You could try jedit http://www.jedit.org

There is a plug-in for tomcat.

Taglib help. FunkNewbiest

[Qmail List]

Hello,

I'm trying to implement TagLib functionality into a webapp for the first
time. Everything seems correct, and I've been through a million sites and
tutorials. Yet I always get the following error upon loading the page (TC
4.1.12 / JDK 1.4.0_01):

org.apache.jasper.JasperException: /en/archiver.jsp(259,18) Unable to load
class ArchivePanel

Here are my files and setup. Can anyone see the problem? (I've seen some
archive responses related to v1.1 or v1.2 of the tld dtd. also, the machine
doesn't need internet connectivity does it? - to get those dtd's?). Finally
how can I enable jasper logging in TC4. That may help, but I don't see the
option in server.xml

 TIA - Eric


archiver.jsp

<%@ taglib uri="/WEB-INF/display.tld" prefix="display" %>

some html and later in page..




web.xml

   throw new JspTagException("SimpleTag: " + ex.getMessage());
  }
  return SKIP_BODY;
 }

 public int doEndTag() {
  return EVAL_PAGE;
 }

}


If I try to troubleshoot myself I still get no where. For example, If I
change the jsp page to read



I get the following error: No such tag ArchivePannn in the tag library
imported with prefix display.

So things are working to some extent. Everything compiles, everything is in
the correct location. No typos I can see. Heh. I'm at a loss.

Cookies translation problem on isapi connector using IIS5 + TOMCAT 4.0.1

[Zaragoza, Carles]

Dear all,

Look like that when I use IIS with AJP3 and TomCat 4.0.1 with the
isapi_redirect.dll cookies can become HTTP translated and/or truncated. 

This ugly HTTP translation occurs during request communication between the
isapi_redirect.dll and Tomcat.

Cookie truncation occurs when multiple cookies are used. I think that this
is a side-effect of the HTTP/1.1 extended cookie definition. 

So for example "MY_KEY_VALUE=815" on TomCat working alone becomes
"MY%5fKEY%5fVALUE%3d815" on IIS + Tomcat. WHY ?

I believe, that the connector architecture between IIS and Tomcat is the
cause.  It is sending the raw HTTP to Tomcat.  This is not "automatically"
reversing the escaping of the special characters (ie. Multiple cookies
separation character's)).

Could any connector-guru help me in order to understand what is going on ?

Any help will be much appreciated.
Carles.

It all depends on what kind of access you are trying to protect.  If
this is a low-security thing, it might be useful to be able to mail
users their passwords if they forget them.  In that case you would store
them in plain text.  If it's higher security, you might store them as a
SHA1 hash, so that if they lose a password, they have to have a new one
generated.  If it's even higher security, maybe you shouldn't be using
passwords at all.  As in ALL areas related to security, how you do it
depends on the value of what you are trying to protect.

RE: storing passwords

[Steven Sporen]

Normally you generate a hash of the password and store that. Thus the
actual password is not stored, then when a user logs in you generate a
hash and compare the two.

Re: storing passwords

[Richard Johnstone]

You could just store them in your database.
All you need to do is encrypt them using a simple encryption method

  public static byte[] encrypt(String x) throws Exception
  {
 java.security.MessageDigest d =null;
 d = java.security.MessageDigest.getInstance("SHA-1");
 d.reset();
 d.update(x.getBytes());
 return  d.digest();
  }

can a Tomcat Filter rewrite the URL ?

[Stephen Riek]

I'd like for a request to "/en/Folder/File" to be mapped to 
"/Folder/File" but with a parameter 'lang' set to 'en'. 
Likewise, a request to "/fr/Folder/File" to be mapped to 
"/Folder/File" but with a parameter 'lang' set to 'fr'.
Is this possible with Filters?
If not, is there any way to accomplish this within Tomcat so that it works for any 
number of directories and subdirectories. The reason I want to do this is to avoid 
copying/pasting an entire sitemap to support a second language - I know that some 
people create a site in English then copy/paste the directory tree to support a second 
language but this is not scalable and difficult to maintain.  
Other mechanisms I've looked at are Apache rewrite rules but they're very complicated. 
 
Any and all help much appreciated. Thank you.
Stephen.

Session already invalidated error

[Tejas Bavishi]

Hi,

I am using Tomcat 404 and OC4J on Windows .

When I send approximately 25 requests, very often tomcat returns the
following error :

HTTP/1.1 500 Internal Server Error
Content-Type: text/html;charset=ISO-8859-1
Connection: close
Connection: close

Apache Tomcat/4.0.4 - Error
report
Apache Tomcat/4.0.4 - HTTP Status 500 - Internal Server
Errortype Exception
reportmessage Internal Server
Errordescription The server encountered an internal
error (Internal Server Error) that prevented it from fulfilling this
request.exception java.lang.IllegalStateException:
getAttribute: Session already invalidated   at

org.apache.catalina.session.StandardSessionFacade.getAttribute(StandardSessi
onFacade.java:171)  at
org.apache.catalina.session.StandardSessionFacade.getAttribute(StandardSessi
onFacade.java:17


Now the HTTP request is very simple, the requests call a single JSP page
which in turn calls taglibs, which in turn calls EJBs to retrieve data from
database and then return the HTML to the client. I have narrowed down the
problem on to Tomcat / my code running on Tomcat. However, my problem I am
not able to figure out, where the problem is ? I have checked mail archives
on this list, but haven't really found out any real pointers yet 

Any help/pointers on this highly appreciated

Many Thanks,
Tejas

Re: storing passwords

[RXZ JLo]

Thanks to all of you for the responses. 

apart from this password I will be storing some other
things too(they too are passwords but for some other
things in the application). I cant use one way hash as
I cant use them further. what mechanism should I
follow in this case?

Also, for the login case should I bother about
encryption in the login form? Can I just use
 and rely on the brower?
What are the pros and cons for this? If you see yahoo
login, they generate md5 using javascript on the
client side itself - is this really necessary?


Thanks again.

multiple jservs with one apache web server

[ranjit]

Hello Group,

I want to mount multiple JServ engines on a single Apache Web Server, on 
the same server. To do this I have installed Apache web server (WITHOUT 
DSO support) and five JServ engines (jserv1,2,3,4,5). 
  
The reason why I want to do this is, we have a java-servlet based intranet 
mailing system, which very often goes down as the number of users using 
it is increasing rapidly... it was till now working on one apache and one 
jserv engine. 

Now can anybody help me as how to mount these five jservs on different 
ports on apache web server with a single IP. Any sample code/configuration 
clues/details will help me alot... 

The apache webserver version I am using is apache_1.3.27 and jserv1.1.2 
and jsdk 2.0 

 many thanks,
 Ranjit.

It's all  qualified.  As the first response to your question said, it

SSL, redirectPort, and transport-guarantee, oh my!

[Shatzer, Larry]

I'm trying to set up redirection to SSL. Below are the appropriate sections
of web.xml and server.xml

When I go to https://localhost:8443/app, I get directed to my login page,
with the addition of a jsessionid to the url.

If I go to http://localhost:8080/app, it warns me I am going to a secure
page (I have this turned on to know when I am going in and out of ssl).

I then get the security alert about the SSL certificate, I click YES to
proceed, it sits there for a while. In my status bar, I see it's trying to
connect to 127.0.0.1, which is no big deal, since it's localhost.

When it eventually times out, my url is now
https://localhost:8080/app/security/login/jsp/login.jsp;jesssionid=sessionid
here

Now, if I change it back to http in the url, and leave the rest, (mainly the
jsessionid), it will redirect fine.

I am running Tomcat 4.0.6.

Also, ran across this in the archives:
http://archives.apache.org/eyebrowse/ReadMsg?[EMAIL PROTECTED]
ache.org&msgId=285554 which had no answer that I could find. His situation
seems close to mine, expect the fact, if I remove auth-constraint, it breaks
the application.

Any thoughts or help on this would be appreciated.

Re: does tomcat automatically revert to url rewriting...

Will tomcat *automatically* go through the effort of rewriting the URL
if the session *cannot* be persisted via the cookie?(i.e. do I need to

are not there then it encodes each request for me?)

   


Tomcat does indeed know if a session id cookie was received (and you can
find out as well, by calling request.isSessionIdFromCookie()).  If that is
the case, response.encodeURL() and response.encodeRedirectURL() will
return the argument unmodified.
 

OK. So that means I don't need to be concerned with when I should use 
the call(s) and when I should not - I should always wrap my links and 
redirects in these calls. (assuming my application uses sessions)

One subtlety should be pointed out, though -- consider what happens on the
very first response for a new session.  At that point in time, Tomcat has
no idea whether the client supports cookies or not.  Therefore, it sends
the session id both ways (rewriting and a cookie).  On subsequent
requests, if the cookie has been returned, Tomcat will stop rewriting.
 

ok.


We also need to remember that Tomcat does *not* scan the output your
servlet or JSP page creates, and modifies the hyperlinks.  If you do not
call encodeURL() or encodeRedirectURL() yourself when creating the output,
URL rewriting will never occur (and your app will require the client to
support cookies if it uses sessions).
 

ok. I've got that.

Now, I am using struts 1.1b2 so if I have  tags (and the 
others tags which render urls) embedded in my jsps, should I wrap these 
tags manually or does struts do the wrapping? If struts automatically 
does it for me (as the docs suggest) then the above answer for me (using 
struts) is not relevent.

Correct?

I cannot get tomcat to unpack any .war files I give.
I cannot get tomcat to process any .jsp files it has.

I am running Tomcat 4.0.4 for OpenVMS!  I'm hoping it's not an

RE: SSL, redirectPort, and transport-guarantee, oh my!

[mech]

Welcome to the land of Internet Explorer. I bet you use Internet
Explorer, don't you? 
Try Mozilla/Opera and you will see that I works fine.
Some people didn't trust me yet that this problem you describe is a
bug...

Follow these links to find out more:

http://www.mail-archive.com/tomcat-user@jakarta.apache.org/msg74000.html
http://www.mail-archive.com/tomcat-user@jakarta.apache.org/msg74194.html
http://www.mail-archive.com/tomcat-user@jakarta.apache.org/msg73632.html

Your after-timeout url with https:/host:8080 confirms me in my opinion
that IE only changes the protocol from http to https instead of changing
the port numbers, too. Don't know if it has something to do with the
sessionids, too.

That's the reason why the workaround works. If you change Tomcat to
protocol standard ports 80/443 you will see that your problem disappears
because the port numbers won't matter when changing the url for the ssl
redirection.


You may consider adding your experiences to the bug database. Maybe
something could be done from Tomcat side, too:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=13861

(Especially the issue after timing out is new and confirms the IE
problem, but it might have something to do with the session, too...)

Apache 2.0.43 with SSL and Tomcat 4.1.12 problems

John,

Thanks for your help, I have re-installed and configured all my apache 
software under e:\apache, and everything now works (after 38 hours of
hard 
graft!) HOWEVER I had to remove the full path for mod_jk i.e.

It was ... LoadModule jk_module e:/apache/apache2/modules/mod_jk.dll

I changed it to ... LoadModule jk_module  modules/mod_jk.dll

I had only bothered pathing it cos in 70% of the HOTO's that I have read

said that it was a bit temperamental on the pathing!

kind regards

RE: mod_jk : worker not found

[Turner, John]

 
No, that's not correct, unless mod_jk can only use "ajp13" for some reason.
As long as the worker on the JkMount line equals the worker defined in
workers.properties, it should be good to go.  

If mod_jk was restricted to only using "ajp13" you'd never be able to do
load balancing, because you'd never be able to define more than one worker.

For example:  http://www.ubeans.com/tomcat

Tomcat 3.3.1 in Windows occupies 100 % CPU

[Surendra Kumar]

Hi all
  We are using Apache 1.3.26 + Tomcat 3.3.1 in W2K  Professional platform.
  During some servlet operations the CPU usage of Tomcat process becomes 100 % and it 
stays there for  long (even days).

  Did anyone face this kind of problems ? Please let me know how to debug this.

  I also like to know, how to take thread dump of tomcat process. Since tomcat is 
running as windows service i could not use
  the normal sequence ( ctrl + break).

  Thanks for any help on this regard.

RE: please help me

[Michael Echerer]

To use servlets you will need a servlet container/webserver like Tomcat. To compile 
servlets some .jar files from Tomcat are necessary. You have to add this to your 
classpath or use ant scripts whatever.

In your case I guess that servlet.jar from /tomcat/common/lib/ is missing in your 
classpath when your try to compile your servlet classes.

You'll have to include servlet.jar in your CLASSPATH.
servlet.jar is part of your tomcat distribution. When using
Tomcat 4.1 you can find it in $CATALINA_HOME/common/libs

Tomcat with external JBoss (JNDI problems)...

[Andrzej Jan Taramina]

I've got Tomcat 4.1.12 and JBoss 3.0.4 running on separate machines/VMs.

I've put a jndi.properties file pointing to the JBoss JNDI server in my WEB-
INF/classes directorybut my servlet does not pick it up for some 
reasonand just grabs Tomcats JNDI instance instead.

Anyone know how to set this up so my servlet can get an IntialContext that 
points to the JBoss server (that is, so that it finds the jndi.properties file)?

Thanks!

Re: SOAP: Unable to resolve target object

[jattwood]

Hi Phil,

>Exception in thread "main" java.lang.NoClassDefFoundError: 
>
>I put this /webapps/soap/WEB-INF/classes in the CLASSPATH (in
>case).

Your client will rely on the CLASSPATH to find its classes (unlike the
server which uses TomCat's class loader hierarchy). Whenever I've had problems
like this they've always turned out to be typos in my CLASSPATH (missing
semicolon or colon instead of semicolon) which invalidate the part which points
to the class which can't be found. These can be very hard to spot, and even
harder for the person who "knows" what should be there. I have a Perl script
which breaks my classpath into pieces on semicolons and display each on a 
separate line. This helps to show up errors, but still doesn't help when the
problem is a typo inside one of the path components rather than the 
separators.

Hopefully a second pair of eyes will resolve your problem,
Regards,

John.

Para: Tomcat Users List
Asunto: Oracle Connection Pool - Global Naming Resource - HOW TO


I had problems earlier getting a Global Naming Resource database connection
pool to work with my Oracle db. The only reply I got was that someone else
had the same problem!

I now have it working, so for those interested, here is the HOW TO:

When defining the parameters for the db pool (say TESTdb) ensure that the
maxActive parameter is not set too high, i.e. that Oracle has enough
connections available for the pool (Oracle config parameter
max_connections). Mine was set to 100 in server.xml, and when the pool tried
to establish itself, it just sat and waited for 100 connections to become
available!

Every app that wants to use the connection pool should have a Context entry
in server.xml containing a ResourceLink to the name of the pool.



The application can then connect using:
  
Context ctx = null;
ctx = new InitialContext();
  Context envCtx = (Context) ctx.lookup("java:/comp/env/");
DataSource ds = (DataSource) envCtx.lookup("/testDb");
Connection conn = ds.getConnection();

No entries are required in the application web.xml to reference the
resource.

Have Fun!

RE: multiple jservs with one apache web server

ApJServMount /servlet ajpv12://some.server.com:8010/servlet

Add ApJServMount commands as necessary, changing the port number on the

If you are talking about trying to load balance, where you have multiple
ApJServMount commands for one Apache Virtual Host, then I think you may be
out of luck.

HttpSessionContext deprecation question

[jfc]

Hi,

I see that this class is now deprecated with the 2.1 servlet api.

Can someone please explain to me briefly why this is? I know its down to 
security but a little more of the theory behind the decision would be 
interesting.

I am trying to provide the functionality to admin users of our site and 
have found that its easy to achieve(storing user objects in the app 
scope as users enter the site or login) but before I go ahead and make 
it available, I thought I'd better check.

thanks

p.put(InitialContext.PROVIDER_URL,"yourservername");
InitialContext context = new InitialContext(p);


After that you can do your EJB lookup's with that context.

Subject: Tomcat with external JBoss (JNDI problems)...

I've got Tomcat 4.1.12 and JBoss 3.0.4 running on separate machines/VMs.

I've put a jndi.properties file pointing to the JBoss JNDI server in my
WEB-
INF/classes directorybut my servlet does not pick it up for some 
reasonand just grabs Tomcats JNDI instance instead.

Anyone know how to set this up so my servlet can get an IntialContext
that 
points to the JBoss server (that is, so that it finds the
jndi.properties file)?

Thanks!

Tomcat Configuration

[Martin Klebermaß]

Hi everyone, im quite a new Tomcat user, so not realy fitt in everything.
Because i have to set up Tomcat for a new customer in a shared hosting environment, i 
dont want to waste ports ( as it is generated automaticly) so i tryed to close 
the Shutdown Port of the Tomcat Server which is definied in the  Statement.   
I had a look at google and quite a lot other resources but couldnt find out how to 
close the port ( or better how to not open the port on startup ;)  )


Perhaps anyone here can help me with a simple sollution.

cya Martin


p.s.: beside this if anyone knows good solutions for tomcat in shared hosting 
environments ( with running a tomcat for each user under his own user_id for the most 
security) perhaps he can give me a hint ;)

A style question in this regard -- is the general practice for this:

1. To use a unique variable for each URL that needs to be encoded
2. To put all URLs into a list/array, then refer to them by their key in the page
3. To use a single variable name and just call encodeURL immediately before the point 
where the name is used, then echo the variable name to the browser
4. Not to use a variable name at all but rather just call echo encodeURL's output 
directly to the page



Just curious,

Have you considered LDAP?  I haven't used it myself but it might be a better solution 
if you have to store a variety of user information that will be used in more than one 
context.

Generating the md5 on the client side doesn't really do too much, since if I know the 
MD5 then basically I know the password.  I just can't type it into Yahoo's UI since 
then *that* will get MD5'd and it will change the value sent.  (Of course, I could use 
Mozilla and disable the JavaScript that does this... or write my own page... etc.)

If you use SSL then you don't need to do the JavaScript trick -- the passwords will be 
sent over the wire encrypted.  But if you can't or don't want to use SSL, then just 
remember that it is SUPER easy to listen in on HTTP connections and watch the data go 
back and forth.  There's dozens of scripts that basically do this and hunt down likely 
passwords.  So you want to implement *some* level of encryption unless everything 
you're doing is within a "secure" environment like behind a corporate firewall (note 
the quotes, that indicates a level of facetiousness).

I really like NetBeans 3.4 and I use it at work on the Win2k box (yes, it has the 
memory).  But on my Mac it is very sluggish, as most Pure Java apps are.  I only have 
a G3 w/384 MB RAM.  I assume it performs better on the G4?  (If NetBeans ran as fast 
on MacOSX as it does on Windows I'd be really happy.)

Error message meaning?

[Ben Ricker]

I am using mod_jk 1.2 with Apache 1.2.27 talking with 4 Tomcat 4.0.6
instances.

Every once in while, I get tthe following error logged to mod_jk:

[jk_ajp_common.c (961)]: Error ajp_process_callback - write failed

What exactly does this mean? Is it that mod_jk had an error writing to
the stream to Tomcat? If so, does it retry the request it sent? How does
one know it was successful? Also, this occurs fairly rarely and
intermittently. Out of 26,000 requests, I see it 70 times on one day.

Thanks,

dynamically built "server.xml"

[PERRIN GOURON Olivier]

Hello,
I'm trying tomcat4.1 to run my application, and I need to define contexts
dynamically. I know this is done in server.xml, but the point is that my
/conf directory, where server.xml remains is read-only...  So, I think of 2
possibilities:
+tell tomcat not to look in /conf dir, but in another one I could
write in
+Inside server.xml, reference external documents that would be
replaced when tomcat reads server.xml Are these two solutions possible with
tomcat - and how ?
any third idea?

As far as I know, that error shows up when the user has closed their browser
or browsed to another page before the request was completed.

Someone please correct me if I am wrong, as I get the same error message,
but have always ignored it due to the reason above.

Global Resource Def & JDBC Pool

[Jason Jonas]

Hey All,

I'm having some difficulty getting Tomcat to establish a connection to
a database and I need a second pair of eyes on this...

Environment:
  Windoze XP
  Tomcat 4.1
  MySQL 3.23.53
  MM JDBC Drivers 2.0.14

Global Resource Def (created through /admin):
  JNDI Name: jforumdb
  URL: jdbc:mysql://localhost/jforum
  Driver: com.mysql.jdbc.Driver

web.xml:
  
jdbc/jforumdb
javax.sql.DataSource
Container
  

context.xml: (passed in to Tomcat via ant install/reload)
  

  

Code to get a connection:
  InitialContext ic = new InitialContext();
  DataSource ds = (DataSource)
ic.lookup("java:comp/env/jdbc/jforumdb");
  con = ds.getConnection();

Result of getting a connection:
java.sql.SQLException: Cannot connect to MySQL server on
localhost:3306. Is there a MySQL server running on the
machine/port you are trying to connect to?
(java.net.BindException)


I've tried connecting to a Pointbase DB with the same results. I am
able to make a direct connection to any database without any problems
whatsoever. I don't think it's a web-app/Tomcat config issue because
I'm able to get as far as Tomcat *trying* to connect to the DB. So I'm
thinking it's some other config issue. Maybe it's an XP-thing?

Any and all info is appreciated. Thanks!

Jason

I read the docs, but couldn't find any solution but those I mentioned
My problem is that I run Tomcat from a CD-ROM...
I actually need to use "virtual" directories, which I want to define each

RE: Global Resource Def & JDBC Pool

[Oliver Meyn]

Hi Jason,

I think you're right that this isn't tomcat - this error has only appeared
for me when either the dbase really isn't there (yes, I've forgotten to
start it, *sigh*), or more often, port 3306 is closed/filtered.  With XP you
might be having firewall issues (dunno how configurable it is, although on
Home I think it's on/off, *sigh*), or maybe the user tomcat is running as
isn't authorized?

I'd try running nmap first and if 3306 is closed then you know the problem,
and can start figuring out a solution.

Cheers,
Oliver

Sun JDK 1.4 production quality?

[Ben Ricker]

I have heard a number of differing opinions about the stability of 1.4.x
version of Sun's JDK. I wanted to see if anyone runs Tomcat using 1.4.x
and how they have found its stability, speed, etc. 

I know there have been a number of enhancements in 1.4 which sound
intriguing; additionally, its jdbc driver fixes a bug that is curretnly
vexing us. Our Tomcat installation gets roughly 25,000 hits a day; if
you can include an approximate idea of how many hits your app takes,
this information would be helpful.

I would, of course, test this with load testing, but the management here
seems to think we do not need it*sigh*

Thanks,

Ben Ricker

RE: Sun JDK 1.4 production quality?

[Shapira, Yoav]

Hi,
It's good.  Stability is the same as before, it seems.  Speed has
improved.  GC has markedly improved, although we did have to experiment
a bit with the new GC options.

Our busiest system takes roughly 7000 hits a day, so not as busy as you,
but not idle either ;)

Re: i am having trouble using Java Beans with Tomcat 4.1

A little of topic - Global e-mail sending facility inside oftomcat?

[Ryan Cornia]

This is a little of topic, but I'm sure someone on this list has
implemented something similar with tomcat.
-->
I have several applications running on Tomcat 4.1.12 that I need to add
the capability to send e-mail via a SMTP server. There are two problems
-

1.) Are there any products or open source projects available that will
que the mail in case the SMTP server is down and re-send it later,
including the possibility of a tomcat re-start before the SMTP server
comes back up? Basically I want a way to insure an automated e-mail is
sent when a person registers, and is not "lost" when the e-mail server
is down.

2.) Is there a way to configure this service as a global JNDI resource
available to all applications running inside of tomcat?

Thanks,
Ryan

uri mapping question

[David Boyer]

I'm using the isapi_redirector2.dll (v2.01) and I've got it working, with one 
exception:
 
I want to map a uri such as "[uri:/students/*/servlet/*]" so that it includes all 
subfolders in the "/students" directory. Is this possible?
 
I know I could create a separate mapping for each student, but we have 1,300 students 
for whom I'd need to do this.
 
Any thoughts?

JNDI name space conventions

[Jonathan Williamson]

I'm trying to write some code that uses JNDI to look
up a JDBC DataSource to get a Connection.

My code works fine in Tomcat 4.1 if I use the
java:comp/env naming context, as in the following
code:

  Context initContext = new InitialContext();
  DataSource ds =
(DataSource)initContext.lookup("java:comp/env/jdbc/myoracledb");

If I try to run this in JRun 4 or Oracle 9iAS, I get a
NamingException.  Instead I have to do it like this
(doesn't work in Tomcat):

  Context initContext = new InitialContext();
  DataSource ds =
(DataSource)initContext.lookup("jdbc/myoracledb");

I found this article on Macromedia's web site that
sort of describes the problem I'm having:
http://www.macromedia.com/v1/Handlers/index.cfm?ID=22927&Method=Full

They say there that according to the Servlet 2.3
specification, JNDI lookups should be relative to
java:comp/env anyway.  I have a printed copy of the
Servlet 2.3 specification, and from what I've seen by
skimming through it, jndi naming contexts aren't
mentioned at all (I could be wrong there though).

Is this configured by some sort of setting in Tomcat? 
I can't seem to find one, or anything in the manuals
for that matter.

Thanks,
Jonathan

RE: A little of topic - Global e-mail sending facility inside of tomcat?

[Turner, John]

Any SMTP server will queue the mail for you automatically.  That's built-in
to the protocol.

I'm not sure I understand what you're looking for...it sounds like you are
looking for a SMTP server written in Java. There are plenty of free, open
source SMTP mailers out there, but if you need it in Java, that would be the
JavaMail API: http://java.sun.com/products/javamail/, most likely
com.sun.mail.SMTPTransport.sendMessage(Message message, Address[]
addresses).

I don't think JavaMail offers any queueing or redundancy, but you can use a
simple database operation...insert a record just before the message is sent,
send the message, and trap any exceptions.  If no exceptions, mark the new
record as "sent".  Periodically, have a process look in the database for
records that have an exception, then attempt to resend them, assuming the
logged exception is "server down" and not "user unknown" or something else
that would prohibit the email from being sent.

John

Doesn't work.it still does not pick up my JBoss-specific jndi.properties file.  
I've got that file in the WEB-INF/classes and the shared/classes directories...to 
no avail.

That works for me too Michaelhas for some time now.  The issue I have with 
it is that I don't want to hard-code the JBoss server URL's and such into my 
code, since then the servlet can't be deployed by others with different setups 
without a code change and a recompile.

What I am trying to figure out is how to just do a:

   InitialContext context = new InitialContext();

call...without the hardcoded properties objectand have it pick up the 
properties from the jndi.properties file...like it's supposed to.

Thanks!

I use this method instead of using the jndi.properties file.  See my

I ran into the same problem and decided to address this by making all of
the parameters JNDI environment variables and configuring those params
in my web.xml file.  I can easily change the configuration by commenting
out or changing the environment entries in my web.xml file.  Eventually,
I want to run with the integrated JBoss and Tomcat solution, but I had
some problems with them running together and decided to run them
separately and use this configuration until I can get the integrated
solution running correctly.

One approach would be to map your Filter to URL pattern "/*" so that it
sees every request.  On each request, you would look at the request URI to
see if this is one that should be remapped.  If not, just call
chain.doFilter() in the usual way.

If you see that this one should be overwritten, you'll want to create a
custom HttpServletRequestWrapper class that overrides all the path related
methods (getRequestURI(), getServletPath(), getPathInfo(), and so on) to
return the adjusted values.  Finally, grab a RequestDispatcher to the
modified path (such as "/Folder/File" and call its forward() method,
instead of calling chain.doFilter().

Re: Tomcat with external JBoss (JNDI problems)...

[Anthony Geoghegan]

Since the local TOMCAT JNDI server is not compatible with the JBOSS JNDI
server you probably have the -nonaming switch activated.
Since this deactivates the TOMCAT JNDI server you can access the local JNDI
properties that way.

Anthony Geoghegan.

You'd need to write a servlet that makes the same kinds of internal calls
that the admin webapp does (via JMX MBeans) to accomplish those kinds of
things.  Don't forget to declare the webapp as privileged (and spell it
correctly :-).

The reason you're not finding this in the servlet spec is because it's in
the J2EE Platform Spec, in the chapter on Naming.  Tomcat implements its
JNDI naming context in a manner that is consistent with this.

Go about halfway down the following page for links to the specs, and grab
the one for J2EE 1.3 (corresponds to Servlet 2.3 and JSP 1.2, which is
what Tomcat 4.x implements):

  http://java.sun.com/j2ee/download.html

I'm looking at a similar approach...but instead I want to manually read the

When a SMTP server accepts an email, it  should never loose it. If yours does, 
replace it . There are a lot of good quality Open Source SMTP servers.

Your program should not duplicate a SMTP server. If the SMTP server is down, 
you should get an exception (I don't know the JavaMail API) and maybe try to 
connect to a backup mailer.

You can never garantee that an email will reach its destination. Maybe the 
SMTP server of the receipient stores all email in /dev/null, you have no way 
of knowing and can't do anything about it.
If there is an error, the destination SMTP server will normally report an 
error back to you - for example: the user is unknown - and maybe your 
application should handle these bounce messages.

Welcome to the internet. Sometimes it's a disadvantage that nobody controls 
it, mostly it's a blessing.

Cees.

JkMount question

[Rafael Angarita]

   Hi,

   Does anybody knows if it's important the order of JkMount 
directives?, for example:

   I have two tomcat instances T1 and T2,  
   - The loadbalancer should handle all the requests to the entire site 
(and do a load balance between  T1 and T2) except for /app1 context
   - T2 should handle all the requests to /app1 context

   What's the right order of JkMount directives in my .conf file? does 
it matters?

   Thanks in advance,

RE: Tomcat with external JBoss (JNDI problems)...Workaround...

[Andrzej Jan Taramina]

I've come up with a workaround to the problem that Tomcat servlets can't seem to find 
the jndi.properties file and 
thus connect to an external JBoss server.

Hardcoding the properties works, but is ugly since then your code is tied to the 
specific location of the JBoss 
server.and thus requries code changes and a recompile to deploy elsewhere.

Michael's suggestion of putting the jndi info into the web.xml file would work, but 
has the disadvantage of being yet 
another detail that is not standard that deployers would have to look into.

My workaround let's you put your jndi.properties file into /WEB-INF/classes as you 
would expectand that's all you 
need do.  The code is quite simple:

Properties props = new Properties();
props.load( servlet.getServletContext().getResourceAsStream( 
"/WEB-INF/classes/jndi.properties" ) );
InitialContext  ctx = new InitialContext( props );

All it requires is that you have a reference to the servlet so you can do the 
getServletContext() call.  That was a bit of 
a PITA for me...since the jmx-console code did not pass this into the class that 
needed the JNDI context...but that 
was pretty easily fixed.

I still think it should read the jndi.properties file without this workaround!

Meaning of mod_jk.log times

[Ben Ricker]

I see a lot of msgs logged to mod_jk.log on the Apache servers we have
setup using mod_jk 1.2 (with Apache 1.3.27). It is talking to 4 Tomcat
instances running Tomcat 4.0.6.

I am wondering what exactly the time stamped at the end of the line says
exactly:

[Fri Nov 22 14:42:36 2002] loadbalancer web2.wellinx.com 0.018557

Namely, the "0.18557".I am assuming it is the amount of time it takes
the transaction from when mod_jk makes the request to Tomcat to when it
gets that info back.

Also, notice the "web2.wellinx.com"; that is the ServerName from the
Apache server. Is there a way to actually log the Tomcat instance the
request is going to? I know what Apache server I am looking at when I am
reading the lod, so the information there seems rather trivial.

Thanks,

Ben Ricker

What conclusions did you come to? My understanding is that 
ConcMarkSweepGC might be helpful for Tomcat, since you could avoid the

while it's garbage collecting.

Prblm: Tomcat doesn't start on boot, JAVA_HOME not defined. Manually works fine.

[Ola Theander]

Dear subscribers.

I have a problem that my Tomcat 4.0.4 installation doesn't start on
boot. In the boot.msg file I get a record stating that the JAVA_HOME
environment variable is not defined and therefore Tomcat can't start.
The strange thing is that the JAVA_HOME is defined in the profile.local
file. If I log on directly after the boot and run the tomcat startup
script from /etc/rc.d manually the Tomcat server starts as expected.
Therefore I suspect that the problem is either that profile.local is
evaluated after the Tomcat startup script when booting or the
profile.local environment variables aren't available during boot for
some reason.

Any help on this matter would be greatly appreciated.

Kind regards, Ola Theander

yep. I had an issue like this also - your JAVA_HOME should point to the
J2SDK/JRE directory, not inside to the bin directory. 

Also (and someone correct me if I am wrong) your JAVA_HOME should only have
a single path on it.

Set your JAVA_HOME in /etc/profile and not profile.local 

profile.local will probably only be executed when a user logs in, as
it's local to whatever user is logging in.

Fortunately, there is a yet-undocumented-method :( that works much better.

The "ServerLifecycleListener" in the "server.xml" file takes an
(undocumented) attribute called 'descriptors'.  The value is a ';' separated
list of resources to load the mbean-descriptors from.  This allows you to
package your mbeans-descriptors.xml file with the jar that contains the
custom Realm.  You just create your own mbeans-descriptors.xml file with
your Realm, and in "server.xml" set:
 

and all of your custom classes will be registered.  It works great for me.

RE: Tomcat Windows installer reports wrong JAVA_HOME variable

[john delby]

I removed the bin part from HOME_JAVA.
Here's some problems I noticed. I compared my unsucessful install on XP to a 
successful install on a Windows 2000 machine.

- Somewhere along the installation a copy file fails. I think the installer 
is trying to put something in common\lib. In the Windows 2000 machine, this 
is where a little copy windows shows up for 2 seconds in the middle of the 
install. I don't know if this part is using some java component. In XP, it 
doesn't happen. Installer reports copy failed for 2 seconds and continues 
extracting files.

After installation, I try catalina.bat and it tells me the Java environment 
is incorrect, shows some java variables and last line says something about 
-dJava.endorsement... not available.

The problem must be related to failed copy during installation. I 
reinstalled the java sdk many times and rebooted many times. I tried older 
versions of Tomcat and all had copy failed. So I guess it's a problem in my 
system. Don't what. I am logged in as administrator and installed also on 
FAT partition but always same problem.

after the install is done. When I run catalina.bat it tells me that the

yep. I had an issue like this also - your JAVA_HOME should point to the
J2SDK/JRE directory, not inside to the bin directory.

Also (and someone correct me if I am wrong) your JAVA_HOME should only have
a single path on it.

My Java environment variable, JAVA_HOME, on my Windows XP is
k:\j2sdk14;%JAVA_HOME%\bin

Yet Tomcat 4.1.12 Windows installer displays "Using Java Development Kit
found in k:\k2sdk14;k:\k2sdk14;k:\k2sdk14;%JAVA_HOME%\bin\bin\bin"

Why is it doing this? Where are the three bin's in "%JAVA_HOME%
\bin\bin\bin" coming from?

Tomcat 3.3 , JNDI, DataSource, Web.xml, Server.xml

[Jeovanny Mejia]

Does anyone know how to get a DataSource configured in the Server.xml file, 
reference it in the web.xml as a resource, and pull the DataSource using 
JNDI in an external application?

I am stumped.

If relative, it should be from the base of apache.
Is D:\javawork\apache\ your apache serverroot?

Anyway, try the absolute path.

AFAIK the JNDI resources stuff is not supported by Tomcat 3.3.  You should
still be able to use things like PoolMan within a webapp, configuring them
as described in the docs.

For 4.0 and 4.1, the appropriate docs are in the "tomcat-docs" webapp, and
also available online:

  http://jakarta.apache.org/tomcat/tomcat-4.0-doc/jndi-resources-howto.html

  http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-resources-howto.html

For 4.1, there are also some specific examples for data sources:

ClassCastException when using Tomcat as RMI client

[Vishal Zinjuvadia]

Hi,

I am trying to use a Tomcat webapp as a RMI client.
For the test purposes, my RMI server
resides on the same machine. When I use a Tomcat
webapp as a client, I consistently get a
ClassCastException, while if I use a plain java class
for the client, it works flawlessly.

Following is my client code used in the servlet and
the plain java class.

System.setProperty("java.rmi.server.codebase",
"file:/path/to/stubfile/");
try {
   //(line: 141)
   TestInterface testIf = (TestInterface)
Naming.lookup("//localhost/Test");
   result = testIf.testMethod();
} catch (Exception e) {
   servlet.log(e.getMessage());
   e.printStackTrace();
}

I am using:
JDK-1.4
tomcat-4.1.12

>From the stack it looks like the stub file is located,
but it cannot relate it
with the interface file.
