POST file via Form O'Reilly lib Tomcat problems
I'm having problems trying to upload a file to a servlet. The problem occurs when we use a HTML form to POST a binary to a servlet. Very small files (~100 bytes) work fine but anything above (~350 bytes) throws the exception listed below. Tomcat version is 3.2.1, the server is Red Hat Linux release 7.0, Kernel 2.2.16-22. We are using Jason Hunter's multipart request handling servlets (www.servlets.com/cos). Shifting to 3.2.2 and 3.3-m3 did not resolve the issue. Shifting to Tomcat 4.0-b5 did resolve this problem but raised others (request.getParameter(String) did not function). The problem is listed in the FAQ for Jason Hunter's library (http://www.faqtory.com/servlets/) but the solution seems outdated. Searching the archives for this list gave similar cases of this problem, but no solutions that worked for me. The list commonly suggested that it was a bug with AJP13 and that reverting back to AJP12 will fix. However, I've checked our conf/tomcat.conf file which claims we are using AJP12. Any ideas, work-arounds or feedback will be greatly appreciated. Thanks, Adam. The stack-trace for the exception thrown by Tomcat 3.2.1 is: 2001-06-21 04:08:17 - ContextManager: Error reading request, ignored - java.lang.ArrayIndexOutOfBoundsException at org.apache.tomcat.service.http.HttpRequestAdapter.parseHeaderFiled(HttpRequestAd apter.java:224) at org.apache.tomcat.service.http.HttpRequestAdapter.readHeaders(HttpRequestAdapter .java:205) at org.apache.tomcat.service.http.HttpRequestAdapter.readNextRequest(HttpRequestAda pter.java:140) at org.apache.tomcat.service.http.HttpConnectionHandler.processConnection(HttpConne ctionHandler.java:1 95) at org.apache.tomcat.service.TcpWorkerThread.runIt(PoolTcpEndpoint.java:416) at org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java:498) at java.lang.Thread.run(Thread.java:484)
RE: Problems with ajp13, mod_jk, and load balancer
I'm having problems getting ajp13 working reliably with mod_jk and the load balancer. Here is my configuration: - 4 Sun Solaris Sparc machines with similar setup - Apache 1.3.20 - Tomcat 3.2.2 - mod_jk compiled from Tomcat 3.2.2 source - JDK 1.2.2 - Cisco Local Director sitting in front of Solaris machines, doing load balancing - Running servlet based application which uses HTTP sessions, by use of cookies. On all four machines, I have the Tomcat workers.properties set up to load balance between all four machines, with lbfactor=1 and type=ajp13. The worker names are the same in all four files with the same host. Everything seems to work fine until I click reload on the browser a good 20-25 times when viewing a servlet generated page. My application (which uses HTTP sessions stored on the server) complains about an invalid session (basically it can't find the session information for the session id passed). I turned the prompt for cookies option on in my browser and found that after a good number of clicks, it tries to issue me a new cookie from a different Tomcat! It looks like under heavy load the load balancer tries to send me to a different Tomcat even though the session id contains the worker name (ex. a164gy8s01.www3, where www3 is worker name). I then tried the same test with a Linux machine running Apache 1.3.20 and Tomcat 3.2.2. When clicking heavily, I get a 500 Server error. I noticed in the jk_mod log file, it complains about no workers being available. If I switch from ajp13 to ajp12, everything works fine in both scenarios mentioned above. No 500 server errors or invalid sessions caused by the request going to the wrong Tomcat. Is there a bug in ajp13 or is there some kind of configuration I can tweak? Send us the server.xml and httpd.conf !=) I feel that you have to less java threads available

Re: tomcat, and servlet testing in a multi-user environment

We are several programmers who are programming servlets and jsp on our tomcat server, and each time we modify a servlet or a jsp, we have to restart tomcat so it takes in consideration our changes, and our problem is that we are working everyone from his computer at the same time, so when someone has made some changes and he wants to restart tomcat, it annoys the others who may be testing their servlet. So is there a way to make tomcat aware of new changes without restarting it or should we install a tomcat on everyone's machine ? We have tomcat on everyone's machine - plus a couple of servers. Works fine, with a couple of caveats: 1. We all have our own packages - no namespace conflicts - with a couple of utils packages that everyone can use. 2. Watch for classpath issues - it's real easy to mung your own classpath and then find that the code doesn't work on other machines. Same thing for people downloading code (xerces, xalan etc. libraries) and having different versions. The idea of having an integration server is a great one, especially if you can combine that with a reasonable set of junit/cactus/httpunit tests, and clean builds. But, the flexibility of being able to start/stop your own server is essential IMHO.

TagLib Class Resolution Problem (TomCat 3.2.1)
Whenever I use my taglib from within the subdirectory pages, for example, jasper complains that Class pages.SpecialConnectionTag not found in type declaration.

XML parser: old version
Hi all With Tomcat 3.2.2 RPMS, I got some XML parser. I suspect it is sun's JAXP implementation 1.0. It DOES NOT support namespaces (I found it from the error messages:) so it is not possible to use XSL in JSPs/Beans/servlets. Will it be any problem to use JAXP 1.1? Or Xerces? What is the current policy of using XML parsers in tomcat? Why tomcat does not use Xerces having the same Apache licence? Thanks for any comments Sergey
[POLL] Tomcat 3.x RPMS : Which XML Parser to be put in ? : WAS : XML parser: old version
Hi Sergey, With Tomcat 3.2.2 RPMS, I got some XML parser. I suspect it is sun's JAXP implementation 1.0. It DOES NOT support namespaces (I found it from the error messages:) so it is not possible to use XSL in JSPs/Beans/servlets. That's a known problem. I package these RPMs and asked previously in tomcat-dev which parser used by default. Some proposed crimson, others xerces-j (?). Will it be any problem to use JAXP 1.1? Or Xerces? What is the current policy of using XML parsers in tomcat? Why tomcat does not use Xerces having the same Apache licence? I launch that poll to see if which XML parser RPMS users want to see included by default. I could add xerces-j 1.4.0 or crimson 1.1 (from xml-crimson CVS or from http://xml.apache.org/dist/crimson/crimson-1.1.zip) FYI, I removed on all my sites (which use this RPM), jaxp.jar/parser.jar and used xerces-j instead !
Re: XML parser: old version
Someone said he managed to get Xerces work without too mich bother. He simply wedited the tomcat.bat/tomcat.sh startup script to put the xerces xml parser in the classpath instead of the standard one.

Re: [POLL] Tomcat 3.x RPMS : Which XML Parser to be put in ? : WAS : XML parser: old version
I launch that poll to see if which XML parser RPMS users want to see included by default. Probably no XML parser should be included. . Just document the fact that admin should synlink necessary jars to the tomcat lib directory. IMHO it is wrong idea to include parser with any java app which requires it.

JAXP API makes this unnecessary (definitely unless Tomcat uses some special private API from crimson or xerces). If I didn't include a default XML parser, we'll receive just too many emails from new users telling about 'tomcat couldn't find XML parser'. The XML parser should be included in the distro since new and average users MAY never use XML in their apps. The experienced users in XML known what is JAXP, NAMESPACE, and also know what parser they want to be used. Note that with TC 3.3/4.0 you'll could use a different parser... The real question is what could be a reasonable choice as XML for Tomcat (size, functionnalities, stability...) I'll forward the POLL to general-xml and general-jakarta !:

tip for users connecting over SSH to their tomcat server
For tomcat users who log in to their Unix servers over SSH: ssh 2.9 has a bug where if you have any background processes running, on logout your SSH will hang. Adding nohup to tomcat.sh, just before the calls to $JAVACMD will alleviate this, but will also leave the file nohup.out in the dir you start tomcat.sh from: nohup $JAVACMD... - stephan Generic Universal Computer Guy [EMAIL PROTECTED] - http://www.einsurance.de Office: +49 (89) 552 92 862 Handy: +49 (179) 211 97 67 ...control is a degree of inhibition, and a system which is perfectly inhibited is completely frozen. -- Alan W.

RE: application error
First, I would suggest that you post using plain text messages, more people will be able to read your message, which is what you want, right? Second, I believe that you have fallen victim to the JDBC-ODBC Bridge threading problem. From your message I believe that you are using Windows (application error) with ODBC (dsn). This combination does not allow concurrent access to the data source. This is a bug in the bridge and you can find out more about it in Sun's Bug Parade, but the short version is the Bridge is experimental and un-supported. You can either try and make your Database requests one at a time (which has performance implications) or you can find other drivers - there are free type 4 JDBC drivers for mysql.

RE: POST file via Form O'Reilly lib Tomcat problems
Unfortunately I don't have an answer as to why you can't upload, but I can give you a little information that might help you. First, when using Jason Hunter's library, request.getParameter won't work. His library reads the entire posting and then provides methods to get the parameters back. So Tomcat 4m5 might work. Second, you are not running Tomcat behind Apache or any other web server. Therefore, you are not using AJP13 or AJP12. You are using HTTP as your protocol (as the stack trace lists). I am using Tomcat 3.2.1 to receive binary files (on the order of 100K - 1M, Excel and Access files) without any problems over HTTP. If this request if coming from a program, I would look at how its building the headers, because that is where the problem is (readHeaders). Otherwise, I don't think I can be of much help.

Sir , We are facing a problem related with session variables. Our site consists of .jsp , .html files.Once we login to the site two session variables are created TimeSpent,Login. All pages from that are browsed after checks for session variable. So if session variable is 'null' , it will not allow to browse through other pages.These thing are working properly. In our site we have an other option which is 'Search',which will query keywords from the sites content and provide links to those pages. The links which the 'Search'(which is a SERVELT : SearchServlet) returned are actual links to .jsp pages,( which was accessed earlier) was not able to access by click on the link returned by 'SearchServlet' The links returned are having links to the same .jsp pages. Sir, Is it because the session being removed , when we redirect from a Servlets dynamic output or due to some other reasons. The following error is obtained when we click on the link which was returned by SearchServlet. SearchServlet actually returns : path to the '.jsp' file.

Runaway Thread Problem
I have searched through the archives and have found several people with this problem, but nothing that seems to fix it. Any help would be appreciated... We are running Apache 1.3.19, Tomcat 3.2.2, mod_jk, ajp13. After a day or so with a user load, our thread count continues to climb and threads are not released. We are running PoolTcpConnector and have made sure that threads are being released on our development site. We have a script that monitors the threads every hour and they seem to just increment throughout the day and are never released. Once the thread count reaches the 500 point, Tomcat stops responding. The apache server continues to accept requests once Tomcat stops. Once we restart Tomcat, the process cycles through again. Along with the thread count increasing, memory usage climbs until there is 5-10 MB free. We have moved the max threads value from 50-75-150-200 which didn't change the symptoms. We move the session timeout in WEB-INF/web.xml to 5 with no help. We have tried simulating the user load on our development environment but the thread count returns back to a normal level after letting it idle for a few minutes. I'm guessing we have issues in our application but have not been able to uncover them so far. Again thanks for any insight into the problem.

Re: [POLL] Tomcat 3.x RPMS : Which XML Parser to be put in ? : WAS : XML parser: old version
The XML parser should be included in the distro since new and average users MAY never use XML in their apps. OK. My vote is for xerces (it is good and has same licence). Also, it would be good to have the list of tomcat-compatible parsers. At the moment, I tried jaxp 1.1 and latest xerces - they work correct. What about people using IBM's one? MS's one? BTW, for new and average users it is possible to use RPM dependancies. For example, ask xerces (and sun's) people to put their classes to parser.jar and check for this jar in RPM.

Hi- I've deployed an application with Tomcat at the root (i.e. /). At one point I load a resource file with the command: InputStream is = getClass().getResourceAsStream(/app.properties); But Tomcat throws an exception here if the file app.properties is in the /WEB-INF/classes directory. If I copy it into a directory that is in the default CLASSPATH, then it works fine. Isn't the WEB-INF/classes directory for each deployed application automatically added to the Tomcat classpath? Is the behavior I'm seeing the expected behavior? I hope I'm just doing something thick... otherwise, its more problematic to be able to bundle up an application, because the resource files would need to be copied somewhere else. Any advice? BTW Tomcat 3.2.2 on Win2k, no web server (i.e. Tomcat default, port 8080). Thanks! -Richard
RE: [POLL] Tomcat 3.x RPMS : Which XML Parser to be put in ? : WAS : XML parser: old version
The XML parser should be included in the distro since new and average users MAY never use XML in their apps. OK. My vote is for xerces (it is good and has same licence). Also, it would be good to have the list of tomcat-compatible parsers. At the moment, I tried jaxp 1.1 and latest xerces - they work correct. What about people using IBM's one? MS's one? IBM xml4j is at 99% xerces-j Did MS got a jav parser ? BTW, for new and average users it is possible to use RPM dependancies. I started think at this that's why my latest xerces-j RPM have a : Provides jaxp 1.1 May be next release For example, ask xerces (and sun's) people to put their classes to parser.jar and check for this jar in RPM. Another option, RPM pre-install script could try to find existing parser (and fail if there is no one). RPM is rather sophisticated mechanism to deal with this problem... The build process of RPM allready deal with installed parser (jaxp 1.0/xerces-j) may be next time crimson. I could add such system at install time but what to do when a user got at the same time, crimson and xerces-j ??? Regards, Sergey
Re: distributable servlet in Tomcat3.2
Hello,
Sorry for the first mail I sent. I realize now that I
completly misunderstood what distributable is.
I realized it thanks to this link:

And then better understood the Servlet Spec and these
2 links:

Hello,
I've read on this list that Tomcat 3.2 supports
serializing sessions attributes. I wanted to try it,
but could not find more information on the subject
here. So I tried to do it according to the servlet
2.2
specification. As it is not working, I try to sum-up
here what I've done:
I have installed 2 Tomcat 3.2 on the same machine
(taking care that the 2nd Tomcat starts on port
8081),
and for each of them, I have built a very simple
session webapp :
- session/
- WEB-APP/
web.xml
- classes/
SessionServlet.class
The web.xml looks like:
?xml version=1.0 encoding=ISO-8859-1?
!DOCTYPE web-app

Application 2.2//EN
http://java.sun.com/j2ee/dtds/web-app_2_2.dtd;

servlet-classSessionServlet/servlet-class
/servlet
servlet-mapping
servlet-namesession/servlet-name
url-pattern/session/url-pattern
/servlet-mapping
/web-app
For the firt Tomcat, I compiled:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class SessionServlet extends HttpServlet {
public void doGet (HttpServletRequest req,
HttpServletResponse res)
throws ServletException, IOException
{
ServletOutputStream out = res.getOutputStream();
res.setContentType(text/plain);
out.println(SessionServlet 1 output);
ServletContext servletContext =
this.getServletContext();
servletContext.setAttribute(foo,abcdef..foo);
out.println(attribute foo, with value
abcde...foo, added in ServletContext);
HttpSession httpSession = req.getSession();
httpSession.setAttribute(bar,abcde...bar);
out.println(attribute bar, with value
abcde...bar, added in HttpSession);
out.close();
}
}
For the second Tomcat, I compiled:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class SessionServlet extends HttpServlet {
public void doGet (HttpServletRequest req,
HttpServletResponse res)
throws ServletException, IOException
{
ServletOutputStream out = res.getOutputStream();
res.setContentType(text/plain);
out.println(SessionServlet 2 Output);
ServletContext servletContext =
this.getServletContext();
String foo = (String)
servletContext.getAttribute(foo);
out.println(foo=+ foo + (get from
ServletContext));
HttpSession httpSession = req.getSession();
String bar = (String)
httpSession.getAttribute(bar);
out.println(bar=+ bar + (get from
HttpSession));
out.close();
}
}
Requesting respectively the first servlet, and the
second serlvet did not give the expected results:
http://127.0.0.1:8080/session/servlet/SessionServlet
SessionServlet 1 output
attribute foo, with value abcde...foo, added in
ServletContext
attribute bar, with value abcde...bar, added in

http://127.0.0.1:8081/session/servlet/SessionServlet
SessionServlet 2 Output
foo=null (get from ServletContext)
bar=null (get from HttpSession)

is
it simply not possible to do it ?

Tomcat not putting session objects into JSP page context?
Hi all- I've got a JSP/Javabean application that
works fine under JRun and iPlanet Web Server. However, when I use Tomcat,
it does not seem to be instantiating new session variables if they don't already
exist. In the top of my JSP page, I have:
jsp:useBean id="loginBean" class="LoginBean"
scope="session"/
And further down in the page I do (actually inside
a TagLib, but I tried it in the page as well as a test):
Object obj =
pageContext.getAttribute("loginBean");
But obj comes back as null. If
Itry:
LoginBean tlb = (LoginBean)
session.getAttribute("loginBean");
then I get the bean! Why is my call to
pageContext failing to get loginBean, especially considering that this works on
other Java application servers?
Thanks for any help!
Best regards,
Richard
JkMount in httpd.conf
Hello... I'm using Apache with mod_jk and Tomcat for jsps and servlets. JSP is without problem, but servlet don't want to run. Because informations about absolute path of requested document is written to terminal, where Tomcat was started, I found out that servlet (URI: http://poseidon.bgs.sk:/intranet/WEB-INF/classes/Hello) is not translated from relative to absolute path - nothing apears on terminal. I think, that Apache don't redirect this request to Tomcat (or appropriate worker)... my httpd.conf has this section: VirtualHost poseidon.bgs.sk: ServerAdmin [EMAIL PROTECTED] DocumentRoot /export/home/virgo/web-data Location /export/home/virgo/web-data Options Indexes FollowSymLinks AllowOverride None SetHandler default-handler Order allow,deny Allow from all /Location ServerName poseidon.bgs.sk JkMount /*.jsp virgo JkMount /intranet/* virgo ErrorLog /opt/oracle/ias/product/8.1.7/Apache/Apache/logs/error_log TransferLog /opt/oracle/ias/product/8.1.7/Apache/Apache/logs/access_ log /VirtualHost *.jsp works good, but second JkMount not... I tried many versions of second field of that line - but nothing. Always 404 Forbidden (Apache signed on the bottom of page ;-))...

RE: getResourceAsStream doesn't find files in WEB-INF/classes
The question is - what class loader loaded the class this is being
called from? The getClass().getResourceAsStream doesn't magically know
about resources that are not loaded with its own classloader or one of its
parents. So, app.properties and the class that you are trying to load this
from must be loaded from the same classloader, which means that they both
must either be in the CLASSPATH, or the %TOMCAT_HOME/{lib|classes}, or
WEB-INF/{lib/classes}. If the class is higher up in the classpath then it
won't be able to find the properties file.

Tomcat 3.2.2: wrong charset (always UTF8) when creating .java from .jsp
I have two instances of Tomcat 3.2.2, one running under Windows NT, the other running under Linux. The problem is identical in the two. No matter what character set I use when saving my JSP files to disk, Tomcat always assumes that they're in UTF8 format. When I activate DEBUG logging for jasper.log, the following entry always appears when compiling a class: Compiling with: -encoding UTF8 ... (the ... refers to other command-line parameters, such as -classpath). This has some unfortunate side effects: 1./ If I save my file as UTF-16, no JSP tags are recognised are the resulting file is supplied as-is to the browser. I've looked at the .java file that Tomcat creates, and it creates lines such as : out.write(ÿþ % @ p a g e l a n g u a g e = \ j a v a \ % \r\n % ! \r\n s t a t i c i n t h i t s = 0 ; \r\n % \r\n h t m l \r\n h e a d \r\n t i t l e J S P E x a m p l e / t i t l e \r\n / h e a d \r\n b o d y \r\n \r\n h 1 J S P E x a m p l e / h 1 \r\n \r\n p H i t c o u n t :% = + + h i t s %Ãé x / p \r\n \r\n / b o d y \r\n / h t m l ); 2./ All accented characters are shown up as é or similar (instead of é). This has nothing to do with the %@page contentType % directive, as that's handled correctly. It's the creation of the .java file which goes wrong. Is this a known bug? Any workarounds? Never seemed to have this problem running the same code under Tomcat 3.2.1... -Chris

Problems using Jikes as compiler
I've successfully specified Jikes as the Java compiler for the jsp servlet under Tomcat 3.2.2 with Windows NT. However, I can't get Tomcat to use JIKESPATH instead of CLASSPATH when compiling, as the JspCompilerPlugin supplied with Tomcat passes the -classpath param to Jikes, consequently overriding JIKESPATH. As a result, Jikes no longer finds rt.jar, so it can't compile anything (as it can't find java.lang.* ..!). I've correctly setup the environment variables for normal use. So at MS-DOS, I can type: C:\classes jikes Hello.java However, if I type: C:\classes jikes -classpath . Hello.java ... it doesn't work, as JIKESPATH is overridden. Looking at jasper.log, I see that Tomcat takes the second option, so JIKESPATH isn't taken into account. How can I get around this? Thanks, -Chris
problems runing jsp examples which come with Tomcat3.2.2
Dear all, I have installed Tomcat3.2.2 on a Solaris 8 system with jdk1.3. I can run all the servlet examples, but I get java.lang.NoSuchMethodError exception when I try to run any of the jsp examples. The followings is what I get when I try to run 'date.jsp'.

Help! strange bahavior when opening url with JSESSIONID explicitly set
Hi all, My environment: Solaris 8 Tomcat 3.2.2 jdk1.2 I have a need to open URLs on tomcat from within my code. I have done this successfully with JServ, no problem To do this with Tomcat, I just changed the cookie to JSESSIONID. After setting the cookie and posting the post data, I call URLConnection.getInputStream(). At this point 2 things happen: - The method call never returns - Tomcat spins out of control, refusing to answer any requests Any suggestions would be *much* appreciated, I am banging my head against the wall right now. I have tried to encode the session id as ;jsessionid=sessionid on the URL string to see if GET would work where POST was not - no difference. Thanks, naeem

session timeout handling
When a Tomcat session times out does it send you to a preset error page? What is the mechanism there? What is the best way to handle timed out users?
RE: session timeout handling
When a Tomcat session times out does it send you to a preset error page? No. not unless you throw an exception due to dependence on something from session. You could develop an entire webapp without ever using the session and despite the fact you never use it it will still be instantiated. For obvious reasons. What is the mechanism there? No mechanism! What is the best way to handle timed out users? Depends. Do you have a security concern(if so you should be implementing Realms of some sort which manage the session timeout for you)? Are you requiring something to exist in the session for certain portions of your app? ...

RE: session timeout handling
Title: RE: session timeout handling Timeout will not send anyone anywhere. When the session expires it cleans up all the objects in the session's attributes. If the objects are of type HttpSessionBindingListener then an event is thrown against them. The best way to handle timed out users is to attach an object of HttpSessionBindingListener to their session, When that object recieves the unbound event do whatever is needed to be done to clean up. Note - (I got burned on this) at the unbound event the session object no longer references any attributes (or maybe it is just some) so the object of the above type should have enough intelligence in it to handle the actions you want to perform at the end. for example you had a session attribute storing the logged in user name, dont expect that attribute to be available after the unbound event. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Friday, June 22, 2001 3:51 PM To: [EMAIL PROTECTED] Subject: session timeout handling When a Tomcat session times out does it send you to a preset error page?

What is the best way to handle timed out users?
Hi :-) I suggest you make a object witch implements
javax.servlet.http.HttpSessionBindingListener, and put object into a session
by setAttibute(...), then:
- when that object is bounded into session, valueBound(...) will be
called
by container
- when the session is timeout/inValidate(...), that object will be
unbounded,
then valueUnbound(...) will be called by container
the following is a sample code from Servlet-List:
class CleanUp implements HttpSessionBindingListener{
private String name;
public CleanUp(String name){
this.name = name;
}
public void valueBound(HttpSessionBindingEvent evt){
System.out.println(in CleanUp, valueBound..., name=+name);
}
public void valueUnbound(HttpSessionBindingEvent evt){
System.out.println(in CleanUp, valueUnBound..., name=+name);
}
}
in MyServlet:
...
session.setAttribute( Cleaner, new CleanUp(...) );
...
*
- if CleanUp.class is in WEB-INF/classes or in a jar file in WEB-INF/lib,
it will be loaded by WebappClassloader
- if CleanUp.class is in TOMCAT_HOME/classes or in a jar file in
TOMCAT_HOME/lib, it will be loaded by SharedClassloader

RE: session timeout handling
We carry a userid and a shopping cart in the session thu out the app. If the user goes to lunch and comes back, we would like to give them sort of friendly error if their session times out. Allowing the garbage collector(unless you are REALLY nitpicky about knowing that errant Objects are being gc immediately) to manage the cleaning up of these session objects is probably a best practice in most cases. This is why I would suggest a Realm for most cases instead of a implementation of HttpSessionBindingListener(no reason to reinvent the wheel/pull out the sledge hammer to swat a fly) but the idea that you want a friendly error on timeout makes me want to say that a Listener is probably your best bet. If you are new to the Model-View-Control theory Listeners can be kind of daunting to begin with but I would suggest picking up a good java book if this is the case. The problem with implementing with Realms in you case is, if you were to use FORM AUTH TYPE, how to determine whether a user is making their initial login or are in the timeout scenario. The idea in the post below regarding the refresh meta tag is also a possible solution and you could make it even more ingenious and do something with javascript possibly with timers and configure a timer for some time n timeout time that would do something like pop up a warning stating You will be automatically timed out in x minutes Since this is client side it will not cause a request to the server to reset the timeout. www.bankofamerica.com does something similar to this for their online banking I believe. Just a couple of possibilities. --- Michael Wentzel Software Developer Software As We Think - http://www.aswethink.com
Re: JDK CLASSPATH vs TOMCAT CLASSPATH
Hi Again, No one got back to me but I did learn a few things today: 1. No need to tell the system class path about the WEB-INF area. All I need to do is compile from WEB-INF/classes and JDK finds all of my custom packages. This is b/c by default . is added to JDK's path. 2. I think I know why TOMCAT can't find my classes. That's b/c I do not have a /WEB-INF/lib folder. I think this folder should contain the webapp class loader among other things. When I installed TOMCAT 3.2.1 out of the box - the examples webapp did not have a /WEB-INF/lib folder (unless I accidentally deleted it!). Question: Where do I download the required files for the /WEB-INF/lib folder? Or do I have to build them? Dennis Dennis Murphy wrote: Hi, I'm new to JSP. I desire to use the class reloadable=YES feature in TOMCAT so that I can develop my JAVA BEANS and quickly test them without restarting TOMCAT for every little change. I believe that the reloadable feature will not work if I inform the system CLASSPATH where my JSP application classes are located. The reason for this is that the once the SYSTEM CLASS LOADER loads my classes the TOMCAT CLASSLOADER has no control and is unable to unload/reload my classes. Okay if I'm right on my understanding of this, then how do you setup a development environment. In order for me to compile my JAVA BEANS using JDK javac, I must tell JDK where my classes are located in the SYSTEM CLASS PATH ... else it won't be able to pickup my custom packages that are part of my application. So is this like a trade-off? Compile JAVA BEANS or use the TOMCAT class reloading feature - but not both? Can someone please shed some light on how one should setup a development environment? I would like to have the ability to compile and then test with tomcat configured to reload classes. Thank you, Dennis

jsp:include question - weird URL with ..
Hi, I have a question about using jsp:include. I have a relative URL that has a .. in it. jsp:include page=afx_2001_05_25_ANL_5310-1539-NEW.ECO.CBK.ANL.USA...html flush=true / What's weird is that the html file doesn't get included when viewing the jsp page. Nor does it generate any errors, it's just simply ignored and the contents of the html file don't show up when viewing the JSP file. But, if I view the file normally, not going through the jsp:include, and just point my browser directly to the html file itself it works fine. The problem seems to be linked to the .. before the .html because when I remove it it works fine, but unfortunately these file names are generated and I can't get around having the .. in it. Any help would be greatly appreciated! Thanks, Christian Cabanero

Hi Corey, FYI, that is the way the header has been misspelt in the HTTP RFCs one thing to note that i discovered the hard way.. referrer should be spelled as so: request.getHeader(referer) not sure why... but i beat my head against the wall for an hour... until i tried the alternate spelling...

Ports for Workers
Could anyone advise me (or point to a resource) on the ports that are available for use by Tomcat workers in the workers.properties file? We start a number of Tomcat instances, one for each web application we run on our server. We are currently using ports: 8007 8009 8011 8013 8103 We run Tomcat 3.2.1 and Apache 1.3.6 on Linux 2.2.16. We use mod_jk with ajp13 connectors. Unfortunately, I really don't know why we use the ports we do, and which I should or shouldn't use. Any advice most welcome by this newbie! MTIA, Max Hugen
Re: JDK CLASSPATH vs TOMCAT CLASSPATH
Hey There! I did learn more stuff. What had happened is that along the way I explicitly added WEB-INF/classes to my TOMCAT path in my tomcat.bat file. I figured this would be harmless. But I guess it does effect CLASS RELOADING. Therefore, I found if you want CLASS RELOADING to work DO NOT place your WEB-INF/classes path in the system CLASSPATH or explicitly in the TOMCAT_CLASSPATH. Wow! I took me all day to get this working :-( Dennis Dennis Murphy wrote: Hi Again, No one got back to me but I did learn a few things today: 1. No need to tell the system class path about the WEB-INF area. All I need to do is compile from WEB-INF/classes and JDK finds all of my custom packages. This is b/c by default . is added to JDK's path. 2. I think I know why TOMCAT can't find my classes. That's b/c I do not have a /WEB-INF/lib folder. I think this folder should contain the webapp class loader among other things. When I installed TOMCAT 3.2.1 out of the box - the examples webapp did not have a /WEB-INF/lib folder (unless I accidentally deleted it!). Question: Where do I download the required files for the /WEB-INF/lib folder? Or do I have to build them? Dennis Dennis Murphy wrote: Hi, I'm new to JSP. I desire to use the class reloadable=YES feature in TOMCAT so that I can develop my JAVA BEANS and quickly test them without restarting TOMCAT for every little change. I believe that the reloadable feature will not work if I inform the system CLASSPATH where my JSP application classes are located. The reason for this is that the once the SYSTEM CLASS LOADER loads my classes the TOMCAT CLASSLOADER has no control and is unable to unload/reload my classes. Okay if I'm right on my understanding of this, then how do you setup a development environment. In order for me to compile my JAVA BEANS using JDK javac, I must tell JDK where my classes are located in the SYSTEM CLASS PATH ... else it won't be able to pickup my custom packages that are part of my application. So is this like a trade-off? Compile JAVA BEANS or use the TOMCAT class reloading feature - but not both? Can someone please shed some light on how one should setup a development environment? I would like to have the ability to compile and then test with tomcat configured to reload classes. Thank you, Dennis

mod_jk problem...
hii all, I am trying to integrate tomcat 3.3 with apache 1.3.19, and I am using mod_jk on a Red hat 6.2. I have build apache from source. While trying to restart apache I get the following error. Syntax error on line 1 mod_jk.conf: Invalid command 'LoadModule', perhaps mis-spelled or defined by a module not included in the server configuration apache/bin/apachectl restart: httpd could not be started can some one please give me any hints on what can be done to resolve the problem ? Do I need to build apache again ? with some directive which includes mod_jk module.

RE: Context loading of .properties files
For every context make an Entry into your web.xml and add a servlet which loads on start up. The each servlet loads your properties file. and Use URL mapping, to load the appropirate servlet. HTH, Shuklix -Original Message- From: Bryan Connor [mailto:[EMAIL PROTECTED]] Sent: Tuesday, May 22, 2001 8:36 PM To: [EMAIL PROTECTED] Subject: Re: Context loading of .properties files Here is another way to thinkabout it... Create a config table in your database that holds all the properties you need to run your app. One record for each context - the key will be the different URL each context uses. On startup, use the URL to hit the database for the record with the correct properties and go from there. Keep everything in the database. Bryan [EMAIL PROTECTED] wrote: I have several contexts which use a .properties file for configuration. I need each context to have its own version of that configuration file. Is there a way to load properties files based on context? I am looking for a way to load properties files that is similar to the way in which class and lib files are loaded by the servlet class loader. Ideally, the properties files would be automatically loaded from some place under the WEB-INF directory of a given contest.
