Thank you Sir.
Now Jdbc Connection is established and perform the Transactions only sample programs.
I am also setting the classpath as you suggested previously in the Environment Variables.
What is the difference bitween setting the class path as command prompt and environment variables in Mycomputer properties in windows mode.

i had never expect raise this type of problams.

Once again Thank you very much.

could you know how to establish a connection pool in tomcat server using hibernate and spring frameworks. The database is Sql Server 2000.

Hibernate can do that using the C3PO pool implementation. Shouldn't take more than the appropriate entries in the hibernate.properties file. See this for further information.
