Hello Everybody, 

Well 'X' database is the place where we have got the already known sequences
and then we try to match the sequence generated by us with these standard
squences. Finally we generate the HISTOGRAM corresponding to the nearly
matched sequence. No we are not using the JDBC at all.

This exception is nothing to do with the Tomcat. Yes our servlet asks for
the 'username' and 'password' and only lets you log into the application  if
your name is hard wired into our servlet code and for that you should be
registered user of our database. This authenication is for security reasons

Finally thanks for letting me know about the active session stuff.

Well, it sounds like you have several problems but it is hard to 
with the information supplied. 

What is an 'X' database?  Are you using a JDBC driver to connect to it? 

The IOException about the LOG/BAN files is not a Tomcat message.  Is 
servlet trying to do some sort of logging? 

The message /proj_GR:running:0 in the manager app tells you that the 
is loaded.  The 0 means there are no active sessions.

Hi Everybody, 

We are trying to connect with our 'X' database with the help of 
servlets. We 
are using the socket connection to the server and try to match the 
we paste in our User Interface and correspondingly generate the graph of 
matched sequence. But somehow we not able to connect with the database. 
flashes the following error message: 

Error in JCS:: Connection refused: connect 

Besides we have an IOEXCEPTION generated: cannot close the LOG/BAN files 
" " stream closed. 

Where JCS is the server we have generated ourselves to connect to the 
database.I am pretty certain that the EXCEPTION in the servlet code is 
causing the ERROR. We are not able to DEBUG this EXCEPTION. Can anyone 

Since we are serving our application using TOMCAT I would like to know 
we need to do to start a new instance of our application. When we LIST 
RELOADING(using the MANAGER tool) we get: /proj_GR:running:0 is the 
on the right side to do anything with the instance. 

To resolve we have tried importing packages like* and*. 
Can someone DEBUG this EXCEPTION. 

Thanks in advance
