Problem Parsing Request Parameters
Certain users of my website are having issues with respect to submitting a form on a page. Not all users are experiencing this problem, and I've yet to replicate it myself so it makes the situation even more complex. I have an icking suspicion that its related to the user's browser, but I've tested on the same browser version/subversion without a glitch. Here's the scenario: 1) User goes to page. 2) User fills out form. 3) User clicks submit. 4) JSP page then performs sanity checks against submitted data. In the event of a failure on the sanity checks, page is redirected back to previous page. Simple enough. Well, users are filling out the form and clicking submit with valid infromation, yet when I parse the parameters out of the request, I'm finding none of the form values from the previous page. I then decided to investigate further and log out all request information in the event that these sanity checks fail. The following is what I logged out: - Attributes: javax.servlet.request.cipher_suite = [SSL_RSA_WITH_RC4_128_MD5] javax.servlet.request.key_size = [128] javax.servlet.request.ssl_session = [433162398579970fee9289baa9ac832b8558dcc409382f62cb67a3499b80] Parameters: Cookies: JSESSIONID = [FCB31837FFBD2C0D9F986C42B698BADE] contact_value = [ABC] duplicate_type = [None] duplicate_time = [] mortgage = [] lender_id_label = [] title_alternative = [] can_place_orders = [Y] flood_default = [126] can_cancel_lol = [N] contact_label = [] lender_id_value = [ABC] census = [] loan_no_label = [] delivery_method = [Online] apprasail = [] delivery_address = [] title = [] Headers: accept = [image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-excel, application/msword, application/vnd.ms-powerpoint, application/x-shockwave-flash, */*] referer = [https://WEBSITE_URL/CreateOrder.jsp?applicant2HomePhone=streetName=Ma in+Stapplicant2WorkPhone=applicantOtherPhone=ownerEstimate=applicant 2WorkPhone2=revisionOf=applicantWorkPhoneExtension=unitType=preFixDi r=Eapplicant2OtherPhoneAreaCode=applicantOtherPhone2=applicantMname=L skipstep=nonezip4=applicant2HomePhoneAreaCode=applicant2OtherPhone= applicantLname=DoestreetNum=applicantHomePhoneAreaCode=zip=40845pass code=HomeorderHeaderGeneralNotes=applicantHomePhone2=propertyLoanNumb er=productTitle=applicantFname=Johnapplicant2WorkPhoneExtension=appl icant2WorkPhoneAreaCode=applicant2Mname=JunitNumber=applicantWorkPhon eAreaCode=postFixDir=productAppraisal=propertyParcelNumber=applicant WorkPhone2=applicantOtherPhoneAreaCode=city=HulenapplicantHomePhone= applicantWorkPhone=applicant2Lname=Janeapplicant2OtherPhone2=applican t2HomePhone2=streetType=state=KYcontactId=10productMortgagePrep=pro ductFlood=Yesapplicant2Fname=Doe] accept-language = [en-us] content-type = [application/x-www-form-urlencoded] accept-encoding = [gzip, deflate] user-agent = [Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)] host = [WEBSITE_DOMAIN] connection = [Keep-Alive] cache-control = [no-cache] cookie = [JSESSIONID=FCB31837FFBD2C0D9F986C42B698BADE; contact_value=ABC; duplicate_type=None; duplicate_time=; mortgage=; lender_id_label=; title_alternative=; can_place_orders=Y; flood_default=126; can_cancel_lol=N; contact_label=; lender_id_value=ABC; census=; can_view_insurance_tracking=N; loan_no_label=; delivery_method=Online; apprasail=; delivery_address=; title=] content-length = [0] - There are many interesting things about this request.

Configuring Tomcat to delay accepting of connections until apps are ready/loaded
I'm running into a particular problem running web services off of tomcat in our production environment. It seems that our client is requesting services from us at the exact time that Tomcat is being rejacked. Tomcat seems to be accepting the connection quickly, but doesn't respond to it for another 25 seconds or so. Are my observations correct? Does Tomcat open its sockets before it can physically handle the request? If so, is there some way to configure tomcat to open the sockets just prior to having all web applications loaded? I'm working on a 15 second processing time window, and if Tomcat accepts the request and waits 25 seconds before passing it along to my code to process it, then I've already burnt my 15 seconds. Any help would be appreciated. Here is my current environment: - Tomcat: 4.1.30 - JDK: 1.4.2_06 ___ Jeremy Nix Senior Application Developer Southwest Financial Services, LTD.

Tomcat 5 and returning PDF in response outputstream
Has anyone else had trouble rendering PDF's (in Internet Explorer) when sending the pdf directly into the response outputstream and rendering in Internet Explorer? I realize there are a lot of factors at work here, but I find that my configuration works fine when I switch to Tomcat 4.1.30. I'm setting the content type and content length on the response. The code I use is below: pdf = generatePDF(); response.resetBuffer(); response.setHeader(Cache-Control, max-age=30); response.setHeader(Content-Disposition, inline; filename=generated.pdf; size= + pdf.getBytes().length); response.setContentType(application/pdf); response.setContentLength(pdf.getBytes().length); response.getOutputStream().write(pdf.getBytes()); response.flushBuffer(); If I access my url with Netscape, the pdf displays correctly. If I save it out to the filesystem (on server side), pdf displays correctly. It's just something with the configuration of Tomcat 5 and Internet Explorer that is not working correctly. The same code posted above works for both Netscape and IE when run under Tomcat 4.1.30. Has anyone had similar problems? _ Jeremy Nix Senior Application Developer Southwest Financial Services, LTD.

Session Replication w/o Multicast
Is there currently a way of replicating session information across multiple tomcat nodes without multicasting? If not, has any extended the Tomcat API to support this? The reason I ask is because we are using a hardware load balancer, and it does not support multi-casting. One thought is that we could upgrade our hardware to a load balancer that supports this (not sure one even exists), but I'm sure that there are other means of performing replication besides multicasting. Using a database as the session persistence layer is one thought. Direct tomcat node to tomcat node in memory session replication is another thought. Just thought I'd see what ideas/solutions are out there. _ Jeremy Nix Senior Application Developer Southwest Financial Services, LTD. (513) 621-6699 x1158 www.sfsltd.com

I've misphrased. What documentation I've come across indicates that Apache (or IIS) is necessary to configure tomcat as a cluster. It very well may be possible, which is why I'm asking the list.

Need example configuration for Apache/Tomcat/JK2 and multiple virtual hosts
I have a need to have Apache and Tomcat both handle requests for multiple IPs (hosts). I've initially set up a httpd.conf that defines 2 virtual hosts A and B. Both use JSPs/Servlets, so they both have references to JK2. I've kept the JK2 configuration simple and used localhost:8009 for both hosts. On the tomcat side, I have 1 engine with 2 separate hosts listening on their respective IP's. I've defined 3 connectors all running on the default address (localhost): NON-SSL, SSL and AJP/JK2. I also have this same configuration on 2 separate boxes and they are both being load-balanced through a local-redirector. This configuration seems to work as expected when I reference the defaultHost in tomcat (virtual host A), but when I reference a page hosted by virtual host B, I seem get unexpected errors (sometimes recursive in nature). So, has anybody experienced this? Does anybody have a sample configuration (load balancing with multiple virtual hosts) that I can mimic? _ Jeremy Nix Southwest Financial Services, LTD.

Its easier to do on tomcatB since you can use a Valve or servlet filter and stay out of the business logic.

RE: How do i handle session-timeout in an acceptable manner?
The problem with your solution is, that the application does not know
where to continue after the login page. This will result in an error.
If you want your login page to redirect you back to the page that the
user timed out on, then why don't you just add a hint to the login url
so that after the user has logged in, then your application will know
where to redirect them.
I have implemented this workaround:
protected void doGet(
HttpServletRequest httpServletRequest,
HttpServletResponse httpServletResponse)
throws ServletException, IOException {
String reqURI = httpServletRequest.getRequestURI();
if ((reqURI.indexOf(/actions/) != -1)) {
// Calling of 'actions' via get is not allowed
String referer = httpServletRequest.getHeader(referer);
if ((referer != null)
(referer.endsWith(/loginpage.jsp))) {
// if this happens, we probably had a Time-Out
RequestDispatcher dispatcher =
getServletContext().getRequestDispatcher(/timeout_info.jsp);
dispatcher.forward(httpServletRequest,
httpServletResponse);
} else {
throw new ServletException(Action forbidden.);
}
} else {
// Call shared, standard request processing code.
processRequest(httpServletRequest, httpServletResponse);
}
}
What it does: if there is a get call to an URL that should be
called as
post, and the referer is the login page, then forward the request to
some kind of informational message.
Of course there can't be any guarantee this works with coming
versions
of Tomcat. So i would like to have an general solution.

Subject: How do i handle session-timeout in an acceptable manner?
I have a built a web application on Tomcat 4.1.18. The
application is
running with a HTTPS connection. session-timeout is configured and
works
so far. But i am absolutely not satisfied with what happens when a
timeout occurs. The web application is configured for form based
authentication. When the connection has timed out, the user is
presented the login page when he does his next action. And,
all data
saved with the session are lost. Fine - i could live with that.
But what happens in a real case:
- The user waits too long - timeout.
- The user pushes an INPUT type=submit and creates a POST
operation.
- Tomcat redirects to the login page.
- The user logs in.
- Tomcat redirects to the original aim of the post
operation, but he
does it as a GET operation. Alternative 1:
- My application does not allow get operations at this place ==
Application Error.
Alternative 2:
- The application allows the vulnerable get operation, but
the button
that was pushed is not passed anymore == Application Error.
Now what can i do? I must interfere the session timeout to do an
operation. Or i should be able to detemine that the current
request is
the first after a timeout. The way my application currently
crashes is
not acceptable.

I assume that it will work for 2.0.47.or is that the problem here? I can't Find 2.0.43 to download anymore. Also, I'm confused as to why all the other modules in the modules sub directory Have the .so extension. Aren't those unix shared library objects? Can they work On windows?

Choosing an appropriate JK2 Handler
I'm running a configuration with Apache and Tomcat on the same machine. Which handler(s) would I see the biggest performance improvement by using them?

CPU Cache Performance Gain with Tomcat Apache
I realize this question is more related to the JVM implementation and O/S than anything else, but generically speaking how significant of a performance gain would a web/application server combination see (in terms of response time) from a .5MB CPU cache to a 1MB CPU cache. _ Jeremy Nix Senior Application Developer Southwest Financial Ltd.

Help with JK2 and Apache 2.0.47
I'm finding the documentation out on the apache site to be a little slim on JK2. Especially in terms of building the .so/.dll file. Is this code production ready? I'm running an apache (2.0.47) installation and a tomcat (4.1.27) installation on a windows 2000 server machine, communicating over JK. Recently I noticed (after looking in my modjk.log file) that I was receiving the following error with JK: --- [Tue Sep 09 15:25:11 2003] [jk_ajp_common.c (738)]: ERROR: can't receive the response message from tomcat, network problems or tomcat is down. err=-53 [Tue Sep 09 15:25:11 2003] [jk_ajp_common.c (1137)]: Error reading reply from tomcat.

I wanted to try out JK2, since it is suppose to be new and improved, but the documentation really didn't help me figure out where to find the module, or how to build the module...(preferrable the first choice). Anybody out there know what I'm going through that can help me out? _ Jeremy Nix Senior Application Developer Southwest Financial Ltd. [EMAIL PROTECTED] (513) 621-6699 ext 1158
Tomcat Virtual Directory
In IIS it is possible to specify a virtual directory within a given virtual server that maps a directory under the website to a specific directory. Well, I have a need to create this type of functionality for a specific webapp only. So that when you go to Http://localhost/WEB_APP/DIR, then the docBase for that directory will be, in my instance, outside of the webapp directory structure.

Single Tomcat instance mapping to multiple websites
Problem: I have a need to map multiple (3) websites to a single tomcat instance, but different web applications. Reason: For load-balancing/fail-over. I realize that you can install apache as the load-balancer and apache http server can handle the virtual host mapping. But, we are using a piece of hardware as our load-balancer, so the http server is out of the mix. What is left is 2 tomcat instances communicating over the ajp13 protocol. So, is this possible with tomcat? _ Jeremy Nix Senior Application Developer Southwest Financial Ltd. [EMAIL PROTECTED] (513) 621-6699 ext 1158

RE: [beginner question] reloading classes
If you're stopping and starting tomcat and seeing that the change has not been picked up, then you're experiencing a classloader issue where that class is being picked up in a higher classloader before your version of that class is. For instance: TOMCAT_HOME/webapps/your_app/WEB-INF/classes/com/example/MyClass.class TOMCAT_HOME/common/classes/com/example/MyClass.class The 2nd one would be loaded prior to first because it will be loaded in a higher classloader. As for the touching of the web.xml file to reload the class. This only works for classes loaded in the web application's classloader, and not for classes loaded within tomcat's internal classloader. I don't have the specific Tomcat classloader hierarchy on hand, but I can tell you that a change made outside the context of your app to a class loaded within common/lib or server/lib requires a restart of Tomcat. _ Jeremy Nix Senior Application Developer Southwest Financial -Original Message- From: Jacques Capesius [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 21, 2003 12:31 PM To: 'Tomcat' Subject: [beginner question] reloading classes Hi folks, I'm new to Tomcat, but not as new to J2EE. I have a jsp, and I made a change to a class that's being loaded into it as a bean, but I can't get the page to use the new class and not the old one. My question, thus, is: when I make changes to a class, how do I get Tomcat to reload the class? Restarting Tomcat doesn't seem to do the trick. Searching the web, I found a doc that made mention that touching the web.xml file would force the reloading of the class. I tried that and it didn't work. I also read somewhere that going to the application (where the JSPs are) and typing ANT would force the recompile of everything. Still, the old class is being used. I'm storing the class in %catalina_home%/classes/PSQ/. I'm loading it into the jsp by means of the following line of code: jsp:useBean id=psq class=PSQ.PSQ scope=session/ I've made sure there are no other versions of PSQ.class in any other places it might be used, for example, the WEB-INF/classes directory. Thanks for whatever advice you can give, and I apologize if this question has been asked many times before. -jacques :) Jacques Capesius CNT Web Marketing Developer [EMAIL PROTECTED] (763) 268-6749 -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
