Security exceptions.

[Sergey V. Udaltsov]

Hi all

I am running tomcat 3.2.2 with Apache 1.3.19 using JDK 1.3.1 by Sun.

The script /usr/bin/tomcat is called with "-security" parameter.

The file /var/tomcat/conf/tomcat.policy contains, among others, the
lines:

grant codeBase "file:/usr/local/idle/web/-" {
    permission java.security.AllPermission;
};

When I try to call some .jsp file which creates the bean from
/usr/local/idle/web/WEB-INF/lib/idlebase.jar,
I get the exception:

Error: 500

Location: /idle/common/jsp/courseList.jsp

Internal Servlet Error:

javax.servlet.ServletException: access denied (java.io.FilePermission
/usr/local/idle/web/WEB-INF/lib/idlebase.jar read)

The exception is caused by my class which is trying to read
(getResourceAsStream) some resource file existing in the same .jar.

Any ideas what's wrong here?

Sergey
