My Java application accesses an Oracle database via JDBC.
The Connection is established by the getConnection() method of a
OracleDataSource object.
This worked fine on all PCs with JRE 1.4.2.
With JRE 1.5.0_01 it doesn't work on some PCs while it still does on
most.
On those PCs where it doesn't work with JRE 1.5.0_01 it still does
work with JRE 1.4.2.
Where it doesn't work with JRE 1.5.0_01 the following SQLException is
thrown:

java.sql.SQLException: E/A-Exception: The Network Adapter could not
establish the connection

Any suggestions?
