Try if you can create DB connection with plain JDBC:

Please, include the whole stacktrace, not just selected pieces.

Yes, I know, but we have to examine if there is any problem in the lower layer.

Please, include the whole stacktrace, not just selected pieces.

You have executed it incorrectly. You should give the name of the Main class:

C:\test>java -cp c:\test\postgresql-8.3-603.jdbc4.jar;c:\test JDBCExample

Where JDBCExample is the class with main method.

No, because you do not have space between your classpath and Main class. You have just specified classpath.

You should try this:
C:\test>java -cp c:\test\postgresql-8.1-404.jdbc3.jar;c:\test JDBCExample

NOT
C:\test>java -cp c:\test\postgresql-8.1-404.jdbc3.jar;c:\test\JDBCExample.java
AND NOT
C:\test>java -cp c:\test\postgresql-8.1-404.jdbc3.jar;c:\test\JDBCExample

You have typed BAD command once again. Please, stay focused and type:

java -cp c:\test\postgresql-8.1-404.jdbc3.jar;c:\test JDBCExample

Pay attention to every single sign and space!

You SHOULD type:

OK, we are sure that your DB is accessible from the code.

You gave us the exception:
org.springframework.transaction.CannotCreateTransactionException : Could not open JPA EntityManager for transaction; nested exception is javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: Cannot open connection
null

Please paste the full stack trace despite the fact that it can be very long.
