You can specify the character set to use in your application by setting the CHARSET driver property. If you do not set the CHARSET property:
For VERSION_2, jConnect uses iso_1 as the default character set.
For VERSION_3, VERSION_4, VERSION_5, and VERSION_6, jConnect uses the database’s default character set, and adjusts automatically to perform any necessary conversions on the client side.
You can also use the -J charset command line option for the IsqlApp application to specify a character set.
To determine which character sets are installed on your Adaptive Server, issue the following SQL query on your server:
select name from syscharsets go
For the PureConverter class, if the designated CHARSET does not work with the client’s Java Virtual Machine (VM), the connection fails with a SQLException, indicating that you must set CHARSET to a character set that is supported by both Adaptive Server and the client.
When the TruncationConverter class is used, character truncation is applied regardless of whether the designated CHARSET is 7-bit ASCII or not.
