Then verify if that are independend processes:

Have a look at
ps ax --forest
to see if you have more than one parent process that spans vm's.

Kill single pid's and see if other processes/thread die to.

Hello


Again, sorry if i'm wrong, but if I do
killall java I got instantly 200 MB of memory free.
And yes, I'm running RH 7.2

Hi Keith (response inline)

This is supplementary info to Remy's: I think we've both got different

I've recently got 5 instances running on one 'lil-ole workstation, used for
personal development work.  My goal was to have multiple instances that I
could mess around with, without destroying the "live" (documentation,
examples, etc) server.

> how did u configure? Must i have more then 1 copy of tomcat?

No. I've installed tomcat (4.0.2) on my D: drive (should have said: Windows
2000 Pro, 2 hard-drives with multiple partitions - D: is apps, I: is
development) and the various instances on my I: drive:

CATALINA_HOME:
D:\tomcat\
CATALINA_BASEs:
i:\tomcat-servers\server01\
i:\tomcat-servers\server02\
i:\tomcat-servers\server03\
etc

Follow the instructions in running.txt for which directories to copy - I'm
at work just now (JRun ;-( ) but off-hand I think it's bin, conf, lib &
webapps.  Within /conf, you need to edit server.xml so the various ports
don't conflict.  Eg. if the CATALINA_HOME/conf/server.xml uses port 8080,
/server01/conf/server.xml could be 8081 for example.  There are three
locations in the server.xml which I edited - I don't have the file to hand
at the moment, but if you'd like a copy I can post it tonight/tomorrow.

Once you've created the directory heirarchy, and edited the server.xml
files, you should be able to start your new instances from the command
line/shell.  I'm lazy, so I just edited the catalina.bat files in
/server0x/bin/ to set CATALINA_BASE and CATALINA_HOME - again, if you'd like
a copy I'll post it tomorrow.

> I really dunno... pls help
>
>

Basically, most of the info is in running.txt from your Tomcat install.  I
found the only real gotcha was that I needed to renumber the ports.  Once
I'd got that sorted out the rest was plain sailing ;)

Best of luck, and if you're still stuck let me know and I'll post files.

Cheers
John

If you are using linux that's not right. What you see are threads 
not processes. Threads share the same memory, so the memory is

The default for the ibm and sun jdk is that the memory is limited
to some extend.

The limitation can be set through the option -Xms -Xmx for the jvm.

This just limits the heap size. What you can't restrict is the memory 
for the code and data segments. (To be honest I don't have a clear 
idea how memory is managed in a VM. E.G. if a class is loaded at 
runtime, will the code and static data be allocated on the heap of

enough classes or static data in the classes)

RE: Tomcat4 standalone keystore - existing private key problem

[Chris Campbell]

To answer my own question and perhaps help someone searching archives on
similar problems, the page at
http://www.cs.indiana.edu/~chiuk/security/ssl/jsse/certificates/ tells me
"Though sufficient for some tasks, a major deficiency of the keytool utility
is its inability to import a private key." Great. Looks like we will be
going through apache then.

This may solve your compile problems, but it will *not* solve runtime
problems.  In fact, it will cause mysterious runtime errors under 4.0 and
4.0.1 systems.

Your best bets:

* Use a development tool or IDE that understands how to build a
  compile-time class path for you.

* Use Ant to build your projects, as outlined in the Application
  Developer's Guide documentation that is included with Tomcat.

Trouble with IMG tag, servlets, and JSPs

[Ken Ramirez]

Hope someone can help:

I'm having a problem loading images from a JSP page when the page is
called from a servlet.  I'm performing a
forward from the servlet to the JSP, which then loads the images from a
subdirectory in the app's directory as follows:

/webapps/MyApp/*.jsp

/webapps/MyApp/images/*.img

The images are loaded from the JSP using the img tag as follows:



I've also tried src="/images/myimage.jpg" and this doesn't work.
However, if I call the jpg directly, everything shows up fine.
Of course in the real world, I need to get the forward to work so that I
can pass data from the servlet to the JSP.  I found
some information in the mailing list's archive regarding this problem
and someone suggested the following:



This does work, but it just seems odd that you would have to do this,
especially given the fact that there is a context entry for
the app in the server.xml.  Isn't the purpose of the Context entry to:

1.  Create and associate a Context object with the App and
2.  Establish the base path for the app.

Seems kind of redundent that you would have to again retrieve the
ContextPath yourself, when it seems that Tomcat should do 
this for us or the Browser should receive the problem path so that it
knows where to get the images and CSS files from.  Instead,
what is actually sent back to the browser is the following path for the
image:

"images/myimage.jpg"

Now what's interesting is that I looked in one of Tomcat's log files and
found the following exception for the images:

"StandardWrapper[/MasterMind:org.apache.catalina.INVOKER.theme]: Marking
servlet org.apache.catalina.INVOKER.theme as unavailable
2002-02-26 20:53:17 invoker: Cannot allocate servlet instance for path
/MasterMind/servlet/theme/Master.css
javax.servlet.ServletException: Wrapper cannot find servlet class theme
or a class it depends on ..."

And in one of the other log files, I found the following error:

127.0.0.1 - - [26/Feb/2002:20:53:17 -0500] "GET
/MyApp/servlet/images/myimage.jpg HTTP/1.1" 404 696


I'd like to get this to work without the hack I mentioned above.  Does
anyone have any suggestions?


Thanks,

Ken

ClassNotFoundException

[Ken Ramirez]

Hope someone can help:

I have a TOMCAT app containing a servlet as follows:

/webapps/MyApp/WEB-INF/classes/com/mycomp/MyServletClass.cl
ass

This class extends a base class that provides common functionality for
all of my apps, and is stored in:

/common/classes/com/mycomp/MyBaseServletClass.class  (which
extends HttpServlet)

Through some context information, the MyBaseServletClass receives the
classname of a class stored in my app's classes directory, 
which it is responsible for creating an instance of, using
Class.forName().  This is the path of the class to be created:

/webapps/MyApp/WEB-INF/classes/com/mycomp/MyOtherClass.clas
s

When the MyServletClass calls Class.forName, it fails with a
ClassNotFoundException, but if I move the MyServletClass 
to the MyApp/WEB-INF/classes path, everything works fine.

What gives?  I thought that Tomcat reads adds the classes directory for
all of the apps deployed in the server.xml 
(with Context info), which I defined as follows:

Re: Problem in starting up TOMCAT, please help.

You can also cd to your tomcat bin directory and type
catalina start

That will start tomcat in the same window, so that if it bombs you will see

Simple web.xml causes URL not to work

I am using Tomcat 4.0.2 standalone on Win2k Prof.

I have just a JSP file in my context

Without any web.xml, the URL
 http://localhost/Book/MySend.jsp
yields the page correctly.

But when I insert a web.xml under
webapps\Book\WEB-INF with the following content,
Tomcat cannot find the same URL (http://localhost/Book/MySend.jsp).

I am using the AJP 1.3 connector. I have uncommented the code from
server.xml.

I have added the context also to the server.xml file as follows

 

  
   


I tried editing the uriworkermap.properties file to add the entry as follows

# Default worker to be used through our mappings

default.worker=ajp13
#
# Sites to be redirected to Tomcat
#
/examples=$(default.worker)
/examples/*=$(default.worker)

/jisc/*=$(default.worker)
/vacodi=$(default.worker)
/vacodi/*=$(default.worker)
/chatservlet=$(default.worker)
/chatservlet/*=$(default.worker)


My tomcat files and the JSP files required to be run are on two different
drives on a same computer. Is there anything else to be done which I am
missing ?

Dear All,

I want to integrate IIS on win2k with tomcat 4.0.1

The redirector isapi_redirect.dll filter shows green with high priority. I
have set the docbase in the server.xml file  to the directory I have JSP
pages in. I was able to run these pages on port 8080 but are not working on
port 80.

What could be the problem?

Awaiting your replies,

RE: 2 instance of tomcat within 1 machine

[JBrawner]

John,

Could you please post the contents of you server.xml?  I'm trying to do
exactly what you've done with only 2 tomcat instances and am having
difficulty.  Also, I'm confused at which tomcat subdirectories needed to be
present in each CATALINA_BASE directory. The running.txt file mentions the
conf, logs, webapps, and work directories but you mention having to edit
the catalina.bat file (in the bin sub-directory) for each instance. So the
bin directory is needed to be copied as well?

Thanks,

Jason Brawner

Hi Keith (response inline)

This is supplementary info to Remy's: I think we've both got different
set-ups.

I've recently got 5 instances running on one 'lil-ole workstation, used for
personal development work.  My goal was to have multiple instances that I
could mess around with, without destroying the "live" (documentation,
examples, etc) server.

> how did u configure? Must i have more then 1 copy of tomcat?

No. I've installed tomcat (4.0.2) on my D: drive (should have said: Windows
2000 Pro, 2 hard-drives with multiple partitions - D: is apps, I: is
development) and the various instances on my I: drive:

CATALINA_HOME:
D:\tomcat\
CATALINA_BASEs:
i:\tomcat-servers\server01\
i:\tomcat-servers\server02\
i:\tomcat-servers\server03\
etc

Follow the instructions in running.txt for which directories to copy - I'm
at work just now (JRun ;-( ) but off-hand I think it's bin, conf, lib &
webapps.  Within /conf, you need to edit server.xml so the various ports
don't conflict.  Eg. if the CATALINA_HOME/conf/server.xml uses port 8080,
/server01/conf/server.xml could be 8081 for example.  There are three
locations in the server.xml which I edited - I don't have the file to hand
at the moment, but if you'd like a copy I can post it tonight/tomorrow.

Once you've created the directory heirarchy, and edited the server.xml
files, you should be able to start your new instances from the command
line/shell.  I'm lazy, so I just edited the catalina.bat files in
/server0x/bin/ to set CATALINA_BASE and CATALINA_HOME - again, if you'd
like
a copy I'll post it tomorrow.

> I really dunno... pls help
>
>

Basically, most of the info is in running.txt from your Tomcat install.  I
found the only real gotcha was that I needed to renumber the ports.  Once
I'd got that sorted out the rest was plain sailing ;)

Best of luck, and if you're still stuck let me know and I'll post files.

Cheers
John

RE: mySQL/JDBC/Tomcat4 documentation

[Steve Madonna]

Thanks everyone. I think I've got the "no sutible driver" thing fixed. Now
there's an SQL exception being thrown. Could be a programmer thing... I'm
going to get with our developers tomorrow to see if we can't get to the
bottom of this. Thanks again.

I actually found a pretty good page put together for OSX:
http://developer.apple.com/internet/macosx/tomcat2.html

It's actually pretty useful for anyone running tomcat.

Also the mm.mysql README was pretty helpful to:
http://sourceforge.net/docman/display_doc.php?docid=8968&group_id=15923


Thx again!

Re: IlligalStateException -- getOutputStream() has already been c alled for this response.

[Dmitry Nikelshpur]

I created a little test servlet to test includes and forwards in a clean 
environment.
The following block was used to test include/response within a servlet:

(nothing is "written" to the output buffer before the forward | includes)



//response.getWriter().write("test");

 dispatcher.forward(request, response);

 
 //  dispatcher.include(request, response);
 //  dispatcher.include(request, response);
 

//response.getWriter().write("test");



1) Running with forward uncommented:
  I now get a different error, for the first time! -- 
 java.net.SocketException: Socket Closed
 The chart displays fine in the browser.

2) Running with one or two includes uncommented:
I get java.lang.IlligalStateExeption: getOutputStream() has already 
been called for this response.
I get garbage in the browser

3) Running with the top write, and forwards uncommented:
 The chart is displayed properly, AND I get a message box saying 
that the document contained no data!
 I get java.lang.IlligalStateException: getWriter() has already been 
called.

I am "beginning" to think that this is expected behavior according to 
servlet specs (which I d/loaded and promissed myself I'd read :)
Even if this is the case, there must be a way to include charts, or 
combination of charts,  and other stuff on the same page...it's not like 
it's never been done before...


Regards!

Dmitry

Re: J2EE, JSP, SERVLETS

[Cathy Ooi]

Quite right. As I'm involved in both development, deployment and maintenance,
portability and security are key issues. Apache does support ASP, I think, but I
don't quite trust that if I can help it. What about Perl? I still like to use it
for small, quick jobs.

There are a couple of reasons to pick JSP. I usually tell bosses that
we use java because it is easy to replicate across multiple hardware as
the demand for the app grows (They love thinking about growing demand).


Security is an issue too, especially with M$ products (not sure about
PHP). How many viruses have we seen in the past few years effecting
IIS, Exchange and NT?

There are some good whitepapers comparing JSP to other technologies on
the JavaSoft site. here's one:

Re: mySQL/JDBC/Tomcat4 documentation

[丁辉]

The installation process is very simple.you simply copy the mm.mysql-2.0.4-bin.jar to 
somewhere in your computer, and add that JAR file into system's CLASSPATH.
I think your problem is not caused by CLASSPATH, maybe it's  the problem of 
initilizing the MYSQL JDBC driver.

RE: Servlet POST results in 404 error

[John Wadkin]

keith,

Yeah - Randy Layman solved it. The servlet mapping was setup to servletname/
instead of servletname/* The answer's obvious now! Whenever the servlet
created a URL like:

/servletname/stringofnumbers

It stopped working cos that particular URL pattern wasn't mapped. It just so
happens that this only occurs when the servlet uses doPost, hence me
thinking it was a POST problem!

Re showing you the post method - I'd have trouble finding it :) The servlet
is incredibly complex - loads of classes. I'm a pretty naff Java programmer,
which doesn't help! I've only seen parts of the code - frightening stuff!
The servlet is an electronic Personal Development Planning (PDP) tool called
LUSID. It allows the user to record experiences and achievements, perform
skills audits, and plan goals and activities. Pages are create in an XML
language (lusidml) which the servlet then parses. Everything's stored in an
Oracle database. It's a bit rough around the edges and the interface is
pretty poor from a HCI perspective but otherwise it's pretty good.

Thanks,

John

That old tomcat 4.0.2 - xerces.jar file problem one more time...please

[Drew Cox]

I'm sorry guys.  I've searched the archives, really.  I have seen a bunch of
seemingly relevant posts and tried some of their recommendations.  But I
can't get this to work.  Here's the deal.

Our webapp includes xerces.jar in the web.inf/lib directory.  This works
fine on Tomcat 3.1 (our prod version) and 3.3a (our new prod version if I
can't get this sorted).

On 4.0.2 I get the following error in the tomcat logs, apparently when
trying to compile a JSP:

classloader/version conflicts with the xerces.jar in the

xerces.jar around into all of the other libs in tomcat to no avail.

If I remove our webapp's xerces.jar, things work fine.  This is a reasonable
workaround, but what if I really needed different versions of the library
available to different apps?  I'm sure there is a simple way to make this
work, please help the terminally bewildered to get this working.

configuring logger, given Tomcat's daily log filename changes

Yes, but the name of the tomcat log file changes daily --- is there some way 
to set up the logger to automcatically deal with these name changes ?

I realize this thread has run outside of the realm of Struts, and should 
really be appearing in the Tomcat mailing list now, so I'm sending it there.

I think that if you use
if(servletContext.getInitParameter("CONFIG_FILE") == null);
etc.

you'll get what you want. That method is doc'd in jdk 1.3.1, but NOT in my
"Enterprise in a Nutshell"

Re: Tomcat 4.0.2 and ejb-local-ref

[Nicolas Moldavsky]

It's Redhat 7.2 on Intel with the .tar.gz installation:

When the server boots up there is no message saying it is linking the the

following message:

Troubles with the list: 

Tomcat 4 + Apache + Linux + multiple virtual name-based hosts + separate instanc

[Neo Thinker]

I have been working on this for a LONG time. There's got to be some
smart guy out there with the answer.

I would like to do this:
On one Red Hat Linux box,
run one instance of Apache,
with multiple name-based virtual hosts,
with a separate instance of Tomcat 4 for each virtual host.

I have gotten the virtual hosts to work without tomcat. I have gotten
multiple tomcat servers to work as standalone. I have gotten 1 virtual
host to work with an instance of tomcat, the other virtual hosts did
not have tomcat (because of a "Web-application not yet deployed" error
when I try to give a WebAppConnection for each virtual host).

If anyone has knowledge of how to do this, please let me know. I am
creating new website so I can even use different technology if
necessary. I am thinking that I can not do this (at least not with
mod_webapp).

Help, please.

Thanks Sriram for the suggestion of loading the properties file from

RE: IlligalStateException -- getOutputStream() has already been called for this response.

[KC Berg]

How are you doing the includes? Also when you are using a forward in a
servlet you can not print anything to the output buffer before you use the
forward. Because once the output stream has been sent to the browser the
server can no longer forward that stream to another servlet.

Subject: IlligalStateException -- getOutputStream() has already been

Hello everyone.

I had posted a similar message before, but either did not get replies or 
missed them.

I am using a JavaBean in a JSP page. This bean draws charts and graphs 
depending on supplied data...

When I call the JSP page directly from the browser, the graph displays 
properly, and no error messages are dumped to catalina.out.

When I have a servlet forward to the JSP page, the graphs display 
properly, but I get a message in catalina.out: 
java.lang.IlligalStateException: getOutputStream() has already been 
called for this response.

When I have a servlet include the JSP page, I get garbage in the 
browser, and the same message in catalina.out, 
java.lang.IlligalStateException: getOutputStream() has already been 
called for this response.

I had seen posts regarding this error, and believe that I saw something 
in the bug databasee, but still no solution.
Is this behavior 'normal?' for JSPs / Servlets?

The bean that I am using to create the charts is called jspChart, and is 
at:  http://www.javaside.com/u_jspchart.html
This URL contains a sample JSP page, so any servlet that includes / 
forwards this page should produce above results.

I would apprecieate it if you could BCC me in your replies, to make sure 
I get the message.
Also, if you have any other solutions for creating charts/graphs 
dynamically, with the ability to include/forweard from servlets, I'll be 
more than pleased...

Thanks in advance!

RE: servlet-mapping problem

OK -- I'm having a related problem:

I can hit my servlet with the following httpd.conf and web.xml file setup
with these two URLs:

http://hostname:8080/s2/sb/

And

http://hostname/SiteBlocks/sb/


>From within the servlet, I am trying to reconstruct the URL. I am using the

Unfortunately, the URL this produces is either:

http://hostname:8080/sb or http://hostname/sb,

This is basic stuff.  It should work.  What URL are you using to invoke the
servlet?  With no mapping the URL would be http://server/servlet/warservlet.
If your mapping is

  /blah

then the URL would be http://server/blah.  Restart Tomcat to be sure your

The way to avoid this startup time is to not restart Tomcat at all :-).

Tomcat includes a Manager webapp that includes the ability to dynamically
install, reload, and remove individual webapps, without ever having to
restart Tomcat itself.  The commands are simple HTTP requests with query
string parameters, so it is really easy to script.  More info:

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

In the nightly builds of Tomcat 4, you will also find that we've included
some custom tasks for the Ant build tool so that you can install, reload,
and remove webapps directly from your build.xml file.  It takes a second
or two to execute these.

RE: many java processes

also tomcat will only open as many pid's/thread's as is specified in your
server.xml

maxProcessors="75" part of the connector params. 

the above is the default. Running "top" may make it look like a lot of stuff
is running but if you look at the memory and CPU utilization of the pid's
you'll notice they are very low. Also the number of pid's will change as the
number of concurrent users to your system increases or decreases.

   I am afraid that if a put a few java domains on the server the java
processes will begin to go through the roof.

Yes. On login, a bean is put in the user's session with name, whether

All,

TomCat 4.0.1
Apache 1.3
mod_WebApp
Solaris 8

I have a servlet that returns a 404 error whenever a POST is sent. GET works
fine. The servlet uses sessions - not sure if this has anything to do with
it. My server.xml just defines a context and a logger. The web.xml has a
servlet name and mapping, nothing more.
The servlet was originally written for JServ - could this have something to
do with it?

There's nothing in the logs.

I'm not a servlet programmer so I have no ideas!

Any suggestions??

Thanks,

John

Re: servlet-mapping problem

[Dave Ferguson]

This is basic stuff.  It should work.  What URL are you using to invoke the servlet?  
With no mapping the URL would be http://server/servlet/warservlet.  If your mapping is

  /blah

then the URL would be http://server/blah.  Restart Tomcat to be sure your changes take 
effect.

Re: J2EE, JSP, SERVLETS

[August Detlefsen]

There are a couple of reasons to pick JSP. I usually tell bosses that
we use java because it is easy to replicate across multiple hardware as
the demand for the app grows (They love thinking about growing demand).


Security is an issue too, especially with M$ products (not sure about
PHP). How many viruses have we seen in the past few years effecting
IIS, Exchange and NT? 

There are some good whitepapers comparing JSP to other technologies on
the JavaSoft site. here's one:

RE: Servlet POST results in 404 error

Marvellous - spot on Randy. I'd just used servletname/ as the mapping. No
idea why. Obvious now that it won't work. I guess I'll have to lay off the

It sounds like the servlet is trying to use PathInfo (extra
characters beyond the real servlet's name for parameters).  In your web.xml
you probably want to make your URL mapping something like /servletname/* so
that every URL that starts with servletname is called for that servlet.

RE: Internal Server Error with METHOD:POST

[Reynir Hübner]

Hi, 
there are few possibilities ... 

1. that you need to restart tomcat to get the servlet loaded. 
2. case sensitivity, is the taskserv in correct case ? 
3. is, that you're servlet is not compiled. (you only have .java under
WEB-INF/classes)

sounds like one of those, but it could always be something else.

hope it helps

Re: High startup and shutdown time of tomcat 4

[Wolfgang Stein]

Hi,

the startup time will even increase if you enable a SSL-connector.
But you don't have to restart the whole tomcat to restart
an application (compared with TC 3.2, don't know 3.3),
if you use the manager app instead.

You can also enable dynamic servlet reloading during development.

I suppose the startup time is a tribute to the better
catalina architecture, new features and servlet 2.3 spec conformity.

I also removed all unused applications (e.g. examples, doc ...)
to reduce the start up time. 

I didn't notice a slower shutdown.

Gruss,
Wolfgang

RE: Servlet POST results in 404 error

[John Wadkin]

The servlet is an application that has numerous modes. If I want to create a
new user of the app, I type the URL:

servername/webapp/servletname?mode=19

I enter all the details of the new user, and the servlet "posts" this info -
a get would show password details in the URL. It then creates a page:

servername/webapp/servletname/stringofnumbers

Informing me of the outcome of the attempt to create a new user - i.e.
success or failure. At this point it fails with a 404. The logs give exactly
the same info. I've checked everything I can think of and changed the
DocumentRoot in Apache to the webapps/webappname directory. No joy! As I see
it there are two possibilities:

I've misconfigured TC and/or Apache - but how?
The servlet implements or does something that is no longer supported in
TomCat and/or the latest servlet API.

I'm at a loss!

Thanks,

John

I had some JSP pages that worked on Netscape but not Tomcat. It 
turned out that Tomcat wanted to see a "=" separating the 
name=value pairs. From your example above, it looks like you're 
just trying to pass some numbers so you don't actually need

Simply adding the "=" fixed it for me. Now, sometimes I'll add a

IlligalStateException -- getOutputStream() has already been called for this response.

[Dmitry Nikelshpur]

Hello everyone.

I had posted a similar message before, but either did not get replies or 
missed them.

I am using a JavaBean in a JSP page. This bean draws charts and graphs 
depending on supplied data...

When I call the JSP page directly from the browser, the graph displays 
properly, and no error messages are dumped to catalina.out.

When I have a servlet forward to the JSP page, the graphs display 
properly, but I get a message in catalina.out: 
java.lang.IlligalStateException: getOutputStream() has already been 
called for this response.

When I have a servlet include the JSP page, I get garbage in the 
browser, and the same message in catalina.out, 
java.lang.IlligalStateException: getOutputStream() has already been 
called for this response.

I had seen posts regarding this error, and believe that I saw something 
in the bug databasee, but still no solution.
Is this behavior 'normal?' for JSPs / Servlets?

The bean that I am using to create the charts is called jspChart, and is 
at:  http://www.javaside.com/u_jspchart.html
This URL contains a sample JSP page, so any servlet that includes / 
forwards this page should produce above results.

I would apprecieate it if you could BCC me in your replies, to make sure 
I get the message.
Also, if you have any other solutions for creating charts/graphs 
dynamically, with the ability to include/forweard from servlets, I'll be 
more than pleased...

Thanks in advance!


Dmitry

Internal Server Error with METHOD:POST

[fusterjj]

Hello everyone, 
I am trying to do a simple servlet with an html form using the POST method. The html 
form is just a simple input form where the user enters 4 fields of data. The HTML 
invokes the taskserv, wich is the servlet with the post method and the driver 
connection to mysql database in order to insert the data in the database. The problem 
is that I am getting an Internal Server Error which says:
Cannot allocate servlet instance for path /servlet/taskserv; however the servlet is 
inside the WEB-INF directory and inside the CLASSES folder, so it should not have any 
problem to find the class. I have changed the code a couple of times but I am getting 
the same error. Does anyone know why is this happening?? Is there has to be with  my 
Tomcat configuration or the web.xml or the code??? 
I would really appreciate if you help me. If you are willing I can send you the code 
and the Exception report to make it easier.

 Thank you all!!!

I had some JSP pages that worked on Netscape but not Tomcat. It 
turned out that Tomcat wanted to see a "=" separating the 
name=value pairs. From your example above, it looks like you're 
just trying to pass some numbers so you don't actually need 
the "=" (informationally), but Tomcat does to pass it on through 
the request.

Simply adding the "=" fixed it for me. Now, sometimes I'll add a 
label as the value, like: thedata=a_label, which is a visual 
convenience but ignored by the backend.

servername/webapp/servletname/stringofnumbers

The log for TomCat shows a valid URL - i.e. I can't see anything wrong with
the URL. Worryingly, if (after I get the 404) I type a / after the string of
numbers and press "Enter", the contents of the post (inc. passwords) appear
in the browser as a 501 error!
The rest of the servlet works fine - it's just the post method for some
reason.

I think it might be relevant to say that the servlet was written and
installed in the mid-nineties. Nothing major has been done to it since... My
Uni has agreed to "test" if the servlet will work on a more modern platform,
amongst other things. I've only just started working with servlets so I'm
not aware of the historical context - e.g. major changes between JServ and
Apache, changes in the Java and/or Servlet spec's.

Thanks,

John

did you define the doPost method in your servlet?

if not add:

...
public void doPost(HttpServletRequest request, HttpServletResponse response)
{
   doGet(request, response);
}
..

Re: SSL Client authentication with standalone Tomcat

This part should read:
The client browser scans his (previously imported) client certs
for a matching cert issuer/signer, fills / pops up a choice dialog
box to select a client cert from, 
and sends (?) the users selection back to the server.

This choice box was usually empty in MS IE. Read my previous
posting "Any success with Tomcat 4.0.2 and client
certificates in MS IE ?"

RE: Servlet POST results in 404 error

[Randy Layman]

Is it possible that your servlet is seeing the POST, processing it,
and then sending a redirect to a non-existent page?

You might want to check the Tomcat and IIS/Apache/iPlanet logs to
find out what URL is being used to get the 404, that way you will know how
Tomcat or the connector is trying to interpret your request.

RE: Servlet POST results in 404 error

[PELOQUIN,JEFFREY (Non-HP-Boise,ex1)]

John,

Things to look for:

1: Is the post service defined in your servlet
2: Does the post service contain any code
3: Is apache configured to allow use of the post method, if I recall out of
the box it does not
4: Use the Netscape Browser if you are not already.  It returns more error
information than IE

All,

TomCat 4.0.1
Apache 1.3

Solaris 8

I have a servlet that returns a 404 error whenever a POST is sent. GET works
fine. The servlet uses sessions - not sure if this has anything to do with
it. My server.xml just defines a context and a logger. The web.xml has a
servlet name and mapping, nothing more.
The servlet was originally written for JServ - could this have something to
do with it?

There's nothing in the logs.

I'm not a servlet programmer so I have no ideas!

Any suggestions??

Standalone Tomcat SSL Cipher Suite Configuration

[Boyd, Garth]

Is it possible to configure a standalone Tomcat installation  to
negotiate from an administrator provided cipher suite list?

Other containers do allow you to configure what cipher suites
are available for negotiation (websphere for example). I have 
searched high and low and have not found anything to indicate 
that this is configurable for standalone Tomcat.

Can someone prove me wrong? Please?

Thanks in advance,

The trigger code has been removed since then, so the problems should be
fixed in the next Tomcat release (you can check with a nightly build).

RE: problem in using

[Nicolas Silberzahn]

Sorry, this is not an answer, just a word to say i face the same problem.

With TomCat 3.3, all where ok.
Installed 4 this morning, And when referencing a bean from a jsp, i get:


org.apache.jasper.JasperException: Unable to compile class for JSP

An error occured between lines: 72 and 83 in the jsp file: /wapstate.jsp

Generated servlet error:
D:\TomCat4\work\localhost\offsyncwap\wapstate$jsp.java:152: Class
org.apache.jsp.WPKDoc not found.
 WPKDoc myDoc = (WPKDoc)session.getAttribute("myDoc");
 ^


It does not find WPKDoc class (which is in the WEB-INF/classes directory)
You may note I don't use the  syntax, but i tested it: it gives
the same problem since it produces a .java file in the work directory with
the same rpoblem...

Re: problem in using

I had the same problems using tomcat 4.0.2, and apache
1.3.22 on win2k.  In fact tomcat couldn't find any of
my classes.  This only occurred using mod_jk, but
eventually i got it to work.  It is strange, but
here's how i got mine to work.  If you are using
mod_jk, try commenting out the line regarding
additional classpaths in your workers.properties file.
 Restart tomcat and apache.  It still won't work at
this point.  Then uncomment the line and restart both
tomcat and apache.  I think by commenting out the line
and restarting apache and tomcat, it forces them to
reload settings?  Not sure though.  

Also make sure you have the directive JKMount
/servlet/* ajp13
in httpd.conf file.

everytime restarting tomcat for small changes is very wierd stuff :-(

I'm using tomcat 4.0.2 (the latest stable version released on 11 feb)

Tomcat tutorial searched

[Thomas Stiller]

I am searching a tutorial/introduction covering
the configuration of Tomcat (3.* or 4.*)
setup of servlets and JSPs in the server.xml.

I am NOT (!!) searching a tutorial for
developing servlets/JSP in general

Is there a good tutorial out in the internet 
with simple samples (helloWorld) ?

Thx

Tomcat 4.01, IIS, and isapi_redirector.dll

[Thad Humphries]

I have found several sites for integrating Tomcat 3.2.x with IIS using
isapi_redirect.dll.  I find some for integrating Tomcat 4.01 with IIS
using isapi_redirect.dll.  The latter require creating
workers.properties and uriworkermap.properties (and maybe other things)
that aren't part of Tomcat 4.01 on UNIX (but were in 3.2).  Also, the
Tomcat 4.0 tree has a binary isapi_redirector.dll (**not**
isapi_redirect.dll).  Is *this* the warp connector?  How do I setup
Tomcat 4.01 and IIS to use this connector?  Is it a simplier setup than
3.2 was?

Servlet POST results in 404 error

[John Wadkin]

All,

TomCat 4.0.1
Apache 1.3
mod_WebApp
Solaris 8

I have a servlet that returns a 404 error whenever a POST is sent. GET works
fine. The servlet uses sessions - not sure if this has anything to do with
it. My server.xml just defines a context and a logger. The web.xml has a
servlet name and mapping, nothing more.
The servlet was originally written for JServ - could this have something to
do with it?

There's nothing in the logs.

I'm not a servlet programmer so I have no ideas!

Any suggestions??

Thanks,

John

Instead of accessing the fileSystem, try the following instead:

InputStream inputStream = 
getServletContext().getResourceAsStream("/WEB-INF/classes/pro.properties");
Properties properties = new Properties();
properties.load(inputStream);
inputStream.close();

This will let you later bundle the whole application as a war file (similar to zip or 
tar files, and created with the jar command).
Also, you won't have to change the CONFIG_FILE parameter when you move your web 
application to some other folder.

That's because this context has been added after Tomcat has been started. The 
information about this newly added Context is not stored anywhere.

If you wish to do this, then include a section in %CATALINA_BASE%/conf/server.xml

It could be something like the following:

Properties file declaration

[Ursula Pieper]

Hi, 

my servlets need to access a properties file 
(/var/tomcat4/webapps/application/WEB-INF/classes/pro.properties). 

I tried to get the parameter to read properly by adding parameter entries 
at different location. so now:

My server.xml entry looks like this:



CONFIG_FILE
/var/tomcat4/webapps/application/WEB-INF/classes/pro.properties



and the web.xml:

/application
application


CONFIG_FILE
/var/tomcat4/webapps/application/WEB-INF/classes/pro.properties



This entry gets recognized at tomcat startup:
in catalina.out: 
XmlMapper: org.apache.catalina.core.StandardContext.addParameter( CONFIG_FILE, 
/var/tomcat4/webapps/application/WEB-INF/classes/pro.properties)

The call for is in the servlet looks like this:

init(ServletConfig config)
throws ServletException
{
super.init(config);
try
{
 configPrefs = new Properties();
 servletContext = config.getServletContext();
 if ( config.getInitParameter("CONFIG_FILE") == null )
 throw new ServletException( "No CONFIG_FILE param" );
...


and I am getting the following error message:
javax.servlet.ServletException: No CONFIG_FILE param

Can anybody help me straighten this out?

I am new to this and want to get this application to run. I am just now 
learning java and tomcat, so please excuse my probably trivial question. 

I am running 
Tomcat 4.0.1
jdk1.3.1
on redhat 7.2

Thanks a lot!

Ursula

You are asking Tomcat to deploy the web app located at /myfoo as the ROOT application. 
This is the application that's accesible at http://localhost/
Instead, replace the path="" with path="/foobar" and start Tomcat again.

Your app should now be accessible at http://localhost:8080/foobar/

If HelloWorld is a servlet, then it must be listed in the file at /foo/WEB-INF/web.xml

Just keep in mind one important thing.
$TOMCAT_HOME/webapps represents the appBase="webapps" item of the
default Context attribute.

Where did yu create it, under $TOMCAT_HOME/webapps ?

Not sure of what yu did.. means appBase="/myfoo" ?

Ooopps AFAIK modifyin' CLASSPATH doesn't intend any thing for Tomcat
since it builds with it's ClassLoader it' own environnement. The only
way to set a CLASSPATH for it is to modify th ecatalina.sh
UNIX script...

With the server/web.xml not modified, the call would be
http://localhost:8080/servlet/HelloWorld

Can Tomcat 3.3 be chroot'ed, Should it be ?

[M Man]

Hi All

I've got Apache 1.3.22 and Tomcat 3.3 working fine on Solaris 8.
I can even get Apache running chroot'ed, but I can't get Tomcat too.

I've looked all over the net and not found a HOW-TO.
I found one document that said Tomcat could NOT be chroot, (didn't 
understand the reason's why, I'm not a Java programmer).

So is can it be chroot'ed and if so how ?.

I found a few documents that said the security now in Apache/Tomcat means 
that running them chroot'ed is not really required, is this true ? (hope so, 
it would save a lot of effort :) )
Any document pointer's as to why this imaybe true now would be helpful ?

Thanks in advance

Fwd: Unable to use RequestDispatcher.forward() for HTML pages when in Tomcat 4

[Sriram Narayanan]

Hello all,

I'd posted to this list a few days ago asking for help on this problem.

On the computer where I run tomcat and faced the RequestDispatcher problem, I've 
started to get JIT errors instead. I've also been getting a 
lot of "Illegal Operation" messages by Windows on the same computer for the past few 
days.

I got a chance to check this problem again today on another computer, and everything 
ran just fine.

So I guess I have to either reinstall Windows NT, and maybe even get the RAM on my 
computer checked.

Thanks everybody for helping me out.

By the way, I tried the following, and both worked:

getServletContext().getRequestDispatcher("/index.html").include(request,response);

and separately,

getServletContext().getRequestDispatcher("/index.html").forward(request,response);


Thanks again.

Sriram

Subject: Unable to use RequestDispatcher.forward() for HTML pages when in Tomcat 4
Date: 2/21/02 8:06:31 PM

Hello all,

I am able to use the RequestDispatcher forward control from one JSP page to another. 
However I am unable to forward to HTML pages.
>From what I read in the Servlet API spec (there's an example for /garden/ etc) and 
>the docs for RequestDispatcher(), one should indeed be 
able to forward to HTML pages

Here's what I have in my JSP:

<%getServletContext().getRequestDispatcher("/html/authhome.html").forward(request,response);%>

And here's what I found in the generated JSP page:

--- beginepartial quote -
application = pageContext.getServletContext();
config = pageContext.getServletConfig();
session = pageContext.getSession();
out = pageContext.getOut();

// begin [file="/notauthorized.jsp";from=(0,2);to=(0,92)]

getServletContext().getRequestDispatcher("/html/authhome.html").forward(request,response);
// end
// HTML // begin [file="/notauthorized.jsp";from=(0,94);to=(1,0)]
out.write("\r\n");

// end

- end partial quote 

Could someone please point me to what it is that I'm doing wrong ?

I have only the Servlet API spec with me, and not the JSP spec, which I have not been 
able to download yet (Internet connection problems)

Thanks,

Sriram

Re: Tomcat: Servlets in another directory

[rsequeira]

Editing the classpath isn't advisable. Leads to various problems. Also are
you using unix or windows? Check your docBase. Is "myfoo" under the webapps
directory? If it is, then you do not require the leading "/". Also check
the web.xml for mappings to HelloWorld.
Thanks.

Subject:  Tomcat: Servlets in another directory

Hi.

I would like to serve my servlets in another directory
(not in $TOMCAT_HOME/webapps/examples/WEB-INF/classes).

+ I created a directory called '/myfoo'.
+ I changed $TOMCAT_HOME/conf/server.xml:

+ I compiled 'HelloWorld.java' into '/myfoo'
+ I changed startup:
set CLASSPATH=%CLASSPATH%;/myfoo

But when trying to access: http://localhost:8080/HelloWorld ,
I get a '404 Error'.

What am I doing wrong?

Regards and thank you very much.

Re: problem in using

[Harry Keller]

I had problems with using beans with Tomcat 4.0.  Sometimes they would
work -- sometimes not.  I never got tomcat to recognize two properties in
the same bean.  Eventually, I abandoned the bean approach as unworkable with
tomcat.  If anyone has a reliable solution, I'd really like to know about
it.  For now, I just @include the java source in my JSP files.

Hopefully,
Harry

[Eduardo Godoy]

Hi,
I´m using tomcat 4.0.2 and I want to add a new context, without a war file ... so 
I used

and tomcat return 
OK - Installed application at context path /ucrm

but ... If I reboot the server ... I lost the context ... 
(I don´t have this problem with others context, where I use a war file to deploy)
Any Idea?

Eduardo.
