Here’s how you do it. Remember, the last parameter in my example is actually declared in the PL/SQL procedure as an “OUT” parameter, e.g. the value you want to return in the form of a parameter):

conn — is the connection object

cstmt — this is a callablestatement

   cstmt = conn.getNewCallableStatement("{call MY_PLSQL_PACKAGE.MY_PROC(?,?,?)}");
           cstmt.setString(1, stringOutput1);
           cstmt.setString(2, stringOutput2);
           cstmt.registerOutParameter(3, OracleTypes.CURSOR);
           cstmt.execute;
