Hi Prashant
So the exact problem is that after your jsp page is called and the data
processed then the file is incomplete?
Presumably then you are using ordinary file I/O to write to this file?
If that's the case, then I think the answer to your original question is
"No - no internal buffer of tomcat is holding the data"
Tomcat's buffering is connected with processing servlet
request/responses and it doesn't seem that you are using the response
object to write your data to the output stream. I assume that you have
checked that all of the data is being read from the request by some
logging or debugging?
I would suspect that a file or stream is not being flushed/closed and
that when tomcat is stopped this flushing is happening because the
streams are being closed automatically.
Maybe you can create some unit tests which can help isolate this
problem. It may be either in your file writing code or in the way you
are using the jython libraries. Without seeing your code in detail its
difficult to be more helpful. I'd guess that you could take your core
logic and replicate the problem independently of tomcat.
One other point is that saving this file in the tomcat home directory
doesn't seem particularly elegant. You could use the default work
directory. I doubt that has any relevance to the problem

Hi Alan,
Below are the details for the versions and OS:
Tomcat Version : 6.0
OS : Windows XP
JVM : 1.6
The way web is structured is:
I have some precompiled python scripts which are actually compiled by jython
into java classes(Before deploying).
I have one python script which uses these precompiled python classes.Now I
am giving one file as
input to this python script and it internally produces the output file using
this input file.
This output file is saved locally in the parent directory of Tomcat.
There is one jsp page which takes input from the user and then passes the
request to Java class which actually
calls this Python script.
Note:The python script is actually called using the PythonInterpreter class
and all those Java and Jython integration techniques.
Sincerely,
Prashant golash

Hi Prashant
The first question - which version of Tomcat? What operating sytem? What
JVM? and in your case which version of Jython?
Secondly please could you clarify exactly how your web is structured?
My understanding from your first email is:
1. servlet is called with request containing a file (presumably mutlipart
encoded?)
2. the file data is then fed into a python script running either using a
java6 ScriptManager or similar.
3. and then what? Are you streaming the output from that file straigth into
the PrintWriter/OutputStream of the HttpServeltResponse?
Or are you trying to save the file locally?

Hi Tomcat-Apache Gurus,
I have a web application where from the front end user loads a file
and gives it as input to Java classes.The file is given as input to
a python script which converts it into some other format.
Here I have used the concept of jython.
The file is converting properly in the parent
directory of Tomat but with some of the data which is missed.The problem
is
when I close the tomcat,then additional data is added to the converted
file
which
completes the correct conversion.
I want to know whether some internal buffer of Tomcat is holding the extra
data.
If so how to retrieve it.
Sincerely,
Prashant golash
