help.

// You can assign additional permissions to particular web applications by

// Different permissions can be granted to JSP pages, classes loaded from

// directory, or even to individual jar files in the /WEB-INF/lib/
directory.
//
// For instance, assume that the standard "examples" application
// included a JDBC driver that needed to establish a network connection to
the
// corresponding database and used the scrape taglib to get the weather
from
// the NOAA web server. You might create a "grant" entries like this:
//
// The permissions granted to the context root directory apply to JSP
pages.
// grant codeBase "file:${catalina.home}/webapps/examples/-" {
// permission java.net.SocketPermission "dbhost.mycompany.com:5432",
"connect";
// permission java.net.SocketPermission "*.noaa.gov:80", "connect";
// };
//
// The permissions granted to the context WEB-INF/classes directory
// grant codeBase
"file:${catalina.home}/webapps/examples/WEB-INF/classes/-" {
// };
//
// The permission granted to your JDBC driver
// grant codeBase
"jar:file:${catalina.home}/webapps/examples/WEB-INF/lib/driver.jar!/-" {
// permission java.net.SocketPermission "dbhost.mycompany.com:5432",
"connect";
// };
// The permission granted to the scrape taglib
// grant codeBase
"jar:file:${catalina.home}/webapps/examples/WEB-INF/lib/scrape.jar!/-" {
// permission java.net.SocketPermission "*.noaa.gov:80", "connect";
