how to check if user is authenticated
I am doing form based login using JDBCRealm and for logging out I call request.getSession().invalidate(). The problem is that after invalidation (duering the very same request) I can still use request.getRemoteUser() and it returns user name just like before calling session.invalidate(). What would be the proper way of asking if the user is logged in or not? I cannot set any session attributes duering login process since I am using tomcat's built in JDBCRealm authentication. Oh and I am using latest nightly build of Tomcat 4.0. Thank you so much for your time with best wishes, Taavi
Help with Tomcat4
Hi, I'm using experimenting with Tomcat4 and I did the following:- I wrote a servlet that implements the ContainerServlet[Obviosuly in the org.apache.catalina.servlets package] . Now I have a set of JSPs which in turn use a set of Java beans whcih in turn use this Servlet for getting hol of information on Context etc. However I am facing the follwing problem:- In my Java bean if I import org.apache.catalina.Deployer it's not able to find the class in my classpath and throws a ClassNotFoundException. I found this problem very weird as these are the classes in the standard JAR that comes with Tomcat 4. Could someone please explain this to me? Anand Associate,RD, Digital Think

rollback problems in session facade
Hello, I am using a SessionBean as a Facade to my EntiyBeans! Well, in one of my SessionBeans I have implemented a method which creates some EntityBeans. Thats all ok, however after that creation I also call some additional set-methods on these creates EntityBeans. If one of these method calls fails an exception is thrown and the transaction is rollbacked. Howerever, the created EntityBeans in that transaction context are still available that means the corresponding entries in my database are still there and were not rollbacked. Is that behavior correct or do I do anything wrong, so that I have to remove all created EntityBeans on myself in the catch-clause of my try-catch block?? Thank you Daniel Schaller

Installation of tomcat package on a debian woody system
I'am trying to get tomcat to work on a Debian woody system, but the only success I have is a plain/text file from local- host. First of all I compiled the sources from jakarta.apache.org, but it stucks due to a segmentation fault. Anyway. Then I tried to install all required packages and changed the init scripts so they can find $DAMON and $CONFIG files: ( the values were set to my self compiled system ) Tomcat 3.2.2-1 apache 1.3.19-1 jdk1.1 1.1.8v1-3 libapache-mod-jk 3.2.2-1 I started apache with /etc/init.d/apache start. Now I'am trying to get access to localhost in order to execute my Hello.java script located under: /usr/share/java/webapps/ The content of this script is available in my browser in plain/ ascii, so I expect the Mime-Types aren't recognized from tomcat ? Before that I've changed server.xml so tomcat can reference the document and proofed that the following lines are included in the httpd.conf: IfModule mod_jk.c The following line is for apacheconfig - DO NOT REMOVE! JkWorkersFile /etc/apache/mod_jk/workers.properties Include /etc/apache/mod_jk/tomcat-auto /IfModule So the module seems to be loaded as without the IfModule directive no error message appears. The bugzilla at debian.org has no entries included refering to tomcat and I wrote a mail to debian-user without any answer to my question. Has someone possibly the a/m packages installed and was able to get them to work properly ? -- Best Regards, Mark

Re: Memory used by java process
As long as the growing process stops at some point it's fine. Java is dynamic by nature, meaning the classes are loaded on demand, not proactively. Jsp pages are compiled into servlets and get loaded only as needed, that's why process size is growing with time. Try -verbose options to see how many classes get loaded per request. You're also generating objects yourself in servlets/Jsp's. Some of them are long lived, which contributes to growing heap/process size. Another thing is that VM doesn't give all memory back even after it's reclaimed by GC. If it keeps growing without bounds most likely you have a memory leak somewhere, meaning some objects cannot be reclaimed by GC because they are strongly reachable. Also, the -Xincgc option you use enables train or incremental garbage collection, which from my experience makes GC less aggressive in general (this is what it's meant for anyway), which translates into larger Java process/heap size but less noticeable GC pauses.

If the bean classes must also be referenced from within your webapp, you can put them unde $CATALINA_HOME/common/classes or $CATALINA_HOME/common/lib to make them available both internally and externally. It goes without saying that using this facility is very much specific to Tomcat 4, and you should be very security conscious in your programming -- since the Container servlet has complete access to Catalina internals. But the technique is definitely useful for building Tomcat 4 administrative tools as web applications. Anand Associate,RD, Digital Think Craig McClanahan

Re: Using Normal Html in methods, or class structures in JSP
Your example below creates a syntactically invalid page -- if you use the
%! ... % construct to declare a method, the *entire* method declaration
needs to be inside the same construct.
You should really really really be using servlets for stuff like this --
trying to mix code and HTML output on the same JSP page is just going to
get you into trouble.

RE: how to make a servlet as the home page
Ok, if you're using apache, then the first thing apache does when it gets a request for a directory is look for the DirectoryIndex instruction. typically this will be set to index.html index.htm index.jsp etc. The way this works is that apache will first check index.html, then index.htm, then index.jsp and serve whichever comes first. the second part of the equation is the JkMount directives. Say you create a directive JkMount /MyHomePageServlet ajp13 then you can set DirectoryIndex MyHomePageServlet index.html index.htm index.jsp and afaik apache should route the request for / to tomcat, and tomcat will know how to serve /MyHomePageServlet. just a warning this is all theory, I haven't tested it, but I think the concepts are right. hth, cheesr dim - Original Message - From: naveen [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Sunday, August 26, 2001 9:29 PM Subject: how to make a servlet as the home page hi , I am using tomcat and apache, I want to make a servlet as the home page of my web site, when i access http://www.mysite.com/, a servlet needs to be called and the most important thing in this is I need to access HTTP variables like Remote Host, etc. thanks in advance

Virtual hosting
How can I do virtual hosting in tomcat. Do I have to make change in server.xml only or do I have to make any other change in apache or tomcat folder. Please let me know if anyone has done it successfully. __ Do You Yahoo!? Make international calls for as low as $.04/minute with Yahoo! Messenger http://phonecard.yahoo.com/
Re: OutOfMemory - Set Java Heap Size?
Many thanks, Craig, Aravind and Shaun, for your comments. They are most appreciated. I set the TOMCAT_OPTS to -server -Xms64m -Xmx192m as you suggested Shaun... I wasn't aware of the HotSpot application, I'm now reading up in it. Thanks for the tip. Unfortunately, I still cannot launch a 7th Tomcat process, and I don't understand why not. I feel I'm missing something, but I just can't figure it out. 6 works, but adding a seventh raises the OutOfMemoryError. It does appear from the console output that Tomcat fails when it tries to start a PoolTCPConnector. I start two connectors for each application (ie, Tomcat process), one is an Ajp13ConnectionHandler, the second an Ajp12ConnectionHandler which I understand is required for Tomcat to be closed down. I've included one of my server.xml files below, just in case there is a glaring error in there. There's an xml for each application, they are all the same except for the different ports I've assigned, and the log and work file names etc. Any further suggestions would be most appreciated, I'm have a minor heart attack at thought of having to buy one server for every 6 small jsp applications I want to run!
