Could this be rela ted to me running Tomcat in process with IIS? No, I don't think it's related to IIS. We encounter the same problem on several installations of Apache+Tomcat. I assume that maybe there is an influence of used JDK -- on installations with Sun's JDK1.3 this failure is rather rare; using IBM's JDK1.3 it's more or less common sense. Anybody out there with similar observations? Br, Martin Exler

mod_jk and new HTTP methods
Hi, as it seems, mod_jk has a set of predefined HTTP methods it can exchange between Apache and tomcat. This is rather unfortunate since I am implementing a WebDAV server and WebDAV introduces a range of new HTTP methods. Whom would I best talk to regarding extending mod_jk to be able to handle unknown methods as well? Stefan

Re: Tomcat in production
I have 2 Intel dual CPU NEC 5800 machines on production since last 3 months with Tomcat 3.2 on win2k with iis 5.0 and MSSQL 7.0, so far no complaints, no crashes, better performance compared to Coldfusion 4.5 I have an unscientific success story, in that Tomcat has treated me well in my small business environment. I can not give you actual stats. But for one project I have, I have about 20-25 servlets and jsp's that take about 45,000 hits over the course of a month. I've never had any complaints about speed or anything (of course, there are many variables in the speed equation, but Tomcat has not presented me with a weak link in my setup). That's about as un-scientific as you can get, but it's what I have to offer. BTW, my config is apache/tomcat/mysql on a dual PIII-600 over a 384K line. I have not used any other container, so I can not compare any other engine directly.

How do I do an SSL handshake from a Java Servlet ?
I've got to write a java servlet to Login to a website which uses SSL. When you look at the web page that does the log on, the form uses a post. I create the url url = (URL) new URL(https://www.nxtrains.co.uk/NASApp/Neg/RoutingControl;); then set up a connection HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(); conn.setRequestMethod(POST); conn.setDoOutput(true); conn.setDoInput(true); conn.setRequestProperty(Content-Length, +postData.length()); Then do the connect conn.connect(); OutputStreamWriter os = new OutputStreamWriter(conn.getOutputStream()); os.write(postData, 0, postData.length()); os.flush(); os.close(); But it isn't returning the screen which confirms the log on. Do I need to do an SSL handshake first, and if so what does it look like ? Thanks David

RE: Bean Choices (code question)
Title: RE: Bean Choices (code question)
there is no gc on static objects. static objects(methods,fields, or classes) are created once on startup and there is only one instance of the method or field ever created that all requestors to your class will use. But with Tomcat I do believe that if you have the same class in 2 different contexts, that it will load two separate instances of your bean due to the different class loaders.
This also means that if you are writing to the static fields on the first(or any) call, make sure to synchronize the write, in case 2 calls occur at the same time.

Yeah, I know, but it's tempting to write all the methods as public static.
Then I don't have to create the object at all, but I don't know the affects

If you make the bean class have a private constructor and a static
reference
to an instance of its own class, then there will always be a strong
reference from the class itself to the instance of the class. (The first
call to bean.getInstance() instantiates the private static member variable
which is your singleton instance of your bean, the contructor does the db
work etc.)
Therefore, it won't get gc'd.
That's the way I do my classes that do that kind of stuff, anyway.

Subject: Bean Choices (code question)
I'm sorry if this is a little off-topic, since it is more about java code,
but I thought Tomcat users would be interested/knowledgeable about the way
beans work.
I have a lot of informational beans that hold static reference data (think
ISO codes, State abbreviations, etc...) With these types of beans, I have
the choice of instantiating a singleton object reference to the bean and
accessing the methods through the object, or making all the methods
public
static so I can access them via BeanName.method(). For the former, the
bean
does all of it's initialization and database access in it's constructor
and
my JSP's have something like the following at the top:
%!
private static BeanName bean = BeanName.getInstance();
%
For the latter, the bean does all of it's initialization and database
access
in a static block:
static {
// bean initialization and DB access
}
and my JSPs reference the static methods:
%= BeanName.method() %
My question concerns the way beans with all public static methods are
instantiated and garbage collected. Because these beans hold unchanging
reference info, I only want the data loaded from the database once the
first
time the bean is referenced. For beans with all public static methods,
since there are no object references to them, when are they garbage
collected? Is it possible that the bean will be unloaded and the code in
my
static block will be re-run when the bean is next referenced? Or do these
all static objects somehow stick around forever? For the singleton, I know
the object will last as long as the JSP is loaded, because there is a
definite object reference to the singleton. I'm a little unclear as to
what
happens with a bean that has all public static methods, though.
Can anyone shed some light on this?
Thanks,
--jeff

Tomcat: NT Service doesn't automatically load context classes and Jars
As I understand the Tomcat NT wrapper, all configuration for the NT Service version of Tomcat is obtained from the wrapper.properties files. Does this also mean that I must add to the wrapper.classpath any classes and jar files that are needed? When I run the Tomcat server in normal mode, it scans the WEB-INF/classes and WEB-INF/lib directories under a context and automatically makes available any jar and class files that it finds in those directories.

Images don't show using default directory
I am running Jakarta Tomcat 3.2.1 on Windows 2000. I have created a directory that contains some JPGs. Some of them have spaces in the name, some of them do not. I point my browser at the directory: http://192.1.1.1/testdirectory/ and let Tomcat build the directory page. I see the list of files. However, if I click on one of the images with a space in the name, it does not show up. I see Tomcat successfully replace the space with a %20 in the URL, but the image does not show up. If I click on one of the images with no spaces in the name, it does successfully load. I know all of the images are valid graphics and can see them outside of the website. Is there any settings I am missing? Has anyone else seen this? Is this a 2000 thing? Thanks, Eric Lubin [EMAIL PROTECTED]

Servlet Placement

I created a HelloWorld servlet and placed it in the D:\tomcat\jakarta-tomcat-3.2.2b2\webapps\ROOT\WEB-INF\classes and also set my ENV on NT for the servlet.jar and jasper and I CAN YES compile and all is well. In my browser if I call http://localhost:8080/servlet/HelloWorld all is good. So now I created a directory under classes called coreservlets and moved that HelloWorld.java file into there, added the package coreservlets; at the top of the file, recompiled the file (that went well) but I can't get it to show up in the browser. I tried http://localhost:8080/servlet/HelloWorld that does not work. http://localhost:8080/servlet/coreservlet and that does not work.?

I did that here (maybe I'm not using the same version than you) but it's the
line in
/usr/local/build/tomcat/conf/server.xml:
Parameter name=handler value=org.apache.tomcat.service.http.Http

Parameter name=port value=8080/
which you have to change to 80 or vice versa.

mapping servlets
I just upgraded from jserv to Tomcat. I used to have my servlets under /bin instead of /servlet with: ApJServMount /bin /root I still want to use these servlets under Tomcat. But I am struggling a bit to configure it. One method I tried was creating a context called bin under webapps. Then in the web.xml file I put in: web-app servlet-mapping servlet-name invoker /servlet-name url-pattern * /url-pattern /servlet-mapping /web-app but this didn't work. I tried also putting in : ApJServMount /bin /root in the .conf file and then modifying the default web.xml file to use invoker for /bin/* I know this is trivial! Anyhelp would be appreciated.

Jikes for JSP's
Avid Tomcat-ers, Is Jikes 1.14 compatible with j2re1.3.0_02? Also, aside from rebuilding jakarta-tomcat-3.2.1, is there a simpler way to deploy JSP's without requiring a JDK? One posting to the archives referred to a tc3.JasperOptions interceptor, but I cannot locate such a class. How does one pre-compile JSP's for deployment? Can they be packaged in a .war file? Thanks
Contexts, Classes, Variables

To use URLRewriting with Tomcat 3.2.1
Hi all, I am using Tomcat 3.2.1 with Apache 1.3 and I have the following problem:Perhaps that has been asked before, but I am not sure I want to rewrite a path from a form like 'http://host:port/file.html' to something like 'http://host:port/ContextServlet/MyServletName?parameter=file.html'). (Note that the program works when i use the second URL form in the browser). So that, as it seems that Tomcat doesn't want to use .htaccess file, I decided to write the following instructions: LoadModule rewrite_module module/mod_rewrite.dll IfModule mod_rewrite.c RewriteEngine On RewriteBase /ContextServlet/ RewriteRule ^file.html /ContextServlet/MyServletName?parameter=file.html. /IfModule in tomcat.conf or server.xml but with no result. Any help will be greatly appreciate. Enjoy the rest of the day.

Threads
I'm doing performance testing of an application for Tomcat 3.2.1. Basically a client application accesses a service running in Tomcat/Jboss using SOAP. I have a test client that generates X number of threads to access the URL/Tomcat port(8080). The problem is that when X is greater than 15, I get connection refused. After more testing, I found that there seems to be a maximum of 15 connections per second limit. I don't think this is true, but the behavior seems to support this theory. I used the same test client to access the apache port and it supports hundreds of simultaneous connections. Is there some configuration I need to change? Is this a know limit? Any help would be appreciated. Han

RE: javax.xml.parsers.* not found

I have found that even pointing to the directory containing my .jar files sometimes do not work and instead I have to explicitly add the .jar file to the classpath( eg.. c:\classpath;. doesn't work but c:\classpath\archive.jar will work). I would try appending the xalan.jar, crimson.jar, etc.. to your classpath. One other important thing is to make sure you add these paths to the front of your classpath and not the end, you could very well have another (possibly outdated)copy of xalan.jar for instance in another directory that is searched first in your classpath and don't forget to add . current directory if your working directory contains the .jar files you want to use.

Re: RequestDispatcher.forward()
Check out the HttpMessage and HttpsMessage classes in the
com.oreilly.servlet package available from Jason Hunter at www.servlets.com.
Does the same basic connection stuff and returns an InputStream which you
can wrap in a BufferedReader like Eric does below. The nice thing is that it
does secure ssl (https) connections also with the JSSE jar files -- and it's
very easy to setup and use.

were loaded once and never unloaded, but I wasn't sure.
On the same subject, are class constructors called when static methods are
accessed? Right now, in my all static method classes, I'm doing my
initialization in static blocks. I'm wondering if I can move that
initialization into the class constructor, but I'm not sure if/when the
constructor is called when a static method is called.
Any insight on this point, also, is greatly appreciated.
Thanks,
--jeff

Subject: RE: Bean Choices (code question)
there is no gc on static objects. static objects(methods,fields, or
classes)
are created once on startup and there is only one instance of the method
or
field ever created that all requestors to your class will use. But with
Tomcat I do believe that if you have the same class in 2 different
contexts,
that it will load two separate instances of your bean due to the different
class loaders.
This also means that if you are writing to the static fields on the
first(or
any) call, make sure to synchronize the write, in case 2 calls occur at
the
same time.

Yeah, I know, but it's tempting to write all the methods as public
static.
Then I don't have to create the object at all, but I don't know the
affects
on garbage collection.

If you make the bean class have a private constructor and a static
reference
to an instance of its own class, then there will always be a strong
reference from the class itself to the instance of the class. (The
first
call to bean.getInstance() instantiates the private static member
variable
which is your singleton instance of your bean, the contructor does the
db
work etc.)
Therefore, it won't get gc'd.
That's the way I do my classes that do that kind of stuff, anyway.

Subject: Bean Choices (code question)
I'm sorry if this is a little off-topic, since it is more about java
code,
but I thought Tomcat users would be interested/knowledgeable about the
way
beans work.
I have a lot of informational beans that hold static reference data
(think
ISO codes, State abbreviations, etc...) With these types of beans, I
have
the choice of instantiating a singleton object reference to the bean and
accessing the methods through the object, or making all the methods
public
static so I can access them via BeanName.method(). For the former, the
bean
does all of it's initialization and database access in it's constructor
and
my JSP's have something like the following at the top:
%!
private static BeanName bean = BeanName.getInstance();
%
For the latter, the bean does all of it's initialization and database
access
in a static block:
static {
// bean initialization and DB access
}
and my JSPs reference the static methods:
%= BeanName.method() %
My question concerns the way beans with all public static methods are
instantiated and garbage collected. Because these beans hold unchanging
reference info, I only want the data loaded from the database once the
first
time the bean is referenced. For beans with all public static methods,
since there are no object references to them, when are they garbage
collected? Is it possible that the bean will be unloaded and the code in
my
static block will be re-run when the bean is next referenced? Or do
these
all static objects somehow stick around forever? For the singleton, I
know
the object will last as long as the JSP is loaded, because there is a
definite object reference to the singleton. I'm a little unclear as to
what
happens with a bean that has all public static methods, though.
Can anyone shed some light on this?
Thanks,

Problems upgrading Tomcat with JAXP 1.1

Tomcat-Apache configuration
Hello, I've installed Tomcat3.2.1 over RedHat 7.0 and followed the steps recommended in the Jakarta web page but Tomcat doesn't work. I think I've made something wrong with the mod_jserv.so file because all the error messages deal with it. First of all I made it using apxs as it's said in the user guide but when I restart Apache after having restarted Tomcat I get an error message that says something like mod_jserv.so doesn't seem to be a DSO module. Then I tried to recompile Apache, I did the following: #./configure --prefix=/usr/local/apache --enable- module=rewrite --enable-shared=rewrite --enable- module=proxy --enable-shared=proxy --enable-module=so then added: #./configure --add- module=/usr/local/apache/libexec/mod_jserv.c #make install then I copied the built mod_jserv.so file from /usr/lib/apache/ to /usr/local/apache/libexec/ and when I tried to start Apache I got: Syntax error on line 1 of /usr/local/tomcat/conf/tomcat- apache.conf: Cannot load /usr/local/apache/libexec/mod_jserv.so into server:undefined symbol: jserv_error_exit ./apachectl start:httpd could not be started Finally I tried copying a prebuilt mod_jserv.so file I downloaded from the web in .../apache/libexec/ but I received this message again: API module structure 'jserv_module' in file /usr/local/apache/libexec/mod_jserv.so is garbled - perhaps this is not an Apache module DSO? I think I'm not the firstone with this problem, if someone could tell me what to do (copy files, edit another ones, re-configure packages, etc) I would thank him/her very much. Thanks in advance... Best regards. Renato

ServletConfig question on Tomcat
Hello And Happy Friday to all.
I am working out of Marty's Core Servlets book and I am having trouble
getting an init statement to work.
For those that have the book it is on page 40. If you don't have the book, I
will try and explain it here.
The code below is suposed to look at the web.xml file for some init
parameters. According to the book the web.xml file is to be placed in the
/installdir/webpages/WEB-INF and the file just lists param names and values.
And according to the book, when a servlet gets called and it has the
following method
public void init(ServletConfig config)
super.init(config);
message = config.getInitParameter(message);
that this init gets called just once, and all subsequent hits of this are
threaded. So its a one time initialization.
I have the web.xml file filled out properly and I have my class file in the
/installdir/webapps/root/web-inf/classes/coreservlets and I marked my code
with package coreservlets. All works, it just does not go out and get the
web.xml file for my info.
Below is all the code, you can try and run it, if you like. It looks kind of
cool, and I would like to get it to run.
If anyone understands, or knows of a missing config in my setup, please let
me know.
Thanks
Scott Purcell

Re: ServletConfig question on Tomcat
Try to put your servlet directly under Web-inf/classes instead of put it in your pkg coreservlets. See if it works. As my exp, I usually create the package under webapps, then Web-inf/classes is directly under that directory. All servlets are placed under classes. then go to URL: localhost:8080/pkg_name/servlet/servlet-name I think I had a similar problem when not putting a servlet in the class directory but in another dir which is under class dir.

jsp:include page=%=servletPath% flush=true|false/ errors
Hey, guys,
I am new to tomcat... using Tomcat v4.0-b3/b5.
I am trying to include other jsps output in one main jsp and getting an
IllegalStateException: with error message:
Cannot forward after response has been committed.
This is what I am doing:
% for(int i = 0; i typeNames.length; i++) {
url = my url is constructed here; %
jsp:include page=%=url% flush=true // if I set the
flush to false I see the first iterated page of the servlet that I am
including, if I am setting it to true then I get exception right on the
first iteration of the loop.
% } %
I am writing JSPs then I am compiling them into servlets by using
jspc.sh script that uses JspC.java in jasper's package. So when I go
into the browser I am accessing not JSPs but converted jsps to Servlets
which were generated by this script. (jspc.sh).
I have tried many different things already, setting isThreadSafe to
FALSE, setting buffer to a very big size, setting autoFlush to TRUE and
FALSE, nothing seems to work.
Has anyone ever encountered such problems?
Thanks for your help,
Oskar

Tomcat: NT Service doesn't automatically load context classes and Jars
As I understand the Tomcat NT wrapper, all configuration for the NT Service version of Tomcat is obtained from the wrapper.properties files. Does this also mean that I must add to the wrapper.classpath any classes and jar files that are needed? When I run the Tomcat server in normal mode, it scans the WEB-INF/classes and WEB-INF/lib directories under a context and automatically makes available any jar and class files that it finds in those directories. The only way I can get the NT service version to work correctly with my context is to add each of my class and jar files into its wrapper.properties file. Is this normal? thanks, ron

realm). Tomcat wouldn't start since it couldn't find the driver so I made
a symbolic link (running on RedHat Linux 6.2) in the
$CATALINA_HOME/common/lib directory to the classes111.jar file from the
Oracle distribution. Is that where the Oracle JDBC driver should be put? I
also tried it in $CATALINA_HOME/lib but that didn't work.
Once the driver was found I had to make a change to the Realm entry itself.
It has
connectionURL=jdbc:oracle:thin:@ntserver:1521:ORCL?user=scott;password=tiger
so I changed the server, SID, username, and password to suite my installation
but Tomcat complained with
java.sql.SQLException: invalid arguments in call
After looking at the JDBCRealm.java source code it seams that it needs the
connectionUser and connectionPassword attributes to be defined (it puts them in
the Properties instance to pass to the connect() call from the open() method).
So I removed the
?user=...;password=...
portion of the connectionURL attribute and added the required two.
Things were shaping as Tomcat can now find the JDBC driver and the Oracle
driver isn't complaining about the connection information. But now I'm getting
another error and this is where
my inexperience with Java security model hinders me. I'm getting the following
exception when Tomcat starts:
java.security.AccessControlException: access denied (java.net.SocketPermission

So I had a look at the catalina.policy file but I'm really not sure what I need
to add. It seems that a DNS resolution is attempted but the security system
denided it. I found the entry:
// These permissions apply to the servlet API classes
// and those that are shared across all class loaders
// located in the common directory
grant codeBase file:${catalina.home}/common/- {
permission java.security.AllPermission;
};
I thought I could add a similar entry like:
grant codeBase file:${catalina.home}/common/lib/- {
permission java.security.AllPermission;
};
but that didn't work.
I would like to start running with the -security flag but this will obviously
stop me in my tracks.
Any help would be appreciated,
Kevin.
