How can I execute a PL/SQL procedure for Oracle via JDBC?

I have a Java webapp with an Oracle DB, and I try to execute this statement at the end of a data migration script:

EXEC DBMS_STATS.GATHER_TABLE_STATS (ownname => 'MY_SCHEMA', tabname => 'MY_TABLE', estimate_percent => dbms_stats.auto_sample_size);

It works in sql*plus, but not via JDBC:

"Error: ORA-00900: invalid SQL statement"

What am I doing wrong?

Instead of EXEC, you should put it between begin ... end, or use the { call } syntax.
Here is an example, in the documentation:
