Re: JSP, sessions: how to notify bean about the session end?
Any examples or resources for this? William Brogden wrote: "Sergey V. Udaltsov" wrote: Hello all My JSPs uses some session-scoped bean.

AFAIK usual finalize can be called ages after the object is really free - so I do not like this way. Any ideas? Regards, Sergey Take a look at the HttpSessionBindingListener interface. If your Bean implements this class, you can get a notification when the session times out or is otherwise invalidate. -- Tony Keith - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Help on j_security_check -- not found
Hello all, I have seen your various posting regarding JDBCRealm, IMHO you seem to be an expert in this topic. I have configured my server.xml and web.xml properly to throw me to login.jsp page whenever I try to access a protected page. But the problem is that when I submit log in on jsp page it does not do anything, it shows me the login page again. And the httpd.log file shows me an error saying /var/tomcat/webapps/example/jsp/security/login/null not found my server.xml entries are as follows RequestInterceptor className="org.apache.tomcat.request.JDBCRealm" debug="99" driverName="com.sybase.jdbc.SybDriver" connectionURL="jdbc:sybase:Tds:/testdb" connectionName="test" connectionPassword="test01" userTable="t_user_profile" userNameCol="usernames" userCredCol="userpasswd" userRoleTable="t_roles" roleNameCol="roles" / The database is set up exactly as shown my web.xml has following entries security-constraint web-resource-collection web-resource-nameProtected Area/web-resource-name !-- Define the context-relative URL(s) to be protected -- url-pattern//jsp/security/protected//*/url-pattern url-pattern/secure/checkMerchant.cgi/url-pattern !-- If you list http methods, only those methods are protected -- http-methodDELETE/http-method http-methodGET/http-method http-methodPOST/http-method http-methodPUT/http-method /web-resource-collection auth-constraint !-- Anyone with one of the listed roles may access this area -- role-nameallok/role-name role-namereadonly/role-name /auth-constraint /security-constraint !-- Default login configuration uses BASIC authentication -- !-- login-config auth-methodBASIC/auth-method realm-nameExample Basic Authentication Area/realm-name /login-config -- !-- Form-based login is enabled by default.

Bean problem...
Hello,
I have a strange problem with beans.
I can run my bean just fine if it is in a package.
For example:
package foo;
public class testBean {
...
}
and it is located in a foo directory under classes directory:
/usr/local/src/jakarta-tomcat/webapps/myapps/WEB-INF/classes/foo
but if I remove the package from the class
public class testBean {
...
}
and move the class to the classes directory:
/usr/local/src/jakarta-tomcat/webapps/myapps/WEB-INF/classes
The bean gets produces the following errors:
org.apache.jasper.JasperException: Unable to compile class for
JSP/usr/local/src/jakarta-tomcat/work/localhost_8080%2Fmyapps/_0002fjsp_0002fforms_0002fsignup_0002ejspsignup_jsp_9.java:63:

initHandler = (testBean)
Beans.instantiate(this.getClass().getClassLoader(), "testBean");
This is on
RH7.0
apache
tomcat 3.2.1
mod_jk
Any ideas why the bean has to be in a package to work?
The /usr/local/src/jakarta-tomcat/webapps/myapps/WEB-INF/classes is in
the $CLASSPATH...
TIA

Is this a specification of JSP?

there is a need for a package to make a bean. the bean has always to be

otherwise the JSP cannot acces the bean

Apache/Tomcat port configuration
In tomcat/apache configuration...I have aliases, and mapping working fine. When calling upon the page with http://192.168.1.10:8080/mypath/script.cgi the servlet is executed properly and there is no problem. However the same address typed as http://192.168.1.10/mypath/script.cgi fails to work. Where do I need to change my configuration so that apache knows to send the page request to tomcat? Also, what is the configuration to enable SSL so that the above address could also be accessed via https? Does apache need to have a virtual host for this IP/host?

That should do it, but I have noticed serious
performance degradation in switching from JServ
1.1.2 to Tomcat 3.2b6. I am not sure if I am missing
something in the docs, but JServ 1.1.2/GNUJsp 1.0 is
IMHO much faster (at least with the mm.mysql JDBC
driver apps I have written) If someone could point
me to some tuning tips/parameters I may have missed
in the standard docs I would really appreciate it.
