All of this is out of CentOS repositories and I'm limited to sticking
with what is in the repositories.

If you have any guidance with what I am working with, it would be
greatly appreciated.  I do appreciate the input that you have given
thoughdoes give me a couple ideas on hunting with what I have.

Thanks!

Thanks for the pointers, Mark.  From what you are saying, this would be 
a Tomcat-specific solution.  I was hoping for something that would work 
in standard way so it would be portable.  While we use Tomcat ourselves, 
we've had users who run on other containers.  I'll take a look though 
since maybe it's something that can be plugged into other containers, too.

processing of tlds failed -- application still works -- why?

[Satish Kumar]

Hi All,

I am seeing the error below while deploying a web application on Tomcat
6.0.16. Note that the parser used for processing tlds is Crimson -- I expect
Tomcat to use the default Xerces parser to process tlds, but it using
Crimson parser that is in a jar in WEB-INF/lib. It seems this issue is
related to bug 29936 fixed in 6.0.17:
https://issues.apache.org/bugzilla/show_bug.cgi?id=29936 . I don't see this
error on Tomcat 6.0.18.

Question: My application works fine. The custom tags defined in the tld the
parsing failed on still work. Why do the custom tags work when tld parsing
failed? Can this error be ignored? What is the purpose of method
processTlds? (to create tld cache?)

Ref:
http://tomcat.apache.org/tomcat-5.5-doc/config/context.html#Standard_Implementation
What happens if I set processTlds context attribute to false while tlds are
used in the webapp?

I didn't know that 10054 was meant as a winsock error code, although I have
seen the 10054 often enough in other (non-http) applications using Winsock.

Thanks for your kind. I prefer to this manner also. And it is why I ask

Of course,it is a java io question,not related to tomcat. :)

 For example:the log:

 10.33.2.45 - - [08/Dec/2010:08:44:43 +0800] "GET /poi.txt HTTP/1.1"
 200 672 "-" "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US;
 rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8"

 will be saved in the db in this format:

 ip  timemethod
 uri   statusbytes  browser  platform


 

 10.33.2.45 2010-10-08 08:44:43  GET/poi.txt200672
 Firefox/3.6.8winxp

 And now I meet some problems when I read the log file like:
 localhost_access_log.2010-12-20.txt

 I read the file line by line,but sometime I can not get a complete line
 since this file may be written in.

 So,someone suggest me add a db appender(log4j),which will do the
 procesing
 work and then export the log to db.

 ---

 Now,from the link you give me ,it seems that tomcat does use log4j to
 create
 its access log.

The logging page which I pointed you to, does not say that Tomcat uses

It says that you /can/ configure Tomcat to use log4j, instead of the

The AccessLogValve documentation page does not say either that it uses
log4j.
But what it does say at the very beginning, is that the output file is

 Hi.

It is not very clear what you are asking, specially since you do not
specify which version of Tomcat your are using, under which Java version
and
on which platform.

Assuming you are using Tomcat 6.0.x, the on-line documentation for
logging
is here :

http://tomcat.apache.org/tomcat-6.0-doc/logging.html

Maybe read it first, and then come back if you have a specific question ?
(But then try to specify the question clearly)

maven apache wrote:

I wonder how is the tomcat log generated,I mean the log like this;

if tomcat also uses log4j to generate the logs and I have access to
the tomcat's log4j config file.

More details can be found in this post:

This is best reported to the Axis2 mailing list, users there may be able
to advise on whether it's possible to prevent this from happening by
configuring something.

If not, it may be a bug that community needs to address.

Yes. You'll need to extend BaseDirContext in 
org.apache.naming.resources. For some examples, see FileDirContext and

 I wonder how is the tomcat log generated,I mean the log like this;

 localhost_access_log.2010-12-20.txt

 I want to export the logs to db. Some one suggestion I directly add
 one Appender 

 if tomcat also uses log4j to generate the logs and I have access to
 the tomcat's log4j config file.

 More details can be found in this post:

 http://stackoverflow.com/questions/4486620/randomaccessfile-probelm

 So I wonder if this is possible?
