Jdeveloper 3.2.3 - Tomcat 5.5 migration: Inordinate delay in JSPs returning XML
I am going nuts trying to figure out why: An application created using Jdeveloper 3.2.3 (on Windows 2000). Some pages send XML as response. When using Jdev, JSP/Web-to-go server everything is fine. Now trying to migrate to TomCat 5.5. For pages that return XML, I am noticing a rather 'hang' like behaviour. As if client is waiting for something: Moreover when using telnet no such problem exists - the response comes boom. (Not sure how to look at header - I do not see any headers in the response in telnet) I put a time stamp at beginning and end of my processing. Elapsed time is 20ms. Page size 500 b. All done locally. Browser (Internet Explorer) takes about 9s to display the XML. Page is buffered (32K, though doesn't help, autoflush on). I even tried with response.SetHeader (Connection, close) no luck. Similarly my (C++) client makes a bunch of call to such JSP pages returning XML. Each time the processing supposed to happen, happens in 20-100ms. But the client seems to be 'waiting': gaps between timestamp for next request spans more than 10-30s. The client uses Microsoft's IXMLHttpRequest (MSXML v3). Any ideas what could be happening? Also any reason for cookies not be written by Tomcat (the Jdev does write that) mucho gracias - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Jdeveloper 3.2.3 - Tomcat 5.5 migration: Inordinate delay in JSPs returning XML
Updates - setting Internet Explorer to use HTTP 1.0 makes the problem go away. I still do not understand why this should happen and what can I do to have the 1.1 mass of clients work with this correctly. Any insights would be much appreciated. FYI - the header seen by the JSP page is: //inase of 1.1 Here are the header Header:accept*/*,Header: ---,Header:user-agentMozill a/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.0.3705),Header:host127.0.0.1:8080,Header:connectionKeep-Alive,Header:cooki eWTGBID=e1ujo01n //incase of 1.0 Header:accept*/*,Header:accept-languageen-us,Header:user-agentMozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.0.3705),Header:hostlocalhost:8080,Header:,Header:cooki eWTGBID=e2jl7opw; _tpc=_t%3D1105675240385%26_l%3D0 Rajeev Singh Intelliplanner Software Systems, Inc. 203-483-4279(O) 203-558-3224(C) www.intelliplanner.com , www.ipssi.com This mail contains proprietary and confidential materials.

Subject: Nightmare with Tomcat 4.1 and SSL configuration
Cosmin I was stuck on the same issue for sometime. Then I realised that I had not put the jsse jar in the classpath. So I copied the 3 jars - jsse.jar, jnet.jar, jcert.jar into %JAVA_HOME%\jre\lib\ext. After that the problem went away. However, I would like to understand how I can configure tomcat to see the logs.

Re: A very weird problem
well we tried this on tomcat running on win9x box and it is getting added(!), in log file you can see adding context /at though docBase points to some bogus location. did u try to stop+start the server after adding these contexts ? Pradeep Kumar wrote: I have got Tomcat 3.2.1 on the Solaris box. I have got a directory called "at" under webapps directory. The problem is that when I start the tomcat server, my context "at" doesn't get loaded (I don't see the message "Adding context Ctx( /at )"). The examples and test context does get loaded. I even tried to put the at directory out of the webapp directory and defined in the context in the server.xml file. But the "at" context doesn't load. The real weird behavior is that, when I rename the test directory to test1, the test context is loaded. I tried all kind of things like, creating a war file of "at", installing tomcat again. But can't fix this problem. Even the log file is not created under logs directory. I am really having very tough time with this, your help here is highly appreciated.

Re: urgent help please
first thing is to check the log files , if it has something like: loaded context /abcd or not.if this context is loaded as per the log files then check the docBase attribute of your context , whether it is pointing to correct physical directory or not. and check for possible case-mismatch also.

passing IIS session variable to stand-alone tomcat
Hi list we have tomcat 3.2 running as a stand-alone service on win NT4.0 m/c. we are also running IIS 4.0 on same m/c.. applications (mostly asp pages) running on IIS use session variables. basically when user logs on to the IIS server for first time, his login id is subsequently used as session -id. now from one asp page on IIS server we have to go to jsp pages running on tomcat. how can we pass the session variable that we are using in asp pages on IIS to jsp pages on tomcat ? on IIS : some asp page using session-id and it has link to one HTML page hosted on tomcat this HTML page is submitted to a jsp page on tomcat now in this jsp page we want the session-id that was being used in asp page. would appreciate ur help -- eagles may soar, but weasels don't get sucked into jet engines -- anonymous psycopath on ./ --- Rajeev Jha Indegene Lifesystems P Ltd. 130, 1st cross , 5th block, kormangla , bang!ore - 95 voice -- +91-80- 55243 14/24 http://www.indegene.com
tomcat and scalability
We are building a large in-house enterprise application, and we are evaluating JSP technology. We are considering what is known as the "JSP Model 2" architecture, where business logic lives in JavaBeans, servlets handle control flow, and presentation is handled by JSP. Are people using JSP for large enterprise applications (as opposed to consumer websites)? Are there any issues to be aware of, if your application will have a thousand or more webpages? For example, will tomcat load all thousand JSP pages (servlets) into memory as they are used, and keep them there (as opposed to discarding them after a while)? Will this cause performance problems because of excessive swapping etc? __ Do You Yahoo!? Yahoo!

Session Tracking Problem
I am having problem in tracking sessions.
On the login jsp page in the application, I used a servlet and created a
session with
HttpSession session = req.getSession(true)
then after sucessful login it goes to the next jsp page say(b)
and passess some variables to this page as a hidden variable.
Then on this page (b) , I used
a href = "%encodeURL(..jsppage)%" and passes the same variable again to
the another page (c).
Then I tried to check the session value on the this page in the servlet with
HttpSession assession = request.getSession(false)
If (assession ! null)
{
..do some processing
}
else
{
Create a session
}
but on checking with getSession(false) it gives null and I could'nt get the
previous session.
Can any body tell where i am doing wrong or is there any other way to do
this

hi list it is possible to use tomcat with IIS and it works fine. things u need to install r the following : 1. jdk1.2.2 / jdk1.3 or some other JVM if u like 2. then install tomcat (binary release is there , so u don't have to do anything) 3. check the stand alone tomcat 4. if u want, u can make jakarta-tomcat a service on ur NT machine 5. now use the isapi_redirect.dll to server jsp pages/particular contexts with IIS 6. tomcat user guide has all the information , and basically on NT u don't have to do much anyway!!
