How to do some work when a webapp is first loaded
Hi! Perhaps one of the gurus could space a few minutes... I have worked with tomcat quite a bit, but never had to do anythings like this before: I need to do some work (basically get some data from a db and set up a scheduler) once and immediately when my webapp is deployed or redeployed (ideally even before requests to it get served). Is there a neat way to do this? Any clued would be very appreciated. Thanks in advance, Philipp Taprogge - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hi and thanks for the quick replies. QM wrote: -or you could search the archives. ;) Your question comes up regularly. Yes, I should have. I am sorry. I did not imagine my problem was that common... For Tomcat 4.x and later, investigate the ContextListener class. Looks exactly like what I was missing. The app will run in tc5, so no problems there.

Re: Beginner for Apache Tomcat: Need Help
Hi! TK wrote: 1. Can I install and run Apache and Tomcat on the same machine? Or, at the first place, do I need to do so if Tomcat alone can be used as a Web server? Yes, you can and no, you don't have to if your setup does not require it. Often sites use apache for serving static content (due to it's superior performance and security concerns) and let it pass requests to jsps to a tomcat. 2. If I install both of them on the same machine, how do I differentiate the host names? Does http://127.0.0.1/ refers to the Apache or Tomcat server? You might want to familiarize yourself with tcp/ip networking basics. For short, each application running on a host that wants to talk ip allocates a port on that host. You access different ports by appending the port number to the hostname separated by a colon: http://localhost:8080/ In a common setup with apache and tomcat, apache binds port 80 (the standard HTTP port) and passes along jsp requests to tomcat by talking to it on another port, on which tomcat listens. 3. How could I create a virtual link to point from the root directory to another directory located at the other machine or the other disk drive? I am not entirely sure I understand what you mean. In general, all requests go to the apache first and it decides which of them to server from where. If the requests call servlets or jsps, apache just forwards the request to tomcat to serve as it sees fit. 6. Can I used JSP to access MS Access database? If not, what is the recommended DBMS to be used, both in Windows and Linux environments? Since jsps and servlets are (basically) java programs, they can access any database for which a jdbc driver exists. If there is one for access (which is not a DBMS system really...) I do not know. I would not however recommend using access in a live environment. Use a real RDBMS like MySQL, postgresql (if you want OSS) or MS SQL Server, Oracle and the like (if you want commercially supported software).

Programmatically deploying webapps
Hi! I am stuck here :-/ Perhaps anyone could give me a poke in the right direction. What is want to do is this: I am writing an installer for my web application. It is intended to ask the user for hostnames/IP-addresses for tomcat and a db-server, edit the context.xml to reflect the datasource, do some sql initialisation (so far, so good) and then (now that seems tricky) antomatically deploy the (local) war to a remote tomcat instance. It seems possible at least with tc5, since the ant task and the deployer app seem to do exactly this. How can it be archived?

Re: RE : encodeURL / jsessionid
Hi! Jerald Powel wrote: Thanks for that. can you tell me then the purpose of jessionid - (methods encodeURL and getRequestedSessionId)? It seems a bit strange to pass the session around while in the session. As far as I understand, the only purpose of jsessionid and the above methods is to allow clients to keep track of their session id when they are not able to use cookies for one reason or another. Normally, tomcat will set a cookie on login containing the sessionid. That cookie is then presented by the client for each subsequent request for a resource in the given context. If this does not work (for example when the client does not allow cookies to be set or simply does not implement cookies), URL rewriting can be used as an alternative. The client then will append ?jsessionid=whatnot to the URL and tomcat will then recognise the sessionid and remove that parameter before passing on the the webapp. encodeURL() will decide wether the client can use cookies at runtime and of not append the jsessionid parameter. So, if you want your clients to have that option, you have to use that method. As to getRequestedSessonId(), I could only guess why the specs opted to expose the id to the webapp... there might be valid reasons, but it certainly does not hurt.

At first glance, I can't tell you why you get this error, but IMHO you could save yourself a lot of trouble if you used a servlet directly in this case. A JSP is a bad choice here, I think, since a JSP response is presumed to have text (or html rather) content. I think your problem might be that some jsp header information is already sent to the client using the jspwriter when you call the getOutputStream() method. You should decide what you want. If you want the client to display something, send text, if you want to push a file to the client, send bytes, but not both in the same reply. In such cases I use a servlet, that first sends the binary data to the client and then sendRedirect()s the client to a jsp that displays the outcome of the operation.

In most cases this brings a certain amount of tolerance you can't overcome. (For instance, synchronizing with an internet time server imposes a tolerance of a few miliseconds du to network packet delays). Since you will only get accurate readings from withing the application (i.e. tomcat) you will then have to make sure that both OS'es system clocks are equally accurate. (For example System.currentTimeMillis() has a range of up to 50ms on Windows9x systems). That said is it simple to write a small servlet that runs on A and makes a request to B including it's current time. A servlet on B then echos that request back to A and adds it's current time as well. Finally the servlet on A generates some kind of user output containing the measured runtimes.

Also, calling System.gc() is unnecessary in allmost all cases it is used. The VM does a far better job in determining when the gc should run than most programmers could. Only if you know your way around in the internals of the VM and you know that it will not run a gc cycle that would beneficial, you can call System.gc() to politely ask the VM to do so.

Re: Problems finding my JDBC driver for Oracle

From what you are writing, I get the impression that you packed the jdbc driver jar _into_ another jar called classes.jar and placed this second jar in your WEB-INF/lib directory. If this is indeed the case, that's your problem. A setup like this does not work, because the classloader does not see jars inside jars.

In general, it is very advisable to know what a firewall does and how it works before installing one. In general, ZoneAlarm is a (rather simple) packet filter, i.e. a piece of software that examines network packets as they arrive at or depart from the machine and decides on a set of rules to allow or deny them. If you want a so protected machine to run tomcat and access it from beyond the firewall, you need to add a rule that allows requests from external sources directed at port 80 (or whatever you set your tomcat to listen on) on the local machine and also to allow the responses from tomcat to any external host. If you want to use SSL, you will have to allow those request/response-pairs as well. You should, however concider wether you really need a firewall, if your machine is a pure server that does not serve other purposes. In that case, you should just close all ports you don't need. A closed port is no risk and if the listening software has flaws, a firewall wouldn't protect you either.

Re: Connection Reset By Peer
Hi! Ferreira, André wrote: Can someone please explain to me what does Connection reset by peer means? Does it mean the server does not recognize the connection attempt from Tomcat or are there some other explanations. Or is there some port not available...:-(. Since TCP is a connection-less protocol, it uses a three-way handshake to simulate a connection. The client sends a packet with only the SYN bit set, the server replies with a SYN ACK packet and the client acknowledges this with a single ACK. After that, server and client have agreed to act as if they were actually connected to each other and they begin to actually exchange data. If now at any time one of the two sends a packet with the RST (reset) bit set, this indicates that the makeshift connection has been disrupted. This can have many reasons. So, connection reset by peer on one end (e.g. the broswer) means, that the other end (in this case the server) closed the connection for reasons unknown. In this case, the server process is running fine and the port is available as well, the server just wouldn't talk to you. Phil -- And on the seventh day, He exited from append mode.

which uses commons-logging and log4j.
All I do is use the commons' Log and LogFactory in my application and
place a log4j.properties file in my WEB-INF/classes.

course):
log4j.rootCategory=DEBUG, warthoglog

log4j.appender.warthoglog.layout=org.apache.log4j.PatternLayout

log4j.appender.warthoglog.MaxFileSize=2048KB
log4j.appender.warthoglog.MaxBackupIndex=20
log4j.appender.warthoglog.Append=true
This works fine, except that I get not only my application's log
messages but _ALL_ tomcat debug logging in this file, which firstly
slows down my machine (no wonder) and secondly grows the logfile to a
few MBs just from startup.
What the heck am I doing wrong here? This setup worked perfectly in

[WORKAROUND] Re: VERY weird problem with commons-logging and Tomcat5
Hi!
I still do not know what is causing this behavior, but I found a
workaround in case anyone else stumbles upon this problem:
In my log4j.properties I left the log4j.rootCategory property alone
and only set log4j.category.package.name.of.my.classes properties for
each package in my webapp to DEBUG.
This way I only get the DEBUG output of my own classes and not ALL
debug messages generated by the container.
I still wonder why my log4j.properties in /WEB-INF/classes should
reconfigure the container's whole logging mechanism. Either this is a
major bug or tomcat4's doing it right was one.

messages but _ALL_ tomcat debug logging in this file, which firstly
slows down my machine (no wonder) and secondly grows the logfile to a
few MBs just from startup.
What the heck am I doing wrong here? This setup worked perfectly in the
last tomcat4.
Can anyone advice?

Problem with JNDI mail session and SMTP auth
Hello! Sorry if this has already been discussed, I did not find anything usefull in the archive. I am using Tomcat 5 and have configured an SMTP session ressource for my application as described in the JNDI Ressource HowTo. Since I need to authenticate to my SMTP server, I have added parameters mail.smtp.auth, mail.smtp.user and mail.smtp.password to the definition in server.xml. When I try to send mail from my web application using the example code provieded in above howto, I always get an AuthenticationFailed Exception. Is there anything I am not quite getting here? If needed, I can, of course, provide a complete server.xml or other files. Thanks in advance for any help you have to offer.
