Re: Refuse connections in the selector
Yes, I want to write my own NIO code. But I dont know how to cancel/close a connection in the selector, because the file NioEndPoint.java es so confusing and I dont in which of class of that file I have to do that. Tnaks I'm still not sure what you're asking, but if you are writing your own NIO code, then you can cancel/close a connection that is in the selector pool at any point in time. Just get it out of the selector pool, and close it. Filip ubekhet wrote: Hi Filip, Is related java nio, and in this case as I use Tomcat with NIO paradigm, is the same.

I still havnt found a reason to really use JMX in my own servlets... because its TC. In an accounting app or something like that, I think JMX would be great. Anyway... thats why I think documentation is a little thin in this area. If you are into the source... then this whole registration thing will be done differently... but for that, you'll have to ask the guy the wrote it. ie if you playing with the TC source in org/apache/catalina/mbeans For that you have to be younger than 20... else you may run out of time ;) Hi Caldarale, Yes, I use the current version of Tomcat. Thanks for your link, but I want to know how to implement MBean, because according the web you gave, I have to add my MBean to the mbeans-descriptor.xml and also the folder where is contained. For example, if I want to implement the HelloWorld in java/org/apache/catalina/mbeans, first of all I have to add to mbeans-descriptor.xml in java/org/apache/catalina and then also in java/org/apache/catalina/mbeans. On the other hand, I've implemented HelloWorld.java in java/org/apache/catalina/deploy and HelloWorldMBean as interface in java/org/apache/catalina/mbeans. This implementation is the correct way? Other way in the same java/org/apache/catalina/deploy directory contain another mbeans-descriptor.xml file Can you say me, if I am right? Thanks a lots!!!

Multiple authentication schemes within a webapp
Hi, I have a webapp that uses form based authentication but I'd like to also be able to login to it using basic authentication. The main use case for this is to present a nice form based login for web users, not involving the standard browser's username/password prompt, but also allow people to include their username and password into the url for use in the likes of wget and other tools. Can anyone give me recommendations on how to achieve this? As far as I can tell I can't have more than one login-config elements in the web.xml. Would I need to implement a new Authenticator delegating to BasicAuthenticator and FormAuthenticator?

problem about tomcat session management

Sorry, but the common programmer ought to know that, in spite of SQL's
standard-ness, every RDBMS implementation is slightly different. Just
try to do something as simple as getting the database to generate a
unique id for you, and suddenly you are outside of the standard.

You probably mean something like SQL-92. Or maybe SQL3? FIPS
127-1/SQL-89? The problem is that SQL is not as standard as you think.
Sure, some group of people sat in a room and made some decisions, but
the database companies also made different decisions.
| AFAIK DB2 doesn't know the binary attribute, not sure about Oracle,
| Postgres, Informix etc.
No, they have other ways of doing this. See
http://www.orafaq.com/node/999 for instance. SQL Server has the same
semantics as MySQL ('=' is case-insensitive). It's all over the map.
Remember that JDBC is a method-oriented API, but does not make any
assumptions about the underlying implementation. You are free to call
(SQL) functions that only exist in certain databases and not in others.
Want string concatenation in Oracle? Use ||. Moving to another database?
Well, you're gonna have to change all those to something else (usually a
function call).
There are many many many examples of this.

Absolutely. This is the name of the game when using RDBMSs. Sorry to

On our projects, we don't use Tomcat realms, but we definitely see the
case-insensitivity of usernames as positive behavior, since we tend to
use email addresses as usernames. Email addresses are, by definition,
not case sensitive, so making usernames match those semantics is good
for us.

Serializable classes distributed with the JRE have explicit serialVersionUID values, and are changed whenever the class implementation changes - not just when methods or fields are updated.

RE: Tomcat 5.5.26+sun jdk1.5.0.15 linux for 64 bit architecture problems
From: Niki Diulgerov [mailto:[EMAIL PROTECTED] Subject: Tomcat 5.5.26+sun jdk1.5.0.15 linux for 64 bit architecture problems CATALINA_OPTS=-Dlogs.root=/opt/logs -Dwas.install.root=/opt Those system properties are not used by Tomcat; are they for a webapp you've deployed? JAVA_HOME=/jdk1.5.0_15/jre Your JAVA_HOME setting is wrong - it should be just /jdk1.5.0_15 (although that's an unusual place to install the JDK - it's typically in something like /usr/local/jdkversion). Are you sure you're using the desired JDK? Have you set the PATH properly? What does java -version display? Are these examples supposed to work with 5.5 tomcat and the version of sun java which I'm using? Yes. Is this connected with the x64 architecture which I have. Probably not, if the JDK is properly installed. Can it be something with the fact that on the java sun build which I downloaded it is written amd64 and my CPU is Intel? No, the AMD64 architecture is what market pressure forced Intel to implement for its EM64T chips (now known as Intel 64, just to provoke confusion with the despised IA-64). It's also known as x86-64, which is what AMD originally called it. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Deploying Servlets in users directory
Hello all, I'm using tomcat 6.016 and have configured userconfig in server.xml to look in user's public_html subdir for jsps etc. Jsp files works fine in user directories but servlets do not. Does anyone have tomcat working with servlets in user's public_html subdirectories?

Re: JMX MBean
Chuck's post works for implementing custom Tomcat components (e.g. a custom Realm extending RealmBase). If you are implementing a custom class that doesn't extend any Tomcat class, then your class will have to self-register itself. Since you say you are using TC6, the default configuration should give you access to the Registry class to allow you to do it using the mbeans-descriptor.xml method that the (forked) commons-modeler uses. ubekhet [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi Caldarale, Yes, I use the current version of Tomcat. Thanks for your link, but I want to know how to implement MBean, because according the web you gave, I have to add my MBean to the mbeans-descriptor.xml and also the folder where is contained. For example, if I want to implement the HelloWorld in java/org/apache/catalina/mbeans, first of all I have to add to mbeans-descriptor.xml in java/org/apache/catalina and then also in java/org/apache/catalina/mbeans. On the other hand, I've implemented HelloWorld.java in java/org/apache/catalina/deploy and HelloWorldMBean as interface in java/org/apache/catalina/mbeans. This implementation is the correct way?

question about protected resources in a security-constraint and login-config
I am using tomcat 5.5.23 to set up form based authentication. I have looked at the source code and ran the security/protected example that is provided with tomcat, and I have a question about the resources associated with the login-config. The two jsps defined in the login-config are in the security/protected directory, under which I thought all resources are protected. How is it then these two pages can be displayed without the user logging in? Or is there an exemption for those pages defined in the login-config? [The reason I am asking is that I am trying to work out the best structure for my application. I want my login pages to contain images and css and those resources *will* have to be in an unprotected area. When I created a protected directory then I had all sorts of trouble with the path to the unprotected resources. My current structure is: /login.jsp /error.jsp /images/*.gif /application.css /protected/*.jsp /protected/images/*.gif but when I try to access protected/*.jsp tomcat brings up the correct login page but seems to think that all resources that are relatively defined in login.jsp are actually relative to the protected area. The only way I can fix this is to define absolute paths in my jsp, a solution which I am not particularly happy with (I saw an associated posting on this for a different version of tomcat: http://mail-archives.apache.org/mod_mbox/tomcat-users/200311.mbox/[EMAIL PROTECTED])] Any help with the original question would be much appreciated.
