Out of memory

[Yun Yang]

Hello,

I am using Tomcat5.0.28. When I try to run my web application, I got
this message:

exception
 
javax.servlet.ServletException: Servlet execution threw an exception

root cause

java.lang.OutOfMemoryError

 
How can I solve this problem? I tried to uninstall tomcat5 as service
using service.bat remove and tried to reinstall it as service in
Windows XP. How can I add option like -xmx512M into service.bat? Or
How can I increase the heap size?

I added this statement into Catalina.bat set JAVA_OPTS=-Xmx512m. It
works. But When I run tomcat5.0 as server it still does not work.

 

Thanks,

 

Yun Yang

Tomcat 5.0.28 and JPDA

[Andy Yang]

Hi there,

I'm just trying to start up a standalone instance of
Tomcat 5.0.28 in a Windows XP environment
(non-service) with JPDA and I'm getting the following
error when I execute: catalina.bat jpda run

Error [2] in connect() call!
err:: No such file or directory
Socket transport failed to init.
Transport dt_socket failed to initialize, rc = -1.
FATAL ERROR in native method: No transports
initialized

I'm getting this while running Tomcat with JDK
1.4.2_04. The full startup command is:

c:\j2sdk1.4.2_04\bin\java   -Xdebug -Xrunjdwp:tra
nsport=dt_socket,address=8000 ,server=y,suspend=n 
-Djava.endorsed.dirs=D:\jaka
rta-tomcat-5.0.28\common\endorsed -classpath
c:\j2sdk1.4.2_04\lib\tools.jar;D:
\jakarta-tomcat-5.0.28\bin\bootstrap.jar
-Dcatalina.base=D:\jakarta-tomcat-5.0
.28 -Dcatalina.home=D:\jakarta-tomcat-5.0.28
-Djava.io.tmpdir=D:\jakarta-tom
cat-5.0.28\temp org.apache.catalina.startup.Bootstrap
 start

Has anyone come across this? I was originally running
Tomcat using JDK 1.5 - but ran into similar problems
trying to get debug working. Would there be any
compiled artifacts hanging around that might be
throwing Tomcat off?

Could a software firewall be interfering with things?

Thanks for your time,
Andy

email from tomcat

[Jenny Yang]

Can anyone tell me how to use email from tomcat?

I was given that task to do before my summer
internship starts.  I did numerous google searches,
and checked out Tomcat books at the bookstore.  I
haven't found anything helpful besides this list.

Thanks.

Minimum Memory Requirement for TC 5.0.x

[Yang Xiao]

Hi all,
What is the minimum memory requirement to run TC 5.0.x in a Linux
environment? or is there such a thing? I can't find it anywhere, which
is kind of amusing.
Many thanks,

Yang

Strange problem

[Yang Xiao]

Hi all,
I'm running Tomcat 5.0.30 on FC2 with SUN 1.4.1_02 jdk
I'm having this strange problem, I can not access any jsp or servlet
pages using a browser, it seems to be  timing out, but telnet to the
port tomcat is listening then type GET ... works. I can see the
directory structure and regular html pages works fine, any ideas?
Also, there were no error messages in the log either, a tcpdump
indicates the server terminates the connection right after the  http
requst was sent from the browsers (I tried both IE and firefox)

Many thanks!!

Question about memory

[Yang Xiao]

Hi list,

I have 3 Tomcat 5.0.19 instances running with Apache 2.019 and JK2.

I did a simple load testing with JMeter last night and stopped it just
before I went home, so right now there's no incoming request whatsoever, but
TOP still shows heavy memory usage and swapping, it looks like even though
the load has subsided, Tomcat has not released the memory, what can I do
except restart the Tomcat instances to release the memory?

I'm not sure if this is a valid question, so I apologize if I seem to be
lack of some basic understanding of how things work.

Thanks in advance.

Also the tomcats are started with -Xms64 -Xmx256

Just a silly question, but don't you also need to perform some additional
production configuration in your web.xml by setting fork equal to true and
developement equal to false.  It explains it on this page here:

http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jasper-howto.html#Production
%20Configuration

I made some similar modifications and I noticed that tomcat started to
release the memory when the server was not as busy.

RE: where to define path to workers2.properties

[Yang Xiao]

Hi,
By default it's your ${serverRoot}/conf dir, but you can do this
LoadModule jk2_module modules/mod_jk2.so
JkSet config.file /usr/local/apache/conf/workers2.propertie

hi tomcat-users

i have installed and running apache/tomcat/jk2 on a linux-box. in the 
meantime i updated apache and because i use a directory with 
version-number, the path to the apache-rootdir changed.

now my mod_jk2-module searches the workers2.properties configfile still 
in the old apache-directory. can i anywhere define the path to the 
workers2.properties file?

i found some examples for windows where the path is written to the 
registry, but no example for linux

thanks and greetings

  Just a silly question, but don't you also need to perform some
 additional
  production configuration in your web.xml by setting fork equal to true
 and
  developement equal to false.  It explains it on this page here:

  I made some similar modifications and I noticed that tomcat started to

  Hi list,
 
  I have 3 Tomcat 5.0.19 instances running with Apache 2.019 and JK2.
 
  I did a simple load testing with JMeter last night and stopped it just
  before I went home, so right now there's no incoming request whatsoever,
 but
  TOP still shows heavy memory usage and swapping, it looks like even
 though
  the load has subsided, Tomcat has not released the memory, what can I do
  except restart the Tomcat instances to release the memory?
 
  I'm not sure if this is a valid question, so I apologize if I seem to be
  lack of some basic understanding of how things work.
 
  Thanks in advance.
 
  Also the tomcats are started with -Xms64 -Xmx256

Hi,
Everything looks fine, do you have the AJP connector defined in the
server.xml file?

hi all...

this is my first question on this list so please be gentle...

i'm trying to use a servlet that talks to a j2me application on some cell
phone. the thing is when i try to compile the code on the server machine
(i put it under the tomcat's servlet examples) i get an error that i have
the clases in the HTTP servlet package missing. i found them (after
downloading them again) in the server's java source. my question is where
should i put them so the compiler can finde them and compile the
servlet? it turns out there are a lot of servlet src folders..

thanks

I fooled myself - forgot to clear-down browser cache after doing some
fiddling. :/  Still not working

I am using mod_jk2 - and as far as I can tell apache and tomcat do talk,
for example if I move my test.jsp to $CATALINA/webapps/ROOT and browse
to http:/test.int/test.jsp it works, so I guess that something is wrong
with the context for test.int ??? And also, the 404 is from tomcat, so
apache is handing over to tomcat for .jsp but tomcat can't find them.

   Hi all,
   
   I'm going nuts trying to do something pretty straight forward, namely

   keep the default tomcat stuff at port 8080.
   
   I've read every howto I can find and can only get one or the other to
   work. My confusion seems to revolve around the context element in
   server.xml.
   
   What I want is to be able to do is point at http://localhost:8080 and
   see the tomcat welcome page. I then want to point to
   http://test.int/test.jsp and see the .jsp output.
   
   The test.jsp file resides in /var/www/html/beta but I keep getting
   tomcat 404 error, so I guess it's having problems locating the .jsp
and
   therefore suspect my contexts are incorrect.
   
   I would be grateful is someone could have a look at my server.xml and
   hhtpd.conf snippets and enlighten me.
   
   Regards.
   
   
   
   this is how my server.xml is:
   
 Host name=localhost debug=0 appBase=webapps
  unpackWARs=true autoDeploy=true
  xmlValidation=false xmlNamespaceAware=false
   
  Logger className=org.apache.catalina.logger.FileLogger

   unpackWARs=true autoDeploy=true

   test.jsp resides --
   
   Logger className=org.apache.catalina.logger.FileLogger
   directory=logs  prefix=test_int_log. suffix=.txt
   timestamp=true /
   /host
   
   and the relevant bit of httpd.conf:
   
   VirtualHost *
   ServerName test.int
   ServerAdmin [EMAIL PROTECTED]
   DocumentRoot /var/www/html/beta
  Location /*.jsp
   JkUriSet worker ajp13:localhost:8009

   I have also tried using the workers2.properties file instead of the
   JkUriSet by entering
   
   [uri:test.int/*.jsp]
   worker=ajp13:localhost:8009
   
   but it dosen't seem to make much difference

Virtual host setup

Hello ,

I want to setup several virtual hosts in a single Tomcat.
I want to use Name-based approach. For this approach, several virtual
hosts share a single IP address.
So I have to bind different web services to same address? for
instance, the address of www.1.com and www.2.com is same and point to
the same Tomcat server.
Any detailed documents?

Still no luck. I'm basically trying to do exactly the same thing
that the jsp-examples/checkbox is doing and I can't get Tomcat
to recognize my UserData.class file. I've tried placing my UserData.class
file in every location possible, and no luck. My next step will be
to downgrade to Tomcat 4 so I can at least try out the examples that
are described in the Tomcat Bible (the examples don't work with
Tomcat 5).

Should I expect Tomcat to find my UserData.class file if I put it
in webapps/myapp/WEB-INF/classes? Do I need to create a web.xml 
or should it find the class file without any web.xml customization?
If anyone has a very simple example that I could drop in to see if
it works, I'd appreciate it. I've already verified that the jsp-examples
all work, but there is a lot of stuff in the web.xml that I shouldn't
need for what I want to do, and finding what I need is probably where
my problems lie.

 Subject: Classpath problems with tomcat on Linux 9
 
 
 
 I'm just getting started with my JSP and tomcat experience, and while
 learning how JSP works, I'm can't get tomcat to recognize supporting
 class definitions that I have placed in myapp/WEB-INF/classes.
 
 Here's my setup:
 * tomcat 5.0.19, running on RedHat Linux 9.0 Pro
 * no customization to $CATALINA_HOME/conf/web.xml
   no customization to $CATALINA_HOME/conf/server.xml
   added my user account as a manager in
 $CATALINA_HOME/conf/tomcat-users.xml
 * I'm running tomcat using the $CATALINA_HOME/bin/startup.sh
 * I'm running tomcat as my normal login id, although I've also
 tried it as
   root just to make sure it wasn't a file permissions issue.
 * I'm able to use the Tomcat manager at
 http://localhost:8080/manager to
   start/stop/reload/deploy applications
 * The jsp-examples appear to work fine
 
 Here's what I'm trying to do:
 * Created the following index.jsp and placed it in
   $CATALINA_HOME/webapps/test
 
 htmlbody
 form method=post action =savename.jsp
 What's your name?  input type=text name=username size=20
 What's your email? input type=text name=email size=20
 Pinput type=submit
 /form/body/html
 
 * Created the following as $CATALINA_HOME/webapps/test/savename.jsp
 jsp:useBean id=user class=UserData scope=session/
 jsp:setProperty name=user property=*/
 htmlbody
 Name: %= user.getUsername() %BR
 Email: %= user.getEmail() %BR
 /body/html
 
 * Created a UserData.java file that defines a public class UserData
   with username and email fields as type String. Added public
   access methods for setUsername, getUsername, setEmail, getEmail.
   I compiled UserData.java using javac, and to produce UserData.class
   which I placed in $CATALINA_HOME/webapps/test/WEB-INF/classes. The
   UserData.java class does not define a package nor does it import
   anything (line 1 is public class UserData)
 
 * deployed the test application using the tomcat manager and it shows
   that the application is deployed with no errors.
 
 * Using IE 6.0, I enter the url to test.jsp and it displays the form as
   expected. I enter a name and email value into the form and press the
   submit button and I get the following:
  HTTP Status 500 -
  exception
  org.apache.jasper.JasperException: Unable to compile class for JSP
  An error occurred at line: 1 in jsp file: /savename.jsp
 
  Generated sevlet error:

 .../work/Catalina/localhost/test/org/apache/jsp/savename_jsp.java:42
  symbol : class UserData
 location: class org.apache.jsp.savename_jsp
 UserDAta user = null
 
 
 I suspect this is a classpath issue but everything I read says
 that if you
 put your classes in appdir/WEB-INF/classes, it will just work.
 
 There must be some basic thing I'm missing. Any help would be very much
 apprciated.
 
 Thanks in advance.

 In my application the generated sessions are identified by a 
 cookie on the client. I only allow single sign on. Now I want 
 to destroy the session and I call in a session an 
 invalidate() and the session isn't available. Then the 
 application  redirect the request to the start page. But 
 there is still the cookie with JSESSIONID on the client and 
 there is no new session possible.
 
 Is there a solution to remove these cookies?

only if one wants to share session data between the differnet tomcat

and does not have anything to do with load balancing.

 most

 Yes.  I did a full stop and start of apache.  There are no errors in the
log
 files either.  Do you, or anyone else, have a workers2.properties file of
a
 working system that you are willing to share?  I've gone through all the
 sections and properties in the latest jakarta jk2 document as well as
other
 How-Tos and don't see what I've missed (I'm afraid I don't understand all
of
 it
 either :).  Does the shm section play a part?  I interpretted it to be
 needed
 only if one wants to share session data between the differnet tomcat
 servers,
 and does not have anything to do with load balancing.
 
 Thanks,

   Hi,
   
   I have set up four tomcat 5.0 servers for load balancing using an
 apache2
   server and mod_jk2 on RedHat 9.0.  The trouble that I am having is
that
  most
   of
   the user sessions are routed to only one of the tomcat servers even
 though
   the
   lb_factor for all is the same, 10.  All tomcat servers seem to be
 working
   since
   I can disable all but one in the workers2.properties file to force
that
   tomcat
   server to be used.  Chnaging the lb_factor can also cause a different
  tomcat
   server to be used most of the time, but I haven't figured out how to
  control
   the balancing by lb_factor.
   
   Below is the workers2.properties file that I am using.

Access Manager and Admin utilities with load balancing enabled

[Yang Xiao]

Hi list,

I have to ask this one more time since no one replied to my last post.

 I have load balancing enabled with TC 5.0.19 and JK2 and I changed the line
in server.xml that says

Engine name=Catalina defaultHost=localhost debug=0

to:

Engine name=Standalone defaultHost=localhost debug=0
jvmRoute=tomcat1

but I can no longer access the admin and manager utilities, please help.

When we used tomcat 3.2.3, I configured it to autogenerate the 
mod_jk.conf to be read by apache/mod_jk. In tomcat 5 I still can use 
it??? I like it becouse each time a app is deployed I just have to make 
apache re-read it's conf file to get the new map to work.

how do I configure tomcat 5 to auto-generate it???

RE: Load balancing with apache2, mod_jk2 tomcat 5.0

[Yang Xiao]

Hi,
Hmm. I commented out the shm.file line in my jk2.properties because it
doesn't seem to be working, but I just did a test with it uncommented, LD
still works fine. 
However, if I use anything other than file=anon in the workers2.properties
file, I don't get the Scoreboard info on the jkstatus page, kind of strange.

Does the shm play a role in this?  I note that you have the following:
[shm]
info=Scoreboard. Requried for reconfiguration and status with multiprocess
servers.
file=anon
#size=104856
#debug=1

Do your tomcat servers have a corresponding entry in their jk2.properties
file?
 Like this?

channelSocket.port=8019
shm.file=/mnt/logs/jk2.shm

Is this even necessary for load balancing?

 But when I start the Tomcat server, I'm getting this error
 
 INFO: APR not loaded, disabling jni components: java.io.IOException:
 java.lang.UnsatisfiedLinkError: /usr/local/apache/modules/libjkjni.so:
 /usr/local/apache/modules/libjkjni.so: undefined symbol: apr_md5_final

It is a constant problem with JK2 JNI lib. I've had it on 2.0.2 and on
2.0.4. 
libjkjni.so needs to be linked against all three APR libs: -lapr -laprutil
-lexpat.

This is the case on Linux (Mandrake 9.1) and on Tru64 UNIX (4.0D). After 
modifying the Makefile, it went OK. It loads and works.

Nix.

Hi,
Thanks for the help
I went back and modified the Makefile with all 3 libraries as you have said,
recompiled and now I'm getting a different error:
INFO: APR not loaded, disabling jni components: java.io.IOException:
java.lang.UnsatisfiedLinkError: /usr/local/apache/modules/libjkjni.so:
/usr/local/apache/lib/libaprutil-0.so.0: undefined symbol: gdbm_errno

I'm not too good with C library programming, so can you help to explain what
this is?

Thanks,
Yang

Hem, unfortunately, I tried that, which worked, but then tomcat complains
about another XML library not being linked. I'm building Apache from scratch
now... please help.

Ugh, looks like there is another link dependency. libaprutil wants a 
link to GDBM library. Try to locate something looking like 
/usr/lib/lib*dbm* and add that to Makefile, without leading lib, 
like this -ldbm.

Nix.

Question on Follow Sym Link

[John Z Yang]

Dear all:
I have seen this question floating around, but just can't dig the answer out.

Does anyone know how to let Tomcat follow symbolic links? Just like the FollowSymLink 
option  in Apache configuration. I need to redirect the ROOT directory.

I remember the older version of Tomcat does this, but I just upgraded to 1.4.2, and it 
seems not working.

Many thanks.

Error Report

[John Z Yang]

Hi,
Is there a way to send a customized error report when our servlet or Tomcat run into 
something wrong? Instead of sending all the detailed stack dump, a more friendly 
message to our customers might be better. I would appreciate it very much if someone 
can give me some pointers on how to customized the error report page.

Many thanks.

Does Tomcat support Unicode URL

We still have not figure out a way to resolve doublebyte URL's with Tomcat. I.E. if we

Tomcat 4.1.8 and httpd-2.0.40-11

[Xue-Feng Yang]

Hi all,

I tried to connect  Tomcat 4.1.8 and Apache2(httpd-2.0.40-11 ) with jk2 
on my redhat 8.0 box, where apach2 was installed when I installed Redhat 
8.0. I use JDK 1.4.1.

When I used ant to build native, I met some errors. I fixed one error:

 [so] /usr/java/j2sdk1.4.1_01/include/jni.h:27:20: jni_md.h: No such 
file or directory

by copying   /usr/java/j2sdk1.4.1_01/include/linux/jni_md.h to 
/usr/java/j2sdk1.4.1_01/include/

Then I met more(see attched). I cannot resolve this. Could anyone help 
me on this?

Thank you very much,

Re: Tomcat 4.1.18 and httpd-2.0.40-11

[Xue-Feng Yang]

Hi all,

I tried to connect  Tomcat 4.1.18 and Apache2(httpd-2.0.40-11 ) with jk2 
on my redhat 8.0 box, where apach2 was installed when I installed Redhat 
8.0. I use JDK 1.4.1.

When I used ant to build native, I met some errors. I fixed one error:

[so] /usr/java/j2sdk1.4.1_01/include/jni.h:27:20: jni_md.h: No such 
file or directory

by copying   /usr/java/j2sdk1.4.1_01/include/linux/jni_md.h to 
/usr/java/j2sdk1.4.1_01/include/

Then I met more(see attched). I cannot resolve this. Could anyone help 
me on this?

Thank you very much,

Xue-Feng

Help needed with Tomcat support for Double Byte Chars

[John Z Yang]

Hi,
We are using Tomcat3.3.1 and Oracle on Linux.
When we enter DoubleByte Chars (CJK, GB2312) in jsp form input, Tomcat 
turns the characters into 's.

The only way we can get around this problem now is to set the IE browser to 
check the temporary files everytime.

Does anyone knows how to fix this problem?

Many thanks.

John

How to configure tomcat to forbid indexing of a directory

[John Z Yang]

Dear all:
I am puzzled that in Apache
the httpd.conf has a directive Options Indexes to turn directory mapping on and off, 
but for tomcat there seems no way to block the user from viewing the directory 
structure unless you create an index.jsp file.

Can anyone give me a pointer to the Options equivalent in tomcat configuration?

Many thanks.

John

unable to read uploaded document

Hi, 
I'm using tomcat 4 as the standalone server. I can

the files in filesystem. All files are there and can
be read from window explorer.
Did anybody know how to work this issue?

Thanks in advance!

newbie install error

[Chuq Yang]

Hi list,
I'm currently trying to install tomcat 3.2.3 on top of a Mandrake
8.0 install.  I am building all of the packages from source, and I have
followed the README file in the jakarta-tomcat-3.2.3-src directory
closely, but I'm getting the following error when I try to install the
jakarta-servletapi package:


Exception in thread main java.lang.NoClassDefFoundError:

I have uncompressed the jakarta-ant and jakarta-servletapi source
packages into the jakarta-tomcat-3.2.3-src directory, and the bootstrap of
jakarta-ant worked.  That's as far as I've gotten.

TIA.

Does Tomcat work with MS proxy server?

[Sam Yang]

Hi,

I am trying to use Tomcat 3.2.1 on my NT 4 server with IIS 4 and Microsoft 
Proxy Server installed. Now Tomcat is working fine with iis via localhost 
so I can access
http://127.0.0.1/examples/jsp/index.html or 
http://127.0.0.1:8080/examples/jsp/index.html. But I can't make it 
accessible via its two ip addresses: 10.XX.XX.XX or 66.XX.XX.XX. BTW, 10.XX 
is a fake address we used for internal network and 66.XX is got from ISP by 
DHCP. I also tried Sun JSWDK 1.01. Same thing. Any ideas will be highly 
appreciated. Thanks a lot for your attentions.

RE: response.sendRedirect vs. requestDispatcher.forward

[A Yang]

Hi,

Thanks for the help. As it turns out, switching
between requestDispath.forward and response.redirect
will trip you up because of differences in what they
expect as their parameters.

RequestDispatch.forward takes a URL that is a RELATIVE
path but also requires a leading slash.

If you are brilliant (like myself) and you change your
code to use response.encodeRedirectURL but you KEEP
that leading slash, well then. Your response will
treat it like an absolute path and wind up plunking
you into a different servlet context, which Tomcat
will generate a new session for.

Thanks again for your help,
Andy

  Conceptually, requestDispatcher.forward() is
 different from
  response.sendRedirect().
 
  In forward(), you are moving inside the same
 webapp, and as such it
  doesn't even reach the client browser. The session
 is maintained.
 
  In sendRedirect(), you're instead moving across
 webapps, and it's the
  browser that redirects to the specified location.
 In fact, it doesn't
  even need to be another servlet, you may redirect
 to an ASP or a static
  page. New request and response are created.
 
  It seems strange that the session is not
 maintained, though, since both
  requests come from the same browser. Perhaps it's
 a bug?

RE: ***** URGENT: UNSUBSCRIBING FROM THE TOMCAT-USER LIST *****

[Yang,Chun]

The problem with my mailer (MS Outlook) is that I don't see a return-path
line.

One odd thing is that unsubscribe doesn't seem to work EVEN if one has sent
the unsubscribe request via his/her subscribing address. I  know for sure it
has failed on me. I am positive about my subscribing address being correct
as I saved the instructions of subscribing/unsubscribing sent by the mailing
list when I initially signed up. And I have tried to unsubscribe at least
twice and both times I failed.

The only solution I could come up with is having all messages from tomcat
user, tomcat user list etc... filtered into the delete folder... :-)
Apparently my setup didn't undergo enough permutations of  tomcat and
user such that the attached message wasn't filtered out... :-)

Any ideas ?

Obviously a lot of people are having trouble unsubscribing from this

Some people (including me and others) have posted instructions on

the subject line such that even those people that are deleting
everything from the list will stop and notice it (for the people
that
want to stay on the list, sorry about that :-).

First of all, you need to find out what address tomcat-user thinks
you're subscribed from.  To do that, look at the headers of a
message
from the list, and you'll see something like:

Return-Path:
[EMAIL PROTECTED]

The Return-Path header line includes the address tomcat-user thinks
you're subscribed from -- with the @ changed to a = to avoid
having two @'s in the Return-Path.  In this example, that's
joe=domain.com, which translates to [EMAIL PROTECTED]

Once you know that address, you can unsubscribe by sending email to

  [EMAIL PROTECTED]

Voila!

So, if you are having trouble unsubscribing, please give this a try.

Re: Compilation error of tomcat3.2.1 integrating with apache1.3.19

[Wei Yang]

Hi Marc-henri,

Thanks for the information. I added code segments for jk_global.h and jk_pool.h
shown at

http://mikal.org/interests/java/tomcat/archive/view?mesg=13351

 and the compilation finished with no problem and tomcat are doing well with apache.

BTW,  I did not add code segment  for jk_jni_worker.c because of  no such variable
defined
error for handle.

 Hi,

 Yesturday, i've got the same problem...
 The reason ? There is no sys/select.h under HPUX !
 I've post it in this Mailing List, and the answer of john P. Dodge was :

 Another alternative is to add an extra #ifndef in jk_global.h, that way
 the same script will continue to work on other platforms. Change
 jk_global.h to look like...
 
 (jk_global.h somewhere near line 86)
 
 #ifndef NETWARE
 #include netinet/tcp.h
 #include arpa/inet.h
 #include sys/un.h
 #include sys/socketvar.h
  do not include sys/select.h if using HPUX11 
 #ifndef HPUX11
   #include sys/select.h
 #endif
 
 #endif

 That's OK, if you do this, you can generate a mod_jk.so, but it don't works
 with Apache.
 I've seen on the archive of this list that it's a problem with 32 - 64 bits
 compilation.
 Matchim, Brian wrote on Mon, 11 Dec 2000 (let see
 http://mikal.org/interests/java/tomcat/archive/view?mesg=13351 ):

 I far as I can tell, the reason is that HPUX11 is a 64-bit OS, but it uses
 32-bit compilers as default.
 Tomcat's distribution code attempts to use the following dl operations:
 dlopen(), dlload(), dlerror(),
 and dlsym().  Though the code will compile using a 32-bit compiler, it will
 not operate correctly
 and Apache will refuse to start.
 There are two ways around this of course, use a 64-bit compiler (such as
 gcc),
 or you can modify the code to use the 32-bit equivalents, that is,
 shl_load(), shl_open(), etc.

 Well done, but i'm using gcc 2.95.2 on hpux, and it doesn't works...
 So, i decide to go on the gnu gcc site, and i've seen the page
 http://gcc.gnu.org/install/specific.html#hppa*-hp-hpux11 that specify :

 GCC 2.95.2 does not support HP-UX 11, and it cannot generate 64-bit object
 files. Current (as of late 2000)
 snapshots and GCC 3.0 do support HP-UX 11.

 What should we do ?

 I hope i give you some informations to continue, and i hope you'll help me
 to if you find before ;o)) ...

Re: Caching a servlet? Sessions in IE?

[A Yang]

 Have you tried setting the cache and expire headers?
 
 Try addding:
 
 response.setHeader("Cache-Control","no-cache");
 //HTTP 1.1
 response.setHeader("Pragma","no-cache"); //HTTP 1.0
 response.setDateHeader ("Expires", 0); //prevents
 caching at the proxy server

I have the following:
 
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Pragma", "no-cache");
response.setHeader("Expires", "-1");

I even have it in "controller" JSP's which only do
some basic logic and page forwarding. 

It really looks like it's my controller servlet that
is being cached, and I don't understand that at all. 

I shouldn't be setting any headers in the response if
I'm going to forward it somewhere else right?

Caching a servlet? Sessions in IE?

[A Yang]

Hi,

This is a weird one that we can only reproduce in IE.
Netscape works fine. I'm using Tomcat 3.2.1 with
Apache via mod_jk.

I have a "Main Menu" servlet that forwards the user
through a series of JSP/servlet sequences based on a
parameter that identifies which "item" was selected in
the Main Menu.

The problem is that when the user finishes one path,
and is sent back into the Main Menu servlet with
another parameter (i.e., option 2 after completing
option 1), it looks like the Main Menu servlet has
been cached! I have guardian log messages set at the
beginning of the doPost and doGet methods but they
don't get called. Instead, the user simply re-enters
the path they have just completed.

Even if I remove all attributes and invalidate the
session before going back to the Main Menu servlet, it
still continues down the already-travelled path.

Has anyone seen this behaviour before? Sessions seem
to hang around regardless of whether it's been
invalidated or not.

Any help would be greatly appreciated.

Thanks,

Configuring mod_jk

[A Yang]

Hello Everyone,

I was just wondering if anyone could help make sure
I've got mod_jk configured properly.

Assuming my host name is www.myhost.com and I have a
servlet context called /tomcat.

In my httpd.conf, I have my DocumentRoot set to the
/tomcat document root (for the sake of testing). I
also have:

DirectoryIndex index.html index.jsp

In my mod_jk.conf, I have the following excerpt:

JkMount .*.jsp ajp13
JkMount /servlet/* ajp13

JkMount /tomcat/*.jsp ajp13
JkMount /tomcat/servlet/* ajp13

So, what this means is that the following work:

www.myhost.com/tomcat/index.jsp
  and 
www.myhost.com/tomcat/myservlet

I'm pretty sure that if I just specify
www.myhost.co/tomcat - then index.jsp gets picked up
automatically. Which is good.

Similarly, www.myhost.com/tomcat/something.htm works.

However, when I try something like:

www.myhost.com
  or
www.myhost.com/something.htm

I get the dreaded infinite-CPU-looping java process
because it's trying to resolve a context and is unable
to.

So, my hypothesis is that Apache is NOT serving up the
html documents, because otherwise, Tomcat via mod_jk
should never have to resolve html files.

Any insight would be appreciated.

Checking for timed-out sessions

[A Yang]

Hi,

Can anyone tell me what the proper convention for
checking for invalidated sessions is? Do people really
write code checking for whether the session is valid
EVERY time they are about to refer to one? And if so,
do they just examine the LastAccessedTime and create a
new session accordingly?

If this is the case, then you'd think that part of the
base class functionality would be a method that
automatically compares it to the MaxInactiveInterval -
instead of making me subclass HttpSession myself8)

Also, is the behaviour of a timed-out session defined
if I try to access one? Does Tomcat automatically
invalidate the session after it exceeds the
session-timeout value?

Thanks,

Question about sessions

[A Yang]

If I instantiate a javabean from a JSP: 

jsp:useBean id="myBean" class="com.mycorp.somebean"
scope="session"
jsp:setProperty name="myBean" property="*"/
/jsp:useBean

and hand off control to a servlet where I retrieve the
session using:

HttpSession session = req.getSession(false);

Shouldn't session.isNew() return "false" because the
session already exists?

Running Tomcat as non-root

[A Yang]

Hello All,

Can anyone tell me how to set up directory permissions
to permit running Tomcat as a non-root user? 

According to previous posts in the mailing list, I
should be using 'su - nobody' when kicking off Tomcat,
but nobody doesn't have authorities to write to
usr/local.

What is the best practise for setting up Tomcat?
/usr/local/tomcat should be owned by Root shouldn't
it? I'm running Red Hat 6.2.

Thanks,

Re: Running Tomcat as non-root

[A Yang]

 /usr/local/tomcat doesn't necessarily have to be
 owned by root. The only thing you need to so is make

 sure that whichever user you run tomcat as has write

 permissions to the logs, conf and work directories
 (those are the only ones Tomcat writes to I think).

I was a little iffy about leaving the entire conf
directory writable by the nobody group, so I wound up
just checking the java exceptions and permitting group
write access to the affected files - mostly they are
the automatically generated files like *.conf-auto.

On a side note, I found that I was regenerating the
Windows registry settings for redirecting IIS every
time I started up Tomcat.

 This doesn't have to be 'nobody' though. You could 
 create a tomcat or www user for example.

Yes, I just figured I would use the same nobody user
that apache was using.

Would it be best practises to have apache and tomcat
running on separate, minimal userids?

 And if you want it to be owned by root, that's fine,
 just use the group permissions to set the write 
 access.

Do you mean something like:

 1 -r--rw-r-- 1 root nobody1024  foo

Thanks,

ClassCastException

[Yang,Chun]

Hello all, I am encountering a ClassCastException when compiling a JSP page
in the following scenario:

1)  a servlet MyInitServlet creates an object MyObject and saves it to
the context by

getServletContext().setAttribute("myobj", MyObject);

2)  a JSP page tries to access MyObject by doing:

MyObject mo = (MyObject) application.getAttribute("myobj");

The above statement caused Jasper to throw a
ClassCastException. 

3)  I then tried by introspecting the generic object returned by
application.getAttribute()

mo2 = application.getAttribute("myobj");

And I was able to print out the class name and all the public
methods in the class associated with mo2. And everything looked right. But
the statement

mo2 instanceof MyOjbect

still evaluated to false (hence the ClassCastException)..

What did I do wrong ? 

Your help is greatly appreciated!

Nope, MyObject is not defined as an inner class and is already in a .java

Are you using an inner class for declaring MyObject ?

I faced a similar problem when I daclared a class as below in a jsp
page,
create an object of type ax,
saved it in a session, and retrived it in another jsp page which had
the
same %! class ax ...%
code fragment.

%!
class ax
{
public int x;
}
%

The problem is that you cannot cast inner classes as they are
qualified by
their enclosing class (AFAIK)
Try moving class MyObject to a seprate .java file.

starting Tomcat with nobody in RH Linux

[A Yang]

Hello all,

There has been a fair bit written about starting up
Tomcat under a non-root account, but I'm too much of a
Linux admin newbie that I'm having trouble putting it
all into context.

I have Apache running under nobody, but I'm having
trouble getting Tomcat to. I try to startup Tomcat
using "su - nobody" but run into permissions problems
because my /usr/local/tomcat directory is owned by
root.

I look at Apache, and the owner and groups are numeric
but the values don't match any of my group id's.

I mean, I shouldn't try to add nobody to my root group
right? Red Hat doesn't even define nobody to be a real
user.

What am I missing about file ownership and special
accounts like nobody?

Thanks,

Large Scale Tomcat use

[A Yang]

Hi,

I was just curious - if I wanted to architect a
multi-tier web app environment, what would be the best
approach in terms of scalability, performance and
security:

1. Apache -- Firewall -- Standalone Tomcat -- Firewall
-- DB
2. Apache -- Firewall -- Apache/Tomcat -- Firewall --
DB
3. Apache/Tomcat -- Firewall -- Standalone Tomcat --
Firewall -- DB
4. Apache/Tomcat -- Firewall -- Apache/Tomcat --
Firewall -- DB
5. Apache/Tomcat -- Firewall -- DB
6. Apache/Tomcat -- Firewall -- Apache/Tomcat --
Firewall -- DB

"Apache/Tomcat" refers to Apache w/ mod_jk.so and
Tomcat running on the same machine.

I'm not familiar with the recommended approaches
towards distributing Apache and Tomcat, so some of
these options might not make sense (ok, none of them
might make sense...)

Just thought I'd see if anyone has "best practices" or
experience with doing so - this seemed related to load
balancing, but I thought I'd try a new thread.

Regards,
Andy
