Calling PL\SQL procedures

Question

What's the best way to invoke a PL\SQL procedure using Java?
I am hoping to use the values passed from the JSP into the database for computations but don't know how to call the procedure after the commit.
Any ideas?
Thanks a lot!

Example follows for a PL/SQL proc call from a Java application that returns a result set and displays it in a scrolling pane. Hope it helps you:
setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
try
CallableStatement call =
OpenDBConnections.myJdbcConnection.prepareCall
("{? = call MY_PLSQL_PROC(?)}");
call.registerOutParameter(1,OracleTypes.CURSOR);
call.setString(2,partNumber_tf.getText().toString());
call.execute();
OracleResultSet rset=(OracleResultSet)call.getObject(1);
/* use caching result set cuz it is non scrollable stored proc result */
model = new CachingResultSetTableModel(rset);
result_tbl = new JTable(model);
status_tf.setText(result_tbl.getRowCount()+" matching Rows found.");
jScrollPane1.getViewport().add(result_tbl, null);
rset.close();
call.close();
setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
catch (SQLException esql)
System.out.println(esql.toString());
}
