Hi Dean,
It might be something to do with connecting through oci8 to the
Oracle executable. ( I am not sure since I dont know ur
configuration etc..). BTW what release of Oracle is this?
One thing for you to try out would be to write a small java
program against the OracleXMLQuery class to see if that works.
I have attached a very simple program below:-
import java.sql.*;
import java.math.*;
import oracle.xml.sql.query.*;
import oracle.jdbc.*;
import oracle.jdbc.driver.*;
public class testXML{
public static void main(String args[]) throws SQLException
DriverManager.registerDriver
(new oracle.jdbc.driver.OracleDriver());
Connection conn = (Connection)
DriverManager.getConnection("jdbc:oracle:oci8:scott/tiger@");
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery("select * from emp");
OracleXMLQuery qry = new OracleXMLQuery(conn,rset);
String xmlString = qry.getXMLString();
System.out.println(" OUPUT IS "+xmlString);
This code does a select from emp table available in scott/tiger
schema. U can change the login and the table names
appropriately. SEtup all the environment variables etc.. (see
release notes), save this as testXML.java, run javac to get the
class and execute it using "java testXML". If this doesnt work,
try changing the getConnection line to use the thin jdbc, such
as,
DriverManager.getConnection
("jdbc:oracle:thin:@","scott","tiger");
You can check out the JDBC documentation for how to specify
your connection for your particular setup (such as specifying
the port number etc.. if needed).
Lemme know if it works,
