is is possible to open a connection to a database with exclusive mode with JDBC?

I think you mean "lock a table in exclusive mode". You cannot open a connection with exclusive mode. Depending on your database engine, you can lock tables or rows in exclusive mode.

In Oracle you would create a statement st and run

st.execute("lock table mytable in exclusive mode");
Then when you are finished with the table, execute the commit to unlock the table. Mysql, informix and SQLServer all have a slightly different syntax for this function, so you'll have to change it depending on your database. But they can all be done with execute().
