XML and Oracle 8i Lite

Question

Hi Wizards
I'm in an endeavour to do the following things -
1.Generate XML output from Oracle 8i Lite database
2.Modify the XML and update the database taking the modified XML.
My java platform is JDK 1.2. I've used the XML SQL Utility for Java, and in doing so i've been successful with the 1st step. I've used the Oracle 8.1.6SDK JDBC Driver which is compatible with JDK 2.The code fragment is like the following -
import java.io.*;
import java.sql.*;
import java.math.*;
import oracle.xml.sql.query.*;
import oracle.jdbc.*;
import oracle.jdbc.driver.*;
public class orasql1
public static void main(String args[]) throws SQLException
Connection conn = null;
String tabName = "emp";
try {
Class.forName("oracle.lite.poljdbc.POLJDBCDriver");
conn = DriverManager.getConnection("jdbc:Polite:POlite", "SYSTEM", "manager");
catch (Exception e) {
System.out.println("Oracle Connection error\t:");
System.out.println(e);
System.exit(0);
OracleXMLQuery qry = new OracleXMLQuery(conn, "select * from " + tabName);
qry.setRowsetTag("SCHEMADOC_1");
qry.setRowTag("EMPLOYEE");
qry.setStyleSheet("emp.xsl");
String xmlString = qry.getXMLString(true);
conn.close();
try {
File output = new File("emp.xml");
FileWriter xmlFile = new FileWriter(output);
xmlFile.write(xmlString,0,xmlString.length());
xmlFile.close();
catch (Exception e) {
System.out.println("Output file error\t:");
System.out.println(e);
System.exit(0);
I am putting some sample code for step 2 in the following section -
import oracle.xml.sql.dml.*;
import java.sql.*;
import oracle.jdbc.driver.*;
import oracle.jdbc.*;
import java.net.*;
public class orasql2
public static void main(String args[]) throws SQLException
Connection conn = null;
String tabName = "emp";
String fileName = "emp.xml";
try {
Class.forName("oracle.lite.poljdbc.POLJDBCDriver");
conn = DriverManager.getConnection("jdbc:Polite:POlite", "SYSTEM", "manager");
catch (Exception e) {
System.out.println("An error has occurred.");
System.out.println("Please check your CLASSPATH variable..");
System.out.println(e);
System.exit(0);
OracleXMLSave save = new OracleXMLSave(conn, tabName);
URL url = save.createURL(fileName);
save.setRowTag("SCHEMADOC_1");
int rowCount = save.insertXML(url);
System.out.println("Successfully inserted "+rowCount+" rows into "+tabName);
conn.close();
Compiling the above code is fine, no errors! But while running the application I get the error -
Exception in thread "main" oracle.xml.sql.OracleXMLSQLException: java.lang.Class
CastException: oracle.lite.poljdbc.OracleStatement
at oracle.xml.sql.dml.OracleXMLSave.insertXML(OracleXMLSave.java:345)
at oracle.xml.sql.dml.OracleXMLSave.insertXML(OracleXMLSave.java:248)
at orasql2.main(orasql2.java:27)
My question is whether this thing can be done at all using Oracle 8i Lite? If so then how?
Waiting for ur advices.

Answer 1

It looks like be a classpath issue. Would you check with the class name.
