Hi all :)

My form submits to a controller jsp which uses a bean to check validation.
If info is validated, the controller forwards to a verify page, else forward
to a retry page with appropriate error messages.  After some tweaking this
all worked perfectly.

After realizing that the first JSP I called (i.e. FormValidate.jsp) shows in
the URL even after control is forwarded to another jsp, I wanted to change
the name of the file.  I changed FormValidate.jsp to CCProcess.jsp, and
changed all the appropriate action tags to call CCProcess.jsp.  Now I can't
get to Verify.jsp.  Even when all info on form is correct it is still
calling Retry.jsp and I get stuck in a never ending loop in Retry.jsp - even
though there are no error messages...

Could changing the file name be the cause of this?  Its as thought the if
(formBean.validate) always fails... but I don't think the problem is my
bean, as I mentioned it worked perfectly before...

Thanks.
Denise

Vincent,

Not sure which connector you are looking to use, but go here:

http://jakarta.apache.org/builds/jakarta-tomcat-connectors/

I checked and you'll find the binaries for linux for the latest version of
mod_jk, and v2.0.1 of mod_jk2.

Need help w. viewing Servlet!!

2003-01-05 Thread Steve R. Burrus

  Hello everyone, I need some help/assistance with trying to see a Servlet in my 
Tomcat v. 4.1.16!!! It is a simple log on page with a text box for the user's name and 
also for the email addrr. When I click on the Submit button after filling in both 
fields, the next page indicates a damn server error, i.e., HTTP Server Errror 404, 
indicating that the requested resource was not found by the server!!! 

 I think that it is saying that the required class bearing the particular name was not 
found, for some reason!! I have gone into the web.xml file to do some heavy [sic] 
editing of it, such as putting in the servlet name and the servlet class, but alas, to 
no avail so far! It is driving me absolutely crazy that I cannot seem to even be 
able to view this rather simple servlet. Then again, maybe it shouldn't, in that I am 
admittedly the very newest of the Newbies out there first trying to get involved 
with creating these components of the J2EE API like Servlets and Java Server Pages. 
And I will cut off anyone who suggests a good book on the J2EE to me because I 
really am NOT looking for a book to read to help me out with this problem. NO, I am 
looking for some hard and useful advice from someone. Capiche?

Tomcat-SSL: no cipher suites in common Exception

2003-01-05 Thread Dor Perl


Hi All, 

Our site is running on Tomcat 3.3/Windows2k stand alone and we want to create a 
secured page on the Tomcat server (can be a different machine). 
We bought an SSL certificate from Comodo (after sending them our CSR that was 
created using keytool) afterwards we imported the received certificate to the 
keystore. 
The server starts ok, but when a web browser access it on the SSL port, we get the 
following exception:

* generated my own certificate using keytool (and it works ok. But the certificate is, 
of course, invalid) 
* Tried to access the server with different SSL protocols. 
* Searched every possible thing in the net ;-( 
I dedicated alot of time for this thing but no good. I would be grateful if somenoe 
could help us. Is it possible that the problem is in the certificate we got from the 
SSL provider? 

Thanks in advance for your help,

No, I don't really have any reservations about JDOM...except for

that there has been little to zero development on it of

the amount of time that has passed since the last beta release

years while Xerces development steams on ahead.  JDOM may be 
elegant, but I
wish the main developers would put their nose to the grindstone 
and get, at
least, another beta release out in short order!

To tell you the truth, I would just use a SAX parser.  That will 
be faster
than any of the other methods including JDOM.

 //now do something with the node
}
catch (XPathSyntaxException xse) {}
catch (JaxenException je) {}


If you know, in advance, all the elements you will need to 
read, then
you might want to write a SAX parser for your document.  It 
will be
the fastest methodor you could use XML data binding using 
Zeus or
JAXB which will allow you to read in a whole document and 
access all
the data using standard Java Bean getters and set the values using
standard Java bean setters.  In this case, you don't even need to
worry about XML since the fact that it is XML is totally

you.  You can then marshal your updated object (assuming you 
modified
it) back to an XML document.

There are lots of ways to do this.  Which way you choose

RE: Changed file name now webapp not working right

Denise,

The front end is/was FormValidate.jsp/CCProcess.jsp, which forwards to
Verify.jsp or Retry.jsp?

You renamed it, and now when you submit the form you never get to
Verify.jsp?  You are saying that when Retry.jsp submits the form, the form
action is CCProcess.jsp?  Have you put any log code into CCProcess.jsp to
trace what is happening?

RE: Tomcat and Apache


If you have an Apache VirtualHost of www.admged.ufu.br, you must have a Host
in server.xml with the same value.

If you have a JkMount line that says JkMount /test/* ajp13 you must have a
Context named /test in server.xml for the host www.admged.ufu.br.

The best examples are the files that come with Tomcat itself, meaning
server.xml and the Tomcat examples, which are /examples.

For example, in a default installation, there would be something like this
in httpd.conf:

VirtualHost localhost

JkMount /examples/*.jsp ajp13

/VirtualHost

And in server.xml:

Host name=localhost

Context path=/examples docBase=examples debug=0
 reloadable=true crossContext=true

  !--- some other stuff here ---
/Context

  !--- some other stuff here ---

/Host

This will send requests for http://localhost/examples/*.jsp to the /examples
Context of Tomcat.

I have HOWTOs on my site that explain exactly how to link Apache and Tomcat
together to serve the Tomcat examples through Apache on port 80, for Red
Hat, Solaris, and Windows XP.  After that, the rest is up to you, as only
you have the configuration that you have (virtual hosts, etc).  In your
case, you would simply duplicate what is in server.xml for the localhost
virtual host and change localhost to www.admged.ufu.br, then add your
Context for the webapp.  If you want your webapp to be in /* instead of
/myApp/* then you would put your web application in Tomcat's special ROOT
Context, an example of which is also in server.xml.  

The HOWTOs are here: http://www.johnturner.com/howto and there are many
others on the net.

The configuration of the virtual host in the Apache is striped below, in

ServerName admged.ufu.br

/VirtualHost

Since then they follow my questions, I have faith that even certain point,
very basic:  

1 - I have the configuration of the virtual host www.admged.ufu.br in the
Apache. Is it necessary to do the configuration of the virtual host
www.admged.ufu.br in the file of configuration of Tomcat, and will I use the
two (Apache + Tomcat) in an integrated way?

2 - Below it is the listing of my tree of directories that will store the
test pages. I want that all my files jsp under / web/admged are interpreted
as files jsp by the server. Like this being, as it should be my JKMount in
the Apache?

admged@admged:~  tree /web/
/web/

|   `-- classes
`-- admged
|-- WEB-INF
|   `-- classes
|-- index.jsp
`-- log

`-- apache_error_log

6 directories, 3 files

If they could send in some way some example file or a documentation that it
shows in a clear way as proceeding with the configuration I will be very
thankful. I thank the released help once again.

RE: Need help w. viewing Servlet!!


Steve -

Sorry, but I have been reading your rants on this list for months.  Many
people have tried to help you, over and over and over, yet you still have an
attitude.

I suggest you get yourself a book, take a deep breath, and stop ranting.
You will get a LOT MORE help from the people on this list if you chill out
and ask nicely instead of posting with an attitude.

Cut me off if you like, but realize, if you can, that the very people you
are cutting off are the very people who can help you, and the advice they
are giving you is the advice you should take.  For example, GETTING A BOOK
AND READING IT, or perhaps, heaven forbid, READING THE DOCUMENTATION.

Since you will probably ignore that advice, you will probably ignore this
advice as well, to your detriment and continued frustration:  if you want
help from the list, follow the examples that nearly everyone else follows,
and post with VERY SPECIFIC information.  Posting with I did heavy editing
of web.xml and Help me now I get a 404 will just get you ignored, when
posting a specific question, saying please, and including the relevant JSP
or servlet that you are using in your post will almost GUARANTEE you a fast
answer, allowing you to quickly relieve your frustration.

I posted a HOWTO for Apache + Tomcat + mod_jk on Windows XP on my site.  If
I recall correctly, you are using Windows XP.  If, in the future, you wish
to try integrating Apache with Tomcat again using mod_jk, perhaps my HOWTO
will help you and you won't need to post another rant here to the list.

The choice, I guess, is up to you.  Have a great new year.

Subject: Need help w. viewing Servlet!!


  Hello everyone, I need some help/assistance with trying to see a Servlet
in my Tomcat v. 4.1.16!!! It is a simple log on page with a text box for the
user's name and also for the email addrr. When I click on the Submit button
after filling in both fields, the next page indicates a damn server error,
i.e., HTTP Server Errror 404, indicating that the requested resource was not
found by the server!!! 

 I think that it is saying that the required class bearing the particular
name was not found, for some reason!! I have gone into the web.xml file to
do some heavy [sic] editing of it, such as putting in the servlet name and
the servlet class, but alas, to no avail so far! It is driving me absolutely
crazy that I cannot seem to even be able to view this rather simple
servlet. Then again, maybe it shouldn't, in that I am admittedly the very
newest of the Newbies out there first trying to get involved with creating
these components of the J2EE API like Servlets and Java Server Pages. And I
will cut off anyone who suggests a good book on the J2EE to me because I
really am NOT looking for a book to read to help me out with this problem.
NO, I am looking for some hard and useful advice from someone. Capiche?

RE: need help w. viewing servlet


Please post the JSP code that is creating your form, and describe where your
servlet is located that you wish to receive the form submission.

Generic comments like it doesn't work will most likely get you ignored by
the list, especially considering your past history here.

Also, you might want to include the heavy editing you did in web.xml, that
is, post it here so that we can see what you did.  We aren't mind readers.

Have a great day.

John

RE: need help w. viewing servlet

 I have gone into the web.xml file to do some heavy [sic] editing
 of it, such as putting in the servlet name and the servlet class,
 but alas, to no avail so far!

Well, it would help to see that segment of the file, and also find out from
you where you put the .class file.  Do you have a servlet mapping defined,
or just the servlet?  If the latter, did you enable the invoker, or are you
just sort of waiting for magic to happen?

In other words, in addition to (for example):

  servlet
servlet-name
   photo
/servlet-name
servlet-class
   com.devtech.servlet.PhotoServlet
/servlet-class
  /servlet

you also need

  servlet-mapping
  servlet-nameinvoker/servlet-name
  url-pattern/servlets/*/url-pattern
  /servlet-mapping

or an explicit mapping for each servlet.

 Hello John, I will wisely ignore all of the damned admonitions that you saw fit
to sort of dish out to me (stuff that you have certainly said to me
before!)and acknowledge your Happy New Year wish you ended your email msg. on! 

 Listen, there IS one, and just one criticsm of me that I will go along with, and
that is that I just flat don't give enough detail of what the problem is exactly
to everyone else in our newsgroup!! That's why I am including in this email
message the html page that is the servlet in question, which as I have said
before, is nothing but a logon page with 2 textboxes. One is for the user's name,
and the other one is for the user's email address. I am quite sorry that I was not
allowed/permitted to save the server error [the 404 server error] page for some
reason. And I will try to include the so-called heavy editing that I mentioned
in my first post of the web.xml file in a later posting to our little newsgroup
because I really don't believe, in my subjective opinion, that it's all that
important, to be frank and honest (which I am always am :) ). I mean, the little
bit of editing of it that I have done with other JSP's/servlets in the past has
not yielded any successful results at all.

iPlanet 6.0/Solaris 8: nsapi_redirector.so symbol errors

2003-01-05 Thread Brian_Carmody


I am trying to get an iPlanet 6.0 web server to talk to a tomcat 4.1.18
apps server.  What i've read so far is that i need an nsapi plugin
nsapi_redirector.so to redirect the appropriate requests down to the apps
server. I downloaded the 4.1.18-connector source, and found
jk/native/netscape undernearth. defining SUITEPOT_HOME to the iplanet
install lets me make without any errors in that directory. After modifiying
obj.conf and magnus.conf and restarting,  the iPlanet instance dies and in
the $SUITESPOT_HOME/$INSTANCE/logs/errors, i see:

[05/Jan/2003:15:47:42] info (28713): iPlanet-WebServer-Enterprise/6.0SP2
B11/13/2001 00:49

Any ideas on why nsapi_redirector.so is failing?  Is this even the right
way to get iPlanet to talk to tomcat?

Look at it this way: since your servlets aren't working, it makes sense to
provide the information that people whose servlets are working do believe to
be useful.

Re: can tomcat do dynamic virtual hosts?

2003-01-05 Thread Joseph Shraibman

Turner, John wrote:

Tomcat has an Alias element in server.xml. It goes under Host.

OK thanks for pointing that out.

Tomcat needs to do what it needs to do because a web app is

more than just a

directory that has content in it.

Right, but sometimes you might want to lump multiple things into one
webapp.

Sorry, I have no idea what that means.

Somtimes you want a.host.com and b.host.com to be in the same webapp

Which is my point. Using auto-deply is not the same thing as simply
creating a directory and putting files in it. Apache has the dynamic
virtual host feature for a reason. Using auto-deply requires
that all
your content be under directories, which doesn't look as nice
as having a
hostname. name.host.com is better than host.com/name

You can have name.host.com. I just don't understand why you think you can't
do that. Tomcat's Host element can take ANYTHING as its name parameter
(within reason) and the Host element can take an Alias element.

Nowhere in Tomcat is a rule that says host.com/name is the only legal URL.
You can have name.host.com all you like, you just configure Host
accordingly and put the webapp in the special ROOT Context and your webapp
is served as name.host.com/. How is that not what you want?

My point is that a webapp is not just a directory with some files in it.
There's a lot more to a webapp then that, and thus, there is more that
Tomcat has to do and more configuration overhead required or possible
(Realms, etc). You can auto-deploy a Context.

How? If I want to add a new Context don't I have to restart tomcat to reread the
server.xml file.

Scroll down to the section that says automatic application deployment and
the following section on host name aliases. Basically, for a dynamic
virtual host, since you're going to need a restart anyway (see Craig's
comments on possible future ability to pick up config changes on-the-fly
without a restart):

That's my point. In apache it doesn't need a restart.

- add a new Host element to server.xml with one or more Alias
- drop an XML file into the appBase directory, according to the auto deploy
specs to auto-define your web app

Since you have a restart, a new mod_jk.conf file is generated, and it will
have the new Host information in it.

I gave up on autogeneration.

Even so, you wouldn't WANT a restart, because having a monolithic Tomcat
with many many virtual hosts and webapps in it is the wrong way to go in an
ISP/ASP scenario (in my opinion).

This isn't that scenario, but we do have multiple webapps and hosts.

So, if you agree with that, then what

you're really talking about is a small shell script that simply copies the
default server.xml to server-customer-account.xml, creates a
work-customer-account directory, and does all of the other things required
to have a distinct instance of Tomcat running (including the Host and web
app config listed above), and then does a start on the new Tomcat.

Distinct tomcat? That would mean a different port for each tomcat, plus the overhead (90
megs of memory on my test machine)

Maybe I'm just a tree stump, but I haven't seen you propose a case that
can't be handled.

The case where tomcat works with my Apache dynamic virtual hosts. Apache doesn't *need*
dynamic virtual hosts either, you could just use a lost of virtual hosts. It would be nice
if tomcat supported the same thing.

RequestDispatcher and forward

2003-01-05 Thread jejonas

OS: Windows XP - for development
TC: 4.1.18
JA: 1.4.1_01

I was under the impression that after calling RequestDispatcher.forward the 
method would return and all subsequent processing would cease. However, this 
apparently isn't the case. 

For instance, when a user logs on successfully, we attach an object to the 
user's session and forward to the last known uri, but if the login failed, we 
forward the request back to the login page with invalid fields attached to the 
request. The logic kinda goes like:

if successful login {
  attach user info to session
  forward to last known uri
}
attach invalid fields to request
forward to login page

The behavior we're seeing is that the 'forward to login page' fails with an 
IllegalStateException (Cannot forward after response has been committed).

So what's up? Are we wrong to assume that a method effectively 'returns' after 
a forward and we need to add return statements after forwards or is there 
something we're missing altogether? 

Thanks.

Jason

 Is there a possibility to replace some Tomcat jars with jars from J2EE?

I got this exception when I invoked the getWriter() or when I set the 
content-type before doing the forward.

So what's up? Are we wrong to assume that a method effectively 
'returns' after
a forward and we need to add return statements after forwards or is 
there
something we're missing altogether?
Don't know if I understand you, but I see no way in java for a method 
to cause the invoking method to return immediately.

Re: mod_jk: Disable sticky sessions

2003-01-05 Thread Tim Funk

In server.xml:
Set cookies=false for your application context.
Eg: (Taken from sample config from 4.1.18)
Context className=org.apache.catalina.core.StandardContext 
crossContext=true reloadable=false 
mapperClass=org.apache.catalina.core.StandardContextMapper 
useNaming=true debug=0 swallowOutput=false privileged=false 
wrapperClass=org.apache.catalina.core.StandardWrapper 
docBase=examples cookies=false path=/examples 
cachingAllowed=true 
charsetMapperClass=org.apache.catalina.util.CharsetMapper

This should turn cookies off for sessions. If you do not URL encode your 
sessions - then there will be no way for users to be sticky.

The bad part is - every request will allocate a new HttpSession. (If 
request.getSession(true) is used or every JSP does not contain the 
command to not not create a session. )

-Tim

Hello,

I would like to use mod_jk as simple loadbalancer without sticky sessions.

Is there any way to disable sticky sessions in mod_jk?

I don't have jvmRoute atribute set but sessions are always sticky.

I'm using
mod_jk-1.3-eapi.so
apache 1.3.26
jboss-3.0.4_tomcat-4.1.12

Thanks a lot for any hint

RE: need help w. viewing servlet

 Okay Noel, this posting of mine this time is for you. You said earlier that you
didn't get the servlet page html file. Well, here it is again, and also it let me
save the server error [html server 404] page for the GreetingServlet.java
program, so I present that to you also!

 Listen, would you please, please go into more about editing the web.xml file??? i
really am just a damned novice when it comes to trying to edit this file! And, I
also take back my earlier pronouncement that this file wasn't really too
important. Nothing can possibly be further away from the truth, I have come to
realize. It is the very controlling file that gets either the Servlet or the Java
Server Page to function or operate properly, at least while trying to use tomcat
to see the JSP/Servlet. Would you kindly tell me a lot more about the
servlet-mapping tag and how it should be used to its' full potential to see a
servlet in my web browser. Yes, I will eat a lot of humble pie in backing down
from my previous position that this file wasn't important. I am appealing to you
now, Noel, because you seem to be such an expert on these matters. :)

RE: can tomcat do dynamic virtual hosts?

-Original Message-
From: Joseph Shraibman [mailto:[EMAIL PROTECTED]] 
Sent: Sunday, January 05, 2003 3:58 PM
To: Tomcat Users List
Subject: Re: can tomcat do dynamic virtual hosts?

 Sorry, I have no idea what that means.

 Somtimes you want a.host.com and b.host.com to be in the same webapp

That's what Alias is for.

 that Tomcat has to do and more configuration overhead required or 
 possible (Realms, etc).  You can auto-deploy a Context.

 How?  If I want to add a new Context don't I have to restart tomcat to
reread the 
 server.xml file.

Yes, this has already been discussed in this thread.  Craig pointed out that
picking up config changes without restarts is something being discussed for
Tomcat 5.  Perhaps, if it is that vital to you, you might want to subscribe
to tomcat-dev and get in on the discussion to voice your views.

 restart anyway (see Craig's comments on possible future ability to 
 pick up config changes on-the-fly without a restart):

 That's my point. In apache it doesn't need a restart.

I have no idea what you mean.  Apache most certainly does need a restart to
pickup changes in httpd.conf.  You either use restart or graceful for it
to get changes.  Yes, it's not a full stop and a full start, but even with
restart and graceful, any current connections are either cut off
prematurely (restart) or allowed to finish (graceful) before httpd.conf is
reread.

 Since you have a restart, a new mod_jk.conf file is generated, and it 
 will have the new Host information in it.

 I gave up on autogeneration.

OK...I'm not really sure what that has to do with anything.  An Apache
restart is required whether you use auto-generation of JK configuration or
not, since using JK requires changes to httpd.conf (see my comments above).

 Host and web app config listed above), and then does a start on the 
 new Tomcat.

 Distinct tomcat? That would mean a different port for each tomcat, plus
the overhead (90 
 megs of memory on my test machine)

Well, this has been discussed before on the list.  In my opinion, using an
extra port and some more RAM is well worth the extra advantages you get in
administration.  You might want to rethink the scenario...you're going to
run out of RAM and CPU long before you run out of ports, and being low on
RAM is a very easy (and cheap) problem to solve.  I'm currently running 22
Tomcats, from low traffic to high traffic, on one of my servers. Granted, I
didn't design the original setup, but after many months of analyzing the
efforts of those who did, and building on it, I'm convinced it was the right
way to go and I won't be doing it any differently in the future.  There are
zero user complaints, and as the administrator it's a piece of cake to work
with one Tomcat (or create new ones or delete old ones) without affecting
anyone else. One web application hang doesn't touch anyone else, for
example.  In an ISP/ASP scenario, I would think that's exactly the type of
behavior you would want, but maybe I'm wrong.  

Are you planning to resell Tomcat somehow?  If I was your customer, and you
told me my app was down because somebody else's webapp was causing problems,
I wouldn't be a customer for long.

Basically, it sounds like you want everything to magically happen by putting
a couple wildcard statements somewhere.  Don't you think that's an
unreasonable expectation?  If you're selling Tomcat hosting, it's piece of
cake to justify the extra expense in managing it to your customers.  I've
only seen one hoster offering Tomcat 4 for less than $40/month/account.

 Maybe I'm just a tree stump, but I haven't seen you propose a case 
 that can't be handled.

 The case where tomcat works with my Apache dynamic virtual hosts. Apache
doesn't *need* 
 dynamic virtual hosts either, you could just use a lost of virtual hosts.
It would be nice 
 if tomcat supported the same thing.

Well, then I suggest you bust out some code to make it do that.  I don't see
any need for it in Tomcat, and it looks like the dev team doesn't either.
Perhaps they need to hear your point of view.  In my mind, Tomcat is a
deluxe service, not a throwaway service like Tripod or Geocities or
whatever...justifying the increase in cost, assuming that you plan to resell
the service, is a pretty easy thing to do.  

As I said before, it's a pretty trivial matter to write a script that will
setup virtual hosting with Tomcat just about as easily as you can do it, and
so far the only downside is using an extra port or two and using some RAM.
I don't think those are downsides at all given the tradeoff.

RE: need help w. viewing servlet


Expect even more frustration, then, Steve, instead of progress and success.

How to map servlets in web.xml is a topic that comes up just about daily on
this list.  It's also a topic that is covered extensively, with examples, in
the Tomcat documentation available on the Jakarta site.  It's also a topic
that is covered extensively in all of the many Tomcat and JSP/Servlet books
that are currently on the market.

With a little initiative, you could have answered your own question by now
using the documentation available on the web for free, or with a book.
Instead, you're going around in circles, ranting at the very people you're
asking for help.  That makes a lot of sense.

It's your choice how quickly you want to progress learning this technology.

 Listen, there IS one, and just one criticsm of me that I will go along

problem is exactly to everyone else in our newsgroup!! That's why I am
including in this email message the html page that is the servlet in
question, which as I have said before, is nothing but a logon page with 2
textboxes. One is for the user's name, and the other one is for the user's
email address. I am quite sorry that I was not allowed/permitted to save the
server error [the 404 server error] page for some reason. And I will try to
include the so-called heavy editing that I mentioned in my first post of
the web.xml file in a later posting to our little newsgroup because I really
don't believe, in my subjective opinion, that it's all that important, to be
frank and honest (which I am always am :) ). I mean, the little bit of
editing of it that I have done with other JSP's/servlets in the past has
not yielded any successful results at all.

With Yahoo! Mail you can get a bigger mailbox -- choose a size that fits your needs

When you use keytool to generate the keys and CSR, you should use the 
algoritm RSA  ,   not the default DSA. and then the exception will dispear.

RE: Changed file name now webapp not working right

Noel,

I even tried changing everything back to FormValidate.jsp and it still
doesn't work...

Yes, your scenario is correct, form action was FormValidate.jsp - and is
now CCProcess.jsp, and depending on outcome of form validation,
CCPRocess.jsp will forward to Verify.jsp or Retry.jsp.  But now after the
rename I never get to Verify.jsp.  The action of Retry.jsp is
CCProcess.jsp.  What is completely boggling my mind is that it was working
perfectly before I changed the file name :( Well I guess its true what they
say, if its not broke...

And I feel pretty dumb saying this, but I do not know how to trace using log
code. I am assuming you mean add some code in the jsp file (and/or
FormBean.java?) that will write to a log file to see what is happening.
Would you be able to recommend the code and the placement of that code so I
can trace this? Or maybe point me in the right direction to some
documentation?

Thanks :)

You renamed it, and now when you submit the form you never get to
Verify.jsp?  You are saying that when Retry.jsp submits the form, the

Tomcat-4-1-12 Connection Pool problem JNDI Datasource

RE: need help w. viewing servlet

Steven,

As you can see from the link below, there were no HTML attachments of any
kind to your message.  And what I think we really need is your web.xml file.

http://nagoya.apache.org/eyebrowse/ReadMsg?[EMAIL PROTECTED]
he.orgmsgNo=97097

The web.xml file is described in detail in the Servlet specification.
Tomcat provides web.xml examples, including
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/appdev/web.xml.txt.  Note
the servlet-mapping elements, which follow immediately after the servlet
elements.  You need to provide a servlet-mapping for each servlet, unless
you define the invoker servlet as I did in an earlier message.

In your case, if you have a servlet named GreetingServlet in a package
org.burrus, then you would place GreetingServlet.class in
WEB-INF/classes/org/burrus/GreetingServlet.class, and you would place the
following in web.xml:

  servlet
servlet-name
   GreetingServlet
/servlet-name
servlet-class
   org.burrus.GreetingServlet
/servlet-class
  /servlet

  servlet-mapping
  servlet-nameGreetingServlet/servlet-name
  url-pattern/greeting/url-pattern
  /servlet-mapping

At which point /greeting should result in GreetingServlet being invoked.

yet. Dom4j's web site does offer some links to benchmarks:
 
http://www.dom4j.org/benchmarks/xpath/index.html  Dom4j vs. Xalan with XPath Queries
http://www-106.ibm.com/developerworks/library/x-injava2/  Dom4j vs. Everyone
 
Dom4j also has support for PullParsing or XPP.  This, when paired with the ability to 
prune on read allows very large documents to be executed upon in short order. One 
other issue is that Dom4j does not align with the w3c standard API.  There are 
partially finished classes for integration, but it needs some work yet as of the last 
release I looked at (1mo).
 
If we want to discuss XML-Bean-XML, then yes, Betwixt would be ideal.  I prefer 
Castor (www.castor.org) because it provides a little more customizability for how the 
documents are (un?)marshalled.

Hi Jacob,

Did you actually test the performance of Dom4j?  I'm just curious.  I have
heard very good things about Dom4j.

 No, I don't really have any reservations about JDOM...except for
 the fact
 that there has been little to zero development on it of
 late.  Check out
 the amount of time that has passed since the last beta release (9
 - 10
 months!).  At this rate, they'll release a 1.0 version in a
 couple more
 years while Xerces development steams on ahead.  JDOM may be
 elegant, but I
 wish the main developers would put their nose to the grindstone
 and get, at
 least, another beta release out in short order!

 To tell you the truth, I would just use a SAX parser.  That will
 be faster
 than any of the other methods including JDOM.

 Howdy,
 
 Thanks for all the good suggestions. I'm going with JDOM, just
 because
 it's pretty darn elegant and simple. It also appears that it will be
 (if not already) an XML standard for Java.  So all signs
 indicate that
 I'm not marrying myself to an obscure API.
 
 Do any of you have reservations about JDOM?

 Well,
 
 There are a number of parsers available.  You can use DOM, JDOM,
 DOM4J, SAX, or, actually, you might want to try out XPath using
 Jaxen.
 
 Here is an example of reading in a document using DOMand no
 specific external package so you don't marry yourself to a
 particular
 implementation...
 
 DocumentBuilderFactory dbfactory =
 DocumentBuilderFactory.newInstance();
 dbfactory.setNamespaceAware(true);
 Document doc = null;
 try {
  DocumentBuilder dbuilder = dbfactory.newDocumentBuilder();
  InputStream =
 context.getResourceAsStream(/WEB-INF/mydoc.xml);
  doc = dbuilder.parse(is);
 }
 catch (ParserConfigurationException pce) {}
 catch (SAXException se) {}
 catch (IOException ioe) {}
 
 
 You can then grab a NodeList of some part of the document and
 iterate
 through that or you can then use Jaxen to get to specific data with
 XPath queries
 
 
 try {
  XPath xpath = new
 DOMXPath(//MyElement[@myAttribute='someSpecificValue']/

RE: Changed file name now webapp not working right

Denise,

Within your JSP page, you can put % application.log(...); % anywhere you
want to put out a message to the log.

% application.log(entering CCProcess); %

html
headtitleCCProcess/title/head
body
% if (condition) { application.log(forwarding to verify); %

jsp:forward page=/Verify.jsp /

% } else { application.log(forwarding to retry); %

jsp:forward page=/Retry.jsp /

% } %
/body
/html

I did that from the hip, and might have some typos.  Just trying to
illustrate logging within a context similar to what you are likely doing.

Noel,

I even tried changing everything back to FormValidate.jsp and it still
doesn't work...

Yes, your scenario is correct, form action was FormValidate.jsp - and is
now CCProcess.jsp, and depending on outcome of form validation,
CCPRocess.jsp will forward to Verify.jsp or Retry.jsp.  But now after the
rename I never get to Verify.jsp.  The action of Retry.jsp is
CCProcess.jsp.  What is completely boggling my mind is that it was working
perfectly before I changed the file name :( Well I guess its true what they
say, if its not broke...

And I feel pretty dumb saying this, but I do not know how to trace using log
code. I am assuming you mean add some code in the jsp file (and/or
FormBean.java?) that will write to a log file to see what is happening.
Would you be able to recommend the code and the placement of that code so I
can trace this? Or maybe point me in the right direction to some
documentation?

Thanks :)

Denise,

The front end is/was FormValidate.jsp/CCProcess.jsp, which forwards to
Verify.jsp or Retry.jsp?

You renamed it, and now when you submit the form you never get to
Verify.jsp?  You are saying that when Retry.jsp submits the form, the
form
action is CCProcess.jsp?  Have you put any log code into CCProcess.jsp
to
trace what is happening?

There was nothing meaningful in the logs no. Just the stack trace leading up
to that exception. I have not tried 4.1.18 yet. I may have to give that a

RE: Changed file name now webapp not working right

Noel,

I did as you suggested, and the strangest things are happening!!  This is my
CCProcess.jsp:

%@ page import=java.util.* %
%@ page import=com.complusdata.beans.FormBean %

% log(Entering CCProcess); %

jsp:useBean id=formBean class=com.complusdata.beans.FormBean
scope=request
  jsp:setProperty name=formBean property=*/ /jsp:useBean

%
   if (formBean.validate())
   {
 log(Form Has Been Validated - forwarding to Verify.jsp); 
%
 jsp:forward page=/CCPayments/28/Verify.jsp/
%
   }
   else
   {
 log(Error on form - forwarding to Retry.jsp);
%
 jsp:forward page=/CCPayments/28/Retry.jsp/
%
   }
%

I also added code to Verify.jsp to log when Entering Verify.jsp, and code
to Retry.jsp to log when Entering Retry.jsp - error on form.

Here is the output of my log: 

2003-01-05 22:41:49 jsp: Entering CCProcess 
2003-01-05 22:41:49 jsp: Form Has Been Validated - forwarding to Verify.jsp 
2003-01-05 22:41:50 jsp: Entering Retry.jsp - error on form 
2003-01-05 22:41:57 jsp: Entering CCProcess 
2003-01-05 22:41:57 jsp: Form Has Been Validated - forwarding to Verify.jsp 
2003-01-05 22:41:57 jsp: Entering Retry.jsp - error on form 


Now this is what I did to test.  I called my form, left two fields blank,
then submitted (form action=CCProcess.jsp).  As it should, Retry.jsp was
displayed with the appropriate error messages.  If you notice in the log, on
the call to CCProcess.jsp, entering CCProcess is logged.  BUT - even
though there were errors on the page, it was still written to the log that
control is being forwarded to Verify.jsp (even though it technically wasn't)
AND it does not log that control is being forwarded to Retry.jsp AND
Entering Retry.jsp - error on form is logged.  Then after correcting the
errors, I hit submit, and Retry.jsp is loaded again (no error messages
displayed because all data is correct).  Now this is where control should
have been forwarded to Verify.jsp.  The log shows that it is getting
forwarded, but it never enters.


Now here is the STRANGEST thing.  In CCProcess.jsp I commented everything
below the /jsp:useBean and left ONLY the jsp:forward
page=/CCPayments/28/Verify.jsp/ - this way not matter what Verify.jsp
should have been loaded.  Check out what is says in the log:

2003-01-05 23:21:05 jsp: Entering CCProcess
2003-01-05 23:21:05 jsp: Entered Verify.jsp
2003-01-05 23:21:05 jsp: Entering Retry.jsp - error on form
2003-01-05 23:21:08 jsp: Entering CCProcess
2003-01-05 23:21:08 jsp: Entered Verify.jsp
2003-01-05 23:21:08 jsp: Entering Retry.jsp - error on form

According to the log - both jsp pages are being loaded...?? I even tried
deleting everything in my work directory to make sure the new files were
being compiled.  This is all very strange and I am at a total loss :(  

Thanks so much for taking the time to look at all this.

RE: Changed file name now webapp not working right

Correction - I just tried it again with the original CCProcess.jsp, and
intentionally left errors on the form, and the log DOES indicate that
control is being forwarded to Retry.jsp (as it should).  However, the  case
still holds that when the data is correct, upon hitting the submit button,
it is logged that the form has been validated, and control is being
forwarded to Verify.jsp, and then again, according to the log both jsp's are
being loaded, yet Retry.jsp is displayed in the browser.

Log file:
2003-01-05 23:45:15 jsp: Entering CCProcess
2003-01-05 23:45:15 jsp: Error on form - forwarding to Retry.jsp

Denise,

Within your JSP page, you can put % application.log(...); % anywhere you
want to put out a message to the log.

% application.log(entering CCProcess); %

html
headtitleCCProcess/title/head
body
% if (condition) { application.log(forwarding to verify); %

jsp:forward page=/Verify.jsp /

% } else { application.log(forwarding to retry); %

jsp:forward page=/Retry.jsp /

% } %
/body
/html

I did that from the hip, and might have some typos.  Just trying to
illustrate logging within a context similar to what you are likely doing.

Noel,

RE: Changed file name now webapp not working right

Denise,

That almost looks like either Verify is forwarding to Retry or both forward
actions are being invoked.  Neither should be the case.

For kicks, I tried my own version (didn't write a fake bean or form):

CCProcess.jsp:

%@ page import=java.util.* %

% log(Entering CCProcess); %

%
   if (request.getParameter(validate) != null)
   {
 log(Form Has Been Validated - forwarding to Verify.jsp);
%
 jsp:forward page=Verify.jsp/
%
   }
   else
   {
 log(Error on form - forwarding to Retry.jsp);
%
 jsp:forward page=Retry.jsp/
%
   }
%

Retry.jsp:

%@ page import=java.util.* %

% log(Entering Retry); %

html
headtitleRetry/title/head
bodyNot verified/body
/html

Verify.jsp:

%@ page import=java.util.* %

% log(Entering Verify); %

html
headtitleVerify/title/head
bodyVerified/body
/html

Entering //localhost:8080/test/CCProcess.jsp resulted in the Retry page
being invoked, as verified by browser content and log:

2003-01-06 00:19:24 jsp: Entering CCProcess
2003-01-06 00:19:24 jsp: Error on form - forwarding to Retry.jsp
2003-01-06 00:19:27 jsp: Entering Retry

Entering //localhost:8080/test/CCProcess.jsp?validate=1 resulted in the
Verify page being invoked, again verified by browser content and log:

2003-01-06 00:22:37 jsp: Entering CCProcess
2003-01-06 00:22:37 jsp: Form Has Been Validated - forwarding to Verify.jsp
2003-01-06 00:22:40 jsp: Entering Verify

Obviously something is not right on your end.  If you want, send me the
files and I'll play.  I will be in transit all day tomorrow, but if I get
them before I leave, I can run on my laptop.

Correction - I just tried it again with the original CCProcess.jsp, and
intentionally left errors on the form, and the log DOES indicate that
control is being forwarded to Retry.jsp (as it should).  However, the  case
still holds that when the data is correct, upon hitting the submit button,
it is logged that the form has been validated, and control is being
forwarded to Verify.jsp, and then again, according to the log both jsp's are
being loaded, yet Retry.jsp is displayed in the browser.

Log file:
2003-01-05 23:45:15 jsp: Entering CCProcess
2003-01-05 23:45:15 jsp: Error on form - forwarding to Retry.jsp

2003-01-05 23:45:20 jsp: Form Has Been Validated - forwarding to Verify.jsp
2003-01-05 23:45:20 jsp: Entered Verify.jsp

Noel,

I did as you suggested, and the strangest things are happening!!  This is my
CCProcess.jsp:

%@ page import=java.util.* %
%@ page import=com.complusdata.beans.FormBean %

% log(Entering CCProcess); %

jsp:useBean id=formBean class=com.complusdata.beans.FormBean
scope=request
  jsp:setProperty name=formBean property=*/ /jsp:useBean

%
   if (formBean.validate())
   {
 log(Form Has Been Validated - forwarding to Verify.jsp);
%
 jsp:forward page=/CCPayments/28/Verify.jsp/
%
   }
   else
   {
 log(Error on form - forwarding to Retry.jsp);
%
 jsp:forward page=/CCPayments/28/Retry.jsp/
%
   }
%

I also added code to Verify.jsp to log when Entering Verify.jsp, and code
to Retry.jsp to log when Entering Retry.jsp - error on form.

Here is the output of my log:

2003-01-05 22:41:49 jsp: Entering CCProcess
2003-01-05 22:41:49 jsp: Form Has Been Validated - forwarding to Verify.jsp
2003-01-05 22:41:50 jsp: Entering Retry.jsp - error on form
2003-01-05 22:41:57 jsp: Entering CCProcess
2003-01-05 22:41:57 jsp: Form Has Been Validated - forwarding to Verify.jsp
2003-01-05 22:41:57 jsp: Entering Retry.jsp - error on form


Now this is what I did to test.  I called my form, left two fields blank,
then submitted (form action=CCProcess.jsp).  As it should, Retry.jsp was
displayed with the appropriate error messages.  If you notice in the log, on
the call to CCProcess.jsp, entering CCProcess is logged.  BUT - even
though there were errors on the page, it was still written to the log that
control is being forwarded to Verify.jsp (even though it technically wasn't)
AND it does not log that control is being forwarded to Retry.jsp AND
Entering Retry.jsp - error on form is logged.  Then after correcting the
errors, I hit submit, and Retry.jsp is loaded again (no error messages
displayed because all data is correct).  Now this is where control should
have been forwarded to Verify.jsp.  The log shows that it is getting
forwarded, but it never enters.


Now here is the STRANGEST thing.  In CCProcess.jsp I commented everything
below the /jsp:useBean

RE: need help w. viewing servlet

Tomcat does its own loading, and you don't put web-inf/ anything in your
classpath.  Just put the files in the right places, and let Tomcat do its
job.

Or do you simply mean that you don't have a package?  If you don't have a
package, just put the class in WEB-INF/classes/GreetingServlet.class.  And
the directory name *MUST* be WEB-INF.  ALL UPPER CASE, even on Windows.

RE: Memory Usage and Garbage Collection

2003-01-05 Thread Saurabh Arora

Thanks for that explanation,
 But i was just curious to know if weakmaps or similar gc interacting
cache be used to keep the mem size in control.
 Servers with high mem size would continue to keep the cache of jsp's
for performance whereas the ones with lesser mem size would still not
give the outofmemory error.

 Subject: RE: Memory Usage and Garbage Collection

 Just wanted to know, does the current implementation of tomcat
4.1.18
 also has the same problem of keeping the jsp's
  in memory. or it was only present in 4.0.4


It's not a *problem* -- it's a *feature* :-).  This is one of the keys
to
maintaining good performance on repeatedly requested pages.

Yes, Tomcat 4.1.x maintains a reference to every JSP page that has
ever
been requested (same as every servlet that has ever been requested)
until
that webapp is reloaded or removed, or you shut down Tomcat.

Given this, designing webapps where you auto-generate hundreds of
different JSP pages (which was the choice of the originator of this
message thread) is not what you really want to do.  Instead, you'd want
to
use a single JSP page for each basic *style* of output (essentially
the
JSP page would be a formatting template) that pulls in the unique
information for a particular report (from the database, from XML, or
whatever) dynamically.  Then, a given webpp would likely have 5-10 JSP
pages, instead of hundreds.

Just as an example, assume that your application back-end gave you the
data you need in some XML format, and you want to offer your user the
chance to format this data in ten different ways.  If you create an
XSLT
stylesheet to transform the data for each of the ten formats, you can
do
this all with a *single* JSP page that takes an XML data source and an
XSLT stylesheet, applies the transformation, and renders the result.
(JSTL has a tag that will do all the grunt work for you.)

If you really really want to auto-generate all the reports ahead of
time,
go ahead and generate static HTML pages -- don't waste your time
generating JSP that then has to get compiled, loaded, and executed.  As
a
side benefit, the output will get served a little faster because there
is
less overhead in serving static files.

If you really really really want to generate hundreds of JSP pages,
then
plan on buying enough memory to hold them all and be done with it.
Fortunately, this is not usually a break the bank decision (I just
upgraded my development PC to a gigabyte of memory for less than $100
:-).

If you really really really really want to generate hundreds of JSP
pages,
and don't (or can't) afford the memory to hold them all, you only have
yourself to blame for the results.

Thanks for the response.

Two questions about it:  1) why did it work with the
invoker servlet?  2) do I also change the form
'actions' to be '/MyServlet/NextJsp' from
'/myapp/servlet/MyServlet/NextJsp'?

Thanks.

  Subject: Works with invoker servlet but not
 without
 
  I'm using Tomcat 4.1.18 on Linux.  When I deploy
 my
  app (war file in the 'webapps' directory) and the
  invoker servlet is uncommented from web.xml, my
  application works fine.
 
  I then comment out the invoker servlet, and remove
 all
  references in my JSPs to 'servlet' as part of form
  'action' values, and the application stops working
  (resource ... is not available).
 
  As an example, if a form in a JSP has
  action=/myapp/servlet/MyServlet/NextJsp, I
 removed
  '/servlet'.  I have one servlet, MyServlet, that
  handles all of the control logic, so all 'actions'
  refer to this servlet.
 
  The servlet class is obviously defined, and the
  servlet mapping is as follows:
 
  servlet-mapping
servlet-nameMyServlet/servlet-name
url-pattern/myapp/url-pattern
  /servlet-mapping
 
 
 The url-pattern value should be *context*
 relative, not *server*
 relative.  In other words, it should not include the
 context path in it.
 This makes sense when you understand that a webapp
 should work correctly
 no matter what context path you deploy it on.
 
 Try this instead:
 
   servlet-mapping
 servlet-nameMyServlet/servlet-name
 url-pattern/MyServlet/*/url-pattern
   /servlet-mapping
 
 instead.
 
  This mapping is the same one that works when the
  invoker servlet is uncommented.
 
  Can someone please explain to me what is
 happening?
 
  Thank you.

Re: Memory Usage and Garbage Collection

2003-01-05 Thread Nikola Milutinovic

So the instance, and it's string, can still be GC'd, right?

Nope.

There is still a live reference to each OtherObject instance sitting in
the static HashMap cache.  Therefore, this instance cannot be GC'd, even
though *you* have released your own reference to it.  And, if the
OtherObject class is loaded from Tomcat's common/lib directory (for
example), there is no way to ***ever*** GC this instance, because the
public API of the OtherObject class doesn't offer any way to clear the
cache.


Wouldn't it be the responsibility of the Factory to worry about releasing 
objects to the GC?

I mean, if it implements caching, it should have some sort of policy when an 
instantiated (and, thus, cached) object is a candidate for GC. Obvious 
guidelines are:

- if it is not used
- if it has last been used less recently than some limit

One can also think of a non-linear function, which checks the available memory 
or has it's internal memory limit.

Nix.

RE: Changed file name now webapp not working right

Wow I think I deseerve the tomcat list schmuck of the year award... (thank
got the year just started ;) )

The way you worded that ... once I read Verify is forwarding to Retry a
light bulb went off...

As you know (and helped greatly with) I was working out previous problems I
was having with form validation.  While I was waiting for a response to a
post,  I was playing with Verify.jsp to add a button to give the user the
option to go back and make changes.  I left it non-fucntional.  So, when my
form validation problems got worked out everything was running smoothly.  I
had the urge to program that button, I was editing the file but then seconds
later decided to wait on that until I knew for sure how to do it and I could
swear that I quit without saving.  Ummm...after checking the file again it
appears that I actually did save that change... :(

The way I was trying to program the button (which I am certain is incorrect)
is onClick=jsp:forward page=Retry.jsp.  Looking at it again, I can see
that this jsp tag would be executed regardless of whether or not the button
was clicked to invoke it.  I have removed this code, but my servers are down
for routine maintenance so I will not be able to test until the morning to
see if whether or not this solves the problem.

I truly feel like a dope, and I hope you'll accept my deepest apologies for
wasting your time with this :(

Obviously something is not right on your end.  If you want, send me the
files and I'll play.  I will be in transit all day tomorrow, but if I
get
them before I leave, I can run on my laptop.

Correction - I just tried it again with the original CCProcess.jsp, and
intentionally left errors on the form, and the log DOES indicate that
control is being forwarded to Retry.jsp (as it should).  However, the
case
still holds that when the data is correct, upon hitting the submit
button,
it is logged that the form has been validated, and control is being
forwarded to Verify.jsp, and then again, according to the log both jsp's
are
being loaded, yet Retry.jsp is displayed in the browser.

Log file:

2003-01-05 23:45:15 jsp: Error on form - forwarding to Retry.jsp

2003-01-05 23:45:20 jsp: Entering CCProcess

2003-01-05 23:45:20 jsp: Entered Verify.jsp

Thanks.

Noel,

I did as you suggested, and the strangest things are happening!!  This
is my
CCProcess.jsp:

%@ page import=java.util.* %
%@ page import=com.complusdata.beans.FormBean %

% log(Entering CCProcess); %

jsp:useBean id=formBean class=com.complusdata.beans.FormBean
scope=request
  jsp:setProperty name=formBean property=*/ /jsp:useBean

%
   if (formBean.validate())
   {
 log(Form Has Been Validated - forwarding to Verify.jsp);
%
 jsp:forward page=/CCPayments/28/Verify.jsp/
%
   }
   else
   {
 log(Error on
