RE: web.xml layout
I believe that the web.xml is parsed using the DTD, so rearranging the elements will make it complain that the format of the file is incorrect. Even if you find a container which lets you rearrange, the spec says you should follow the DTD. So to be portable . . . .

RE: Wierd Casting Problem. Tomocat Bug?
Are any of the classes you are using defined outside of the web app. That
is, are you using any libraries, or class files which you specify on the
classpath prior to tomcat starting, which may also be in your web-app. It
is situations like this which the more experienced folks point to as the
cause to this problem. Generally, the type of error you are mentioning
happen if the class is loaded by a higher level class loader than the
JSP/Servlet's loader, but the JSP/Servlet sees the web-app's WEB-INF class
and libs before the system's classes and libs. So if the object was created
by the system class loader (with it's copy of the class), it has a different
'Class ID' than one loaded by the JSP/Servlet class loader.
In short, try to remove all elements from your class path and extentions
directories, and put them all in the webapp for a short testing period. See
if this exposes solves the error or exposes a place where some code would
get a class from a different class loader than from others. Then you can
slowly move the libraries back where they came from to better isolate your
problem.
Hope that helps,
Paul

I found out the problem. This looks like an extreme hack though.
$=((member) ((Object)e.nextElement()) ).getFname()%
Works. But why do I have to cast to an Object before I cast it back to
it's appropiate type. My only guess is that the Servlet DownCast the
Vector to an Object (because there is some reflection that goes on) before
setting the Attribute and passing it to JSP.
But the actual member objects are put in the Vector as member Objects.
Any Ideas? Does anyone thing it's wierd that you have to cast to and Object
then to the Type.
I believe this isn't a Java Bug it may be a Tomcat Bug. Because I don't
have to cast to an Object, if I am casting to member objects in the Servlet.

Subject: Wierd Casting Problem.
Ok. Here is the problem. I am using Model 2 Architecture. So my Servlet
handles all the biz logic and pushes the results that are then displayed by
jsp pages.
Within a jsp page I grab my vector from the request like so..
Vector mems =(Vector)request.getAttribute(response);
Then I try to loop around it and cast it to the appropiate
Object. Like
so...
%
for (int i=0; i mems.size(); i++) {
member m = (member)mems.get(i);
%
%=m.getFname()%
%}%
I get a ClassCastException. But when I do a toString on the Object
itself without casting, it specifies the package name of the object that I
am trying to cast to.
To make matters wierder. When I do a getClass().isInstance(THE OBJECT
I
WANT TO CAST TO) it returns false?
What is going on here? Is this some classLoader issue?
Some tips that might help figure this issue out..
I am importing the class I am casting, in the JSP page. like
so..
%@page import=thepackage.member, java.util.*%
And the class itself isn't in a jar. It's in the
WEB-INF/classes
directory.
I also changed the container from a Vector to an ArrayList and
got the
same results.
And I can instantiate the member object itself and use it in
the jsp
page.
Any ideas? Please. Someone, HELP!!!

The requests are load balanced between the 2 servers and session stickyness works fine (once the session is established the request is always routed to the right app server based on the suffix in the jsessionid). But when the cookies are disabled (I am encoding encoding the url) the requests are distributed between server1 and server2 meaning doesn't stick to the same app server. When there is a request from the browser (and the URL has the jsessionid.suffix) the mod_jserv doesn't route it to the right app server based on the suffix in the jsessionid and the session is lost (a new session id is created). Wouldn't you necessarily have to have cookies enabled to get this to work since http is a stateless protocol? I mean, what your asking the protocol to do is something it can't do without cookies, or something that it can use to record session information.
RE: URGENT - Session stickyness lost with cookies disabled
They are exclusive. Basically, for every link back into the web application that needs to maintain session, the programmer must call and EncodeURL function so that tomcat can add the JSESSIONID parameter to the URL at execution time. Apache URL rewriting allows the server to 'adjust' the incoming URL so that it goes somewhere else. -Original Message- From: Tim O'Neil [mailto:[EMAIL PROTECTED]] Sent: Friday, April 13, 2001 4:44 PM To: [EMAIL PROTECTED] Subject: RE: URGENT - Session stickyness lost with cookies disabled At 04:18 PM 4/13/2001 -0400, "CPC Livelink" wrote: Tomcat does support url rewriting, but the developer must have written the web app to support it - otherwise no dice.

RE: Session timeouts
You could track the ValueBound event, and at binding time, make local
references to the session objects you are interested in. Then when you are
unbound, you do not need to worry about the order, since you have a local
reference and can still get/change information on it.

Subject: RE: Session timeouts
Yep, I do implement HttpSessionBindingListener and no I can't call
invalidate because I depend on other objects bound to the session within my
session tracker and invalidate does not define the order at which it will
unbind objects. Therefore I need to do an explicit removeAttribute call so
that I am assured the rest of the objects I need are still within the
session.
For reference here is my code
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
import edu.vt.ward.lexus.portal.User.*;
public class SessionTracker implements HttpSessionBindingListener{
private String userPid;
private ServletContext context;
private Hashtable currentSessions;
public SessionTracker (ServletContext ctx){
context = ctx;
}
public void valueBound(HttpSessionBindingEvent event) {
HttpSession session = event.getSession();
User user = (User) session.getAttribute("user");
userPid = user.getPid();
String totalLogins;
if(context.getAttribute("currentSessions") == null){
currentSessions = new Hashtable();
Date uptime = new Date(System.currentTimeMillis());
context.setAttribute("uptime", uptime);
totalLogins = "0";
}else{
currentSessions = (Hashtable)
context.getAttribute("currentSessions");
totalLogins = (String)
context.getAttribute("totalLogins");
}
Date creationTime = new Date(session.getCreationTime());
currentSessions.put(userPid, creationTime);
context.setAttribute("currentSessions", currentSessions);
int logins = Integer.parseInt(totalLogins) + 1;
totalLogins = Integer.toString(logins);
context.setAttribute("totalLogins", totalLogins);
}
public void valueUnbound(HttpSessionBindingEvent event) {
HttpSession session = event.getSession();
User user = (User) session.getAttribute("user");
userPid = user.getPid();

context.setAttribute("currentSessions", currentSessions);
}
}

Chad,
I am doing something very similar...
Are you implementing the HttpSessionBindingListener interface in your
object? If not, try implementing this interface in your object that is
placed in the session. This will throw a 'valueBound' event when the
object
is placed in the session and a 'valueUnbound' event when removed (either
explicitly or by timeout). The valueBound method will increment the count,
and the valueUnbound method will decrement it. Works perfectly for me.
Also, you might want to use session.invalidate() rather than explicitly
removing the session objects-- I found it was easier to manage.

Subject: Session timeouts
I have been experiencing some problems with sessions timeouts.
It
seems that they are not unbinding all my sessions attributes. For
instance. I have a session tracker object that gets bound to a user's
session when they log in. This simply adds 1 to an application level
attribute indicating the number of people who are currently logged
in. When the user's logs out I call session.removeAttribute("tracker");
explicitly and the attribute is unbound. This decrements the application
attribute by 1. This all works fine. However if the session actually
time's out the tracker object doesn't seem to be unbound. I.e. my little
session tracker program still show the user as loged in.
Has anyone else encountered this problem, and if so is there a
solution for it?

RE: static reference to a method
The problem is that you have not declared the method as static. So you need
to either do this :
(new dynamicContent.dynamicContent()).getSelected("A", "B");
or declare the function as static String getSelected(string a, String b) and
call
dynamicContent.dynamicContent.getSelected("A", "B");
If the function is not declared static, then you have to have an object of
the class to call the function.

Subject: static reference to a method
Hi there
I was wondering if anybody could help me out with
something?
I have a JSP that is trying to access a method in a
java class that I have defined. However, when I try
and run the pgae, it gives the 500 error message and
says
"Can't make static reference to method
java.lang.String getSelected(java.lang.String,
java.lang.String) in class
dynamicContent.dynamicContent."
I have not declared the method as static nor the
class.
The method is part of an error handling page (called
retry.jsp) that is shown to the user when they have
entered data incorrectly in a form. Its function is to
preselect an option (by returing the word SELECTED) in
a HTML select box (the one that the user entered in
the first place) by comparing the value that was
entered by the user in the original input form to the
value of the select box options as they are created
(they are dynamically created, not HTML coded).

RE: Closing ResultSet and Statement?
ResultSets can and should be closed. They are not like normal classes with
an iterator.
ResultSets are created by Statements. Statements can and should be closed.
When a statement is reused, it will close the resultset (if not closed
already) that it previously supplied in order to get the new results. When a
statement is closed it will close the resultset it created. The number of
simultaneous open statements for a given connection can be (and is)
limited - the oracle limit is about 50 by default.
Statements are created by Connections. If you close the connection it closes
the statement which closes the resultset.

Paul

RE: RequestDispatcher.forward() in Tomcat 3.2.1
What Craig meant (I believe) by "prohibits you from modifying the response" is that the response has been committed and no more data can be sent. The html/other-data you are sending to the client is part of the response. When the forward returns, you are prohibited by the spec, from adding any more information to the response output stream. If you need to do as you desire, you must use some kind of include based scheme instead of forward.

One reason you could get a "short read" response is if the servlet
container has already read the input stream's
contents. For example, if you are processing a POST
request and you have already called something like
request.getParameter(), the contents of the input stream would have
already been processed.

RE: Using a servlet superclass
Yes.
Have your WorkerServlets implement a procedure called childInit or
something, which is basically an empty procedure in the SuperServlet. Then
call this function as the last (or first) call of the SuperServlet init
function. This is much like how GenericServlet makes init() a convenience
call instead of init(ServletConfig config).

Subject: Using a servlet superclass
I have a number of servlets in my application that need to
perform common initialisation, etc. So I was thinking of
creating a superclass that has an init method that does all
of the common work, eg.,
public class SuperServlet extends HttpServlet {
public void init() {
// do common initialisation stuff in here
} // init
} // SuperServlet
Then all the workers servlets would extend SuperServlet
rather than HttpServlet, eg.,
public class WorkerServlet extends SuperServlet {
...
} // WorkerServlet
This seems to be OK, until I implement init in the
WorkerServlet, as the init method in the SuperServlet
does not then get invoked. While I can call super.init()
in the WorkServlet, I want this to be handled automatically
as I can bet on someone forgetting this step, eg.,
public class WorkerServlet extends SuperServlet {
public void init() {
// don't want to have to make this call == super.init();
} // init
...
} // WorkerServlet
Is there any way to implement this ?

Your explanation of using html:link and rewriting within a session is exactly what I'm doing (or trying to do). I also put in some defensive code to determine if the user messed with the URL or created a new browser with the same URL. I put code in my Form bean's reset method to double check that the request that is coming in actually applies to the object the user was last working on.

RE: Speeding up database accesses
While there are connection pools (I have not used them but others on the list can point you to them), I find the easiest solution is a session variable. Then make a function you can call with the session and db connection info. The function checks the session for the DB varaible. If it's not there it creates the connection and adds it to the session. Then returns the DB. That way the call to get the connection looks nice and clean (no nasty if statements to cloud up your HTML on the JSP).

RE: log files in tomcat
Actually, these are files that are generated by the jk_nt_service helper application, not entries in tomcat. If you want to capture the output of tomcat, you need to either a) redirect the output to a file (on Unix you also need to redirect stderr, on Windows stdout and stderr are much the same (I think)) or b) programatically change the stream pointed to by System.out and .err to something else which you have opened. -Original Message- From: Jason Pell [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 31, 2001 8:09 PM To: [EMAIL PROTECTED] Subject: Re: log files in tomcat I have also had problems with this.

RE: TOMCAT3.2 BUG
Not having tried this since I don't use JBoss, here is my thought. The only difference between putting it in the main tomcat classpath and putting it in WEB-INF/lib is the class loader that is used (javas versus tomcats). Since I have quite successfully used tomcats in WEB-INF/lib, I am guessing that maybe there is something a little but different about the jar file. Maybe you should try to unjar the package, and then rejar it yourself using no compression and no fancy options (or just leave it unjarred in the WEB-INF/classes).

RE: Problems with context-relative path include directive
The way it nehaves is that "/" is the root of your webapp. So, when doing things with the servlet container alone, you would reference the file as "/JSPHeader.jsp". If, however, you are sending something to the browser for it to get, then do "%= request.getContextPath() %/JSPHeader.gif" Somewhat weird, but it does make navigation from the root of your webapp easier since the name (context path) of the webapp can be changed.

RE: properties files and tomcat
Actually, there are good reasons to NOT do it that way. You may not have
access to the file system for one, or the property file may be embedded ina
JAR file. Whereas if you use the getResourceAsStream you don't have thise
problems. However, if you need to access an arbitrary file, using
FileInputStream is the way to go. For general purpose properties file usage,
I reccommend you stay with getResourceAsStream. It makes it easy to switch
the properties files you use by just changing the classpath a little bit.
And it allows you to have defaults buried deep in the class path which are
overridden by the same named resource which occurs earlier in the classpath.
Just my 2 cents.

Paul

RE: Running Tomcat as non-root user
You may be able to write yourself some native code to do the switcheroo for you. Then use the java calls to the native call.

I was afraid of that. 'ifconfig' is the utility that lets you see information about the network interfaces, not a firewall. :) Do you run multiple machines with a firewall in front of them to do the redirection (w/ load balancing for example) or do you run the firewall on each machine individually? I asked our operations people about the same thing being done in our load balancer (F5/BigIP) - but apparently it can't be done there.

How many applications do this (Apache for example) is to initially run as root, bind to port 80, and then drop root privileges. Is something like this possible with Tomcat running standalone?

I think the idea is that Webapps are distinct self-contained applications and therefore should not depend on _anything_ outside of the webapp. If you have components which need to share session info, they _should_ be in the same webapp. You would then build your webapp as you would any application that has multiple components and possibly multiple developers (very carefully ;) Regards, Paul -Original Message- From: Andy Nuss [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 13, 2000 09:19 PM To: '[EMAIL PROTECTED]' Subject: webapps are useless toys?!

RE: scope of a bean
If you use response.sendRedirect then you are telling the browser (ie client) to open the supplied URL. The browser then makes a new request for that URL. So, if your bean is scoped to a request, then it will be out of scope for the redirect. If it is scoped for the session or application, then it will still be there. On the other hand, if you do a forward operation (pageContext.forward) or an include, then tomcat handles it all internally, and so it is all one 'request', so a bean scoped as request will be seen by all the pages included or forwarded to.

RE: posting to servlets from a url
Well, then I think your next best bet is in the Tomcat 4.0 release which has the new Filter and Valve features. My only knowledge of these is from one of Craig McLanahan's posts, but if you check the spec, it will probably describe them in detail. My understanding, is that these would allow you to do exactly what you want - however, I don't know if you can wait that long or if you are able to use the 4.0 milestone builds in your environment. I think your next best bet is to disable the /servlet/ auto-mapping (I believe this is a tomcat extention) which should prohibit access to the stuff in WEB-INF/classes and lib (but sill allows access to all JSPs). Then have all access to your servlets be through inclusion or direct execution. I am not sure of the rules for direct executition so you may want to refer to the spec to see if that is allowed.

By the way, just to keep things as simple as possible, Apache, Tomcat

RE: non-cookie session tracking?
That's the problem with not using cookies. Since (in most cases) you will be using tomcat in conjunction with some other web server (tomcats limited web server is not sufficient for heavy use), the web server will directly serve your static pages - tomcat will never see them. If you need to track a session across a link to static pages, then you need to make those pages dynamic and turn on URL rewriting in your dynamic code. Also, note that automatic rewriting is not a good idea in general. How does tomcat know which URLs to rewrite, and which ones not to? For instance, if your static pages refer to http://www.slashdot.org you probably don't want any rewrite to occur there. You may need to look at using an invisible (or very small) frame to enclose the static page requests inside of a small JSP/servlet to maintain your state. While I haven't thought it through completely, you may be able to use some tricky URL magic (like mod_rewrite I thnk on apache) to make your static links autmagically come through your JSP wrapper, which maintains the app state. WOuld probably be easier if all your static pages use relative links.

Well,
for the first one, they don't have a session yet - so the JavaScript just needs

This approach sounds promising, with much less of a

The way the site works right now, any page that leaves the
site is brought up in a separate window anyway.
So by the same token we could have any url that needs

This project has many restrictions: No
cookies, No frames, Applets
only when explicitly authorized.
All which ultimately hurt performance. One question I
have is if every single page in the entire site is

to integrate with Apache? My understanding is that Apache would only serve the static pages requested directly. Is
that correct?

RE: Using Jasper for template processing?
Remember, Servlets are not necessarily HTTP beasts. The servlet spec (from
my perusal) specifically leaves open what kind of environment the servlet
will live in. This is why there are specific HTTP extentions of the base
servlet classes. Now, that being said, I don't know of any other way to use
the servlets except in a web environment. But, being able to do what JG

Subject: Using Jasper for template processing?
Hello Tomcat developers and advanced users!
I have following question:
I would like to use Jasper engine for template processing. I use
Tomcat with JSPs and its good, but I would like to alter Jasper usage
this way:
An JSP page is compiled into a Java source where the user's JSP
page extends the class HttpJspBase and overrides several methods
notably _jspService().
I want to use Jasper for more generic task. Template processing
independent on Servlets and HTTP. Imagine following interface:
public interface Template {
void renderTemplate(Writer out) throws java.io.IOException;
}
I want to alter Jasper to process files with JSP-like syntax (of
course with other intrinsic variables accessible inside the
renderTemplate() method) and generate Java source code implementing
the Template interface and than compile the source code using Java
compiler into executable classes. Then load and run generated classes
as they have been written manually.
So I ask:
1) is is possible or is Jasper tightly coupled with HTTP and Servlet
API?
2) if it is possible, how to do that? (which classes can be re-used,
which interfaces and classes have to be re-implemented
3) how much time it can take (1 day, 3 days, a week, two weeks, ...)
Thanks for any comments and suggestions.
