I'm pretty sure that if you use this package in a commerical product, you
have to make sure that each developer using the package has a copy of the
latest O'Reilly book. Check the license carefully.

Whilst the mod_jk worked for me, I aggree that it could be more clearly
marked as to what platforms its currently supported on. As the the number
one issue raised on the list, over the last week or so it seems to be people

session timeouts early sometimes

[David Wall]

It's hard to nail down, but we seem to note that tomcat 3.2.2beta2 will have
a session timeout early sometimes.  Is there a known bug in the session
timing routines?

Thanks,
David

jsp pathinfo

[David Wall]

Is the pathinfo portion of an URL supposed to work 
with JSPs?  In tomcat 3.2.2beta2, I'm using an URL like 
/app/test.jsp/pathinfo, but it's not working (as if tomcat is looking for a JSP 
named 'pathinfo' instead of 'test.jsp' in the 'app' webapp, with the path info 
set to "pathinfo".
 
Do I need to use a regular servlet to make that 
work, or is pathinfo just not supported by 
tomcat?David

Pages never finish loading

[Randy Kreisel]

First off, I am a newbie, so forgive me if this issue is already solved.But 
I could not find a valid resolution in my searches of this group.

When I run the example servlets from my NT workstation at home they 
complete without issue. When I run them from the Win98 machine at home or 
from my NT workstation machine at work they generate and display all the 
output, but the wait cursor continues for several minutes until it finally 
times out. To complicate the issue, if I specify the port (8080) in the url 
on my Win98 (or my daughters Win95) machine, it works correctly, but when I 
do the same thing at work, it behaves as described above. I have not 
modified the example code.

Here is the configuration:
Server -
NT 4.0 server w/sp6a - 266mhz, 64mb Ram, 18 GB hd, 2 network cards
IIS 3.0 (yes, 3.0 works fine other than this problem, and no, I don't want 
to upgrade to IIS 4.0, (it screws up the proxy server))
Tomcat 3.2 - default installation
cable modem
Winproxy (proxy/firewall software, for which I have opened ports 8080 and 
8007 for both incoming and outgoing TCP and UDP)
Internal network on non-routable address range 192.168.255.xxx, is not 
visible to the outside world.

Any assistance would be greatly appreciated. I'm stumped.
Thanks

JDBC Realm - User Roles

[Gary Henson]

I've been trying to 
set up JDBC Realm authentication with Tomcat.
 
I've run into a 
problem when it comes to roles. The user is authenticated alright, but the roles 
do not seem to be 
taken from the 
database. I always get redirected to the error jsp unless I have the user and 
role specified in the
tomcat-users.xml 
file.
 
This is the setup I 
have:
 
** server.xml 
***
 
driverName="oracle.jdbc.driver.OracleDriver" 
connectionURL="jdbc:oracle:thin:@testdbase:1521:TEST" 
connectionName="user" 
connectionPassword="pass" 
userTable="security_user" userNameCol="user_id" 
userCredCol="user_password" 
userRoleTable="security_user_role" roleNameCol="role_name" 
/>
 
All the mentioned 
tables and columns do exist, I've checked a lot.
 
*** web.xml 
***
    
  
 
Secure 
Area 
/secure/*  
  
 
testrole  
    

 
    
  
FORM  
Form-Based Authentication 
Area  
    
/secure/login/login.jsp    
/secure/login/error.jsp  
    

 
As mentioned above, 
this doesn't work unless I also have the following in 
tomcat-users.xml

 
And yes, it works 
without the password being in the file. This suggests to me that the 
username/password is 
being checked 
against the database, but the role against tomcat-users.xml. I'm using Tomcat 
3.2.1 currently
as a stand-alone 
server. Please help, I'm going crazy.
 
Gary.

Re: Tomcat vs. other app servers

[Jeff Kilbride]

It wouldn't surprise me if JRun ran better in a Windows environment. After
all, that's what it was originally designed for. The JRun 1.x series was a
lifesaver for me in late 1997 when we ported all of our Perl code to Java.
That was before we moved to Linux from NT and before there were any
in-process solutions for Perl on NT. Fortunately, back then, you could
actually get the JRun developers on the phone to answer questions if you ran
into problems. Times have changed!

Trivia question -- what was the name of the company that developed JRun and
was eventually bought out by Allaire?
Super Trivia -- who was the CEO and lead developer? (who must've made a
bunch of cash in the buyout...)

Tomcat hangs under win 98 after the line

would be appreciated.

Re: newbie

[Jeff Kilbride]

It depends on your system. If you're running Win98 with 64MB of RAM, and
your servlet has a lot of initialization code, then it might make sense.
Remember, your servlets aren't loaded and initialized until they are called
for the first time. If you want to avoid this type of delay, use the
"load-on-startup" tag inside your "servlet" tag in your web.xml file. There
are examples of this in the main web.xml file in the TOMCAT_HOME/conf
directory. This will load and initialize your servlet when Tomcat starts up
and avoid the first hit delay syndrome.

Re: Tomcat vs. other app servers

[Scott Tatum]

Everything remained the same except swapping JRun with Tomcat.

Sun Enterprise 250 (1 gig RAM)
Solaris 2.7
Apache 1.3.14
Tomcat 3.2.1 (mod_jk)

I liked the nice web interface for JRun setup/admin, but IMO Tomcat has it beat
just about everwhere else.

RE: newbie

I think you're seeing something different, assuming you are using servlets
and not JSP: as others say, JSPs need to be compiled, but servlets don't.

Are you seeing a delay in starting up (i.e., until it stops using CPU), or
in handling the first request?

Javadoc ignores sourcepath

[Chris Nolte]

I am trying to generate Javadoc for a web application I have written.
My build.xml file contains the target:
  

  

However, when I say "build all" or "build javadoc", it appears 
to try to process all files in the application's root directory, 
i.e., one above the "src" directory.  

I am able to compile and run the web application itself, so I
don't think my classpath is screwed up in general.  It is only
javadoc that is failing.

Any suggestions?  I am running Win98 (yes, I am ashamed)
and Tomcat 3.2.1.

Re: newbie

[eric chacon]

This is normal behavior--

The first time, it compiles your JSP into a servlet, and after that, the 
servlet's loaded and ready to go.

When you have a production site running, you might want to call all JSPs 
once every time you deploy so your users won't have to wait the first 
time...

Cheers,
E.

Re: Code Q.

[eric chacon]

Scott,

You're asking some straight-forward Java questions that might be better 
addressed in one of the news groups (comp.lang.java, for example)--if you're 
not familiar with newsgroups check out www.deja.com (currently held hostage 
by google, but hopefully working soon).

In the code, you're defining a class called Hello which is a subclass (also 
called a child) of the HttpServlet class.  Extends is a Java keyword meaning 
that your class (Hello) inherits the functionality of the HttpServlet 
class--Object Oriented concepts like Inheritance would be thouroughly 
explained in a Java text book.

It looks like your doGet method is miss-copied (adding to your confusion).  
You are, in fact, defining a method--one that will eventually be called by 
the Tomcat server.

If you look closely at the book you're reading, you'll probably see that it 
actually takes HttpServletRequest and HttpServletResponse (not just 
HttpServlet).

Servlets are kind of complicated--you might find it easier to start with 
some more basic Java and work up to Tomcat and servlets.

Cheers, and good luck,
Eric

This happens to me with my servlets--some of the time
they take up to 30 seconds to load the first time.
Is this normal behavior also?

Re: newbie

[Anne Dirkse]

Congratulations -- Looks like you set it up correctly.
The lag that you notice the first time you visit a jsp is normal.
What is happening is that JSP is being compiled into a servlet (which is
what JSPs do)
That will only happen the first time you access the JSP (unless you
modify the source.)

multipe instances of tomcat

[time out]

i have read all the documentation on workers and isapi_redirect.dll and the 
minimal user guide and i still don't understand how to get tomcat to run 
multiple instances.

here is what i have:
tomcat 3.2.1
win2k sp1
iis 5.0(the one that comes with win2k)
isapi_redirect.dll

so far i have been able to set up webSiteA (it lives in 
d:\inetpub\webSiteA.) so that iis serves everything except *.jsp.
i did that by installing tomcat in d:\inetpub\tomcat and making a context 
in server.xml that looks like this:
 
 

and adding the following lines to the uriworkermap.properties:
/*.jsp=ajp12
/servlet/*=ajp12
eveything else is the default configuration.


so i have something that works and i am pretty sure that i don't know why 
it worksi can't seem to make all the connections needed to make tomcat 
tun multiple times, once for each web site that i have on the 
machine.  that way if i need to reload classes for one of them, tomcat does 
not have to reload for all of them.

thanks.

Bug in tomcat3.2.1 RecycleBufferedInputStream class - or solution to ContextManager: error reading request:ArrayIndexOutOfBoundsException

[Animesh Chaturvedi - US]

Hi 

Tomcct 3.2.1 does not work with Kaffe JVM. When a request is sent to Tomcat 

you get following error

ContextManager: Error reading request, ignored -
java.lang.ArrayIndexOutOfBoundsException 
at java.lang.System.arraycopy(System.java:native) 
at java.io.BufferedInputStream.read(BufferedInputStream.java:118)

at
org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java:498) 
at java.lang.Thread.run(Thread.java:325) 


After lot of debugging I found that there is bug with
RecycleBufferedInputStream. 
The original RecycleBufferedInputStream class only resets count = 0.
This results sometimes in count to be set to zero and pos is not changed so
it is now greater than count. and 
when yo do a System.arraycopy with length = count -pos. It gets a negative
value hence the array index out of bounds exception. 

So you have to change the two functions in RecycleBufferedInputStream like
this.

public void setInputStream( InputStream is ) {
this.in = is;
this.pos = this.count = 0;
this.markpos = -1;
}

public void recycle() {
this.in = null;
this.pos = this.count = 0;
this.markpos = -1;
}


Now tomcat 3.2.1 works fine with Kaffe VM.

JSPs with extra path info?

[David Wall]

I'm trying to get Tomcat 3.2.2b2 to handle a URL of the format:

http://www.myeastside.com/app/GA.jsp/Test+word.doc?m=1&a=2

The idea is that I expect this to run my JSP called /app/GA.jsp.  It should
have some extra path string of "Test+word.doc" and two parameters that I can
retrieve named "m" and "a".

But when I run it, tomcat's JspEngine keeps bringing up my notfound page.

I run Tomcat with Apache 1.3.19 and mod_jk.so using the AJP13 connector.  I
have mounts like:

JkMount /app/*.jsp ajp13
JkMount /app/servlet/* ajp13

and I even added this just in case...
JkMount /app/*.jsp/* ajp13

I believe it's getting through Apache to TC okay since the jasper log shows:
2001-04-18 05:12:08 - JspEngine --> /notFound.jsp
2001-04-18 05:12:08 -ServletPath: /notFound.jsp
2001-04-18 05:12:08 -   PathInfo: null

And it is bringing up my not found page.  The GA.jsp file is present in the
right area though, right along with my other jsps.

Thanks,
David

Re: Tomcat vs. other app servers

[Jeff Turner]

We have found JRun 3.0 to be a fine product (as was it's 2.3 predecessor), and
use it in many production environments. One should be careful to avoid
unsubstantiated claims on this forum, lest it amount to FUD.

That said, most of our developers use Tomcat for development. It is
spec-compliant, doesn't crash, has excellent support (this list:) and 3.3/4.0
eliminates much classpath pain. By contrast, JRun *extends* the spec, accepting
invalid syntax (like <%= foo; %>) which means JSP authors must constantly be on
guard to avoid portability problems. JRun does not have a tomcat-users
equivalent, thus has effectively no user community. Unless you're a fan of
phone-based support, that doesn't leave one much recourse when help is needed.

http://www.theserverside.com is probably the best forum for JSP/servlet
container comparisons.

The only method whereby I have gotten it to repeatedly work correctly is to
stop Tomcat, blow away the work directory and restart Tomcat.

What would be useful is a method in which Tomcat, upon restart,
automatically compiles all the JSPs in its defined contexts.

RE: Configuring Cold Fusion to run with Tomcat 3.2.1

[Dave Bettin]

Cold Fusion doesn't support Tomcat as a front-end
webserver. I would recommend configuring ColdFusion
with Apache. Once, you are succesful with that, then
configure tomcat with apache. 

The httpd.conf file you keep mentioning is apache not
Tomcat.

acknowledgment from web client

[eric leung]

Hi,
I have a servlet serves files for web browser.

How can I know if the HTTP web browser had:
1) finished download 100% of the file, or;
2) only downloaded 50% of the file then click cancel,
or;
3) only downloaded 70% then reboot the machine

i think the TCP/IP layer (socket) will keep track of
acknowlegament send back from client. but how do i
implement this in my servlet? how do i (servlet) know
how many bytes client had receive? 

I am now using apache + tomcat.  I heard tomcat has
problem getting  acknowlegament from client. since
tomcat is seperated by apache server from client (it's

Re: Tomcat vs. other app servers

[Scott Tatum]

Before using Tomcat, our group had spent several k's on JRun 3.0
application server. We have several Intranet applications that receive
thousands of hits per day. Under JRun we were experiencing daily
lockups. After Service Pack 2 for JRun 3 did not fix the problem, I
tested out Tomcat 3.2.1.

We eventually transitioned all of our jsp/servlet applications from JRun
to Tomcat, and have not had a single lockup since. The Tomcat server
also serves pages faster IMO. JRun does not support servlet reloading
either.
>From my experience, Tomcat has high degrees of performance, scalability,
and especially reliability. The only issue I don't know much about is
security. It is not as much of a concern to us as all of our
applications are Intranet-only.

Tomcat has been rock-solid for us and we hope to use it for all our
future Intranet applications, and are looking forward to a production
release of Tomcat 4.

RE: Configuring Cold Fusion to run with Tomcat 3.2.1

[Jann VanOver]

Oh -- 
so you're not using the Apache web server at all?  
 
I see 
why you're stuck.  CF works well with Apache or IIS as the web 
server.  If you were to have one of these setups and then integrate that 
with Tomcat, it should work for you.  Given your situation,  I guess I 
can't help.

RE: Configuring Cold Fusion to run with Tomcat 3.2.1

Dave's point was that if you get CF running correctly with Apache, Tomcat
shouldn't be an issue.  

If you don't start up Tomcat, does CF work properly with Apache?  If so,
then following Tomcat's instructions to make it work with Apache should do
the task.

RE: Date problem with Tomcat/IIS

Yes!  When you say cal.HOUR_OF_DAY (etc.) you're accessing a CONSTANT in the
calendar object.  

What you want to use is the SimpleDateFormat class.  It will do all that you
need!

Like this:

SimpleDateFormat df = new SimpleDateFormat("dd-MM- hh:mm:ss"); 

then ...

retVal = df.format(dt);

and it's done!

[Purcell, Scott]

Hello, 
I am learning JSP and have done quite a few examples from the Core Servlets
and JSP book. 
I apologize for asking this q here, but I am trying to learn Tomcat and put
my whole picture together, and I figured that
the people on this line, would probably know what these lines mean.
Anyway, I keep typing these few lines but really don't have a grasp of what
they are doing. 
I would really like to understand in a 'Laymans' fashion what I am doing and
what these lines do. 
public class Hello extends HttpServlet { 
//I am assuming that the class Hello, that I am creating 
// is extending HttpServlet class? 
// but what does the extends really mean? 
public void doGet(HttpServlet request, 
HttpServlet response) 
throws ServletException, IOExcedption; 
// It looks like I am creating? or calling? a method here. And am I passing
it the HttpServlet class? 
I am very confused on this, and would enjoy hearing from someone that
wouldn't mind going over that with me. 
Thanks very much, 
Sincerely

The only method whereby I have gotten it to repeatedly work correctly is to

What would be useful is a method in which Tomcat, upon restart,

getSession(false)

[Jason Novotny]

Hi,

I'm using the following snippet in my main servlet:

public void service(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {

HttpSession session = req.getSession(false);
 if (session == null) {
  System.out.println("session is null");
 } else {
  System.out.println("session is not null");
 }

}

what I find is that when I go to the servlet, I first see "session is
null". Fine by me, and since I passed "false" to getSession, I expect
not to have one created. However, when I reload the page, now I get
"session is not null". can anyone please explain why getSession(false)
actually creates a session, or what I might be doing wrong.

Thanks, Jason

Problem response.sendRedirect

[Connie Chan]

Hi,

Does anyone know what response.sendRedirect is supposed to behave?  I'm
developing an object to detect if the session is valid.  All my servlets
would call the function from this object (let say
sessionChecker.checkSession(request, response) ) to check if a valid
session exists.  If there is no session, I call
response.sendRedirect("login.jsp") in this session checker object.
However, I find out that when this line gets executed, the response does
not get redirected right away.  Although I put " return; " after calling
sendRedirect, the handler would return back to my servlet.  My servlet
would continue to execute the logic.  At some point, the response would
get redirected.

Also, in the jsp case, I use jsp:include at the beginning of my jsp
page.  I then check the session by calling the session checker object.
If there's no valid session, the response should get redirected.
However, my jsp page would throw an exception about
java.lang.IllegalStateException: Response has already been committed.  I
need to use include directive, instead of using jsp:include.  Once I
change it, my jsp page works.  But I do need to provide an argument for
the page included.  How should I do it without calling jsp:include?
Please help.



Thanks,
Connie

tomcat 3.2.2b3 mod_jk.log errors

[Pogo Com]

We are testing Tomcat on a very high usage site.  Due to problems with Tomcat
3.2.1, we switched to the 3.2.2 beta versions.  With the latest 3.2.2b3, the
mod_jk.log file contains many messages of the form:

[jk_uri_worker_map.c (184)]: In jk_uri_worker_map_t::uri_worker_map_free, NULL
parameters
[jk_uri_worker_map.c (334)]: jk_uri_worker_map_t::uri_worker_map_close, NULL
parameter
[jk_uri_worker_map.c (184)]: In jk_uri_worker_map_t::uri_worker_map_free, NULL
parameters
[jk_uri_worker_map.c (334)]: jk_uri_worker_map_t::uri_worker_map_close, NULL
parameter

Things seem to be working, but is this a known problem?

Can Sessions be tracked via URL-rewriting?

[Robert Zazueta]

Fresh out of the "box", Tomcat appears to write the jsession ID to the
users cookies exclusively, making those who don;t have cookies turned on
for whatever reasons lose their session.

Is there a way to configure Tomcat so that it writes the jsession via
URL-rewriting for those folks without cookies turned on? Or even just
replaces the jsession cookie with URL-rewriting entirely?

Thanks!

Dumb question: are you sure it isn't expiring due to idle time? Does the session 
get lost in the middle of actively clicking through your application, or only when
you turn your attention to something else?

Other factors: what browser/version/platform, are you crossing to/from HTTP/HTTPS?

init/destroy counter ??

[H.F.N. den Boer]

A slight "problem" with some static variables.
There are a number of servlet apps on my webserver.
With one servlet, I can check the status.
However, it seems the initial values of the static variables are reported, also
when I know for sure that I have one or more instances "in the air".

I'm working with;
Win2K server, build 5.00.2195
IIS 5.0, configured with ISAPI filter
JDK1.3.1beta
Tomcat 3.2.1 running as NT service

Below the code of the servlet.

Any ideas ?

Nico

public class SrvltA extends SrvltApp {
  private static boolean accessible = true;
  private static int instances = 0;

  public void init(ServletConfig config) throws ServletException {
super.init(config);
instances++;
  }

  public void destroy() {
if (instances > 0)  instances--;
if (instances == 0) DbAccess.getDbAccess().dbDisconnect();
super.destroy();
  }

  public static void setAccessible(boolean newAccessible) {
accessible = newAccessible;
  }

  public static boolean isAccessible() {
return accessible;
  }

  public static int getInstances() {
return instances;
  }
}

Date problem with Tomcat/IIS

One of them is to get the prefix string for a custom servlet-log.

In the generated string, the date is correct but the time is always the same.
Example of return value: 18-04-2001 11:12:13 

I'm working with;
Win2K server, build 5.00.2195
IIS 5.0, configured with ISAPI filter
JDK1.3.1beta
Tomcat 3.2.1 running as NT service

Below the code of the servlet.

Any ideas ?

Nico

  public String getLogDateTime() {
StringBuffer retVal = new StringBuffer("");
Date dt = new Date();
cal = Calendar.getInstance();
cal.setTime(dt);

retVal.append(getDateOnlyNumbers(dt));  // add date
retVal.append(" ");
retVal.append(cal.HOUR_OF_DAY); // add hour

Set an environment variable called JAVA_COMPILER to NONE.

Re: getInputStream

[Jeff Kilbride]

Hi Georges,

There is a very easy to use class for doing file uploads available from
Jason Hunter, who wrote the original oreilly book on servlets, at his
website:

http://www.servlets.com/

Look for the com.oreilly.servlet package. I think it will greatly simplify
what you are trying to do. There's a good deal of documentation available on
the site.

Thanks,

Re: setting up tomcat and apache to run together

[Jeff Kilbride]

The other problem is that there are very few informative links on either the
Jakarta or the Tomcat sites. Do you realize that there is no link to the
documentation anywhere? (or if it's there, it's impossible to find...) There
are links to the FAQ, to the servlet spec and API, to the sun jsp pages,
etc... but no link to the Tomcat documentation. Also, I just found out a few
days ago that rpms are available for most Tomcat installs. However, if you
don't know where to look for them on the Jakarta site, you'll never find
them because there aren't any links to them.

Isn't that a little odd?

I'll see your 3 cents and raise you a penny...

Re: mod_jk - DEAD END! [POSTSCRIPT]

[Jeff Kilbride]

Forgive the expression, but bullshit. :)

The mod_jk compilation *is* trivial and since they don't list on the website
what version of Apache or Linux the binary is compiled for, it's pretty much
useless. I'd say the number one problem post I have seen since joining this
list relates to the fact that the binary doesn't work on most people's
systems. If you give somebody with relatively little experience a binary
that's supposed to work and it doesn't, it only confuses the matter that
much more.

By the way, I'd be interested in hearing what your config is, since it
worked for you.

AW: losing track of sessions

[Tassilo Pilati]

Interesting... are you using Apache ? I`m running Tomcat 3.2.1 with 
Apache. When I use URL rewritting I run into problems becuase Apache does not 
passover the requests to Tomcat. It gets confused with the ;jsessionid string 
which Tomcat appends to an url to enforce session tracking using url rewritting. 
Do you use virtual hosts ? Have you inserted any rewrite rules into the 
http.conf of Apache ?

You are getting "Compiled Code" because the JIT engine has compiled
your code into machine native format and it can't trace back to a line of
.java code.  I thought there was a command line option like -nojit, but
checking just now I can't seem to remember how to figure it out.

There are two common ways to find out where your problem is:
1.  Add lots of println statements (you error is in the doGet
method, so hopefully that method just calls lots of other methods and its
code isn't to long)
2.  Run Tomcat in a debugger (its Java so it can be done, but its
very slow)

RE: Servlet jar files

[DONNIE HALE]

Bear in mind that the unpacking of .war files is an implementation detail of Tomcat 
and is thus non-portable. Tomcat 4.0 has an option to not unpack the .war file but to 
execute directly from the .war file. WebSphere can deploy a .war file but unpacks it 
into a somewhat different directory structure. I don't know how other servlet engines 
handle this.

If you want to be able to edit property files and redeploy, you need to make it as 
simple as possible to recreate the .war file.

The WAR file doesn't stay packed. It is simply a deployment mechanism.
At startup Tomcat will take any WAR file that it finds in the webapps 
directory, and unpack it
into a directory which has the name of the WAR file.
For example, lets say that you have an existing context called "oldContext".
If you navigate to that directory, you can then jar everything up into a 
WAR file using
the command "jar cvf newContext.war *".
If you take "newContext.war" and move it down into the webapps directory,
and then restart Tomcat, you will end up with a "newContext" directory
within the webapps directory. Within the webapps directory, you should see:

newContext.war
newContext directory
oldContext directory

Nothing prevents your clients from making changes to files that were 
previously located within the WAR file.
Bear in mind that the deployment only works if there was no pre-existing 
"newContext"
directory on the target machine.
If you previously installed release 1 of your application, and now you want 
to install release 1.1
with the same context name, you will
need to remove the context directory tree if you are deploying a WAR file.

The only method whereby I have gotten it to repeatedly work correctly is to

What would be useful is a method in which Tomcat, upon restart,

Re: How to read property files?

[estutes]

Thanks all that answered.
I tried several of the suggestions, and here is what I finally came up
with that works for me. I think it is portable enough to use in most
any tomcat situation.

File pf = new File(request.getRealPath("/myapp.properties"));
BufferedInputStream is = new BufferedInputStream(new FileInputStream(pf));
Properties p = new Properties();
try {
 p.load(is);
} catch ( java.io.IOException e ) {
out.print("Can't load the properties file");
return;
}

Nothing prevents your clients from making changes to files that were 
previously located within the WAR file.
Bear in mind that the deployment only works if there was no pre-existing 
"newContext"
directory on the target machine.
If you previously installed release 1 of your application, and now you want 
to install release 1.1
with the same context name, you will
need to remove the context directory tree if you are deploying a WAR file.

RE: getting line numbers instead of (compiled code)

[Randy Layman]

You are getting "Compiled Code" because the JIT engine has compiled
your code into machine native format and it can't trace back to a line of
.java code.  I thought there was a command line option like -nojit, but
checking just now I can't seem to remember how to figure it out.

There are two common ways to find out where your problem is:
1.  Add lots of println statements (you error is in the doGet
method, so hopefully that method just calls lots of other methods and its
code isn't to long)
2.  Run Tomcat in a debugger (its Java so it can be done, but its
very slow)

My jasper.log file only says what the scratch directory is, and not to

AW: worker.properties

[Tassilo Pilati]

Well, this file is in the conf directory of my tomcat installation. But I
don`t get an error message

The workers.properties file configures the worker threads that take requests
for servlets/jsp's from apache and processes them appropirately. As such,
when running Tomcat without Apache it will have no effect. You only need to
edit this file when you run Apache and Tomcat together. Infact you'll get a
syntax error on a non-PC platform if you forget to edit this file and try
and include it in the Apache directives. See the workers.properties howto
for more information (its in the Tomcat docs somewhere).

AW: Tomcat with Apache/URLRewritting and mod_rewrite

[Tassilo Pilati]

I`m using mod_jk and apj13, however I tried apj12 as well but it should not
make a difference. Tomcat version is 3.2.1. You probably set the noCookies
parameter to false. Then session tracking is implemented using Cookies and
it probably will work. If you set it to false, then session tracking via URL
rewritting is used instead and you should run into the problem I have. Do
you have the string ";jsessionid=" in you urls, when you are using session
tracking ? You probably don`t...

Just to clarify, are you using jserv or mod_jk? And if you are using mod_jk,
are you using the ajpv13 protocl for connection? I'm using mod_jk and
ajpv13, and am session tracking using the HttpSesession class and it works
fine, as does parameter passing. I don't know too much about URL reqritting
though.

Help with refreshing servletContext please.

[Alex Colic]

Hi,

I am implementing a method of caching lists that I want available to all my
web users. I place lists in the servletcontext via:

context.setAttribute("storeroomList",storerooms );

When the lists change I recall my cachelist method which gets the new data
and then put the list back into the session using the above line of code. I
thought that would replace the present list with the new one but
that is not occurring.

Is there another way I am supposed to be replacing attributes?

I thought about using removeAttribute followed by setAttribute but I am
worrying that someone might be accessing a page might need a list just as I
removing the list.

To test the problem I opened up a web page populated with my list and then
went to the database and changed some values in the list. My program then
caught these
changes, and repopulated the lists and then placed them in the context
again. I then opened up another window and the page was populated with the
old data.

Any help in this matter is appreciated.

Alex

RE: Servlet jar files

Title: RE: Servlet jar files



What I 
mean is that our servlet uses property files to determine various 
configuration parameters (logging levels, connection pooling, etc).  If I 
put these property files in the WAR,  how do they edit 
them?

  You mean that you deploy servlets on customers

  I suspect you'd have to edit the tomcat.policy file to relax the security

apache virtual Hosting with tomcat

Hi, I am using unix apache to do virtual hosting. I have recently added
tomcat and trying to configure virtual hosting. Is there anybody on the list

I am failing to load servlet from virtual site.
