RE: Question - Form Validation

[Jacob Hookom]

Why not browse the Jakarta Validator libs?  They are integrated into
Struts.

Hi -

I was researching this very topic as an extension to using regular
expressions for form validation, and I found this on sourceforge.  It
might
be worth a look:

http://formproc.sourceforge.net/

I've never used it, but I plan to give it a look later.

Any web site references? I'm pressed for time so can't wait for item to
be
shipped and no local bookstores have it in stock...

Also, if I am to have my JSP form post back to itself to validate, I
would
need to employ Java Beans for this - is that correct?

Sorry - I'm a newbie :)

Thanks!

Re: Where can I find a complete mod_jk2 howto?

[Dave]

On Sun, 29 Dec 2002 01:01:54 -0500, you wroth:

I was, but just download mod_jk2 was not the end of the story,
there are a lot of .jar files I don't know where to download, 
there is why I start to compile it by myself.

I find there is a target named "compile.tomcat5" in /coyote/build.xml,
Does anyone know whether I can ignore it, because there is where the
bugs are.

Thanks
Dave

RE: SSL hangs on Tomcat 4.1.18

[mech]

I was just trying around with minProcessors="1" and maxProcessors="2"

Although I get this warnings quite easily (just 2 or 3 browser windows
are enough), after one request (really slow) is completed the next
request is processed. So obviously the threads must have been reused.
If I set acceptCount="1" the browser comes up with page not found if all
threads are in use.

Maybe play around with the acceptCount setting. Even If your load is
low, some "nervous" user might keep clicking on https links, if the page
is not loading quickly enough.
I wonder not to see an "connectionTimeout" attribut? I set to 2 for
http and https (default should be 6 according to documentation).
Maybe that makes a difference, too?

By the way I encountered the following exception, if I stress test too
much:

RE: Question - Form Validation

[Turner, John]

 
Thanks for the tip...didn't know anything about them.  I found that FormProc
package while investigating Jakarta Regexp.

As an aside, is there a need for Regexp or ORO now that J2SE 1.4 has
java.util.regex?  I'm no regexp guru by any means, I'm just curious.  My
development skills are bad enough without having to worry about keeping
track of packages/libraries that aren't part of J2SE/J2EE.

RE: Where can I find a complete mod_jk2 howto?

[Turner, John]

 
Let's take a step back.

You don't need to build any JAR files to use JK2 (or JK).  Support for both
is included in Tomcat 4 via the default CoyoteConnector.  Check server.xml.
Thus, with a binary install of Tomcat, you are all set.  If you are trying
to build everything from source (including Tomcat), let us know that.

The only thing you need "extra" for either JK or JK2 is the Apache module,
and binaries are available for both of them.  If you decide to build the
Apache modules for either JK or JK2, all you need to build is mod_jk.so or
mod_jk2.so for your appropriate Apache version.

I had lots of problems with ant trying to build things in the past couple of
months...I used to be a build-from-source-no-matter-what person, but that
stance has mellowed a bit for Tomcat-oriented tasks.  Grabbing the binaries
is much quicker.

Re: SSL hangs on Tomcat 4.1.18

I was just trying around with minProcessors="1" and maxProcessors="2"

Although I get this warnings quite easily (just 2 or 3 browser windows
are enough), after one request (really slow) is completed the next
request is processed. So obviously the threads must have been reused.
If I set acceptCount="1" the browser comes up with page not found if all
threads are in use.

Maybe play around with the acceptCount setting. Even If your load is
low, some "nervous" user might keep clicking on https links, if the page
is not loading quickly enough.
I wonder not to see an "connectionTimeout" attribut? I set to 2 for
http and https (default should be 6 according to documentation).
Maybe that makes a difference, too?

By the way I encountered the following exception, if I stress test too
much:


I don't know why you get that exception, but if you actually get it, 
then the root cause should be that something went bad during the socket 
accept.
Standard socket processing is obviously better tested than SSL sockets, 
so I doubt this happens; could you debug this further, and give more 
details ?

It would be a good idea to test stability with PureTLS or the newest 
JSSE (that might help if the problems come from JSSE from JDK 1.4).

I think I saw some error about sockets, too. But couldn't reproduce it
now. Maybe mixed it up. The only thing I can definitely reproduce as
often as I try is the above setting leading to those exceptions.

Actually this all was just a simple test myself. I didn't experience
problems with ssl under normal "setting". This thing with processors 1-2
was just a test I wouldn't do in real life.

My advice: Simply don't try those stupid settings. I wouldn't even know
where to start debugging more. I'm happy if everything works with the
default setup ;-)

I'm tracking down a problem which only occurs rarely, but has the 
symptom that when I attach
data to one session, it appears to mistakenly become attached to another

session. It is almost as if
tomcat is generating two sessions which have the same session id.

I'm looking at the tomcat source for createSession() in 
ManagerBase.java, and I notice this code is
commented out:

  }
  /*
  synchronized (sessions) {
  while (sessions.get(sessionId) != null)// Guarantee 
uniqueness
  sessionId = generateSessionId();
  }
  */
  session.setId(sessionId);


Does that mean tomcat could occasionally produce duplicate session id's?

Special character in file name

[Arcadius A.]

Hello!

I'm having a strange problem.

In my JSP, I have the following code :

 

My trouble is that the image doesn't show in tomcat  (see
http://ahouans.sh.cvut.cz:8080/test/test.jsp  ) ... but the image is on the
server (see  http://ahouans.sh.cvut.cz/test/test.jsp )

I have notced the following:

 The image does not display at all when the image name contains the
character  "+" and that the server is not accessed through port 80 (so the
trouble comes up Only when Tomcat is used in standalone mode... see
http://ahouans.sh.cvut.cz:8080/test/test.jsp [this is the standalone mode]
vs.  http://ahouans.sh.cvut.cz/test/test.jsp  [apache+tomcat] ...note that
we are accessing the same file through different ports )

I have the same problem with both tomcat 3.2 and 4.1.

Is there anything I am doing wrong?
Note that the files are uploaded on the server and I cannot tell the
people not to use special characters in their file name.

Thanks

Arcadius.

Re: Re: Is session id guaranteed to be unique?

[Glenn Olander]

Thanks. I installed my own Manager with a fix similar to yours and it 
seems to solve
the problem (I used a contrived Random class to generate duplicate 
session id's).

This certainly sounds like a serious bug to me. If there's a mechanism 
in place to
warn tomcat users about security problems, I'd recommend doing so, in 
addition
to applying the patch. Speaking of which, I may be wrong, but I don't 
think your
patch is quite right. You'll need to append the jvmRoute _before_ doing the
sessions.get() call, and again each time inside the loop. In other 
words, I believe
it should look like this:

   String sessionId = generateSessionId();
   String jvmRoute = getJvmRoute();
   // @todo Move appending of jvmRoute generateSessionId()???
   if (jvmRoute != null) {
   sessionId += '.' + jvmRoute;
   }
  
   synchronized (sessions) {
   while (sessions.get(sessionId) != null){// Guarantee 
uniqueness
   log("Found duplicate session id, getting a new one.");
   sessionId = generateSessionId();
   if (jvmRoute != null) {
   sessionId += '.' + jvmRoute;
   }
   }
   }
  
   session.setId(sessionId);

   return (session);

At a command prompt:

JAVA_HOME=/some/path/to/JDK; export JAVA_HOME

Test it at a command prompt:

  echo $JAVA_HOME

That will be valid for that login session only.  If you need it for every
login session, you'll want to put it in your login scripts.  If you want it
available for everyone, all the time, the best place to put that might be
/etc/profile. If you put it in scripts, put "export JAVA_HOME" on a separate

Please Help me

[Manoj Tyagi]

Hi,
I am new to this mailing list and Posting for the first time.
I have a prob. using Tomcat 4.0 on Win ME system with Apache 
My Apache is configured on port 80 properly and working fine.
I am Developing Sites in PHP and Its working fine with Apache.
 
Now I Installed Tomcat 4.0 on my system for JSP Support.
Tomcat is working fine seperately, When i use it on Port 8080

Now i want to invoke the JSP Support from Apache. 
I have been advised to Copy the ApacheModuleJserv.dll  in the Apache's Modules 
Directory and to include the following line in httpd.conf

LoadModule jserv_module modules/ApacheModuleJServ.dll 

I have done that.

I searched on net, and got that everytime Tomcat will generate the tomcat-apache.conf  
file in the conf directory of tomcat. It is advised to include the following line in 
the httpd.conf 

include "c:\tomcat\conf\tomcat-apache.conf"

My Tomcat is working fine, but there is no configuration file in the directory.


Please help me to come out with this prob.

Problems starting up...

[mia isabelle]

 
Hi,

I can't get the Tomcat server to start. I used the startup.bat, setclasspath.bat, 
catalina.bat with the following configuration:

Using CATALINA_BASE: d:\tomcat41

Using CATALINA_HOME: d:\tomcat41

Using CATALINA_TMPDIR: d:\tomcat41\temp

Using JAVA_HOME: D:\jdk1.3

When it executes the last line : %_EXECJAVA% %JAVA_OPTS% -Xdebug 
-Xrunjdwp:transport=dt_shmem,address=jdbconn,server=y,suspend=n 
-Djava.endorsed.dirs="%JAVA_ENDORSED_DIRS%" -classpath "%CLASSPATH%" 
-Dcatalina.base="%CATALINA_BASE%" -Dcatalina.home="%CATALINA_HOME%" 
-Djava.io.tmpdir="%CATALINA_TMPDIR%" %MAINCLASS% %ACTION%

I got the followings:

at java.lang.Class.newInstance0(Native Method)

Can someone point out where I could get the "org/xml/sax/InputSource"?

I wanted to test out Tomcat 5.0 alpha but I can't find any links on the
Jakarta Tomcat website anywhere where I can download a 5.0 build.  Is
this a secret or what?

Re: Tomcat log entries

[Bill Barker]

This is simply some Windows server that is infected with the Nimbda Worm
looking for a new place to crawl to.  It only infects non-patched IIS
servers, so for Tomcat stand-alone or Apache, you can safely ignore it.

Re: Please Help me

JServ is deprecated, and AFAIK, not supported at all for Tomcat 4.x.  Since
you are running under Windows, mod_webapp isn't an option.  You'll need to
get the mod_jk connector from
http://jakarta.apache.org/builds/jakarta-tomcat-connectors/jk/release/v1.2.2
/.

Hi,
I am new to this mailing list and Posting for the first time.
I have a prob. using Tomcat 4.0 on Win ME system with Apache
My Apache is configured on port 80 properly and working fine.
I am Developing Sites in PHP and Its working fine with Apache.

Now I Installed Tomcat 4.0 on my system for JSP Support.
Tomcat is working fine seperately, When i use it on Port 8080

Now i want to invoke the JSP Support from Apache.
I have been advised to Copy the ApacheModuleJserv.dll  in the Apache's
Modules Directory and to include the following line in httpd.conf

LoadModule jserv_module modules/ApacheModuleJServ.dll

I have done that.

I searched on net, and got that everytime Tomcat will generate the
tomcat-apache.conf  file in the conf directory of tomcat. It is advised to
include the following line in the httpd.conf

include "c:\tomcat\conf\tomcat-apache.conf"

My Tomcat is working fine, but there is no configuration file in the
directory.


Please help me to come out with this prob.

Regards


Manoj Tyagi

It should be in the xerces jars, which should be living in

set to.

If you find which of these isn't true on your system, you've probably solved

Re: Where can I find a complete mod_jk2 howto?

[Bill Barker]

Building from source really isn't that bad.  Granted, I haven't managed to
get the Ant build to work for Jk2, but if you're GNU tools are sufficiently
up-to-date (e.g. Make, AutoConfig, LibTool), then using 'buildconf.sh' and
'configure' is reasonably painless to build the mod_jk2 native code.  The
mod_jk module (aka 'native') is more forgiving of older versions of the GNU
stuff.

RE: Where can I find a complete mod_jk2 howto?

[Turner, John]

 
Well, I hope you're around next week when I get back to my desk.  ;)

I tried building JK from the 1.2.2 source before I left for the holidays and
had zero result.  Everything ran beautifully, no error messages that I could
see either on the screen or in the configure log, yet after running 'make'
and 'make install' I didn't have a mod_jk.so file anywhere on my system.  It
was very perplexing!

RE: Servlet/Session/Attribute Listeners not very useful ?

[Mohan Radhakrishnan]

Hi,
   We implement session timeout by writing a filter.

   We have a requirement to put user configurable reports into the session.
Now if the user object ( a small container with a profile ) in the session
is bound we need to load previously configured reports into the session.

   They seem to be quite useful from the business logic perspective. We too
get exceptions but my filter should block the app. before these happen.

Subject: Servlet/Session/Attribute Listeners not very useful ?


Hi all,

Can anybody tell me what possible use these particular interfaces
are ?

After thinking that they would be a good idea to use for web app
session management enhancements (session timeout etc) it turns out
that the invocations of valueUnbound(), sessionDestroyed(),
attributeRemoved() all occur _after_ the event has occurred, and
the values that would possibly be useful are all gone throwning
IllegalStateExceptions left right and centre.

What gives ? Did the Servlet Spec people have some other use for
these Interfaces that I'm not smart enough to work out, or are
they only useful for printing "object added|removed|replaced"
without being able to actually obtain the object?

The specifications for 2.4 for javax.servlet.http.HttpSession
still say the same things as 2.3, and if implemented in the
same way don't appear to be useful at all

Or is there some special magic that I'm not invoking the right
way ?

Help me, I'm confused ..

Cheers,

RE: Struts - XML/XSL

[Schnitzer, Jeff]

Take a look at the Maverick MVC framework (http://mav.sourceforge.net).  It is 
Struts-like in concept, but you can run any model through an arbitrary pipeline of 
XSLT (and several other) transformations in Cocoon-like fashion.  The pipeline will be 
efficiently connected with SAX events if appropriate.  As an example, you can easily 
run your model through an XSLT transformation and then through a FOP transformation to 
send PDF back to the client.

Using the optional Domify module, you don't even need JSP to generate the XML in the 
first place.  The Domify adapter uses reflection to create a lazily-loaded DOM façade 
of your model directly.  This is much more efficient than generating and parsing text 
XML.

Try it out :-)

RE: Servlet/Session/Attribute Listeners not very useful ?

[Jason Jonas - ATTBI]

Jon,

I've used the SessionListener interface once to write usage stats to a
database when a user logs out explicitly or implicitly when the
session times out. Haven't used it since and not too sure if I would
again. However, the mechanism worked well enough to satisfy our
requirement.

If you're trying to access your application objects bound into the
session, perhaps you could wrap them in a single application object.
While this is a kludge, it means the object references are readily
available and would eliminate the IllegalStateExceptions you're
encountering now. Just a thought.

Subject: Servlet/Session/Attribute Listeners not very useful ?

Hi all,

Can anybody tell me what possible use these particular interfaces
are ?

After thinking that they would be a good idea to use for web app
session management enhancements (session timeout etc) it turns out
that the invocations of valueUnbound(), sessionDestroyed(),
attributeRemoved() all occur _after_ the event has occurred, and
the values that would possibly be useful are all gone throwning
IllegalStateExceptions left right and centre.

What gives ? Did the Servlet Spec people have some other use for
these Interfaces that I'm not smart enough to work out, or are
they only useful for printing "object added|removed|replaced"
without being able to actually obtain the object?

The specifications for 2.4 for javax.servlet.http.HttpSession
still say the same things as 2.3, and if implemented in the
same way don't appear to be useful at all

Or is there some special magic that I'm not invoking the right
way ?

Help me, I'm confused ..

Cheers,

Yeah. That is also a use. Again, it's "anonymous" in that you can't
identify exactly what session expired, just that a session expired.

session, perhaps you could wrap them in a single application object.
While this is a kludge, it means the object references are readily
available and would eliminate the IllegalStateExceptions you're

It's more that I want to "clean up" some application wide data
when the session expires. I can't even work out how to map the
session that has just expired to anything useful either. If I
could get the "session id of the session that expired" then it
could store the information in application scope and use the ID
as a key.

From my reading of the Servlet Specs and the API documentation it
appears that the intention of the expert group was along those
lines, but it doesn't seem to have carried through in the
implementation.

"SRV.10.7 Session Events
Listener classes provide the developer with a way of tracking sessions
within a web application. ... session became invalid because the
container timed out the session, or because a web component .. called
the invalidate() method. The disctinction may be determined indirectly
using listeners and the HTTPSession API methods"

and

javax.servlet.http.HttpSessionListener

public void sessionDestroyed(HttpSessionEvent se)

Notification that a session was invalidated.

javax.servlet.http.HttpSessionEvent only has 1 method, to get the
session. Which at that time is invalid.

I might have to try some more obscure options like trying to use
an HttpSessionAttributeListener and the HttpSessionBindingEvent to
see if when a session is invalidated a BindingEvent is emitted.
I'm not thinking I'm going to be all that successful though.

I was half hoping that Craig might be able clarify after he's finished
with his Festive cheer ;-)

Cheers,
	-- jon

Where can we find Tim's patch (post the patch to the list please).

two reasons for this:
to implement it
and to peer review it.

IMHO, the source should be patched.  As a result, Tim's patch will be in the
4.1.19 release.

Mysql driver problem...

[Keith Pemberton]

Ok, first off sorry if this is a little vague and I can write more
details later.  Anyway, I am new at this stuff with setting up the mysql
driver to work with tomcat by setting a JNDI Datasource.  I followed the
directions under that heading in the documentation from the Tomcat
website for the mysql driver, but I keep getting a "Cannot load JDBC
driver class 'null'" message when I try to create a connection using the
driver.  I put the .jar file in the $TOMCAT/common/lib directory and
restarted tomcat.  Anyone have any quick tips for me to try?  I can post
my code later if yall need it; it's just late right now and I don't feel
like cutting and pasting.  Anyway, thanks in advance!

Keith

session id's really unique?

[shawn]

If I use RequestDispatcher.forward(request, response) to another context
am I running the risk of session id conflicts?  

I mean if a session Id is given in one context, another context is
restarted and the java.security.SecureRandom is re-initialized for that
webapp, then it would seem possible that newly generated sessions in the
second context could match the previosly generated session id that was
transferred from the first context.

I doubt I know as much as many on this list, but that is something that
I wondered about.

Shawn

PS  I'm relying on potentially outdated info from a list that was posted
in response to this topic.

 yes I did but will the sessions tranfer uniquely?
