war files. (tomcat 4.0 beta 7)
I have packaged my web application in a .war file and deployed it using tomcat 4.0 beta 7. perfect. The only way I could get it to work was to copy my database jar files into web-inf\lib, this would make my war file platform dependent as most database vendors ship different jars for each operating system. I tried them in the %CATALINA_HOME%\lib but that did not help. suggestions / recommendations.

Re: Antwort: Re: what are war files?
They are simply a way of bundling up a context. If you are developing a context "mycontext" and it sits in $TOMCAT_HOME/webapps/mycontext, then to make a war file all you need to do is: cd $TOMCAT_HOME/webapps/mycontext jar -cf ../mycontext.war * and you would have a war file that you could theoretically deploy in any servlet container. This assumes that you have all the classes you need in mycontext/lib/*.jar or mycontext/classes - which IMHO is what you should be doing anyway. cheers dim On Tue, 14 Aug 2001 [EMAIL PROTECTED] wrote: > i am developing jsp sites, but i never had to use war files. do i need them > really - what is the function of that files? > > greets > > bastian > > > -- >Externe MailDmitri Colebatch <[EMAIL PROTECTED]> >14.08.200108:58 > -- > > > > > An: [EMAIL PROTECTED] > cc: > > Thema:Re: what are war files? > > a jar file containing the directory structure: > > /WEB-INF/ > /WEB-INF/web.xml > /WEB-INF/classes/ > /WEB-INF/lib/ > > and named .war instead of .jar > > compare examples.war (jar -tf examples.war) with the examples directory > inside webapps in the install. > > hth > dim > > On Tue, 14 Aug 2001 [EMAIL PROTECTED] wrote: > > > sorry for that question, but i dont know it > > > > thx > > > > bastian > > > > > > > > > > >

It's a little of putting the cart before the horse by attempting to control the number of requests. If the requests exceed the capacity of your web server the worst that happens is the excess requests get things like 404's (I think). But an Oracle server crashing means you probably have aspect of it's configuration set too low. Trying to solve the problem by some how limiting the requests doesn't sound like the optimal solution to me. You may be running the server with default settings. Look at the config file and up whatever it is that deals with connections to the data base and threads. I used to know but its been a long time.

Well, yes, it can attack an Apache server all it wants, the good thing is that this vulnerability doesn't exist on Apache. The worst that happens is that your poor Apache server has to continually attempt to service requests for a resource it doesn't have.

Control the number of request's
Hello all. Can anyone explain me (and to all people of the list) how control the number of request that one client can do? I'm using Tomcat 3.2.3 and if one client with IE or NN push Reload several times, my server does one connection to the DataBase in all the requests. Then, the Oracle 8i crash becouse the other server creates several process, one per thread of the session of the Tomcat. I would like to respond only the last request, and cancel the previous one. Is it possible with Tomcat? And another question, are there any way to call a method of a servlet periodicaly from the server? I would like to clean several objets that are in the httpsession.

RE: unable to instantiate LoginConfiguration while using jaas in servlet
Hi, Charlie, Thanks for the reply. I had AllPermission set on jaas.jar. It's not because of the permissions, but we have solved the problem. It seems to be a known problem in the servlet world. The problem lies in the behavior of jaas loading LoginModule, and LoginConfiguration objects. It only looks on the system classpath. Therefore any LoginModule or LoginConfiguration objects that lives in servlets (which are loaded by the servlet container's custom loader) will not be found, hence the error. The error is not very descriptive (class not found, or file not found, what load it's using?), so it took us a while to figure it out. I also read this limitation will be lifted in 1.4.

RE: Connection reset by peer: socket write error NOT harmless
Just to give you some more background info(you being the kind hearted soul
who read my last post) The image is ALWAYS corrupted if I run the client
program from another machine on our local network.
Also, if I add the following line of code to the servlet:
out.flush();
sandwiched between:
out.write(b);
out.close();
I get a much more robust error, namely:
java.net.SocketException: Connection reset by peer: socket write error
at java.net.SocketOutputStream.socketWrite(Native Method)
at java.net.SocketOutputStream.write(SocketOutputStream.java:83)
Thanks again .

Hello List!
This is my first post here, so sorry for the length.
I'm running a binary distribution of tomcat 3.2.3 on Windows NT, developing
in JDDeveloper 3.2.2.
I have a client java program which sends a simple SQL string to a servlet
which gets an image from our database and returns it. No browsers involved.
The problem I'm having is that a third of the time when I execute the client
request from my computer to the local IP address of tomcat, also running on
my computer, tomcat gives this error message:
2001-08-13 15:39:03 - Ctx( /databasefetcher ): IOException in:
( /databasefetcher + /servlet/databasefetcher + null) Connection reset by
peer: socket write error
And the file, which the client program writes to the file system, is
corrupted.
If tomcat does not give this error message, the image is fine and can be
opened and enjoyed for all of its beauty.
The images are tiffs and are about 250K in size each. Below is the code for
the fetching:
+
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException,
IOException{
//read in the SQL string
BufferedReader br = new BufferedReader(new
InputStreamReader(req.getInputStream()));

if(rs.next()){
isImg = rs.getBinaryStream(1);
}
//set the length to 1.3 mb, the largest image size
res.setContentLength(130);
res.setContentType("image/tif");
res.setBufferSize(130);
byte[] b = new byte[130];
//read the image into the inputstream
isImg.read( b );
//get the servlet output stream
ServletOutputStream out = res.getOutputStream();
//write the image to the response
out.write(b);
out.close();
}
catch(Exception e){
e.printStackTrace();
}
}
AND here is the code for the client program:
++
import java.net.*;
import java.io.*;
import org.xml.sax.*;
import java.util.Properties;
public class StringHttp {
// POST an XML document to a Service's URL, Returning XML document

// (1) Open an HTTP connection to the target URL
HttpURLConnection conn = (HttpURLConnection)target.openConnection();

// (2) Use HTTP POST
conn.setRequestMethod("POST");
// (3) Indicate that the content type is plain text with appropriate
MIME type
conn.setRequestProperty("Content-type","text/plain");

Re: Apache Tomcat mod_jk
You need to do some reading. Usually, apache runs on port 80 Usually, tomcat web server runs on port 8080 (of course, you can change it) If you get to Tomcat via apache, you should be able to do http://my.machine/examples and see tomcat examples. If you do not see them, your connector (mod_jk) is not configured correctly. If you get to Tomcat directly, you should be able to do http://my.machine:8080/examples If your apache is not running, you still can see pages via Tomcat 8080 port, since Tomcat is also a web server. You can disable prot 8080 in tomcat (comment out the connector which has 8080 in server.xml), but until you do, your tomcat is serving pages on port 8080 without apache. When you do ps -ef | grep httpd you see Apache when you do ps -ef | grep java | grep -i tomcat you will see tomcat processes (and threads) If you installed apache from the CD or red hat or whatever, it is automatically started on book. To stop it you need to do: /etc/rc.d/init.d/httpd stop and to start it, you need to do /etc/rc.d/init.d/httpd start On Fri, 13 Jul 2001, Saadat Ahmed wrote: > Another basic question. > > When I kill all httpds and hence my apache server is not running and then I > start tomcat, how come I can browse the tomcat index page on port 8080 > eventhough the apache server is not running. > > Is TomCat more than a Servlet engine, how is the httpd request is being > processed without me having apache running. > > For some reason when I executed "ps -e | grep "httpd" " I do see httpds. > > Is this apache, if it is then how come it starts eventhough I just started > tomcat with startup.sh > > Regards, > > Saaat. > > > _ > Do You Yahoo!? > Get your free @yahoo.com address at http://mail.yahoo.com > Jan K.

I use jave just about the exact same configuration and I don't have the problems you state. I have noticed that if I restart tomcat *without* restarting apache, there are problems.

I've seen a number of posts on this subject and the answer always seems to
have to do with IE. I'm not using it. Though sometimes IIS starts up
acidentally, cutting apache out of the loop.
Any help is greatly appreciated.

There is nothing in the servlet API that lets you (portably) ask for all
the roles assigned to the authenticated user. However, you can ask "does
this user have role FOO" by calling request.isUserInRole("FOO").
If you need to do more than that (for example, you're writing a web app to
administer the set of valid users and roles), your best bet is to write a
database maintenance application in the usual way that happens to point at
the same database tables. From the *application* developer's point of
view, JDBCRealm is not visible -- it just happens to be the gadget that
Tomcat uses internally to look up users and roles in a database.

Apache+Tomcat+SSL+IE5.5
Hi, I have a web server with Apache (with SSL) + Tomcat (with ajp13) Tomcat don't have a HTTP connector. My application only use JSP-servlets(no static page). It work perfectly with IE5.0 , Netscape 4 or Netscape 6 When I use IE5.5 to connect to my apache i have this message from IE : (i have a french message, so it is my translation ) "this page have secure elements and non-secure elements Would you like view the non-secure elements ?" It's just a warning message but I would like to know if : _ IE5.5 is right (they are non-secured element in my JSP pages) or if it is a bug. How to be sure ? _ if yes, Does It mean apache-SSL don't crypt my tomcat's JSP. (i have the same message when i use ajp12 or ajp13 ) Thanks in advance Fred

Re: Restarting Tomcat/Apache
You have to have the ajp12 instantiated in server.xml file just for shutdown, even if you do not use it in workers.properties Just copy the ajp13 connector stuff and change ajp12 -> ajp13 It usually helps...

apache and tomcat
I constantly have about 30 TIME-WAIT connections between the apache and tomcat ports on my localhost. I am wandering if this is normal and if not how to get around it. I also notice that my mod_jk.log file fills up with this error; [jk_ajp12_worker.c (596)]: ajpv12_handle_response, error writing back to server could these be connected? perhaps sockets used up in TIME-WAIT and then the error? any advice is much appreciated.

Getting *original* request path
How do I get the original request URI or path after a page has been forwarded using pageContext.forward()? The webapp I'm developing uses pageContext.forward() to send requests to different JSPs for processing (for example to send someone to a login page if they are not logged in), but once they are forwarded methods such as: request.getRequestURI() request.getServletPath() HttpUtils.getRequestURL(request) only return info relevant to the new page. How do I get the info for the original page? Thanks, August __ Do You Yahoo!? Send instant messages & get email alerts with Yahoo! Messenger. http://im.yahoo.com/

Hi, I'm trying to figure out the best way of deploying a web application at several sites, each with their own configuration (JDBC url etc).

So far all the examples seem to include any configuration inside the web.xml file.

Just put the JSSE JAR files in $TOMCAT_HOME/lib and configure the SSL HttpConnector in server.xml (there is an example there commented out). If you *do* need to rebuild it (for other reasons) the you'll find an explanation in the README file supplied with jakarta-tomcat-3.2.2.tar.gz. Basically, you need to download Ant, the "servletapi" package, Xerces, JAXP and JSSE and put them in a directory structure like: jakarta-tomcat jakarta-servletapi jakarta-ant jaxp-1.0.1 You also need to put xerces.jar and the JSSE JARs in your CLASSPATH before doing the build.

I am able to make mod_webapp.so just fine, but when I go to test apache with apachectl configtest I get the error: "Syntax error on line 72 of /usr/local/apache/conf/httpd.conf: Cannot load /usr/local/apache/libexec/mod_webapp.so into server: ld.so.1: /usr/local/apache/bin/httpd: fatal: libmm.so.11: open failed: No such file or directory" This is on a SPARC solaris 2.6 install. I downloaded the cvs on saturday night for jakarta-tomcat-connectors as well as the apr. Thanks, John Harris.

Tomcat Crushes after few hours of working
Folks, At the mod_Jk.log file at tomcat server, the following errors are displayed repeatedly: - [jk_ajp13_worker.c (584)]: Error connecting to the Tomcat process. [jk_connect.c (143)]: jk_open_socket, connect() failed errno = 111 [jk_ajp13_worker.c (173)]: In jk_endpoint_t::connect_to_tomcat, failed errno = 111 -- Do you have any idea what could be causing this errors? The WebPages that are at the tomcat crush after few hours of working. The only way we can solve this problem has been by rebooting the tomcat server and the apache server. Any help will be appreciated, Barnabas.
Is Tomcat not closing connections?
Hi, I have tomcat 3.1.1 installed on a solaris box. It is talking to apache on a different solaris box. Apache is setup to have a maximum of 256 processes but rarely actually goes above 150. When I check how many connections are talking to port 8007 I get over 400 using the following command : while [ 1 -eq 1 ]; do netstat -an | grep 8007 | wc -l; sleep 5; done How can this be happening? Is Tomcat not closing down connections that it has finished with? I am getting a LOT (~1 per second) of 'Connection caused software abort' execeptions which I have rebuilt tomcat to ignore (rather than the default action which used to be to shutdown!). Any help with this would be appreciated. George

ClassLoader
I've already seen that there are other people facing the same problem that I got. I'd like to use a classloader inside my servlet but it doesn't work because the classes in WEB-INF/lib are not available to the parent classloader. I also read that you I will have to put the DispatcherServlet into WEB-INF/classes. My problem now is that I don't know which classes I have to put there (which class is the DispatcherServlet in Tomcat 4.0 and 3.2??). Thanks in advance Jochen

I would have to disagree on this point. How successfully Tomcat does this in all situations is a different matter, but I think a lot of people want to do something like this: ... JkMount /*.jsp ajp13 ... ... JkMount /*.jsp ajp13 ... In this case, Tomcat has to know about the virtual hosts to have two unique root contexts. In fact, I've set up a system this way with the 3.2.3 version, but I couldn't get the same thing to work when separating the Apache and Tomcat machines from each other. IMHO, Tomcat should be looking at the contents of the ServerName field on requests from Apache to determine what host to use in its own configuration. Otherwise, you're stuck with running multiple instances of Tomcat like I am right now, or you're forced to run it on the same machine as Apache (and I have no idea why that works). Note: I did get this to work to an extent with machines separated, but it didn't reliably work under different forms of requests (HTTP 1.0 instead of 1.1 for IP-based hosts, IP instead of named-based hosts with the IP in the URL request instead of the name, and a few others that I forget).

RE: Growing Memory
I believe about the only thing that the JDBC-ODBC bridge, provided
with Java by Sun, doesn't do is leak memory. It does have threading issues
and it will cause a General Protection Fault/Application Error/Dr. Watson
error, depending upon your version of Windows. (In Sun's Bug Parade they
indicate that the bridge is experimental, unsupported, and not recommended
for any actual usage.)
In your case, its not your database drivers. One other thing that I
didn't mention before, remember that your servlet instance variables will
also be around (practically speaking) from first invoation/initalization
until the container stops. Having lists and maps here that can accumulate
data can also cause problems.

access violation error
Hallo, we are using tomcat 3.2.2 and JDK 1.3 on Win NT (we must use it) Our application consists of some JSPs and Action-Classes When two clients visit a JSP at the same time after starting tomcat (the page isn't compiled yet) Dr. Watson comes up telling us that there is an error (access violation) occured in java.exe. If one single user accesses all JSPs, so that they are compiled to the TOMCAT_HOME\work direktory, before any other user visits a page, everything works fine. Who can help? Guido Nottebrok

Thanks for the info.
I am using the JDBC driver in my servlets (jdbc:odbc:driver={SQL SERVER}).
This might be where my problem is.
What is the problem with this driver and is there a work around?

Do you know where I can see a correct configuration or do you have an

Get Server IP in a JSP
Hi all, I know this isn't really a question about Tomcat, but I figured that since Tomcat is all about Servlets and JSP's someone may be able to answer my question. Is there a way to query the server for it's IP address within and JSP or Servlet? This would be on a Windows machine. If there is can that IP address be written into a URL Rewrite? I'm writing an Equipment management system for work and it is all written in JSP. My problem is that the machine I'm using as my Tomcat server is my Workstation. I'd like to move it to a dedicated machine, but our Workstations do not have DNS, so typing in the machine mane does not work. I have to hard code in my IP address in order for the system to function. The problem with that is that we have Dynamic IP addresses. Mine hasn't changed in a long time, but it could and if it does the whole system won't work. Could anyone offer a suggestion to my IP address problem?

Re: Re: Tomcat crashes simultaneous more connection above 990+
Hi folks, coincidentally I am also having problems with large number of concurrent connections to Tomcat getting errors when we try and connect many clients concurrently to Tomcat. Does anyone have experience of this sort of Tomcat usage or should we be looking at a different servlet container for heavy loads. The setup is as follows Tomcat 3.2.2. on WinNT SP 6 running as a standalone servlet container. Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C) Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode) We have a test environment where a number (2-4) of other machines, with multi-threaded clients (30-1000 threads) bombard the servlet in an effort to test the servlet performance. This leads to a number of problems 1) First of all the mutli-threaded test clients (also written in Java) occasionally throw a NoClassDefFoundError when the following line of code is executed PrintWriter out = new PrintWriter(conn.getOutputStream()); The class that is not found is a Socket class (sorry I don't have the trace at the moment) is not found. This happens when the number of threads on the client is high (c. 1000). Obviously it is not a Tomcat problem so I shouldn't even mention it. It is easily worked around by catching for the error and retrying. It looks slightly similar to a problem in JKD 1.2 where the Calender class would load a ResourceBundle containing Locale info (in particular Date format info) and would report a MissingResourceBundle exception occasionally with a high number of threads creating Calenders simultaneously. A chain of resources are created and loaded into a HashTable during a call to load the resource, but some of the resources may be garbage collected during recursive calls to ResourceBundle.getObject() resulting in a MissingResourceException. Since garbage collection is not very frequent the chances of this occurring during a resource access are quite low. I only mention it since it has some surface similarities with my problem. For more info look here http://developer.java.sun.com/developer/bugParade/bugs/4335714.html 2) The second problem may be an actual Tomcat problem. It is caused by the same line of code and is an IOException saying that the connection has been refused. Even when we increase various parameters in the server.xml file - to ensure that Tomcat will accept more connections it does not seem to work. This problem has been demonstrated to be independent of out servlet and appears when accessing a resource such as a JSP file. Again this is not a critical problem since we can catch the exception and retry the connection but it is puzzling as to why the high backlog figure doesn't ensure that the socket connection attempts are not queued. Again sorry that I don't have a trace to hand at the moment. 3) We have more serious problems on the Tomcat side, after some while (a couple of hours) with a high number (1000 -1500) of clients continuously connecting we get errors in the tomcat logs "2001-08-07 09:33:47 - Ctx( /certresolver ): IOException in: R( /certresolver+ /certs + null) socket write error (code=10055)" A quick search for code=10055 reveals it to be an error code thrown by winsock, however it covers a couple of different situations including trying to increase the timeout on a socket. The one that appears most appropriate to this problem is a bug report at sun http://developer.java.sun.com/developer/bugParade/bugs/4474929.html "Embedded in the exception's message string is code 10055. Under Win32, this error is WSAENOBUFS which means the TCP/IP stack has temporarily run out of buffer space and cannot complete the write. Microsoft has verified this as a bug in the WinSock TCP/IP stack (see the MSDN article ID: Q201213). This would be a recoverable error if not for the way the Java native code handles the error. The recovery would simply be to wait for the stack buffers to empty and try sending the same data again at a later time." It could possibly be related to this error but without more information in the exception we can't tell. Has anyone ever experienced something like this? 4) The final problem is that Tomcat reports is an OutOfMemoryException after continuous usage with a high number of clients. Increasing the memory available to the Tomcat process (using -Xmx500m) does not make the problem go away, the taskmanager reports that the Tomcat process is only using a fraction of its allocated memory. Could this be a related to the previous discussion on upper limits for blocking I/O connections per process Many thanks if you can help in any way.

Re: Tips b4 installing Tomcat on IIS5/Win2k ?
One tip, Just make sure that your IIS is fully patched!!! We do not need anymore Code REd servers out there, since I get enough incomming traffic already. Also make sure that your WINNT directory and all of your JSP's and HTML files are not on the same Hard Drive partition. If they are you are more likely to be hacked.

Virtual host is resolved at the time when connection is being made between the Web browser and Web server. Only at this moment the Web server knows the IP address, Host name, and the port to which the connection was made. If you want particular virtual host to access particular context in Tomcat, you need to put all the instructions (found in mod_jk.conf) within the block of your virtual host in the httpd.conf file, and do not put those instructions outside the block. I mean all the instructions, beside maybe LoadModule jk_module libexec/mod_jk.so which should be put BEFORE LoadModule rewrite_module The directives: JkWorkersFile , JkLogFile , JkLogLevel , Alias , , JkMount , JkMount should be put inside the VirtualHost block, and, unfortunately, the simple Include mod_jk.conf at the end of httpd.conf will not work. You have to edit the httpd.conf manually. The stuff which you put outside blocks is available to all virtual hosts defined in httpd.conf > > The only way we could get rid of that behaviour was , to enclose the > contexts in server.xml > with the appropriate virtual host tags. This may have worked (I did not try) for some reasons since some information about the host is passed from Apache to Tomcat with the request in header lines, but it would only work for contexts which are not automatically deployed in TOMCAT_HOME/webapps directory and only for certain types of virtual hosts (read documentation on virtual hosts on www.apache.org to see that there are many ways in which virtual hosts can be specified). Moreover, you can start serveral tomcats and attach them to different server.xml/workers.properties with different connector port, and each of your VirtualHosts can talk to its own tomcat. > > > > > Jan > Labanowski An: [EMAIL PROTECTED] > <[EMAIL PROTECTED]>Kopie: Jan Labanowski <[EMAIL PROTECTED]> > Thema: Re: Newbie: Apache Tomcat mod_jk Virtual Hosts > 13.08.01 > 03:59 > Bitte > antworten an > tomcat-user > > > > > > > On Sun, 12 Aug 2001 [EMAIL PROTECTED] wrote: > > > So would you say that this entry in the server.xml is unnecessary: > > > > server.xml: > > > > > > > > > > docBase="/home/vs04025/jspwebapps" /> > > > crossContext="false" > > > debug="0" > > > reloadable="true" > > > > > > > > > > > > > Again...

RE: Growing Memory
You could try one of the profiling tools out there (we use a very old version of OptimizeIt) to spot where the memory is going and how it got there. A few things that could be your problem, though: 1. You are putting very large objects into sessions and your sessions have long or no expiration times 2. You have an object with a static variable that you keep adding to (map, list, set, etc) and aren't ever clearing 3. You have some form of buffered IO where the buffer isn't being flushed.
