SQL string is not Query

Hi,
I have a problem...I have a j2ee application that execute with a JSP page a SQL QUERY this application execute query on DB with DB9i this application work but with DB10g don't work.
If I execute a SELECT query with the JDBC(jdbc driver for 9i) connect on DB10g the Query work but if I execute the INSERT or UPDATE query JSP don't work and I receving this error
"SQL string is not Query".
Why???
I write the source code of my JSP:
__________________________________

<%@page import="java.sql.*, java.io.*, javax.naming.*, javax.sql.*, oracle.jdbc.driver.*,java.util.*,java.net.*"%>

<%
//--------------------- DICHIRAZIONI VARIABILI NECESSARIE PER LA CONNESSIONE AL DB -----------
String dbase="jdbcracle:thin:@localhost:1521:test";


String login="test";
String pwd="test123";

// -------------------- DRIVER JDBC ----------------------------------------
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Class.forName("oracle.jdbc.driver.OracleDriver");

out.println("Test <br>");

String QueryProt = "INSERT INTO TEST_CEDA (ID) VALUES (?)";

Connection con_d;
PreparedStatement ps_d;
Statement stmt_d;
ResultSet rs_d;

String Prot="";
String Protoc="";


con_d = DriverManager.getConnection(dbase,login,pwd);
stmt_d = con_d.createStatement();
// rs_d = stmt_d.executeQuery(QueryProt,11);
ps_d=con_d.prepareStatement(QueryProt);
ps_d.setInt(1,100);
rs_d= ps_d.executeQuery();

if(rs_d.next())
{

//Prot=rs_d.getString("id");
rs_d.close();stmt_d.close();con_d.close();
//out.println("ciao "+Prot);
}

else
{
rs_d.close();stmt_d.close();con_d.close();
out.println("ciao no");
}

Why don't you try the new driver first? (i.e. 10g driver to 10g database?) I've experiences several problems using drivers that didn't match the db version.
See http://otn.oracle.com/software/tech...jdbc/index.html for downloads.

I have try tha install the driver jdbc10g on my ApplicationServer (I have copy the file, that I have download of your link,in the folder of my applicationServer)but these don't work.
I have a question the my JSPapplication can use the your driver 10g and don't use the driver10g of my ApplicationServer?

If you are using Tomcat you can put the jdbc driver in the /contextname/WEB-INF/lib folder where it will be available for that specific application only.

The drivers are correct. A "query" is a SELECT -- it returns a series of rowsets, INSERT, UPDATE and DELETE are DML statements, not queries, they don't return rowsets. If you want to execute DML you should call "execute" instead of "executeQuery". That's a lot easier than installing updated drivers.
