I'm a student who needs help with a homework problem. The thing is that I wrote a rest web service using SAX parser in order to display a xml file that I have stored on the same folder of the project. The problem is that when I use the path I provided to it, it's not happening anything. I'm probably doing something wrong on my code. Here it is:
package com.crunchify.restjersey;
import java.io.IOException;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
@Path("/saxbooksxml")
public class SaxBooksXml {
public SaxBooksXml(){}
@GET
@Produces(MediaType.APPLICATION_XML)
public void gofindsaxbooks(){
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser saxParser = null;
try {
saxParser = factory.newSAXParser();
} catch (ParserConfigurationException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (SAXException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
DefaultHandler handler = new DefaultHandler(){
boolean bauthor = false;
boolean btitle = false;
boolean bgenre = false;
boolean bprice = false;
boolean bpublish_date = false;
boolean bdescription = false;
public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException{
if(qName.equalsIgnoreCase("author")){
bauthor = true;
}
if(qName.equalsIgnoreCase("title")){
btitle = true;
}
if(qName.equalsIgnoreCase("genre")){
bgenre = true;
}
if(qName.equalsIgnoreCase("price")){
bprice = true;
}
if(qName.equalsIgnoreCase("publish_date")){
bpublish_date = true;
}
if(qName.equalsIgnoreCase("description")){
bdescription = true;
}
}
public void endElement(String uri, String localName, String qName) throws SAXException{
}
public void characters(char ch[], int start, int lenght) throws SAXException{
if(bauthor){
System.out.println("author: "+new String(ch, start, lenght));
bauthor = false;
}
if(btitle){
System.out.println("title: "+new String(ch, start, lenght));
btitle = false;
}
if(bgenre){
System.out.println("genre: "+new String(ch, start, lenght));
bgenre = false;
}
if(bprice){
System.out.println("price: "+new String(ch, start, lenght));
bprice = false;
}
if(bpublish_date){
System.out.println("publish_date: "+new String(ch, start, lenght));
bpublish_date = false;
}
if(bdescription){
System.out.println("description: "+new String(ch, start, lenght)+"\n");
bdescription = false;
}
}
};
try {
saxParser.parse("Books.xml", handler);
} catch (SAXException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
This is a print of part of the file I'm trying to parse. The idea is to display it on the browser exactly the same.
Mike Adamenko :
Your method gofindsaxbooks returns void
Change it like below:
@GET
@Produces(MediaType.APPLICATION_XML)
public Response gofindsaxbooks()
{
return Response.status(200).entity("Test XML created").build();
}
