Re: Migration 4.1.27 to 4.1.30 - Servlet-Configuration won't work

Every other request goes to the app-servlet. In 4.1.30 every request goes to the app-servlet. Even http://xxx/login and http://xxx/appmanager. Is this a typo or not? * You have /lappmanager URL pattern (see first l letter), but request for http://xxx/appmanager;. * Second, you have /login/ URL pattern (see suffix slash), but request for http://xxx/login;. So none of your mappings triggered, what leads to default app-server invocation. And also the method request.getPathInfo() return null. I don't know why. As of request.getPathInfo() method, please read J2EE's specs, it says: cut Returns: a String, decoded by the web container, specifying extra path information that comes after the servlet path but before the query string in the request URL; or null if the URL does not have any extra path information /cut So for example you'd have request URL like http://servername/webapp/mappedname/and/this/fake/path;, getPathInfo() would return /and/this/fake/path, I guess.

I don't understand how to determine whether the new session is truly new, or if it's a new session because a previous session timed out. Could I use a filter and check the incoming session ID and if the session ID isn't in the list of session IDs that the server knows about, assume that it's an expired session? Yes, this may be the right solution. Store a hash in a singleton class and fill it with session ids that has expired (add a new hash pair in every invocation of sessionDestroyed()). And at every request check that: 0) HttpSession.isNew()==true . 1) HttpServletRequest.getCookies() array contains an entry that matches one of your hash pairs. That way you may determine if that session is truly new or an expired one. It's just a guess. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Subject: SESSION VARIABLE BECOMES NULL AFTER SOME REFRESH
Hi,
I have a jsp page which is refreshed atuomatically every 10 seconds.I
get and put values in the session by using the implicit session variable
. Everything works fine for say 2-3 mins after that the session becomes
null and throws a null pointer exception.
IN the try block I even have a code as
try {
if (session == null || session.isNew()) {
//do something
} else {
//do otherwise
}
}catch(Exception e )
{ //print stack trace and value of session }
I get a null pointer exception and session is preinted as null but even
the if block is noit executed . I printed the value of
request.getSession(false);.This gives me session object ,where as the
implicit session does not have this after many refresh interval . During
the first few refresh both have the same value.
May be some logic deep in your code invalidates session somehow? You
can set up RequestDumperFilter to look at HTTP headers you (your
browser) send and what is received. I don't know if that filter
available in Tomcat 3.2, 'cause I use it since 4.1 time, but you can
grab it from recent Tomcat distribution. Or you can use
javax.servlet.http.HttpSessionListener to be notified when a session is
about to be invalidated or timed out.
Also note that this runs fine in Windows ,I get this problem only in
UNIX . I use tomcat 3.2 in unix and view using IE in windows

Hi there.

There is a problem when i try to get or to insert Hebrew characters.
i get in DB , for both if i write yair in the url in Hebrew , or i
write yair in %E9%E9%E9%F8 which is the decimal representation
For example , if i insert a string in Hebrew , it looks like this ? (
in SQL +)
this is how i get the requests from the url
Enumeration paramEnum = request.getParameterNames(); // get request
parameters from the url , in param/value pairs
String myParam = (String) paramEnum.nextElement(); //get parameter

String myStatment = insert into mytable values('19', '+myValue+') insert

Re: Servlet on Tomcat + Oracle +ISU 8859-8 (Hebrew CharSet) - encodin g problem
This is my problem also, and sadly it's so since long time I use Tomcat.
I've attach a simple little test case .war file to reproduce the
problem. There are four HTML forms there, two of them submits to JSP
page (GET and POST methods), others go to servlet (same methods).
On top of it is a select field allowing to define an encoding for
future submits. It acts as following: after choosing it and submitting
that select the JSP page is reloaded with that encoding, setting its
response.setContentType() and setting session attribute named
tHAVW07QUf (for uniqueness, see below). Now, one can submit any form
presented below.
I've deployed a filter.SetCharacterEncodingFilter (taken from
standard Tomcat distribution), with one modification: during every
request it reads session attribute tHAVW07QUf and sets requests'
encoding accordingly. If that attribute is absent, it reads its init
parameter given in web.xml as usually. So, instead of hard-coding
character incoding in web.xml, I can set it online. According to
filters.RequestDumperFilter (also Tomcat's standard filter) it works.
So, let's see what we have here. The result on my machine is that
any GET methods produces broken output of the parameter passed as
URL-encoded %XX%XX%XX string, actual encoding of which is set by select
box on the first page. Any combinations of encoding, submit methods and
target actions (JSP or Servlet) give me broken output, except two of
them -- utf-8 POST to JSP and utf-8 POST to Servlet.
I looked at Tomcat's some source files, namely
org.apache.catalina.util.RequestUtil.URLDecode(byte[], String) and
org.apache.catalina.util.RequestUtil.parseParameters(java.util.Map,
byte[], String), and see how url-encoded request parameters are parsed,
but I don't know if it's the right place to see.
Ah, and one note. I tried to run Tomcat with
-Dfile.encoding=koi8-r option to set default byte[]-String conversion
mapping to koi8-r (for example), and even this does not help me much,
though it sets the new default.
This behaviour was there on 4.x and 5.x versions, seems like nothing
is changing.
I don't state that I've done all tests correctly, so in any error
please fix my mind. The only question is: how one can universally and
correctly handle non-ASCII request parameters and get rightly decoded
output?

Thanks Veniamin Fichin,
Can you copy paste your code that solves the problem?
The output encoding of view.jsp page was hard-coded utf-8 value. I
changed it to be more flexible by lookling into session attribute which
was set previously. Code snipped follows.
--- view.jsp: ---
%
String encoding=(String)session.getAttribute(tHAVW07QUf);
if (session!=null) {
response.setContentType(text/html; charset=+encoding);
}
%
%@ page pageEncoding=utf-8 info=Test: localized parameters%
!-- ... JSP body ... --

Session attribute setting you can see in source code. But bear in
mind that this fix works with POST method only (at least for me).

And I see that tomcat docs is wrong in DataSourceRealm description,
because attribute list there is not reflect real things in code.

DataSourceRealm does not exists?
Hi list! I've faces the strange problem that I don't understand. I need to configure some authentication at some part of our site, so I chose FORM based authentication through DataSourceRealm described in Realm Configuration HOW-TO. First, I've mentioned that explanation about DataSourceRealm and attribute list are strangely similar to JDBCRealm one (is it just a copypaste?) -- that is, in some places there is JDBCRealm where DataSourceRealm should be. Second, attribute list for DSR has no differences with JDBCR -- how should I declare jndi name for a data source? But it the Example subsection below there is dataSourceName attribute, and className is org.apache.catalina.realm.DataSourceRealm instead of org.apache.catalina.realm.JDBCRealm listed in attrubute list above. Is it documentation error or not? Third, and most strangest, is that there is _no_ org.apache.catalina.realm.DataSourceRealm class in my Tomcat distribution! I looked in $TOMCAT_HOME/server/catalina.jar and didn't find this class. My Tomcat is 4.1.16, OS is Win2k. I've searched marc.theaimsgroup.com and Google, and didn't find any message related to my question. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Sorry for the stupid post, found my fault... DataSourceRealm is in 4.1.18, shame on me... I have another question now. Servlet 2.3 spec, subsection J2EE12.5.3.1 Login Form Notes, says that for FORM based authentication action form attribute should always be j_security_check. I think I set constraints right, because I see login page when I request any page in closed area. But after submitting the form my URL becomes /context/j_security_check, and nothing happens.

Thank you for every answer! Sounds like you should *really* be using something other than HTTP for this kind of thing, since there is no such thing as a real server push. You might investigate using some sort of IRC environment, or packages like Jabber http://www.jabber.org. Yes. I only thought that I can thread my servlet so each new client and serve them separately. It's possible to simulate server-push using web browsers that periodically poll for new information, but the approach doesn't scale very well -- most of the time your server will get hammered by requests that don't end up changing anything, and you can't get information out any faster than the polling interval of your clients. It would be too simple, and it's unacceptable. So, you think it's not possible to do such a thing using Tomcat as an servlet container? No matter what underlying technology you end up with, I'd suggest doing some research on how multiple threads work in Java.

Re: multiple servlet instances?
Craig R. McClanahan wrote: May be my question is not too close to this topic, but it may be related. It is below... I was reading in a book today that JSP implementations are still permitted to create multiple instances of the ... servlet in order to provide improved performance. Does Tomcat/Jasper do this? Might there be multiple instances of a servlet (JSP-generated or otherwise) in my JVM? You might want to be cautious believing anything that book says about any topic, unless it correctly explains what is really going on. What book said this? For anything from Servlet 2.2 on (that's quite a long while back), it is not legal for the container to create more than one instance of a particular servlet definition *unless* that servlet implements the SingleThreadModel interface (or the JSP page has the isThreadSafe=false attribute on its % page % directive). The other thing to note is that doing this would not improve performance -- at best, it will have zero impact, but it's actually pretty likely to be negative (because the container is going to have to manage the multiple instances, because the maximum number of simultaneous requests to that servlet is now limited to the pool size you've configured, and because they take up more memory space). The only reason that SingleThreadModel exists is to allow you to create a servlet or JSP page that stores per-request state information in instance variables of the underlying class. This is not a good programming practice -- you should instead use local variables only, so that a single instance of your servlet or JSP page can handle any number of simultaneous requests.
