RE: Tomcat dies... help!

[Martin van den Bemt]

There are some bugs in ajp12 which can cause this. Since ajp12 is frozen and
not as fast as ajp13 it is best to use ajp13 or the old mod_jserv.

For one year we are using it on our server. And this package is faster than
the sun's package.

Has anyone tried IBM jdk/runtime environment on Linux with Tomcat 3.2.3?

I'v got sun jdk 1.3, running on Red Hat 7.1, with apache 1.3.20, and 
tomcat 3.2.3.
I was wondering how or if IBM's jdk/runtime works.

Elementary question about Tomcat

[Bhamidi Krishna]

Hi,

I am posting a very elementary question about Tomcat.

I have written a JSP application that I want to use undes tomcat. Do I need 
to place it under examples/jsp? I placed the application in the jsp 
directory level, Tomcat looks for class files under examples/web-inf whereas 
the class files are under (my directory)/web-inf.

Can I configure Tomcat to read jsp files and class files in my own directory 
other than under examples/jsp and examples/web-inf? I searched around but 
could not find documentation anywhere.

Thankyou,
Krishna.

Rejected Message

[Administrator]

The attached mail message has been rejected for the following reason:

Could not extract file 'MANIFEST.MF' from archive '[5]Calendar.jar'.

Additional Information:

It could be that either the file is password protected or else corrupted.  Make sure 
that you check the attachment manually and virus check it before you approve it. 

WARNING: The archive file could contain VIRUS infected files!!!





Amos,

I fixed a few things for you. Try my version.

#1: There was no need to keep allocating StringBuffers, I just passed the output
PrintWriter.
#2: I fixed your form action to use the request context path for the action
instead of hard-coding it.
#3. I added a call to out.flush () before your out.close () as I suggested
before to force the output stream to flush.

Let me know if it runs fast now...

"Keystore tampered ..." usually indictates that the keystore did not like the 
password it was given. You should have gotten a "no suitable provider" 
exception if you didn't have your java.security file set up right, so I'll 
assume you do. The exaxt steps to get SSL working are listed a little further 
down.

I'm currently working on exactly such a document. :)

There are no changes whatsoever necessary to run SSL aside from what is 
documented in server.xml. Here are the exact steps:

1. Download JSSE and put the three jar files in {JAVA_HOME}\jre\lib\ext (it's 
not necessary to put them in the CLASSPATH unless your own classes rely on them)

2. DO NOT put the three files anywhere in the internal Tomcat tree (lib, 
server/lib, or common/lib). This will hose you.

3. Add the following line to your {JAVA_HOME}\jre\lib\security\java.security 
file (in the first section of settings, you'll see it):

   security.provider.9=com.sun.net.ssl.internal.ssl.Provider

The number is simply the order in which the JVM attempts to find suitable 
security providers. Just pick one that is not already in use by any 
existing "security.provider..." lines.

4. Execute the following in a terminal command-line:

   keytool -genkey -alias tomcat -keyalg RSA

It will start asking you questions about your cert. The only really crucial 
ones are when it asks you for a password (at two different times). You must use 
the same password in both places. You can type in the Tomcat default, which 
is "changeit" (all lowercase), or you can make up your own.

5. Uncomment the secure connector in {TC_HOME}\conf\server.xml

6. If you specified a password other than "changeit" when generating the 
keystore, edit the  tag nested within the relevant  tag. 
Add an attribute called "KeystorePass" with the value of your password. Your 
 tag should now look something like this:



If you just used "changeit", you can skip this step.

That's it. When you start Catalina up, it should now be running a secure socket 
on the specified port (8443 by default). No modifications to catalina.bat or 
any additional JVM parameters are necessary.

Note: Since I am addressing your specific problem, I left out the whole issue 
of where Tomcat looks for the keystore file in the above step-by-step. Tomcat 
obviously found the keystore file where it expected it in your case, but other 
users referencing this thread should be aware that I glossed over the whole 
keystore location issue. You can read all about it in my upcoming SSL guide =)

> > Do I have to make include a specific keystore in the catalina.policy

Nope, that shouldn't be necessary.

KeystoreFile and KeystorePass attributes on the  tag are where you put 
custom values, if either the location or password are anything other than the 
defaults.

You are quite welcome :)

> > France, Bordeaux, xml and gay pride.

That sounds like the possible anwers to a multiple choice question ;-)

Let me know if you have any other problems. I would recommend undoing whatever 
changes you made to Catalina.bat, including any JVM parameters you may have 
added, and following the above steps from scratch.

Good luck!

RE: Newbie help needed: installing TOMCAT on linux

[Bob Wilson]

Did you have a look at the documentation on the Apache site?  That's a 
pretty good starting place.  This is where I got started and I'm running 
Apache 1.3.20, Tomcat 3.2.3, Jetspeed 1.3a1, JDK 1.3.0_03 on SuSE Linux 7.1. 
  I suspect your setup will be very similar.

Here are a few sites to help...

www.apache.org

www.e-gineer.com/instructions/install-apache1xx-on-linux.phtml

I also found a really good article by doing a Google.com search in the user 
groups.  Search for 'apache'.  You should be able to come across an article 
by Chad ([EMAIL PROTECTED]) with the subject Apache Tomcat using mod_jk on 
Linux.

Newsgroup is comp.os.linux.networking

Hope this helps!

RE: Servlet Runs SLow

[Alberto Gobbi]

Hi,
I am having the same problem, and for me the reason is that when I am
running tomcat and netscape on the same mashine, netscape will use all the
cputime while waiting for the answer from tomcat. This is stupid since
netscape could just stay idle, but that is how it is. so as long as netscape
is in the foreground (active window) tomcat will get only very litle of the
cpu. To see this just keep taskmanager running sorted on %cpu usage, yuo
will see netscape using 99% of the cpu while doing nothing.
To solve this problem you can do the following:
- run tomcat on different server.
- increase the priority of tomcat.
- decrease the priority of netscape.

Sorry, I'm out of ideas.  The servlets I'm working on work fine in both
Netscape and IE.  You may want to try to collect some more information
(log begin/end times in the servlet, use a network monitor to see what
is happening, try different Netscape settings) and see if anything
unusual is happening.

That's one I've never seen before.

Have you followed the instructions (inside server.xml) exactly?

Is there really supposed to be a backslash (\) before "com.sun" ?

You can avoid the need to modify catalina.bat by setting an appropriate
value for the CATALINA_OPTS environment variable to the set of properties
you want to pass.  But I've not had to do this.

Tomcat 4 doesn't yet have a web connector for IIS.  That's in the future
plans.  You're probably just seeing IIS serve the file as static content.

I can't get TOMCAT 4b6 and IIS5 to work over SSL

[Curtis Dougherty]

I have Tomcat 4b6
IIS 5
Win2K

I have the redirect working...I think
I have an SSL Certificate installed and working on my Win2K box


When I request the INDEX.JSP page from my site
https://mysite.someplace.com/fooey
I GET the file AND I see the SSL icon on the browser but the ONLY thing my

Why is that?

When I point my browser to http://mysite.someplace.com:8080/fooey I GET
COMPILED JSP code that RUNS.
What am I doing wrong - Besides running IIS5 (the suits made me do it).

Include issues?

[Dan Garcia]

I have a site where jsp pages do a lot of includes...  I'm using a 
cron job script calling a wget to check that the site is still up, and
i have something that'll page/email me if anything's wrong with the page.

What i'm seeing occur often is wget will only end up getting a partial
page back, and the 'boundry' of where this ends is almost always the end
of an include (e.g. it seems like a page gets included, and once it gets
included, processing stops).

I'm not seeing terribly many errors in the logs show up, at least nothing
relating to this - but I am seeing a LOT of the connection reset by peer
messages (which someone else, from the archives i searched/read, seemed
to feel was a mostly harmless error).

Any thoughts on why this would be happening?  I'm running jakarta 3.2.1, 
using ajp1.3, apache 1.3.12, a redhat 7.1 based box with IBM's 1.3 jdk, sr6.

--Dg

jakarta-tomcat-3.2.3.zip "conf" files are blank

[Shawn]

I put in the conf files I had been using for 3.2.2 and 3.2.3 seems to be
working fine.  Could that lead to some problems I haven't discovered yet?

RE: Newbie help needed: error running JSP

Well, of course the stack will be container-specific =)  In WebLogic, the
exception will be something like com.weblogic.blah.foo with a different
message.  The exception message there seemed descriptive enough to debug.

RE: Newbie help needed: error running JSP

[Jann VanOver]

Look at the line:
 
jsp.f_00025rm._0002fjsp_0002fform_0002fForm_0002ejspForm_jsp_0._jspService(_
0002fjsp_0002fform_0002fForm_0002ejspForm_jsp_0.java:122)

THIS is where your error occurred.  Tomcat compiled your JSP page into the
named java file.  Look in your tomcat\work directory for this file.  It will
be in a folder named for your context.  Look at line 122 in that file and
see where it found a problem.  You can usually tell from that what you did
wrong.

I only worked with JRUN for a short while, but I seem to remember that it
was much nicer than Tomcat in this one respect, giving you the line number
back into your .jsp file instead of making you dig through the java file.

Hiya Ken,

Not to be a jerk or anything, your "newbie help" questions are fine and all,
but the problem is that the only connection they have to Tomcat is that
you're using the container.

jakarta-tomcat-3.2.3.zip "conf" files are blank

[Jesse_Perez]

I've been using Tomcat 3.2.1 for last 8 months and decided to upgrade to 3.2.3.
I downloaded "jakarta-tomcat-3.2.3.zip" but all the files in the "conf"
directory are blank.
I downloaded a second time but still bad files.

This is supposed to be a Release build.

Has anyone else experienced this?

I can't get TOMCAT 4b6 and IIS5 to work over SSL

[Curtis Dougherty]

I have Tomcat 4b6
IIS 5
Win2K

I have the redirect working...I think
I have an SSL Certificate installed and working on my Win2K box


When I request the INDEX.JSP page from my site
https://mysite.someplace.com/fooey
I GET the file AND I see the SSL icon on the browser but the ONLY thing my
stupid browser shows is the UNCOMPILED JSP CODE
Why is that?

When I point my browser to http://mysite.someplace.com:8080/fooey I GET
COMPILED JSP code that RUNS.
What am I doing wrong - Besides running IIS5 (the suits made me do it).

Newbie help needed: error running JSP

[Kenneth Litwak]

   I just ran my first JSP that uses a form and got an
error. Unfortunately, the stack trace doesn't tell me
where in the JSP the error occured (that I can tell)
or where in my helper bean the problem ight be.  I'd
heard that JSPs are hard to debug, and now I see why. 
The JSP engine is not very helpful with what's wrong. 
Here's the stack trace, followed by the JSP code.

Just for the record, the last sentence is *not* true for Tomcat 4.  It
reloads if *any* previously loaded class is recompiled.

Yep, Martin is right. 
It takes the fun right out of reloadable=true, don't you think so?
When you put objects in your servletcontext or in a session you will also
have to restart Tomcat because of nullpointerexceptions... 
(Do you guys also have a restart-tomcat-batchfile?)

Okay, my advise would be: Do not rely on reloadable is true if your
servlets do anything more than pitting out a straitforward response.

Good luck,
Erwin

RE: auto-reload classes

[Martin van den Bemt]

It does.. Every request triggers a check if the file has been in updated and
changed, so if you have a lot of hits, it will be noticable.. Since
reloading (at least my experience) is not the most stable (it can have some
strange results..) thing that could happen to you, I would not use it in
production environments anyway. For development it is ok.. If you have 10
servlets and 600 supporting classes, reloading doesn't help very much...
(catalina should handle this properly btw..)

In tomcat 3.3 (now beta) you can select ( is default as far as I know)  to
do context reloading, which I personally prefer while developing..

No, it MUST be "127.0.0.1", what you have there is
a typo. Also, there's only one file it should be in,
"hosts". Anything else is a mistake or a Microsoft
machination (LMHOSTS is not a traditional network config
file). If that's not working for you try addressing
your server as "http://127.0.0.1/"; + your tomcat examples
dir, that will work.

the auto-reloading of TC4.0-b6/b7 works well, if you update a class, after
a while(perhaps it is before next accessing of this class), this updated class

has already been auto-reloaded, so you don't need to restart TOMCAT.

Re: Trouble running a servlet

[Kenneth Litwak]

  I'm trying to run Tomcat on W2K disconnected from
the Internet.  In asking for help, I got one reply
which said
What solved the last of my disconnected-laptop 
issues (on Win98 at least)  
was adding a LOCALHOST entry in 
"c:\windows\hosts" (create it if needed):

  127.0.0.1 localhost

Win98 looks here first before it tries accessing 
your configured DNS
servers, which is when it would try to access the 
network.

Unfortunately, my system already has hosts files and
they all include 127.0.01 localhost.  Thanks.

public key for signature on jakarta-tomcat-3.2.3-src.tar.gz not found

[Aaron Seth]

I just downloaded Tomcat 3.2.3 and before even attempting to build it
I have a problem: it appears that the signature on
jakarta-tomcat-3.2.3-src.tar.gz doesn't match any of the Apache
developer signatures in the KEYS file distributed at
http://www.apache.org/dist/

(It also appears that someone else pointed out this very same problem
awhile back, but I didn't see any replies in the mailing list
archives, so I'll inquire again).

I'm using GNUPG 1.0.6 on FreeBSD 4.3 to attempt to check the
signature.

Re: interesting mistake in the tomcat implementation jsp standart.

This is a user error.

It is not valid to reference pageContext outside the actual execution of
the tag.  Once doEndTag() is called, none of the instance variables have
any valid values.

Re: mod_jk.so + apache

[David Smith]

I place mod_jk.so in my /etc/httpd/modules directory and then used
LoadModule jk_modulemodules/mod_jk.so

in httpd.conf.  Either case, check where your mod_jk.so file is and set the 
LoadModule directive to it.  Either absolute or relative path to /etc/httpd 
should work.

I'm also on a Mandrake 8 box, so individual OS and/or Apache install mileage

Ajp12Interceptor, tomcatAuthentication="false" not functioning ?

[Joe Van Demark]

I'm running Apache/tomcat 3.3 Beta with jserv.

My server.xml contains the following RequestInterceptor tag/element

  

But it doesn't seem that tomcatAuthentication is actually disabled.

Looking at the code I see the following

The AjpInteceptor instantiates both AjpRequest and AjpResponse objects.
The instantiation of AjpRequest in turn instantiates an instance of Ajp12
which is where we read off the stream from jserv.

Both AjpInterceptor and Ajp12 default tomcatAuthentication to true.

when Ajp12 is reading the stream it will ignore the remote users if
tomcat Authentication is true.

if (isTomcatAuthentication())
dummy=readString(ajpin, null);
else

which is what is happening.

It would seem to me given the Request interceptor definition
in server.xml that Ajp12 should be reading the remote user,
i.e. tomcatAuthentication is false.

Since Ajp12Interceptor instantiates Ajp12 I would expect given
the server.xml def it would make a call to Ajp12 to set tomcat
authentication to false. This might possible occur in the
processConnection method:


if( reqA==null || resA==null ) {
reqA = new AJP12Request();
reqA.setSecret( secret );
((AJP12Request)reqA).setTomcatAuthentication(
isTomcatAuthentication());
resA=new AJP12Response();
cm.initRequest( reqA, resA );
}

But it would require that the local instance field tomcatAuthentication 
be set to false
if it were to work at all. None of this is happening as far as I can tell.

Basically I don't see a path through the code which would disable 
tomcatAuthentication
that corresponds the the server.xml Request Intercepter definition.

The only way I've been able to disable the tomcatAuthentication and read 
a remote_user
off the jserv stream was to modify Ajp12, defaulting 
tomcatAuthentication to false.

Any insight would be appreciated.

Tomcat 4.0 and IIS

[Patrick Peralta]

Hello List,

I've looked around on the website and mail list archives, but I can't seem
to find out how to set up IIS to redirect to Tomcat 4.0.  I've read this
document:

http://jakarta.apache.org/tomcat/tomcat-3.3-doc/tomcat-iis-howto.html

but it's for 3.3.  It does not appear to apply to 4.0.

Can anyone point me to documentation that gives directions on how to do
this?

Thanks!

Tomcat stops serving requests...Please help

[Venu Babu]

Hi! 
I posted this message  couple of days back. I didn't get any response. So I
am posting again.
Please help us out.
we are using Tomcat 3.2.1 with Apache http server. We are using this
setup in production. After running 3 days, Tomcat stopped serving requests
and throws null pointer exception when tried to access any JSP. See the
exception below...

Internal Servlet Error:
java.lang.NullPointerException at
org.apache.tomcat.core.ServletWrapper.doService(ServletWrapper.java:404)

Before this happened, there were some "Connection reset by peer" errors.
Can someone please help us on this.

Let's start with a simple experiment.  Start up Tomcat and request the
following URL:

  http://localhost:8080/examples/WEB-INF/web.xml

What happens?  You get a 404 error, even though the web.xml file is really
there.  This is based on a Servlet Specification restriction that
*nothing* inside the "/WEB-INF" directory may be served directly to a
client in response to a request.

However, it is legal to access these contents from within a servlet or JSP
page, or access them through a request dispatcher.  For example, I could
read the contents of web.xml myself like this:

  InputStream is =
   getServletContext().getResourceAsStream("/WEB-INF/web.xml");

or, if I have a JSP page "foo.jsp" in the /WEB-INF directory, I can do
this:

  RequestDispatcher rd =
   getServletContext().getRequestDispatcher("/WEB-INF/foo.jsp");
  rd.forward(request, response);

or (from a JSP page):

  

This works because the access is from *inside* the web app, whereas the
following request (from a client) will generate a 404:

  http://localhost:8080/examples/WEB-INF/foo.jsp

In summary, if you are using an MVC style application architecture like
that proposed in J2EE Blueprints (or in Struts), you can easily make it
impossible for your users to navigate directly to a page without going
through the controller first.

Re: Re[2]: Re[2]: Servlet Runs SLow

[A.L.]

Jonathan,
  Thank you very much.  It may take me a little while,
but I am going to make every effort to understand the
improvements you made.
   I will say, that netscape is loading the html much
quicker.  Nevertheless, once in a while it does take a
while to load the page...  Sometimes it even loads the
page, but continues to appear as if more data is
loading.  I guess that these are just netscape issues.

Re: db connection denied access

[Jeff Kilbride]

You need to read chapters 4.2 and 4.3 of the MySQL manual:

http://www.mysql.com/doc/P/r/Privilege_system.html
http://www.mysql.com/doc/U/s/User_Account_Management.html

MySQL has a somewhat strange privilege system for granting access to the
database. But it's very flexible, once you learn it.

If you're going to be using MySQL, do yourself a favor and buy this book:

http://www.amazon.com/exec/obidos/ASIN/0735709211/qid=997901246/sr=2-2/107-4
535935-5049369

It's invaluable.

catalina SSL

[cib]

Hi
I'm getting used to Tomcat but not enough to get it work.
Trying to install the SSL connector, but always getting a java IO exception,
"keystore tampered". I'm a complete newbie either in tomcat or in ssl, so I
surely didn't do things right. Is there a good tutorial for this (I mean for
catalina and ssl) , because most of litterature is relevant only for Tomcat
previous versions, and Sun's documentation deals with java classes, not with
applications that needs to be configurated through server.xml.

So, do I have to make changes to the catalina.bat, to include (in the
dostartsecure / dorunsecure) the lines:
-Djava.protocol.handler.pkgs=\com.sun.net.ssl.internal.www.protocol

Do I have to make include a specific keystore in the catalina.policy using
policytool.exe?

How to modify the tomcat server.xml 's ssl connector to show the keystore
and keypass?

Thanks for any hint on this wild matter.

Re[2]: Re[2]: Servlet Runs SLow

[Jonathan Pierce]

Amos,

I fixed a few things for you. Try my version.

#1: There was no need to keep allocating StringBuffers, I just passed the output
PrintWriter.
#2: I fixed your form action to use the request context path for the action
instead of hard-coding it.
#3. I added a call to out.flush () before your out.close () as I suggested
before to force the output stream to flush.

Let me know if it runs fast now...

Tomcat embedded in Apache

[Kemp Randy-W18971]

 I found an article at http://www.linuxdevices.com/articles/AT7102892618.
The article says this
Apache 2.0 -- This is still in alpha now, with beta and final releases due
at monthly intervals. It is faster and runs on more operating systems with
the same level of stability as on Unix, and also supports dynamically
loadable modules better. The Tomcat Java engine is built-in, enabling Apache
to natively run Java Servlets and Java Server Pages.

Does that mean that the Tomcat engine will be part of the Apache download?

can you explain in more detail on the last paragraph:
put those JSP pages inside the /WEB-INF
directory.  This works because the container will refuse to serve
anything
under /WEB-INF directly to the user, but RequestDispatcher.forward()
can
still be used to display them.

Yes, but only if your users are accessing the JSP pages directly.

If you're using the MVC architecture in the recommended fashion, all
requests should flow through the controller, *not* go directly to the
pages.  So, the question is how does the user submit requests to your
controller?

In Struts (disclaimer - I'm the primary author, so I'm more familiar with
it and undoubtedly biased :-) the usual pattern is to use extension
mapping to map requests to the controller.  A common pattern is to is to
use a "*.do" mapping (implying "go do something").  So, a typical URL
would be something like:

  http://www.mycompany.com/myapp/submitPurchaseOrder.do

Now, if I want to manage who can submit purchase orders, it is *this* URL
that I care about protecting.  If the user is allowed to submit purchase
orders, they should be allowed to view the submit confirmation screen that
follows (i.e. where your front controller forwards to after completing the
transaction), right?  Thus, it doesn't need any extra protection.

To avoid users inadvertently or maliciously trying to access JSP pages
directly, you can place them in /WEB-INF as I described earlier.

RE: Does the servlet security model work with the J2EE Blueprint MVC?

[Jerome Jacobsen]

What I meant is the declarative part of the security model.  My app has a
single Front Controller JSP.  See below.

<%@ page contentType="text/html;charset=WINDOWS-1252"%>

<% ctrl.init(config, application); %>




Can I *declaratively* control access to the other JSPs by specifying
 and  elements in the deployment
descriptor?

Thanks,

Not at all.  You've got at least a couple of approaches to consider:

* If your MVC architecture uses different URIs for different logical
  transactions (i.e. you are using either path mapping or extension
  mapping to map to the controller component) you can protect those
  URIs with appropriate security constraints.

* Your controller component can (in addition to or instead of the
  restrictions based on security constraints) apply additional role-based
  checking -- perhaps defined in the configuration settings for the
  controller -- by calling request.isUserInRole() to check whether the
  user is authorized for one or more roles.

* Roles can also be used in the view layer to change the presentation
  (for example, a manager might have more menu options to choose from
  than a regular user).

In an MVC-architected web app, your primary concern is whether the user
can perform the transaction that they requested.  If they can, you
naturally want them to see the results of performing that transaction, so
there is no need to protect the RequestDispatcher.forward() used by the
controller to forward control to the ultimate view component.

But what if you have users that try to navigate to your JSP pages directly
(and perhaps bookmark them).  You can take advantage of a related
specification requirement, and put those JSP pages inside the /WEB-INF
directory.  This works because the container will refuse to serve anything
under /WEB-INF directly to the user, but RequestDispatcher.forward() can
still be used to display them.

Re[2]: Servlet Runs SLow

[Jonathan Pierce]

The problem is probably something you are doing in your servlet. 
Try hitting the /examples/servlet/SnoopServlet in your action instead of your
/jd/Calendar call and see if it is fast.

 If you want, send me the source to your servlet and I'll take a look at what
you are doing that Netscape is sensitive to. 

Perhaps you are not flushing the output stream in your response.

Sorry, I'm out of ideas.  The servlets I'm working on work fine in both
Netscape and IE.  You may want to try to collect some more information
(log begin/end times in the servlet, use a network monitor to see what
is happening, try different Netscape settings) and see if anything
unusual is happening.

Re: Servlet Runs SLow

Sorry, I'm out of ideas.  The servlets I'm working on work fine in both
Netscape and IE.  You may want to try to collect some more information
(log begin/end times in the servlet, use a network monitor to see what
is happening, try different Netscape settings) and see if anything
unusual is happening.

RE: Servlet Runs SLow

[A.L.]

I don't see how it could be the form submission if it
runs fine in explorer.  
Plus I can see Tomcat receive the request immediately
after I submit the form. 

I will meanwhile try to register a start and end time.

RE: Servlet Runs SLow

[Cato, Christopher]

Netscrape, forms and tables together is a very tricky subject. I recommend
running your HTML output through HoTMetaL to eliminate any errors. I can see
that you are missing a space in the second form opening, between NAME and
ACTION. 

Also, Netscape is very very sensitive on where you open and close your
forms, especially inside tables. Can't seem to remember if it was that you
have to open and close outside the table or if it was inside. I just know
it's sensitive as h**l. Run into this problem quite a few times.

And, yes, Netscape and large tables do not go well together.

Re: db connection denied access

[Richard Draucker]

Thanks, I found the problem.  Probably shoulda posted this on the MySQL 
group, sorry.  Using the host ip in the connection url for the db generates 
the error.  Using 'localhost' or any host name that the database considers 
valid works just fine.

Re: Servlet Runs SLow

[A.L.]

The first time I load the page in Netscape everything
seems fine,  it loads almost instantaneously. 
However, when I submit the query to change the month
calendar, netscape takes a while to reload the page
and show the new calendar.  I can see that TOmcat
receives the request immediately, and I assume that
since Netscape appears to be loading it receives the
response immediatley.

Thanks,
  -Amos

Re: Servlet Runs SLow

[Jim Seach]

I copied the html into a static file and was able to bring it up
immediately in Netscape 4.76, so it doesn't appear to be the contents
of the form that is the problem.

Does it take a long time to display, or does it just not appear to
finish loading?  I have also noticed that sometimes even after the page
has loaded, Netscape still appears to be working.  So far, I have just
ignored it.

problems on running build.bat in sample

[Alice Li]

Hello, everyone:
 I copied sample directory to C:\tomcat\webapps from
C:\tomcat\doc\appdev. Then I run build.bat which is
 in sample directory. I always get these error messages:
 Registry key 'Software\Javasoft\Java Runtime
Environment\CurrentVersion' has value '1.2', but '1.4' is required.
 Error: could not find java.dll
 Error: could not find Java 2 Runtime Environment.
  
 I am using Tomcat 3.2.3 in Windows Me.
  
 Any advice is really appreciated.
 Thank you very much.

Nah, you have to use the headers, a legitimate

header. Unfortunately you can't count on spammers to be
so gracious as to be sure to include the bulk header
either. Only the technically incompetent ones.

Re: db connection denied access

[Rob S.]

> java.sql.SQLException: Server configuration denies access to data source

-> 

It's a SQLException, so it looks like you've established a pipe between your code and 
the server (that error message would imply its Tomcat's fault), but in a way the 
*database* server doesn't like.  I'm not sure why MySQL would deny you access...

Re: Servlet Runs SLow

[Jim Seach]

I agree - it's worth looking at the client.  Do you have any large
tables?  I have had problems in the past with Netscape taking a long
time (> 5 min) to load tables with several thousand rows.

Does the servlet security model work with the J2EE Blueprint MVC?

[Jerome Jacobsen]

Hello,

The Java Servlet Specification (Version 2.3, Draft 2) under SRV.12.2 states:

"The security model applies to the static content part of the web
application and to servlets within the application that are requested by the
client. The security model does not apply when a servlet uses the
RequestDispatcher to invoke a static resource or servlet using a forward()
or an include()."

Does this mean that using the MVC architecture with a Web controller as
described in the J2EE Blueprints precludes the use of this security model?

-Jerome

Re: Servlet Runs SLow

[Denis Haskin]

Do you know for sure the difference in 'load' time is at the server, and 
not at the client?  What's the content coming back from the server?  I 
would grab a copy of that, put it in a file, and load that in IE and 
Netscape to see if there's any difference in load times.

I suppose it's possible that IE and Netscape are sending different http 
headers that are getting handled differently at the server, but this 
seems unlikely.

Are you sending these requests straight to Tomcat, or are they going 
through a web server first?

not working with tomcat 3.2.3

[Taavi Tiirik]

I have

...


404
/error404.jsp


...

in my web.xml file and for some reason it is not enough to get
error404.jsp to show up when I hit a non existent page.

Is there some other configuring that is needed in order to
make it working?

I get following debug messages when I access non existent page.jsp
(ta is a name of my webapp):

2001-08-15 16:35:08 - Ctx( /ta ): 404 R( /ta + /page.jsp + null) null
2001-08-15 16:35:15 - Ctx( /ta ): 404 R( /ta + /page.html + null) null

Any ideas of what might be wrong? I am using tomcat 3.2.3 on Win2000
with ie5 (friendly error messages are disabled).

with best wishes,
Taavi

db connection denied access

[Richard Draucker]

This is odd and I'm stumped.  I have a simple db connection class in a jar 
under ~app/WEB-INF/lib.  I have a servlet under ~app/WEB-INF/classes that 
imports this connection class.  The mm.mysql driver jar also resides in this 
WEB-INF/lib.
The servlet accesses the connection class just fine.  But, when the 
connection class attempts a connection to the database I get the error:

java.sql.SQLException: Server configuration denies access to data source

However, if I cut 'n paste the code from the connection class into the 
servlet I have no problem with the connection or data retrieval.

FYI: 
RH7.1 new installation
jdk 1.3.1
Tomcat 3.2.1
MySQL 3.2.2

[Martin Schaefer]

hi,

i'm setting up tomcat to run with iis on winnt server 4. tomcat itself 
is running fine as a service, i can run the examples if i use the tomcat 
port.

i cannot start the isapi filter in IIS, and i get the follwing error in 
the event viewer on startup:

Source: W3SVC Type:Error
The HTTP Filter DLL c:\tomcat\bin\isapi_redirect.dll failed to load
The Data is the error.

the path is correct, i downloaded the dll twice and i have checked all 
the registry entries again and again. has anyone had this problem and 
has anyone got any ideas?

thx

Hi Christian,

Not to be skeptical, but it doesn't *sound* like a Tomcat problem.  As well,
the page isn't "freezing" per se, which would imply some sort of time-out,
it's just looking the same when you hit it again.  You'll need to provide

RE: That annoying ClassNotFoundException again

[Larry Isaacs]

I haven't yet played with JDK1.4 yet.  However, comments I have heard
suggest that it may come with an XML parser built in.  I think
Tomcat 3.1 requires xml.jar be used which may be conflicting with
the build in XML parser.  I would recommend upgrading your
Tomcat.

if the file isn't executable (chmod +x) or you don't have access to that

allow messages with 'Tomcat', 'context','mod_jk' etc.,
in the subject and then moderate only the messages
without those keywords.

Of course this guy can post to the list and I still
can't from my subscribed account(outlook's
multipart/alt 'feature'). I guess they haven't fixed
our exchange server yet :(

Pure Linux Problem: problems with Java 1.3.0_02 on Linux.

[Allan Kamau]

Hi,
This is not a tomcat question sorry of the
inconvinence.
I wonder if there is anyone here successfully running
Java 1.3.x on Red Hat 7.1.

#java somejavaprogram
/usr/java/jdk1.3.0_02/bin/java: /usr/bin/cut: No such
file or directory
/usr/java/jdk1.3.0_02/bin/i386/native_threads/java:
error while loading shared libraries: libjvm.so:
cannot load shared object file: No such file or
directory


I have followed the instructions from sun's site which
read that one should install
compat-libstdc++-6.21-2.9.0.0.i386.rpm to eliminate
this problem.
However this particular rpm file is nowhere in the
internet. I have installed
compat-libstdc++-6.2-2.9.0.14.i386.rpm but I still get
the same error. I have ever copied /bin/cut to
/usr/bin/ without success.
The Installation instructions from the sun's site

Thank you in advance.
Allan Kamau.

This is a good idea.  It would also reduce the number of messages where
someone posts without subscribing, then posts again because they didn't see
the answer to their question.

RE: Tomcat crashes simultaneous more connection above 990+

[Randy Layman]

There are lots of other ways that you can crash Tomcat with
concurrent access, like using the JDBC-ODBC bridge.  I would advise you to
look at your application and assume that Tomcat is working just fine.  This
person was talking about high load (hundreds and thousands of concurrent
connection).

You set the max number of concurrent connections in the server.xml
file using the max thread variables.  The normal behavior (i.e. not under
extreme load) is for those extra connections to get 404s or have their
connections refused.

I didn't know.

I've tried with both of them.
With the noeapi, apache don't start.

I'm using Mandrake, so I guess that they use an enhanced version of
apache.

RE: Restarting Tomcat/Apache

[James Bromberger]

Hmm... similar to my message on Monday. However, I already have:

> java version "1.3.1"
> Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-b24)
> Java HotSpot(TM) Client VM (build 1.3.1-b24, mixed mode)

... on Solaris. one; 5 machines work fine, one does not shutdown at all (other than 
kill -9). Interestingly, the one that seems to be having trouble is the Solaris 8 
machine. The other 5 are all Solaris 2.6 (but all the *same* Sun JDK).

>>> [EMAIL PROTECTED] 08/15/01 03:37pm >>>
OK, found the problem.  I was using Sun's JDK 1.3.0_02.  Upgrading to JDK
1.3.1 has solved all the problems.

Thanks for the suggestions though.
