Make sure you include the finally block to close your connection.
Add the following after the catch block
finally {
try { if(connection != null) connection.close(); }
catch(Exception e) {}
}

Subject: Re: DSN less connection for SQLServer/Oracle in java
Hello SriHari,
I have attached a sample jsp file which pulls out a list of all the
databases defined
on your MS SQL server using the freetds.org type4 driver.
I wrote this jsp just for testing the environment when I deploy a web
app.
Goodluck, Andrew
<%--
FileName: testfreetdsjdbctype4driver.jsp
Purpose: To test the FREEDTS type 4 driver on a windows 2000 server, MS
SQL 7.0 and
TOMCAT 4.0 environement before deploying.

Driver Name:InternetCDS Type 4 JDBC driver for MS SQLServer
Driver Version:0.2 1
JDBC Driver properties:
freetds_jdbc.snapshot.2_0.jar - 9 March 2001, 2:04 AM
downloaded from
ftp://freetds.internetcds.com/pub/freetds_jdbc/
Copy the freetdsxxx.jar file into %CATALINA_HOME%\lib amd restart
Tomcat.
This file has been tested with MS SQL Server 7.0, on windows 2000
server,
using Apache Tomcat/4.0-b6.
It basically outputs a table showing all the databases defined on a
server
