error while passing parameter to PL/SQL procedure

Hello ,

this is a method wich try to pass a string to simple PL/SQL stored procedure:

public static void call_AudStatscrutJOB(String objectName){

ResultSet ping = null;
boolean test1 = false;
// CallableStatement cstmt = null;
PreparedStatement cstmt = null;
float nb_statement=0;

TestConnection conn = new TestConnection();
Connection connection = null;

try{
connection=conn.connect();
if (connection != null)
{
cstmt = connection.prepareStatement("{call manage_pak.test2(?)}");
cstmt.setString(1,"EMP");
cstmt.addBatch();
cstmt.executeBatch();
}
else System.out.println("Connection closed");

}
catch (SQLException sqle) {sqle.printStackTrace();}
try{
if ( !connection.isClosed() )
{
connection.close();
}
}
catch (SQLException sqle) {sqle.printStackTrace();}
}

i've got this probleme when calling the procedure:

ORA-00911: caractère non valide

I try the same code without passing parameter, it works. I think the probleme is about the '?' caracter. Someone can help me please

WHy do you want to pass "?" ?

Tamil

well , in fact, i want to pass a string : "EMP". But i see that to pass parameters to a PL/SQL procedure from java programme, we must bind the parameter with the '?' caracter when we call the procedure
