Hijacking the coyote connector
In tomcat 5.0.28, we were able to replace the coyote connector using a "className" setting in the connector in server.xml. In tomcat 5.5.9 it looks like "className" is ignored. Looking at the source, it looks like the Connector is hardcoded in. Is this the case or am I missing something? My next attempt, I repackaged our connector to replace the org.apache.catalina.connector package and put that in the -Xbootclasspath to override the released version. With -verbose:class set I can see my Connector being loaded, but the next class loaded is java/lang/reflect/InvocationTargetException and the JVM terminates. The documentation says that this is used to wrap an exception when a method or constructor is called by reflection. As I said above it looks to me like the constructor is called directly not via reflection. Am I missing something obvious? I know that using the AJP connector is a cleaner way, but we estimate the serialization overhead will cost us about 5% on our platform.

Re: useBeans problem
Ok i found two other installations of JDK on the machine.

I think I've finally got everything working the way it's supposed to except mod_jk for my user directories. I tried to do the userdir thing you suggested, but I couldn't get it to work. Right now I use symlinks to my individual users' website directories, but now that I've discovered Alias I'll probably switch completely to using Aliases. I created a test Alias point to the ~/webspace/webapps directory in my personal account, but I can't seem to JkMount it, and I can't figure out why. Here is the mod_jk portion of my httpd.conf file: #mod_jk stuff LoadModule jk_module modules/mod_jk.so JkMount /*.jsp wrkr JkMount /servlet/* wrkr # Deny direct access to WEB-INF AllowOverride None deny from all Alias /michael /home/michael/webspace/webapps Options FollowSymLinks AllowOverride None I don't know if I need that stuff - It was part of a block that seemed to be unecessary, so I took it out. I tried putting my JkMount statements inside the block, but when I tried to restart Apache it gave me the following error: JkMount can not have a path when defined in a location In /home/michael/webspace/webapps there is a file called colors.jsp.

Re: Cannot forward after response has been committed
I put a 'return' statement after every 'forward' statement in all my jsp pages and now it seems to be working. Thanks for your feedback. Actually, my linebreak occurs in the <% %> tags.

I have an index.jsp page that checks a user's access level:

String userid = (String)session.getAttribute("UserId");
if (userid == null) {
pageContext.forward("login.jsp");

And yet the above page works even with the <%@ page language="java" %>

What do you propose -- that I remove the <%@ page... %> line?

Yep, looks ugly.
What is even worse is code that sends a redirect and does NOT do a return.

Why doesn't my context work?
I wrote in yesterday asking about how to map certain directories to tomcat contexts. When nobody answered me I did some Google research. I didn't find much that made sense to me. I prefer man and info pages to what I found. Anyway, I created a file called home.xml in /opt/tomcat5/conf/Catalina/localhost. I made home.xml by copying admin.xml and altering it. Here are the contents of home.xml: If I understand this correctly, when I ask for www.espersunited.com/user/index.jsp, Tomcat should deliver to my browser the contents of /home/michael/webspace/webapps/index.jsp. I restarted Tomcat and went to www.espersunited.com/user/index.jsp in my browser. I got a Tomcat 404 Resource Not Available error. Why? Do I not have the syntax of my context tag right? I would think that this would be a pretty basic thing to do, but maybe not since no one has answered me. What should I do?

How to define paths to inidividual user directories
I've recently installed Tomcat and linked it to Apache with the mod_jk connector. It seems to be working - I can type a filename.jsp script and save it in a file in /opt/tomcat5/webapps/ROOT and then navigate to www.espersunited.com/filename.jsp and it works. I have a number of users at espersunited.com. Each of these users has under their user accounts a directory called ~/webspace/html. Here they put their static (and .PHP) web site files. I would like to create a ~/webspace/tomcat directory under each of their accounts for .jsp and/or servlet files, but I'm not sure exactly how to map this with Tomcat. I find Tomcat mapping very confusing. Can anyone help me with this? -Michael Sullivan- - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I think we should handle the rest off list not to bother the list anymore. Just to give you another option if you like. I don't even use mod_jd. I make use of Apache's reverse proxy feature. In my httpd.conf, I add the following lines in my virtual host: ProxyPass /app http://localhost:8081/ ProxyPassReverse /app http://localhost:8081/ Just make sure you have loaded the following modules: LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_ftp_module modules/mod_proxy_ftp.so LoadModule proxy_http_module modules/mod_proxy_http.so LoadModule proxy_connect_module modules/mod_proxy_connect.so What the above does is when Apache sees an url like: http://www.myhost.com/app It passes all traffic to tomcat which is listening to port 8081 (on the same machine). The beauty of this is that you can put this in your ssl.conf too and Apache will handle all encrypted traffic and passes it on to tomcat. The only advantage I see from mod_jk is if you are using it for load balancing too. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Where do I get a "tomcat webapp that serves jsp's"? This is what I need. I thought one was built into Tomcat -- in fact I thought JSP serving was the original purpose of Tomcat. If Tomcat doesn't have any such webapp, where do I get one? I certainly can't write one, as I'm not a Java programmer. I am limited in my knowledge of tomcat but from my understanding, tomcat can be ran either as a standalone server or behind a webserver. In your case, it seems like you don't actually need a webserver in front so you should be able to connect to tomcat using the url: http://localhost:8080/ Just make sure in your server.xml that you have this line: or whatever port you want to connect to. In fact, I don't think you even need mod_jk if you are using tomcat as a standalone. Hope that helps. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Cannot connect to database using DataSource
I have a MySQL database in which I created a database named, javatest,
and I am using Tomcat 5.5.9. I have unable to connect my database using
Java's DataSource method. Here is my ROOT.xml setup for my application
context:
username
javauser
password
javadude
driverClassName
com.mysql.jdbc.Driver
url
jdbc:mysql://localhost/javatest?autoReconnect=true
I created a simple servlet to test the database connection:
public class TestSQL extends HttpServlet {
private Connection conn = null;
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws IOException,
ServletException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
try {
Context ctx = new InitialContext();
Context appContext = (Context)ctx.lookup("java:comp/env");
DataSource ds = (DataSource)appContext.lookup("jdbc/DBTest");
conn = ds.getConnection();
} catch (Exception e) {
e.printStackTrace();
}
if (conn != null) {
out.println("Connection successful");
} else {
out.println("Unsuccessful");
}
}
It prints out "Unsuccessful". I also tried using the traditional
DriverManager and that works. Here is my web.xml in case it is needed
for analysis:
http://java.sun.com/xml/ns/j2ee"; >
jdbc/DBTest
javax.sql.DataSource

TestSQL

I would appreciate it very much if someone can have a look at this and
tell me what I am doing wrong with the DataSource alternative.

This is probably an obvious question to most but I am new with tomcat 5.5 so I am still trying to figure things out.

This is what I have in my server.xml: It works when I point my browser to http://www.myhost.com:8081/ and it shows a customized welcome page from my index.jsp.

RE: Memory leak in Tomcat
Ingrid, I am not on the tomcat developer committer list so my reply is just an FYI from my own experience. I saw unstable performance myself in a very similar deployment of Struts applications similar to yours. I too thought there was a memory leak and there may be, but I don't think it is in the applications themselves. The behavior I saw, led me to think it was related to socket allocation as after a period of time my system began to complain and slow down and other socket related programs began to complain about timeouts, etc. I found that my tomcat needed to use virtual memory to avoid out of memory exceptions. I added physical memory and the problems all but went away, however it still occurs just less frequently.

If you're planning for a high-performance high-load system, don't use Windows 2003 Standard Edition. It has serious limitations in the TCP/IP stack. I wasn't able to open more than ~3500 concurrent network connections to a database cluster. The common error was "no buffer space available". Linux on the same machine works fine. Would be interesting if Win 2003 EE or DCE has the same limitation. The real pain was not the limitation itself, but that is _not_ documented.

IIS connector problem
I'm using Tomcat 5.5.9 and IIS 6 on a Windows 2003 machine. Isapi_redirect.dll (version 1.2.14) seems to work if use a full url such as this: http://localhost/jsp-examples/index.html All the various jsp examples work. However, if I don't fully specify a document, such as http://localhost/jsp-examples, I get a 404 error. If I use http://localhost:8080/jsp-examples things work. I have [uri:/jsp-examples/*] in my workers2.properties, and I thought that should ensure that pages would be passed to Tomcat for handling. Unless Tomcat isn't finding (or using) my configuration file...? Other (probably related) symptoms: I'm not getting any information into the "isapi_redirect.log" file. The folder where it should be exists, and its pointer is in the registry, but nothing is getting there... No shm.file is being created in the work folder. Also, I'm not seeing any "isapi_redirect.dll" entries in the IIS logfiles (which should be there if IIS is passing data onwards?). If this wasn't a clean installation, I'd think something else was handling jsp requests. I've been trying to see if there's a detail I've missed, but sifting through the different howto's (for older versions) has been challenging. Thanks in advance, Mike P.S.

Re: session problems: www.blahblah.com versus blahblah.com
I guess I was hoping there was some server-level redirect. I'm not sure how I would put the meta redirect in all my pages. My app is a complicated mess (my fault - my lack of skill). The issue is that my users are clicking a PayPal "Subscribe" button, which sends them off to PayPal. Part of the hidden information sent to PayPal when the user clicks that button is the return path. So if user comes to blahblah.com, clicks the Subscribe button it sends them to PayPal with a return path of www.blahblah.com (because that's what I'm telling PayPal to do.) I'm thinking now I can just look at the URL they're at now and set my PayPal return path dynamically... If they're here as blahblah.com, I make sure to tell the PayPal form that the return path is blahblah.com. If www, then return to www... Thanks for your suggestion though. I can even continue using PayPal's encrypted buttons - I'll just make two buttons, one for www, and theother for just blahblah, and display the appropriate button based on current situation. Still, I think I was hoping that somewhere in server.xml I could say "all requests for blahblah.com should be mapped to www.blahblah.com." Thanks all.

Howdy. I'm having some problems with sessions. If my users come to "blahblah.com", then go away, then return, they get a new session id (for www.blahblah.com). But if they come to www.blahblah.com, leave, and return (via link from external site), they keep the same session.

jboss-tomcat bind issue
Please let me know if you think this e-mail belongs on a JBoss list instead of this one... Problem === JBoss 4.0 bundled with Tomcat 5.5, out of the box, will not bind to port 8080 for all interfaces. i.e. I can telnet to the port from the localhost, but not from outside. Please let me know how to bind to this port properly. On local machine... telnet 127.0.0.1 8080 Trying 127.0.0.1... Connected to 127.0.0.1. On remote machine... (IP address masked slightly) telnet 208.100.x.x Trying 208.100.x.x... - this will eventually time out Running a netstat -anp | grep 8080 shows this: Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp0 0 :::8080 :::* LISTEN 17487/java From the above, I can see that java (jboss) has a server socket listening on port 8080, but the local address looks off.

Re: Max thread/session timeouts
Peddireddy,
how about your project? I have finally found a solution here ;-) If the
database handles requests faster, the load on my Tomcat(s) are lower,
because of the lower count of active threads. This does not resolve the
problem induced by the apparent connection limit on Windows 2003
Standard Edition, especially in peak situations with ~3000 active
Threads. I've got the computing centre to install Red Hat Enterprise 4
on one of the servers and voila, the errors are gone!
Admittedly, it seems that Linux is a bit slower when getting into a high
thread count, it's sufficiently fast for my project. Also, it seems
faster on low thread counts (<500). A simple servlet building a XML tree
(without any database access or other 3rd party access) runs about 30%
faster on Linux than on Windows on the same machine.
I think the slower response of Linux with high thread counts is induced
by a slower thread handling. An engineer from Red Hat will try to
optimize that tomorrow..

Strange mrf files generated in tomat temp directory
I am using Tomcat 4.1.29 on solaris 9. I have files uploaded to my site and then I write them to the temp dir using File.createTempFile() in anticipation of moving them elsewhere. I have noticed that somthing else is writing very larg files to this directory as well. Some of the files are > 3GB. They seem to be using the same File.createTempFile() facility because they all have a prefix followed by a 3 to 5 digit number and then .tmp ( mrf2393.tmp or mrf40389.tmp) Where do these files come from? Thanks Michael

same problem over here. The computing centre of our client can't provide
Linux servers. I'm struggling with this problem for 3 weeks now.

My experience was that with a single Tomcat on a large machine, you'll
never use that box fully. Besides that you can't get the Sun JVM to
accept a large amount of threads while giving them enough memory, Tomcat
seems to have performance problems with 3000+ threads busy at the same
time. The BEA JVM (JRockit) performs better in terms of memory and
threads but is slower than the Sun JVM. If you have rather complex
database operations performed by your webapp, this will get you into
trouble, because if there is a single bottleneck in the whole system,
the requests will pile up in the server, it hits its thread limit, and
ceases operation.
So, I have made good experiences with 4 Tomcats on a 2xXeon with 4GB.
The server's load is somewhere between 70% and 100% while running with
high load and can handle more concurrent requests than a single Tomcat.

We use 2003 Standard Edition and get the following limitations:
. Windows only provides 2GB memory to all applications running,
regardless of how much memory you have. All other memory is used for
Windows itself. With a registry key, you can extend this to 3GB. I
don't have the key handy, but it can be found in MSDN.
. The somewhat larger problem is the crappy TCP stack on Windows. A
single Tomcat easily handles 1000 concurrent connections, but if I start
4 Tomcats, I get a WSAENOBUFS error ("An operation on a socket could not
be performed because the system lacked sufficient buffer space or
because a queue was full") at about 3300 concurrent connections.
Because each Tomcat runs with his own instance of the JVM, I suppose
the problem is Windows, the network or anything else that is used by all
Tomcats at the same time. Even worse, after such a crash, there is a
10% chance, the Tomcats not resuming normal operation but crashes
completely.
. Windows has a default limit of 5000 ephemeral ports that can be used
fo outgoing connections. This can be changed with the MaxUserPorts
registry key. Also, the TcpTimedWaitDelay key is relevant for network
performance. Both are described here:
http://msdn.microsoft.com/library/en-us/randz/protocol/tcp_time-wait_delay.asp
I'm now really irritated by this problem. I need a capacity of about
15000 concurrent connections for my project. I also have 3 2xXeon
servers here, but windows (or anything else) doesn't allow more than
~8000 connections until it dies.

How much extra memory > do I need if I say change it to, say, 500? Thanks. just a few facts on threads in Tomcat: . you'll need (Xss*max_threads)+Xmx+x memory in your box, where x is the memory needed by the basic JVM tasks besides the thread space (say, 100MB). . on ia32/Windows, you can only assign 1.6GB (Xmx-)memory to a single JVM. A value above it will break the 2GB barrier and will not run. . you need to find the balance between max_threads and Xmx. A lower Xmx gives you a higher max_threads and vice versa. . Tomcat on Windows doesn't scale well. Use multiple Tomcat instances on one box if you have a large box. In my setup, I run 4 Tomcats on a 2xXeon system with 4GB memory. Each Tomcat gets 1000 threads and 512MB. This is _much_ faster than a single Tomcat with all memory and 4000 threads. . Windows 2003 Server, at least the Standard Edition has major limitations in both TCP connections and memory. There are some workarounds using esoteric registry keys, but none of them works well. Windows is a crippled desktop os that wants to be on the server. If you want really high performance on large boxes, use Linux (Kernel 2.6!). You even get a better administration interface.

Re: java.library.path when running as a service
My PATH variable already includes $CATALINA_HOME\common\lib, and it definitely has worked in the past. Wouldn't this also affect Tomcat launched from the command line? My problem only occurs when Tomcat is a service. Also, can you elaborate on what the delay loader hook is? Thank you.

java.library.path when running as a service
I have been running a servlet with Tomcat 5.5.7 for a few months, I left it alone for a while, and now I get an UnsatisfiedLinkError when the servlet tries to load a native DLL. The error says the DLL cannot be found in java.library.path. The DLL I want to load is located in $CATALINA_HOME\common\lib. When I just run Tomcat from the command line, everything works great, no complaints. When run as a service, I get this problem. I tried setting java.library.path via the JvmOptions in service.bat, but in that case I get an UnsatisfiedLinkError which refers to dependent libraries for the DLL.

I agree, something like this works pretty well, but you still need to

Re: No more than 500 threads on Windows 2003?
mmh.. "You may hear the terms "green threads" and "native threads". This refers to the Unix implementations of Java. When Java 1.0 first came out on Solaris, it did not use the native Solaris library libthread.so to support threads. Instead it used runtime thread support that had been written in Java for an earlier project code-named "Green." That thread library came to be known as "green threads." "Thread support on Windows used the native libraries from the start, but on Solaris green threads were used. That meant that threaded programs running on Solaris didn't get the benefit of the native libraries. In particular, if your Java program was executing on a multi processor Solaris system, it was never the case that different threads could execute truly in parallel by being dispatched on different processors. There are other benefits too, to do with more efficient mapping of I/O system calls." -> Just Java 2, Fourth Edition, by Peter van der Linden So Windows always uses native threads. Seems to me like a Windows system or license limit. I have already asked tech support of the hosting provider who installed the server, but no answer yet. -- Michael On Fri, Jul 01, 2005 at 11:02:44AM +0200, delbd wrote: > I may be wrong, but as far as my knowledge goes on green threads, this is > just a matter of > dedactivating native system thread to use an internal threading / sheduling > system in the jvm. > I see no reason why this wouldn't exist on windows version of jvm. > > Le Vendredi 1 Juillet 2005 10:39, Michael Kleinhenz a écrit : > > > > as far as I know, the concept of green and native threads only applies > > to Unix systems...? > > > > -- Michael > > > > > > On Fri, Jul 01, 2005 at 10:44:38AM +0200, delbd wrote: > > > Maybe you could switch the jvm to green threads ? > > > Le Vendredi 1 Juillet 2005 09:57, Michael Kleinhenz a écrit : > > > > > > > > maybe.

No more than 500 threads on Windows 2003?
Hi, I'm currently integrating a SOAP-based middleware on Tomcat (5.5.9) with Sun JDK 1.5.0_02 and get into problems when using maxThreads with a value greater than 500. Tomcat locks up completely without getting back to normal operations after a while. No exception or error is reported in the logs, it just stops. All connections are refused after the lockup. Tomcat has enough memory (>1GB) assigned with the JVM options. If I use maxThreads="500", the server runs fine, but 500 is not enough for my project ;-( I tried to increase the stack size, but this doesn't help.. The connector is defined as: If I change 500 to 700 or more, Tomcat locks up. Is this a Windows problem?? Hardware is not an issue, I think.. (dual Xeon 3,4GHz, 4GB)..

You can't replace j_security_check as it's part of the servlet spec. You
could e.g. try to set the security principal yourself and use
org.apache.catalina.HttpRequest to cast your HttpServletRequest and
build something custom around the declarative security.

and in-server forward from included resource
Hello! I sent this message to dev list a week ago and did not get an answer, so I thought that I might come across someone in the user list, who might help me. I also had raised this question about three months ago, and was assured by a member of dev group, that my concerns would be shared with JSP spec group, so I would like to check on the progress. In short, I want to make a change in JSP spec, and I don't know where should I address my concern. Tomcat is a reference implementation of JSP spec, so I thought this might be a right place. I cannot comment on JSR53 either. Here is my situation: I have a resource, included in JSP page. The included resource (in my case a struts action, but this does not matter) performs in-server forward (or redirect and then forward) to a location with actual content (in my case it is JSP page). The problem I am having is that response stream is closed after my included resource is processed, and the rest part of parent page is not processed. I was pointed to the spec: JSP version 2.4, section 8.4 reads: "Before the forward method of the RequestDispatcher interface returns, the response content must be sent and committed, and closed by the servlet container." I would like it to be updated to something like this: "Before the forward method of the RequestDispatcher interface returns, the response content must be sent and committed, and closed by the servlet container, IF REQUEST WAS NOT INCLUDED INTO ANOTHER REQUEST." Here is the reason: I want to be able to create components in JSP using jsp:include. I want to be able to include serlvets or Struts actions or other request-processing modules, which then would forward to actual content - a result page, which would become a piece in the main page. And I want to separate the modules. But I cannot apply clean MVC model using current JSP spec, because included resource must generate output itself, and must not perform a forward. Tomcat is a reference implementation of JSP spec, and it does not behave like I want. On the other hand, Resin and Jetty work pretty much how I expected. It would be great if Tomcat could do this too. Maybe with some kind of switch or setting. If anyone from this group has a chance to influence JSP spec, or can point me the direction where I can address my concerns, I would be grateful for help.

I already tried it, and it did not work. Session ID is separated by

differently and is not shown as URL parameter.

Re: isRequestedSessionIdFromURL() returns false
If both methods return true, they would identify the first request after session has been established with browser which supports cookies. I try to keep GET requests clean to encourage browser to keep its page history from growing. When I detect this request, I perform a redirect to the same location to clean URL up. After redirection URL will be clean, because session ID will be contained in cookie only. I need to do this only once. With isRequestedSessionIdFromURL() returning false I cannot do what I need :-( Any ideas?

isRequestedSessionIdFromURL() returns false
Hi, I hope am I in the right mail-list with this question. I guess that if I use Tomcat, then HttpRequest.isRequestedSessionIdFromURL() is implemented by Tomcat. I have a request, which contains *both* session ID in cookie *and* session ID in the rewritten URL. isRequestedSessionIdFromCookie() return true, but isRequestedSessionIdFromURL() returns false. It seems that isRequestedSessionIdFromURL() should return true. Is this a bug? I am using Tomcat 4.1.31.

Hi Everyone!
There is a servlet i found from a book that utilizes the parameters from
servlets but whenever i run it the browser doesnt seem to open the class
properly and instead it only downloads the .class file. I think the problem
here has something to do with the new Tomcat version. Can someone try
deploying the application so that I'll be able to find out whether what the
problem really is. Below are the codes i used:
the code below is for Form.html where i have to enter the information that
will be passed onto the servlet:
Parameter Servlet Form
Name:
SSN:
Age:
email:
and here is the code for ParamterServlet.java:
package chapter2;

public class ParameterServlet extends HttpServlet {
public void init(ServletConfig config) throws ServletException {
// Always pas the ServletConfig object to the super class
super.init(config);
}
// Process the HTTP Get request
public void doGet (HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request, response);
}
// Process the HTTP Post request
public void doPost (HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
response.setContentType("html/text");
PrintWriter out = response.getWriter();
out.println("");
out.println("");
out.println("Parameter Servlet");
out.println("");
out.println("");
// Get an enumeration of the parameter names
Enumeration parameters = request.getParameterNames();
String param = null;
// Iterate over the parameter names,

while(parameters.hasMoreElements()) {
param = (String)parameters.nextElement();

RE: Servlet Concurrency Issues
Thanks Chuck, that was exactly the problem. I was under the very poor assumption that a new thread and newly instantiated servlet object was created every time a request was made, instead of all threads working on only one instance of an object. To mimic the desired behavior I've fixed the problem by adding this (implements SingleThreadModel)... public class ServletName implements SingleThreadModel Now it would seem that if several 100 people were to access a servlet that every time the following code was hit by a new thread: PrintWriter out = response.getWriter(); It would direct all output (using out.println()) from all threads to the most recent person to access the servlet. Follow up question: With this in mind, what is the most common method of writing thread safe code?

Probably not a configuration problem but rather implementation errors in your servlet or some related object (such as the DB connection).

Servlet Concurrency Issues
I've recently developed a servlet that connects to an AS/400, and returns results off an sql query based off criteria submitted by a form. I've had pretty much exclusive use of the Tomcat server during development, but when I started allowing other users on it, I stumbled on some problems. Basically what happens, when user A submits the form, and then 2 seconds later user B submits the same form. User A stops getting results, and User B receives the output for his request as well as the end of User A's request. User A is on a different computer than B and both have different session ID's. I'm sure this is a configuration error on my part, but would appreciate a direction on where to look. PS - I create a session if it doesn't exist, and store the username and DB connection in it. (Will use JNDI later) I'm using Tomcat 5.5.7

How can I enable Well in fact the traffic uses ajp13, a protocol which is not really "clear text". It's a binary format for optimization reasons.

Yes, this is an example from the book "Mastering Jakarta Struts". The tomcat
version used in the book is really a lot older, so i had to read the
documentation of version 5.5 and did everything written there. I structured
the directory hierarchy correctly and even exercised the proper source code
management.
Here is my web.xml code:

This is my first ever servlet and i hope it will
finally work. Please Lord, make it work...

SimpleServlet
This servlet plays the "controller" role in the MVC architecture
used in this application. It is generally mapped to the ".do"
filename extension with a servlet-mapping element, and all form
submits in the app will be submitted to a request URI like
"saveCustomer.do", which will therefore be mapped to this servlet.
The initialization parameter namess for this servlet are the
"servlet path" that will be received by this servlet (after the
filename extension is removed). The corresponding value is the
name of the action class that will be used to process this request.

To my desperation I even added a context path to the server.xml which was
practiced for older versions of tomcat. I also checked whether the web
application was deployed and the tomcat manager indicated that, yes, it was
already deployed. But i can't seem to make the servlet work. I kept
accessing it at http:/localhost:8080/wileyapp/servlet/chapter2.SimpleServlet
but it just doesnt work. I even tried the other tutorials available online
but these also didnt work. what seems to be the problem here? Im actually
considering using an older version of tomcat because there are more
tutorials and pointers for using them.

I am having difficulty getting Tomcat to run on OS 10.3.9 with latest
1.4.2 java.
I am able to get $CATALINA_HOME/bin/catalina.sh version to work, but
startup doesn't seem to want to work.
Any suggestions from other MAc users would be appreciated.

Re: Can a servlet receive its own request?
Yes, I'm now going the HttpClient route - and yes, I also realized that the object to be launched doesn't have to be a servlet at all. I was just anchored in thinking along those lines since I thought that the servlet would be the one receiving its own response. Anyway, I think I'm on the right track now.

If however, as I suspect might be the case, your servlet is going to actually be awaiting a reply from the outside server, then you should look at using Commons HTTPClient. I'm relatively sure it supports SSL connections, and then all your doing is making a remote request, awaiting the response and processing accordingly.

CORRECTION: Can a servlet receive a response to its own request?
Simple question, but it's driving me nuts. I really don't want to get into the whole web service business - all I need is for a servlet to be the recipient of its own request. Or - in other words - can a servlet act like a web browser - just without the GUI? Use case: - Servlet issues https request to an outside server (via getServletContext().getRequestDispatcher(https://www.someoutsideserver/) ) - Outside server processes request and responds with POST response (also via https). - Servlet [somehow] is able to be the recipient of the response. - Servlet parses the response and stores data to the database. Notes: - The servlet is not the default servlet on that tomcat instance. - Everything happens via https and I expect the outside server will listen on 443 and tomcat on 8443 ANY suggestions would be very helpful - this seems to be a tricky one.

Scheduled task in tomcat - how?
I need to create an automated task in tomcat that gets launched every two hours or so, does its work and then sleeps again. The task needs to send some request values via a secure (https) POST to a cgi script running on an outside server, then receive the response, parse it and put it into the database. The response doesn't return the values as request parameters, but instead simply returns records in CSV (comma separated values) format, one record per line. So, here's what I'm pondering: a.. What's the best way to create that automated (scheduled) task and run it as a servlet under tomcat (5.5.9)? b.. You guys might laugh, but the last time I parsed CSV as part of the HTTP response was in my Perl days (looong ago) - is there some servlet support for doing this, or do I need to code alll this stuff myself from scratch? c.. Finally, what's the best approach to 'receiving' the response? The servlet issueing the request is obviously the requester, but since this is running inside of tomcat, how do I route the response to that servlet? Maybe I'm overthinking this, but I'm not sure how a servlet can be the recipient of its own request. Hope this makes sense. Any input on one or more of these questions would be appreciated.

Re: Scheduled task in tomcat - how? 2
I was just thinking this: IF there would be another tomcat instance running, on a different port, then this one could issue the request and when called back the default servlet would pick up the response. Of course that's not what I'd like to do - wasting resources on a separate tomcat instance would be my very last resort...

RE: question about load-on-startup in web.xml
If I were doing it I would put a singleton class in the /common/lib/ that had a Hashtable and in my application's startup I would get the singleton and have the first application I want to load put a string "loading" (or whatever) in the Hashtable of the singleton with the key "webappY". The second webappX get the singleton and look for "webappY"/"loading". If it is still there sleep and check again later. When webappY is finished starting it removes the 'loading' from the Hashtable of the singleton and when "webappX" sees it is gone, it continues. Michael Oliver CTO Alarius Systems LLC 6800 E.

The work directory still exists in v5.5; it wasn't necessary to delete it in this case (having figured out from the first reply that the misnamed package was the problem). Caching *did* occur to me as a potential problem, however. It's notable that for some pages, the error doesn't always appear, or often different errors appear on successive refreshes. I suspect that *that* is a caching issue (and also that it is common enough to have been explained several times elsewhere, so this isn't a question, just an observation). - MS ___ Yahoo!

If there is any excuse it is that I'd had what *looked* like the same problem with two earlier attempts; the package name was not the problem there. Because I thought this was the same problem, I probably didn't consider the obvious answer again.

Simple JavaBeans applications not working (newbie question)
Hi,
First off, let me apologise for the level of detail in
this message; if possible, I'd have made it shorter.
Anyway, I'm trying to learn J2EE; Tomcat seemed like a
good choice to learn the underlying technology, rather
than a particular JSP/Servlet container's deployment
tool. I can get 'plain' JSP pages working fine.
Unfortunately, I'm having major problems developing my
own Javabeans applications for Tomcat; they all fail
as shown below. The demos that come with Tomcat work
fine (although I can't get the demo at
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/appdev/sample
to work; However- that's another story)
I understand that I should simply be able to drop the
directory structure containing my program into
$CATALINA_HOME/webapps, restart Tomcat (I'm using
5.5.7) and have it work.
Its contents (root:root ownership, Tomcat running as
root) is:-
skeleton
skeleton/subapp
skeleton/subapp/skeleton.jsp
skeleton/WEB-INF
skeleton/WEB-INF/classes
skeleton/WEB-INF/lib
skeleton/WEB-INF/lib/subapp
skeleton/WEB-INF/lib/subapp/Beany.class
skeleton/WEB-INF/lib/subapp/Beany.java
skeleton/WEB-INF/lib/subapp.jar
skeleton/WEB-INF/web.xml
Contents of files listed at end of message.
Here's what happens when I try to run it:-
(1) When I try to access
http://localhost:8080/skeleton/subapp/skeleton.jsp
with the setup as above, I get
HTTP Status 404 - Servlet
org.apache.jsp.subapp.skeleton_jsp
is not available
message Servlet
org.apache.jsp.subapp.skeleton_jsp
is not available
(2) If I move skeleton/WEB-INF/lib/subapp to
skeleton/WEB-INF/classes/subapp,
I get
HTTP STATUS 500 - EXCEPTION REPORT
The server encountered an internal error ()
that prevented it from fulfilling this
request.

org.apache.catalina.loader.WebappClassLoader.loadClass
(WebappClassLoader.java:1332)
[... SNIP ...]
java.lang.Thread.run(Thread.java:595)
(3) If I remove the deployment descriptor altogether,
I get:-
HTTP STATUS 500 - EXCEPTION REPORT
The server encountered an internal error ()
that prevented it from fulfilling this
request.
EXCEPTION
org.apache.jasper.JasperException:

org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:39)
[... SNIP
...]
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
In short, it fails; in three noticeably different
ways, granted; but it still
fails. What on EARTH am I doing wrong or missing out?!
I'd really appreciate
some feedback on this. Thank you in advance.

How a session that is more than 30 minutes is still there. Maybe I don't understand this message correctly. Check whether you session-timeout is really set correctly. You can set the timeout in the default web.xml for all apps, but you could override it in the webapps web.xml, too. Maybe there it's still set too high. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Because if you want to configure a JNDI Datasource and use Tomcats Jakarta Commons DBCP connection pool there's "no" other way then placing the .jar into common/lib because Tomcat itself requires the classes already, not only your webapps. Moreover you should make sure that the webapps don't contain the driver.jar in that case again. Otherwise you'll face lot's of funny classloading issues... E.g. if you work with driver specific data types you could face problems like "instanceof" returning false although using the same class because objects might be loaded by different classloaders (and instanceof and casting only works within the same classloader).

Just run my junitreport via ant which also dumps lots of system properties, too: "java.vm.name" is what you are looking for, e.g. java.runtime.name Java(TM) 2 Runtime Environment, Standard Edition java.runtime.version1.4.2_05-b04 java.specification.name Java Platform API Specification java.specification.vendor Sun Microsystems Inc. java.specification.version 1.4 java.util.prefs.PreferencesFactory java.util.prefs.WindowsPreferencesFactory java.vendor Sun Microsystems Inc. java.vendor.url http://java.sun.com/ java.vendor.url.bug http://java.sun.com/cgi-bin/bugreport.cgi java.version1.4.2_05 java.vm.infomixed mode java.vm.nameJava HotSpot(TM) Client VM java.vm.specification.name Java Virtual Machine Specification java.vm.specification.vendorSun Microsystems Inc. java.vm.specification.version 1.0 java.vm.vendor Sun Microsystems Inc. java.vm.version 1.4.2_05-b04 Hence you should be able to distinguish the Client VM vs. Server VM with a simple JSP printing those properties.

I'd try java.lang.System.getProperties() or something... At least on a Solaris machine you could figure out whether you are running in 32bit or 64bit (triggered by -server) mode by checking os.arch as it differs. Probably there are other sys properties giving a hint (see javadoc). Also the manager app shows this along with you memory settings. Hence you could "assume" that it worked, if you also set -Xmx or Xms and check this changing with the Tomcat manager app. Cheers, Michael - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Common vs. Shared
I am quite sure this has been asked and answered but I googled a bunch of combinations and didn’t find the answer, so I am sure someone here will know and share. What is the difference between the /common/ and /shared/ I understand this is a class loader issue, and I have read the comments in catalina.properties. What would go into ‘common’ that wouldn’t go into ‘shared’ and vice versa? If a jar is in /common/lib/ and a different version of that jar is in /shared/lib/ what will be the effect? Similarly, if I modify catalina.properties and add something to ‘common’ that is already in ‘shared’, etc. Understanding the relationship between ‘common’ and ‘shared’ and the intended use thereof should be of interest to more than just me.

I guess a "JAR redeployment" is not really feasible or a good solution. You should better reconsider if it's a good idea to place files that get modified over and over into a jar at all and especially into shared/lib. Can't you place the xml files somewhere else? If you really need it in this jar, you might still load it on a file basis instead of classpath resource basis (e.g. unjar the jar file yourself and read the xml file instead of relying on the classloader) > > Any help you can provide me will be well appreciated. . > > Thanks. > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
