Hi list,

I have spent last 15 working hours trying to figure out the cause of a
strange bug. Home page on one of our web sites sometimes gets
generated with no content - as a blank page, the response buffer
having size 0. We use caching filter (modified CachingFilter from
Ehcache 1.3.0) which uses a response wrapper to capture responses to
make caching possible. The response wrapper internaly uses standard
classes ByteArrayOutputStream and PrintWriter from the Java API.

The page cache time-to-live is set to 1 day. When the page is
generated first time by jsps and tiles it is put into cache, and
served for next 24 hours from the cache. After 24 hours  it gets
generated again.

The manifestation of the bug is that randomly, the homepage gets
generated as a blank page, about once in every 3 cache refreshes. When
it occurs, the ByteArrayOutputStream has size 0, after the generation
of the page has completed.

Generating the homepage involves pulling some data from the database,
which changes rarely, about once every week. I put cache time to live
300 seconds to eliminate the posibility that corrupt data from
database causes errors in page generation. With 300 second time to
live the problem was still there. The data in database does not change
between good and faulty page generations. Home page is relatively
simple - it does not involve pulling data from other data sources. It
just reads some data the database and uses that data to make some
html, using jsp.

After turning on logging on database calls, all filters, and using a
PrintWriter decorator inside our response wraper that echoes all print
statements to the log,  I found out something strange -

A correct page generation logs some database calls (by the database
logger), then a chunk of html (by the logging PrintWriter decorator,
as a result of flushing JspWriter after enough out.write calls have
been made), then some more database calls, then some more html.. and
the page gets generated.

** A faulty generation (the one that produces a blank page) logs
exactly same database calls as a correct page generation, but the log
entries produced by the echoing PrintWriter are missing! **, like as
jsps are executing normally, but something is wrong with the JspWriter
out object.

I am suspecting that somehow JspWriter writes somewhere else, not
where it should. It should write into response wrapper's buffer,
though the echoing/logging PrintWriter. But there is no PrintWriter
echo and no bytes in response wrapper buffer... more exactly,
*sometimes* there is no PrintWriter echo and no bytes in response
wrapper buffer.

I have read all the code that makes up the life cycle of PageContext
and JspWriter on the docjar site (not sure for what version of
Tomcat), and couldn't find anything that would help me solve this.

http://www.docjar.com/html/api/org/apache/jasper/runtime/JspWriterImpl.java.html
http://www.docjar.com/html/api/org/apache/jasper/runtime/PageContextImpl.java.html
http://www.docjar.com/html/api/org/apache/jasper/runtime/JspFactoryImpl.java.html

After adding some more logging statements I found out that 1 instance
of JspWritter and 1 instance of PageContext are used shared across all
page generations (site has low traffic and rarely 2 requests in same
time). Same JspWritter and  PageContext instances sometimes
participate in good page and faulty page generations.

I was hoping that someone on this list might know something that could
help me find out why is this happening. Please help.

Re: Did anyone had problems with JspWriter in Tomcat 5.5.17?


I forgot to write information about our environment:

Os: Red Hat 4.1 (Linux 2.6.9-42.EL) on i386
Jvm: Sun's Java HotSpot(TM) Client VM version 1.5.0_07-b03
Tomcat 5.5.17
We also use Spring, Informix db, iBatis, Jsp (tiles) and Ehcache 1.3.0
We have made 5 sites for now with these same technologies. The bug
only occurrs on the home page on the least visited site.. Other sites
are visited very often (we have to use load balancing on 4 servers)


And 1 more important thing - when the caching filter is turned off,
pages always get generated fine. But.. the code that creates the
wrapper is same for all apps/pages, and works fine in other apps.

Re: Did anyone had problems with JspWriter in Tomcat 5.5.17?


The caching filter uses a BlockingCache. A miss (get that returns
null) locks that entry/key, and other threads that try to get the page
from the cache using the same key, must wait until the thread that
locked the entry puts something into the cache and releases the lock.
Lock are released implicitly when cache put method is called, by the
thread that locked it. All this is implemented inside Ehcache. We
havent observed any thread deadlock problems (using JMX to monitor
servers)

Lock implementation is net.sf.ehcache.constructs.concurrent.Mutex
which is a copy of Doug Lea's mutex class from standard Java API,
copied and imported into Ehcache.

Re: Did anyone had problems with JspWriter in Tomcat 5.5.17?


The problem seem to happen before writing to the cache. Jsps write to
response wrapper's buffer.. well, when they do page gets generated
fine, when they don't we get a blank home page served and put in the
cache.

Re: Tomcat cannot access the resources in an HTTPS webapp

2007-07-16 Thread Lyallex


Hi

There seems to be an awful lot of confusion on this list about
container managed security and https ... I know I was confused when I
started with it.

As I see it the two are not really connected.

I think what you want to do is to force an https request for certain
resources in your application.

One way of doing this is to add this to your security constraint

user-data-constraint
transport-guaranteeCONFIDENTIAL/transport-guarantee
/user-data-constraint

Of course, as always, this is not the complete answer but it should
get you started.

(see http://java.sun.com/j2ee/dtds/web-app_2_2.dtd for where this goes
in web.xml)

If you were to configure the
auth-methodFORM/auth-method (for example)
with a suitable login form then when you attempt to access a protected
resource that has the required transport guarantee associated with it,
access to that resource will not only require a user to log in but
access to the resource itself will 'automatically' be over https.

As usual I'm sure there are other (better) ways of doing this but it
works for me.

I hope this helps.

Re: change in local directory deployment behavior between 5.5 and 6

Subject: change in local directory deployment behavior between 5.5 and 6

Hi,

 I have been searching for a solution to this problem for a while, but 
it's difficult to search on when the keywords match so many general 
topics.

 In tomcat 5.5, I was able to use manager to deploy from a directory on 
the filesystem, and tomcat would use that directory for the source. It 
would not copy the contents of the directory to its webapps directory. I 
could stop tomcat, start it again and pick up changes in the class files 
of the app. This was very quick because no file copying was going on.

 In tomcat 6, it now copies all of the files to the webapps directory. I 
can no longer just stop and restart tomcat to pick up the changes in the 
class files because tomcat has its own copy. I have to undeploy and 
redeploy at minimum, and it takes quite some time and extra work on my 
part.

 Is there a way to configure tomcat 6 get the old tomcat 5.5 behavior 
back? Thanks for any help.

 Alice

Hi Alice how were you actually deploying it? Using an IDE, ant, HTTP?
It doesnt actually look like its changed much from 5.5 to 6... so it may 
just be the tool thats doing it different with TC6?

Anyway let me show you how I do it once you have this ant script setup, 
its so handy, you cant live without it.

It just so happens its actually setup now for what you need
If my notes are not clear... the trick is just to setup the context.xml with 
its own docBase location... in the unpacked web app in one of your 
folders.
Then when you run this ant script... TC will use that unpacked webapp... 
just point config at the context in the webapp.

Have fun

project name=Deployer default=deploy basedir=.

 path id=deployer.classpath
   fileset dir=${basedir}/lib
 include name=*.jar/
   /fileset
 /path

 taskdef resource=org/apache/catalina/ant/catalina.tasks
  classpathref=deployer.classpath/

 !-- point url at manager
change username and password to Tomcat Admin
war - is the path to the thing you trying to install
dont change update - it makes it undeploy existing first
path - is the Context (the uri you want it to be)
config - points via a context file that will be used as the docbase
 if you use config you dont use war or localWar
 ie it will point tc at the existing installation that you have at that 
docBase

 - ie context.xml looks like this -
   ?xml version=1.0 encoding=UTF-8?
   Context docBase=D:\GARBAGE\TestSite path=/Ignored/

localWar - will move the contents of your unpacked web app to tc

In Netbeans right click and run task 'deploy'

If you dont like ant then this will also work

Use a combination of url-pattern and transport-guarantee (along with

 generated with no content - as a blank page, the response buffer
 having size 0. We use caching filter (modified CachingFilter from
 Ehcache 1.3.0) which uses a response wrapper to capture responses to
 make caching possible. The response wrapper internaly uses standard
 classes ByteArrayOutputStream and PrintWriter from the Java API.

 The page cache time-to-live is set to 1 day. When the page is
 generated first time by jsps and tiles it is put into cache, and
 served for next 24 hours from the cache. After 24 hours  it gets
 generated again.

 The manifestation of the bug is that randomly, the homepage gets
 generated as a blank page, about once in every 3 cache refreshes. When
 it occurs, the ByteArrayOutputStream has size 0, after the generation
 of the page has completed.

 Generating the homepage involves pulling some data from the database,
 which changes rarely, about once every week. I put cache time to live
 300 seconds to eliminate the posibility that corrupt data from
 database causes errors in page generation. With 300 second time to
 live the problem was still there. The data in database does not change
 between good and faulty page generations. Home page is relatively
 simple - it does not involve pulling data from other data sources. It
 just reads some data the database and uses that data to make some
 html, using jsp.

 After turning on logging on database calls, all filters, and using a
 PrintWriter decorator inside our response wraper that echoes all print
 statements to the log,  I found out something strange -

 A correct page generation logs some database calls (by the database
 logger), then a chunk of html (by the logging PrintWriter decorator,
 as a result of flushing JspWriter after enough out.write calls have
 been made), then some more database calls, then some more html.. and
 the page gets generated.

 ** A faulty generation (the one that produces a blank page) logs
 exactly same database calls as a correct page generation, but the log
 entries produced by the echoing PrintWriter are missing! **, like as
 jsps are executing normally, but something is wrong with the JspWriter
 out object.

 I am suspecting that somehow JspWriter writes somewhere else, not
 where it should. It should write into response wrapper's buffer,
 though the echoing/logging PrintWriter. But there is no PrintWriter
 echo and no bytes in response wrapper buffer... more exactly,
 *sometimes* there is no PrintWriter echo and no bytes in response
 wrapper buffer.

 I have read all the code that makes up the life cycle of PageContext
 and JspWriter on the docjar site (not sure for what version of
 Tomcat), and couldn't find anything that would help me solve this.

 
http://www.docjar.com/html/api/org/apache/jasper/runtime/JspWriterImpl.java.html 



 
http://www.docjar.com/html/api/org/apache/jasper/runtime/PageContextImpl.java.html 



 
http://www.docjar.com/html/api/org/apache/jasper/runtime/JspFactoryImpl.java.html 




 After adding some more logging statements I found out that 1 instance
 of JspWritter and 1 instance of PageContext are used shared across all
 page generations (site has low traffic and rarely 2 requests in same
 time). Same JspWritter and  PageContext instances sometimes
 participate in good page and faulty page generations.

 I was hoping that someone on this list might know something that could
 help me find out why is this happening. Please help.

 Hi Joe !!! :

 Many thanks by your answer, I'm really a newbie in the Axis world

POJO is a plain Java objects that you cannot throw things!

I tend to return results wrapped in XML strings containing
types (=ok, error, ...) and contents. For clients, any exceptions
happened in transport will be captured by try {} catch blocks.
Errors occured in POJO servers will be embedded in return strings
as XML strings. Note that use of SOAP means that you should
live with XML!

Http Header Cache-Control

2007-07-16 Thread gerocoma-forophp

Hello, 

I've apache 1.3.36 + tomcat 4 + mod_jk 3.3

I'm very new to web servers. I have a problem with the
cache configuration of a tomcat web application. Using
a http headers inspector, I can see that no cache
control is been sent. 

I'd like to send CacheControl: no-cache in the
header of every page of my app. First of all, is this
something that I should configure in apache, in tomcat
or in mod_jk???

Then, How can I do it?

Thanks ;)

Capturing Tomcat thread dumps from startup.bat (Windows)

2007-07-16 Thread Jayson Enriquez

I am unable to copy Tomcat thread dumops when launching it from
Startup.bat from a command window. At the end of the day I do a select
all and copy but it only captures part of the thread dump. Is/Are their
other ways to capture thread dumps from a command (DOS) window? Buffers
are set to 999

 

I do need a full day of activity.

 

I've also tried 

 

Option 1:

 

Start command window and 'cd' to 'C:\...Tomcat\bin' folder where
'startup.bat' file resides and enter startup.bat  tomcat.log

 

This creates tomcat.log file in the same folder as startup.bat. I have
attached the file which got generated now. The log gets updated with
first 4 lines and that's all. 

 

Option 2:

 

In the start-run type C:\Apache\Tomcat\bin\startup.bat  tomcat.log
and the log is generated with same output. The log gets updated with
first 4 lines and that's all.

 

 

 

Thank you

Re: Tomcat cannot access the resources in an HTTPS webapp

2007-07-16 Thread Dimitris Mouchritsas

Thank you for your responses. Well, I was a bit lost in the specs but
after looking up transport-guarantee I got what I
wanted. Out of curiosity though what should I do to add tomcat user
authentication?
I tried adding:
security-constraint
web-resource-collection
web-resource-namesearch/web-resource-name
url-pattern/ch13/search/*/url-pattern
/web-resource-collection

user-data-constraint
transport-guaranteeCONFIDENTIAL/transport-guarantee
/user-data-constraint
!-- add here --
 auth-constraint
  role-nameadmin/role-name
/auth-constraint
!-- end add --
/security-constraint
but tomcat, while asking me to log in, and I did, denied access to the
resource. Without the addition I get the https encryption
that I require.

 Read section 12 of the servlet spec:
 http://jcp.org/aboutJava/communityprocess/mrel/jsr154/index.html

 Use a combination of url-pattern and transport-guarantee (along with
 their surrounding elements, of course).

 Note that the Tomcat doc does not duplicate any information in the
 servlet spec; you have to read both.

Container-managed authentication is unique to the container, so refer to
the appropriate Tomcat doc:
http://tomcat.apache.org/tomcat-6.0-doc/realm-howto.html

If you're using the default Realm (likely), you need to add
appropriate userid, password, and role names to conf/tomcat-users.xml,
and restart Tomcat.

Something is not right. It's possible that the (200) is a programming

is unlikely.

What is more likely is that you are misreading your own configuration

Re: Thread waiting

André,

André Vila Cova wrote:
 How can I say for what is the tread waiting?

As a follow-up to David's reply, I'd like to be a little more specific.

 http-8085-Processor23 daemon prio=1 tid=0xdd4b7ae8 nid=0x2d41 in
 Object.wait() [0xde29b000..0xde29c020]

This line of output tells you which thread (http-8085-Processor23), what
type of thread it is (daemon), it's priority, and then method it's
currently in (Object.wait).

at java.lang.Object.wait(Native Method)

This line confirms that the thread is in Object.wait().

The JVM knows that Object.wait is a special method that requires a
monitor (the object being waited for), and it tells you

- waiting on 0xe61981f0 (a
 org.apache.tomcat.util.threads.ThreadPool$ControlRunnable)

This line tells you what the monitor is (the object being waited on).
It's the object with reference 0xe61981f0, which is a
org.apache.tomcat.util.threads.ThreadPool$ControlRunnable object. I'm
not expert on Tomcat internals, but I'm guessing that ControlRunnable is
related to request dispatching.

This thread is clearly waiting on a notification of a request coming
into the server. Therefore, it can be considered IDLE, and not doing
anything at all.

If you really do have multiple Connectors, and you are only using one
(which is likely), then the threads for the other 2 connectors will
always be idle.

Re: Http Header Cache-Control

To whom it may concern,

[EMAIL PROTECTED] wrote:
 I've apache 1.3.36 + tomcat 4 + mod_jk 3.3

Something is wrong with that mod_jk version, by the way. The most recent
release of mod_jk is 1.2.23.

 I'm very new to web servers. I have a problem with the
 cache configuration of a tomcat web application. Using
 a http headers inspector, I can see that no cache
 control is been sent. 

Cache-control headers are usually not sent unless they are necessary.
Are you sure they are necessary for your environment?

 I'd like to send CacheControl: no-cache in the
 header of every page of my app. First of all, is this
 something that I should configure in apache, in tomcat
 or in mod_jk???

I'm sure there are other ways to do this, but in Tomcat, you can do it
easily by writing a simple Filter and installing it in your
application. Writing a filter is as simple as writing a class that
implements javax.servlet.Filter (3 methods) and then installing it by
adding this to your WEB-INF/web.xml file:

filter
filter-nameencodingFilter/filter-name
description
A filter to ensure that the request has a valid
character encoding. This fixes problems when the request is
being sent in (say) UTF-8 but the user agent doesn't specify
the encoding.
/description
filter-classorg.childhealthcare.diagnosis.servlet.EncodingFilter/filter-class
/filter

This stuff goes right at the top of the web.xml file, just inside the
web-app element. Note that filters are applied in the order they
appear in web.xml, so you might want to familiarize yourself with any
existing filters before you install this one.

The method you'll want to look for when implementing your filter is
HttpServletResponse.addHeader(). You will probably want to add your
header /before/ you hand-off processing to the next filter in the chain.
Please please /please/ read the documentation for Filter.doFilter before
you get started. You can find this documentation here
(http://tomcat.apache.org/tomcat-5.5-doc/servletapi/javax/servlet/Filter.html)
as well as other places, I'm sure.

Hope that helps,

Subject: How to deploy a web app on tomcat.. help needed plz.. :)

Hi,

I'm trying to deploy a web application on tomcat 5.5.23 but I'm not
exactly sure how to do so (beginner).

I've copied the war file and archive into the webapp directory but i'm
getting a message saying the requested resource is not available.

I previously had another web app deployed but with the help of my cousin
so i'm not entirely sure what he did, this was still running fine with
tomcat until I put my new war file into webapp, now I am getting the
same message ass above for this application too.

Does tomcat only allow one web application war file into the webapp
directory at a time maybe???

Thanks in advance for replies,

Pinky

Re: birtruntime 2.2.0 crash on tomcat 5.5.20

Since it's crashing in a printer driver DLL, I suggest removing the
problem printer and specifying a different printer as the default in
Windows.

You might want to take a look at the doc:
http://tomcat.apache.org/tomcat-5.5-doc/appdev/index.html
especially this part:
http://tomcat.apache.org/tomcat-5.5-doc/appdev/deployment.html

 I've copied the war file and archive into the webapp directory but i'm
 getting a message saying the requested resource is not available.

Don't bother giving us an approximation or your interpretation of the
message - post the exact message, since you have it readily available.
As another poster already noted, take a look in Tomcat's logs for more
information.

 Does tomcat only allow one web application war file into the webapp
 directory at a time maybe???

Of course not.  The standard Tomcat 5.5 distribution comes with six
applications in webapps, plus two more in server/webapps.

Exactly what are you referring to with webapp directory?

What are you typing into the browser to access this app?  Your error 
message says LoginApp wasn't found, but here your servlet is named 
login.  Try using login in your URL instead of LoginApp.

Re: About Using memory JVM and Tomcat

2007-07-16 Thread alvaro tovar


Christopher Schultz say.

Most 32-bit JVMs can't actually give you 3GB of heap space.
You'll probably be limited to somewhere between 1.5 - 2.0GB. If you have
a 64-bit processor and OS, go with a 64-bit JVM and then you can get
/lots/ of memory.
