Re: Multi-part response
If the browser supports it you would send the whole page in one multipart response a bit like a mail message. Here's one way to do it: So, you'd have to buffer the response. Then create a javax.mail.internet.MimeMultipart and add BodyParts (javax.mail.internet.MimeBodyPart) for the html and each of the images. For each image link in the html you'll have to change it for the Content-Id of the corresponding image MimeBodyPart. For example (IIRC): For an image blah.gif with a Content-Id of piccy1 replace the contents of the src attribute of the image tag in the html with cid:piccy1 http://www.ietf.org/rfc/rfc2111.txt javax.mail.Multipart has a handy writeTo(...) method so you can splurge the entire thing down the response outputstream.

You don't need a WAP gateway.

Sure. All the big boys sell gateways. The Nokia gateway seems to be used (or at least was) a fair bit within the operators themselves. Here's a Nokia SDK which may be of use: http://www.forum.nokia.com/main/0,,034-741,00.html The major OSS gateway is kannel (http://www.kannel.org/) The last time I looked there weren't any mature OSS gateways written in java.

Re: advice on auto logout servlet
I did an AJAX version of this a couple of months ago.

Re: JDBC/MySQL user login goes stale
Also be aware that autoReconnect=true only works (according to the mysql docs) for Connections with autocommit set to true. If you are using a connection pool make sure it checks the validity of Connections every so often. This is configurable for DBCP: http://jakarta.apache.org/commons/dbcp/configuration.html If you aren't using a pool then implement some sort of heart beat code as the previous poster suggested. HTH, Jon Lists wrote: This is an interesting problem. But first try setting autoReconnect=true in your connections string. If you continue to experience a timeout.. Check the logs, and see what specifically is happening. You may be experiencing an exhaustion of connections not being released properly. If it is a true timeout and autoReconnect does not solve it... try writing a heart beat (1/hour) to test if this keeps it up and running. Be cognizant of connections NOT being returned back to the pool by a proper close. Which does not mean that you're not closing correctly from your code, you maybe experiencing a close issue with JDBC. So, the version of JDBC is certainly another item to check. :-) Hope that helps! jes On Nov 29, 2005, at 2:21, David W.

Re: Extending webappclassloader
Our custom loader sits in a jar in $CATALINA_HOME/server/lib Our classloader uses different parent classloaders depending on which version of TC is running. In 4.1 we just use the parent classloader as supplied in the constructor. In 5.0.x we use the classloader of WebAppClassLoader as the parent. It's a while since the code was written but I seem to recall the creating parent is the bootstrap classloader which knows nothing of the server classloader, and hence can't find the servlet api classes. We haven't tried it in 5.5.x yet. HTH, Jon Niels Soeffers wrote: Hello, I have a problem extending the webappclassLoader. In the company I work for, we are using eclipse as our IDE.

Re: problem calling request.getParameter(myparameter) in jsp
Your underlying problem is the exclamation mark at the start of your
scriptlet. This makes the jsp ompiler put free standing code into the
init method or creates methods on the servlet that you can call within
your jsp. Without the exclamation mark the compiler inlines the
scriptlet into the _jspService() method, which is the behaviour you require.
So, you should have:
% String query = request.getParameter(display) ; %
instead of
%! String query = request.getParameter(display) ; %

Re: How to configure my Realm class from context.xml?
Your Realm implementation needs to sit in the server classloader as the Realm interface is only defined there (in catalina.jar).

Re: How to reduce bandwidth (meaning message size) with Axis
Compression works very well. I added a homegrown GZip filter to the AXIS urls and also saw approx 10x compression. There are also a number of similar OSS Filters out there. There were .NET clients accessing the web-services and they needed a tweak to handle the compression: http://www.dotnetjunkies.com/Tutorial/90D3B3E0-6544-4594-B3BA-E41D8F381324.dcik The original messages could be of the order of 3MB and the client's network pipe wasn't so big: GZip was a saviour :) Jon David Rees wrote: On 3/15/06, David Kerber [EMAIL PROTECTED] wrote: Are there any adjustments I can do to my Axis settings to reduce the bandwidth usage on my SOAP requests? XML compresses very well, typically I have seen compression ratios over 10x! The key is to get your clients and servers configured to handle content compression. If you have Tomcat behind Apache, use mod_deflate. If Tomcat is running standalone, have a look at the default server.xml to turn it on. Finally, you have to pray that your clients have content compression support! The net result has been a huge bandwidth win in my experience, that when serving your typical html content. -Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Tomcat Valve, how to Create Pattern
I may be wrong but I think there are only two predefined names: common
and combined. For all others you set the pattern attribute to the
required number and ordering of pattern elements as defined in the docs.
From the docs:
The shorthand pattern name common (which is also the default)
corresponds to %h %l %u %t %r %s %b
So, for example, if all you wanted was the url, the time it took to
serve and the user agent you would set the pattern to:
%U %D %{User-Agent}i
The latter pattern element I got from the javadoc:
http://tomcat.apache.org/tomcat-5.5-doc/catalina/docs/api/index.html

So where can I define a pattern for my needs, give it a name, then use

Does anyone have an example of that?

Re: InputBuffer and Posting Data
After re-reading the original description you should probably be aware of this portion of the javadocs for request.getParameter: quote If the parameter data was sent in the request body, such as occurs with an HTTP POST request, then reading the body directly via getInputStream() or getReader() can interfere with the execution of this method. /quote The reverse is probably true, too. The getParameter call probably affects the reading of body data for POSTs. Are the parameters you need in the query string? If so you may need to parse that yourself instead. The above may not be the problem. But...

You cannot do a top-level build unless you move the contents of /jasper/jasper2 up into just /jasper. Sorry. My bad. In removing the unnecessary jasper2 directory, I missed the src part of build process. The directory move is the only difference.

Re: web.xml error page redirect, Java EE 5
Have you tried the request attributes specified in section SRV.9.9 Error Handling of the servlet spec? Specifically, the request attribute named javax.servlet.error.request_uri. HTH, Jon Tomas Pop wrote: Hello, I have a problem with change of the method HttpServletRequest.getRequestURL() in Java EE 5. I have this situation: URL matches http://server/app/page-key-word-string These URLs generates 404 Tomcat error page, which redirects (according to web.xml settings) to redirectServlet, where I get the client URL by calling request.getRequestURL() and then I parse the page-key-word-string and select the matching page from DB. This worked fine in Java EE 1.4 but in Java EE 5 the getRequestURL() method returns the path to redirectServlet instead of the client URL. Please, where can I get the path specified by the client after Tomcat 404 error page redirection? Or is there other way to implement these functionality?

Re: tomcat pauses then crashes after a period of time
Another thing to note is that mysql automatically closes idle
connections after 8hrs (by default).
You can configure DBCP to test on borrow or to periodically squirt some
sql down idle connections.

Chris,
Thanks very much for the suggestion.
I'm not using connection pooling at this stage. I have deployed my web
service scoped as an Application. It only uses one connection, and the
classes maintain some medium sized data structures which I do not want to
have to re-create each time the service is consumed. I'll investigate the
pooling, as an auto-reconnect feature will be necessary in some form or
another, and if DBCP can do it then that would be great, even if I maintain
only one connection I guess...

Heh, well /there's/ yer problem.
Firewalls are known for terminating idle TCP/IP connections after a
certain period of time, which is unfortunate, as many deployments put
the database behind the firewall and the app servers out front.
Are you using any kind of database connection pooling? If so, perhaps
there is an auto-reconnect feature available for that component. For
instance, Jakarta Commons DBCP includes such a feature. Once you are
using DBCP, your code doesn't have to know how to handle unexpected
disconnects like that, since the connection pool handles the automatic
reconnection for you.
Hope that helps,

Re: one filter for all webapps?

Re: many No Referrers in logs
Additionally, many client-side Security/Anti-Virus software packages automatically remove the referer header from requests. Markus Schönhaber wrote: Robert Kudyba wrote: We have our server.xml file set w/ the following entry: Valve className=org.apache.catalina.valves.AccessLogValve directory=../logs prefix=ws_access_log. suffix=.txt pattern=combined However, there are still many log entries showing no referrers. Some are from user spiders such as the following: [...] So should we assume that if there is no referrer logged than the user was just using links within the site? No. IMO you should first of all assume that no-one guarantees that a client is sending any referrer headers at all. Most modern browsers will do so but it is more or less easy to change their configure to not send them. And moreover, it is very easy to use a proxy the removes referrer headers from all requests - idependent of the client used or it's configuration. Because of this you can't draw any safe and definite conclusion from the absence of referrers. That said, David's answer stands: in propably most cases, no referrer means the request was made from a bookmark or by typing the URL into the address bar and not by clicking on a link on some page (which then would be the referring page). Wether or not the referring page was within the site is of no relevance.

Re: MyPrincipal cannot be resolved to a type
Fair enough. We also extend RealmBase and just override hasRole(Principal principal, String role), which is the only place GenericPrincipal is referenced in RealmBase. We use our own storage mechanism for Roles. http://svn.apache.org/repos/asf/tomcat/container/tc5.5.x/catalina/src/share/org/apache/catalina/realm/RealmBase.java As to moving server/lib/* to common/lib/*.

Re: problem with doPost method - executed twice
You need to look at your access logs. You'll probably see two requests.
Your form submit button calls javascript which also calls form.submit().
I think, if you don't return false from the javascript you will get two
form submissions. Try removing the form.submit() from the javascript.

Re: Getting the date/time from the client
The HTTP spec (rfc2616) says clients should only send the Date header
with http messages with body content (POST, PUT) and even then it's
optional.
Try adding a date string as a parameter on your GET request which your
servlet can then parse from request.getParameter(...).
One way to do this would be to change your link to a form with a hidden
input field for your date value. Add an onclick/onsubmit javascript
handler to your form button which sets the value of the hidden field to
the current date in a format that your servlet will understand.
for example:
function setDate(form) {
form.dateField.value = new Date().toString();
}
Example assumes a hidden form input field with name dateField.

Re: Tomcat Memory Status?
Hi OP, They probably mean what they say ;) See the jdk javadocs for the System/Runtime classes. The Free Memory stat often causes confusion initially. It's the free memory in the block of RAM currently assigned to the JVM. So, it looks like at startup Tomcat is assigned 8Mb under your JVM on Win95. The max the JVM is set to use is 64Mb, meaning you really had ~58Mb free at the time of the snapshot. How much physical memory do you have in the box? You can tweak the maximum available memory using JAVA_OPTS http://tomcat.apache.org/faq/memory.html#adjust HTH, Jon Propes, Barry L wrote: MB Not GB? How are you even running Win 95 with 63.56MB?

Re: Missing Request Parameters
Rache, Tools like ieHTTPHeaders and LiveHTTPHeaders will also help you determine what the browser actually sends to the server, including any redirects caused by 302 response codes. HTH, Jon Rache, But this usually occur after redirects. This is what I was going to ask about: if you fail to put all the important parameters into the redirect, then you will lose them. For example, if you have a form handler that accepts 5 request parameters, you cannot simply say: response.sendRedirect(/foo/bar/baz); and expect those request parameters to be included for you. You must do this: response.sendRedirect(/foo/bar/baz?a=bc=de=g[etc]); getRequestDispatcher(url).forward(req, resp); Forwards should retain the request parameters. I've read something with 302 codes/redirects having to cause lost parameter/session info. This is not an HTTP problem; 302 codes can include complete URLs, including request parameters and even cookies (since they are just stored in the HTTP headers). Check your code very carefully to see where the parameters disappear, and I think you'll find that you are not building your URLs for redirection properly. -chris - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Missing Request Parameters
Erm. ok. Where does the redirectURL variable come from? Unless it has
parameters encoded into it that will be your problem.
Also, be a bit wary in using the RequestDumperValve with non-ascii
charset data as it can corrupt some parameters:
http://marc.theaimsgroup.com/?l=tomcat-userm=112530311007782w=2
The above (and other similar threads on this list) is why I tend to use
the browser plug-ins first.

-Jon, we have enabled the RequestDumperValve in the tomcat server.xml to
enable request logging. That way, we are able to monitor the requests coming
in. The logs helped us to see that no parameters where set in the request.
This application is connected to IIS thru the AJP connectors. Aside from the
parameter-setting code which I need to check, could this connection also
cause request parameters to be dropped? I have quite a bit of a problem
checking the urls with parameters set since this happens in production and
happens on and off. I can't even see the page source to check on the url set
since the pages aren't cached. Any tips on these?
I'm really grateful for all your inputs!

Re: HTTP 408 Login timeout
If you have a custom error page set up you can trap the 408 response code and redirect to an appropriate resource. Works for me :) Alternatively, you can set up a meta refresh on your login page so you never get the 408. Of course, because the refresh has to go to some protected page and not back to the login page you lose the exact protected resource that the user originally requested. But hey, they couldn't have wanted it that badly if the session timed out while waiting to login ;) HTH, Jon C S wrote: I'm dealing with a problem where if a user hits a secured page and is forwarded to a login page (using Form Auth).

Re: After stopping tomcat, the tomcat process still appears to be running
You've also got other candidates such as database connections, JMS connections etc which could spawn threads (For example, for keep-alive functionality). The easiest thing to do is a thread dump (send the process a SIGQUIT signal) after stopping tomcat to see which thread(s) are keeping the JVM up. Once identified you need to fix your code. HTH, Jon Tomas Hulek wrote: At JVM shutdown, the JVM is terminated only if all remaining running threads are daemon threads. Therefore, if the application starts own threads, it is necessary to ensure that 1) either all these threads are destroyed before JVM shutdown by calling the stop() method for each of the threads, 2) or make them daemon threads by calling setDaemon() right after thread creation.

Re: login page behavior and the 2.4 specification
Quick and dirty solution is to have your login page make a meta refresh every, say, ten minutes pointing to the index page of your protected content. This simple approach works for us. We also catch unexpected errors coming back from the login form submission and re-present the login page. As you say it's not ideal and better to avoid as many instances as possible. HTH, Jon Michael Swierczek wrote: I'm receiving a 408 error, and I do understand why. I just can't figure out an end-user friendly way to avoid it. The application runs on Tomcat 5.0.28 with form-based authentication. It is accessed by some end users from regular PCs, but most connect from kiosk web browsers. When someone initially connects, a new session is generated, they see the login page, they enter their credentials, and login is fine. Then they log out, and the login page sits with no activity for hours, days, or weeks. The next user comes along, enters their credentials, and submits. The request reaches the server with an expired session id and a 408 error is generated. I've read parts of the 2.4 servlet specification, and I realize this is the expected behavior. But obviously this isn't what we want, it is annoying to end users (even if I hide the 408 error and transparently redirect back to the login page). I've never used Ajax, but I imagine it would be possible to transparently retrieve a new session ID from the server as soon as the user starts to type a username or password. Assuming I can do that, it would solve the problem - but I am almost positive other solutions to this existed before the advent of Ajax. I would really appreciate any help, or suggestions as to where to search for more information.

The request reaches the server with an expired session id and a 408 error is generated. I've read parts of the 2.4 servlet specification, and I realize this is the expected behavior. But obviously this isn't what we want, it is annoying to end users (even if I hide the 408 error and transparently redirect back to the login page). I've never used Ajax, but I imagine it would be possible to transparently retrieve a new session ID from the server as soon as the user starts to type a username or password. Assuming I can do that, it would solve the problem - but I am almost positive other solutions to this existed before the advent of Ajax. I would really appreciate any help, or suggestions as to where to search for more information.

Re: a discrepancy in webapp behavior in two environments
Mark, Take a look at the LiveHttpHeaders plug-in for Firefox. It may help you debug this on the client side. Temporarily enabling the RequestDumperValve on the server side will enable you to see if cookies are reaching the server. HTH, Jon Aronszajn, Mark wrote: Thanks for the information.

If you're not appending jsessionid ro the URL, you must be using cookies to allow the server to identify the client. Some smart (?) firewalls (or proxy servers) can be configured to drop cookies.

Re: Listener vs. load-on-startup
The order of events is:
Startup:
All listeners get called.
All filters, load-on-startup servlets get inited.
Shutdown:
All filters, servlets get destroyed.
All listeners get called.
So, it is possible for the combination of load-on-startup init +
contextDestroyed to do the same job as just using one
ServletContextListener. But why do it? IMO load-on-startup was a hack in
the early spec versions so that application data could be set up.
ServletContextListener was added as the way forward ;)

Jon

Hi all,I have some problem with Listener and load-on-startup,I serch on
google and I find this article below,it do a lot good to me, but I still want
to ask , using the init() of a servlet and the contextDestroyed() of a
listener are equal to Iusing the contexInitialized() and the
contextDestroyed() of a
listener?

Subject: API 2.3: Listener vs. load-on-startup
I have a few classes that need to be loaded by Tomcat before it starts
to serve any requests. One of these opens a database pool, another
opens a logger, etc. The traditional way to do this is with
load-on-startup like this:
servlet
servlet-namestartlogging/servlet-name
servlet-classstartlogging/servlet-class
load-on-startup1/load-on-startup
/servlet
which calls the init() method of the class.
However, I need to have an object installed into the ServletContext
object before any requests can be serviced. The init() method of a
servlet seems to have no access to the ServletContext object (is this
correct?).
You have access to the servlet context via the getServletContext() method
of the servlet -- it is pre-initialized to work for you. However, using a
listener is the better way to do this in a Servlet 2.3 environment.
Because of this, I am thinking of using the new listener
declaration to achieve this same goal. I can declare a listener like
this:
listener
listener-classdostartupstuff/listener-class
/listener
and then in the dostartupstuff class, I declare a method:
public void contexInitialized(ServletContextEvent e) { ... }
which will be called as soon as the context is created.
Is this the right way to do this?
Yes. That is exactly what context listeners are designed to do.
Why is it better than a servlet init() method? Because the container
gives you *no* guarantee that it will keep a servlet loaded for the
lifetime of the application (although many of them do), so if you clean up
your resources in the destroy() method -- such as closing database
connections -- this might happen to you at a bad time. The
contextDestroyed() method of your listener will not get called until the
application is really being shut down.
And is there a way I can control
the order in which listeners are called?
At startup time, listeners are called in the order they are defined in the
deployment descriptor -- at shutdown time, they are called in reverse
order. For more info, see the 2.3 spec:

Re: hi,problem when shutdown tomcat!
Chuck answered a similar query recently: http://marc.info/?l=tomcat-userm=118113828210257w=2 Your servlets are serving long-running requests (or are in infinite loops, dead-locked etc) when you are trying to shutdown tomcat. The first thing I'd do in this situation is SIGQUIT tomcat to get a stackdump of the running threads. With that you can usually determine the changes you need to do to your servlets, if required. If the stackdump isn't a help I'd attach a profiler to see where your servlets are spending the time. I like the one bundled with netbeans. I'm sure others on the list have their own favourites.
