MBean/Tomcat ClassNotFound
Hi, Im trying to deploy a Mbean in a web app. When I create the MBean, the next exception is throwed: javax.management.ReflectionException: null nested exception is java.lang.ClassNotFoundException: es.tid.puzzle.framework.jmx.agente.ControladorServicios java.lang.ClassNotFoundException: es.tid.puzzle.framework.jmx.agente.ControladorServicios at mx4j.server.DefaultClassLoaderRepository.loadClassFromRepository(DefaultClas sLoaderRepository.java:99) at mx4j.server.DefaultClassLoaderRepository.loadClassWithout(DefaultClassLoader Repository.java:33) at mx4j.server.DefaultClassLoaderRepository.loadClass(DefaultClassLoaderReposit ory.java:28) at mx4j.server.MX4JMBeanServer.createMBean(MX4JMBeanServer.java:697) at mx4j.server.MX4JMBeanServer.createMBean(MX4JMBeanServer.java:689) But the class is present. I tried to change the jar, putting it in shared/lib or in common/lib, pero its the same. The only solution is to put the jar into classpath definition in catalina.bat, but I prefer not to touch the tomcat classpath. ¿how can I do it? TIA José Luis

Re: tomcat JSP Servlet Apache JK2
It's a difference of path. To Apache, the ecommerce webapp is the root of your site, but Tomcat does not see it that way. Tomcat only recognizes the ROOT webapp as the document root. Rename the ecommerce webapp to ROOT (notice the all caps), deleting the original ROOT directory under webapps and reconfigure Apache to use that as the document root. The point is that URL paths in Tomcat and HTTPd must sync. Your login.jsp can't be /ecommerce/login.jsp in tomcat and /login.jsp in Apache. --David jeusdi wrote: Hello, mmm, I've compiled and linked and configured mod_jk with Apache 2.0 correctly, but I doesn't work correctly.

Initializing session in a Filter
Hi,
I have a filter (for /*) in which I'm caching something in the
session. Here is a piece of code:
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) {
HttpServletRequest req = (HttpServletRequest) request;
HttpSession session = req.getSession(false);
if (session == null) {
System.out.println(Create a new session: + new
java.util.Date());
session = req.getSession();
}
// cache something
}
The first time I make a request, since req.getSession(false) returns
null, a session is created by a call to req.getSession() manually.
The second time I make a request to the server, req.getSession(false)
returns null and so a session is created again.
In all other request (third, ...) the last created session (second) is returned!
My question is why session is created two times?
Thanks in advance.

Session hijacking with Tomcat/Myfaces - unable to fix it
The default Tomcat installation is prone to session hijacking. I would appreciate help how to fix it. The problem is that the session-id generated under HTTP (eg. for any JSF page) is caried over to authenticated confidential pages under HTTPS. Thus the session ID can be easily sniffed under HTTP, then misused after user logs-in under HTTPS. I believe it can be considered as a serious security bug. Scenario: 1) Tomcat and JSF, using Apache MyFaces. 2) A single application (context), using JSF pages 3) Some pages are public, and Faces servlet requests session ID on the first hit 4) Some pages are only accessible under HTTPS after authetication, as defined in web.xml: security-constraint web-resource-collection web-resource-nameSecret part/web-resource-name url-pattern/secret/*/url-pattern /web-resource-collection auth-constraint role-namesecret_role/role-name /auth-constraint user-data-constraint transport-guaranteeCONFIDENTIAL/transport-guarantee /user-data-constraint /security-constraint 5) Form-based authentication is used for the login (again, defined in web.xml). 6) The user goes to the public part of the aplication, gets a session ID (under HTTP) 7) The user goes to a confidential URL, logging-in successfully. The same session ID is retained!!! 8) Anyone who knows the session ID generated in step 6 can reach the confidential URL. We have not found any straightforward way of making Tomcat regenerate the session ID once user swichtes to HTTPS. We tried many approaches, and all of them break some part of the JSF application.

You can't place a jsp in /usr/local/tomcat/webapps. Tomcat does not make that location available to the client. You originally had a ecommerce webapp with a login.jsp file you wanted to access at the top level. I recommended you rename the webapp 'ecommerce' to 'ROOT' and reconfigure apache httpd to use that as the docroot instead of 'ecommerce'.

Re: Session sharing accros subdomains?
hy , I think that your problem is on the client side. session is maintained through cookies (well you know what i mean server discriminates session based on cookies and stores data somowhere on server) and your client will never send cookie to different server (in some cases maybe it will work but mostly not). So if you want to do this you first have to deal with this problem than you could serialize whole session data and store it somewhere in database and on new domain you can deserialize it and use it as session regards On 8/9/06, Madhur K Tanwani [EMAIL PROTECTED] wrote: I've a main website hosting domain domain.com.

Re: tomcat JSP Servlet Apache JK2
There are a lot of issues here, mostly having to do with how you've structured your virtual hosts. However, I think the following should get you up and running quickly. In your VirtualHost directive, add the following line: DirectoryIndex index.html index.html.var login.jsp That should bring up the login.jsp as a default index when someone just goes to the directory. Note, I have not tried this, but I do use this to serve up .pl and .php index files. I normally don't have a login.jsp page as the entry point into my web application. I normally put an index.html splash page with a note about the web application, and then on that page provide a link to the login page should the user want to log in. As I said above, there are a lot of potential issues with the way you've constructed virtual hosts, both with Apache and Tomcat. The Tomcat issues are certainly on topic for this mailing list, but the Apache issues are probably not.

IfModule mpm_worker_module StartServers 5 MaxClients 448 MinSpareThreads 5 MaxSpareThreads 25 ThreadsPerChild 7 MaxRequestsPerChild 0 /IfModule Interesting, very few ThreadsPerChild. Not really a problem, but I wonder if this is efficient. We have decresed this value because we thought that maybe Apache is opening too many threads to Tomcat. We had in Tomcat's log entries saying All threads (500) are curently busy, increase maxThreds. Threads in Tomcat = Sum of numbers of apache threads used during peak times. So this relates more to MaxClients and not to ThreadsPerChild. If you want to connect many Apaches with a lot of threads to tomcat you need to use tricks like the APR connector on the tomcat side. A few hundred threads should be no problem, on a good OS even 1.000-2.000 should work. Think about using connect_timeout and prepost_timeout. Maybe also set recovery_options to 3. What values do you suggest for above parameters ? connect_timeout=2 This is in Milliseconds. Anything between 2000 and 2 should be OK. The right value depends on your trust in latency, reliability of your network and the responsiveness of the target machine. prepost_timeout=1 Values between 5000 and 3 are reasonable. Arguments the same as before. recovery_options=3 or 7 (here you'll need to experimnt on your own. The added 4 is very new, but maybe helpful).

If the request matches mod_jk JkMount config, it should try to send to tomcat and the result would be some 50X?

I did, but then I get more than I get one object created for each application.

Re: Modifying saved URL from j_security_check
Hi Mark,
something really, really strange is happening here: As you suggested, I've
subclassed org.apache.catalina.authenticator.FormAuthenticator, patched the
Authenticators.properties in catalina.jar, however, my own Authenticator is
not being used.
Strange though, since if I delete my jar where my Authenticator resides from
server/lib, Tomcat won't start up grumping that my class is missing...
I've overwritten the methods invoke(), where I'm just throwing an Exception
(to make sure that my class is really triggered as a 1st try), also I've
overwritten the method restoreRequest() and authenticate() - none of the
methods gets hit.
Do you have any idea what I'm missing here?
Below is my code (short simple):
[cut]===
package com.cr.manuals.catalina;
import java.io.IOException;
import java.util.Iterator;
import java.util.Locale;
import javax.servlet.ServletException;
import javax.servlet.http.Cookie;
import org.apache.catalina.HttpRequest;
import org.apache.catalina.HttpResponse;
import org.apache.catalina.Request;
import org.apache.catalina.Response;
import org.apache.catalina.Session;
import org.apache.catalina.ValveContext;
import org.apache.catalina.authenticator.Constants;

org.apache.catalina.authenticator.FormAuthenticator {
/**

*/
public void invoke(Request request, Response response,
ValveContext context)
throws IOException, ServletException {
System.out.println( inside own invoke );
throw new ServletException(Inside invoke);
}
/**

*/
public boolean authenticate(HttpRequest request,
HttpResponse response,
LoginConfig config)
throws IOException {
System.out.println (*** inside own authenticate );
return super.authenticate(request, response, config);
}
/**
* Restore the original request from information stored in our session.
* If the original request is no longer present (because the session
* timed out), return codefalse/code; otherwise, return
* codetrue/code.
*
* @param request The request to be restored
* @param session The session containing the saved information
*/
protected boolean restoreRequest(HttpRequest request, Session session) {
System.out.println(* inside own restore *);
return super.restoreRequest(request, session);
}
}
[cut]===
This is the content of my Authenticators.properties:
[cut]===
BASIC=org.apache.catalina.authenticator.BasicAuthenticator
CLIENT-CERT=org.apache.catalina.authenticator.SSLAuthenticator
DIGEST=org.apache.catalina.authenticator.DigestAuthenticator
FORM=com.cr.manuals.catalina.FormAuthenticator
NONE=org.apache.catalina.authenticator.NonLoginAuthenticator
[cut]===
I thought that maybe the reason for this might be that we're running in
SSL-mode, however, same behaviour when using pure http
FYI: Tomcat 5.0.28, Suse Linux 9.1
Clueless...

Dynamically Determining the Web App
Dear Friends, I have two web apps that are identical except for their root directory (and context entry in server.xml). Is there any way of determining from within a servlet which one is actually running? Or, alternatively, is there a way of retrieving values from the context section of server.xml for the corresponding web app? Thank you very much! - Robert Kohn

Re: Session hijacking with Tomcat/Myfaces - unable to fix it
It's a fundamentally bad security scheme to use the session-ID as the identifier for your users. Might be straight forward, but architecturally a bad choice if you *really* want a secure area. Kim :-) On 8/9/06, Tomas Hulek [EMAIL PROTECTED] wrote: The default Tomcat installation is prone to session hijacking. I would appreciate help how to fix it. The problem is that the session-id generated under HTTP (eg. for any JSF page) is caried over to authenticated confidential pages under HTTPS. Thus the session ID can be easily sniffed under HTTP, then misused after user logs-in under HTTPS. I believe it can be considered as a serious security bug. Scenario: 1) Tomcat and JSF, using Apache MyFaces. 2) A single application (context), using JSF pages 3) Some pages are public, and Faces servlet requests session ID on the first hit 4) Some pages are only accessible under HTTPS after authetication, as defined in web.xml: security-constraint web-resource-collection web-resource-nameSecret part/web-resource-name url-pattern/secret/*/url-pattern /web-resource-collection auth-constraint role-namesecret_role/role-name /auth-constraint user-data-constraint transport-guaranteeCONFIDENTIAL/transport-guarantee /user-data-constraint /security-constraint 5) Form-based authentication is used for the login (again, defined in web.xml). 6) The user goes to the public part of the aplication, gets a session ID (under HTTP) 7) The user goes to a confidential URL, logging-in successfully. The same session ID is retained!!! 8) Anyone who knows the session ID generated in step 6 can reach the confidential URL. We have not found any straightforward way of making Tomcat regenerate the session ID once user swichtes to HTTPS. We tried many approaches, and all of them break some part of the JSF application.

JDBCRealm with Simple Servlet Filter
Hello, I have configured a SimpleServletFilter to act as my authentication filter, i want it to do certain things after the authentication has failed. My application is being authenticated using a TOMCAT JDBC Realm. The authentication scheme is BASIC. I noticed that the filter is being called after the authentication is done, that is only if it is a valid user the filter is being called. The filter is not called at all in case the authentication has failed. Any ideas on this problem will be much appreciated. Thanks Dhiraj Ramakrishnan

Re: getRealPath and war file
Hello Romain, Is there no way you can use the temporary working directory (javax.servlet.context.tempdir)? I don't know what pushing inside a client browser means, but as you mentioned the files are temporary, this sounds like the place to put them.. Also, you won't need to worry about maintaining some extra directory after deployment, and this is a portable solution.
