Problems with XML parsing

[dmjpro]

I am trying to parse a XML file with JAXP.
Now what's happening to me ..that ..... the XML file is having some DTD which specifies a site DTD definition ....
<!DOCTYPE jasperReport PUBLIC "//JasperReports//DTD Report Design//EN" "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">
So right now Connection refused error is coming.
I know why it's coming .... But I want to put off the DTD parsing how could i do that.
One more thing if a DTD is of site then having no net connection validation can't be done ...????
What should be validation code for that .....

Turn off validation when you create the DocumentBuilderFactory.

factory.setValidating(false)

As for your second question, the answer is too complicated to type here :). It involves creating your own Resolver class to serve the dtd from your machine instead of the parser having to connect to the internet.

Thanks for your reply!
I am now having this code ...

       DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
       factory.setValidating(false);
       DocumentBuilder jrxml = factory.newDocumentBuilder();
       FileInputStream is = new FileInputStream(file);
       Document jrxml_doc = jrxml.parse(is);
 

Still the error is coming.
What should I do?

If you had read the API documentation you'd have known that by default that factory
produces non-validating parsers so the error must be somewhere else. Please
read before you start ask questions here and hope that others will do your work
for you. This entire thread has been useless until now because of that non-validating
default behaviour and you simply didn't know that because you haven't read the
API documentation.

kind regards,

Jos

Yeah it's OK ......
Connection Refused Exception coming.
It tries to connect that DTD resource .....
How could I solve that?

Try something like

documentBuilder.setEntityResolver(resolver);

where resolver is your own custom Resolver class implementing the org.xml.sax.EntityResolver interface. The implementation should read from your local file on disk and return the dtd (or schema). Am sure you can figure out how.

I need not to check whether it matches with DTD or not .....
I just want to bypass the DTD parsing .
I managed to do that ...by doing this ..

jrxml.setEntityResolver(new EntityResolver() {
            public InputSource resolveEntity(String publicId, String systemId) throws SAXException,IOException {
                //return new InputSource("http://jasperreports.sourceforge.net/dtds/jasperreport.dtd");
                return new InputSource(new ByteArrayInputStream(new byte[0]));
            }
        });
 

Thanks Jos and Thanks Others.
