mySQL again

[Herchel Wojciech]

Hi!
My connectionURL in server.xml now looks like this:
"jdbc:mysql://localhost/auth?user=rootpassword=somepassword"

and tomcat doesn't start up (although there is no error msg or anything) and
when i execute tomcat stop i get the following exception:
org.xml.sax.SAXParseException: Next character must be ";" terminating
reference to entity "password" and a stack trace follows...

why is that?

RE: log4j usage in tomcat?

[GOMEZ Henri]

Within my classes i'm utilizing Log4j logging which requires 
Log4j to be
configured.  I normally configure Log4j within my unit test 
cases, but in the
case of Tomcat, to my pleasant surprise, i found that 
(seemingly) without
configuration, it was handling all my log statements and 
outputing them to the
jvm.stdout file in the logs directory.

Log4j logging is configurable, but i was unable to find the 
location within
Tomcat where they set the Layout pattern.  For that matter, i 
couldn't find
*any* references to Log4j.

Questions:
1. Does Tomcat really use Log4j?
2. Where can i set the layout pattern?

+1

Must be easy to plug log4j in TC 3.3

I guess you should escape the "" character in your connectionURL by replacing it with 
"amp;", as the XML parser will parse entities like "lt;" or "quote;" or things like 
that...

Try

jdbc:mysql://localhost/auth?user=rootamp;password=somepassword

instead, that should work...

Hi,
  You might want to try something like the following. It works for me.

 RequestInterceptor

Life of a class?

[Neil Edney]

Hi,

We have implemented a database connection pool class (extract below) and use
the 'getInstance' method to ensuire that there is only one instance created
at any one time.

What we need to know is when will this class be destroyed? Is it went the
server is stopped (or crashed!) or will it timeout after a period of
non-use?

Regards,
Neil


public class DbPool extends Object implements java.io.Serializable {

private static DbPool instance;

public static DbPool getInstance(){
if (instance == null)
instance = new DbPool();
return instance;
}

/** Creates new dbPool */
private DbPool(){

Crashing tomcat

[Christopher Miller]

I have written a simple servlet to access a database and place the 
results in an html page. However this is regularly crashing the tomcat 
server.

I have tomcat and apache running together with the basic config files, 
but I am not sure where the fault lies (servlet or config file).

the error on tomcat crashing is in the form of

"instruction at xxx referenced memory at xxx. the memory could not be 
written"

Any help would be well received.

Re: Life of a class?

[uthay]

The class which loads the DbPool class should release it. ie. if there is no
reference to this class and the static instance is also no longer
referencing any object, I beleive the class will be ready for gc.

Jserv to Tomcat documentations?

[Paolo Fantoli]

*This message was transferred with a trial version of CommuniGate(tm) Pro*
Hi,
we are trying to install an application that should work with Apache Web
Server and Apache Jserv using IIS and Tomcat.

We had followed the TOMCAT IIS HOWTO and now IIS and Tomcat cooperates.

Our new problems is that we do not know which are the corrispondensces
between Jserv and Tomcat as for the configurations matter.

What we think is that:
jserv.properties corresponds to tomcat.properties
jserv.conf corresponds to tomcat.conf

while for
 ApacheJserv.jar we do not know the corrispondences.

The directory Apache Jserv1 1.1\servlets we don't know what is the
corrispondences.

Now,
Is there an HowTo or some documentations like that explaining easly
how to migrate from Jserv to Tomcat?

Regards,

Paolo

AW: Crashing tomcat

[Ralph Einfeldt]

Give a bit more info of your environment.
(OS, Apache version, Tomcat version, which connector mod_jserv or mod_jk)
In which file is the error reported ? Is there more information available 
in the log ? (With the informations you provided it's just guesswork,
to decide if that's an error of apache, the connector, tomcat or some thing
outside.


It may be an error in your JVM or a native library.

- Look if there is a newer version for your jdk
- If not (or if it doesn't change anything)
  try the JDK of a different vendor.

RE: Crashing tomcat

[Stefán F. Stefánsson]

Hello..

Are you guys running windows?  If so, are you getting the popup window
with the red cross and an ok button saying that some memory address
can't be read?

If that is the case I would bet that you have found a bug in the JVM.
The reason for that being that Java doesn't have any pointers so there
is no way that any of your code could generate this message.  Java would
not allow you to write into an illegal memory address, this window would
only appear if the JVM was doing something like that (or perhaps the
JDBD driver, depending on what type of driver you are using).

Are you guys using any native code (dll's or system calls)?  What type
of JDBC driver are you using (Type 4 is pure java and should therefore
not be able to cause this behavior but Type 1 (and maybe Type 2 too) may
rely on native code and could therefore cause the error message to
occur.

Hope this gives you guys a hint,
Regards, Stefan.

memory and/or ms problem

[Gerd Trautner]

Hi tomcat-users,

I am having some memory related troubles with my servlets running on
tomcat 3.2.1 on an win nt 4 workstation machine.
I read all previous messages in the list with the term "memory" in it,
but everything i try does not help.

problem: the memory consumption of the java.exe increases slightly, the
over all memory consumption of the system increases fast and memory is
not released. after a week (and about 400 hits or so) the server runs
out of memory (tomcat gives a OutOfMemoryError and quits).

what i did:
- set java max heap size (nothing changed)
- set max_threads (30), max_spare_threads(20) and min_spare_threads(5)
  for both http and https ConnectionHandler
- set session-timeout to 1 Minute
- added System.gc() to end of every servlet

my application uses servlets and mysql, i close every mysql connection
and i am not able to find anything i could change to get the memory
freed.

I also use ms-stresstool and i can simulate this memory-problem.

could anyone give me some assistance please?

thanks,
Gerd

Re: Tomcat class loader

[Chris Haynes]

Uthay,

I still think you've got a basic JAVA coding error - a class mismatch
in a .jsp called something like CampView.jsp


Look carefully at line 103 in the file below in the 'work'
subdirectory,
paying special attention to any assignments or method calls in *your*
code that show up in that line.

_0002fjsp_0002fPRJsp_0002flobCampView_0002ejsplobCampView_jsp_5.java

The run-time system is finding an instance of PRDashBoard.PRContext
at that point when it is expecting something else.

Only you can tell:
(a) what class your code is actually expecting at that point,
(b) Why a PRDashBoard.PRContext is getting there and where it came
from,
c) Why the class that should there isn't!

 It is to do with a session bean class I have.

Re: Tomcat class loader

[uthay]

 Chris,
Thanks for your help

I use few beans within a page.
And if there is any class cast exceptions during the compilaion of  that jsp
I will get a that specific class cast exception not necessarily the jsp file
class. More over it doesn't happen specific to a jsp page.
As I said, I am only getting this error occasionally.
Every time I change my PRContext bean class the tomcat throws this
exception. And we have to restart it. Some time for nor reason (probably a
configuration error) tomcat holds onto the older version of the bean class.
As you suggested I suspected an application fault at the beginning and
traced the java file. It looks fine.
the line number indicates a problem about page forwarding.

if (true) {
String __url = (String) "lobCountryView.jsp";
// Forward to the above url
out.clear();
pageContext.forward( __url);
return;
   }

I can't spot anything.
If there is an error why work in the first place.

At the moment application seems to work fine. (Since I am not modifying the
bean class)
I intend to get into this more detaily soon.
If you have any thought on this please share it.

Thanks again
Uthay

RE: Tomcat Crashes

[Randy Layman]

Two common causes of crashes, in my experience, are using the
JDBC-ODBC bridge (its not thread safe and when concurrent access occurs it
crashes the JVM).  The other is in the JIT complilation.  I've had a lot
less trouble with the newer JDKs (1.2.2_007) than the older ones (1.2.2_002
and 004).

The solution to the second problem is pretty obvious - upgrade your
JVM or turn off JIT.  The first solution you can either serialize requests
or find new database drivers.

If your problem isn't one of these two things, I would suggest
looking where you are using native code as well as the differences between
the two machines (including usage, it the one with the higher load crashes
more frequently then the problem is probably something you are using isn't
thread safe)

Generating a random alphanumeric string

Re: Tomcat class loader

[uthay]

I think you are right.

 You don't have persistent beans in there which are storing old copies
 of the class you are changing, do you?

I have a session bean which is serialised as bean should be.

 It's possible that a class cast exception is being thrown if a new
 version arrives where an old one is expected, or vice versa - but I'm
 guessing now

On changing its version tomcat throws cast exception

Any body else got a similar problem?

Will it be changed in the future version?




 Uthay,

 I can't see anything either, unless pageContext is changing
 dynamically.

 You don't have persistent beans in there which are storing old copies
 of the class you are changing, do you?

 The reason I don't use RMI or anything based on it is because coping
 with newer versions of a class - even if logicaly the same - seems
 really tricky.

 It's possible that a class cast exception is being thrown if a new
 version arrives where an old one is expected, or vice versa - but I'm
 guessing now.

 Don't think I can be of any further help to you.

 Best of luck!

 Chris

  Chris,
 Thanks for your help

 I use few beans within a page.
 And if there is any class cast exceptions during the compilaion of  that
jsp
 I will get a that specific class cast exception not necessarily the jsp
file
 class. More over it doesn't happen specific to a jsp page.
 As I said, I am only getting this error occasionally.
 Every time I change my PRContext bean class the tomcat throws this
 exception. And we have to restart it. Some time for nor reason (probably a
 configuration error) tomcat holds onto the older version of the bean
class.
 As you suggested I suspected an application fault at the beginning and
 traced the java file. It looks fine.
 the line number indicates a problem about page forwarding.

 if (true) {
 String __url = (String) "lobCountryView.jsp";
 // Forward to the above url
 out.clear();
 pageContext.forward( __url);
 return;
}

 I can't spot anything.
 If there is an error why work in the first place.

 At the moment application seems to work fine. (Since I am not modifying
the
 bean class)
 I intend to get into this more detaily soon.
 If you have any thought on this please share it.

 Thanks again
 Uthay

  Uthay,
 
  I still think you've got a basic JAVA coding error - a class mismatch
  in a .jsp called something like CampView.jsp
 
 
  Look carefully at line 103 in the file below in the 'work'
  subdirectory,
  paying special attention to any assignments or method calls in *your*
  code that show up in that line.
 
  _0002fjsp_0002fPRJsp_0002flobCampView_0002ejsplobCampView_jsp_5.java
 
  The run-time system is finding an instance of PRDashBoard.PRContext
  at that point when it is expecting something else.
 
  Only you can tell:
  (a) what class your code is actually expecting at that point,
  (b) Why a PRDashBoard.PRContext is getting there and where it came
  from,
  c) Why the class that should there isn't!

[TC4] Bug? Authentication problem with HTTP 1.1 client (MSIE)

[Jason Harrop]

Hi

I'm using TC4 built from CVS on 17 Feb, and I'm scratching my head about 
a strange problem when i try and access 2 webapps which have the same 
realm name in their web.xml file, as in:

   login-config
 auth-methodBASIC/auth-method
 realm-namemyRealm/realm-name

If I visit these webapps using a HTTP 1.0 client (eg NS 4.7, or IE 5 or 
5.5 with "Use HTTP 1.1" deselected), i get the expected sequence of a 
401 error, at which point the browser presents the authentication 
dialog; then on subsequent protected pages, the browser responds to the 
401 error with authentication information without involving the users.

If I visit these webapps using either IE 5 or 5.5 in their default HTTP 
1.1 enabled mode, then what happens is this:

For IE 5.5, when i visit the first page, i am asked to authenticate. 
Then, when i visit the second page (on my setup, this is in a second 
webapp, but with the same realm-name), i am presented with a blank 
screen.  The tomcat logs show the 401 response, but they DO NOT show a 
subsequent request in which the authentication information is provided 
by the browser.

HOWEVER, according to my packet sniffer, that request _is_ being sent, 
however Tomcat never responds to it:

  G E  T / T  e s t D  r i  v e  / p  r o  t e  c t  e d / s  h o  w 
H  o m  e D  i r  e c  t o r yH  T T  P /  1 .  1

  A u  t h  o r i z  a t  i o  n :B  a s  i cZ n J  l Z  D p  u 
Z  X J  r

  [Tomcat sends the page]

  . 1

  A u  t h  o r  i z  a t  i o  n :B a s  i cZ  n J  l Z  D p  u 
Z  X J r

Clicking refresh successfully grabs the page for me, without me having 
to type any authentication info again. So i think this might a bug in 
Tomcat 4's HTTP 1.1 connector (since things are okay with a 1.0 client)?

With IE 5, the second time Tomcat sends a 401, IE asks me to 
authenticate, even though the WWW-Authenticate header is the same one it 
has seen before.  This looks to me like a bug in IE 5.

Any thoughts?  BTW, i'm not using the single sign on support valve.

thanks

Jason

 Tomcat does not cache files as such. Your problem must
 come from a different source.

RE: useing beans.

Did you try changing the class to have public access?
This is just a hunch but the default constructor on a
non-public class may not be accessible given the IllegalAccess

You need to put your bean in a package and specify the package
completely in the useBean tag.  Apparently, when Tomcat sees
the kind of usage you show, it assumes that the class is in the
"current" directory.

IIS/PWS fails to load isapi_redirect.dll filter

[Hawkins, Keith (Keith)]

I am trying to get the isapi_redirect.dll filter to run under IIS/PWS.

I have quadruple checked all the values that I need to set up according to
the instructions posted on the Tomcat site.  But every time I stop and start
the web service, I get the dreaded  red down arrow.  (The bane of my
existence these days ;-)

I got the filter set up fine on Windows 2000, but I can't get it going on a
machine running with NT4.0 Service Pack 5.

I have a few questions for those who may have gotten this working correctly
on NT.

1)  If a filter fails to load,  where does IIS/PWS log the problem that is
preventing it from loading??

2)  The instructions say to for PWS I need to add a Filter DLLs key to the
registry.  What is not clear
is whether Filter DLLs is a KEY name with a default value of the full path
to isapi_redirect.dll  or
Filter DLLs is a STRING VALUE entry at the W3SVC/Paramaters level with a
value of the full path to the isapi_redirect.dll. Or do I even need to do
this since I was able to set up a filter entry using the management
console??

Any help would be appreciated.

Thanks,
Keith

Tomcat, Jaxp, Xalan

[Scott Walter]

Help!

I am trying to do xml transformation with tomcat.  I
want to use the xalan transformation engine.  However
the jaxp.jar that is included in the tomcat lib is
getting in the way.  I keep on getting a "Namespace
not supported by parser" exception.

If I remove jaxp.jar and parser.jar from the tomcat
lib directory and replace it with the xerces.jar
everything works great.  Is there anyway to keep the
installed jaxp.jar and parser.jar but still get my
transformations to work, because my app will be
running at a hosting provider and they probably won't
make the change I need.

thanks in advance,
scott.

Below is the code I use to do my transformation:
TransformerFactory tFactory =
TransformerFactory.newInstance();
Transformer transformer =
tFactory.newTransformer(xslSource);
transformer.transform(xmlSource, new
StreamResult(response.getOutputStream()));

Subject: RE: Tomcat Crashes



 Two common causes of crashes, in my experience, are using the
 JDBC-ODBC bridge (its not thread safe and when concurrent access occurs it
 crashes the JVM).  The other is in the JIT complilation.  I've had a lot
 less trouble with the newer JDKs (1.2.2_007) than the older ones
(1.2.2_002
 and 004).

 The solution to the second problem is pretty obvious - upgrade your
 JVM or turn off JIT.  The first solution you can either serialize requests
 or find new database drivers.

 If your problem isn't one of these two things, I would suggest
 looking where you are using native code as well as the differences between
 the two machines (including usage, it the one with the higher load crashes
 more frequently then the problem is probably something you are using isn't
 thread safe)

Too many open files with Tomcat-3.2.1 under Solaris

Hi,

I just want to port our tomcat application to Solaris-2.7 and after a
short time I get the error message "Too many open files" from
java.net.SocketException.

The same applications does not have the problem under Linux.

I'm pretty sure that not our application causes the problem.

I use j2sdk1_3_0_02 under Solaris.

Any ideas?

Re: I CANT COMPILE SERVLETS!!!HELP

[DSailing]

I'm not sure this is what you are asking.  You never said what kind of
error you were getting.  But I though a list of my command line parameters
might help.  here is what I use:

-deprecation -classpath "d:\Program Files\jakarta-tomcat\classes";"\Program
Files\jakarta-tomcat\lib\servlet.jar" -d "d:\Program
Files\jakarta-tomcat\classes" $(FilePath)

1. You can leave "-deprecaton" out.  I just use it for my own reasons.
2.  "d:\Program Files\jakarta-tomcat\classes" is where my servlets go and
it also contains any other personal classes I use.  It appears in both the
"-classpath" and the "-d" parameter.
3.  "\Program Files\jakarta-tomcat\lib\servlet.jar" is provided with
tomcat.  It appears only in the "-classpath" parameter.
4.  "$(FilePath)" is replaced by the file name, which matches the class
name, of my servlet.
5.  Several of the file names are in quotes because they have imbedded
spaces.

I'm not sure this is what you were asking, but in case it was, this is what
I do.

Tomcat mod_jk: jsp pages don't display the first time invoked

[Xu, Lifeng]

Hi all,

I just lately replaced mod_jserv with mod_jk as Tomcat plug in in Apache. It
works ok except one thing: for some of my jsp pages, the first time invoking
them will not get the page displayed. Instead, I get a "page not exist"
error. However, if you go back and hit refresh, then the right page will
display.

This only happens after we switched from mod_jserv to mod_jk. I am sure this
is configuration issue, I just can't pin point the problem.

Can somebody help me on this?

Thank you in advance.

I am also new to mod_jk, but I think if you are running NT, you don't load

I could be wrong though. Like I said, I am new too. So take my advise in
your own risk...:)

Good luck.

MyRealm - cannot instantiate class exception

[DUDGEON]

Although I've been using tomacat for sometime, I'm now needeing to start on
some work to match up the authentication and authorisation within catalina
to our enviroment. To do this I'm putting together a LDAPRealm. I have a
rudimentary LDAPRealm that works fine on its own, but when I put it into
tomcat I'm getting a cannott instantiate class exception from within my
code. Could someone give me a guide into what I'm doing worong. It's
probably pretty basic, but I'm new to this.

What I did:

created a org.apache.catalina.realm.MyRealm class that contains an
authenticate() method that connects to the LDAP server as follows

public Principal  authenticate(String username, String credentials) {
   
MyRealmPrincipal principal = new MyRealmPrincipal(username);
Hashtable env = new Hashtable(11);
env.put(Context.PROVIDER_URL, 
"ldap://localhost:389/dc=britbio,dc=co,dc=uk");
env.put(Context.SECURITY_PRINCIPAL, principal.getDistinguishedName());
env.put(Context.SECURITY_CREDENTIALS, credentials);

try {
  // Create the initial directory context
  DirContext ctx = new InitialDirContext(env);
  // if we get here then we've bound OK

  System.out.println("Authenticated for " +
principal.getDistinguishedName());

  // get the groups from the JNDI context and define them as roles
  getRoles(ctx, principal);

  // unbind
  ctx.close();

  return(principal);


} catch (NamingException e) {
  // could not bind - wrong password?
  System.err.println("Failed to bind to directory for " + username);
  e.printStackTrace();
  return(null);
} 


this code works fine on its own (outside catalina). However when I try to
run it within catalina (jar'd up the clases, put them in
$CATLINA_ROOT/server), my code gets called, but the bind to the LDAP server
fails with the following exception 


Failed to bind to directory for tom

SSL Tomcat

[Brett W. McCoy]

I have some questions regarding the use of mod_ssl with Apache and Tomcat.
The onlie docs don't go into great detail about configuration, so hopefuly
someone here has more clue than I.

In the online docs, the author recommends putting the mod_jk directives
under the SSL port 443 virtual host seciotn in httpd.conf.  In doing this,
though, does this put everything in my configured context under SSL?  If I
only want specific documents using SSL, but have the rest of the URLs on
the server accessible without requiring SSL, should I do my JkMount
directives outside the SSL virtual host section, and just use directory by
directory or file-based directives inside the SSL section?  Is it possible
to use .htaccess files with the SSL directives for JSP files?

Thanks in advance for any help...

SSL Tomcat, continued

[Brett W. McCoy]

I forgot one more question, that is more of a programming question than a
configuration question.  I need to be able to use a custom error page that
gets served if SSL is not available.  Can this be accomplished with a JSP
file, by capturing the error and redirecting to the error page in a
manner analogous to redirecting to a custom 404 page?

You'd have to have a redirection in your ASP page to the new JSP file.

RE: IIS 5.0 and adding contexts (JSPs not being processed)

[Rodriguez Victor A.]

Hi,

 One interesting thing to note is that the Javascript is still 
 executed (i.e.
 stuff insideSCRIPT language="Javascript"/SCRIPT tags)

Please, note that JSP executes in the server side, and JavaScript in the
client side (a.k.a. browser).

Cheers.

Protecting mysql access (was: re: mySQL again)

[Rob Tanner]

Slightly off topic, but important!

Having seen way too much in terms of hacking and system compromises, 
might I suggest you create another, and far less privileged user than 
root, for accessing mysql.  Unless you've gone into the grant tables 
and creatd a different mysql superuser and reduced root's priv, then 
the root login to mysql is like root on unix, superuser, God, etc.  If 
multiple users have shell access to the tomcat host system, and those 
same users are not authorized as mysql root, than I know of no way to 
keep unauthorized eyes from looking at the server.xml file other than 
by making it sysroot protected. But to do that, you need to run tomcat 
under root.

If anyone has a good mechanism for securing the server's and/or 
servlet's credential for db access, I'd certainly love to hear it. 
That issue has been my one and only thorn in the side since I began 
switching for perl/cgi (where the solution to that issue is a 
no-brainer) to using tomcat.

 I guess you should escape the "" character in your connectionURL by
 replacing it with "amp;", as the XML parser will parse entities like
 "lt;" or "quote;" or things like that...

 Try

 jdbc:mysql://localhost/auth?user=rootamp;password=somepassword

 instead, that should work...

RE: no class def found sun.tools.javac.Main

[Randy Layman]

This comes from Tomcat not being able to find your JavaC compiler
(imagine that, not found class sun.tools.javac.Main).  You need to set your
JAVA_HOME variable so that it points to your JDK root directory.

And read the manual and/or mail list archives and/or the FAQ.

Hello all,

My configuration is as follows:  

WIN2K 
Apache 1.3.14
Tomcat 3.2.1
Poolman 1.4.1

I have include the poolman.jar file in my CLASSPATH as per the
documentation.  I have tested the connection with the PoolManSample.java
program provided and all works fine from outside of tomcat.  I have a
servlet which now attempts to connect to the database via PoolMan, but I
keep getting the following error:

 Could not find 'poolman.props' -- now attempting to read deprecated
file name 'pool.props'... failed.

I have tried placing the poolman.props file in my webapps directory,
TOMCAT_HOME\webapps\myapp and in the classes directory under myapp and in
about every other directory I can think of but to no avail.  Is there
something else I need to configure in the web.xml or in tomcat.conf to have
this work correctly?

Any help with this is appreciated.

Re: Protecting mysql access (was: re: mySQL again)

[Rick Herrick]

On our server, we basically grant NO remote access privileges to ANY users, 
including root.  This means that any access to the database has to be done 
from the localhost.  So instead of doing the two normal grants you might 
do, like this:

GRANT SELECT,INSERT,UPDATE ON *.* TO soandso@localhost IDENTIFIED BY 
'password';
GRANT SELECT,INSERT,UPDATE ON *.* TO soandso@"%" IDENTIFIED BY 'password';

The first allows access from the localhost.  The second allows remote 
access.  Just don't do the second.  Then someone has to hack in and get 
local access to the database somehow and if they can do that, then you've 
got other security problems besides MySql!

At 08:01 AM 3/1/2001 -0800, you wrote:

RE: no class def found sun.tools.javac.Main

[Stefán F. Stefánsson]

Thanks for your answer.

I should have been more clear in my previous post.

Ok... so here's the deal,

I have a server application that integrates Tomcat.  This server starts
tomcat up through use of the EmbeddedTomcat class.  So far so good.
When I start the server from a command line or within JBuilder
everything is just fine and dandy and works oh so well ;o)
However, I'm trying to create an ant buildfile to do everything for me.
I've managed to have the buildfile build everything and create a jar
file and all that but when I try to have it run the server, the server
goes up but the first JSP I try to access gives me that error I was
talking about.

I'm not a newbie to Tomcat so I knew about that JAVA_HOME variable (and
it _is_ set on my computer)... I should have mentioned that in my first
post... sorry about that.

Regards, Stefan.

RE: no class def found sun.tools.javac.Main

[Randy Layman]

If I understand your problems - its that when Ant starts the server
you can't compile your JSPs?  

I think your problem is in your Ant build file not setting the Java
home. How are you trying to invoke Tomcat - script or calling the class?  If
the class, make sure to add tools.jar to the classpath, if by script, make
sure that you set the environment variables, either in the script or
otherwise.

Thanks for your answer.

I should have been more clear in my previous post.

Ok... so here's the deal,

I have a server application that integrates Tomcat.  This server starts
tomcat up through use of the EmbeddedTomcat class.  So far so good.
When I start the server from a command line or within JBuilder
everything is just fine and dandy and works oh so well ;o)
However, I'm trying to create an ant buildfile to do everything for me.
I've managed to have the buildfile build everything and create a jar
file and all that but when I try to have it run the server, the server
goes up but the first JSP I try to access gives me that error I was
talking about.

I'm not a newbie to Tomcat so I knew about that JAVA_HOME variable (and
it _is_ set on my computer)... I should have mentioned that in my first
post... sorry about that.

Regards, Stefan.

This comes from Tomcat not being able to find your JavaC
compiler
(imagine that, not found class sun.tools.javac.Main).  You need to set
your
JAVA_HOME variable so that it points to your JDK root directory.

And read the manual and/or mail list archives and/or the FAQ.

[mikhail malamud]

Here is the setup I have.
Tomcat 3.2.1 with mod_jk
Apache 1.3.17. DocRoot /usr/local/apache/htdocs.

First, I got the existing /examples webapp to work. Apache is calling
tomcat and its all good. But now I am trying to deploy my first tomcat
application and going through hell. My DocRoot looks the following way.

DocRoot/vitamin/WEB-INF/
DocRoot/vitamin/WEB-INF/classes/edu/myschool/util/HelloWorldExample
Vitamin is the top level of an application I am trying to deploy.

I added following  information to the following files.

/Directory

JkMount /vitamin/servlet/* ajp13
JkMount /vitamin/*.jsp ajp13


Location "/vitamin/WEB-INF/"

##
Context path="/vitamin"

RE: Generating a random alphanumeric string

[Craig O'Brien]

This intrigued me so I just wrote this little program.  Of course it could
be wrapped up in a bean and it needs to check against a list of established
passwords but it gives you upper-lower case random sequence of alpha-numeric
characters. Just feed it the length that you want. It even cleans up after
itself. :0)

public class CraigsRandomizer   {

// generates a random alpha-numeric sequence

public static void main(String[] args)  {
CraigsRandomizer t = new CraigsRandomizer();
t.randomPass(12); // set to length of 12
}

final void randomPass(int len)  {
int[] random = new int[len];
int i = 0;
String result = "";

while(i  random.length){
int n = (int)(Math.random() * 122);

if (!(n  49)  (!((n = 58)  (n = 64)))  (!((n = 91) 
 (n =
96  {
random[i] = n;
i++;
}
}
for(int j = 0; j  random.length; j++)  {
result += (char)random[j];
}
random = null;
System.out.println(result);
}
}

Let me know if I can help.

 Temat: Generating a random alphanumeric string


 Hello, can anyone show me an example or give me a clue about how
 to generate a random alphanumeric string of lets say 16-32 chars?
 TomCat is obviously doing it for the session ids, but how would I
 do the same in a servlet?

Well, you should make chages in mod_jk.conf file (which is included in

Then add new connector for apjv13 in server.xml file (look at dokumentation

In your directory

Hello World

and try to get it in the browser:

and do it the same with your apache port, say

Just a WAG, but in servlet-class you spect edu.myschool.util.HelloWorldExample
Is that right?  I haven't packaged any of my classes yet so I haven't tested
that.
Also, have you tried it without Apache?  Just hit :8080  Does that work?

A minor WAG here but would it not be /servlet/HelloWorld since the servlet name
is
HelloWorld (it doesn't matter what your class name is, whatever the servlet name

what Tomcat will refer to it as.)

RE: *** Please help me

[Randy Layman]

It would appear that your Tomcat is not working correctly (looking
at the isapi log it determines it should redirect, however the the service()
method indicates that its failing.

Does Tomcat work on port 8080?  I would guess that the Microsoft JVM
is causing your problems.  Try installing either Sun's JVM or IBM's.

Read my message again... There were more steps there {:-)}...
Read the notes at http://www.ccl.net/cca/software/UNIX/apache/index.shtml 
and http://www.ccl.net/cca/software/UNIX/apache/tomcatfaq.shtml

Primarily check if your web.xml is correct and in correct place, if
your server.xml has an entry:
   !-- Apache AJP13 support. This is also used to shut down tomcat.
  --
Connector className="org.apache.tomcat.service.PoolTcpConnector"
Parameter name="handler" 
   value="org.apache.tomcat.service.connector.Ajp13ConnectionHandler"/
Parameter name="port" value="8006"/
/Connector

and  you have
  Context path="/vitamin" 
docBase="/usr/local/apache/htdocs/vitamin" 
  crossContext="false"
  debug="0" 
  reloadable="true"  
   /Context
there.


And if the port is for ajp13 is the same as in worker.properties file.
Check if your worker.properties are configured correctly for apj13
and if you are including the right file in the httpd.conf

Once you corrected/cheked everything restart kill apache, kill tomcat
start tomcat, start apache.

Reading a file from a Context

[Brett G. Palmer]

What is the best way to read a file from a Context in Tomcat?  I know I can
get the context path from the "getContextPath()" method, but most file
stream APIs require a full path.  There most be a clean way to accomplish
this without hard coding any directory path info.

Any suggestions would be appreciated?

Thanks,

Brett

Startup AND shutdown of separate JVM's

[Scott Tatum]

I have been using Tomcat for a while now and with good success. I
recently setup virtual hosts (named vhosts) and was surprised when it
all worked the first time. =) The documentation in the mod_jk-howto was
a great help.

Here is my setup: I have two different (eventually more) virtual hosts
on one machine being served by Tomcat 3.2.1 and Apache 1.3.14. Right now
there is only one Tomcat JVM running, but I'm getting ready to break
this up into 2 separate JVM's. The configuration part is trivial now
that I have virtual hosts working, but there is one part I can't figure
out.

The two vhost setup is for production and development versions of the
same application. So one JVM I will need to restart regularly, and the
other needs to stay up as much as possible.

There are a couple of problems I forsee that I need to understand and
tackle before moving forward. One is that there is only startup/shutdown
script for Tomcat. I understand that, by creating different server.xml
configuration files and using (e.g.) startup.sh -f server1.xml, I can
start separate servers. My question is, how do I stop them separately?
If I have to write my own scripts I am willing to go that route, I just
want to make sure there's not some preexisting method.

Also I read in the FAQ that if you restart Tomcat, you also have to
restart Apache. I've tested this out with mixed results. Is this true?
If that is the case, running separate JVM's for each website becomes
useless to me. No offense to the other benefits of running separate
JVM's! If I have my production JVM which needs to stay up, but Apache
has to restart every time I restart my development JVM, wouldn't that
mean I have to restart my production JVM every time I restart my
development JVM? Worst case, I can run my development on the built-in
webserver, but it would be nice to use app.domain.com and
app-dev.domain.com without having to tack on a :8080.

So in review, my questions are: If running separate JVM's connected to a
single Apache, how do I restart one JVM while leaving the other running?
Also, if running under said setup, does restarting one Tomcat JVM mean
that Apache and any other Tomcat JVM's have to be restarted as well?
Thanks in advance for any insight.

-Scott
(p.s. was running JRun 3 before Tomcat. Experienced daily lockups. No
lockups with Tomcat and it is noticeably faster. JRun 3 has a nice
web-based admin setup though.)

ajp13 connector is set up properly because default app works fine with
it and so do my jsp's.
As you recommended, I decided to get simple things to get to work first.
So, I tried to execute a servlet not in
/WEB-INF/classes/edu/myschoo/util/HelloWorldExample
but simply in
/WEB-INF/classes/HelloWorldExample. This time tomcat found it. And here
is the error I got.
Why does the same servlet work under default package or even in
/examples-test but wont work under my webapp directory.

Read the notes at

and http://www.ccl.net/cca/software/UNIX/apache/tomcatfaq.shtml

Primarily check if your web.xml is correct and in correct place, if
your server.xml has an entry:
   !-- Apache AJP13 support. This is also used to shut down tomcat.
  --
Connector
className="org.apache.tomcat.service.PoolTcpConnector"
Parameter name="handler"

value="org.apache.tomcat.service.connector.Ajp13ConnectionHandler"/
Parameter name="port" value="8006"/
/Connector

and  you have
  Context path="/vitamin"
docBase="/usr/local/apache/htdocs/vitamin"
  crossContext="false"
  debug="0"
  reloadable="true" 
   /Context
there.


And if the port is for ajp13 is the same as in worker.properties file.
Check if your worker.properties are configured correctly for apj13
and if you are including the right file in the httpd.conf

Once you corrected/cheked everything restart kill apache, kill tomcat
start tomcat, start apache.

 Hi,

Hi :-)   from a email in Servlet-List, there is a sample code
for DBConnectionPool in the following link:
http://www.webdevelopersjournal.com/columns/connection_pool.html

and in Jason Hunter's book, from P266, there is also a sample of
ConnectionPool.

I think you need make getInstance() method "synchronized",
please see the first sample.

The following is just my understanding, as a reference:
( I use "MyServlet" to standard for my Servlet class,
  I use "MyHelper" to standard for DBConnectionPool)

*  the steps:
- the bytecode of MyHelper in MyHelper.class file
  (or in a database...)
- it is loaded by a classloader, now we have "a Class
  object of MyHelper", now this classloader holds a
  reference to this Class object, this Class object itself
  is a instance of "the class Class"
- several instances(or only one, for example, SingleTon in
   your code) of MyHelper  are/is made "from" that Class
   object. normally our Servlet holds the reference(s) to
   these/this instance(s). But with SingleTon mode, "the Class
   object of MyHelper" Also hold a reference to that
   OnlyOneInstance of MyHelper with a static field(in your
   code,  its name is "instance")

- the classloader of MyServlet may be Or may Not be the same
  one with that classloader who loads MyHelper. with
  jakarta-tomcat-4.0-b1, it depends on Where we put
  MyHelper.class(or MyHelper.jar) .

*  now there are several cases:
- MyServlet lose/release the reference(s)(for example, after
   reloading), now because "the Class object of MyHelper"
   Also hold a reference to that OnlyOneInstance of MyHelper
   with a static field (its name is "instance"), so "that
   OnlyOneInstance" will not be GCed.
 - if the classloader of MyHelper is destroied, then
"the Class object of MyHelper" is not there, but perhaps
that OnlyOneInstance is still there(if MyServlet still hold
a reference to it, or if we already put a reference to it into
ServletContext or somewhere else...), now perhaps our
code will get a Exception.

- if the classloader of MyServlet and MyHelper is the same
   one, now with jakarta-tomcat-4.0-b1, when MyServlet
   is reloaded, the classloader will be destroied, and so,
   MyHelper also lose its classloader.

- so if we want to let MyHelper live "Longer" than MyServlet,
   perhaps we need to load MyHelper with another classloader
   (for example, Shared classloader or "System classloader"  or
other)

- another question: if we use classloaderA(for example, an instance
  of URLClassLoader) to load MyHelper,  and we are sure that
  classloaderA  will not be destroied, then is it Possible that
  classloaderA will "unload" MyHelper and re-load it again?
  I am not sure, but I guess perhaps it is not possible. I find
  the following in "The Java Language Specification"(Second
  Edition): http://java.sun.com/docs/books/jls/

...
12.7 Unloading of Classes and Interfaces
An implementation of the Java programming language may unload
classes. A class or interface may be unloaded if and only if its
defining class loader may be reclaimed by the garbage collector as
discussed in 12.6. Classes and interfaces loaded by the bootstrap
loader may not be unloaded.Here is the rationale for the rule given
in the previous paragraph:

Class unloading is an optimization that helps reduce memory use.
Obviously, the semantics of a program should not depend on whether
and how a system chooses to implement an optimization such as class
unloading. To do otherwise would compromise the portability of
programs. Consequently, whether a class or interface has been
unloaded or not should be transparent to a program.

However, if a class or interface C was unloaded while its defining loader
was potentially reachable, then C might be reloaded. One could never
ensure that this would not happen. Even if the class was not referenced
by any other currently loaded class, it might be referenced by some class
or interface, D, that had not yet been loaded. When D is loaded by C's
defining loader, its execution might cause reloading of C.

Reloading may not be transparent

documentation

[tom]

Hi all,

I am new to this list and have been learning how to 
use Cocoon and Tomcat after getting interestedin XML. I have had 
real problems with all the documentation. Even Brett McLaughlin's book "Java and 
XML", which I bought,seems out of date already - and the instructions do 
not work (at least not when I try them).
This means that days, even weeksare wasted 
just trying to piece together enough information to get the basic tools up and 
running.
I do not mean this as criticism: preparing 
documentation is an enormous undertaking, especially doing it for people 
who might have a very "limited" - perhaps non-existent ;) - knowledge, and 
particularly when people preparing the documentation are so familiar with 
platforms, standards, OSes, programming etc.

The point I would like to make is that we need a 
new approach to documentation preparation:

1 the success of the "works out of the box" 
software brigade is precisely because it installs when double-clicked!! it may 
not do much else, it will almost certainly adhere to proprietary standards, but 
after the excruciatingly painful time I have had to get Cocoon and Tomcat 
working, just on a laptop, it is obvious why people stick with "out of the box" 
stuff;

2 IMHO a new publishing framework will only truly 
succeed when non-programmers etc like myself can access the new tools in a less 
painful way, gain familiarity with them and thinkof things to do with them 
- this might result in tools being used in ways that are less dominated by the 
IT industries various mentalities, and mean that Standards that are set (by eg 
W3C) prevail in the longer term;

3 the success of open source depends upon people 
with limited computer skills being able to specify and use open source tools in 
their projects, work etc. without having to run to their sysadmins, programmers 
etc every five minutes over what are, to the experienced, ridiculously simple 
problems;

4 there is also a problem with accessibility: many 
people use dial-up to access the internet; in a lot of countries, as here in the 
UK, that dial-up is not free of charge - this means that to spend hours trying 
to piece together the various, inconsistent sources of documentation, even the 
archives, to try and get a picture of how to get something up and running is so 
full of frustration and so expensive,that having "played" around for a 
while you just retreat and look at the old, proprietary ways of doing 
things;

These problems are not unique to this project, I 
have found it before - also with proprietary packages - as I am sure we all 
have. However, just as the internetworked world does not belong only to 
the corporates, neither does it belong only to people who are computer or 
software experts. The success of proprietary standards is not because 
people are lazy, but becausealternative tools are so 
inaccessible.

I would like to help to find a way of improving the 
documentation so that the tools are more accessible.

I repeat that this is not a criticism 
-documentation is a large task and who wants to do that when they are 
brilliant software engineers at the cutting edge ;) !! and have so little 
time.

I do not know how to proceed from here but would be 
willing to help out. 

I apologise to those who may consider this e-mail 
off-topic, but I just could not keep silent any longer.

Best wishes

Tom Nimmo

Re: Too many open files with Tomcat-3.2.1 under Solaris

[Ben Flaumenhaft]

Hi Zsolt,

Most UNIX systems need one file descriptor per open socket. That error
message almost always means you don't have enough file descriptors. In
Linux, at least the last time I checked, you need to recompile the kernel to
change the number of file descriptors allocated by the system. Under
Solaris, you can change it in /etc/system.

See:

http://www.rational.com/technotes/clearcase_html/ClearCase_html/technote_344
.html

I'd recommend bumping it to 1024 and see if your problem goes away.

Hope that helps.

Subject: Too many open files with Tomcat-3.2.1 under Solaris


 Hi,

 I just want to port our tomcat application to Solaris-2.7 and after a
 short time I get the error message "Too many open files" from
 java.net.SocketException.

 The same applications does not have the problem under Linux.

 I'm pretty sure that not our application causes the problem.

 I use j2sdk1_3_0_02 under Solaris.

 Any ideas?

Re: Life of a class?

[Ben Flaumenhaft]

Hi Neil,

Your pool class probably has a static member for the single instance
retrieved by getInstance (), right? If so, this instance is reset only when
the server is restarted or stopped, or when you explicitly release it
yourself.

(By the way, Tomcat maintains a separate classloader for each context (i.e.,
each webapp). Static variables exist within the classloader. This means if
you have multiple contexts, i.e., the same app instantiated several times in
the same Tomcat, you'll have several instances).

 Hi,

 We have implemented a database connection pool class (extract below) and
use
 the 'getInstance' method to ensuire that there is only one instance
created
 at any one time.

 What we need to know is when will this class be destroyed? Is it went the
 server is stopped (or crashed!) or will it timeout after a period of
 non-use?

 Regards,
 Neil


 public class DbPool extends Object implements java.io.Serializable {

 private static DbPool instance;

 public static DbPool getInstance(){
 if (instance == null)
 instance = new DbPool();
 return instance;
 }

 /** Creates new dbPool */

Re: RMI

[Sergey V. Udaltsov]

 I've just got my serlevt working as an RMI client. To do this I had to edit
 the tomcat.policy file to give all permissions to everything, and use the
 rmiSecurityManager. See my earlier posts for more info
So it is impossible to publish such a servlet without affecting base
Tomcat configuration, isn't it? That's pity:(
And I am not sure I want to give AllPermissions. Did you try to refine
the permissions?

Multiple Concurrent Servlet Initialization

[Arne Handt]

Hello All,

I know that this topic has been discussed about two months ago but I wasn't
able to find a hint helping me to solve my problem in the archive, so I
touch it again.
My problem: I have a multithreaded using W3C's Jigsaw HTTP Stack to access
my servlet (on Jakarta Tomcat v3.1) with multiple requests concurrently,
using the same URL (with a gap of about 20 ms between sending the requests).
This is, of course, no problem, when the servlet is already initialized, but
it leads to multiple servlet instantiation and initialization, if the
servlet has not been initialized before.
Is this a Tomcat bug or can it be switched off ? Can anyone help me ? Please
tell me if you need more information in order to help.
Thanks for your effort.

Best regards,
Arne

RE: Please help. Going Nuts.

[Jan Labanowski]

Again, My advice would be to put a simple HelloWorldExample.java servlet.
You probably have some complicated stuff. Keep it simple like:
--- cut -
/* $Id: HelloWorldExample.java,v 1.1.1.1 1999/10/09 00:19:59 duncan Exp $
 *  Modifed by jkl
 */

import java.io.*;
import java.text.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class HelloWorldExample extends HttpServlet {
  HttpServletResponse response)
throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();

out.println("html");
out.println("head");
out.println("titletest/title");
out.println("/head");
out.println("body bgcolor=\"yellow\"");
out.println("H1Hello there/H1BR");
out.println("/body");
out.println("/html");
}
}
--- cut -

in the /usr/local/apache/htdocs/vitamin/WEB-INF/classes
than do 
  javac HelloWorldExample.java
Assuming that you have the classpath to servlet.jar and your JDK classes set
it would produce HelloWorldExample.class in the same directory.
Then do:
   http://mymachine.com:8080/servlet/HelloWorldExample
and
   http://mymachine.com/servlet/HelloWorldExample
and see if you can see it working.

 Why does the same servlet work under default package or even in

 Read the notes at

 and http://www.ccl.net/cca/software/UNIX/apache/tomcatfaq.shtml
 
 Primarily check if your web.xml is correct and in correct place, if
 your server.xml has an entry:
!-- Apache AJP13 support. This is also used to shut down tomcat.

 Connector
 className="org.apache.tomcat.service.PoolTcpConnector"

 Parameter name="port" value="8006"/
 /Connector
 
 and  you have
   Context path="/vitamin"
 docBase="/usr/local/apache/htdocs/vitamin"
   crossContext="false"
   debug="0"
   reloadable="true" 
/Context
 there.
 
 
 And if the port is for ajp13 is the same as in worker.properties file.
 Check if your worker.properties are configured correctly for apj13
 and if you are including the right file in the httpd.conf
 
 Once you corrected/cheked everything restart kill apache, kill tomcat
 start tomcat, start apache.

RE: Log File isapi.log Too Big

[Randy Layman]

Sadly, no.  You must stop IIS, remove the file, and restart IIS.
Not to hard with a .bat file, however it causes outages in your
availability.

Batch file would be something like:
net stop "World Wide Web Publishing Service"
del isapi.log
net start "World Wide Web Publishing Service"

Once I got my server running, I turned the logging down to FATAL and
it doesn't seem to grow to much.

trouble in starting tomcat

Hi,
I've been using tomcat 3.2.1 successfully on win2k with jdk1.2.2. I was
having frequent tomcat crashes fromt the time I started having jdbc-odbc
connectivity in my servlets. I was thinking of changing my JVM to avoud the
crashes. and Now before I made any changes, the tomcat doesn't start at all.
or maybe I should say, it crashes immediately(I just get the glimpse of the
window).
What to do?

RE: trouble in starting tomcat

[Randy Layman]

First, try starting tomcat with bin\tomcat run (note the parameter
run) - this will start in the same window and will keep the error on screen.

Second, the cause of your crashes is the JDBC-OBDC bridge.  This
component is not thread safe.  As soon as the second concurrent access is
attempted, a crash occurs.  You must either serialize your requests
(completely, you can only have one connection object at a time) or find
another way to access your data.

RE: Servlet and JDBC driver problems

[Mike Braden]

You need to make the oracle jdbc drivers avaiable in either the classpath
or in the lib dir of the webapp you are using ( webapps/myapp/WEB-INF/lib ).

I have been successful using the thin driver.  The oci8 driver needs to
have access to the oracle libraries while the thin driver only needs the
odbc class files.

The oracle classes crash tomcat if you put them in $TOMCAT_HOME/lib
