[Vijay Suryawanshi]

Hi,
How to use text/vnd.wap.wml MIME Type to serve WML 
pages from Tomkat ? It's not working after putting mime type mappings in 
web.xml. This is similar problem that Raf

eteks PJA, BufferedImage.createGraphics() problem

[Nick Didkovsky]

Hello,
A while back I asked about the getToolkit() problem I was experiencing
with Tomcat under Solaris, Java 1.2.2.  I was pointed toward eteks'
PJA classes which provide a "pure" Java display substitute for XWindows. 
Xvfb was also suggested, which has caused many intermittent problems, so
I am looking instead at PJA.
SUCCESS:
I have since installed PJA and am now starting tomcat with the PJA-specific
options added.  I even suffered the "ugly fix" for the buggy sun.java2d.SunGraphicsEnvironment.class
to get it to run.
Here's my tomcat start command
$JAVACMD -Xbootclasspath/p:../pja/lib/pja.jar:../pja/lib/rtgraphics.jar 
-Dawt.toolkit=com.eteks.awt.PJAToolkit -Djava2d.font.usePlatformFont=false
-Djava.awt.graphicsenv=com.eteks.java2d.PJAGraphicsEnvironment -Djava.awt.fonts=/usr/java1.2/jre/lib/fonts
-Duser.home=/usr/local/jakarta-tomcat-3.2.1/pja $TOMCAT_OPTS -Dtomcat.home=${TOMCAT_HOME} 
org.apache.tomcat.startup.Tomcat "$@" &
The toolkit problem has disappeared.  Hooray.
PROBLEM:
A new problem has appeared, in code where I am trying to create a Jpeg
output stream from an int[] buffer, using JPEGImageEncoder, which requires
creating an image and drawing it into a Graphics2d object pulled from a
BufferedImage.  The following code fails at the createGraphics() line.
Image im = Toolkit.getDefaultToolkit().createImage(new MemoryImageSource(w,
h, buffer, 0, w));    // ok
BufferedImage bi =  new BufferedImage(w, h, BufferedImage.TYPE_INT_BGR);   
// ok
Graphics2D g = bi.createGraphics();    // dies
 
I have burned many hours on this so far.  This only fails on Solaris
- heavily and successfully tested under Windows. Does anyone have any suggestions?
Best,
Nick
PS I ran PJAToolkitDemo and successfully got the few gifs written to
disk, except the ones with fonts, which failed, complaining about no .pjaf
files.  Not supposed to need them in Java 1.2.2... anyway...

Tomcat Mod_jk and NFC Chat

[Juan Alberto Cirez]

Hello to all.
I am new to this list and to tomcat as well (I come from an apache
background).
I have the following questions:
I am trying to setup Apache to work with TomCat w/mod_jk to work with
NFC Chat Server.
My apache configuration files are located on /web/apache-conf
I start the server with the following command
/path/to/binary/httpd -f /web/apache-conf/httpd.conf

I have include directive so apache includes the tomcat-apache-conf-auto
file in its configuration.
By the way, how do I tell tomcat to look for mod_jk.so in
/path/to/apache/libexec rather than the server's root?

I want to include the configuration for Tomcat in /web/tomcat-conf
How do I start TomCat so it uses this location for all its configuration
file?

I also wat to include the configuration for the NFC Server in
/web/nfc_chat-conf
How do I start the chat server so it uses this configuration file...?

Help, please

RE: QuickSorting Vectors

[Craig O'Brien]

Vlad and I were thinking along the same lines.  This is easy but may not be
the best for commercial applications.

Here is a simple program I just wrote:

class CraigsVectorSort  {

Vector vec = new Vector();

public static void main(String[] args)  {
CraigsVectorSort v = new CraigsVectorSort();
v.arraySimpleSort();
}

void arraySimpleSort()  {
vec.add(new String("abbot"));
vec.add(new String("silium"));
vec.add(new String("randy"));
vec.add(new String("goofy"));
vec.add(new String("zenia"));
vec.add(new String("pokie"));
vec.add(new String("xylaphone"));
vec.add(new String("dogface"));
vec.add(new String("friggen-joe"));
vec.add(new String("penuckle"));
vec.add(new String("charlie"));
vec.add(new String("manna"));

System.out.println("before: " + vec);
Object[] obArr = vec.toArray();
Arrays.sort(obArr);
vec.removeAllElements();
for (int i = 0; i < obArr.length; i++)  {
vec.add(obArr[i]);
}
obArr = null;
System.out.println("after :0) : " + vec);
}
}

It works efficiently.  You may want to consider using one of the collections
rather then Vector.  You may not need the synchronization so an ArrayList
would be faster.  Many many considerations.

Let me know what you think.

Craig O'Brien

Don't have a sample but you can
take a look at the java.util.Arrays's sort(Object[]) method.
May be you can use that in combination with Vector.toArray()
which calls System.arraycopy, so this should be fast, may be
even faster than iterating over Vector's elements during
custom sort if you decide to sort Vectors directly.

Re: QuickSorting Vectors

[Fernando Padilla]

I know you asked for Vector, but if you could use the Collection classes (
Java2, java.util.Collection, java.util.List, etc ), you can look at
java.util.Collections for some sorting methods

though it's not quicksort, they claim n log(n) ..

install error: "Cannot use classic compiler"

[Mark Johnson]

I keep getting this error message while installing ant, servletapi,
tomcat on a machine running Debian (upgraded from slink to potato) with
the IBM Java2 SDK. My PATH includes $JAVA_HOME/bin, where javac resides.

mybox:# java -version
java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0)
Classic VM (build 1.3.0, J2RE 1.3.0 IBM build cx130-20001124 (JIT
enabled: jitc))

Here's what's odd. I ran './bootstrap.sh' in the ant directory, and the
build failed with: "Cannot use classic compiler, as it is not
available". AT the end of my rope, I reinstalled the SDK: ant
bootstrapped successfully! I immediately tried './build dist' in the
servletapi (3.2) src directory, and got the same error: "Cannot use
classic compiler, as it is not available".

I've tried changing the 
line in build.xml, disabling the jit compiler, etc, to no avail.

I installed the same setup on another machine with no problems. The only
differences I can identify are:
1. The working installation's IBM J2RE build is earlier: cx1302623
2. The working installation had a fresh Debian potato install (no
upgrade), and perl 5.005 instead of perl 5.004.

TIA, Mark

RE: Relative Pathing and SSL

[Stefán F. Stefánsson]

I wouldn't imagine that you would.  The thing is that tomcat is
generating the redirection.  The default is of course to append http to
the start and if the thing is on some weird port then it has to do :xxx
where xxx is the port number (in your case 443).

Open your server.xml file.  Look for the AJP12 connector which should
look something like this:






It may be different... I don't know.  Try adding the line  to the  tag (right before the
 line.

As I said, I have no idea if this will do the trick but it's worth the
shot.  Let me know how it goes.

Hello all, I'm having an interesting problem persisting an SSL
connection
with my Java servlets.  I am using Windows NT/IIS with Tomcat acting
only as
the servlet container (with the isapi_redirect.dll).  Everything works
fine
except when I need to re-direct a user from the servlet back to any
other
page.  When that happens, for some reason it sets the url to http
instead of
https and then adds a colon with port 443 following the url (which is
obviously the port that it should be on, only automatically using the
https
prefix).  

Example:
Should be: https://www.myserver.com/Test.htm
Instead it gives: http:www.myserver.com:443/Test.htm

I have no idea why this is happening.  I can't find any methods for the
HttpServletResponse object that allows me to set the communication
protocol
etc etc.  Here is the line of code that I'm using:
response.sendRedirect("../../Test.htm");
Notice I am using a relative path.  If I use this instead.
response.sendRedirect("https://www.myserver.com/Test.htm");
then it works.  I hate to hard code the url like that though because I
have
a development server and a production server.  I'm at a loss.  Anyone?

Re: RMI

[Sam Newman]

The way I found to stop this, is to grant all permissions to everything -
that is, copy the policy for the tomcat codebase, just remove all mention of
the code base (e.g. line starts grant { rather than grant codebase { ). I.m
trying to track donw exactly what the problem is, but so far it looks like
tomcat isn't properly handling permisisons for specific codebases.

Subject: AT&T Cable Modem Problem Resolved


2 days ago I asked y'all if tomcat could be causing a problem with AT&T
Cable Modem.

I ended up throwing caution to the and listening to my internal voice.

First, I restored WinMe system to a point in time before problems began
(Nifty System Tool).

Modem connectivity began to show great promise after that, but Network
settings were not entirely correct.

Then, the Network configuration tweaking began. Bottom line rule, ignore
AT&T Phone Tech recommend (they're reading off the same sheet of paper that
they give to all of them). Here is what I recommend.

Protect yourself - Two things: 1) Ask field tech to record your assigned IP
address, Sub-net IP Address, Host, Domain Name, Gateway, DNS Server Search
Order. 2) After they install and get things running, go to your Network
configuration and record what they did to get things to run (so you can
recover later, should the need arise without relying on the Corporate Line).

After my final tweaking, I deligently recorded Network settings.  They were
not what AT&T said they should be to work.

I have not tried reinstalling and running tomcat again since - perhaps
tonight. One victory at a time!

The reason I'm documenting to tomcat mail site is this problem may have
occured after installing and starting tomcat, like it did to me. Modem
operation problem may not be related, but should it happen to you, you'll
greatly appreciate what I've docmented here vs. late night, against the
wall, head beatings accompanied by a Phone Tech telling you "everything
should work now" and rebooting 'til tomorrow).

Here we go:

Identification tab:

Host:  XNNN-X (whatever they documented your hostname to be)

Work group: @home

Computer Name:  (LEAVE BLANK)


Network tab:

NIC or USB Card Properties:

X TCP/IP (make sure it's mapped to TCP/IP)

TCP/IP Protocol Properties:

IP Address:

You can go 2 directions:

* Obtain automatically

Or the more radical

* Specify an IP address

RE: Relative Pathing and SSL

[Nibler Jeff R. (PDX1JRN)]

Thanks for your reply Stefan!  I'm using Tomcat 3.2.  It looks as though I
haven't configured SSL with Tomcat correctly.  I wouldn't think that I'd
have to since I'm using IIS to serve everything.  Where would I put that
"secure" tag in my xml file.  Currently, the https connector is remarked out
since nothing connects directly to Tomcat.  I don't have much experience
with this though.  Do you or anyone else know if you must set up the SSL
with Tomcat if you are using isapi?  Thanks again!

Hello all, I'm having an interesting problem persisting an SSL
connection
with my Java servlets.  I am using Windows NT/IIS with Tomcat acting
only as
the servlet container (with the isapi_redirect.dll).  Everything works
fine
except when I need to re-direct a user from the servlet back to any
other
page.  When that happens, for some reason it sets the url to http
instead of
https and then adds a colon with port 443 following the url (which is
obviously the port that it should be on, only automatically using the
https
prefix).  

Example:
Should be: https://www.myserver.com/Test.htm
Instead it gives: http:www.myserver.com:443/Test.htm

I have no idea why this is happening.  I can't find any methods for the
HttpServletResponse object that allows me to set the communication
protocol
etc etc.  Here is the line of code that I'm using:
response.sendRedirect("../../Test.htm");
Notice I am using a relative path.  If I use this instead.
response.sendRedirect("https://www.myserver.com/Test.htm");
then it works.  I hate to hard code the url like that though because I
have
a development server and a production server.  I'm at a loss.  Anyone?

getCookies bug?

[Miles Poindexter]

Hi, newbie to the list here.
I was running Tomcat 3.2.1 on Mac OS X beta and I started having two weird bugs:

1. Tomcat would hang on the first 3 to 6 requests and then finally start working. Then 
everything would work fine.
2. A few times, before it would cease to hang, I would get an error from the Hotspot 
java machine. A fatal error about bad memory space, etc.

This same collection of servlets that make up my site work fine on ServletExec, which 
we are trying to replace with Tomcat.

So I switched to the new Tomcat 4.0 b1 and am having difficulty getting it functional.
At first I had to change the shell script to add my CLASSPATH to it's own. 3.2.1 did 
this, I wonder why it was disabled on 4.0?
Then I had to set both the TOMCAT_HOME and JAVA_HOME which 3.2.1 used to correctly 
guess on its own.
OS X puts the java tools binaries in a folder called "Commands" so I had to create an 
alias called "bin" that pointed to that.

Now it is running, but I get a ClassCastException from catalina when my servlet asks 
the request objects for the cookies. Is this a bug?

Also, how to I make alias to servlets? I did this in web.xml with 3.2.1 but this fails 
with 4.0. I want to make a URI like: /hello  point to a servlet.

Thanks for the help!

OK.  So that's what it does... funny... never knew that...  Figures, I

At least it's not doing it for me.  If I set a servlet in a welcome file
list then nada... and none of the tricks that I've heard of works (doing
a url mapping for something to the servlet and then putting that
something in the welcome file list and so on...).  Also... and this is
an even bigger problem than the last one... the  tag is not
working at all for me.

This is what I have in the 'web.xml':
...

404.htm


404
404.htm

...

The 404.htm is being displayed as a welcome file but every time I try to
access something that does not exist on the server I get the regular
ugly windows internet explorer 404 page.  Have any problems been
reported with ?

RE: Assigning Servlets to different ports.

[William Wishon]

Here's the problem I keep running up against.

The top level XML element is a Server, it contains a ContextManager.The
ContextManager contains both the Connector, which defines the port to listen
on, and the Context entries at the same level.  How do I associate
particular contexts with particular Connectors?  Right now I seem only able
to have one servlet context that maps to "/".  I really should be able to
have two servlets that map to "/", one "/" for port 8080 and one "/" for
port 8081.

I also want the default servlet mappings turned off so that I am no longer
able to access the servlets as "/webapp_name/" when tomcat starts and finds
a war file named "webapp_name".  I only want Tomcat to serve the servlets
that I setup explicitly in server.xml.

One way of achieving this in an apache world would be:

NameVirtualHost 10.0.0.1:8080
NameVirtualHost 10.0.0.1:8081


ServerName port8080.domain.com
DocumentRoot /home/httpd/port8080




ServerName port8081.domain.com
DocumentRoot /home/httpd/port8081




That gives me a different document root for each port.  What I want from
Tomcat is a different servlet to handle requests on each port.

Connection pooling with PostgreSQL

[Aaron Brashears]

After reading and responding to a recent post about postgres, it
dawned on me that postgresql should the support jdbc2.0 calling
mechanisms which include connection pooling. In an effort to find out
how to set it up, and use it with Tomcat 4.0b1, I downloaded the
source code to the jdbc2 driver for postgresql 7.0.3.

I searched through the souce code, but only found references to pooled
connections in the XA classes and not a javax.sql.PooledConnection
implementation. This leads to a few questions:

* Has anyone used pooled connections with postgresql 7? How did you call it?

* Has anyone set up postgresql to work in harmony with tomcat through
jndi? How did you accomplish it?

Thanks.

RE: Client Certificate Authentication

[Stefán F. Stefánsson]

It's not in web.xml.  You have to edit your  tag in
'server.xml'.  Do you have one way authentication working (having the
server authenticate himself for a client browser connecting in)?  If you
have you should have a  tag that looks a little like this:







what you need to do is add the  inside that connector tag.  This should make Tomcat request a
certificate from clients connecting.

note.  This option only works in Tomcat 3.2 and later.

How (and if) you can protect specific webapps with this kind of (two-way
authentication) ssl and have other webapps open on regular SSL (or even
just regular HTTP) is another matter and I'm afraid I can't help you
with that.  Well one thing you could do of course is have two (or three)
instances of tomcat running.  One with two-way authentication, one with
regular SSL and one with regular http.  Then you could set the webapps
in each one according to your needs... but now I'm babbling on and I
don't even know if this is at all what you need...

with my Java servlets.  I am using Windows NT/IIS with Tomcat acting only as
the servlet container (with the isapi_redirect.dll).  Everything works fine
except when I need to re-direct a user from the servlet back to any other
page.  When that happens, for some reason it sets the url to http instead of
https and then adds a colon with port 443 following the url (which is
obviously the port that it should be on, only automatically using the https
prefix).  

Example:
Should be: https://www.myserver.com/Test.htm
Instead it gives: http:www.myserver.com:443/Test.htm

I have no idea why this is happening.  I can't find any methods for the
HttpServletResponse object that allows me to set the communication protocol
etc etc.  Here is the line of code that I'm using:
response.sendRedirect("../../Test.htm");
Notice I am using a relative path.  If I use this instead.
response.sendRedirect("https://www.myserver.com/Test.htm");
then it works.  I hate to hard code the url like that though because I have
a development server and a production server.  I'm at a loss.  Anyone?

Re: Form based auth

[Mike Slinn]

Message-ID: <[EMAIL PROTECTED]>

I read in org.apache.tomcat.request.JDBCRealm.java that the proper URI
should be "/j_security_check", and that if the preceeding "/" is not
present, or if another path is prepended, the path is normalized to
"/j_security_check".

If this URI is recognized, and the path requires security handling,
JDBCRealm.java then prepares a SQL statement to query the database, using
the information specified in the JDBC  in server.xml.

Now, if only I could get it to trigger...

Form based security was not supported in Tomcat 3.1, but is supported in 3.2
and 4.0.

Note that you do ***not*** provide a "j_security_check" class.  That URI is
handled by Tomcat.  The only thing your webapp includes related to security
is
a form login page and a form error page.

See the "examples" application included with Tomcat.  It uses form-based
security to protect the following URL:

http://localhost:8080/examples/jsp/security/protected

I've used the following in the past, where s is a ServletConfig object

ServletContext sc = s.getServletContext();
String fullPath = sc.getRealPath("") + "WEB-INF/myfiles/xyz.dat"

1) i hear people say, to add jar file to $TOMCAT_HOME/lib, I tried that
and that did not work, so i added them to $TOMCAT_HOME/server and that did
work.

2) request or session attributes inside the authenticator??
   I'm using MyRealm, the interface to that is just
   authenticate( String user, String pass ), how can I access the request
   or session that is being authenticated??

RE: Tomcat's class loader

[Randy Layman]

It is the expected behavior because the class loader for
TOMCAT_HOME/lib can't know which context you are trying to load from.  You
really need to put your utility class into each webapp's class path
(WEB-INF\classes or WEB-INF\lib) if you want it to access the classpath for
a particular webapp.

Subject: Tomcat's class loader 


Hi, all, 
I have a servlet, ServletFoo, that calls a utility 
class that lives in a jar file under $TOMCAT_HOME/lib. 
This utility class calls the ResourceBundle.getBundle() 
on a resource bundle that lives in the servlet's home 
(i.e: $TOMCAT_HOME/webapps/SomeContext/WEB-INF/). 
What I found out was that ServletFoo was loaded by 
Tomcat's AdaptiveClassLoader. The utility class 
was loaded by the system's default class loader. 
And of course, that utility class called 
ResourceBundle.getBundle() it couldn't find the 
resouce file because it lived in the servlet's 
home and the system's default class loader doesn't 
have CLASSPATH pointing to that directory. 
I have been able to fix this by passing the servlet's 
class loader to the utility class, so that it passes 
it to the ResourceBundle.getBundle(). 
My question is, is this the expected behavior of 
Tomcat's class loader? Or is this a bug? 
thanks, 
shinta

Re: memory and/or ms problem

[Match Grun]

So what is the tip from Randy?

I also have a possible suggestion, which may be of help:

If you are using JDBC, you should always ensure that you close the
connection to the database. Database connections typically consume
a lot of resource (Oracle uses a process per connection, I am not
sure about MySql or Postgres). Maybe it is the database connection
which is stealing all the memory? Your logic should look like:

try {
  // Get connection
  // Create statement
  // Execute statement
}
catch( Exceptions here ) {
  // Process exceptions
}
finally {
  // Release the connection
}

Also, I make use of a connection pool to share database connections
among multiple modules within the application.

Match.

In Tomcat 3.2, the tomcat-users.xml file is indeed global.  To administer
users for each web app, you need 4.0.

Tomcat stand-alone does not support load balancing as you are describing
it.  However, if you declare your web application to be  in
the web.xml file, and your servlet container supports it (which Tomcat does
not), you can indeed have a load balanced environment.  However, there are
two key issues:

* Your application must ensure that all servlet attributes that you
  store implement java.io.Serializable so that the container can
  move your session to a different machine if it wants to.

* Your container must obey the requirement in the servlet spec that,
  at any given point in time, all requests for the same session are being
  handled by the same JVM.  In other words, containers that support
  session migration can only do so "between" requests.

Not with Tomcat standalone.

Apache JServ (and Tomcat running behind Apache) solve this as follows:

* Requests that are not part of a session can be forwarded
  to any available container instance.

* Once a session is established, all future requests for that
  session will come back to the *same* container instance.

This is accomplished by modifying the session identifier to include a
reference to the originating host, which will therefore be included on
subsequent requests.

Re: PostgreSQL

[Aaron Brashears]

I've had a great experience in general using postgresql 7. The jdbc
driver that comes with it can be compiled for either jdbc1 or jdbc2
depending on your needs. I've never had an issue with the driver, but
I haven't tried using the javax.sql interfaces yet.

The only thing you should be aware of is that postgresql.jar needs to
be in your classpath when starting tomcat.

Different class loader would not matter if it's a parent of the webapp class
loader, but (as we will see) that is not the case.

In that case, you're not going to be able to do this cast.  The classes placed
in $TOMCAT_HOME/server are loaded by a class loader that is not visible to web
applications (i.e. it is not a parent class loader to the one used for your
web app).

If you have additional information from the MyUserPrincipal class that your
application needs to see, I suggest that you store them as request attributes
or session attributes inside the authenticator.  This will work for anything
that is a String or a Java primitive type (wrapped in the corresponding
wrapper class such as java.lang.Integer for an "int").

ADMIN: Anybody out there?

[Caprio, Mike]

Hi,

I'd really like to unsubscribe from the tomcat-user list now.

The mailing list manager is ignoring me, I'm not even getting
a "confirm by replying to this message" message.  I've mailed
the owner address and gotten no replies... could somebody please
either fix the mailing list manager or take me off the list 
manually?  Pretty please?

Until you switch to a servlet container that ignores the CLASSPATH

If you want your application to be portable, you really really really
should do what the specification requires.

Yes.  It was also true for JSP 1.0, so it looks like JRun implemented this wrong
if it behaves the way you describe.

The path you give to  or  is supposed to be the
context-relative path of the file you want to forward to or include.  So, for your
case above, it should be:

Nope ... Tomcat is already doing the "right" thing by the specs.  To see for

That is a correct inference.  You cannot do a  or 
across web applications.

The rationale behind all of this is:
* Web apps are supposed to be independent
* Your system administrator should be able to deploy your
  web app on any context path, and it should still work

(c).  It doesn't create another thread, but it does a synchronized call to the

IMHO using SingleThreadModel is a very bad idea, because it leads you to believe that
you do not have to worry about any threading issues, but that is not true.

It is entirely legal for req.getSession(false) to return null if the original

Keith,

You are more than welcome to include Tomcat in your product, as long as you
obey the conditions of the license agreement.  See the file "LICENSE" in the
top-level directory of your Tomcat distribution.

Basically, it boils down to things like you cannot call your product Apache or
Tomcat, you have to leave the copyright notices alone, and you need to give
credit to Apache for the use of Tomcat in your documentation.  But see the
license for the precise details.

99.9% of the time, this is caused by having a method like this in your servlet:

public void init(ServletConfig config) throws ServletException {
...
}

but forgetting to call super.init(config) inside.  The easiest way to avoid
this is to convert your servlet to the no-args version of init() instead.

The manager app does not have an HTML based user interface -- it accepts individual 
commands as part of the request uri.  For example, to cause a webapp at context path 
"/myapp" to be reloaded, you would request:

http://localhost:8080/manager/reload?path=/myapp

The details of what commands are accepted are in the Javadoc comments for the servlet 
class (org.apache.catalina.servlets.ManagerServlet).

Form based security was not supported in Tomcat 3.1, but is supported in 3.2
and 4.0.

Note that you do ***not*** provide a "j_security_check" class.  That URI is
handled by Tomcat.  The only thing your webapp includes related to security is
a form login page and a form error page.

See the "examples" application included with Tomcat.  It uses form-based
security to protect the following URL:

http://localhost:8080/examples/jsp/security/protected

That happens because the page developer included  tags in the pages
themselves -- it has nothing to do with the  element in web.xml, which
is there for GUI based deployment tools (which Tomcat does not have).

The 2.2 spec is not clear that this is supposed to work (although I agree
with you that it should).  If Tomcat 3.x does not do this, you could submit
a feature request to make it so.

The 2.3 spec will make it mandatory that servlet URIs can be used in
, and Tomcat 4.0 does this correctly.

Are you expecting something to be done with your  element?  If so, you

By "this behavior", do you mean turning off directory listings?  Go to the
"conf/web.xml" file, and look for the  element for the "default"
servlet.  You will see an initialization parameter named "listings".  Change
the value from "true" to "false".

Tomcat's class loader

[Shinta Tjio]

Title: Tomcat's class loader 





Hi, all,
I have a servlet, ServletFoo, that calls a utility
class that lives in a jar file under $TOMCAT_HOME/lib.
This utility class calls the ResourceBundle.getBundle() 
on a resource bundle that lives in the servlet's home 
(i.e: $TOMCAT_HOME/webapps/SomeContext/WEB-INF/).


What I found out was that ServletFoo was loaded by
Tomcat's AdaptiveClassLoader. The utility class
was loaded by the system's default class loader.
And of course, that utility class called 
ResourceBundle.getBundle() it couldn't find the
resouce file because it lived in the servlet's
home and the system's default class loader doesn't
have CLASSPATH pointing to that directory.


I have been able to fix this by passing the servlet's
class loader to the utility class, so that it passes
it to the ResourceBundle.getBundle().


My question is, is this the expected behavior of
Tomcat's class loader? Or is this a bug?


thanks,
shinta

AT&T Cable Modem Problem Resolved

[Dave Parkin]

2 days ago I asked y'all if tomcat could be causing a problem with AT&T
Cable Modem. 

I ended up throwing caution to the and listening to my internal voice.

First, I restored WinMe system to a point in time before problems began
(Nifty System Tool).

Modem connectivity began to show great promise after that, but Network
settings were not entirely correct.

Then, the Network configuration tweaking began. Bottom line rule, ignore
AT&T Phone Tech recommend (they're reading off the same sheet of paper that
they give to all of them). Here is what I recommend. 

Protect yourself - Two things: 1) Ask field tech to record your assigned IP
address, Sub-net IP Address, Host, Domain Name, Gateway, DNS Server Search
Order. 2) After they install and get things running, go to your Network
configuration and record what they did to get things to run (so you can
recover later, should the need arise without relying on the Corporate Line).

After my final tweaking, I deligently recorded Network settings.  They were
not what AT&T said they should be to work.  

I have not tried reinstalling and running tomcat again since - perhaps
tonight. One victory at a time!

The reason I'm documenting to tomcat mail site is this problem may have
occured after installing and starting tomcat, like it did to me. Modem
operation problem may not be related, but should it happen to you, you'll
greatly appreciate what I've docmented here vs. late night, against the
wall, head beatings accompanied by a Phone Tech telling you "everything
should work now" and rebooting 'til tomorrow).

Here we go:

Identification tab:

Host:  XNNN-X (whatever they documented your hostname to be)

Work group: @home

Computer Name:  (LEAVE BLANK)


Network tab:

NIC or USB Card Properties:

X TCP/IP (make sure it's mapped to TCP/IP)

TCP/IP Protocol Properties:

IP Address:

You can go 2 directions:

* Obtain automatically

Or the more radical

* Specify an IP address
(A "nice" Phone Service Tech will give you if you insist that that's
how field tech got it going.  A "not nice" Phone Service Tech will not give
you this info. - politely find an excuse to call again later - like "my wife
is calling me to dinner, gotta go, I'll tweak a little on my own and call
you back")


WINS Config:

* Disable


Gateway:

Installed gateways:

IP Address: NNN.NNN.NNN.NNN
Subnet Mask: 255.255.255.128
(Service Tech will give you IP Address if you insist that that's how
tech got it going, or "let's give it a try to see if that's the problem")


DNS Config:

* Enable DNS

Host: XNNN-XDomain: cityabbrN.ST.home.com

DNS Servier Search Order:

NNN.NNN.NNN.NNN
NNN.NNN.NNN.NNN 
(Service Tech will give you if you insist that that's how tech got
it going)


Bindings:

X Client for MS Networks (choose this option)

NetBIOS:




Restart your machine and enjoy the high speed world of a AT&T Cable Modem!

Re[3]: memory and/or ms problem

[Gerd Trautner]

hi randy, thanks for your tips!

i think i found the reason for the growing memory consumption of my
servlets.

preconditions:
i use servlets to get data out and in a mysql database and generate
html pages with PrintWriter.print(...) statements.
my servlets often use:
...
Statement Stmt = C.createStatement();
ResultSet RS = Stmt.executeQuery("SELECT ..,..,.. from ..");
while (RS.next())
{
   //do something with data
   out.println();
}
...

on each request an instance of a servlet is created and the servlet
starts reading data out of the database and writes it in the
PrintWriter stream.
But what happens if the PrintWriter has no target (because the user
sends another request or more then one other requests)? I am not sure,
but it seems that the servlet tries to write to the PrintWriter stream
and has no success. the result is a growing amount of instances of a
servlet which try to write to a PrintWriter and have no success. and
it seems they keep try writing (and consuming memory) a long time ...

my solution is to check the error state of a Printwriter before
writing in it. so the code from above looks like this:
...
Statement Stmt = C.createStatement();
ResultSet RS = Stmt.executeQuery("SELECT ..,..,.. from ..");
while (RS.next())
{
   if (out.checkError()) break;
   //do something with data
   out.println();
}
...

for my application it seems to work, but i think there must be a better
way,
(why does the write statement throws an exception and the print
statement not?)
any ideas?

I apologize if this is the wrong forum, but I really need a quick solution.

I have a jsp page with an error associated with it. How do I set it up so
that the error.jsp emails me with the error message?

JDBC Realm not triggering

[Mike Slinn]

I feel like I sailed off the edge of the known universe, because there isn't
much documentation for form-based authentication using JDBC realms (at
least, none that I could find, beyond the short JDBCRealm.howto included in
the TomCat docs).

I am using Windows NT Server 4sp6 with JDK1.3 and Tomcat 3.2.1.

I made the following changes to server.xml:




The database tables exist, exactly as shown in , since
mySql is case-sensitive w.r.t. table names.

Here is a piece of my web.xml:

  

  developer
  /pwAdmin/*
  /pwModerator/*
  /pwNormal/*
  /pwPortal/*
  /pwTest/*
  get
  post



  developer



  NONE

  

  
FORM
JDBC

  /index.html
  /register.jsp

  

  
developer
  


Here is the authentication form:

   Login id: 
   Password: 
 



When I press the submit button, I get the following error:
HTTP 404 - File not found
The url reported is http://localhost:8080/j_security_check

Somehow the form action is not being picked up by the TomCat security
mechanism.  What have I missed?

A few more questions:
 - If I omit , does it default to NONE?
 - Is it possible to use * for  to specify that all HTTP
methods are to be subject to security?
 - I would like to use a numeric column in the database to store the user
authentication level, rather than a text string.  Can the JDBC realm be set
up to work this way?
 - I found very little documentation regarding form-based authentication
using JDBC realms. Can you point me to some more?

... thanks
Mike

I've used the following in the past, where s is a ServletConfig object

ServletContext sc = s.getServletContext();

Hey guys,

Using Apache 1.3.19 and Tomcat 3.3m1

Anyone know why I tomcat wouldn't write mod_jk.conf-auto on its startup to
/TOMCAT_HOME/conf/jk ??

Can't get Apache to start cause I don't have any file to point the apache

Hi

We have a working application under Tomcat 3.2.
To call our main jsp, we have to call the full URL:
www.abcd.com/app/index.jsp

If we try:
www.abcd.com/app

We've got an error from Tomcat:
2001-03-02 09:31:03 - Ctx(  ): 404 R(  + //app/index.jsp + null) JSP
file not found
What is this double / ?? Where does it come from??

I think my web.xml file is ok:



index.jsp


index.html


index.htm



web.xml IS in my WEB-INF directory.

And my context too (in server.xml):


What is wrong?

And if I delete my file index.jsp from my directory, and try the URL
www.abcd.com/app, Tomcat return me the list of the file in my docBase
context directory as it shouldWeird!

RE: Tomcat setup

[Darrell Porter]

What OS are you running?

I'll presume Windows 95/98.

The simplest way to fix the "Out of Environment Space" is is to modify
C:\CONFIG.SYS and add or modify the existing SHELL= line to read as such:

SHELL=C:\WINDOWS\COMMAND.COM /P /E:3072

The /P tells COMMAND.COM to Persist after loading and the /E: tells
COMMAND.COM to provide an environment space of  bytes where  is a
decimal number.

If your CONFIG.SYS has a [common] section, you'll want to place the SHELL=
statement on the line  below the [common] heading.

Hope this helps,

Jasper / JSPC config question

[Alan Vogt]

Title: Jasper / JSPC config question






Hi all:


I've got Tomcat 4.0 loaded up.  All the servlet stuff works beautifully.


But I haven't been able to compile any JSP's.  I get "class not found" errors for 
routine classes such as java.security.PrivilegedAction...


I can move these "missing" classes into a new Jar file closer to Jasper...  They then 
get found, but I get unsatisfiedLinkError...


This looks and feels like a config error  Does anyone have a good writeup of how 
to configure Jasper?   Are there any links?  


I didn't see any FAQ's that would help.


Thanks,


Alan

RE: Session beans and multiple tomcat servers ?

[Andrew Gilbert]

One option is a load balancer that will handle session affinity, either on
it's own or through a custom cookie/url rewrite. This is a problem with
almost all web application server solutions, certainly not unique to
Tomcat/JSP.

Subject: Session beans and multiple tomcat servers ?




Hi Everybody,

I have a question about the architecture of tomcat and the sharing of
beans (typically accessed by JSP page code) with a scope of "session".

It seems to me that one major problem with JSP and session-scoped beans
on tomcat (and possibly other servlet engines ? i'm not trying to bag
tomcat specifically here !) is that I am restricted to a hardware
architecture of a *single webserver* running tomcat.

If I wish to run a 'load-balanced' (dns round robin most likely) server
configuration with multiple instances of tomcat sitting behind the same
URL, is there any known way in which to share session-scope java beans
created by one tomcat server across the other servers ?

The only way I can see to solve this problem is to push all session
information to a backend database accessible by all the webservers, and
to look up the session information from the database *each* time the
user moves from page to page (and potentially across tomcat servers).
This seems kludgy, and the database access requirements defeat both the
simplicity of the session-bean approach, and add overhead to the very
scalability and performance that you're trying to achieve by using
multiple servers.

Any guidance or relevent experiences much appreciated ...

Thanks in advance.

Re: Servlet Directory

[Match Grun]

I do this all the time. I assume that the /Work/MyServlets/bin contains
a WEB-INF directory. docBase should be set to the directory which
contains the WEB-INF directory. Tomcat looks in the WEB-INF/classes
directory for any class files.

Adding a context path in server.xml is just one part to it (BTW, in docBase
you
might want to use a fully qualified path rather than a relative path).

The 2nd file that you need to edit is uriworkermap.properties file, and add
(in
your case)
/myservlets/*=ajp12

You may need to restart both Tomcat and the web server.
Good luck.
Anuj.

Hi :-)  with jakarta-tomcat-4.0-b1(standalone, JDK1.3, winnt40),
I find:

*  in webapps/myapp/WEB_INF/web.xml:
-  if I define the following servlet definitions:
   sn_0
   sn_1
   ...
  sn_m

 - and I define the following servlet-mapping:
   
  sn_0
  /up_0
   
   
  sn_1
  /up_1
   
   ...
   
  sn_m
  /up_m
   
   i.e., I map sn_j to up_j  (0<=j<=m)

*  then :
- if  NOONE "from up_0 to up_m" = "/", we can use the
   following to invoke MyServlet:
   http://localhost:8080/myapp/servlet/MyServlet
   and:
   http://localhost:8080/myapp/up_0
   ...
   http://localhost:8080/myapp/up_m
   i.e., now we have m+1 "named" servlet definitions and
   1 "default(non-named)" servlet definition.

- if ANYONE "from up_0 to up_m" = "/", now I find perhaps
   it is what you need (i suppose up_i="/", 0<=i<=m):
  % we still can use the  following to invoke MyServlet:
   http://localhost:8080/myapp/servlet/MyServlet
   and:
   http://localhost:8080/myapp/up_x(0<=x<=m, x ! = i)
   http://localhost:8080/myapp/YYY
   (YYY!=up_x, YYY can be anything :-)   )
   i.e., we can use:
   http://localhost:8080/myapp
   http://localhost:8080/myapp/
   http://localhost:8080/myapp/hahahahaha//hahahahaha :-)
   ...
   and thay ALL invoke the Same servlet defnition whose name

Re[3]: memory and/or ms problem

[Gerd Trautner]

hi all,

i found the reason for the growing memory consumption of my servlets.

preconditions:
i use servlets to get data out and in a mysql database and generate
html pages with PrintWriter.print(...) statements.
my servlets often use:
...
Statement Stmt = C.createStatement();
ResultSet RS = Stmt.executeQuery("SELECT ..,..,.. from ..");
while (RS.next())
{
   //do something with data
   out.println();
}
...

each request an instance of a servlet is created and the servlet
starts reading data out of the database and writes it in the
PrintWriter stream.
But what happens if the PrintWriter has no target (because the user
sends another request or more then one other requests)? I am not sure,
but it seems that the servlet tries to write to the PrintWriter stream
and has no success. the result is a growing amount of instances of a
servlet which try to write to a PrintWriter and have no success. and
it seems they keep try writing (and consuming memory) a long time ...

my solution is to check the error state of a Printwriter before
writing in it. so the code from above looks like this:
...
Statement Stmt = C.createStatement();
ResultSet RS = Stmt.executeQuery("SELECT ..,..,.. from ..");
while (RS.next())
{
   if (out.checkError()) break;
   //do something with data
   out.println();
}
...

for my application it seems to work, but i think there must be a better
way,
(why does the write statement throws an exception and the print
statement not?)
any ideas?

The servlet idea is the best I think.  I believe you could also write
your own class that is Runnable that creates a Thread for your RMI
process and one for the org.apache.tomcat.startup.Tomcat class passing
any command-line params to this class.

I'm receiving an error that I can't understand.

The console displays this error :
org.apache.jasper.JasperException: Unable to rename class file --firstPath-- to 
--secondPath--
 
The page I'm tryng to view is being correctly compiled and it's showed in the 'JSP 
Page Compile Generated Code' (a Visual Age folder) without an error.

I've searched for the file indicated in the --firstPath-- and for the one indicated in 
the --secondPath-- ( .class files ): neither of them exists.

Thanks in advance.

The form of codebase you are using only works for plain HTML
pages. One easy way to solve this problem and also make image
and sound files work right is to put a  tag in
the  section of the page your JSP writes. Use that
tag to point to the server alias for the directory that
has your class files.

RE: loading applet from web-inf/classes sunfolder

[Randy Layman]

You must move the Applet code out of the web-inf directory.  Tomcat
doesn't allow anything in this directory to be published through the
HTTP/AJP connections (its for security purposes).

So following your conventions, you probably want to create a
directory called /fundopt/applet and put your applet code in there and then
use codebase="../applet/".

hi

my home-directory on the tomcat server looks like this
http://localhost:8080/fundopt. under fundopt i have a folder (called jsp)
containing all my jsp files. 
i want to acces an applet (which has its source files in the
web-inf/classes/xy folder) with the following piece of code:
from jsp file (in http://localhost:8080/fundopt/jsp/appletCaller.jsp)
. this however doesn't work. 

how can i address the applet? what codebase am i to choose?

any help is appreciated
