RE: Strange error

[Fredrik Liden]

Thanks for responding Mark,

It's so weird, I'm starting to think it's a bug in Intellij. 
When I delete the output directory and regenerate everything again I
don't get the error but then when I run it again I get this error.
It's soo annoying!

You need to look at line 125 of WebApplicationListener in the 
org.objectstyle.cayenne.conf package and see which object might be null 
that you have assumed isn't.

Well, this should be obvious by now.  JDK1.4+ ships with Xalan.  As such, it is
an "endorsed" library.  You shouldn't be putting endorsed libraries in
WEB-INF/lib.  Since Tomcat adds Xerces and xml-apis to common/endorsed, they
become "endorsed" libraries as well.  Tomcat classloaders will actively ignore
endorsed libraries sitting in WEB-INF/lib.  As such, your own versions of the
libraries are doing nothing whatsoever being there.  If you want to update
Tomcat with the latest Xerces and xml-apis, delete the existing ones from
common/endorsed and add yours there.  You can also add Xalan there, but probably
should add it to JAVA_HOME/jre/lib/endorsed (create the directory if it doesn't
already exist).  I suggest you use the "2jars" release to avoid making BCel
(which Xalan ships with... and old version at that) an endorsed library.  If
things don't work after this, then I'm at a loss.

Re: strange error when processing stylesheets: tomcat, jdk1.4, windows, xalan

[Dan Barron]

Have you tried just testing (title) instead of (./title)?  The added "./" 
seems unneceassry.

At 02:25 AM 7/1/2004, you wrote:
Hi *,
I get the following error when trying to transform a xml document with

In the stylesheet, I test for an empty string:

The error occurs:
- with ANY test condition that tests for an empty string
  (e.g. with "string-length(./entry) = 0"
- with having xalan.jar, xml-apis.jar and xercesImpl.jar in my

- NOT with JDK 1.3

It's these kind of errors that makes being a programmer a real fun!
Does anyone have a tip on what to do?

Ah, yes, and it does NOT occur when running the transforming by
directly calling xalan from the command line and not via TomCat!

What event listeners?

The object is a custom object.  The only difference I can find is that  
this object has some event listeners attached to it.  It is an  
implementation of a Tree object.  The only java objects that it uses  
are Map, TreeMap and few other util classes.

RE: strange error messages in tomcat log and mod_jk2 log

[Altankov Peter]

My production server setup is Apache/1.3.19 (built on HP-UX)mod_ssl/mod_jk/tomcat 
4.1.29 on a separate machine
I have a moderate loads of 5-10 hits per second and no really big responses (no more 
than 300k)
What I know so far is that this is caused by an attempt by the coyote connector to 
write in a already closed by the mod_jk socked.
The hints I have so far:
1. some proxy servers in the middle might explicitly close lenghty collections
2. lotso ppl blame users pressing "stop" button in browser!?
3. I follwed some forum thread somewhere (cant remember now) where the guys had 
observed as a weird bahaviour of Windows IE. They had narrowed the log entry 
appearances to a hit to a page where the request was submited like this:

They were saying that the IE evaluates the onclick and submits the form, at the same 
time requests the blah/blah.html document, and THEN decides that the blah/blah.html 
document is not needed and just closes the socket. The guys also were saying that such 
a behaviour was not observed while tested with Mozzila and Opera browsers. They have 
been able to avoid it just by making the onclick event handler return false:

Though, I have not tested it myself.

Hi!

thanx for your reply. hm. it's a very strange thing.

some questions:

are you running your application under heavy load?
are the responses very big in size?
do you use the apache2/mod_jk2/tomcat4 config on a windows nt4 box? does a dialogbox 
appear on the server with an error message stateing that the apache.exe caused an 
internal error, and after pressing Ok the apache2 server continues to run?

maybe we can find some similarities.

we have no idea what direction to look for, and the problem is very critical because a 
very big application is crashing every few minutes, so a production environment 
couldn't be setup... :-((

Ein Physiker, ein Mathematiker und ein Windows-Programmierer fahren in
einem Auto, als dieses plötzlich der Geist aufgibt. Der Physiker
schlägt vor, mal das Benzin zu kontrollieren.  Der Mathematiker sagt,
er verstehe nicht viel von Autos, aber man solle mal das Kühlwasser
überprüfen. Der Windows-Programmierer meint, er würde zuerst alle
Fenster schließen, aussteigen, erneut einsteigen und dann alle

Yeah we eventually figured out it was a noclassdeffound error, of course 
if tomcat had actually told me it could have saved me half a day of 
tracking down queer errors (well there's one i tracked down, the other 
is too strange and I'm working around it).

It's somehow getting out of a block of code encased in a try-catch of

it's an interface.

Anyway, I've got no idea what's going on, and in a fair hurry to get it

Howdy,
Is there a full stack trace or other messages in the log?  Could it
simply be a class not found exception for that interface, which is being
used by a 3rd party library your webapp relies upon?

Looks to me like you've misspelled 'Parameters'.  Assuming there _is_ a
getParameters method... I've only ever used getParameter.

RE: Strange error

[Andy Eastham]

Felipe,

Just one additional idea:

Are you executing another command on the same connection?  This destroys the
result set.

Eg, if you are trying to loop over the result set, and are using the same
connection to do an update or delete on this or another table, you will get
this sort of error.

Howdy,
Make sure not to release a connection before you're done processing result sets ;)  
Same thing for closing statements, etc.

Either your database connection is timing out or else you are trying to use
a ResultSet obtained from a Statement which, in turn, was obtained from a
Connection which you have closed yourself.

If you're running JDK 1.4.1 or later, it's not Tomcat -- it's the JDK that
doesn't like this.

JDK 1.4.1 tightened up rules that have always been in the Java Language
Specification (but never enforced by javac) that you can't import an
unpackaged class.  That's exactly what you are trying to do here.

Place your classes in packages and they'll work fine.

RE: Strange Error

[Rob Grundel]

I'm not sure if this sheds any light on the situation...BUT...
I am running this servlet on another server and I just installed all the
components onto the new server and now it will only work if I type in the
path into the browser but not if a form action OR a redirect.

We are testing on multiple browsers. But thank you. :)

Re: Strange Error

[Randall R Schulz]

Rob,

If you don't want to use a better browser, you should at least reconfigure 
your IE to give you more complete and accurate error mesages. I'm sure the 
method varies from version to version of Windows and IE, but I'll tell you 
how it's done on Win2K Pro with IE 6:

Open your "Internet Properties" control panel. This can be done in the 
"Control Panel" folder in a Windows Explorer windo or via the "Control 
Panel" sub-menu in your system's "Start" menu.

Once you have the "Internet Properties" control panel open, switch to the 
"Advanced" tab (the right-most one). Look for the option "Show friendly 
HTTP error messages" and disable it. What's friendly to a real person is 
not necessarily friendly to a S/W developer...

If that doesn't disclose enough information to solve the problem, report 
back with more detailed error messages.

By the way, if you're developing software for general public release or for 
release to a user community not under some sort of single-browser dictate, 
you should test your software with a variety of browsers. I use Netscape 
4.7x, Mozilla and Opera and IE. That's a rather minimal set, actually. For 
Mac users, there's iCab, too and in general there's a larger set of 
browsers than many people realize. At least test on a few unless you know 
your user community is using a restricted set of browsers.

Good luck.

Randall Schulz

this is not very helpful.  i would suggest you use a browser that
doesn't hide errors.  also, what do the logs say?

stab in the dark:  you defined doget() in your servlet but not
dopost() and your form does a post.  stab #1: if you have defined
dopost() perhaps there is an error in it.  we would have to see your
logs to tell you anything more.

and after reading that, i don't know if i really want to help you any

RE: strange error..

[Randy Layman]

Am I correct that your "servlet" doesn't extend
javax.servlet.Servlet or javax.servlet.http.HttpServlet?  If so, that is
your problem - servlets must extend Servlet or one of its subclasses.

Toncat runs, but does not work, can someone please help me with this?

RE: Strange Error at JspParseEventListener.java:1146

[Larry Isaacs]

This error doesn't show where the real error is.  The
JspParseEventListener.processTaglibDirective() suggests there
is a problem related to a tag library your web application is
using.  My guess is that "java.lang.AbstractMethodError"
means the problem probably isn't in the JSP page being
invoked.  Perhaps you could start with a blank JSP page
and start adding stuff from the one that doesn't work and
see at what point it stops working.  Hopefully that will
give you a clue about where the problem is.

Shailendra,
Have you checked the file permissions on the .class file?
Could be that you have permission to write to this file when you do it
manually ,
but the user associated with the JWS does not have write permission.

I would remove the original WebAppA's work
(%TOMCAT_HOME%\work\yourWebAppA)directory to be sure you are not
picking-up anything from there. Do this before you restart Tomcat after
you have done your directory renames.

RE: strange Error 404

[Wolfgang Egger]

Servus Wyn,

first thanx for your answer.

I don't think so, because of the following behaviour:

Our WebServerDirStructure looks like this

/websites/WebAppA
/websites/WebAppA/WEB-INF
/websites/WebAppA/WEB-INF/classes
...
/websites/WebAppB
/websites/WebAppB/WEB-INF
/websites/WebAppB/WEB-INF/classes
...

as written in my first mail the whole site WebAppA is working as expected,
the WebAppB only shows Error 404
If I remove /websites/WebAppA

and rename /websites/WebAppB with /websites/WebAppA,
the whole WebAppB is working (with the URR bla/WebAppA/fasel)

Because of this I assume, that something in the configuration of tomcat
doesn't like WebAppB.
I have done a grep "WebAppA tomcat/conf/*" and a "grep WebAppB
tomcat/conf/*".
The result is, that all entries for WebAppA are the same as the entries for
WebAppB. Near the same, because the string WebAppA is replaced by WebAppB in
each entry.

Are there any other locations apart from tomcat/conf, where I have to do
some configuration respectively WebAppB.

Greetings from Berlin

  Wolfgang

Re: strange Error 404

I'm sure the problem is with the URL used to access the servlet of
WebAppB.
Look at the Tomcat output after you get the first 404 error.
That should show you how Tomcat is trying to find the servlet.
The Tomcat output will show the "context" + "pasted in URL".
If your servlet is not at the combination of those two items,
it will not be found.
You could map your servlets if you want share them from one web app.
to another.
